MMPI ratings of suicide risk

Among past attempts to use MMPI data to predict suicidal behavior, there has been a lack of research on the ability of clinicians to identify MMPI profiles of suicidal persons. In this study, the MMPI profiles of 20 male psychiatric patients who committed suicide and the MMPI profiles of 20 male patients who did not attempt or commit suicide were presented to six clinical psychologists with expertise in MMPI interpretation. The clinicians were asked to classify each MMPI profile as coming from a patient who did or did not later commit suicide, and to rate eight variables thought to be relevant to the assessment of suicide risk. Data analysis revealed that the clinicians could not identify suicide and nonsuicide patients from their MMPI profiles. Furthermore, the ratings of the eight suicide variable did not differentiate suicide and nonsuicide patients.
