Fat’s life: Another look inside the world of feederism
Online letter from Jill to ‘Dr. Feeder’: “I am a feedee from Boston in desperate need of a feeder. I have tried dieting and I know my mission is to be fat. I feel I can’t do it alone. I fantasize about meeting a dominant man who is a Feeder…How do I get fat on my own? What foods? Can you give me a sample daily diet?”
Response to Jill’s letter from ‘Dr. Feeder’: “See my article ‘How To Get Fat‘. The kinds of foods don’t matter so much. Eat what you enjoy the most, especially if it’s fattening. The more you enjoy overeating, the more you will overeat. A lot of variety is also important”.
In a previous blog on fat fetishism, I noted that the fetish also included ‘feederism’ and ‘gaining’ in which sexual arousal and gratification is stimulated through the person (referred to as the ‘feedee’) gaining body fat. Feederism is a practice carried out by many fat admirers within the context of their sexual relationships and is where the individuals concerned obtain sexual gratification from the encouraging and gaining of body fat through excessive food eating. Sexual gratification may also be facilitated and/or enhanced the eating behaviour itself, and/or from the feedee becoming fatter – known as ‘gaining’ – where either one or both individuals in the sexual relationship participate in activities that result in the gaining of excess body fat.
Since writing my previous article on the topic, I have briefly written about feederism in two of my academic papers on sexual paraphilias (one in the Archives of Sexual Behavior in relation to a case study I wrote on fart fetishism, and the other in the Journal of Behavioral Addictions on how the internet has facilitated scientific research into paraphilias – see ‘Further reading’ below). However, I was also interviewed for the Discovery Channel’s television programme Forbidden about American Gabi Jones from Colorado (aka ‘Gaining Gabi’) who appeared in the episode ‘Pleasure and Pain’.
At the time when the television programme was being recorded, Gabi weighed 490 pounds and her sole aim was to get even fatter and heavier (before she became a feedee she was 250 pounds). It is also her career and her thousands of online fans pay money who pay $20 a month to watch her eat as well as sending her food to eat (you can check out her online website here, but pleased be warned that it contains explicit sexual content). She also claims that she becomes sexually aroused when eating excessively.
“When I indulge, I never rush. I take my time and treat all meals as very sexual experiences. I love being fat and the idea of getting large excites me…For as long as I remember, I always loved the idea of getting softer and being this piece of art that I am creating…My body is a work of art”.
She claims she does it to show that women can be empowered and that fat can be sexy. She’s also a campaigner for ‘fat acceptance’. However, the (US) National Association for the Advancement of Fat Acceptance (NAAFA) is anti-feederism. The NAAFA exists “to help build a society in which people of every size are accepted with dignity and equality in all aspects of life” but has specifically noted in its manifesto that:
“NAAFA supports an individual’s right to control all choices concerning his or her own body. NAAFA opposes the practice of feeders, in which one partner in a sexual relationship expects and encourages another partner to gain weight…That all bodies, of all sizes, are joyous and that individuals of all sizes can and should expect and demand respect from sexual partners for their bodies just as they are. That people of all sizes become empowered to demand respect for their bodies in the context of sexual relationships, without attempting to lose or gain weight in order to win a partner’s approval or attract or retain that partner’s desire”.
At the time she was interviewed, Gabi had two ‘feeders’ – one male (Kenyon, from Kansas, US) and one female (nicknamed ‘Hearts’, from Colorado). As the show’s production notes reported:
“Kenyon lives in a small town in Kansas…Gabi says that Kenyon has actually been a fan of hers since he was 12 or 13 [years old], he discovered her online. Gabi says that she wouldn’t have anything to do with him because he was not of age, but after [Kenyon’s 18th birthday she] accepted him into her life as her food slave. Kenyon says that he had fantasized for years about feeding her live in person…He is now totally devoted to Gabi and she is happy to have him as part of her ‘chosen family’ and hopes to move him out from Kansas to Colorado to live with her fulltime someday soon…Hearts makes sure that Gabi has all the food she could want and need. Gabi also feeds her. It’s not a sexual thing or anything – ‘we’re not lesbians, we’re just really close friends’ – but when they feed each other it’s ‘sexy and fun’. They met in college at the start of this year and haven’t left each other’s side since…Hearts is also gaining. Gabi got her into it one day when they were lying on her bed and Hearts noticed how soft Gabi’s tummy was. This made her decide she wanted to get fat too. Hearts is currently 201 pounds and her goal weight is 400 pounds…Gabi says there are two types of gainers – ‘feedees’ who’ll eat anything and ‘foodees’ who’ll eat only quality food, not junk. Gabi says she identifies more with a foodie”.
