Validation of a Chinese Version of the Obsessive Beliefs Questionnaire

Cognitive models of obsessive-compulsive disorder (OCD) assign a central role to maladaptive beliefs. Evaluation of these OCD beliefs in Western countries is commonly accomplished using the Obsessive Beliefs Questionnaire (OBQ) and is important for conceptualizing and treating OCD. It remains unclear if Western models of OCD beliefs are appropriate for sufferers in some non-Western regions, such as China, which represents nearly 20 % of the world population. Thus, the aim of present study is to examine the psychometric properties of a Chinese translation of the OBQ in three samples: 1,322 undergraduates, 139 patients with OCD, and 79 patients with other anxiety disorders. Confirmatory factor analysis revealed poor fit for multiple English-based models of the OBQ. However, an exploratory factor analysis supported an OBQ model that differs slightly from the English version: (1) Perfectionism/Certainty (P/C), (2) Over-Estimation of Threat (T), (3) Importance of Thoughts/Responsibility for Harm (I/R). This Chinese version of the OBQ (C-OBQ) contains 30 items and shows adequate internal consistency, test-retest reliability, construct validity, and criterion-related validity. In China, the C-OBQ may be a useful instrument for delineating cognitive patterns associated with OCD to inform research and treatment.
