Identification of suicide attempters by means of MMPI profiles.

Used multivariate procedures to determine whether psychiatric patients who had made a suicide attempt immediately prior to hospitalization (N = 161) could be differentiated from nonsuicidal psychiatric patients (N = 161). Multivariate analysis of variance and cluster analysis failed to identify differences in the MMPI data of suicidal and nonsuicidal patients. In contrast, discriminant analysis produced a modest degree of differentiation that generally was maintained in the cross-validation.