Academically, there have been an increasing number of papers published over the last few years. For instance, Dr. Lesley Terry and her colleagues have also published papers on feederism in the Archives of Sexual Behavior. The first was a case study (which I outlined in my previous blog), and more recently an interesting experiment that assessed individuals’ arousal to feederism compared to ‘normal’ sexual activity and neutral activity. A total of 30 volunteers (15 men and 15 women) were assessed using penile plethysmography (for the males) and vaginal photoplethysmography (for the females) – none of who were feeders or feedees. The paper reported that:
“The volunteers were all shown sexual, neutral, and feeding still images while listening to audio recordings of sexual, neutral, and feeding stories. Participants did not genitally respond to feeding stimuli. However, both men and women subjectively rated feeding stimuli as more sexually arousing than neutral stimuli…the results of this study provide limited, but suggestive, evidence that feederism may be an exaggeration of a more normative pattern of subjective sexual arousal in response to feeding stimuli that exists in the general population.
Dr. Ariane Prohaska has published papers on feederism in such journals as the International Journal of Social Science Studies and Deviant Behavior. In one of her studies, she carried out a content analysis of feederism-related websites and examining feederism within heterosexual relationships. She concluded that feederism websites can take many forms “such as groups, advice sites, personal ads, and pornography. The content analysis also revealed that the internet is a place where fat women can find a community of similar others to support them”. She also noted that although feedersim has been classified as a transgressive sexual behaviour, it “usually mimics patriarchal sex in the process”. She also claimed that at its extreme “feederism is an abusive behavior dangerous to the partner (usually the woman) who desires to gain weight as quickly as possible”. As highlighted in the case of Gabi above, Dr. Prohaska concludes that feederism is a communal behavior, but she also notes:
“[W]hen it comes to feederism, men are still in control of the behavior and of how women are portrayed and treated as feedees. Although some of the websites discussed here may be advancing transgressive ideas about fat women as sexual beings, the objectification of women as sex objects is further perpetuated by these same websites. Bodies matter; normative ideas about fat women and heterosexual sex offline are perpetuated online. The internet is patriarchal as offline society. At its extreme, ideas about control over women involve manipulating their bodies using dangerous means, and the lines between consent and sexual assault are blurred. Consent is a difficult term to define in a culture where patriarchal values about sex have been internalized by members of society. Still, the internet has the potential to create loving, supportive communities for people of size rather than exploitative communities that mimic the offline world”.

Myth world: Addictive personality does not exist
(Please note: This article is a slightly expanded and original version of an article that was first published in The Conversation).
“Life is a series of addictions and without them we die”. This is my favourite quote in the academic addiction literature and was made back in 1990 in the British Journal of Addiction by Professor Isaac Marks. This deliberately provocative and controversial statement was made to stimulate debate about whether excessive and potentially problematic activities such as gambling, sex and work can really be classed as genuine addictive behaviours. Many of us might say to ourselves that we are ‘addicted’ to tea or coffee, our work, or know others who we might describe as having addictions watching the television or using pornography. But is this really true?
The issue all comes down to how addiction is defined in the first place as many of us in the field disagree on what the core components of addiction are. Many would argue that the word ‘addiction’ or ‘addictive’ is used so much in everyday circumstances that word has become meaningless. For instance, saying that a book is an ‘addictive read’ or that a specific television series is ‘addictive viewing’ renders the word useless in a clinical setting. Here the word ‘addictive’ is arguably used in a positive way and as such it devalues the real meaning of the word.
The question I get asked most – particularly by the broadcast media – is what is the difference between a healthy excessive enthusiasm and an addiction and my response is simple – a healthy excessive enthusiasm adds to life whereas an addiction takes away from it. I also believe that to be classed as an addiction, any such behaviour should comprise a number of key components including overriding preoccupation with the behaviour, conflict with other activities and relationships, withdrawal symptoms when unable to engage in the activity, an increase in the behaviour over time (tolerance), and use of the behaviour to alter mood state. Other consequences such as feeling out of control with the behaviour and cravings for the behaviour are often present. If all these signs and symptoms are present I would call the behaviour a true addiction. However, that hasn’t stopped others accusing me of ‘watering down’ the concept of addiction.
