The CAP control theory of drug abuse

The CAP theory of drug abuse emphasizes the interaction of cognitive-affective-pharmacogenic effects of drug taking. The belief that one is powerless to affect the environment and cope with stress plays a central role in the theory. The CAP theory is seen as being consistent with newer cognitive models which emphasize the role of internal thoughts and beliefs in the development of maladaptive behavior. Research findings support the hypothesis that an individual's belief in the ability to control a situation strongly influences behavior. Successful treatment of the drug abuser requires a multimodal approach which alters faulty thinking, teaches new interpersonal skills, helps the abuser cope with pain and anxiety, and encourages the development of a positive self-image.
