This paper assesses the psychometric properties of the French version of the Obsessive Beliefs Questionnaire (OBQ-44) and investigates whether the questionnaire discriminates between obsessive-compulsive disorder (OCD), anxious control (AC), and non-clinical control (NCC) participants. A confirmatory factor analysis suggested a poor fit of the model. An exploratory factor analysis replicated the original factor structure. The subscales were moderately intercorrelated and highly correlated with the total score. There was partial support for convergent/divergent validity of the OBQ-44. In analyses of variance comparing the three samples, the participants in the OCD sample scored significantly higher than the participants in the AC and NCC samples on all of the OBQ-44 scores. In analyses of covariance comparing the OCD and NCC samples while controlling for general distress and age, the participants with OCD scored significantly higher than the NCC participants on all of the OBQ-44 scores. Implications of the current study are discussed.

    ABSTRACT: 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.

    • "The OBQ measures the six previously-mentioned types of beliefs. Although there have been some differences across studies as to the precise factor structure of the OBQ, the best replicated structure consists of three correlated factors: (a) Inflated responsibility and overestimation of threat (RT); (b) perfection and intolerance of uncertainty (PC); and (c) overimportance and need to control one's thoughts (ICT; Julien et al., 2008 ; OCCWG, 2003). The OBQ has been used in regression analysis to predict OC symptoms in several crosssectional studies. "

    • "La relación entre las creencias de responsabilidad o la importancia dada a los pensamientos y los síntomas obsesivo-compulsivos es consistente con los hallazgos de estudios previos (v.g., Barret y Healy, 2003; Libby et al., 2004). De igual modo, la baja correlación del OBQ-CV con el C-YBOCS concuerda con los resultados de otras investigaciones en las que los índices han sido muy bajos o no signifi cativos, tanto en jóvenes (Coles et al., 2010; Wolters et al., 2011) como en adultos (Julien et al., 2008). Una posible explicación a esta baja relación entre el OBQ-CV y el C-YBOCS puede ser que en la puntuación total del OBQ-CV infl uyen tanto la severidad como el número de creencias que presenta el sujeto, mientras que en el C-YBOCS la puntuación depende únicamente de la severidad del síntoma principal, sin tener en cuenta el número de obsesiones y compulsiones distintas que se tengan.

    ABSTRACT: Psychometric properties of the Spanish version of the Obsessive Belief Questionnaire-Children's Version in a non-clinical sample. The aim of this study was the adaptation to Spanish of the Obsessive Belief Questionnaire-Children's Version (OBQ-CV) in a non-clinical sample. Confirmatory factor analyses revealed the best fit for a model of three factors (Perfectionism/Certainty, Importance/Control of Thoughts, and Responsibility/Threat Estimation) and one higher-order factor. Moreover, results showed that the Spanish OBQ-CV is a reliable measure. This version also showed good criterion validity with obsessive-compulsive symptom measures and with scores of beliefs relevant to obsessive-compulsive disorder. Lastly, this version showed good divergent validity with depression and anxiety measures.
