Reliability, Validity, and Clinical Utility of the Dominic Interactive for Adolescents–Revised A DSM-5–Based Self-Report Screen for Mental Disorders, Borderline Personality Traits, and Suicidality

Objectives:The Dominic Interactive for Adolescents–Revised (DIA-R) is a multimedia self-report screen for 9 mental disorders, borderline personality traits, and suicidality defined by the fifth edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-5). This study aimed to examine the reliability and the validity of this instrument.Methods:French- and English-speaking adolescents aged 12 to 15 years (N = 447) were recruited from schools and clinical settings in Montreal and were evaluated twice. The internal consistency was estimated by Cronbach alpha coefficients and the test-retest reliability by intraclass correlation coefficients. Cutoff points on the DIA-R scales were determined by using clinically relevant measures for defining external validation criteria: the Schedule for Affective Disorders and Schizophrenia for School-Aged Children, the Beck Hopelessness Scale, and the Abbreviated-Diagnostic Interview for Borderlines. Receiver operating characteristic (ROC) analyses provided ac...
