AVERSION THERAPY

psychotherapy designed to cause a patient to reduce or avoid an undesirable behaviour pattern by conditioning him to associate the behaviour with an undesirable stimulus. The chief stimuli used in the therapy are electrical and chemical. In the electrical therapy, the patient is given a lightly painful shock whenever the undesirable behaviour is aroused; this method has been used in the treatment of sexual deviations. In the chemical therapy, the patient is given a drug that produces unpleasant effects, such as nausea, when combined with the undesirable behaviour; this method has been common in the treatment of alcoholism, the therapeutic drug and the alcohol together causing the nausea.
