World of the Weird: The A-Z of strange and bizarre addictions
Today’s blog takes a brief look at some of the stranger addictions that have been written about in the academic literature (or academics that have tried to argue these behaviours can be addictive). Some of these ‘addictions’ listed are not addictions by my own criteria but others have argued they are. The papers or books that have argued the case for the cited behaviour being a type of addiction are found in the ‘Further reading’ section.
- Argentine tango addiction: A French study published in a 2013 issue of the Journal of Behavioral Addictions by Remi Targhetta and colleagues argued that a minority of 1129 Argentine tango dancers they surveyed may be addicted to dancing. In 2015, I and some of my Hungarian colleagues developed the Dance Addiction Inventory (published in PLoS ONE) and also argued that a minority of dancers (more generally) might be addicted to dance and conceptualized the behaviour as a form of exercise addiction.
- Badminton addiction: While there are many behaviours I could have chosen here including addictions to box set television watching (aka ‘box set bingeing), bargain hunting, bungee jumping, blogging, and bodybuilding, a recent 2018 paper published in NeuroQuantology by Minji Kwon and colleagues carried out a neuroimaging study on a sample 45 badminton players. Using the Korean Exercise Addiction Scale, 20% of the sample were defined as being addicted to badminton.
- Carrot eating addiction: Again, there are many behaviours I could have chosen here including alleged addictions to crypto-trading, chaos, collecting, crosswords, and cycling, there are a number of published case studies in the psychological literature highlighting individuals addicted to eating carrots including papers by Ludek Černý and Karel Černý, K. (British Journal of Addiction, 1992), and Robert Kaplan (Australian and New Zealand Journal of Psychiatry, 1996).
- Death addiction: A recent paper by Dr. Marc Reisinger entitled ‘Addiction to death’ in the journal CNS Spectrums attempted to argue that attraction to death be considered an addiction similar to gambling addiction. Reisinger related the concept to individuals who have left Europe to join the jihad in Syria, and outlined the case of 24-year-old French-Algerian Mohamed Merah who committed several attacks in Toulouse in 2012 and who ‘glorified’ death. Te paper claimed that this “addiction to death is taught by Salafist preachers, whose videos, readily accessible on the internet, are kind of advertisements for death, complete with depictions of soothing fountains and beautiful young girls”.
- Entrepreneurship addiction: There are a couple of papers by April Spivack and Alexander McKelvie (a 2014 paper in the Journal of Business Venturing, and a 2018 paper Academy of Management) arguing that entrepreneurship can be addictive. They define ‘entrepreneurship addiction’ as “the excessive or compulsive engagement in entrepreneurial activities that results in a variety of social, emotional, and/or physiological problems and that despite the development of these problems, the entrepreneur is unable to resist the compulsion to engage in entrepreneurial activities”. They also make the case that that entrepreneurship addiction is different from workaholism.
- Fortune telling addiction: Although I could have included addictions to financial trading or fame, a 2015 paper in the Journal of Behavioral Addictions by Marie Grall-Bronnec and her colleagues reported the case study of a woman (Helen) that was ‘addicted’ to fortune tellers. They used my addiction criteria to assess whether Helen was addicted to fortune telling, and argued that she was.
- Google Glass addiction: In previous blogs I have written on addictions to gossip and gardening (although these were based more on non-academic literature). However, a 2015 paper published by Kathryn Yung and her colleagues in the journal Addictive Behaviors, published the first (and to my knowledge) only case of addiction to Google Glass (wearable computer-aided glasses with Bluetooth connectivity to internet-ready devices. The authors claimed that their paper, (i) showed that excessive and problematic uses of Google Glasscan be associated with involuntary movements to the temple area and short-term memory problems, and (ii) highlighted that the man in their case study displayed frustration and irritability that were related to withdrawal symptoms from excessive use of Google Glass.
- Hacking addiction: Back in the late 1990s and early 2000s I wrote a number of papers on internet addiction and included ‘hacking addiction’ as a type of internet addiction. Given the criminal element of this type of internet addiction I wrote about it in criminological-based journals such as The Probation Journal (1997) and The Police Journal (2000). One of the most infamous cases that I have written about took place in London in 1993, where Paul Bedworth was accused of hacking-related crime causing over £500,000 worth of damage. On the basis of expert witness testimony, he was acquitted on the basis that he was addicted to hacking. Since then, various papers have been published arguing that hacking can be an addiction. For instance, in an in-depth interview study of 62 hackers, Siew Chan and Lee Yao used addiction as a framework to explain their participants’ behaviour (see their paper in the Review of Business Information Systems, 2005).