A few years ago, Dr. Steve Sussman, Nadra Lisha and I published a large and comprehensive review in the journal Evaluation and the Health Professions examining the co-relationship between eleven different potentially addictive behaviours reported in the academic literature (smoking tobacco, drinking alcohol, taking illicit drugs, eating, gambling, internet use, love, sex, exercise, work, and shopping). We examined the data from 83 large-scale studies and reported an overall 12-month prevalence of an addiction among U.S. adults varies from 15% to 61%. We also reported it plausible that 47% of the U.S. adult population suffers from maladaptive signs of an addictive disorder over a 12-month period, and that it may be useful to think of addictions as due to problems of lifestyle as well as to person-level factors. In short – and with many caveats – our paper argued that at any one time almost half the US population are addicted to one or more behaviours.
There is a lot of scientific literature showing that having one addiction increases the propensity to have other co-occurring addictions. For instance, in my own research I have come across alcoholic pathological gamblers and we can all probably think of individuals that we might describe as caffeine-addicted workaholics. It is also very common for individuals that give up one addiction to replace it with another (which we psychologists call ‘reciprocity’). This is easily understandable as when an individual gives up one addiction it leaves a large hole in the waking lives (often referred to as the ‘void’) and often the only activities that can fill the void and give similar experiences are other potentially addictive behaviours. This has led many people to describe such people as having an ‘addictive personality’.
While there are many pre-disposing factors for addictive behaviour including genetic factors and psychological personality traits such as high neuroticism (anxious, unhappy, prone to negative emotions) and low conscientiousness (impulsive, careless, disorganised), I would argue that ‘addictive personality’ is a complete myth. Even though there is good scientific evidence that most people with addictions are highly neurotic, neuroticism in itself is not predictive of addiction (for instance, there are individuals who are highly neurotic but are not addicted to anything so neuroticism is not predictive of addiction). In short, there is no good evidence that there is a specific personality trait (or set of traits) that is predictive of addiction and addiction alone.
Doing something habitually or excessively does not necessarily make it problematic. While there are many behaviours such as drinking too much caffeine or watching too much television that could theoretically be described as addictive behaviours, they are more likely to be habitual behaviours that are important in an individual’s life but actually cause little or no problems. As such, these behaviours should not be described as an addiction unless the behaviour causes significant psychological and/or physiological effects in their day-to-day lives.

Totally bananas for an apple source: A brief look at fruit fetishism
In a previous blog I briefly examined sitophilia, a sexual paraphilia in which the individual has an erotic attraction to (and derives sexual arousal from) food. In that blog I noted that there has long been an association between eating and sexual behaviour on many different levels. More specifically, I noted:
“Eating and sex are both basic human needs and sometimes interact more directly. Many would also agree that eating (in and of itself) can be a sensual activity. There are also some foods that are considered to be aphrodisiacs. For example, foodstuffs such as oysters and chocolate are considered to have aphrodisiac properties (even if there is a lack of empirical evidence). The important factor is that if people believe the food in question has such arousing properties then there is likely to be some kind of a placebo effect”.
One (arguable) sub-type of sitophilia relates to those individuals that have fruit fetishes and/or specifically use fruit as part of their day-to-day sexual activity. Fruit fetishism also has overlapping behavioural and psychological characteristics with other fetishes that I have written about previously including ‘wet and messy’ fetishism and Nyotaimori (i.e., eating a variety of foods or a whole meal off somebody’s naked body). Almost every article about fruit fetishes on the Internet mentions the fact that some types of fruit (most noticeably bananas) can be used as a dildo substitute for both men and women (and used both anally and vaginally). For instance, the Wikipedia entry on ‘food play’ notes:
“Certain fruits (e.g., bananas), vegetables (e.g., cucumbers and zucchinis) and processed meat (e.g., sausages and hot dogs), if used safely, may be fetish objects because they have a phallic shape, and can be substitutes for dildos, useful for vaginal or anal penetration. Other foods are so constituted that they can be sexually penetrated by a male…Francesco Morackini, an Austrian designer and artist, designed and created the first home Dildo Maker. It allows phallic food to be sculpted into an even more phallic shape for easier insertion…Other fruits are so constituted that they can be sexually penetrated by a male, if an appropriate hole is drilled in them. In the novel Portnoy’s Complaint by Philip Roth, the main character, Alexander Portnoy, masturbates using a cored-out apple”.
