Doctor, doctor: What can British GPs do about problem gambling?

A study published in the British Journal of General Practice in March 2017 reported that of 1,058 individuals surveyed in GP waiting rooms in Bristol (UK), 0.9% were problem gamblers and that a further 4.3% reported gambling problems that “were low to medium severity”. This is in line with other British studies carried out over the last decade which have reported problem gambling prevalence rates of between 0.5% and 0.9%.

I have long argued that problem gambling is a health issue and that GPs should routinely screen for gambling problems. Back in 2004, I published an article in the British Medical Journal about why problem gambling is a health issue. I argued that the social and health costs of problem gambling were (and still are) large at both individual and societal levels.


Personal costs can include irritability, extreme moodiness, problems with personal relationships (including divorce), absenteeism from work, neglect of family, and bankruptcy. Adverse health consequences for problem gamblers and their partners include depression, insomnia, intestinal disorders, migraine, and other stress related disorders. In my BMJ article I also noted that analysis of calls to the GamCare national gambling helpline indicated that a small minority of callers reported health-related consequences as a result of their problematic gambling. These included depression, anxiety, stomach problems, and suicidal ideation. Obviously many of these medical problems arise through the stress of financial problems but that doesn’t make it any less of a health issue for those suffering from severe gambling problems.

Research published in the American Journal of Addictions has also shown that health-related problems can occur as a result of withdrawal effects. For instance, one study by Dr. Richard Rosenthal and Dr. Henry Lesieur found that at least 65% of pathological gamblers reported at least one physical side effect during withdrawal, including insomnia, headaches, loss of appetite, physical weakness, heart racing, muscle aches, breathing difficulty, and chills.

Based on these findings, problem gambling is very much a health issue that needs to be taken seriously by all in the medical profession. GPs routinely ask patients about smoking cigarettes and drinking, but gambling is something that is not generally discussed. Problem gambling may be perceived as a grey area in the field of health, and it is therefore very easy for those in the medical profession not to have the issue on their wellbeing radar. If the main aim of GPs is to ensure the health of their patients, then an awareness of gambling and the issues surrounding it should be an important part of basic knowledge and should be taught in the curriculum while prospective doctors are at medical school. One of the reasons that GPs don’t routinely screen for problem gambling is because they are not taught about it during their medical training and therefore do not even think about screening for it in the first place. As I recommended in a report commissioned by the British Medical Association, the need for education and training in the diagnosis, appropriate referral and effective treatment of gambling problems must be addressed within GP training. More specifically, GPs should be aware of the types of gambling and problem gambling, demographic and cultural differences, and the problems and common co-morbidities associated with problem gambling. GPs should also understand the importance of screening patients perceived to be at increased risk of gambling addiction, and should be aware of the referral and support services available locally.

I also recommended that treatment for problem gambling should be provided under the NHS (either as standalone services or alongside drug and alcohol addiction services) and funded by gambling-derived profit revenue.

Back in 2011, Dr. Jane Rigbye and myself published a study using Freedom of Information requests to ask NHS trusts if they had ever treated pathological gamblers. Only 3% of the trusts had ever treated a problem gambler and only one trust said they offered dedicated help and support. I’m sure if we repeated the study today, little will have changed.

It is evident that problem gambling is not, as yet, on the public health agenda in the UK. NHS services – including GP surgeries – need to be encouraged to see gambling problems as a primary reason for referral and a valid treatment option. Information about gambling addiction services, in particular services in the local area, should be readily available to gamblers and GP surgeries are a good outlet to advertise such services. Although some gambling services (such as GamCare, the gambling charity I co-founded) provide information to problem gamblers about local services, such information is provided to problem gamblers who have already been proactive in seeking gambling help and/or information. Given that very few GPs could probably treat a problem gambler, what they must have is the knowledge of who they can refer their patients to.

Search of the poisoned mind? A brief look at ‘internet search dependence’

Despite being a controversial topic, research into a wide variety of online addictions has grown substantially over the last decade. My own research into online addictions has been wide ranging and has included online social networking, online sex addiction, online gaming addiction, online shopping addiction, and online gambling addiction. As early as the late 1990s/early 2000s, I constantly argued that when it came to online addictions, most of those displaying problematic behaviour had addictions on the internet rather than addictions to the internet (i.e., they were not addicted to the medium of the internet but addicted to applications and activities that could be engaged in via the internet).

A recent 2016 paper by Dr. Yifan Wang and colleagues in the journal Frontiers in Public Health described the development of the Questionnaire of Internet Search Dependence (QISD), a tool developed to assess individuals who may be displaying a dependence on using online search engines (such as Google and Baidu). The notion of individuals being addicted to using search engines is not new and was one of five types of internet addiction outlined in a 1999 typology in a paper in the Student British Medical Journal by Dr. Kimberley Young (and what she termed ‘information overload’ and referred to compulsive database searching). Although I criticized the typology on the grounds that most of the types of online addict were not actually internet addicts but were individuals using the medium of the internet to fuel other addictive behaviours (e.g., gambling, gaming, day trading, etc.), I did implicitly acknowledge that activities such as internet database searching could theoretically exist, even if I did not think it was a type of internet addiction.


As far as I am aware, the new scale developed by Wang et al. (2016) is the first to create and psychometrically evaluate an instrument to assess ‘internet search dependence’. As noted by the authors:

Subsequently, we compiled 16 items to represent psychological characteristics associated with Internet search dependence, based on the literature review and a follow-up interview with 50 randomly selected university students…We adopted the six criteria for behavioral addiction formulated by Griffiths (i.e., salience, mood modification, tolerance, withdrawal, conflict, and relapse) [Griffiths, 1999b]”.

Given the authors claimed they used an early version of my addiction components model (i.e., one from 1999 rather than my most recent 2005 formulation) to help inform item construction, I was obviously interested to see the scale’s formulated items. I have to admit that I had a lot of misgivings about the paper so I wrote a commentary on it that has just been published in the same journal (Frontiers in Public Health). More specifically, I noted in my paper that if an individual was genuinely addicted to searching online databases I would have expected to see all of my six criteria applied as follows:

  • Salience – This occurs when searching internet databases becomes the single most important activity in the person’s life and dominates their thinking (preoccupations and cognitive distortions), feelings (cravings) and behaviour (deterioration of socialized behaviour). For instance, even if the person is not actually searching the internet they will be constantly thinking about the next time that they will be (i.e., a total preoccupation with internet database searching).
  • Mood modification – This refers to the subjective experiences that people report as a consequence of internet database searching and can be seen as a coping strategy (i.e., they experience an arousing ‘buzz’ or a ‘high’ or paradoxically a tranquilizing feel of ‘escape’ or ‘numbing’ when searching internet databases).
  • Tolerance – This is the process whereby increasing amounts of time searching internet databases are required to achieve the former mood modifying effects. This basically means that for someone engaged in internet database searching, they gradually build up the amount of the time they spend searching internet databases every day.
  • Withdrawal symptoms – These are the unpleasant feeling states and/or physical effects (e.g., the shakes, moodiness, irritability, etc.), that occur when an individual is unable to search internet databases because they are ill, the internet is unavailable, or there is no Wi-Fi on holiday, etc.
  • Conflict – This refers to the conflicts between the person and those around them (interpersonal conflict), conflicts with other activities (social life, hobbies and interests) or from within the individual themselves (intra-psychic conflict and/or subjective feelings of loss of control) that are concerned with spending too much time searching internet databases.
  • Relapse – This is the tendency for repeated reversions to earlier patterns of excessive internet database searching to recur and for even the most extreme patterns typical of the height of excessive internet database searching to be quickly restored after periods of control.

