Explaining the gender difference in self-reported suicide attempts: a nationally representative study of Norwegian adolescents.

Predictors of self-reported suicide attempts were studied cross-sectionally and prospectively in order to discern which variables may account for the gender difference in such reports. A representative sample of Norwegian students (N= 9,679) in grades 7-12 were followed from 1992 to 1994. More girls (10.4%) than boys (6.0%) reported a previous attempt and more girls (3.3%) than boys (1.9%) reported an attempt during the study period. The gender difference in previous suicide attempts was significantly reduced when depressed mood was controlled, and was no longer significant when disordered eating was included. There was no gender difference in future attempts when previous attempts, depressed mood, physical appearance, pubertal timing, and romantic involvement were controlled. Girls' higher level of risk factors may account for their higher level of self-reported nonfatal suicidal behavior.
