Change in general and specific perceived locus of control in alcoholics as a function of treatment exposure.

Fifty alcoholics successfully completing a 2-month rehabilitation program were administered the I-E Scale and a drinking locus of control scale during their first week in treatment and again the week prior to discharge from treatment. A test--retest non-alcoholic control group was administered the I-E Scale at a 7-week interval. Alcoholics were significantly more internal with regard to their behavior in general and their drinking behavior in particular at the close of treatment than at the onset. The control group evidenced no change. It was suggested that the alcoholics perceived internality was a function of exposure to treatment rather than a predisposing personality dimension.
