Patterns of self‐destructive behaviour in schizophrenia

Abstract

Of 110 consecutive, young schizophrenic patients, 18 (16.4%) died during a follow-up period of 14–17 years from first admission. Fifteen of them met with a sudden death. Definite suicide was proven in 10 cases (9%). Suicide was associated with chronicity in course, social dependency, and lowered efficiency. Some type of warning was present in all suicide cases. The frequency of suicide thoughts and attempts was high in the whole material. Suicide attempts were associated with protracted non-regressive symptomatology, readmission to hospital, social intervention, and female sex. The disparity of characteristics between attempted suicide and definite suicide cases may partly be explained by the preponderance of women among the former and by the fact that only half of the suicidal deaths occurred when the frequency of attempts was at its peak. In attempted suicide in men their characteristics were compatible with those of the whole group, as well as with those of the suicide cases.