There are numerous references to sexual experiences involving fruit in popular culture. The most infamous is the scene in 9½ Weeks where John Gray (played by Mickey Rourke) feeds food erotically to his blindfolded lover Elizabeth McGraw (played by Kim Basinger) during foreplay. Sex with fruit is discussed in the 1991 Jim Jarmusch film Night On Earth. In the scene set in Rome, the taxicab driver Gino (played by Roberto Benigni) confesses to his passenger who happens to be a priest (played by Paolo Bonacelli) of having had sex with a pumpkin as a child (and before you all email me at once, pumpkins are fruits not vegetables). In the film, Gino confesses:
“I lived in the country, where there weren’t many women, and though you’re still a kid, inside you feel a man’s feeling, and there was no way to relieve this feeling. So the idea, not mine but a real intelligent friend of mine’s, of relieving ourselves with, to make love with…how do I say this? With pumpkins. Pumpkins. Warm, soft, damp, with seeds inside, so round – and we would – toom ta toom – help me find the words, Father – we relieved ourselves with these pumpkins”.
As you can probably guess, there is almost nothing in the academic literature on fruit fetishism. In a small article on ‘phallic fruit fetish’ in the online Urban Dictionary by Daniel Gonzales, he wrote that:
“[Phallic fruit fetish is a ‘disorder’ popularized by gay Quaker performing artist Peterson Toscano in his play ‘Time In The Homo No Mo Halfway House’ about his time spent as a patient in a Christian residential program to ‘cure’ gay people. Another resident in the program suffered from Phallic Fruit Fetish (or PFF) and had a persistent desire to commit sexual acts with phallic shaped fruits. The problem was alleviated when all phallic shaped fruits were removed from the facility. Rev. Smid ordered all bananas removed from the house upon learning of a patient’s phallic fruit fetish”.
Academically there are well over 100 papers and chapters on the topic of rectal foreign bodies and the list of objects and items that have been removed by doctors is almost as long as the number of papers. Many of these report the removal of fruit stuck in rectums (bananas and apples). Other papers report cucumbers as rectal foreign bodies (but reported as vegetables, but like pumpkins are actually fruits). My previous blog on rectal foreign bodies also provided a long list of items that had been medically removed from the rectum including drink containers (e.g., glass bottles, plastic bottles, peanut butter jars, glass tumblers), sporting items (e.g., baseballs, tennis balls), household and kitchen objects (e.g., candles, light bulbs, broomstick handle, spatulas, mortar pestle), sex toys (e.g., vibrators, dildos), and improvised objects (e.g., a sand-filled bicycle inner tubing, plastic fist and forearm, shoehorn, axe handles, aluminium money tube, whip handles, soldering irons, glass tubes, and frozen pigs tails). In a 2010 review by Dr. Joel Goldberg and Dr. Scott Steele published in Surgical Clinics of North America, the authors noted:
“Smooth objects, such as bottles, fruits and vegetables, dildos, and vibrators, cannot always be grasped, and caution should be taken to ensure that they are not broken inside the patient. In the cases of fruits and vegetables, however, either grasping or breaking apart the object is a well-described technique that aids in the removal of the foreign body”.
Breaking up the fruit appears to be an obvious method for retrieving rectal foreign bodies but a 2014 paper by Dr. Abbas Aras and colleagues in the journal Surgical Techniques Development claimed they had a new method outlined on their paper ‘A new and simple extraction technique for rectal foreign bodies: removing by cutting into small pieces’. They wrote about the case of a radish being stuck inside the rectum of a 53-year old male. They reported:
“The purposes of insertion and types of foreign bodies in rectum show great variation. Rectal foreign bodies need to be removed without giving damage to intestinal wall and this should be done in the easiest possible way. We have reported a new and a simple technique. It is easy to apply and safe. A patient was admitted to our clinic with a rectal foreign body (radish) which was successfully removed by cutting it into small pieces. We conclude that different kinds of rectal foreign bodies, especially fruit and vegetables, can be removed by this technique”.
