Objectives: A shorter version of the Obsessive Beliefs Questionnaire (OBQ-44) is needed to promote the use of this measure in research and increase our understanding of cognitive phenomena maintaining obsessive-compulsive disorder (OCD). Additionally, an abbreviated version of the OBQ-44 would encourage frequent monitoring of dysfunctional beliefs in intensive care settings. This study aimed to validate a nine-item version of the questionnaire (OBQ-9)., Method: Participants seeking intensive/residential treatment for OCD (N = 311) completed relevant measures on a weekly basis and at admission and discharge., Results: A confirmatory factor analysis revealed that the OBQ-9's factor structure replicated the three-factor solution of the OBQ-44. The OBQ-9 demonstrated good psychometric properties and convergent validity and was sensitive to treatment effects. Finally, the OBQ-9 subscales predicted specific OCD dimensions over and above depressive symptoms., Conclusion: The OBQ-9 appears to be a psychometrically sound tool for routine outcome monitoring of dysfunctional beliefs in hospital-based settings., (© 2018 Wiley Periodicals, Inc.)

Objective: This study aimed to develop and validate the Distress Tolerance Scale-Short Form (DTS-SF), a modification of the original Distress Tolerance Scale, in a severe/complex sample of individuals with obsessive compulsive disorder (OCD). Currently, there are multiple self-report measurements of distress tolerance (DT), highlighting the need for a more refined measure., Method: Participants included 222 individuals with a primary diagnosis of OCD (57% male, average age = 31) seeking intensive/residential treatment. Participants completed surveys at admission, discharge, and each week., Results: An exploratory factor analysis revealed a one-factor solution representing overall DT ability. The DTS-SF was found to be sensitive to treatment effects. Appropriate associations between the DTS-SF and other measures were also found, with lower DT associated with greater OCD and depression severity and lower reported quality of life., Conclusion: The DTS-SF was found to be a valid and reliable measure with high clinical utility for quickly and accurately measuring DT., (© 2017 Wiley Periodicals, Inc.)

Objective: Exposure and response prevention (ERP) is an effective treatment for individuals with obsessive-compulsive disorder (OCD), yet a substantial number of individuals with OCD do not fully respond to this intervention. Based on emerging experimental and clinical research on acceptance, this study sought to explore whether willingness to experience unpleasant thoughts, emotions, and bodily sensations during ERP was associated with improved treatment response., Methods: Two hundred eighty-eight adults with OCD receiving residential ERP provided self-rated willingness and other exposure-related variables during each daily coached ERP session. Obsessive-compulsive and depressive symptom severity was assessed every week. Multilevel modeling was used to study the impact of willingness on treatment outcome during the first 6 weeks of residential care., Results: Data indicated that individuals with higher willingness during ERP reported faster symptom reduction during residential treatment, even when controlling for length of stay, psychopharmacological intervention, depression, adherence, and rituals performed during ERP. These results appear to have both statistical and clinical significance., Conclusions: Willingness to fully experience unpleasant and unwanted thoughts, emotions, and bodily sensations during exposures appears to be a marker of successful exposure therapy in adults with OCD. Future research should examine how willingness may enhance extinction learning during ERP., (© 2017 Wiley Periodicals, Inc.)
