Our aim was to evaluate the psychometric properties of the Child Obsessive Compulsive Impact Scale - Revised (COIS-R), which is a measure of OCD-related functional impairment. The sample consisted of 396 Danish, Swedish, and Norwegian youth diagnosed with OCD according to the Diagnostic and Statistical Manual of Mental Disorders (4th edition) (48.9{\%} boys; mean age 12.9, SD=2.7). We used confirmatory factor analysis to evaluate the initial four-factor structure of the parent-reported measure (Daily Living Skills, School, Social, Family/Activities) and the three-factor structure of the child-reported measure (School, Social, Activities). We used the robust weighted least squares mean- and variance-adjusted estimator as applied in the MPLUS program (version 7.2). The parent-report format showed acceptable fit and the structure was equivalent across gender, age, and country. The child-report format showed poor fit and equivalent results across gender, age, and country. These findings indicate that the fit for the COIS-R original factor structure was acceptable for the parent-report but not for the child-report. The measure would benefit from revisions such as split sample procedure factor analyses with a large cross-cultural sample.",
