The objective of this study is to assess the validity of the German version of the Children's Eating Attitudes Test (ChEAT), an internationally used tool for the detection of eating disorder (ED) symptoms, in a clinical sample.
The ChEAT self-report questionnaire, comprising 26 items, was employed to examine eating behaviors of a clinical sample of 342 adolescents (aged 12-18 years) undergoing inpatient treatment at a child and adolescent psychiatric clinic in Germany. The ChEAT was validated through an exploratory factor analysis (EFA), followed by a confirmatory factor analysis (CFA) and an examination of internal consistency. Subsequent analyses were conducted to identify differences associated with participant characteristics, including age, gender, body mass index (BMI), and diagnosis. Furthermore, additional eating behaviors, depression, and anxiety symptoms were documented via supplementary questionnaires and correlated to the ChEAT to evaluate the convergent and discriminant validity.
The factorial validity of the ChEAT was confirmed through EFA and CFA, resulting in a five-factor structure with the following dimensions: 'Body and Weight Concern,' 'Dieting,' 'Social Pressure,' 'Purging and Binge Eating,' and 'Food Preoccupation'. The 24-item model showed high internal consistency and demonstrated an acceptable fit to the data. Convergent and discriminant validity of the ChEAT was supported by significant correlations with other self-report questionnaires. Higher ChEAT average scores were observed in females and those with a history of eating or depressive disorders, whereas age or BMI showed no correlation.
The data demonstrate that the German version of the ChEAT appears to be a reliable and valid instrument for identifying ED symptoms in clinical samples. However, further studies are necessary to evaluate the factor structure and validity.

本研究旨在评估国际上用于检测饮食失调（ED）症状的工具——儿童饮食态度测试（ChEAT）德语版在临床样本中的有效性。
采用包含26个条目的ChEAT自填问卷，对德国一家儿童和青少年精神病诊所接受住院治疗的342名青少年（年龄12 - 18岁）的临床样本的饮食行为进行检测。通过探索性因子分析（EFA）对ChEAT进行验证，随后进行验证性因子分析（CFA）并检验内部一致性。进行后续分析以确定与参与者特征（包括年龄、性别、体重指数（BMI）和诊断）相关的差异。此外，通过补充问卷记录额外的饮食行为、抑郁和焦虑症状，并与ChEAT进行相关性分析，以评估其收敛效度和区分效度。
通过EFA和CFA证实了ChEAT的因子效度，得出一个五因子结构，维度如下：“身体和体重关注”、“节食”、“社会压力”、“清除和暴饮暴食”以及“食物专注”。24项模型显示出高内部一致性，并与数据拟合良好。ChEAT与其他自填问卷的显著相关性支持了其收敛效度和区分效度。在女性以及有饮食或抑郁障碍病史的人群中观察到较高的ChEAT平均得分，而年龄或BMI与之无相关性。
数据表明，ChEAT德语版似乎是一种可靠且有效的工具，可用于识别临床样本中的ED症状。然而需要进一步研究来评估其因子结构和效度。
