Suicidal behaviors in depressed men with a family history of suicide: Effects of psychosocial factors and age

Effects of impaired social support and stressful life events on non-lethal suicidal behaviors were examined in a clinical sample of high-risk patients: depressed adult men with a family history of suicide or attempted suicide. All subjects (N = 79) were participants in the Mental Health Clinical Research Center (MHCRC) for the Study of Depression in Later Life (Duke University, USA). Outcome measures were self-reported one-year histories of three suicide-related ideation symptoms and attempted suicide. One-year prevalences for these outcomes were: death ideation, 58%; death wish, 48%; suicidal ideation, 57%; and attempted suicide, 11%. In adjusted models, none of the four measures of social support (network size, frequency of social interaction, receipt of instrumental support, and subjective social support) increased the odds of any outcome. Thus, in this high-risk group, impaired social support did not appear to increase the odds of one-year history of any form of suicide-related ideation or of attempted suicide. The number of negative life events experienced during the year before the study interview was not associated with increased odds of any ideation symptom, but was marginally higher in men who had attempted suicide during that year. Older age was significantly protective against explicit suicidal ideation (OR 0.95, CI 0.91-0.99) in this sample, but did not affect the odds of attempted suicide.
