This study aimed to develop and validate a Chinese version of the Weight-Related Eating Behavior Questionnaire (WREQ-C) for assessing dietary restraint, emotional eating, and external eating, demonstrating good reliability and validity for assessing the psychological aspects of eating behavior in Chinese adults.
Valid and reliable measures are needed to identify individuals at risk of dietary restraint, emotional and external eating, and to customize weight loss education for more effective weight management. This study aimed to develop and validate a Chinese version of the Weight-Related Eating Behavior Questionnaire (WREQ-C) for assessing dietary restraint, emotional eating, and external eating. In stage one, the linguistic validation of the original English version of the WREQ (WREQ-E) was conducted. In stage two, the psychometric properties of the WREQ-C were first evaluated by item response theory-based (IRT) analyses. The reduced scale was then examined for convergent validity, structural validity (using a confirmatory factor analysis), population invariance, and test-retest reliability. The study included 1007 adults aged between 18 and 71 years. The IRT analysis optimally shortened the original WREQ-E from 16 to 13 items. A convergent validity analysis showed significant correlations between the WREQ-C subscales and the Chinese version of the Dutch Eating Behavior Questionnaire subscales (r = 0.63-0.82). The 13-item WREQ-C demonstrated good reliability (Cronbach's alpha = 0.74-0.89) and validity for assessing the psychological aspects of eating behavior, including routine restraint, compensatory restraint, susceptibility to external cues, and emotional eating in Chinese adults.