Fruit fetishism and/or engaging in sexual practices with fruit are probably more widespread than might be initially imagined and there appears to be few problems from a psychological perspective. However, as the medical literature has frequently reported, help is sought when fruit is used in sexual practices (most commonly masturbation) and gets stuck inside a person’s rectal passage.

Naming desire: A personal look at my new job title
Back in 2002, I was incredibly proud when I became one of the youngest full Professors in the UK when I was bestowed the title of Professor of Gambling Studies based on my research contribitions to the gambling studies field. Anyone that has followed my career over the last decade (or this blog over the last four years) will no doubt have realised that my research interests and expertise include a lot more than gambling.
Although I still publish a lot of papers on gambling (12 to 17 papers per calendar year; see Appendix 1 below) I have carried out more and more research into non-gambling addictions and over the last six years (2010-2015) my refereed journal outputs on gambling have only constituted one-third of all my refereed journal outputs (32%) (see Appendix 1 and Figure 1).
The overwhelming majority of my published refereed papers since January 2010 (n=246; 88%) concern behavioural addictions (i.e., gambling addiction, videogame addiction, internet addiction, work addiction, sex addiction, exercise addiction, shopping addiction, dancing addiction, etc.). If gambling addiction is removed from these papers, this still leaves 56% of all my papers during the 2010-2015 period concerning other behavioural addictions (n=158). The remainder of my refereed journal papers (34 papers; 12%) mainly concern the topic of mindfulness carried out with my colleagues Edo Shonin and William Van Gordon. Even my three books in the 2010-2105 timeframe have been on three totally separate topics (i.e., problem gambling, internet addiction and mindfulness). Of my 71 book chapters in this 2010-2015 period, 22 have been on gambling addiction, 41 have been on other behavioural addictions, and 8 have concerned other topics (see Figure 2). In the ‘Further reading’ section below is some of the papers that I have published this year and even a quick glance will highlight that gambling papers are in the minority.
It is also worth noting that I am one of the most highly cited academics in the UK (soemthig else that I am very proud of) and a quick look at my Google Scholar citations profile (currently over 24,500 citations as of October 31, 2015) that of my top ten most highly cited papers, only one is on gambling adiction and the other nine concern my papers on videogame addiction and internet addiction.
Basically, my job title didn’t reflect what I was actually doing on the research front. And this is the very argument I put to my employer (Nottingham Trent University) a number of weeks ago. As far as I am aware, I am the first professor at NTU to ever ask for my title to be changed but last week I was informed by my line manager that the university was convinced by the case I put forward and from now on I will be Professor of Behavioural Addiction.
This new title change has pleased me greatly and of course subsumes the vast majority of the research that I am doing (including my research into gambling addiction). I don’t think I will ever stop carrying out research in the gambling field but my new job title will stop me feeling guilty about working in non-gambling areas. It may also stop some of few abusive emails I get regarding my blogs (saying in very colourful language that I should stop writing about other behavioural addictions and sexual paraphilias and “write about what I get paid to do”). Firstly, I would point out to these individuals that I don’t get paid to write my personal blog and even if I did, I write all my blogs in my spare time.
If you’ve read this far, then thank you. I promise normal service will be resumed in my next blog when it will be about something other than myself.

Cured meets: Treating addictive behaviours
Addiction is a highly prevalent problem within today’s society and there is a lot of time and many spent in trying to prevent and treat the behaviour. There has also been a move towards getting addicts motivated to want to change their behaviour. The most influential model worldwide is probably the ‘stages of change’ model by Dr. James Prochaska and Dr, Carlo Di Clemente that identifies an individual’s ‘readiness for change’ and tries to get a person to a position where they are highly motivated to change their behaviour. The individual stages of this model are:
- Precontemplation – This is where the person unaware of the consequences of his or her own behaviour and no change in behaviour is foreseeable.
- Contemplation – This is where the person aware problem exists and is contemplating change.
- Preparation – This is where the person has decided to change in the near future (e.g., New Year resolution).
- Action – This is where the person effects change (e.g., gets rid of all association items related to the behaviour).
- Maintenance – This is where the person consolidates behaviour change over time.
- Relapse – This where the person reverts to a former behaviour pattern (e.g., contemplation, preparation).
People can stay in one stage for a long time and it is also possible for unassisted change such “maturing out” or “spontaneous remission”. Various techniques can be used to help people prepare for readiness include motivational techniques, behavioural self-training, skills training, stress management training, anger management training, relaxation training, aerobic exercise, relapse prevention, and lifestyle modification. The goal of treatment can be either abstinence or simply to cut down.
