Two studies were used to compare the two questionnaires. Poorly fitting items were considered for deletion. Altering the response categories to a four-point rating scale, based on Rasch analysis, improved the functioning of the scale although a tendency of respondents to endorse the extreme points of the scale remained. At least 10 responses should be present in each response category. Items 13–18 of the EDE-Q elicit open responses to the frequency (number of times or days) of specific eating behaviours, such as objective binge eating (OBE), self-induced vomiting (SIV), laxative use (LAX) or excessive exercise (EX), over the last 28 days. However, a lot of change over a relatively short period was not anticipated either in the general population or in the clinical sample since they were not in treatment. Spearman’s Rho co-efficient was used for correlational analyses between the EDE-QS and the other questionnaires to establish convergent validity as the data were non-normally distributed. Rasch analysis was also used to improve the existing rating scale categories and make them more suitable for a weekly outcome measure. that responses to one item are dependent on or can be predicted by responses to another item, which implies item redundancy [33]. No, Is the Subject Area "Bulimia nervosa" applicable to this article? "You are" becomes "you're". Internal consistency as measured by Cronbach’s alpha was 0.77 for physical health, 0.73 for social relationships 0.78 for environment and 0.88 for psychological health. What does EDE-Q stand for? Given the aforementioned problems with the original EDE-Q’s response categories, it may be useful to revise them and to consider a reduction in the number of response options. Probability curves improved markedly but still showed respondents’ tendency to endorse the extreme points of the questionnaire, i.e. In addition they filled out the Short Evaluation of Eating Disorders (SEED), the SCOFF questionnaire, the Generalized Anxiety Disorder Questionnaire, the Patient Health Questionnaire, and the World Health Organization Quality of Life Questionnaire. The polytomous Rasch rating scale model was applied because the EDE-Q’s response scale is ordinal with seven response options. Cronbach’s alpha was 0.91. The ICC demonstrated a high and appropriate degree of temporal stability (ICC = 0.93; p < .001) (95% CI: 0.91, 0.94). Yes Research Department of Clinical, Educational & Health Psychology, University College London, London, United Kingdom, The rating scale diagnostics and probability curves of the collapsed models were then compared to the original to identify the optimal number of response categories [32]. The only exception was the domain of ‘environment’ in the quality of life measure as this did not show a negative association with the EDE-QS for people with eating disorders. This is a brief eating disorder assessment instrument, consisting of 13 questions from which anorexia (ANTSI) and bulimia (BNTSI) severity indices can be derived. Only the scaled EDE-Q items were included in the analyses. https://doi.org/10.1371/journal.pone.0152744.t001. There was a high consistency between the EDE-Q and the EDE-QS with regards to reporting behaviours typical of eating difficulties, i.e. Where this applied, deletion of one of the dependent items was considered. A shorter tool, if it is seen as more proportionate, is also advantageous for assessing eating disorder symptom severity in clinical settings where eating disorder may be a feature but not the primary focus, such as personality disorder or bariatric services. by AcronymAndSlang.com Gideon N, It showed very good convergent validity with the long version both, for people with and without an eating disorder. EDE-Q - Allie: Result by abbreviation A Search Service for Abbreviation / Long Form PLoS ONE 11(5): Information from the exploratory PCA, Rasch Modelling and expert survey was considered in conjunction to make decisions on the inclusion and exclusion of items. Hop on to get the meaning of EDE-Q. In 1,836 participants ages 7 to 18 years, recruited from two independent population-based samples, the factor structure of the recently established 8-item short form EDE-Q8 for adults was examined, including measurement invariance analyses on age, gender, and weight status derived from objectively measured weight and height. Cronbach’s alpha in the current study sample was 0.64. Strengths of this study included its empirical derivation from the EDE-Q and indirectly the EDE, grounding it in the extensive clinical and research bases of these measures. Rasch analysis was carried out separately on each dimension to satisfy the model’s assumption of unidimensionality [30, 31]. Twenty