Psychometric Properties of the Greek Version of the Obsessive-Compulsive Inventory-Revised in a Non-Clinical Young Adult Sample

Abstract

Obsessive-Compulsive Inventory-Revised (OCI-R) is a self-report questionnaire that assesses the distress caused by a variety of OCD symptoms; OCI-R comprises of 18 items that are equally divided into six subscales: Checking, Washing, Obsessing, Neutralization, Ordering, and Hoarding. Research so far has shown that OCI-R is a psychometrically sound measure with excellent validity and reliability. It is also appropriate for clinical and non-clinical populations and has been translated into several languages and has been validated in diverse cultural contexts. The aim of the present study was to validate OCI-R in the Greek language and to examine its psychometric properties in a Greek non-clinical sample. Three hundred and seventy one university students participated in this study. Measures used were OCI-R, the Padua Inventory (PI), the Obsessive Beliefs Questionnaire-44 (OBQ-44), and the Depression Anxiety Stress Scale (DASS-21). Consequent analysis of collected data examined the factor structure of OCI-R and tested its convergent and divergent validity. The confirmatory factor analysis showed good fit for the model and replicated the results of other studies, meeting thus the requirements for the six-factor solution of the original scale. The Greek version of OCI-R maintained the good psychometric properties of the original English one. Internal consistency was excellent for the overall scale. Convergent and divergent validity was good and also confirmed previous similar findings.
