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; M = 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.
迄今为止，还没有一种具有较强心理测量特性的短尺度，可以根据一个全面的理论背景来评估有问题的色情制品消费。本研究的目的是根据格里菲斯（2005）的六成分成瘾模型开发一种简短的量表，即有问题的色情制品消费量表（PPCS），该量表可以区分无问题和有问题的色情制品使用。PPCS 是使用 772 名在线受访者（390 名女性，382 名男性；M=22.56，SD=4.98 岁）的样本开发的。项目的创建基于之前的有问题的色情制品使用工具以及格里菲斯模型中因素的定义。进行了验证性因素分析（CFA），因为该量表基于一个成熟的理论模型，导致了一个 18 项二阶因子结构。PPCS 的可靠性非常好，并且建立了测量不变性。在当前的样本中，3.6%的用户属于高危人群。基于敏感性和特异性分析，我们确定了一个最佳的截止值来区分有问题和无问题的色情制品使用者。PPCS 是一种具有较强理论基础的有问题的色情制品使用多维量表，在因子结构和可靠性方面也具有较强的心理测量特性。
