Alcoholic individuals often are assumed to deny personal responsibility for their alcoholism and to attribute causation to external situational factors. To investigate this assumption, in a 2×2 factorial design 20 alcoholics and 20 nonalcoholics made causal attributions for a recent personal drinking episode and for the audio-taped episode of a target individual who was described as either an alcoholic or a nonalcoholic. Results suggested that alcoholic subjects tended to make greater internal attributions for their own drinking than did nonalcoholic subjects. Subjects' attributions for the target individual depended on both the subjects' and targets' drinking histories. The results are discussed in terms of their relevance to models of alcoholism and to actor-observer differences in causal attributions.
