Abstract

BackgroundThe Obsessive-Compulsive Inventory-Revised OCI-R was designed to evaluate the severity of obsessive-compulsive symptoms in both clinical and non-clinical samples. The aim of the study was to evaluate the psychometric properties of a Chinese version of this scale.

MethodsThe Chinese version of the OCI-R was administered to both a non-clinical sample 209 undergraduate students and a clinical sample 56 obsessive-compulsive disorder OCD patients. Confirmatory factor analysis was conducted to examine the construct validity of the OCI-R in the non-clinical sample. The internal consistency at baseline and test-retest reliabilities at 4-week interval was examined in both the non-clinical and clinical samples.

ResultsThe confirmatory factor analysis of the non-clinical sample confirmed a 6-factor model suggested by the original authors of the instrument df = 120, RMSEA = 0.068, CFI = 0.88, NNFI = 0.85, GFI = 0.89. The internal consistency and test-retest reliability were at an acceptable range for both the non-clinical and clinical samples. The OCI-R also showed good clinical discrimination for patients with OCD from healthy controls.

ConclusionsThe Chinese version of the OCI-R is a valid and reliable instrument for measuring OCD symptoms in the Chinese context.
