The validity of the Rorschach Prognostic Rating Scale with incarcerated offenders.

Previous research has shown that the Rorschach Prognostic Rating Scale reliably predicts the adjustment capacity of various S types to a variety of situations. The present study investigated the efficacy of the RPRS to suggest the adjustment capacity of prisoners to various aspects of their institutional environment. Twenty-five male inmates of the Petersburg Federal Reformatory served as Ss. Group therapy, dormitory behavior, work progress adjustment ratings, and RPRS scores were obtained for each S. Intercorrelations among the adjustment measures and the RPRS total and component scores revealed no significant correlations between the adjustment measures and the RPRS total score. However, in employing a moximum R stepwise multiple correlation procedure with the RPRS compontnts, significant multiple Rs resulted for two of the three criterion measures. These results were discussed in terms of the earlier research with the RPRS, and suggestions for future research were made.
