Aversion therapy is a form of psychological treatment in which the patient is exposed to a stimulus while simultaneously being subjected to some form of discomfort. This conditioning is intended to cause the patient to associate the stimulus with unpleasant sensations with the intention of quelling the targeted (sometimes compulsive) behavior.
Aversion therapies can take many forms, for example: placing unpleasant-tasting substances on the fingernails to discourage nail-chewing; pairing the use of an emetic with the experience of alcohol; or pairing behavior with electric shocks of mild to higher intensities.
The major use of aversion therapy is for the treatment of addiction to alcohol and other drugs. This form of treatment has been in continuous operation since 1932. The treatment is discussed in the Principles of Addiction Medicine, Chapter 8, published by the American Society of Addiction Medicine in 2003.
Among more-casual members of the self-help community, minor behavioral issues have been treated with the aid of an elastic band; the user snaps the band against his/her wrist while performing the undesirable behavior, seeking to create an unpleasant association and, ultimately, stop or the behavior pattern.
A strong precedent of the successful effects of aversion therapy is Disulfiram, or Antabuse, an acetaldehyde dehydrogenase inhibitor. This enzyme is responsible for a portion of the metabolism of alcohol and, when inhibited, causes hangover-like effects almost immediately after consuming alcohol, thus promoting an unpleasant association with a chemical dependence. Prior studies have shown Antabuse brings relief to the majority of its users, describing, "Patients who could not remain sober from one visit to the next achieved many months of continuous sobriety."
Traditional aversion therapy, which employed either chemical aversion or electrical aversion while effective, is commonly replaced with aversion imagery, a technique which is known as covert sensitization. Covert sensitization, or covert conditioning, involves provoking mental imagery to create associations with undesirable habits. While the efficacy of covert conditioning may be comparable to that of more-prevalent techniques in aversion therapy, these treatments may be combined to enhance an individual's likelihood for success in ending an unwanted habit.
Specifically, electrical aversion techniques have been demonstrated to significantly improve success rates among cigarette smokers. Additional longitudinal studies have repeated this effect, and showed cessation periods lasting at least 15 months post-trial. The examined trial involved 5 days of aversion therapy using an electric stimulus.
As an addictive substance, nicotine shows particular responsiveness to electric-stimulus-associated aversion therapy, especially when compared to traditional cessation methods. In addition, similar trials surveying chronic marijuana smokers yield higher cessation rates with only 5 days of treatment, with majorities of up to 85% remaining abstinent 15 months post-trial.
In compulsive habits
Many individuals struggle with unconscious or compulsive habits, such as chronic nailbiting, hair-pulling (Trichotillomania), or skin-picking (commonly associated with forms of Obsessive Compulsive Disorder as well as Trichotillomania). The effects of these habits are compounded by a lack of awareness, as the individual often does not make the conscious decision to engage in the particular behavior, in contrast to disorders of drug or alcohol addiction.
A relevant study of chronic nail-biters examined effects of electric stimulus, bitter substance (as applied to the nails), and placebo in biting reduction. Associating nail-biting with an electric stimulus or bitter substance showed similar levels of habit reduction as a result of aversion therapy, with over 80% of subjects exhibiting significant cessation rates up to 3 months post-trial. A similar study on the UCLA campus, examining electric stimulus conditioning on nail-biting alone, shared similar rapid and lasting results, with almost half of subjects ceasing entirely on the first day of treatment, and the majority having quit within 5 days.
Obsessive Compulsive Disorder
As well, in cases specific to the rituals of Obsessive Compulsive Disorder, using an electric stimulus to pair an unpleasant association with the undesired behavior has been successful in individual studies.
In popular culture
- In A Clockwork Orange and its film adaptation, the main character Alex is subjected to a form of experimental aversion therapy (the "Ludovico technique") aiming to stop his violent behavior.
- In the episode, There's No Disgrace Like Home from The Simpsons, the Simpsons family goes through shock aversion therapy in order to improve their overall behavior.