Of the 12 QISD items constructed in the new scale, very few appeared to have anything to do with addiction and/or dependence but this is most likely due to the fact that the authors also used data collected from 50 participants to inform their items and not just the criteria in the addiction components model. However, relying heavily on input from their participants resulted in a number of key features in addiction/dependence not even being assessed (i.e., no assessment of salience, mood modification, conflict, relapse or tolerance). A couple of items may peripherally assess withdrawal symptoms (e.g., ‘I will be upset if I cannot find an answer to a complex question through Internet search’) but not in any way that is directly associated with addiction or dependence. This may be because the authors’ conceptualization of ‘dependence’ was more akin to ‘over-reliance’ rather than traditional definitions of dependence.

While the QISD may be psychometrically robust I argued that it appears to have little face validity and does not appear to assess problematic engagement in internet database searching (irrespective of how addiction or dependence is defined). Based on the addiction components model, I concluded my paper by creating my own scale to assess internet search dependence based directly on the addiction components model and which I argued would have much greater face validity than any item currently found in the QISD:

  • Internet database searching is the most important thing in my life.
  • Conflicts have arisen between me and my family and/or my partner about the amount of time I spend searching internet databases.
  • I engage in internet database searching as a way of changing my mood.
  • Over time I have increased the amount of internet database searching I do in a day.
  • If I am unable to engage in internet database searching I feel moody and irritable.
  • If I cut down the amount of internet database searching I do, and then start again, I always end up searching internet databases as often as I did before.

A diction for addiction: A brief overview of our papers at the 2017 International Conference on Behavioral Addictions

This week I attended (and gave one of the keynote papers at) the fourth International Conference on Behavioral Addictions in Haifa (Israel). It was a great conference and I was accompanied by five of my colleagues from Nottingham Trent University all of who were also giving papers. All of the conference abstracts have just been published in the latest issue of the Journal of Behavioral Addictions (reprinted below in today’s blog) and if you would like copies of the presentations then do get in touch with me.


Griffiths, M.D. (2017). Behavioural tracking in gambling: Implications for responsible gambling, player protection, and harm minimization. Journal of Behavioral Addictions, 6 (Supplement 1), 2.

  • Social responsibility, responsible gambling, player protection, and harm minimization in gambling have become major issues for both researchers in the gambling studies field and the gaming industry. This has been coupled with the rise of behavioural tracking technologies that allow companies to track every behavioural decision and action made by gamblers on online gambling sites, slot machines, and/or any type of gambling that utilizes player cards. This paper has a number of distinct but related aims including: (i) a brief overview of behavioural tracking technologies accompanied by a critique of both advantages and disadvantages of such technologies for both the gaming industry and researchers; (ii) results from a series of studies carried out using behavioural tracking (particularly in relation to data concerning the use of social responsibility initiatives such as limit setting, pop-up messaging, and behavioural feedback); and (c) a brief overview of the behavioural tracking tool mentor that provides detailed help and feedback to players based on their actual gambling behaviour.

Calado, F., Alexandre, J. & Griffiths, M.D. (2017). Youth problem gambling: A cross-cultural study between Portuguese and English youth. Journal of Behavioral Addictions, 6 (Supplement 1), 7.

  • Background and aims: In spite of age prohibitions, most re- search suggests that a large proportion of adolescents engage in gambling, with a rate of problem gambling significantly higher than adults. There is some evidence suggesting that there are some cultural variables that might explain the development of gambling behaviours among this age group. However, cross­cultural studies on this field are generally lacking. This study aimed to test a model in which individual and family variables are integrated into a single perspective as predictors of youth gambling behaviour, in two different contexts (i.e., Portugal and England). Methods: A total of 1,137 adolescents and young adults (552 Portuguese and 585 English) were surveyed on the measures of problem gambling, gambling frequency, sensation seeking, parental attachment, and cognitive distortions. Results: The results of this study revealed that in both Portuguese and English youth, the most played gambling activities were scratch cards, sports betting, and lotteries. With regard to problem gambling prevalence, English youth showed a higher prevalence of problem gambling. The findings of this study also revealed that sensation seeking was a common predictor in both samples. However, there were some differences on the other predictors be- tween the two samples. Conclusions: The findings of this study suggest that youth problem gambling and its risk factors appear to be influenced by the cultural context and highlights the need to conduct more cross-cultural studies on this field.

A new tool to assess the psychological features of reward deficiency. Journal of Behavioral Addictions, 6 (Supplement 1), 11.

  • ‘Reward Deficiency Syndrome’ (RDS) is a theory assuming that specific individuals do not reach a satisfactory state of reward due to the functioning of their hypodopaminergic reward system. For this reason, these people search for further rewarding stimuli in order to stimulate their central reward system (i.e., extreme sports, hypersexuality, substance use and/or other addictive behaviors such as gambling, gaming, etc.). Beside the growing genetic and neurobiological evidence regarding the existence of RDS little re- search has been done over the past two decades on the psychological processes behind this phenomenon. The aim of the present paper is to provide a psychological description of RDS as well as to present the development of the Reward Deficiency Syndrome Questionnaire (developed using a sample of 1,726 participants), a new four-factor instrument assessing the different aspects of reward deficiency. The results indicate that four specific factors contribute to RDS comprise “lack of satisfaction”, “risk seeking behaviors”, “need for being in action”, and “search for overstimulation”. The paper also provides psychological evidence of the association between reward deficiency and addictive disorders. The findings demonstrate that the concept of RDS provides a meaningful and theoretical useful context to the understanding of behavioral addictions.

  • Background and aims: The Ten-Item Internet Gaming Disorder Test (IGDT-10) is a brief instrument developed to assess Internet Gaming Disorder as proposed in the DSM­5. The first psychometric analyses carried out among a large sample of Hungarian online gamers demonstrated that the IGDT-10 is a valid and reliable instrument. The present study aimed to test the psychometric properties in a large cross-cultural sample. Methods: Data were collected among Hungarian (n = 5222), Iranian (n = 791), Norwegian (n = 195), Czech (n = 503), Peruvian (n = 804), French­speaking (n = 425) and English­ speaking (n = 769) online gamers through gaming­related websites and gaming-related social networking site groups. Results: Confirmatory factor analysis was applied to test the dimensionality of the IGDT-10. Results showed that the theoretically chosen one-factor structure yielded appropriate to the data in all language­based subsamples. In addition, results indicated measurement invariance across all language-based subgroups and across gen- der in the total sample. Reliability indicators (i.e., Cronbach’s alpha, Guttman’s Lambda-2, and composite reliability) were acceptable in all subgroups. The IGDT- 10 had a strong positive association with the Problematic Online Gaming Questionnaire and was positively and moderately related to psychopathological symptoms, impulsivity and weekly game time supporting the construct validity of the instrument. Conclusions: Due to its satisfactory psychometric characteristics, the IGDT-10 appears to be an adequate tool for the assessment of internet gam- ing disorder as proposed in the DSM-5.

