The authors retrospectively evaluated 106 patients diagnosed with major affective disorders. 53 patients with at least one suicide attempt were matched on a group basis with 53 patients who had never attempted suicide. In bivariate comparisons, suicidal patients were more likely to have been treated with antipsychotic & anxiolytic drugs, less likely to be married, have comorbid physical illnesses, & have been treated with antidepressants. Results support previously reported findings that marital status & treatment regimen may influence suicide risk. (26 refs.)
