Autistic Traits in Adolescents who Self-harm

This is raw and analysis data for empirical study, entitled 'Autistic Traits in Adolescents who Self-harm'. The major objective of this study was to test the hypothesis that autistic traits predict the presence and recurrence of self-harm, and to determine any relationship mediated by the Interpersonal Psychological Theory of Suicide (IPTS). We examined autistic traits in 60 adolescents with suicidal or non-suicidal self-harm and 60 healthy controls. We assessed any interaction in Autistic Quotient (AQ) score and self-harm whether it is explained by thwarted belonging/perceived burdensomeness in the Interpersonal Needs Questionnaire (INQ); victimization in Olweus Bully/Victim Questionnaire (OBVQ); maltreatment in Childhood Trauma Questionnaire (CTQ). Impairments in communication (OR= 1.30) and social skill (OR= 1.28) predicted self-harm, yet the association became insignificant after the inclusion of thwarted belonging and perceived burdensomeness, which were independent predictors of the presence of self-harm. AQ social skill (OR= 2.24) and total (OR= 1.37) scores predicted recurrence of self-harm; the interactions were mediated by mostly thwarted belonging ( respectively, b value were 1.49 and 36.68)