The intervention and treatment options for the treatment of addiction include, but are not limited to counselling/psychotherapies, behavioural therapies, cognitive-behavioural therapies, self-help therapies, pharmacotherapies, residential therapies, minimal interventions and combinations of these (i.e., multi-modal treatment packages). The most important of these are outlined below.
Pharmacotherapy: Pharmacological interventions basically consist of addicts being given a drug to help overcome their addiction. These are mainly given to those people with chemical addictions (e.g., nicotine, alcohol, heroin, etc.) but are increasingly being used for those with behavioural addictions (e.g., gambling, sex, work, exercise, etc.). For instance, some drugs produce an unpleasant reaction when used in combination with the drug of dependence, replacing the positive effects of the drug of dependence with a negative reaction. For instance, alcoholics are sometimes prescribed disulfiram (more commonly known as Antabuse), that when combined with alcohol may produce nausea and vomiting. Other common therapies include methadone and the use of opioid antagonists (such as nalaxone or naltrexene) for heroin addiction. The methadone prevents withdrawal symptoms, block the effects of heroin use, and decreases craving. The main criticism of all these treatments is that although the symptoms may be being treated, the underlying reasons for the addictions may be being ignored. On a more pragmatic level, what happens when the drug is taken away? Often, the addicts return to their addiction if this is the only method of treatment used.
Behavioural therapy: Behavioural therapies are based on the view that addiction is a learned maladaptive behaviour and can therefore be ‘unlearned’. These have mainly been based on the classical conditioning paradigm and include aversion therapy, in vivo desensitisation, imaginal desensitisation, systematic desensitisation, relaxation therapy, covert sensitisation, and satiation therapy. All of these therapies focus on cue exposure, and relapse triggers (like the sight and smell of alcohol/drugs, walking through a neighbourhood where casinos are abundant, pay day, arguments, pressure, etc.). The theory is that through repeated exposure to ‘relapse triggers’ in the absence of the addiction, the addict learns to stay addiction free in high-risk situations. It could be argued that if the addiction is caused by some underlying psychological problem, (rather than a learned maladaptive behaviour), then behavioural therapy would at best only eliminate the behaviour but not the problem. This therefore means that the addictive behaviour may well have been curtailed but the problem is still there so the person will perhaps engage in a different addictive behaviour instead.
Cognitive-behavioural therapy: A more recent development in the treatment of addictive behaviours is the use of cognitive-behavioural therapies (CBT). There are many different CBT approaches that have been used in the treatment of addictive behaviours including rational emotive therapy, motivational interviewing, and relapse prevention. The techniques assume that addiction is a means of coping with difficult situations, dysphoric mood, and peer pressure. Treatment aims to help addicts recognise high-risk situations and either avoid or cope with them without use of the addictive behaviour. In relapse prevention, the therapist helps to identify situations that present a risk for relapse (both intrapersonal and interpersonal). Relapse prevention provides the addict with techniques to learn how to cope with temptation (positive self statements, decision review, and distraction activities), coupled with the use of covert modelling (i.e., practicing coping skills in one’s imagination). It also provides skills for coping with lapses (by redefining what is happening), and utilizes graded practice (a desensitization technique where addicts encounter real life situations slowly). Overall, CBT approaches are better researched than the other psychological methods in addiction but are probably no more effective (Luty, 2003).
Psychotherapy: Psychotherapy can include everything from Freudian psychoanalysis and transactional analysis, to more recent innovations like drama therapy, family therapy and minimalist intervention strategies. The therapy can take place as an individual, as a couple, as a family, as a group and is basically viewed as a ‘talking cure’ consisting of regular sessions with a psychotherapist over a period of time. Most psychotherapies view maladaptive behaviour as the symptom of other underlying problems. Psychotherapy often is very eclectic by trying to meet the needs of the individual and helping the addict develop coping strategies. If the problem is resolved, the addiction should disappear. In some ways, this is the therapeutic opposite of pharmacotherapy and behavioural therapy (which treats the symptoms rather than the underlying cause). There has been little evaluation of its effectiveness although most addicts go through at least some form of counselling during the treatment process.
