Abstract
BackgroundThe Obsessive Beliefs Questionnaire-44 (OBQ-44) is originally developed by the Obsessive Compulsive Cognitions Working Group and has been translated into several languages. This paper is aimed to investigate the psychometric properties of the Chinese version of the Obsessive Beliefs Questionnaire-44 (OBQ-44) in both clinical and non-clinical samples.MethodsFive hundred and sixty-nine undergraduate volunteers and sixty-six OCD patients were included in the study. All participants have completed Chinese version of OBQ-44, Yale-Brown Obsessive-Compulsive Scale (Y-BOCS), and Beck Depression Inventory (BDI). Confirmatory factor analysis was conducted to examine the construct validity of Chinese version of OBQ-44. The internal consistency and test-retest reliabilities at 4-week interval were examined in both non-clinical and clinical groups.ResultsThe confirmatory factor analysis of the non-clinical sample confirmed a 3-factor model which was suggested by the original authors of the instrument (χ2/d.f = 2.96, GFI = 0.83, NFI = 0.82, CFI = 0.88 and RMSEA = 0.06). The internal consistency and test-retest reliability were at an acceptable range for the two samples.ConclusionsThe Chinese version of OBQ-44 is a valid and reliable instrument for assessing dysfunctional beliefs related to the etiology and maintenance of obsessions and compulsions.
Highlights
The Obsessive Beliefs Questionnaire-44 (OBQ-44) is originally developed by the Obsessive Compulsive Cognitions Working Group and has been translated into several languages
Validity statistics The convergent validity of OBQ-44 was assessed by calculating the correlations between OBQ-44 scores and the scores of Yale-Brown Obsessive-Compulsive Scale (Y-BOCS) and Beck Depression Inventory (BDI) in both non-clinical sample and clinical sample (Table 2)
The convergent validity of OBQ-44 was good with the OBQ-44 scores correlated stronger with Y-BOCS than BDI in non-clinical sample
Summary
The Obsessive Beliefs Questionnaire-44 (OBQ-44) is originally developed by the Obsessive Compulsive Cognitions Working Group and has been translated into several languages. This paper is aimed to investigate the psychometric properties of the Chinese version of the Obsessive Beliefs Questionnaire-44 (OBQ-44) in both clinical and non-clinical samples. It is important to develop reliable instruments with tested validity in different populations from different countries and cultures for recognizing specific dysfunctional belief domain. Wang et al BMC Psychiatry (2015) 15:188 has been translated into several languages and has validated clinical and non-clinical samples [7–11]. OBQ-44 was shown to have good psychometric properties in both clinical and non-clinical samples in different language versions. Most of these validations were done in western samples. To our knowledge, there is not currently a Chinese Version
