This study aimed to evaluate the psychometric properties of the 20-item Japanese version of the Dutch Eating Behavior Questionnaire for Children (DEBQ-C). A population-based sample of 502 Japanese school children who were fifth- and sixth-graders in elementary schools and first- and second-graders in junior high schools was assessed. A sample was randomly split into two subsamples, one for exploratory factor analysis (EFA) and another for confirmatory factor analysis (CFA). Internal consistency estimates for subscales (restrained, emotional, and external) were evaluated using Cronbach's alpha. Measurement invariance was examined across each subgroup (genders: boys and girls, school categories: elementary school and junior high school, body mass index (BMI) categories: underweight, normal weight, and overweight) by using multi-group CFA. The Japanese version of the DEBQ-C demonstrates good results of item analysis. The three-factor structure of the original DEBQ-C was supported by both EFA and CFA. The reliability of each factor was also satisfied (restrained: α = 0.86, emotional: α = 0.90, external: α = 0.86). Results of multi-group confirmatory factor analysis supported its metric and scalar or partial scalar measurement invariance across all subgroups. In gender subgroup, girls scored higher on restrained eating. In school subgroup, junior high school children scored higher on emotional and external eating. In BMI subgroup, overweight children scored higher on restrained eating. These findings suggest that the Japanese version of the DEBQ-C is a psychometrically valid and reliable instrument for assessing eating behaviors across gender, school categories, and BMI categories in Japanese children.
本研究旨在评估 20 项日本版荷兰饮食行为问卷儿童版（DEBQ-C）的心理测量特性。评估了一个基于人群的 502 名日本学龄儿童样本，他们是小学五年级和六年级以及初中一年级和二年级的学生。随机将样本分为两个子样本，一个用于探索性因素分析（EFA），另一个用于验证性因素分析（CFA）。使用 Cronbach's alpha 评估分量表（约束、情绪和外部）的内部一致性估计。通过多组 CFA 检查了每个亚组（性别：男孩和女孩、学校类别：小学和初中、体重指数（BMI）类别：体重不足、正常体重和超重）的测量不变性。日本版 DEBQ-C 的项目分析结果良好。原始 DEBQ-C 的三因素结构得到了 EFA 和 CFA 的支持。每个因素的可靠性也得到了满足（约束：α=0.86，情绪：α=0.90，外部：α=0.86）。多组验证性因素分析的结果支持其在所有亚组中的度量和标度或部分标度测量不变性。在性别亚组中，女孩在约束性进食方面的得分更高。在学校亚组中，初中生在情绪和外部进食方面的得分更高。在 BMI 亚组中，超重儿童在约束性进食方面的得分更高。这些发现表明，日本版 DEBQ-C 是一种具有心理测量效度和可靠性的工具，可用于评估日本儿童在性别、学校类别和 BMI 类别之间的饮食行为。
