title: Specificity of belief domains in OCD: validation of the French version of the Obsessive Beliefs Questionnaire and a comparison across samples.
abstract: 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.
