Abstract
From a family study of 286 alcoholics, 157 felons, 60 control subjects, and 1640 of their relatives, 130 solvent users were retrospectively identified. Risk for diagnosis of antisocial personality disorder was significantly elevated for all solvent users. Relatives, though not probands, were more likely to receive diagnoses of alcoholism and secondary depression, but this relationship appeared to be mediated by the presence of antisocial personality disorder. Solvent users were not at increased risk for primary depression or other psychiatric illnesses. Subjects reporting any solvent use also had significantly increased risk of suicidal ideation and suicide attempt compared to non-users, with half of the solvent users reporting suicidal ideation and 30% reporting a history of suicide attempt. However, risk for suicidal ideation and suicide attempt among solvent users appeared to covary with presence of antisocial personality disorder, alcoholism, and secondary depression rather than being specifically associated with solvent use.
