Groups of threatened, attempted & those who sometimes threatened and sometimes attempted suicide could be differentiated from neuropsychiatric nonsuicidal Ss by means of an MMPI item analysis. The 3 types of suicidal groups could not be distinguished from each other. Analysis of the differentiating items showed the existence of various patterns. Some items were common to all suicidal groups, some to the threat & attempt groups & some to the threat & threat/attempt groups.
