This study attempts to determine what American suicidologists perceive as the most important predictors of both fatal adolescent suicide as well as attempted suicide. A questionnaire consisting of 50 predictors gleaned from the literature was mailed to all members of the American Association of Suicidology in 1986. Results show that hopelessness, number of suicide attempts, verbal or written cues, suicide ideation, &loss or threatened loss of love object were the most important predictors.
