Family history of suicide and impulsivity.
A family history of suicide indicates a raised risk for suicidal behavior; this liability might be familially transmitted as an impulsive-aggression trait. To examine the impulsivity factor, data from 258 abstinent drug dependent patients who were interviewed about their family history of suicidal behavior and who completed the Barratt Impulsivity Scale (BIS) were examined. The results showed that patients with a family history of suicidal behavior had significantly higher BIS scores for risk taking than patients without a family history of suicidal behavior. Also, patients with a family history of suicidal behavior who had themselves attempted suicide had significantly higher BIS scores for both impulsivity and risk taking than patients with a family history of suicidal behavior who had never attempted suicide.
