“…However, the authors note that they used a nonrepresentative sample of severe, potentially treatment resistant inpatients, which can bias ROC analysis results and lead to inaccurate cut-score suggestions. Moreover, Shapiro et al (2013) did not have information regarding patients’ religious affiliation or the reliability of OCD subtypes. Given the potential for using the PIOS as a screening measure, an examination of its factor structure and concurrent validity in an outpatient clinical sample is important.…”

“…Given the potential for using the PIOS as a screening measure, an examination of its factor structure and concurrent validity in an outpatient clinical sample is important. Indeed, the studies by Nelson et al (2006) and Shapiro et al (2013) were notable in that they examined some psychometric properties of the PIOS or PIOS-R in clinical OCD samples.…”

“…A second study (Shapiro, Krompinger, Gironda, & Elias, 2013) examined the factor structure and concurrent validity of a shortened version of the PIOS (PIOS-R, Olatunji et al, 2007) in a sample of treatment-resistant OCD patients treated at a residential facility. Using confirmatory factor analysis, the authors reported that a two-factor structure had a better fit then a one-factor solution.…”

Scrupulosity, or obsessive-compulsive symptoms related to religiosity or religion, is a common presentation of obsessive compulsive disorder (OCD), and it is important to elucidate its phenomenology and measurement. Today, the most widespread questionnaire for the assessment of scrupulosity is the Penn Inventory of Scrupulosity (PIOS). The current study examines the psychometric properties of the PIOS in outpatient, treatment-seeking patients. Results of a confirmatory factor analysis suggested an unsatisfactory fit for previously suggested factor structures. A follow-up exploratory factor analysis suggested that a bifactor model was the most suitable solution. In addition, the scores of the PIOS and its revised subscales were found to have moderate-good concurrent validity; however, its scores discriminated poorly between patients with scrupulous obsessions and patients with OCD and other repugnant obsessions. Group differences and receiver operating characteristics (ROC) analyses both indicated that the PIOS is more suitable in discriminating scrupulous obsessions in Christian patients but not in other religious groups (i.e., Jews, nonreligious patients). Additional analyses revealed that the co-occurrence of scrupulous and other repugnant obsessions is also moderated by religious affiliation. These results raise questions in terms of grouping scrupulosity with other repugnant obsessions and suggest for the need of culturally sensitive instruments of scrupulosity.

Fear of sin and fear of God: Scrupulosity predicts women's daily experiences of mental contamination following sexual trauma

Mental contamination refers to feelings of dirtiness in response to thoughts, images, or memories. Mental contamination is frequently reported after sexual trauma and is associated with symptoms of posttraumatic stress disorder (PTSD). Differences in individuals’ views about morality and purity may influence the severity of mental contamination, though this has been studied primarily outside of samples assessed for trauma and/or PTSD. The present study addressed this gap by investigating scrupulosity as a prospective predictor of daily sexual trauma–related mental contamination and PTSD symptoms. Participants included 40 adult women with a history of sexual trauma and current sexual trauma–related mental contamination who completed baseline diagnostic interviews and questionnaires followed by two assessments every day for 2 weeks. The results indicate that scrupulosity was positively correlated with PTSD symptom severity and sexual trauma–related mental contamination at baseline. Scrupulosity was also a prospective predictor of increased daily sexual trauma–related mental contamination, B = 0.19, SE = 0.07, p = .010, but not daily PTSD symptoms, B = −0.10, SE = .08, p = .198. The findings indicate that scrupulosity may be an important factor in understanding recovery from sexual assault.