- Internet search addiction: Although I was tempted to go for IVF addiction, I thought I would go for ‘internet search addiction’ which basically refers to constant ‘googling’ where individuals spend hours and hours every day using online databases to go searching for things. This behaviour was first alluded to by Kimberley Young in her 1999 classification of different types of internet addiction which she called ‘information overload’ and was defined as compulsive web surfing or database searches. More recently, Yifan Wang and her colleagues developed the Questionnaire on Internet Search Dependence (QISD) published in Frontiers in Public Health (FiPH). I criticized the QISD in a response paper published in FiPH, not because I didn’t think internet search addiction didn’t exist (because theoretically it might do, even though I’ve never come across a genuine case) but because the items in the instrument had very little to do with addiction.
- Joyriding addiction: There have been a number of academic papers published on joyriding addiction. Arguably the most well-known study was published by Sue Kellett and Harriet Gross in a 2006 issue of Psychology, Crime and Law. The study comprised semi-structured interviews with 54 joyriders (aged 15 to 21 years of age) all of whom were convicted car thieves (“mainly in custodial care”). The results of the study indicated that all addiction criteria occurred within the joyriders’ accounts of their behaviour particularly ‘‘persistence despite knowledge and concern about the harmful consequences’’, ‘‘tolerance’’, ‘‘persistent desire and/or unsuccessful attempts to stop’’, “large amounts of time being spent thinking about and/or recovering from the behaviour’’ and “loss of control”. The paper also cited examples of ‘withdrawal’ symptoms when not joyriding, the giving up of other important activities so that they could go joyriding instead, and spending more time participating in joyriding than they had originally intended.
- Killing addiction: The idea of serial killing being conceptualized as an addiction in popular culture is not new. For instance, Brian Masters book about British serial killer Dennis Nilsen (who killed at least 12 young men) was entitled Killing for Company: The Story of a Man Addicted to Murder, and Mikaela Sitford’s book about Harold Shipman, the British GP who killed over 200 people, was entitled Addicted to Murder: The True Story of Dr. Harold Shipman. In Eric Hickey’s 2010 book Serial Murderers and Their Victims, Hickey makes reference to an unpublished 1990 monograph by Dr. Victor Cline who outlined a four-factor addiction syndrome in relation to sexual serial killers who (so-called ‘lust murderers’ that I examined in a previous blog). One of the things that I have always argued throughout my career, is that someone cannot become addicted to an activity or a substance unless they are constantly being rewarded (either by continual positive and/or negative reinforcement). Given that serial killing is a discontinuous activity (i.e., it happens relatively infrequently rather than every hour or day) how could killing be an addiction? One answer is that the act of killing is part of the wider behaviour in that the preoccupation with killing can also include the re-enacting of past kills and the keeping of ‘trophies’ from the victims (which I overviewed in a previous blog).
- Love addiction: In the psychological literature, the concept of love addiction has been around for some time dating back to works by Sigmund Freud. Arguably the most cited work in this area is the 1975 book Love and Addiction by Stanton Peele and Archie Brodsky. Their book suggested that some forms of love are actually forms of addiction, and tried to make the case that some forms of love addiction may be potentially more destructive and prevalent than widely recognized opiate drugs. There have also been a number of instruments developed assessing love addiction including the Love Addiction Scale (developed by Hunter, Nitschke, and Hogan, 1981), and the Passionate Love Scale (developed by Hatfield, and Sprecher, 1986).
- Muscle dysmporphia as an addiction: In a paper I published with Andrew Foster and Gillian Shorter in a 2015 issue of the Journal of Behavioral Addictions, we argued that muscle dysmorphia (MD) could be classed as an addiction. MD is a condition characterised by a misconstrued body image in 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 body dysmorphic disorder, an eating disorder, and/or part of the obsessive-compulsive disorder symptomatology. Reviewing the most salient literature on MD, we proposed an alternative classification of MD that we termed the ‘Addiction to Body Image’ (ABI) model. We argued the addictive activity in MD is the maintaining of body image via a number of different activities such as bodybuilding, exercise, eating specific foods, taking specific drugs (e.g., anabolic steroids), shopping for specific foods, food supplements, and/or physical exercise accessories, etc.. 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). Based on empirical evidence, we proposed that MD could be re-classed as an addiction due to the individual continuing to engage in maintenance behaviours that may cause long-term harm.
- News addiction: Although I could have chosen nasal spray addiction or near death addiction, a recent 2017 paper on ‘news addiction’ was published in the Journal of the Dow University of Health Sciences Karachi by Ghulam Ishaq and colleagues. The authors used some of my papers on behavioural addiction to argue for the construct of ‘news addiction’ as a construct to be empirically investigated. The authors also developed their own 19-item News Addiction Scale (NAS) although the paper didn’t give any examples of any of the items in the NAS. In relation to personality types (and like other addictions), they found news addiction was positively correlated with neuroticism and negatively correlated with conscientiousness. Given that this is the only study on news addiction that I am aware of, I’ll need a lot more research evidence before I am convinced that it really exists.