Throuvala, M.A., Kuss, D.J., Rennoldson, M. & Griffiths, M.D. (2017). Delivering school-based prevention regarding digital use for adolescents: A systematic review in the UK. Journal of Behavioral Addictions, 6 (Supplement 1), 54.

  • Background: To date, the evidence base for school-delivered prevention programs for positive digital citizenship for adolescents is limited to internet safety programs. Despite the inclusion of Internet Gaming Disorder (IGD) as a pro- visional disorder in the DSM-5, with arguable worrying prevalence rates for problematic gaming across countries, and a growing societal concern over adolescents’ digital use, no scientifically designed digital citizenship programs have been delivered yet, addressing positive internet use among adolescents. Methods: A systematic database search of quantitative and qualitative research evidence followed by a search for governmental initiatives and policies, as well as, non­profit organizations’ websites and reports was conducted to evaluate if any systematic needs assessment and/or evidence-based, school delivered prevention or intervention programs have been conducted in the UK, targeting positive internet use in adolescent populations. Results: Limited evidence was found for school-based digital citizenship awareness programs and those that were identified mainly focused on the areas of internet safety and cyber bullying. To the authors’ knowledge, no systematic needs assessment has been conducted to assess the needs of relevant stakeholders (e.g., students, parents, schools), and no prevention program has taken place within UK school context to address mindful and positive digital consumption, with the exception of few nascent efforts by non­profit organizations that require systematic evaluation. Conclusions: There is a lack of systematic research in the design and delivery of school-delivered, evidence-based prevention and intervention programs in the UK that endorse more mindful, reflective attitudes that will aid adolescents in adopting healthier internet use habits across their lifetime. Research suggests that adolescence is the highest risk group for the development of internet addictions, with the highest internet usage rates of all age groups. Additionally, the inclusion of IGD in the DSM-5 as provisional disorder, the debatable alarming prevalence rates for problematic gaming and the growing societal focus on adolescents’ internet misuse, renders the review of relevant grey and published research timely, contributing to the development of digital citizenship programs that might effectively promote healthy internet use amongst adolescents.

  • Despite being one of the most popular activities among adolescents nowadays, robust measures of Social Media use and representative prevalence estimates are lacking in the field. N = 5961 adolescents (49.2% male; mean age 16.6 years) completed our survey. Results showed that the one-factor Bergen Social Media Addiction Scale (BSMAS) has appropriate psychometric properties. Based on latent pro le analysis, 4.5% of the adolescents belonged to the at-risk group, who reported low self-esteem, high level of depression and the elevated social media use (34+ hours a week). Conclusively, BSMAS is an adequate measure to identify those adolescents who are at risk of problematic Social Media use and should therefore be targeted by school-based prevention and intervention programs.

  • Background and aims: To our best knowledge, no scale ex- ists with strong psychometric properties assessing problematic pornography consumption which is based on an over- arching theoretical background. The goal of the present study was to develop a short scale (Problematic Pornography Consumption Scale; PPCS) on the basis of Griffiths` (2005) six-component addiction model that can assess problematic pornography consumption. Methods: The sample comprised 772 respondents (390 females; Mage = 22.56, SD = 4.98 years). Items creation was based on the definitions of the components of Griffiths’ model. Results: A confirmatory factor analysis was carried out leading to an 18­item second­order factor structure. The reliability of the PPCS was good and measurement invariance was established. Considering the sensitivity and specificity values, we identified an optimal cut­off to distinguish between problematic and non-problematic pornography users. In the present sample, 3.6% of the pornography consumers be- longed to the at-risk group. Discussion and Conclusion: The PPCS is a multidimensional scale of problematic pornography consumption with strong theoretical background that also has strong psychometric properties.

The words and the we’s: When is a new addiction scale not a new addiction scale?

“The words you use should be your own/Don’t plagiarize or take on loans/There’s always someone, somewhere/With a big nose, who knows” (Lyrics written by Morrissey from ‘Cemetry Gates’ (sic) by The Smiths)

Over the last few decades, research into ‘shopping addiction’ and ‘compulsive buying’ has greatly increased. In 2015, I along with my colleagues, developed and subsequently published (in the journal Frontiers in Psychology) a new scale to assess shopping addiction – the 7-item Bergen Shopping Addiction Scale (BSAS) which I wrote about in one of my previous blogs.

We noted in our Frontiers in Psychology paper that two scales had already been developed in the 2000s (i.e., one by Dr. George Christo and colleagues in 2003, and one by Dr. Nancy Ridgway and colleagues in 2008 – see ‘Further reading’ below), but that neither of these two instruments approached problematic shopping behaviour as an addiction in terms of core addiction criteria that are often used in the behavioural addiction field including salience, mood modification, tolerance, withdrawal, conflict, relapse, and problems. We also made the point that new Internet-related technologies have now greatly facilitated the emergence of problematic shopping behaviour because of factors such as accessibility, affordability, anonymity, convenience, and disinhibition, and that there was a need for a psychometrically robust instrument that assessed problematic shopping across all platforms (i.e., both online and offline). We concluded that the BSAS has good psychometrics, structure, content, convergent validity, and discriminative validity, and that researchers should consider using it in epidemiological studies and treatment settings concerning shopping addiction.


More recently, Srikant Amrut Manchiraju, Sadachar and Jessica Ridgway developed something they called the Compulsive Online Shopping Scale (COSS) in the International Journal of Mental Health and Addiction (IJMHA). Given that we had just developed a new shopping addiction scale that covered shopping across all media, we were interested to read about the new scale. The scale was a 28-item scale and was based on the 28 items included in the first step of BSAS development (i.e., initial 28-item pool). As the authors noted:

“First, to measure compulsive online shopping, we adopted the Bergen Shopping Addiction Scale (BSAS; Andreassen, 2015). The BSAS developed by Andreassen et al. (2015), was adapted for this study because it meets the addiction criteria (e.g., salience, mood modification, etc.) established in the DSM-5. In total, 28 items from the BSAS were modified to reflect compulsive online shopping. For example, the original item – ‘Shopping/buying is the most important thing in my life’ was modified as ‘Online shopping/buying is the most important thing in my life’… It is important to note that we are proposing a new behavioral addiction scale, specifically compulsive online shopping … In conclusion, the scale developed in this study demonstrated strong psychometric, structure, convergent, and discriminant validity, which is consistent with Andreassen et al.’s (2015) findings”.

Apart from the addition of the word ‘online’ to every item, all initial 28 items of the BSAS were used identically in the COSS. Therefore, I sought the opinion of several research colleagues about the ‘new’ scale. Nearly all were very surprised that an almost identical scale had been published. Some even questioned whether such wholescale use might constitute plagiarism (particularly as none of the developers of the COSS sought permission to adapt our scale).

According to the website, several forms of plagiarism have been described including: “Copying so many words or ideas from a source that it makes up the majority of your work, whether you give credit or not” (p.1). Given the word-for-word reproduction of the 28 item–pool, an argument could be made that the COSS plagiarizes the BSAS, even though the authors acknowledge the source of their scale items. According to Katrina Korb’s 2012 article on adopting or adapting psychometric instruments:

“Adapting an instrument requires more substantial changes than adopting an instrument. In this situation, the researcher follows the general design of another instrument but adds items, removes items, and/or substantially changes the content of each item. Because adapting an instrument is similar to developing a new instrument, it is important that a researcher understands the key principles of developing an instrument…When adapting an instrument, the researcher should report the same information in the Instruments section as when adopting the instrument, but should also include what changes were made to the instrument and why” (p.1).

