Prior research is equivocal concerning the relationships between religious involvement and obsessive-compulsive disorder (OCD). The literature indicates limited evidence of denomination differences in prevalence of OCD whereas findings regarding OCD and degree of religiosity are equivocal. This study builds on prior research by examining OCD in relation to diverse measures of religious involvement within the National Survey of American Life, a nationally representative sample of African American and Black Caribbean adults.Bivariate and multivariate analyses (logistic regression) examine the relationship between lifetime prevalence of OCD and religious denomination, service attendance, non-organizational religiosity (e.g., prayer, religious media) subjective religiosity, and religious coping. Frequent religious service attendance was negatively associated with OCD, whereas Catholic affiliation (as compared to Baptist) and religious coping (prayer when dealing with stressful situations) were both positively associated with OCD. With regard to demographic factors, persons of older age and higher education levels were significantly less likely to have OCD.