Self-help therapy: The most popular self-help therapy worldwide is the Minnesota Model 12-Step Programme (e.g., Alcoholics Anonymous, Gamblers Anonymous, Narcotics Anonymous, Overeaters Anonymous, Sexaholics Anonymous, etc.). This treatment programme uses a group therapy technique and uses only ex-addicts as helpers. Addicts attending 12-Step groups involves them accepting personal responsibility and views the behaviour as an addiction that cannot be cured but merely arrested. To some it becomes a way of life both spiritually and socially and compared with almost all other treatments it is especially cost-effective (even if other treatments have greater success rates) as the organization makes no financial demands on members or the community. For the therapy to work, the 12-Step Programme asserts that the addict must come to them voluntarily and must really want to stop engaging in their addictive behaviour. Further to this, they are only allowed to join once they have reached “rock bottom”. To date there has been little systematic study of 12-Step groups but drop out rates are very high (typically 80-90%). There are a number of problems preventing evaluation, particularly anonymity, sample bias, and what the criterion for success is. The empirical evidence suggests that self-help support groups’ complement formal treatment options and can support standardized psychosocial interventions.
When examining all the literature on the treatment of addiction, there are a number of key conclusions that can be drawn. These include that: (i) treatment must be readily available, (ii) no single treatment is appropriate for all individuals., (iii) it is better for an addict to be treated than not to be treated, (iv) it does not seem to matter which treatment an addict engages in as no single treatment has been shown to be demonstrably better than any other, (v) a variety of treatments simultaneously appear to be beneficial to the addict, (vi) individual needs of the addict have to be met (i.e., the treatment should be fitted to the addict including being gender-specific and culture-specific), (vi) clients with co-existing addiction disorders should receive services that are integrated, (vii) remaining in treatment for an adequate period of time is critical for treatment effectiveness, (viii) medications are an important element of treatment for many patients, especially when combined with counselling and other behavioural therapies, (ix) recovery from addiction can be a long-term process and frequently requires multiple episodes of treatment, (x) there is a direct association between the length of time spent in treatment and positive outcomes, and (xi) the duration of treatment interventions is determined by individual needs, and there are no pre-set limits to the duration of treatment.

Strange fascinations: A brief look at unusual compulsive and addictive behaviours
In previous blogs, I have examined lots of strange types of addictive and compulsive behaviours including compulsive singing, compulsive hoarding, carrot eating addiction, Argentine tango addiction, compulsive nose-picking, compulsive punning, compulsive helping, obsessive teeth whitening, compulsive list-making, chewing gum addiction, hair dryer addiction, wealth addiction, and Google Glass addiction (to name just a few).
However, while doing some research for a paper I am writing on ‘fishing addiction’ (yes, honestly), I came across an interesting paper on unusual compulsive behaviours caused by individuals receiving medication for Parkinson’s disease ([PD] a degenerative disorder of the central nervous system) and multiple system atrophy ([MSA] a degenerative neurological disorder in which nerve cells inside the brain start to degenerate and with symptoms similar to Parkinson’s disease).
In the gambling studies field there are now numerous papers that have been published showing that some Parkinson’s patients develop compulsive gambling after being treated for PD. According to the Parkinsons.co.uk website, those undergoing PD treatment can have many side effects including addictive gambling, obsessive shopping, binge eating, and hypersexuality. The website also notes other types of compulsive behaviour that have been associated with PD medication including “punding or compulsive hobbyism [when someone does things such as collecting, sorting or continually handling objects]. It may also be experienced as (i) a deep fascination with taking technical equipment apart without always knowing how to put it back together again, (ii) hoarding things, (iii) pointless driving or walking, and (iv) talking in long monologues without any real content”.
The paper that caught my eye was published in a 2007 issue of the journal Parkinsonism and Related Disorders by Dr. Andrew McKeon and his colleagues. They reported seven case studies of unusual compulsive behaviours after treating their patients with dopamine agonist therapy (i.e., treatment that activates dopamine receptors in the body). The paper described some compulsive behaviours that most people would not necessarily associate with being problematic. Below is a brief description of the seven cases that I have taken verbatim from the paper.
- Patient 1: “A 65-year-old female with PD for 9 years developed compulsive eating, and also felt compelled to repetitively weigh herself at frequent intervals during the day and at night. She found her behavior both purposeless and repetitive. Obsessive thoughts were also a feature, as the patient ‘had to’ weigh herself three times each occasion she used the weighing scales”.
