Weight stigma internalization among adolescents across weight categories leads to adverse psychological consequences. This study aims to adapt and validate a Chinese version of the Weight Bias Internalization Scale for Mainland Chinese children and adolescents(C-WBIS). A total of 464 individuals aged 9 to 15 years participated in the present study. Based on item response theory (IRT) and classical test theory (CTT), we selected the items for the C-WBIS and evaluated its reliability and validity. The item response theory yields support for the one-dimensional factor mode. All item parameters fit the IRT model (albeit within an adequate range), eight items were adopted. No evidence of significant differential item functioning (DIF) was found for gender and age groups. The C-WBIS was correlated with the Core Self-Evaluation Scale (CSES) and two subscales of the Social Anxiety Scale for Children (SAS), which indicated an acceptable criterion-related validity. The C-WBIS is a reliable and valid measure that can be used as a psychometrically sound and informative tool to assess weight bias internalization among children and adolescents.
不同体重类别的青少年内化体重污名会导致不良的心理后果。本研究旨在对中国大陆儿童和青少年的体重偏见内化量表（C-WBIS）中文版进行改编和验证。共有464名9至15岁的个体参与了本研究。基于项目反应理论（IRT）和经典测验理论（CTT），我们选择了C-WBIS的项目并评估了其信度和效度。项目反应理论支持单维因素模型。所有项目参数均符合IRT模型（尽管在适当范围内），采用了8个项目。未发现性别和年龄组存在显著的项目功能差异（DIF）证据。C-WBIS与核心自我评价量表（CSES）以及儿童社交焦虑量表（SAS）的两个子量表相关，这表明其具有可接受的效标关联效度。C-WBIS是一种可靠且有效的测量工具，可作为一种心理测量学上合理且信息丰富的工具，用于评估儿童和青少年的体重偏见内化情况。
