A longitudinal examination of the interpersonal theory of suicide and effects of school‐based suicide prevention interventions in a multinational study of adolescents

Abstract

Interpersonal theory assumptions were partially supported. Perceived interpersonal difficulties with parents were primarily related with SI, and risk behaviors and self-injury were important predictors of SA. Suicide prevention interventions may be effective by mitigating the hazardous effect of varying self-harm behaviors and may be further advanced by increasing parental involvement.
