Psychometric Properties of the Persian Short Version of the Problematic Pornography Consumption Scale (PPCS-6)

ABSTRACT

The short version of the Problematic Pornography Consumption Scale (PPCS-6) is a valid and reliable scale for assessing problematic pornography use. However, due to the lack of a single definition and gold standard assessment for problematic pornography use, a valid multilingual instrument can help establish standard diagnostic criteria. This cross-sectional study enrolled 115 randomly selected men and women who filled out an online questionnaire in 2021. After translating and back-translating the questionnaire, we assessed face, content, construct validity, and reliability. The results indicated excellent face validity (impact score >1.5 for every item on the questionnaire), content validity (S-CVI/Ave = 0.95 and I-CV = 0.89–1 for all the items using the K* method) and construct validity (KMO = 0.67, Sig = p < 0.001). The construct validity results indicated that the PPCS-6 included two factors in the Iranian population. The scale also had excellent reliability (Cronbach's alpha = 0.97, intra-cluster correlation coefficients = 0.97, 95%CI (0.92–0.98)(. Due to the acceptable validity and reliability of the Persian version of PPCS-6, this scale can be used in large-scale studies where several instruments are employed, and there is often a time limitation. The psychometric examination of this instrument can contribute to achieving a unified concept and assessment of problematic pornography use.
