Personality and suicidal history in psychiatric patients.

The study sample comprised 575 psychiatric referrals for whom MMPI data were available. Patients were categorized according to suicidal history. The attempted suicide and nonsuicidal patients were differentiated significantly on the D, PD, MF, DY, ES, NE, EX, HO, SD, IP, ANX, and UNC scales. Important differences between the sexes emerged; whereas for men the profiles of the suicidal ideation and nonsuicidal patients were similar, for women those of the suicidal ideation and suicide attempt were similar. Male and female suicide attemptors correspond closely in the pattern and degree of deviation from the nonsuicidal patients of their own sex. The study indicates that patients who have a history of suicide attempts constitute a more psychologically disturbed group and points to a need for further examination of the meaning of suicidal ideation for men and women.
