The validation of a Spanish version of the Pennsylvania Inventory of Scrupulosity–Revised

Scrupulosity is one of the most common of the variations of obsessive-compulsive disorder (OCD). This includes obsessions and compulsions related to religiously and morality, and the Pennsylvania Inventory of Scrupulosity–Revised (PIOS-R) appears to be the only validated measure designed specifically to assess this construct. The purpose of the current study was to examine the psychometric properties of the first known Spanish version of the PIOS-R (PIOS-R-SV). In particular, the PIOS-R-SV in Spanish and its psychometric properties were examined with a sample of 361 participants from mixed religious backgrounds. Results showed good psychometric properties for the PIOS-R-SV and suggested a single-factor solution. The PIOS-R-SV was a significant predictor of OCD symptoms as measured by the Yale-Brown Obsessive-Compulsive Scale–Self-Report Version. In addition, it reported good convergent validity with the Thought-Action Fusion Scale Moral subscale and religiously assessed by the Santa Clara Strength of Religious Faith Questionnaire.
