The aim of the present study was to investigate the accuracy of self-reports of juvenile offenders on physical factors (e.g. sleep difficulties, weight-related behaviours and weight perceptions), health risk behaviours (e.g. alcohol use), trauma history (e.g. physical and sexual abuse) and psychological factors (e.g. anxiety, suicidal and self-harm behaviours). Self-reports obtained via a Health Questionnaire from 242 incarcerated juvenile offenders were compared with standardized measures (body mass index, Adolescent Psychopathology Scale and Child Trauma Questionnaire) to investigate the reliability (via construct validity) and veracity of their self-report. Using kappa estimates and receiver-operating characteristic curves, results generally showed high agreement across measures, suggesting that self-report questions from the health survey could all be used reliably. The degree of accuracy indicated that young offenders are as reliable as clinical and community samples of adolescents in their self-report. These findings have implications for routine assessments and practice evaluations that rely on self-report as the method of data collection and as the basis for clinical formulation and treatment planning.
