Eating Disorder-15 (ED-15) is a self-report scale recommended for use to evaluate weekly progress and treatment results in eating disorders. This research aims to examine the factor structure, psychometric properties, validity, and reliability of the Turkish version of ED-15 (ED-15-TR) for clinical and non-clinical samples.
Translation-back translation method was used for language equivalence of ED-15-TR. The research was conducted with a total of 1049 volunteers, with two sample groups as non-clinical (n=978) and clinical (n=71). The participants completed an information form, ED-15-TR, Eating Disorder Examination Scale (EDE-Q), and Beck Depression Inventory (BDI). Three hundred fifty-two participants from the non-clinical group and 18 from the clinical group completed ED-15-TR again within a week.
Factor analysis confirmed the two-factor structure of ED-15- TR. Cronbach's alpha value was 0.911 (0.773, and 0.904 for the two subscales respectively), the intraclass correlation coefficient for testretest reliability was 0.943 in the clinical group (0.906, and 0.942 for the two subscales respectively); 0.777 (0.699, and 0.776 for the two subscales respectively) in the non-clinical group (for all p<0.001). The high level of a positive correlation between ED-15-TR and EDE-Q supported concurrent validity.
This research indicates that ED-15-TR is an acceptable, valid, and reliable self-report scale for Turkish society.
饮食障碍-15 （ED-15）是一种自我报告量表，推荐用于评估饮食障碍的每周进展和治疗结果。本研究旨在检验 ED-15-TR（ED-15-TR）在临床和非临床样本中的因子结构、心理测量特性、有效性和可靠性。
采用翻译-回译法对 ED-15-TR 进行语言等效性检验。该研究共纳入 1049 名志愿者，分为两个样本组：非临床组（n=978）和临床组（n=71）。参与者完成了一份信息表、ED-15-TR、饮食障碍检查量表（EDE-Q）和贝克抑郁量表（BDI）。非临床组中有 352 名参与者和临床组中有 18 名参与者在一周内再次完成了 ED-15-TR。
因子分析证实了 ED-15-TR 的两因素结构。Cronbach's alpha 值为 0.911（两个子量表分别为 0.773 和 0.904），临床组的重测信度的组内相关系数为 0.943（两个子量表分别为 0.906 和 0.942）；非临床组为 0.777（两个子量表分别为 0.699 和 0.776）（所有 p<0.001）。ED-15-TR 与 EDE-Q 之间高度的正相关支持了同时效度。
本研究表明 ED-15-TR 是一种可接受、有效和可靠的土耳其语自报量表。
