本研究评估了包含 16 项、四因素的体重相关饮食问卷 (WREQ)，该问卷评估不同非临床亚组的饮食行为的基于理论的方面。夏威夷大学马诺阿分校普通教育班和夏威夷居民在线调查小组招募了 621 名年龄 18-81 岁 (34.3 ± 16.4) 的男性和女性，平均 BMI 为 25.7 ± 6.1 kg/m2（范围 15.5-74.1 kg/m2），以完成一项基于网络的调查。参与者主要是白人 (23%)、亚洲人/亚洲混血人 (42%) 或夏威夷原住民/太平洋岛民 (18%)。通过对整个样本进行验证性因子分析 (CFA) 以及体重状况、性别、年龄和种族，成功复制了 WREQ 的因子结构，具有很强的内部一致性。各分量表的 4 周重测信度 (n = 31) 非常出色，组间相关性为 0.849–0.932。总体不变性检验证实了 WREQ 在所有亚组中的普遍性，但没有提供证据表明各组之间的因子结构、因子载荷或指标截距存在显着差异。多变量回归分析显示，情绪化饮食与BMI（β = 0.272，P < 0.001）以及年轻人（β = 0.152，P = 0.042）和成人（β = 0.217，P = 0.001）的中长期体重变化率（体重增加）独立相关。补偿性约束与成人体重增加呈负相关（β = -0.133，P = 0.039）。节食者中日常克制和情绪化饮食的比例最高。在考虑了性别、年龄和种族后，所有关联仍然显着。假设的 WREQ 测量模型表现出非常好的结构效度，证实了 WREQ 测量在性别、年龄、种族和 BMI 亚组中的无偏普遍性，以及关于当前 BMI、体重变化和体重控制状态的出色标准相关效度。
This study evaluates the 16-item, four-factor Weight-Related Eating Questionnaire (WREQ), which assesses theory-based aspects of eating behavior, across diverse, nonclinical subgroups. A total of 621 men and women aged 18–81 years (34.3 ± 16.4) with a mean BMI of 25.7 ± 6.1 kg/m2 (range 15.5–74.1 kg/m2) were recruited from general education classes at the University of Hawai’i, Manoa and an online survey panel of Hawai’i residents to complete a web-based survey. Participants were predominantly white (23%), Asian/Asian-mix (42%), or Native Hawaiian/Pacific Islander (18%). The WREQ’s factor structure was successfully replicated by confirmatory factor analysis (CFA) for the entire sample and by weight status, gender, age, and race with strong internal consistency. Four-week test–retest reliability (n = 31) for the subscales was excellent with interclass correlations of 0.849–0.932. Tests of population invariance confirmed the generalizability of the WREQ across all subgroups having provided no evidence that the factor structure, factor loadings, or indicator intercepts varied significantly between the groups. Multivariate regression analyses showed that emotional eating was independently associated with BMI (β = 0.272, P < 0.001) as well as moderate- and long-term weight change rates (weight gain) in young adults (β = 0.152, P = 0.042) and adults (β = 0.217, P = 0.001). Compensatory restraint was negatively associated with weight gain in adults (β = −0.133, P = 0.039). Routine restraint and emotional eating were highest among dieters. All associations remained significant after accounting for gender, age, and race. The hypothesized WREQ measurement model demonstrated very good construct validity, confirming the unbiased generalizability of the WREQ measure across sex, age, race, and BMI subgroups, and excellent criterion-related validity with respect to current BMI, weight change, and weight control status.
