ABSTRACT

Although the quantity of pornography use (QPU, i.e., frequency/time spent on pornography use) has been positively associated with the severity of pornography use (i.e., problematic pornography use, PPU), the magnitudes of relationships have varied across studies. This meta-analysis aimed to assess the overall relationships and identify potential moderating variables to explain the variation in these associations between QPU and PPU. We performed a literature search for all published and unpublished studies from 1995 to 2020 in major online scientific databases up until December 2020. Sixty-one studies were identified with 82 independent samples involving 74,880 participants. Results indicated that there was a positive, moderate relationship between QPU and PPU (r = 0.34, p < .001). The strength of relationship significantly varied across measures of PPU based on different theoretical frameworks, indicators of QPU, and sexual cultural contexts (conservative vs. permissive sexual values). Frequency was a more robust quantitative indicator of PPU than time spent on pornography use. In conservative countries, QPU showed more robust association with self-perceived PPU. Future studies are encouraged to select the measurement of PPU according to research aims and use multi-item measures with demonstrated content validity to assess pornography use. Cross-cultural (conservative/permissive) comparisons also warrant further research.

摘要

尽管色情使用的数量（QPU，即色情使用的频率/时间）与色情使用的严重程度（即有问题的色情使用，PPU）呈正相关，但关系的大小因研究而异。该荟萃分析旨在评估整体关系并确定潜在的调节变量，以解释 QPU 和 PPU 之间这些关联的变化。我们对截至 2020 年 12 月的主要在线科学数据库中 1995 年至 2020 年所有已发表和未发表的研究进行了文献检索。确定了 61 项研究，包括 82 个独立样本，涉及 74,880 名参与者。结果表明，QPU 和 PPU 之间存在正、中度关系（r = 0.34，p< .001)。基于不同的理论框架、QPU 指标和性文化背景（保守与宽容的性价值观），PPU 测量的关系强度显着不同。与花在色情使用上的时间相比，频率是 PPU 更可靠的定量指标。在保守的国家，QPU 与自我感知的 PPU 表现出更强的关联。鼓励未来的研究根据研究目标选择 PPU 的测量方法，并使用具有证明内容有效性的多项目测量来评估色情使用。跨文化（保守/宽容）比较也值得进一步研究。
