本研究旨在评估20项日本版荷兰儿童饮食行为问卷（DEBQ-C）的心理测量学特性。以502名日本小学五年级和六年级学生以及初中一年级和二年级学生为样本，对他们进行了评估。样本被随机分为两个子样本，一个进行探索性因素分析（EFA），另一个进行验证性因素分析（CFA）。内部一致性估计的分量表（克制，情绪和外部）进行了评估，使用克朗巴赫的α。通过使用多组CFA检查每个亚组（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。日文版DEBQ-C的项目分析结果良好。EFA和CFA都支持最初DEBQ-C的三因素结构。各因素的信度也令人满意（约束：α = 0.86，情感：α = 0.90，外在：α = 0.86）。多组验证性因素分析的结果支持它的度量和标量或部分标量测量在所有亚组的不变性。在性别分组中，女孩在限制饮食方面得分更高。在学校亚组中，初中生的情绪和外食得分较高。在BMI亚组中，超重儿童在限制饮食方面得分较高。这些研究结果表明，日本版的DEBQ-C是一种心理测量学有效和可靠的工具，用于评估日本儿童的性别，学校类别和BMI类别的饮食行为。
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: alpha = 0.86, emotional: alpha = 0.90, external: alpha = 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.
