Compulsive shopping, a behavioral disorder with significant personal and social repercussions, necessitates reliable assessment tools, especially within different cultural contexts. While several scales exist to measure compulsive buying behavior, there is a lack of validated instruments tailored to the Chinese population. This study aimed to examine the psychometric properties of the Chinese version of the Compulsive Shopping Scale (CSS) using Item Response Theory (IRT). A total of 637 young healthy participants (42.5 % males and 57.5 % females), with a mean age of 21.32 years (SD = 2.06), both undergraduate and postgraduate students, were recruited from various cities in China. Sixty-four participants were retested after a two-week interval to assess test-retest reliability. The results indicated that a one-dimensional factor structure was appropriate. The reliability analyses, including test-retest reliability, ω, α, and λ tests, demonstrated good internal consistency. The rating scale model analysis showed infit and outfit MNSQ values between 0.6 and 1.4, indicating a good fit. The item information curve and test information curve indicated a normal distribution of scores. Differential item functioning was observed in two items, suggesting potential gender-related differences. These findings indicate that the Chinese version of the CSS is a reliable and valid instrument for measuring compulsive shopping behaviors in Chinese populations.
强迫性购物是一种具有重大个人和社会影响的行为障碍，需要可靠的评估工具，特别是在不同的文化背景下。虽然有几种量表可用于衡量强迫性购买行为，但缺乏针对中国人群的经过验证的工具。本研究旨在使用项目反应理论（IRT）检验中文强迫性购物量表（CSS）的心理测量特性。共有 637 名年轻健康的参与者（42.5%为男性，57.5%为女性），平均年龄为 21.32 岁（SD=2.06），包括本科生和研究生，均来自中国的不同城市。64 名参与者在两周后进行了重测，以评估测试重测信度。结果表明，一维因子结构是合适的。可靠性分析，包括测试重测信度、ω、α和λ测试，表明具有良好的内部一致性。等级量表模型分析显示 infit 和 outfit MNSQ 值在 0.6 和 1.4 之间，表明拟合良好。项目信息曲线和测试信息曲线表明得分呈正态分布。有两个项目观察到了项目区分度差异，提示可能存在与性别相关的差异。这些发现表明，中文版本的 CSS 是一种可靠且有效的工具，可用于衡量中国人群的强迫性购物行为。