Dr. Manchiraju and his colleagues didn’t add or remove any of the original seven items, and did not substantially change the content of any of the 28 items on which the BSAS was based. They simply added the word ‘online’ to each existing item. Given that the BSAS was specifically developed to take into account the different ways in which people now shop and to include both online and offline shopping, there doesn’t seem to be a good rationale for developing an online version of the BSAS. Even if there was a good rationale, the scale could have made reference to the Bergen Shopping Addiction Scale in the name of the ‘new’ instrument. In a 2005 book chapter ‘Selected Ethical Issues Relevant to Test Adaptations’ by Dr. Thomas Oakland (2005), he noted the following in relation to plagiarism and psychometric test development:

Psychologists do not present portions of another’s work or data as their own, even if the other work or data source is cited … Plagiarism occurs commonly in test adaptation work (Oakland & Hu, 1991), especially when a test is adapted without the approval of its authors and publisher. Those who adapt a test by utilizing items from other tests without the approval of authors and publishers are likely to be violating ethical standards. This practice should not be condoned. Furthermore, this practice may violate laws in those countries that provide copyright protection to intellectual property. In terms of scale development, a measure that has the same original items with only one word added to each item (which only adds information on the context but does not change the meaning of the item) does not really constitute a new scale. They would find it really hard to demonstrate discriminant validity between the two measures”.

Again, according to Oakland’s description of plagiarism specifically in relation to the development of psychometric tests (rather than plagiarism more generally), the COSS appears to have plagiarized the BSAS particularly as Oakland makes specific reference to the adding of one word to each item (“In terms of scale development, a measure that has the same original items with only one word added to each item … does not really constitute a new scale”).

Still, it is important to point that I have no reason to think that this use of the BSAS was carried out maliciously. Indeed, it may well be that the only wrongdoing was lack of familiarity with the conventions of psychometric scale development. It may be that the authors took one line in our original Frontiers in Psychology paper too literally (the BSAS may be freely used by researchers in their future studies in this field”). However, the purpose of this sentence was to give fellow researchers permission to use the validated scale in their own studies and to avoid the inconvenience of having to request permission to use the BSAS and then waiting for an answer. Another important aspect here is that the BSAS (which may be freely used) consists of seven items only, not 28. The seven BSAS items were extracted from an initial item pool in accordance with our intent to create a brief shopping addiction scale. Consequently, there exists only one version of BSAS, the 7-item version. Here, Dr. Manchiraju and his colleagues seem to have misinterpreted this when referring to a 28-item BSAS.

Surprise, surprise: A brief overview of our recent papers on strange addictions and behaviours

Following my recent blogs where I outlined some of the papers that my colleagues and I have published on mindfulness, Internet addiction, gaming addiction, youth gambling, workaholism, exercise addiction, and sex addiction, here is a round-up of recent papers that my colleagues and I have published on strange and/or surprising addictions and behaviours.

Foster, A.C., Shorter, G.W. & Griffiths, M.D. (2015). Muscle Dysmorphia: Could it be classified as an Addiction to Body Image? Journal of Behavioral Addictions, 4, 1-5.

  • Background: Muscle dysmorphia (MD) describes a condition characterised by a misconstrued body image in which individuals who interpret their body size as both small or weak even though they may look normal or highly muscular. MD has been conceptualized as a type of body dysmorphic disorder, an eating disorder, and obsessive–compulsive disorder symptomatology. Method and aim: Through a review of the most salient literature on MD, this paper proposes an alternative classification of MD – the ‘Addiction to Body Image’ (ABI) model – using Griffiths (2005) addiction components model as the framework in which to define MD as an addiction. Results: It is argued the addictive activity in MD is the maintaining of body image via a number of different activities such as bodybuilding, exercise, eating certain foods, taking specific drugs (e.g., anabolic steroids), shopping for certain foods, food supplements, and the use or purchase of physical exercise accessories). In the ABI model, the perception of the positive effects on the self-body image is accounted for as a critical aspect of the MD condition (rather than addiction to exercise or certain types of eating disorder). Conclusions: Based on empirical evidence to date, it is proposed that MD could be re-classified as an addiction due to the individual continuing to engage in maintenance behaviours that may cause long-term harm.

Griffiths, M.D., Foster, A.C. & Shorter, G.W. (2015). Muscle dysmorphia as an addiction: A response to Nieuwoudt (2015) and Grant (2015). Journal of Behavioral Addictions, 4, 11-13.

  • Background: Following the publication of our paper ‘Muscle Dysmorphia: Could it be classified as an addiction to body image?’ in the Journal of Behavioral Addictions, two commentaries by Jon Grant and Johanna Nieuwoudt were published in response to our paper. Method: Using the ‘addiction components model’, our main contention is that muscle dysmorphia (MD) actually comprises a number of different actions and behaviors and that the actual addictive activity is the maintaining of body image via a number of different activities such as bodybuilding, exercise, eating certain foods, taking specific drugs (e.g., anabolic steroids), shopping for certain foods, food supplements, and purchase or use of physical exercise accessories. This paper briefly responds to these two commentaries. Results: While our hypothesized specifics relating to each addiction component sometimes lack empirical support (as noted explicitly by both Nieuwoudt and Grant), we still believe that our main thesis (that almost all the thoughts and behaviors of those with MD revolve around the maintenance of body image) is something that could be empirically tested in future research by those who already work in the area. Conclusions: We hope that the ‘Addiction to Body Image’ model we proposed provides a new framework for carrying out work in both empirical and clinical settings. The idea that MD could potentially be classed as an addiction cannot be negated on theoretical grounds as many people in the addiction field are turning their attention to research in new areas of behavioral addiction.

Maraz, A., Király, O., Urbán, R., Griffiths, M.D., Demetrovics, Z. (2015). Why do you dance? Development of the Dance Motivation Inventory (DMI). PLoS ONE, 10(3): e0122866. doi:10.1371/ journal.pone.0122866

  • Dancing is a popular form of physical exercise and studies have show that dancing can decrease anxiety, increase self-esteem, and improve psychological wellbeing. The aim of the current study was to explore the motivational basis of recreational social dancing and develop a new psychometric instrument to assess dancing motivation. The sample comprised 447 salsa and/or ballroom dancers (68% female; mean age 32.8 years) who completed an online survey. Eight motivational factors were identified via exploratory factor analysis and comprise a new Dance Motivation Inventory: Fitness, Mood Enhancement, Intimacy, Socialising, Trance, Mastery, Self-confidence and Escapism. Mood Enhancement was the strongest motivational factor for both males and females, although motives differed according to gender. Dancing intensity was predicted by three motivational factors: Mood Enhancement, Socialising, and Escapism. The eight dimensions identified cover possible motives for social recreational dancing, and the DMI proved to be a suitable measurement tool to assess these motives. The explored motives such as Mood Enhancement, Socialising and Escapism appear to be similar to those identified in other forms of behaviour such as drinking alcohol, exercise, gambling, and gaming.

