Abstract

Background: Obsessive Compulsive Disorder (OCD) is one of the common psychiatric disorders among children and adolescent. Prevalence of child and adolescent OCD is 2% in Bangladesh. Gold standard Children's Yale-Brown Obsessive-Compulsive Scale (CY-BOCS) is a clinician-rated and most widely used scale in measurement of OCD symptom severity and thereby treatment response in children and adolescent age group. A validated scale for children and adolescent patient with OCD is needed for measuring symptom severity as well as treatment outcome in Bangladesh. Aim of the study: The aim of this study was to develop a culturally adapted and psychometrically validated Bangla version Children's Yale Brown Obsessive Compulsive Scale for use in Bangla speaking child and adolescent patients with obsessive compulsive disorder in Bangladesh. Methods: This validation study was conducted in the period of July 2016 to September 2017 in the department of Psychiatry, Bangabandhu Sheikh Mujib Medical University, Dhaka. In this study researcher applied Bangla version of Children's Yale Brown Obsessive- Compulsive Scale in 47 child and adolescent with OCD and assessed the validity (Content validity, Face validity, Convergent validity and Factor analysis) and reliability (Internal consistency, Inter-rater reliability, Test-retest reliability). Results: Age of the respondents were ranging from 8-17 years. Content validity and face validity was maintained by following standard procedures. Good convergent validity was found with culturally adapted Developmental and Well Being Assessment (DWABA) Bangla by using spearman's rho. Factor analysis revealed 2 components in the construct. Communalities were above accepted level. In assessing internal consistency, Cronbach's Alpha (a) value was 0.91, which reflects good reliability. Inter rater reliability was excellent for CY-BOCS total and each individual 10 items as the range of intraclass correlation was 0.96 to 0.98 which represented very .........
