Aversion therapy is an older behavioral modification technique based on classical conditioning. Learn about how it is used and its effectiveness.
There are many forms of behavioral therapy that a person can participate in to change unwanted and unhealthy behaviors. Aversion therapy can be used as one type of behavioral therapy, although it is not as widely used as it once was. An aversion therapy example is, in the case of a person who wants to quit smoking, to pair mild electric shocks with images of cigarettes. This negative association between pain and cigarettes will eventually affect a person’s behavior. Aversion therapy does not see widespread use by modern psychologists.
What Is Aversion Therapy?
Aversion therapy is based on the psychological principle of classical (or Pavlovian) conditioning.
Classical conditioning is when you pair two different stimuli together to create an associative memory. For example, you can pair an auditory tone with an electric shock to create an association. Then, when you play the tone later by itself, the tone alone will elicit a stress or fear response because it has been associated with the shock. Aversion therapy takes advantage of the same basic principles to change behavior.
Uses of Aversion Therapy
Aversion therapy has been used to treat conditions in which a person engages in unhealthy behaviors. While modern psychologists will likely use other treatment methods, aversion therapy can be used for the following challenges:
- Bad habits: Some people may seek to address bad habits, such as nail biting, with aversion therapy. For example, a greater proportion of people who went through aversion therapy had either ceased biting their nails or were biting less frequently three months later compared to people who experienced no aversion therapy.
- Smoking: Aversion therapy has been used for smoking cessation purposes.
- Gambling: Research has shown the use of aversion therapy in attempts to stop people from gambling.
- Alcoholism: In the past, alcoholism has been treated using aversion therapy procedures that either involved electrical, chemical or verbal imagery as the negative stimulus, which served to reduce drinking behavior amongst people struggling with alcohol use.
- Violence: Aversion therapy was also used to reduce violent behavior. Historically, this method has most often been utilized in correctional facilities.
Aversion therapy effectiveness has been a matter of contention. Many factors come into play when it comes to the effectiveness of aversion therapy, such as the treatment methods, aversive conditions that are used and whether the client continues to practice setback-prevention techniques after treatment finishes.
Usually, aversion therapy may be effective while a person is still undergoing treatment and in a clinical setting. The biggest problem is the high rate of setbacks that occur once the patient is back in real-world settings without the aversive stimulus (usually an electric shock) present.
Criticisms of Aversion Therapy
There has been much criticism of aversion therapy. The primary criticism is the lack of scientific rigor in the studies conducted. The studies that do exist on aversion therapy are mainly from the 1960s and 1970s and often their conclusions were drawn from very small samples. Sometimes these published studies included only one person.
Another major criticism of aversion therapy involves its use in the “treatment” of homosexuality. This issue wasn’t officially addressed by the American Psychological Association until 1994.
Today, there are more widely used, evidence-based therapies and treatment options available for addiction and other conditions.