  • Although recreational dancing is associated with increased physical and psychological well-being, little is known about the harmful effects of excessive dancing. The aim of the present study was to explore the psychopathological factors associated with dance addiction. The sample comprised 447 salsa and ballroom dancers (68% female, mean age: 32.8 years) who danced recreationally at least once a week. The Exercise Addiction Inventory (Terry, Szabo, & Griffiths, 2004) was adapted for dance (Dance Addiction Inventory, DAI). Motivation, general mental health (BSI-GSI, and Mental Health Continuum), borderline personality disorder, eating disorder symptoms, and dance motives were also assessed. Five latent classes were explored based on addiction symptoms with 11% of participants belonging to the most problematic class. DAI was positively associated with psychiatric distress, borderline personality and eating disorder symptoms. Hierarchical linear regression model indicated that Intensity (ß=0.22), borderline (ß=0.08), eating disorder (ß=0.11) symptoms, as well as Escapism (ß=0.47) and Mood Enhancement (ß=0.15) (as motivational factors) together explained 42% of DAI scores. Dance addiction as assessed with the Dance Addiction Inventory is associated with indicators of mild psychopathology and therefore warrants further research.


Greenhill, R. & Griffiths, M.D. (2015). Compassion, dominance/submission, and curled lips: A thematic analysis of dacryphilic experience. International Journal of Sexual Health, 27, 337-350.

  • Objectives: Dacryphilia is a non-normative sexual interest that involves enjoyment or arousal from tears and crying, and to date has never been researched empirically. The present study set out to discover the different interests within dacryphilia and explore the range of dacryphilic experience. Methods: A set of online interviews were carried out with individuals with dacryphilic preferences and interests (six females and two males) from four countries. The data were analyzed for semantic and latent themes using thematic analysis. Results: The respondents’ statements focused attention on three distinct areas that may be relevant to the experience of dacryphilia: (i) compassion; (ii) dominance/submission; and (iii) curled-lips. The data provided detailed descriptions of features within all three interests, which are discussed in relation to previous quantitative and qualitative research within emotional crying and tears, and the general area of non-normative sexual interests. Conclusions: The study suggests new directions for potential research both within dacryphilia and with regard to other non-normative sexual interests.

  • Aims: Recent research has suggested that for some individuals, educational studying may become compulsive and excessive and lead to ‘study addiction’. The present study conceptualized and assessed study addiction within the framework of workaholism, defining it as compulsive over-involvement in studying that interferes with functioning in other domains and that is detrimental for individuals and/or their environment. Methods: The Bergen Study Addiction Scale (BStAS) was tested — reflecting seven core addiction symptoms (salience, mood modification, tolerance, withdrawal, conflict, relapse, and problems) — related to studying. The scale was administered via a cross-sectional survey distributed to Norwegian (n = 218) and Polish (n = 993) students with additional questions concerning demographic variables, study-related variables, health, and personality. Results: A one-factor solution had acceptable fit with the data in both samples and the scale demonstrated good reliability. Scores on BStAS converged with scores on learning engagement. Study addiction (BStAS) was significantly related to specific aspects of studying (longer learning time, lower academic performance), personality traits (higher neuroticism and conscientiousness, lower extroversion), and negative health-related factors (impaired general health, decreased quality of life and sleep quality, higher perceived stress). Conclusions: It is concluded that BStAS has good psychometric properties, making it a promising tool in the assessment of study addiction. Study addiction is related in predictable ways to personality and health variables, as predicted from contemporary workaholism theory and research.

  • Background and aims: ‘Study addiction’ has recently been conceptualized as a behavioral addiction and defined within the framework of work addiction.  Using a newly developed measure to assess this construct, the Bergen Study Addiction Scale (BStAS), the present study examined the one-year stability of study addiction and factors related to changes in this construct over time, and is the first longitudinal investigation of study addiction thus far. Methods: The BStAS and the Ten Item Personality Inventory (TIPI) were administered online together with questions concerning demographics and study-related variables in two waves. In Wave 1, a total of 2,559 students in Norway and 2,177 students in Poland participated. A year later, in Wave 2, 1,133 Norwegians and 794 Polish who were still students completed the survey. Results: The test-retest reliability coefficients for the BStAS revealed that the scores were relatively stable over time. In Norway scores on the BStAS were higher in Wave 2 than in Wave 1, while in Poland the reverse pattern was observed. Learning time outside classes at Wave 1 was positively related to escalation of study addiction symptoms over time in both samples. Being female and scoring higher on neuroticism were related to an increase in study addiction in the Norwegian sample only. Conclusion: Study addiction appears to be temporally stable, and the amount of learning time spent outside classes predicts changes in study addiction one year later.

To pee or not to pee? Another look at paraphilic behaviours

Strange, bizarre and unusual human sexual behaviour is a topic that fascinates many people (including myself of course). Last week I got a fair bit of international media coverage being interviewed about the allegations that Donald Trump hired women to perform ‘golden showers’ in front of him (i.e., watching someone urinate for sexual pleasure, typically referred to as urophilia). I was interviewed by the Daily Mirror (and many stories used my quotes in this particular story for other stories elsewhere). I was also commissioned to write an article on the topic for the International Business Times (and on which this blog is primarily based). The IBT wanted me to write an article on whether having a liking for strange and/or bizarre sexual preferences makes that individual more generally deviant.


Although the general public may view many of these behaviours as sexual perversions, those of us that study these behaviours prefer to call them paraphilias (from the Greek “beyond usual or typical love”). Regular readers of my blog will know I’ve written hundreds of articles on this topic. For those of you who have no idea what parahilias really are, they are uncommon types of sexual expression that may appear bizarre and/or socially unacceptable, and represent the extreme end of the sexual continuum. They are typically accompanied by intense sexual arousal to unconventional or non-sexual stimuli. Most adults are aware of paraphilic behaviour where individuals derive sexual pleasure and arousal from sex with children (paedophilia), the giving and/or receiving of pain (sadomasochism), dressing in the clothes of the opposite sex (transvestism), sex with animals (zoophilia), and sex with dead people (necrophilia).

However, there are literally hundreds of paraphilias that are not so well known or researched including sexual arousal from amputees (acrotomophilia), the desire to be an amputee (apotemnophilia), flatulence (eproctophilia), rubbing one’s genitals against another person without their consent (frotteurism), urine (urophilia), faeces (coprophilia), pretending to be a baby (infantilism), tight spaces (claustrophilia), restricted oxygen supply (hypoxyphilia), trees (dendrophilia), vomit (emetophilia), enemas (klismaphilia), sleep (somnophilia), statues (agalmatophilia), and food (sitophilia). [I’ve covered all of these (and more) in my blog so just click on the hyperlinks of you want to know more about the ones I’ve mentioned in this paragraph].

It is thought that paraphilias are rare and affect only a very small percentage of adults. It has been difficult for researchers to estimate the proportion of the population that experience unusual sexual behaviours because much of the scientific literature is based on case studies. However, there is general agreement among the psychiatric community that almost all paraphilias are male dominated (with at least 90% of all those affected being men).

