The ARCH Lab Contributes to Two Papers on the 2014 Ontario Child Health Study Emotional Behavioural Scales

The ARCH Lab contributed to two papers on The 2014 Ontario Child Health Study Emotional Behavioural Scales (OCHS-EBS), Part I “A checklist for dimensional measurement of selected DSM-5 disorders” and Part II “Psychometric adequacy for categorical measurement of selected DSM-5 disorders”.

The aim of the first paper was to describe the development and psychometric properties of the OCHS-EBS for the measurement of seven disorders based on criteria from the Diagnostic and Statistical Manuel of Mental Disorders (DSM-5). In a sample of 280 children and their caregivers, the OCHS-EBS was found to be a reliable and valid measurement of: Generalized Anxiety Disorder (GAD), Separation Anxiety (SA), Major Depressive Disorder (MDD), Social Phobia (SA), Attention-Deficit Hyperactivity Disorder (ADHD), Oppositional Defiant Disorder (ODD) and Conduct Disorder (CD).

The second article sought to compare the reliability and validity of the OCHS-EBS to the Mini International Neuropsychiatric Interview for Children and Adolescents (MINI-KID) – a widely used structured diagnostic interview for youth. Specifically, using a sample of 283 parent-youth pairs, the authors compared the OCHS-EBS and the MINI-KID in classifying CD, ODD, ADHD, MDD, GAD and SAD based on DSM-5 criteria. Results indicated that the OCHS-EBS and MINI-KID achieved comparable levels of reliability and validity when classifying child psychiatric conditions.

Together the results of these two papers highlight the validity of the OCHS-EBS as a reliable measure for the presence of DSM-5 disorders in child and adolescent populations.
