Psychometric properties of the Brazilian version of the Obsessive Beliefs Questionnaire (OBQ-44).
The present study was designed to assess the psychometric properties of the Brazilian version of the Obsessive Beliefs Questionnaire (OBQ-44) in 104 patients with obsessive compulsive disorder (OCD) at the Hospital de Clínicas de Porto Alegre. The secondary objective was to ascertain whether a decline in OBQ-44 scores occurs after cognitive-behavioral group therapy (CBGT). Factor analysis identified three dysfunctional belief domains from the original scale. Internal consistency and reproducibility were very good and good, respectively. Sensitivity to treatment change (cognitive-behavioral group therapy) was good, and pre-post intervention standardized effect sizes (Cohen's d) were strong. The OBQ-44 plays an important role in this setting; as a user-friendly, self-administered instrument that lists the most common dysfunctional beliefs of OCD patients, it enables healthcare providers to assess whether their patients' beliefs change after treatment.