- Online auction addiction: A number of academics have made the claim that some individuals can become addicted to participating in online auctions. In a 2004 paper on internet addiction published in American Behavioral Scientist, Kimberley Young mentioned online auction [eBay] addiction in passing. The same observation was also made in a later 2009 paper by Tonino Cantelmi and Massimo Talls in the Journal of CyberTherapy and Rehabilitation. Other researchers have carried out empirical studies including a (i) 2007 paper by Cara Peters and Charles Bodkin in the Journal of Retailing and Consumer Services, (ii) 2008 paper by Chih-Chien Wang in the Proceedings of the Asia-Pacific Services Computing Conference, and (iii) 2011 study carried out by Dr. Ofir Turel and colleagues published in the MIS Quarerly. These papers indicated that those with problematic online auction use experienced (i) psychological distress, (ii) habitual usage, (iii) compulsive behaviour, (iv) negative consequences, and/or (v) dependence, withdrawal and self-regulation.
- Pinball addiction: Although I could have listed alleged addictions to plastic surgery and poetry, as far as I am aware, I am the only academic to have published a paper on pinball addiction. Back in 1992, I published a case study in Psychological Reports. My paper featured the case of a young man (aged 25 years) who (based on classic addiction criteria) was totally hooked on pinball. It was the most important thing in his life, used the behaviour to modify his moods, got withdrawal symptoms if he was unable to play pinball, had engaged in repeated efforts to cut down or stop playing pinball, and compromised all other activities in his life (education, occupation and relationships). To me, this individual had a gaming addiction but it was pinball rather than videogame addiction.
- Qat addiction: Qat (sometimes known as khat, kat, cat, and ghat) is a flowering plant traditionally used as a mild stimulant in African and Middle East countries (Somalia, Yemen, Ethiopia). Heavy qat users can experience many side effects including insomnia, anxiety, increased aggression, high blood pressure, and heart problems. There are numerous reports in the medical literature of qat addiction (see papers by Rita Manghi and colleagues in the Journal of Psychoactive Drugs, and Nezar Al-Hebshi and Nils Skuag in Addiction Biology).
- Rock climbing addiction: Over the past two years, a couple of papers by Robert Heirene, David Shearer, and Gareth Roderique-Davies have looked at the addictive properties of rock climbing specifically concentrating on withdrawal symptoms and craving. In the first paper on withdrawal symptoms published in 2016 in the Journal of Behavioral Addictions, the authors highlighted some previous research suggesting that there are similarities in the phenomenology of substance-related addictions and extreme sports (in this case rock climbing). The study concluded that based on self-report, rock climbers experienced genuine withdrawal symptoms during abstinence from climbing and that these were comparable to individuals with substance and other behavioural addictions. In a second investigation just published in Frontiers in Psychology, the same team reported the development of the Rock Climbing Craving Questionnaire comprising three factors (‘positive reinforcement’, ‘negative reinforcement’ and ‘urge to climb’).
- Study addiction: I was spoilt for choice on the letter ‘S’ and could have mentioned addictions to speeding, selfie-taking, shoplifting, Sudoko, and stock market speculation. However, there are now a number of published papers on ‘study addiction’ (individuals addicted to their academic study), three of which I have co-authored (all in the Journal of Behavioral Addictions and led by my colleague Pawel Atroszko). We have conceptualised study addiction as a type of work addiction (or a pre-cursor to work addiction) and in a series of studies (including longitudinal research) we have found empirical evidence of ‘study addiction’. Italian researchers (Yura Loscalzo and Marco Giannini) have also published research on ‘overstudying’ and ‘studyholism’ too (in the journals ARC Journal of Psychiatry, 2017; Social Indicators Research, 2018).
- Tanning addiction: There is now lots of empirical research examining ‘tanorexia’ (individuals who crave tanning and spend every day on sunbeds). However, I along with my colleagues in Norway recently reconceptualised tanorexia as a ‘tanning addiction’ and developed a scale to assess it (which was recently published in a 2018 issue of the British Journal of Dermatology). Our study was the largest over study on tanning (over 23,000 participants) and our newly developed scale (the Bergen Tanning Addiction Scale) had good psychometric properties.
- Upskirting addiction: Upskirting refers to taking a photograph (typically with a smartphone) up someone’s skirt without their permission. In the UK there have been a number of high profile court cases including Paul Appleby who managed to take 9000 upskirting photos in the space of just five weeks (suggesting that he was doing it all day every day to have taken so many photos), and Andrew MacRae who had amassed 49,000 upskirt photos and videos using hidden cameras at his workplace, on trains, and at the beach. Both men avoided a custodial sentence because their lawyers argued they were addicted and/or had a compulsion to upskirting. In a 2017 issue of the Law Gazette, forensic psychologist Julia Lam made countless references to upskirting in an overview of voyeuristic disorder. Dr. Lam also talked about her treatment of upskirting voyeurs and recounted one case which she claimed was a compulsion (and who was successfully treated). The case involved a male university student who was very sport active but who masturbated excessively whenever major sporting events or important exams were imminent as a coping strategy to relieve stress.
