Suicidality in opioid-dependent subjects.

Clinical Research and Evaluation Facility, Nathan S. Kline Institute for Psychiatric Research and Rockland Psychiatric Center, Orangeburg, New York, USA.

We determined suicide attempt characteristics in 160 opioid-dependent subjects. Three aspects of suicide vulnerability were also examined: familial aggregation of suicidal behaviors, degree of aggression/impulsivity, and smoking. Forty-eight percent of subjects had a personal history of suicide attempt. A personal history of suicide attempt was associated with an early onset of heroin use, but not with gender differences. A family history of suicide was a progressive risk factor for suicide attempt. Subjects with a personal history of suicide attempt had a higher degree of aggression/impulsivity and smoked more cigarettes. In conclusion, opioid-dependent subjects who attempt suicide show familial aggregation and clinical expressions of suicidal liability similar to those described in other psychiatric groups.
