Recent models emphasized the importance in research of beliefs and its appraisal in the etiology and maintenance of OCD. The aim of the present study is the development and validation of a short form of the Obsessive Beliefs Questionnaire (OBQ, Belloch et al. 2003) in Mexican population. This topic was addressed through two different studies. Study 1: Exploratory factor analysis of the short version (200 non clinical subjects). The results show a different factor solution. Study 2: Testing for the equivalence of latent mean structures in multi-group analyses (200 and 202 non clinical subjects). A three-factor, 20 items, model emerged as the best factorial solution with similar psychometric properties to those of an English version (OBQ, Obsessive Beliefs Questionnaire, 2003). Given its consistency and repeatability, the Mexican version of the OBQ is a suitable instrument for the assessment of dysfunctional beliefs, although studies with clinical samples are needed.
