Abstract

Background

Elite athletes experience unique pressures and cognitions associated with disordered eating, which may not be appropriately captured by existing tools. The Athletic Disordered Eating (ADE) scale is a recently developed and first measure of disordered eating specifically developed and validated in current and former athletes. This study aimed to provide further validation for the ADE in an independent sample of elite athletes.

Method

Participants were 237 elite athletes (M Age = 26.1, SDAge = 8.6; 75.9% female; 73.0% current athletes) participating in various sports across Australia and the United States. Participants completed an online survey including the ADE, demographic questions, and other measures of eating disorder symptoms (Eating Disorder Examination—Questionnaire Short-form, Clinical Impairment Assessment), and related constructs. Twenty-five athletes also completed a clinical interview to determine eating disorder caseness.

Results

The four-factor structure of the ADE from the original validation was confirmed. Further, the ADE demonstrated adequate measurement invariance across male and female current and former athletes; internal consistency for the total score and each subscale; convergent and discriminant validity; and criterion-related validity—with a score of 40 balancing sensitivity and specificity against other scales with established cut-offs for a likely eating disorder. The high-risk cut-off (ADE ≥ 33) had high sensitivity but low specificity in identifying eating disorder cases, as confirmed by the clinical interview.

Discussion

The ADE is a low-time-burden screening tool for disordered eating, validated in independent samples of diverse athletes. It should be considered for future use in screening, early identification, and monitoring treatment progress in elite athletes.

在男女优秀运动员独立样本中饮食失调测量的进一步验证:运动饮食失调量表。
背景:优秀运动员经历与饮食失调相关的独特压力和认知,这可能无法被现有工具适当捕获。运动饮食失调(ADE)量表是最近开发的,也是第一个专门针对现任和前任运动员开发和验证的饮食失调量表。本研究旨在通过独立的优秀运动员样本进一步验证ADE的有效性。方法:237名优秀运动员(MAge = 26.1, SDAge = 8.6;75.9%的女性;73.0%现在的运动员)参加澳大利亚和美国的各种运动。参与者完成了一项在线调查,包括ADE、人口统计问题、饮食失调症状的其他测量(饮食失调检查问卷简表、临床损害评估)和相关结构。25名运动员还完成了临床访谈,以确定饮食失调病例。结果:证实了原验证的ADE的四因子结构。此外,ADE在男性和女性现役和退役运动员中显示出足够的测量不变性;总分与各分量表的内部一致性;收敛效度与判别效度;与标准相关的有效性——在敏感性和特异性方面,与其他具有确定的进食障碍界限的量表进行平衡,得分为40分。临床访谈证实,高危分界点(ADE≥33)在识别进食障碍病例方面具有高敏感性,但特异性较低。讨论:ADE是一种低时间负担的饮食失调筛查工具,在不同运动员的独立样本中得到验证。应该考虑在未来用于筛选,早期识别和监测治疗进展的精英运动员。

期刊介绍: Articles featured in the journal describe state-of-the-art scientific research on theory, methodology, etiology, clinical practice, and policy related to eating disorders, as well as contributions that facilitate scholarly critique and discussion of science and practice in the field. Theoretical and empirical work on obesity or healthy eating falls within the journal’s scope inasmuch as it facilitates the advancement of efforts to describe and understand, prevent, or treat eating disorders. IJED welcomes submissions from all regions of the world and representing all levels of inquiry (including basic science, clinical trials, implementation research, and dissemination studies), and across a full range of scientific methods, disciplines, and approaches.
