The aim of this research was to analyze the psychometric properties of the Problematic Pornography Use Scale (PPUS).
A sample of 704 Peruvian youth and adults aged 18 to 62 years (M = 26, SD = 6.0) was considered, of which 56% were female and 43% male. The participants were from various cities in Peru: Lima (84%), Trujillo (2.6%), Arequipa (1.8%), and Huancayo (1.6%). The validity of the theoretical structure of the PPUS was carried out by means of two techniques: Confirmatory factor analysis (CFA) and Exploratory Graphical Analysis (EGA), a new effective and efficient dimension evaluation technique, whose measure consists of verifying the fit of the dimension structure.
Using the bifactor model, the hypothesis that PPUS has a unifactorial behavior was corroborated. These approximations of unidimensionality are also corroborated by the EGA method, where the centrality parameters and network loadings are found to have acceptable estimates.
The results demonstrate the validity of the PPUS, contrasting with the factor model and verifying the unidimensionality of the construct, which provide useful directions for future studies on the instrumentalization of problematic pornography use scale.
本研究旨在分析问题性色情使用量表（PPUS）的心理测量特性。
研究样本为704名年龄在18至62岁之间的秘鲁青年和成年人（M = 26，标准差 = 6.0），其中56%为女性，43%为男性。参与者来自秘鲁的各个城市：利马（84%）、特鲁希略（2.6%）、阿雷基帕（1.8%）和万卡约（1.6%）。PPUS理论结构的有效性通过两种技术进行验证：验证性因素分析（CFA）和探索性图形分析（EGA），后者是一种新的有效且高效的维度评估技术，其测量方法包括验证维度结构的拟合度。
采用双因素模型，证实了PPUS具有单因素行为的假设。EGA方法也证实了这些单维性的近似结果，其中中心性参数和网络负荷的估计值是可接受的。
研究结果证明了PPUS的有效性，与因素模型形成对比并验证了该结构的单维性，为未来关于问题性色情使用量表工具化的研究提供了有用的方向。
