Counteracting the drinker’s misperceptions about alcohol’s effects is an important part of relapse prevention. To accomplish this goal, the therapist first elicits the client’s positive expectations about alcohol’s effects using either standardized questionnaires or clinical interviews. Positive expectancies regarding alcohol’s effects often are based on myths or placebo effects of alcohol (i.e., effects that occur because the drinker expects them to, not because alcohol causes the appropriate physiological changes). In particular, considerable research has demonstrated that alcohol’s perceived positive effects on social behavior are often mediated by placebo effects, resulting from both expectations (i.e., “set”) and the environment (i.e., “setting”) in which drinking takes place (Marlatt and Rohsenow 1981). Subsequently, the therapist can address each expectancy, using cognitive restructuring (which is discussed later in this section) and education about research findings. The therapist also can use examples from the client’s own experience to dispel myths and encourage the client to consider both the immediate and the delayed consequences of drinking.
