Suicide following psychiatric hospitalization.

The hypothesis was tested that following psychiatric hospitalization, those subjects who subsequently completed suicide would be distinguished from those who did not by the interaction of two circumstances: a state of defenselessness at the time of hospitalization, and experience of adverse life events following release from hospital. Subjects were 40 male VA psychiatric inpatients: 20 who completed suicide following release, and 20 controls matched on age, race, and time at risk in the community. Defenselessness (the incapacity to defend against distressful negative self-feelings) was defined in terms of scores derived from the extended Brief Psychiatric Rating Scale administered shortly after the patient's hospitalization. Adverse life events were eight events characterized simultaneously as undesirable, unlikely to have been initiated by the subject, and having a score of 30 or above on the Social Readjustment Rating Scale. In confirmation of the hypothesis, it was found that completed suicide subjects were significantly and appreciably more likely both to have had high defenselessness scores at the time of hospitalization and to have experienced adverse life events during the posthospitalization period, whereas neither circumstance in the absence of the other was predictive. The findings support the position that suicide is a response to experiences with self-threatening implications, in the face of personal incapacity to defend against, adapt to, or cope with such experiences.
