Family history of suicidal behavior among suicide attempters.
Efforts to predict suicide and attempted suicide are hampered by their relative rarity on the one hand and the inadequate specificity of clinical characteristics and relevant antecedent events on the other; that is, these features are found widely among the nonsuicidal as well. In an effort to further understand these phenomena, the authors studied family history of suicidal behaviors (suicide, attempted suicide, and suicide threats) in 127 patients hospitalized following a suicide attempt. Patients with personality disorders (antisocial personality disorder, alcoholism, somatization disorder, and narcotic addiction), comprising 45 per cent of the sample, frequently reported a family history of these behaviors, most notably attempted suicide. Patients with primary affective disorder reported a family history of suicidal behaviors somewhat less often. The diagnoses grouped here as personality disorders (excepting alcoholism) contribute little to the suicide rate, while primary affective disorder contributes substantially. Although further data are needed, it is suggested that a family history of suicidal behavior in primary affective disorder should alert the clinician to heightened suicide risk, while a similar history in nonalcoholics with other psychiatric diagnoses is not particularly significant.
