Prevalence, course, incidence, and 1-year prediction of deliberate self-harm and suicide attempts in early Norwegian school adolescents.
In this survey of early Norwegian school adolescents, the prevalence, course, and incidence of self-harm behavior with or without suicide intent were examined, in addition to predictors of self-harm for a 1-year follow-up period. Lifetime prevalence rates of self-harm without suicide intent and suicide attempts were 2.9% and 3.0%, respectively, while 1-year incidence rates were 3.6% and 1.7%, respectively. In multivariate analysis, five predictors significantly differentiated self-harmers from non-self-harming adolescents. Early school adolescents having frequent or intense suicidal ideation over an extended time period and attempting self-harm repeatedly with or without suicide intent should be identified and offered treatment.
