Abstract

Image-based sexual abuse (IBSA) is a growing global issue with significant psychological impacts, yet few validated tools assess childhood experiences. This study provides information on a newly developed IBSA Scale designed to capture the accumulating burden of multiple distinct dimensions of IBSA. The study included 6226 U.S. participants aged 18-28, with an oversampling of IBSA experiences (prior to age of 18) and of sexual and gender minority individuals. Psychometric evaluation involved Exploratory Graph Analysis (EGA) and Confirmatory Factor Analysis (CFA) were conducted to assess the scale's structure. Convergent validity was tested using peer norms and online risky behaviors, and discriminant validity with social connectedness. EGA confirmed a cohesive structure and 100% stability of all items, confirmed by CFA (χ²(9) = 102.17, p < .01, CFI = .99, RMSEA = .041). Convergent validity was demonstrated by moderate correlations with peer norms (rmean = .41) and online risky behaviors (rmean = .24). Discriminant validity was confirmed with low correlations with social connectedness (rmean = -.06). Sociodemographic analysis revealed higher IBSA scores among females, sexual and gender minority individuals, and participants with lower-income (p < .001). The IBSA scale is a promising tool for measuring the cumulative burden of different IBSA experiences.

基于图像的性侵犯（IBSA）测量：IBSA量表的心理计量学验证与分析。

基于图像的性虐待（IBSA）是一个日益严重的全球性问题，具有重大的心理影响，但很少有有效的工具来评估儿童经历。本研究为新开发的IBSA量表提供了信息，该量表旨在捕捉IBSA多个不同维度的累积负担。该研究包括6226名年龄在18-28岁之间的美国参与者，对IBSA经历（18岁之前）和性少数群体进行了过采样。采用探索性图分析（Exploratory Graph Analysis， EGA）和验证性因子分析（Confirmatory Factor Analysis， CFA）进行心理测量量表的结构评估。用同伴规范和网络风险行为测试收敛效度，用社会连通性测试区别效度。EGA证实所有项目具有内聚结构和100%的稳定性，经CFA证实（χ2(9) = 102.17, p < 0.01, CFI = 0.99, RMSEA = 0.041）。趋同效度与同伴规范（rmean = 0.41）和网络风险行为（rmean = 0.24）有中等相关性。判别效度与社会连通性的相关性较低（rmean = - 0.06）。社会人口学分析显示，女性、性少数和性别少数个体以及低收入参与者的IBSA得分较高（p < .001）。IBSA量表是衡量不同IBSA经验累积负担的一个很有前途的工具。
