The Science

What is the science behind our Porn Addiction Test?

Our test is based on the Problematic Pornography Consumption Scale (PPCS) created by Beáta Bőthe , István Tóth-Király, and Ágnes Zsila at the Doctoral School of Psychology, Eötvös Loránd University; and Institute of Psychology, Eötvös Loránd University.

Abstract from The Development of the Problematic Pornography Consumption Scale (PPCS):

To date, no short scale exists with strong psychometric properties that can assess problematic pornography consumption based on an overarching theoretical background. The goal of the present study was to develop a brief scale, the Problematic Pornography Consumption Scale (PPCS), based on Griffiths’s (2005) six-component addiction model that can distinguish between nonproblematic and problematic pornography use. The PPCS was developed using an online sample of 772 respondents (390 females, 382 males; Mage = 22.56, SD = 4.98 years). Creation of items was based on previous problematic pornography use instruments and on the definitions of factors in Griffiths’s model. A confirmatory factor analysis (CFA) was carried out—because the scale is based on a well-established theoretical model—leading to an 18-item second-order factor structure. The reliability of the PPCS was excellent, and measurement invariance was established. In the current sample, 3.6% of the users belonged to the at-risk group. Based on sensitivity and specificity analyses, we identified an optimal cutoff to distinguish between problematic and nonproblematic pornography users. The PPCS is a multidimensional scale of problematic pornography use with a strong theoretical basis that also has strong psychometric properties in terms of factor structure and reliability.

How did the study define pornography?

According to a relatively recent review by Short, Black, Smith, Wetterneck, and Wells (2012), 84% of the scientific research studies into pornography either did not define pornography and/or did not report whether the research had provided a definition of pornography for their participants. Hald (2006) used a definition that includes the role of pornography in the creation or enhancement of sexual feelings and thoughts while genitals and/or sexual acts are explicitly shown.
