This study examined the risk factors for suicidal behavior in 149 human immunodeficiency virus positive patients in a treatment center in New Jersey. Approximately half of the patients attempted suicide. Suicide attempters were significantly younger, had a family history of suicidal behavior, & reported more childhood trauma. These data suggest that both distal & proximal risk factors are involved in suicidal behavior of human immunodeficiency virus positive patients. (22 refs) (SC)
