Reports of adolescent suicidal behaviour have generally derived from clinical settings but population-based studies are likely to provide a clearer epidemiological view.
Non-fatal suicidal behaviours were studied in 1699 Australian 15-to 16-year-old secondary school students at 44 schools in the state of Victoria, Australia.
Self-reported episodes of self-harm were characterized using items from the Beck Suicide Intent Scale.
The 12 month weighted prevalence estimate for deliberate self-harm was 5.1%. The commonest forms were self-laceration (1.7%), self-poisoning (1.5%) and deliberate recklessness (1.8%). Self-poisoning and self-laceration were commoner in girls.
The prevalence of'true suicide attempts'was 0.2%. Most self-harmers did not perceive death as likely, plan self-harming episodes at length or inform others of the episodes.
Psychiatric morbidity had the strongest association with self-harm, an association which held for all subtypes.
Antisocial behaviour and substance abuse were associated with self-harm in girls but not boys.
Sexual activity was independently associated with self-harm in both genders.
Deliberate self-harm was common but the great majority of episodes were not'true suicide attempts'It is, therefore, possible that attributable mortality and morbidity may be greater in self-harmers without definite suicidal intent.
