During a one-year weight loss trial, we compared the Three-Factor Eating Questionnaire (TFEQ), a valid 51-item measure of restraint, disinhibition, and hunger subscales, with the newer 16-item Weight-Related Eating Questionnaire (WREQ) measuring routine and compensatory restraint and external and emotional eating.
Both questionnaires were administered to women with overweight or obesity (n = 186, mean ± SD, age 50 ± 10.6 y, BMI 34 ± 4.2 kg/m) at five time points. Completion rates were 100% at baseline and Month 1, 94% at Month 3, 83% at Month 6, and 76% at Month 12. Confirmatory factor analysis was conducted on baseline WREQ data and correlations were calculated between TFEQ and WREQ subscales. Multilevel models evaluated the relationship between each subscale and weight change over time.
Factor analysis revealed a WREQ structure consistent with previous research, and corresponding subscales on the TFEQ and WREQ were correlated. Lower baseline TFEQ restraint predicted greater weight loss. Across five administrations, TFEQ and WREQ restraint scores were positively related to weight loss (p < 0.01) and TFEQ disinhibition and WREQ external and emotional eating scores were negatively related (p < 0.001). Thus, with one baseline administration, only TFEQ restraint was significantly related to weight change, but multiple administrations showed relationships between all TFEQ and WREQ subscales and weight change.
The WREQ offers a shorter alternative to the TFEQ when repeatedly assessing eating behaviors related to weight change.
在一项为期一年的减肥试验中，我们将三因素饮食问卷（TFEQ，一种有效的、包含51个条目的测量节制、去抑制和饥饿分量表的工具）与更新的、包含16个条目的体重相关饮食问卷（WREQ，用于测量常规和代偿性节制以及外在和情绪性进食）进行了比较。
在五个时间点，对超重或肥胖女性（n = 186，均值±标准差，年龄50±10.6岁，体重指数34±4.2kg/m²）同时发放这两种问卷。基线和第1个月的完成率为100%，第3个月为94%，第6个月为83%，第12个月为76%。对基线WREQ数据进行验证性因素分析，并计算TFEQ与WREQ各分量表之间的相关性。多水平模型评估了每个分量表与随时间变化的体重之间的关系。
因素分析显示WREQ的结构与先前研究一致，并且TFEQ和WREQ上相应的分量表存在相关性。较低的基线TFEQ节制得分预示着更大的体重减轻。在五次问卷发放中，TFEQ和WREQ的节制得分与体重减轻呈正相关（p < 0.01），而TFEQ的去抑制得分与WREQ的外在和情绪性进食得分呈负相关（p < 0.001）。因此，仅一次基线测量时，只有TFEQ节制与体重变化显著相关，但多次测量显示所有TFEQ和WREQ分量表与体重变化之间均存在关联。
在反复评估与体重变化相关的饮食行为时，WREQ为TFEQ提供了一个更简短的替代方案。
