A New Scrupulosity Scale for the Dimensional Obsessive-Compulsive Scale (DOCS): Validation With Clinical and Nonclinical Samples

Scrupulous obsessions are a prominent presentation of obsessive-compulsive disorder (OCD). Previous conceptualizations of scrupulosity have indicated that it belongs to the unacceptable thoughts dimension, which pertains to sexual, violent, and religious obsessive themes. However, research suggests that scrupulous symptoms may differ from other unacceptable thoughts symptoms, necessitating the need for targeted and thorough assessment. We added a Scrupulous or Religious Thoughts subscale (DOCS-SR) to the Dimensional Obsessive-Compulsive Scale (DOCS) and tested its factorial structure, psychometric properties, and clinical correlates in a nonclinical and clinical sample. In the first study, nonclinical participants (N = 203) completed the DOCS-SR, which was subjected to an exploratory factor analysis. Analyses revealed that the DOCS-SR reflected a one-factor solution and possessed acceptable internal consistency, as well as strong convergent validity with clinical correlates of OCD. In the second study, we administered the DOCS, as well as the DOCS-SR to a clinical sample (N = 314). An exploratory factor analysis and confirmatory factor analysis both suggested that the four subscales and additional DOCS-SR represented a five-factor solution. Internal consistency and convergent validity were strong. The DOCS Unacceptable Thoughts subscale and the DOCS-SR shared a moderate correlation but evidenced differences in associations with other correlates. This suggested both convergent and divergent validity. Collectively, our results support the utility of examining the individual components of the unacceptable thoughts dimension of OCD for effective assessment and treatment planning.

Disgust sensitivity mediates the link between homophobia and sexual orientation obsessive-compulsive symptoms

Previous research has shown that intrusive thoughts in obsessive-compulsive disorder (OCD) often focus on emotionally significant aspects of individuals' lives (e.g., values and beliefs). The current study sought to expand our understanding of OC symptoms related to sexual orientation (SO-OC symptoms) by investigating the roles of homophobia (i.e., negative attitudes, affect, and behaviors toward individuals with a same-gender orientation) and disgust propensity and sensitivity. A total of 592 self-identified heterosexual college students were recruited to complete measures of homophobia, disgust propensity and sensitivity, and SO-OC symptoms. Results of separate parallel mediation analyses indicated that the relationships between homophobic affect/attitudes and avoidance/aggression on one hand, and SO-OC symptoms on the other, were partially mediated specifically by disgust sensitivity, after controlling for gender. Theoretical and clinical implications are discussed, including how homophobia can be conceptualized as a disgust response in the treatment of SO-OC symptoms, as well as how other constructs of potential interest (sexual and moral disgust, religiosity, conservative sexual ideology) can be examined in future research.
