The objectives of the present study were to (i) re-evaluate and expand the psychometric properties of two weight stigma instruments-the Perceived Weight Stigma Scale (PWSS) and the Weight Self-Stigma Questionnaire (WSSQ) among a large sample of adolescents using advanced psychometric methods and (ii) examine how the different types of weight stigma (i.e., PWSS and WSSQ) are associated with psychological distress.
Cross-sectional study.
In September 2023, a cross-sectional survey utilising convenience sampling was used to recruit 9995 adolescents (mean age = 16.36 years [standard deviation = 0.78]; 57.8% males). They completed the PWSS, WSSQ, and a measure on psychological distress. The data were analysed using Rasch analysis, confirmatory factor analysis (CFA), structural equation modelling (SEM), and network analysis.
The CFA and Rasch model results showed acceptable psychometric properties regarding factor structure, factor loading, difficulty, and infit and outfit mean squares (except Items 4 and 7 of the PWSS). There was no substantial differential item functioning for any tested items across the sex and weight categories. The CFA and SEM results showed promising validity indices with significant associations between both weight stigma scales and psychological distress (i.e., depression, anxiety, and stress). Network analysis showed inter-variable connectivity between nodes PWSS3 ("People act as if they are afraid of you") and WSSQF7 ("I feel insecure about others' opinions of me").
Both weight stigma scales had acceptable psychometric properties and were significantly associated with psychological distress, although each assessed different types of weight stigma. This suggests that researchers and clinicians can use these scales to reliably and validly assess weight stigmas among adolescents.
本研究的目的是：（i）使用先进的心理测量方法，在大量青少年样本中重新评估并扩展两种体重污名量表——感知体重污名量表（PWSS）和体重自我污名问卷（WSSQ）的心理测量特性；（ii）研究不同类型的体重污名（即PWSS和WSSQ）与心理困扰之间的关联。
横断面研究。
2023年9月，采用便利抽样的横断面调查方法招募了9995名青少年（平均年龄 = 16.36岁[标准差 = 0.78]；57.8%为男性）。他们完成了PWSS、WSSQ以及一项心理困扰测量。数据采用拉施分析、验证性因子分析（CFA）、结构方程模型（SEM）和网络分析进行分析。
CFA和拉施模型结果显示，在因子结构、因子负荷、难度以及内拟合和外拟合均方方面，心理测量特性可接受（PWSS的第4项和第7项除外）。在性别和体重类别中，任何测试项目均未发现显著的项目功能差异。CFA和SEM结果显示，效度指标良好，两种体重污名量表与心理困扰（即抑郁、焦虑和压力）之间均存在显著关联。网络分析显示，节点PWSS3（“人们表现得好像怕你”）和WSSQF7（“我对他人对我的看法感到不安全”）之间存在变量间连通性。
两种体重污名量表均具有可接受的心理测量特性，且与心理困扰显著相关，尽管每种量表评估的是不同类型的体重污名。这表明研究人员和临床医生可以使用这些量表可靠且有效地评估青少年中的体重污名。
