Although pornography viewing is widespread among Internet users, no scales for measuring pornography use motivations (PUM) have been developed and psychometrically tested for use in general populations. The present work aimed to construct a measure that could reliably assess a wide range of PUM in nonspecific populations. Self-report data of 3 separate samples (N₁ = 772 [51% women], N₂ = 792 [6% women], N₃ = 1,082 [50% women]) were collected and analyzed using confirmatory factor analysis, measurement invariance testing, and structural equation modeling (SEM). The most common PUM were identified based on a literature review and qualitative analysis (N₁): sexual pleasure, sexual curiosity, emotional distraction or suppression, stress reduction, fantasy, boredom avoidance, lack of sexual satisfaction, and self-exploration. Items were constructed, and confirmatory factor analyses (N₂ and N₃) yielded strong psychometric properties. Further corroborating the structural validity of the Pornography Use Motivations Scale (PUMS), gender-based measurement invariance was tested, and associations of the frequency of pornography use (FPU), problematic pornography use (PPU), and PUM were examined. Men-compared to women-demonstrated higher scores on all motivations except for sexual curiosity and self-exploration. Based on the results of SEM, we found that sexual pleasure, boredom avoidance, and stress reduction motivations showed positive, weak-to-moderate associations with FPU. Motivations relating to stress reduction, emotional distraction or suppression, boredom avoidance, fantasy, and sexual pleasure had positive, weak-to-moderate associations with PPU. The PUMS is a reliable scale to assess the most common PUM in general populations. (PsycInfo Database Record (c) 2020 APA, all rights reserved).

人们为什么观看色情内容？色情使用的动机基础。

尽管色情观看在互联网用户中十分普遍，但尚未开发出用于测量色情使用动机（PUM）的量表，并进行了心理测试以用于普通人群。当前的工作旨在构建一种可以可靠地评估非特定人群中广泛的PUM的措施。收集了三个独立样本的自我报告数据（N₁= 772 [51％的女性]，N2 = 792 [6％的女性]，N₃= 1,082 [50％的女性]），并使用验证性因子分析，测量不变性检验和结构方程模型（SEM）。根据文献回顾和定性分析（N₁）确定了最常见的PUM：性快感，性好奇，情绪分散或抑制，压力减轻，幻想，避免无聊，性满足感不足和自我探索。物品被建造，验证性因素分析（N 2和N 3）产生了很强的心理计量特性。进一步证实了“色情使用动机量表”（PUMS）的结构有效性，测试了基于性别的测量不变性，并检查了色情使用频率（FPU），有问题的色情使用（PPU）和PUM的关联。与男性相比，除性好奇心和自我探索能力外，男性在所有动机上的得分均较高。根据SEM的结果，我们发现性快感，避免无聊和减轻压力的动机与FPU表现出积极的，弱到中度的联系。与减轻压力，分心或抑制情绪，避免无聊，幻想和性快感有关的动机与PPU有积极，弱到中度的联系。PUMS是评估普通人群中最常见的PUM的可靠量表。（PsycInfo数据库记录（c）2020 APA，保留所有权利）。