One of the most asked questions in this field is the extent to which engaging in unusual sex acts is deviant? Psychologists and psychiatrists differentiate between paraphilias and paraphilic disorders. Most individuals with paraphilic interests are normal people with absolutely no mental health issues whatsoever. I personally believe that there is nothing wrong with any paraphilic act involving non-normative sex between two or more consenting adults. Those with paraphilic disorders are individuals where their sexual preferences cause the person distress or whose sexual behaviour results in personal harm, or risk of harm, to others. In short, unusual sexual behaviour by itself does not necessarily justify or require treatment.

The element of coercion is another key distinguishing characteristic of paraphilias. Some paraphilias (e.g., sadism, masochism, fetishism, hypoxyphilia, urophilia, coprophilia, klismaphilia) are engaged in alone, or include consensual adults who participate in, observe, or tolerate the particular paraphilic behaviour. These atypical non-coercive behaviours are considered by many psychiatrists to be relatively benign or harmless because there is no violation of anyone’s rights. Atypical coercive paraphilic behaviours are considered much more serious and almost always require treatment (e.g., paedophilia, exhibitionism [exposing one’s genitals to another person without their consent], frotteurism, necrophilia, zoophilia).

For me, informed consent between two or more adults is also critical and is where I draw the line between acceptable and unacceptable. This is why I would class sexual acts with children, animals, and dead people as morally and legally unacceptable. However, I would also class consensual sexual acts between adults that involve criminal activity as unacceptable. For instance, Armin Meiwes, the so-called ‘Rotenburg Cannibal’ gained worldwide notoriety for killing and eating a fellow German male victim (Bernd Jürgen Brande). Brande’s ultimate sexual desire was to be eaten (known as vorarephilia). Here was a case of a highly unusual sexual behaviour where there were two consenting adults but involved the killing of one human being by another.

Because paraphilias typically offer pleasure, many individuals affected do not seek psychological or psychiatric treatment as they live happily with their sexual preference. In short, there is little scientific evidence that unusual sexual behaviour makes you more deviant generally.

Higher and higher: Can psychoactive substance use enhance creativity?

In a previous blog I examined whether celebrities are more prone to addictions. In that article I argued that many high profile celebrities have the financial means to afford a drug habit like cocaine or heroin. For many in the entertainment business such as being the lead singer in a famous rock band, taking drugs may also be viewed as one of the defining behaviours of the stereotypical ‘rock ‘n’ roll’ lifestyle. In short, it’s almost expected. There is also another way of looking at the relationship between celebrities and drugs and this is in relation to creativity, particularly as to whether the use of drugs can inspire creative writing or music. For instance, did drugs like cannabis and LSD help The Beatles create some of the best music ever such as Revolver? Did the Beach BoysBrian Wilson’s use of drugs play a major role in why the album Pet Sounds is often voted the best album of all time? Did the use of opium by Edgar Allen Poe create great fiction? Did William S. Burroughs’ use of heroin enhance his novel writing?


To investigate the question of whether drug use enhances creativity, I and my research colleagues Fruzsina Iszáj and Zsolt Demetrovics have just published a review paper in the International Journal of Mental Health and Addiction examining this issue. We carried out a systematic review of the psychological literature and reviewed any study that provided empirical data on the relationship between psychoactive substance use and creativity/artistic creative process that had been published in English in peer-reviewed journals or scientific books. Following a rigorous filtering process, we were surprised to find only 19 studies that had empirically examined the relationship between drug use and creativity (14 empirical studies and five case studies).

Six of the 19 studies (four empirical papers and two case reports) were published during the 1960s and 1970s. However, following the peak of psychedelia, only three papers (all of them empirical) were published in the following 20 years. Since 2003, a further 10 studies were published (seven empirical papers and three case studies). The majority of the studies (58%) were published in the USA. This dominance is especially true for the early studies in which six of the seven empirical papers and both case studies that were published before mid-1990s were written by US researchers. However, over the past 14 years, this has changed. The seven empirical papers published post-2000 were shared between six different countries (USA, UK, Italy, Wales, Hungary, Austria), and the three case studies came from three countries (USA, UK, Germany).

Seven empirical papers and two case studies dealt with the relationship between various psychoactive substances and artistic creation/creativity. Among the studies that examined a specific substance, six (three empirical papers and three case studies) focused on the effects of either LSD or psilocybin. One empirical study focused on cannabis, and one concerned ayahuasca.

With the exception of one study where the sample focused on adolescents, all the studies comprised adults. More non-clinical samples (15 studies, including case studies) were found than clinical ones (four studies). Three different methodological approaches were identified. Among the empirical studies, seven used questionnaires comprising psychological assessment measures such as the Torrance Test of Creative Thinking (TTCT).

According to the types of psychoactive substance effect on creativity, we identified three groups. These were studies that examined the effect of psychedelic substances (n=5), the effect of cannabis (n=1), and those that did not make a distinction between substances used because of the diverse substances used by participants in the samples (n=7). In one study, the substances studied were not explicitly identified.

The most notable observation of our review was that the findings of these studies show only limited convergence. The main reason for this is likely to be found in the extreme heterogeneity concerning the objectives, methodology, samples, applied measures, and psychoactive substances examined among the small number of studies. Consequently, it is hard to draw a clear conclusion about the effect of psychoactive substance use on creativity based on the reviewed material.

Despite the limited agreement, most of the studies confirmed some sort of association between creativity and psychoactive substance use, but the nature of this relationship was not clearly established. The frequently discussed view that the use of psychoactive substances leads to enhanced creativity was by no means confirmed. What the review of relevant studies suggests is that: (i) substance use is more characteristic in those with higher creativity than in other populations, and (ii) it is probable that this association is based on the inter-relationship of these two phenomena. At the same time, it is probable that there is no evidence of a direct contribution of psychoactive substances to enhanced creativity of artists.

It is more likely that substances act indirectly by enhancing experiences and sensitivity, and loosening conscious processes that might have an influence on the creative process. This means the artist will not be more creative but the quality of the artistic product will be altered due to substance use. On the other hand, it appears that psychoactive substances may have another role concerning artists, namely that they stabilize and/or compensate a more unstable functioning.

Beyond the artistic product, we also noted that (iii) specific functions associated with creativity appear to be modified and enhanced in the case of ordinary individuals due to psychoactive substance use. However, it needs to be emphasized that these studies examined specific functions while creativity is a complex process. In light of these studies, it is clear that psychoactive substances might contribute to a change of aesthetic experience, or enhanced creative problem solving. One study (a case study of the cartoonist Robert Crumb) showed that LSD changed his cartoon illustrating style. Similarly, a case study of Brian Wilson argued that the modification of musical style was connected to substance use. However, these changes in themselves will not result in creative production (although they may contribute to the change of production style or to the modification of certain aspects of pieces of arts). What was also shown is that (iv) in certain cases, substances may strengthen already existing personality traits.

In connection with the findings reviewed, one should not overlook that studies focused on two basically different areas of creative processes. Some studies examined the actual effects of a psychoactive substance or substances in a controlled setting, while others examined the association between creativity and chronic substance users. These two facets differ fundamentally. While the former might explain the acute changes in specific functions, the latter may highlight the role of chronic substance use and artistic production.

It should also be noted that the studies we reviewed differed not only regarding their objectives and methodology, but also showed great heterogeneity in quality. Basic methodological problems were identified in many of these studies (small sample sizes, unrepresentative samples, reliance on self-report and/or non-standardized assessment methods, speculative research questions, etc.). Furthermore, the total number of empirical studies was very few. At the same time, the topic is highly relevant both in order to understand the high level of substance use in artists and in order to clarify the validity of the association present in public opinion. However, it is important that future studies put specific emphasis on adequate methodology and clear research questions.

