Validation of the Chinese Version of Obsessive-Compulsive Inventory-Revised.

Area of Science:

• Psychiatry and Clinical Psychology
• Psychometrics and Measurement

Background:

• The Obsessive-Compulsive Inventory-Revised (OCI-R) is a validated self-report measure for obsessive-compulsive symptoms.
• Its six dimensions include washing, obsessing, hoarding, ordering, checking, and neutralising.

Purpose of the Study:

• To validate the Chinese version of the OCI-R (C-OCI-R) in Hong Kong patients diagnosed with obsessive-compulsive disorder (OCD).

Main Methods:

• The C-OCI-R underwent translation and expert review. Internal consistency and test-retest reliability were assessed. Construct validity was examined using confirmatory factor analysis. Concurrent and divergent validity were evaluated against established scales like the Y-BOCS, Beck Depression Inventory-II, and Hamilton Depression Rating Scale.

Main Results:

• The C-OCI-R demonstrated excellent internal consistency (Cronbach's alpha = 0.92) and test-retest reliability (Spearman's rho = 0.96). Confirmatory factor analysis supported the original six-factor structure. Concurrent and divergent validity were established, though the neutralising and obsessing subscales require further refinement. Symptom structure was comparable to Western samples.
• 130 OCD patients participated in the study.

Conclusions:

• The C-OCI-R is a psychometrically sound and reliable instrument for assessing obsessive-compulsive symptom severity in Chinese patients with OCD.
• The findings support the cross-cultural applicability of the OCI-R for OCD assessment.
