Case reports are given of three patients, two suffering from compulsive shop-lifting and one from binge-eating, who responded to a week's treatment with imaginal desensitization after having failed to respond to prolonged interpretative psychotherapy. Expectancy of improvement did not appear to play a major role in their response, but it appears impossible to disprove that expectancy determines the response to this or any form of psychotherapy. Whether or not imaginal desensitization acted specifically in the present study, in view of its cost-efficacy it is suggested it is worthy of trial in impulse disorders which have persisted despite treatment.
