This study was designed to examine the types of stressful events that are related to adolescent suicidal behaviour. Adolescent inpatients who attempted suicide and a control group of high school students were compared on various types of stressors. The stressors were categorized according to their type (for example, discrete events versus chronic strains) and source (for example, family or friends). Compared to high school controls, adolescents who attempted suicide reported elevated levels of major negative events and exit events. Both chronic strains and discrete stressors were related to an increased severity of depression and suicidal ideation. The results support the notion that increased stress is related to adolescent suicidal behaviour. Different approaches to categorizing stress may improve the understanding of the relationship between stressful life events and suicide. Also, sex differences may influence the relationship between life stress and suicidal feelings.
