Abstract

An attempt was made to evaluate the predictive validity for improvement of the Rorschach Prognostic Rating Scale (RPRS) and the MMPI. A group of untreated psychiatric outpatients (N = 40) and a group of outpatients treated with psychotherapy (N = 21) were given the Rorschach and MMPI before their assignment to the treatment or waiting list groups. After a waiting or treatment period of approximately 6 mo., each patient was clinically rated as improved or unimproved. The RPRS was significantly (p < .05) correlated with improvement in both the untreated (.38) and psychotherapy group (.43). The F scale of the MMPI was significantly correlated with improvement in both groups (.32 and .34 respectively). (29 ref.) (PsycINFO Database Record (c) 2006 APA, all rights reserved)