- Virtual reality addiction: Back in 1995, in a paper I entitled ‘Technological addictions’ in the journal Clinical Psychology Forum, I asserted that addiction to virtual reality would be something that psychologists would be seeing more of in the future. Although I wrote the paper over 20 years ago, there is still little empirical evidence (as yet) that individuals have become addicted to virtual reality (VR). However, that is probably more to do with the fact that – until very recently – there had been little in the way of affordable VR headsets. (I ought to just add that when I use the term ‘VR addiction’ what I am really talking about is addiction to the applications that can be utilized via VR hardware rather than the VR hardware itself). Of all the behaviours on this list, this is the one where there is less good evidence for its existence. Perhaps of most psychological concern is the use of VR in video gaming. There is a small minority of players out there who are already experiencing genuine addictions to online gaming. VR takes immersive gaming to the next level, and for those that use games as a method of coping and escape from the problems they have in the real world it’s not hard to see how a minority of individuals will prefer to spend a significant amount of their waking time in VR environments rather than their real life.
- Water addiction: In a blog I wrote back in 2015, I recounted some press stories on individuals who claimed they were ‘addicted’ to drinking water. My research into the topic led to a case study of ‘water dependence’ published a 1973 issue of the British Journal of Addiction by E.L. Edelstein. This paper reported that the excessive drinking of water can dilute electrolytes in an individual’s brain and cause intoxication. This led me to a condition called polydipsia (which in practical terms means drinking more than three litres of water a day) which often goes hand-in-hand with hyponatraemia (i.e., low sodium concentration in the blood) and in extreme cases can lead to excessive water drinkers slipping into a coma. There are also dozens and dozens of academic papers on psychogenic polydipsia (PPD). A paper by Dr. Brian Dundas and colleagues in a 2007 issue of Current Psychiatry Reports noted that PPD is a clinical syndrome characterized by polyuria (constantly going to the toilet) and polydipsia (constantly drinking too much water), and is common among individuals with psychiatric disorders. A 2000 study in European Psychiatry by E. Mercier-Guidez and G. Loas examined water intoxication in 353 French psychiatric inpatients. They reported that water intoxication can lead to irreversible brain damage and that around one-fifth of deaths among schizophrenics below the age of 53 years are caused this way. Whether ‘water intoxication’ is a symptom of being ‘addicted’ to water depends upon the definition of addiction being used.
- X-ray addiction: OK, this one’s a little bit of a cheat but what I really wanted to concentrate on what has been unofficially termed factitious disorder (FD). According to Kamil Jaghab and colleagues in a 2006 issue of the Psychiatry journal “FD is sometimes referred to as hospital addiction, pathomimia, or polysurgical addiction”. The primary characteristic of people suffering from FD is that they deliberately pretend to be ill in the absence of external incentives (such as criminal prosecution or financial gain). It is called a factitious because sufferers feign illness, pretend to have a disease, and/or fake psychological trauma typically to gain attention and/or sympathy from other people. Again, whether such behaviours can be viewed as an addiction depends upon the definition of addiction being used.
- YouTube addiction: I unexpectedly found my research on internet addiction being cited in a news article by Paula Gaita on compulsive viewing of YouTube videos (‘Does compulsive YouTube viewing qualify as addiction?‘). The article was actually reporting a case study from a different news article published by PBS NewsHour by science correspondent Lesley McClurg (‘After compulsively watching YouTube, teenage girl lands in rehab for digital addiction’). The story profiled a student whose obsessive viewing of YouTube content led to extreme behaviour changes and eventually, depression and a suicide attempt. Not long after this, I and my colleague Janarthanan Balakrishnan published what we believe is the only ever study on YouTube addiction in the Journal of Behavioral Addictions. In a study of over 400 YouTube users we found that YouTube addiction was more associated with content creation than watching content
- ‘Zedding’ addiction: OK, I’m using the Urban Dictionary’s synonym here as a way of including ‘sleep addiction’. The term ‘sleep addiction’ is sometimes used to describe the behavior of individuals who sleep too much. Conditions such as hypersomnia (the opposite of insomnia) has been referred to ‘sleeping addiction’ (in the populist literature at least). In a 2010 issue of the Rhode Island Medical Journal, Stanley Aronson wrote a short article entitled “Those esoteric, exoteric and fantabulous diagnoses” and listed clinomania as the compulsion to stay in bed. Given the use of the word ‘compulsive’ in this definition, there is an argument to consider clinomania as an addiction or at least a behaviour with addictive type elements.
