Weight stigma is pervasive, and it has a significant impact on the social, physical, and psychological health of an individual. Weight stigma is observed from several different sources. Therefore, the present study developed and validated a new instrument, the Weight Stigma Exposure Inventory (WeSEI), to assess different sources of observed weight stigma across interpersonal and non-interpersonal sources.
The participants (n = 15,991) comprised Taiwanese young adults, Chinese adolescents, and Chinese young adults who completed paper-and-pencil and online surveys between September 2023 and December 2023. All participants provided demographic information, and completed the WeSEI, Weight Self-Stigma Questionnaire (WSSQ), and Perceived Weight Stigmatization Scale (PWSS). Exploratory factor analysis (EFA) and confirmatory factor analysis (CFA) were used to examine the factor structure of the WeSEI.
EFA and CFA results confirmed a seven-factor structure (television sources, traditional media sources, social media sources, parent sources, stranger sources, significant other sources, and friends sources) across 35 items of the WeSEI. Moreover, the WeSEI was supported by measurement invariance across subgroups (i.e., subsamples, gender, and weight status). Moreover, there were positive correlations between all seven factors of the WeSEI and the WSSQ and PWSS.
The WeSEI appears to assess observed weight stigma from different sources, and had good reliability, validity, and invariance across various subsamples. The WeSEI may be useful in clinical practice and research for assessing exposure to weight stigma from different sources.
体重歧视普遍存在，对个体的社会、身体和心理健康产生重大影响。体重歧视可从多个不同来源观察到。因此，本研究开发并验证了一种新工具——体重歧视暴露量表（WeSEI），以评估人际和非人际来源中观察到的不同体重歧视来源。
参与者（n = 15991）包括台湾年轻人、中国青少年和中国年轻人，他们在2023年9月至2023年12月期间完成了纸笔和在线调查。所有参与者提供了人口统计学信息，并完成了WeSEI、体重自我歧视问卷（WSSQ）和感知体重歧视量表（PWSS）。探索性因素分析（EFA）和验证性因素分析（CFA）用于检验WeSEI的因素结构。
EFA和CFA结果证实了WeSEI的35个项目具有七因素结构（电视来源、传统媒体来源、社交媒体来源、父母来源、陌生人来源、重要他人来源和朋友来源）。此外，WeSEI在各亚组（即子样本、性别和体重状况）中具有测量不变性。此外，WeSEI的所有七个因素与WSSQ和PWSS之间均呈正相关。
WeSEI似乎可以评估不同来源观察到的体重歧视，并且在各个子样本中具有良好的信度、效度和不变性。WeSEI在临床实践和研究中可能有助于评估来自不同来源的体重歧视暴露情况。
