The Development and Validation of the Pornography Use in Romantic Relationships Scale.

Recent reviews of the pornography literature have called for the development of valid and reliable measures that assess multiple facets of pornography use. Moreover, despite pornography use having important implications for romantic relationships, there are currently no self-report assessments of pornography use specifically within the context of romantic relationships. To address these limitations, the current paper reports on two studies regarding the development and psychometric evaluation of a 38-item multidimensional measure of pornography use within the context of romantic relationships: the Pornography Use in Romantic Relationships Scale (PURRS). Study 1 (n = 739) reports on an Exploratory and Confirmatory Factor Analytic approach to determine the factor structure of the PURRS. Study 2 (n = 765) reports on the cross-validation of the factor structure of the PURRS, before assessing the criterion validity of the measure. The PURRS exhibited good internal consistency, construct validity, and criterion validity. The findings suggest that the PURRS is best modeled by 13 first-order factors, though a higher-order factor structure comprising four broad factors may also be used. The PURRS significantly extends on past assessments of pornography use, and in particular, advances the assessment and study of pornography use within the context of romantic relationships.