Dying for it: Bizarre autoerotic deaths (Part 2)

In my previous blog I examined some of the most bizarre autoerotic deaths reported in the medical forensic literature. Here are another five.

Case 1: Autoerotic death by aerosol propellant

Source: Medicine, Science and the Law. Personal details:  32-year old white US man. Single. Computer programmer.

  • Bizarre death event: Found dead in bed with cassette recorder next to him. He was wearing headphones which playing “snorting” horse sounds. There was also a can of aerosol propellant. At the end of the bed was a large painting of a male strapped to the hind legs of a horse who was being anally penetrating by the horse. The horse was ridden by a leather-clad woman. He was also wearing some kind if homemade masturbatory device. His death was recorded as cardio-respiratory failure consistent with aerosol propellant abuse (death by misadventure). Self-administration of the chemical agent to modify the sensations of masturbation. He was covered in dry semen stains.

Case 2: Autoerotic death by clothing

Source: Medicine, Science and the Law. Personal details:  25-year old Japanese male. Single.

  • Bizarre death event: Man found dead in his bed one morning. naked except for clothing wrapping his head and underpants which were pulled down. He was covered in dry semen stains. He had put a black skirt on his face and then pulled a second skirt upside down over his head and turned down the bottom of it. He then put a plastic bag over these two garments followed by a pair of tights. The legs of the tights were used to tie a knot around the bottom of the skirts. He then wrapped a third skirt around all of this. Death was due to suffocation.

Case 3: Autoerotic death by hanging (female)

Source: Handbook of Forensic Pathology. Personal details:  19-year old white female. Single. College student.

  • Bizarre death event: Woman was found dead in her bedroom hanging from the hinge of her closet door dressed as an Oriental “harem girl”. A window sash cord was tied around her body in a complicated fashion and she was also wearing a blindfold and mouth gag (made from the belt of her dressing gown). Next to her lay an underground magazine (this was folded out and showed a bizarre dance involving a clock – the minute hand being a nude male who would make love with the other figure on the hour), a paperback Hitchcock book which explained her fantasy. The paperback contained the story about an Oriental harem master. In this story the harem master provides girls to his lord who stored them by hanging them around his walls on hooks


Case 4: Autoerotic death by vacuum cleaner

Source: American Journal of Forensic Medicine and Pathology. Personal details: 57-year old white US male. Single. History of heart disease and chronic pancreatitis

  • Bizarre death event: Man was found naked slumped over his vacuum cleaner after a neighbour wondered why the vacuum cleaner had been on continuously for a long time. The man was found leaning against the dining table with his testicles, buttocks and thighs tightly bound with women’s tights. Near the table was a jar of urine, jars of lubricant and a wooden table leg covered in fecal excrement. The man was covered in burns from the vacuum cleaner. No defect was found in the vacuum cleaner. The man basically had a heart attack while engaged in autoerotic activity. The wooden table leg had been used in an attempt to stimulate orgasm via anal penetration. His wife had caught him masturbating with the vacuum cleaner before (they hadn’t had sex for five years). The death was classed as natural rather than accidental.

Case 5: Autoerotic death by hydraulic tractor shovel

Source: Journal of Forensic Sciences. Personal details:  62 year-old US white male. Married. Farmer.

  • Bizarre death event: Found dead in a barn lying on his front pinned under the hydraulic shovel of his tractor. His body was covered with semen stains and there was evidence of masochistic sexual bondage. His clothes were folded neatly away nearby. He was found naked except for a pair of women’s red shoes (with 8 inch heels), knee high stockings and tape duct wrapped around his ankles. Ropes led from his feet to the tractor which when raised would lift his inverted body causing complete suspension. It is not known exactly what happened but it is likely that the engine stalled and he was crushed underneath the tractor shovel. He died of positional asphyxiation by chest compression. This was an atypical autoerotic fatality because he did not purposely use asphyxiation but it did cause his death.

Dying for it: Bizarre autoerotic deaths (Part 1)

In previous blogs I have examined many different sexual paraphilias that have ended up in death for individuals engaged in such practices. Many of these are from autoerotic asphyxiation but also from other sexual practices such as electrophilia and anaesthesiophilia. Today’s blog takes a brief look at some of the most bizarre autoerotic deaths reported in the medical forensic literature.

Case 1: Autoerotic death by car

Source: Journal of Forensic Sciences. Personal details: 40-year old white US male airline pilot. Married and father of two children.

  • Bizarre death event: A man left his home at 6am in the morning and told his wife that he was going shooting in the country. He was found naked except for a large-link 10-foot chain harness secured around his body. (The harness was tied around the man’s neck in a moderately tight loop and bolted. The chain then went down his chest and was tied into another loop around his waist. This was tied to the bumper of the car) at 7.30am in the morning in a remote area crushed against the left fender of his car (equivalent of a VW beetle). The engine was still running, ignition was on and the driver’s door was still open. The steering wheel was tied so that it would go round in anti-clockwise circles. His clothes were in the boot of the car. Reconstruction of the events leading to his death showed that he was either being dragged round by the car or following the car producing feelings of asphyxia. When he had finished his sexual turn-on he had tried to approach the car door but had forgotten to undo the chain from the bumper. The chain had got tangled up in the car’s axle and the man was found strangled to death by the chain.

Case 2: Autoerotic death by hanging (male)

Source: American Journal of Forensic Medicine and Pathology. Personal details: 57-year old white US male. Single.

  • Bizarre death event: Early one winter’s morning, two joggers found a partially clothed man hanging from a tree five inches from the ground. He was hanging from a rope tied round his neck but also had two other loops of rope harness around his thighs which also encircled his chest. His neatly folded clothes lay two feet away along with lipstick and a jar of Vaseline. He was wearing a woman’s brown wig and a stuffed white bra. He also wore a pair of men’s red underpants, a pair of tights and a pair of high-heeled women’s shoes. He was also found to have a carrot protruding from his anus. Basically his seat harness slipped and he asphyxiated himself on the ropes.


Case 3: Autoerotic death by blankets

Source: American Journal of Forensic Medicine and Pathology. Personal details: 60-year old white US male. Single. Diagnosed schizophrenic and had various sexual compulsions. Well educated former teacher.

  • Bizarre death event: After being reported missing from work by his employer, a man was found dead rolled up in 14 different blankets which had been sewn together (the two outermost layers were found fixed with adhesive tape in various places which raised the possibility of murder). Inside the blankets he was dressed in two pairs of hotpants, a pair of long johns and a vest. The body was wet and his hands and arms were outstretched above his head. They found a plastic bag over his penis into which he had ejaculated. He was masturbating while inside the blankets but he had become too hypoxic and died. He was immobilized inside the blankets and was unable to free himself. Over the last few years he had bought an astonishing number of blankets by mail order (over 60 found in his apartment most of which seemed to have some ritual or obsessive meaning by the way were laid out. No pornography was found in the place.

