This study was designed to fulfill a twofold purpose. First, a 12-session reality therapy drug treatment program to help female drug abusers achieve a better recovery was developed. Second, based on previous research in reality therapy, the Index of Sense of Self-Control in Recovery for Drug Offenders was developed, and the instrument was validated using principal components analysis and confirmatory factor analysis. Later, ANCOVA was used to test the effectiveness of the treatment program. The participants were 48 female drug offenders, who were randomly assigned to equal-sized experimental and control groups. The results of the study showed significant differences in the posttest scores for the sense of self-determination and sense of self-control for the members of the two groups.