- Patient 2: “A 67-year-old female with PD for 8 years played computer games and solitaire card games for hours on end, often continuing to do so through the night. She did not enjoy the experience and found it purposeless, but did so as she felt she had ‘to be doing something’. She also developed compulsive eating and gambling”.
- Patient 3: “A 48-year-old male with PD for 5 years, with little prior interest, developed an intense interest and fascination with fishing. His wife was concerned that he fished incessantly for days on end, and his interest did not abate despite never catching anything. This patient also developed compulsive shopping, spending large amounts of time and money in thrift stores”.
- Patient 4: “A 53-year-old male with PD for 13 years became intensely interested in lawn care. He would use a machine to blow leaves for 6h without rest, finding it difficult to disengage from the activity, as he found the repetitive behavior soothing. He also developed compulsive gambling”.
- Patient 5: “The wife of a 52-year-old male with an 11-year history of PD complained that her husband now spent all of his time on his hobbies, to the detriment of their marriage. The patient made small stained glass windows, day and night. In addition, he would frequently stay awake arranging rocks into piles in their yard, intending to build a wall, but never doing so. He would start multiple projects but complete nothing. He was also noted to have become hypersexual, demanding sexual intercourse from his wife several times daily”.
- Patient 6: “This 60-year-old male, with a history of alcohol abuse and ultimately diagnosed with MSA, relentlessly watched the clock, locked and unlocked doors and continually arranged and lined up small objects on his desk. He also became hyperphagic and hypersexual, developing an intense fascination with pornographic films”.
- Patient 7: “The wife of a 59-year-old male with PD for 1 year described how her husband dressed and undressed several times daily. On one occasion, while guests were at their house for dinner, he spent most of his time in his bedroom repeatedly changing from one pair of trousers into another. This behavior deteriorated considerably on increasing levodopa dose to 1100mg/day, and on a subsequent occasion after reducing quetiapine from 100 to 75 mg/day”.
These cases highlight that the compulsive behaviours that develop following dopamine agonist therapy often co-occur with one or more other compulsive behaviour and that much of these behaviours are repetitive and unwanted. As the authors noted:
“The temporal association between medication initiation and the onset of these behaviors led to our suspicion that medications were causative. In the aggregate, these patients illustrate that the behaviors provoked by drug therapy in parkinsonism cover a broad spectrum, ranging from purposeless and repetitive to complex, reward-oriented behaviors. Punding is the term typically applied to the former, and was seen in Patient 5 (arranging rocks into piles) and Patient 6 (lining up small objects on a desk)…Previous descriptions of pathological behaviors occur- ring with dopaminergic therapy in PD have been notable for the absence of obsessive thoughts accompanying compulsive behaviors, unlike Patient 1 who was remark- able for a counting ritual accompanying repetitive use of a weighing scale. In six of the seven cases, other reward- seeking behaviors (gambling, shopping, hypersexuality or overeating) were present and contemporaneous with these other unusual compulsive behaviors. This suggests that all of these behaviors, while phenomenologically distinct, are all part of the range of psychopathology encapsulated by obsessive-compulsive spectrum disorders”.
According to the Parkinsons.co.uk website, PD sufferers are more likely to experience impulsive and compulsive behaviour if the person is (i) diagnosed with Parkinson’s at a young age, (ii) male, (iii) single and live alone, (iv) a smoker, and (v) someone with a personal or family history of addictive behaviour. The same article also notes that if the PD sufferer has “a history of ‘risk-taking’, such as gambling, drug abuse or alcoholism, [they] may be more likely to develop dopamine addiction”. This is where the PD sufferer takes more of their medication than is needed to control their Parkinson’s symptoms (and known as dopamine dysregulation syndrome). Similarly, Dr. McKeon and colleagues concluded:
“Previously described associated clinical features include a prior history of depressed mood (four patients in this series), disinhibition, irritability and appetite disturbance…A history of problems with impulse control prior to the diagnosis of PD may be a risk factor for developing compulsive behaviors with dopaminergic therapies…although this only pertained to Patient 6…The compulsions were not found to be troublesome by three patients, with complaints regarding behavioral change coming from the patient’s spouse. Our observations affirm the need to check with both patient and family at follow-up visits for the emergence of a variety of troublesome pathological behaviors that may result from dopaminergic therapy, particularly dopamine agonists”.
