Abstract

Sexual and gender minority (SGM) individuals comprise up to one fifth of obsessive-compulsive disorder (OCD) clinical samples and appear to be at greater risk for OCD than their cisgender, heterosexual peers. Recent research has examined the psychometric properties of several commonly used OCD self-report measures within an SGM sample and found them adequate to strong in terms of factor structure and loadings, internal consistency, and convergent validity. However, measurement invariance testing is needed to ensure that these measures perform similarly across individuals of diverse sexual orientations and gender identities. The present study combined data from 779 patients (15.0% SGM) presenting for OCD treatment at one of two clinical sites offering specialized treatment from outpatient through residential levels of care. The Dimensional Obsessive-Compulsive Scale, Obsessive Beliefs Questionnaire-44, and the Yale-Brown Obsessive-Compulsive Scale-Self-Report Severity Scale were subjected to confirmatory factor analyses and invariance tests across varying levels of stringency between SGM and non-SGM patients. Whereas the Dimensional Obsessive-Compulsive Scale and Obsessive Beliefs Questionnaire-44 evidenced measurement invariance, the Yale-Brown Obsessive-Compulsive Scale-Self-Report did not demonstrate configural invariance between SGM and non-SGM patients. Findings offer support for the use of the Dimensional Obsessive-Compulsive Scale and Obsessive Beliefs Questionnaire-44 in samples inclusive of diverse sexual orientations and gender identities, and recommendations for continued research in this domain are offered.
