Psychometric Properties of the Obsessive-compulsive Inventory: The Persian Child Version; a Preliminary Study

Background: The Obsessive-Compulsive Inventory-Child Version (OCI-CV) is an approved self-report assessment tool that includes various domains of Obsessive-Compulsive Disorder (OCD). Objectives: This study was done to evaluate the psychometric properties of the OCI-CV in a sample of youth with OCD. Materials & Methods: This was a descriptive-analytic study. The subjects were 107 children and adolescents, 7 to 17 years old admitted to the Shafa hospital and Gill psychiatric center in the north of Iran in 2017-2018. The subjects with the diagnosis of OCD based on a diagnostic interview by a youth psychiatrist based on the DSM-5 were included in the study. They were assessed by the OCI-CV, Revised Children’s Manifest Anxiety Scale (RCMAS), and children depression inventory (CDI). Data were analyzed by SPSS v. 22, using Cronbach alpha, Pearson correlation coefficient, and exploratory factor analysis. Results: Youth with the Mean±SD age 11.18±3.1 years participated in the study. Results showed that 51% of the samples were girls. The internal consistency assessed by the Cronbach alpha for the total scale was 0.75, indicating good reliability. The Pearson correlation coefficient between OCI-CV and RCMAS was 0.584 (P=0.01), and between OCI-CV and CDI was 0.232 (P=0.05), showing an excellent concurrent validity. Construct validity showed that all subscales had a high correlation with the total score of the questionnaire and the correlation coefficient was significant (P<0.05). Conclusion: The Persian version of the OCI-CV has good psychometric characteristics in the clinical sample of youth with OCD.
