Abstract

Objective: The Eating Attitudes Test-26 (EAT-26) is considered the screening instrument of choice to identify eating disorders (ED) symptoms in clinical and community populations, showing a classical three-factor structure. This study assessed whether the factor structure of the EAT-26 in patients with ED was stable at admission and discharge from inpatient treatment.

Methods: We administered the EAT-26 to 207 female adolescents with ED at both admission and discharge.

Results: Factor structure of the EAT-26 at admission comprised of four factors and at discharge three factors and 15-item version of the EAT, producing two factors, was considerably more stable at both admission and discharge. Cutoff score of 23 in the EAT-15 better defined patients as improved at discharge than the cutoff score of 20 in the EAT-26.

Conclusion: Different factor structures of the EAT are found in the same population of young females with ED during the acute stage of illness vs. symptomatic improvement. In addition, shorter versions of the EAT with higher cutoff scores may better differentiate between improved and not improved patients at discharge. Findings suggest that using the EAT-15 is more effective for evaluating a population with clinical characteristics of ED.

青春期女性进食障碍患者治疗前后饮食态度测试-26因子结构的差异
目的:饮食态度测试26 (EAT-26)被认为是临床和社区人群中识别饮食失调(ED)症状的首选筛查工具,表现出经典的三因素结构。本研究评估ED患者在入院和出院时EAT-26因子结构是否稳定。方法:我们对207名女性青少年ED患者在入院和出院时进行EAT-26测试。结果:入院时的EAT-26因子结构由4个因子组成,出院时的EAT因子结构由3个因子和15个条目组成,产生2个因子,在入院和出院时都更加稳定。EAT-15的临界值为23比EAT-26的临界值为20更好地定义了患者出院时的改善。结论:在相同的年轻女性ED患者中,在疾病的急性期和症状改善期间,发现了不同的EAT因子结构。此外,较短版本的EAT具有较高的截止分数,可以更好地区分出院时改善和未改善的患者。研究结果表明,使用EAT-15评估具有ED临床特征的人群更有效。

期刊介绍: Journal of Eating Disorders is the first open access, peer-reviewed journal publishing leading research in the science and clinical practice of eating disorders. It disseminates research that provides answers to the important issues and key challenges in the field of eating disorders and to facilitate translation of evidence into practice. The journal publishes research on all aspects of eating disorders namely their epidemiology, nature, determinants, neurobiology, prevention, treatment and outcomes. The scope includes, but is not limited to anorexia nervosa, bulimia nervosa, binge eating disorder and other eating disorders. Related areas such as important co-morbidities, obesity, body image, appetite, food and eating are also included. Articles about research methodology and assessment are welcomed where they advance the field of eating disorders.
