This study investigated the validity of norms for drug addicts from the Rathus Assertiveness Schedule. Subjects were 100 drug-abuse outpatients who completed the schedule, an audiotape analogue assessment, and another paper-and-pencil test adapted from both previous instruments. The discrepancy in test scores raised doubts as to the accuracy of measurement of the assertiveness schedule without an intermediate analogue intervention. Implications for the efficacy of audiotape devices are suggested.
