The differences in factors associated with subgroups of adolescents in the continuum of deliberate self-harm phenomena were investigated. In an anonymous self-report survey of 6,020 adolescents, ages 15 & 16 years, 3.2% of adolescents reported deliberate self-harm with intent to die, 2.8% reported deliberate self-harm without intent to die, & 15% reported thoughts of deliberate self-harm without acts. Regression analysis found considerable overlap in vulnerability factors along the spectrum of deliberate self-harm thoughts & acts. A uniquely distinct relationship was found between deliberate self-harm of a friend & deliberate self-harm without intent to die on one hand & the deliberate self-harm of a family member with deliberate self-harm with intent to die on the other.