Case 4: Autoerotic death by dental anaesthetic

Source: American Journal of Forensic Medicine and Pathology. Personal details: 59-year old white US male. Single. Antiques dealer

  • Bizarre death event: Found dead in his locked apartment. He was seated in front of a dental anaesthetic machine with the anaesthetic face-mask over his face. He was sucking on a rubber teat similar (but much bigger) than a baby’s feeding bottle. There were other anaesthetic machines around the apartment as well as a lot of sexual literature (magazines, photographs, paintings, manuscripts all concerned with his elaborate fetish some of which included photographs of himself in these situations). He was wearing a rubber type apron, three woollen cardigans, a woman’s blouse and two pairs of women’s trousers and a pair of women’s bloomers.

Case 5: Autoerotic death by electrocution

Source: Medicine, Science and the Law. Personal details: 36-year old UK male. Gay (with partner). Unemployed ex-television engineer

  • Bizarre death event: Man found dead with a wire cradle applied to his scrotum with another loop of wire (end folded over) inserted into his Vaseline-lubricated anus. The wires were connected to the two terminals that supplied the loudspeaker within the television. When switched on, these wires carried a current of 0.6 amps at 2.2 volts (a quarter of the current needed to light a small torch). The body had two significant injuries. One on the right side of his face (entrance mark of the current), and the other over the left side of his scrotum (where the loop of the wire had been). Unfortunately, one of the wires had broken off resulting in a cessation of the stimulating activity. The man looked inside the back of the open TV set and his face came into contact with an exposed metal cap which zapped 2500 volts through him. The metal cap was the only live part of the television set and it was this that killed him.

Bog standard: A brief look at toilet tissue eating

In previous blogs I have looked at pica (i.e., the eating of non-nutritive items or substances) and subtypes of pica such as geophagia (eating of soil, mud, clay, etc.), pagophagia (eating of ice), acuphagia (eating of metal), and coprophagia (eating of faeces). It wasn’t until I started to research on specific sub-types of pica, that I discovered how many different types of non-food substances had been identified in the academic and clinical literature. For instance, Dr. V.J. Louw and colleagues provided a long list in a 2007 issue of the South African Medical Journal including cravings for the heads of burnt matches (cautopyreiophagia), cigarettes and cigarette ashes, paper, starch (amylophagia), crayons, cardboard, stones (lithophagia), mothballs, hair (trichophagia), egg shells, foam rubber, aspirin, coins, vinyl gloves, popcorn (arabositophagia), and baking powder. Most of these are generally thought to be harmless but as Louw and colleagues note, a wide range of medical problems have been documented:

“These include abdominal problems (sometimes necessitating surgery), hypokalaemia, hyperkalaemia, dental injury, napthalene poisoning (in pica for toilet air-freshener blocks), phosphorus poisoning (in pica for burnt matches), peritoneal mesothelioma (geophagia of asbestos-rich soil), mercury poisoning (in paper pica), lead poisoning (in dried paint pica and geophagia), and a pre-eclampsia-like syndrome (baking powder pica)”.

In the clinical literature, the eating of paper has been occasionally documented (although anecdotal evidence suggests this is fairly common and I remember doing it myself as a child). A review paper on pica by Dr. Silvestre Frenk and colleagues in the Mexican journal Boletín Médico del Hospital Infantil de México highlighted dozens of pica-subtypes and created many new names for various pica sub-types. They proposed that people who eat paper display ‘papirophagia’ (in fact if you type ‘papirphagia’ into Google, you only get one hit – the paper by Silvestre and colleagues – although this blog may make it two!). Eating paper is not thought to be particularly harmful although I did find a case of mercury poisoning because of ‘paper pica’ (as the authors – Dr. F. Olynk and Dr. D. Sharpe – called it) in a 1982 issue of the New England Journal of Medicine.


One sub-type of papirophagia is the eating of toilet paper. As far as I am aware, there is only one case study in the literature and this was published back in 1981, Dr. J. Chisholm Jr. and Dr. H. Martín in the Journal of the National Medical Association. They described the case of a 37-year old black woman with an “unusually bizarre craving” for toilet tissue paper. The authors reported that:

“[The] woman was referred for evaluation of disturbed smell and loss of taste for over one year. These were associated with chronic fatigue and listlessness. During this same period of time, she rather embarrassedly admitted to an overwhelming desire to eat toilet tissue. Frequently, she would awaken at night and dash to her bathroom to eat toilet tissue. No other type(s) of pica were admitted. In addition, she gave a long history of menorrhagia and frequently passed vaginal blood clots during her menses. Her libido was normal and there was no history of poor wound healing, skin or mucous membrane lesions, or intestinal symptoms. Her dietary history suggested a high carbohydrate diet, and due to a mild exogenous obesity she intermittently resorted to a vegan-like diet that included beans and various seeds”

A variety of medical tests were carried out and she was diagnosed with combined iron and zinc deficiency. She was treated with iron and zinc tablets and within a week, both her taste and smell had returned, and her energy levels greatly improved. Zinc deficiencies can lead to a wide variety of clinical disorders including loss of small and taste, anorexia, dwarfism (i.e., growth retardation), impaired wound healing, and geophagia. The woman’s (sometimes) vegan diet may have been to blame for her zinc deficiency as the authors noted that:

Although vegetables contain zinc, vegans should be made aware that zinc from plant sources is not readily absorbed because naturally occurring phytates, particularly high in beans and seeds, reduce zinc gastrointestinal absorption. Carbohydrates are very poor sources of zinc. Chronic iron deficiency secondary to chronic menorrhagia accounts well for the anemia, fatigue, and unusual pica for toilet tissue noted in this patient”.

Paper pica has occasionally been mentioned in other academic papers although details have typically been limited. For instance, a 1995 paper in the journal Birth by Dr. N.R. Cooksey on three cases of pica in pregnancy reported that one of the women chewed non-perfumed blue toilet paper during the first trimester of her pregnancy (and was forced by her mother to stop). There was also a 2003 paper published by Dr. Dumaguing in the Journal of Geriatric Psychiatry and Neurology examining pica in mentally ill geriatrics. One of the cases mentioned was a 76-year old patient that not only ingested their medication (an emollient cream for arthritis) but was also recorded eating toilet paper, napkins, Styrofoam cups, crayons, and other patients’ medications.

A more recent 2008 paper by Dr. Sera Young and her colleagues in the journal PLoS ONE, critically reviewed procedures and guidelines for interviews and sample collection in relation to pica substances. In describing the protocols involved, they referred to paper pica in the questions that should be asked:

“What is the local name, brand name, or type of pica substance desired or consumed? This will help others to know if this substance has already been studied and assist interested researchers in obtaining subsequent samples at a later date. Furthermore, different manufactured products may contain different materials, e.g. Crayola chalkboard chalk contains slightly different ingredients from other brands. Similarly, the consequences of toilet tissue paper consumption are different from those of eating pages of a novel; information would be lost if the substance was simply described as paper. For these reasons, the substance consumed should be described in as much detail and as accurately as possible”.

Personally (and based on anecdotal evidence), I think that papirophagia is not overly rare (especially among children – although I admit this may be more out of curiosity that craving) but the clinical literature suggests that it is a fairly rare disorder found amongst distinct sub-groups (pregnant women, the mentally ill). Given the fact that for most people eating paper would not cause any problems, this would provide the main reason why so few cases end up seeking medical, clinical, and/or psychological help.
