MMPI evaluation of erectile dysfunction: failure of organic vs. psychogenic decision rules

This study examined previously published decision rules to ascertain the empirical utility of the MMPI in discriminating between organic and psychogenic erectile dysfunction. Subjects were 41 males who were being evaluated for prosthesis implant surgery. The mean overall 1-2-3 MMPI profile revealed diffuse somatic complaints, depression, and denial. Results indicate that the MMPI failed to discriminate between organic and psychogenic subgroups. Men with psychogenic erectile dysfunction evidenced neither significantly more nor less psychopathology on the MMPI than did those with objective organic findings.