five of these were alerted to the study through the university email appeal and the rest through advertisement provided by the eating disorder charity. ©2016 iaedp. The second study did have some limitations, including its small sample size and convenience sampling method. The finding coincides with the developers’ validation study, which found a high correlation coefficient of .89 between the EDE-Q and the CIA [2], comparable to that obtained between the EDE-QS and the CIA and the EDE-Q and the CIA in people with and without an eating disorder in this study. Tchanturia K, However, limited data exist about test-retest reliability, particularly for men. EDE-Q means Eating Disorder Examination Questionnaire. Development and Psychometric Validation of the EDE-QS, a 12 Item Short Form of the Eating Disorder Examination Questionnaire (EDE-Q) PLOS ONE, Dec 2019 Nicole Gideon, Nick Hawkes, Jonathan Mond, Rob Saunders, Kate Tchanturia, Lucy Serpell. The aim of this study was to validate the EDE-QS, the newly developed short version of the EDE-Q. * E-mail: nicole.gideon.11@ucl.ac.uk (NG); lucy@serpell.com (LS), Affiliation The main difference was the removal of frequency questions about subjective binge eating and diuretic misuse from version 6.0. (EDE-Q) for a clinical sample of males in the United States are presented. The SEED has been found to have acceptable construct and discriminative validity [43]. Further research, however, will be needed to establish the EDE-QS’s sensitivity to change over time in different clinical settings and in different subgroups of patients. The obtained data were anonymised and de-identified prior to analysis. 6-12 days : 13-15 days 16-22 days 23-27 days . The Eating Disorder Examination-Questionnaire (EDE-Q), a widely used self-report instrument, is often used for measuring change in eating disorder symptoms over the course of treatment. PLOS ONE promises fair, rigorous peer review, We also use these short forms in informal written English. The strong correlation with the CIA was to be as expected because the CIA measures psychosocial impairment secondary to eating disorder and, therefore, should be highly correlated with eating disorder symptom severity. PLOS ONE 13(11): e0207256. Strong convergent validity between the EDE-Q and EDE has also been demonstrated in both clinical and general population samples [9, 12, 18]. Twenty-five had seen the study though the university email appeal and the rest were recruited through the Beat advertisement. This study obtained ethical approval from a National Health Service (NHS) ethics committee. This may have arisen due to differences and difficulties in calculating the exact number of days within one month on which specified experiences or behaviours occurred. The revised four-point response scale demonstrated improved category thresholds, distribution of response frequencies and probability curves across all factors (see Table 2). Due to its brevity and revised response categories, the EDE-QS lends itself to being used as a weekly measure permitting ongoing progress monitoring, which has been shown to improve patients’ outcomes [4] and is increasingly implemented in mental health settings. Recently, as "Yahweh" is likely an imperfective verb form, "Yahu" is its corresponding preterite or jussive short form : compare yiŝtahaweh (imperfective), yiŝtáhû (preterit or jussive short form ) = "do obeisance". Instead of "I am" we say, "I'm". Department of Psychology, Macquarie University, Sydney, Australia, It would be desirable to establish clinically significant change indices or cut-off points for the EDE-QS to differentiate between non-clinical and clinical impairment in eating disorders. There should be a consistent increase of average measures with each category. Further, this study was conducted within an adult population and the questionnaire’s suitability in adolescents remains yet to be investigated. The EDE-QS is a brief, reliable and valid measure of eating disorder symptom severity that performs similarly to the EDE-Q and that lends itself for the use of sessional outcome monitoring in treatment and research. The new measure showed high internal consistency (Cronbach's α = .913) and temporal stability (ICC = .93; p < .001). The SCOFF’s questions can be answered with a “yes” or “no” response. View Items 16 and 17 refer to compensatory behaviours (i.e. symptoms being present at least once per week [27]. During the EDE interview memory prompts are given by using a calendar, which may enhance recall [57]. how clinically meaningful scores or changes in score on each item are perceived to be. The new measure showed high internal consistency (Cronbach's α =.913) and temporal stability (ICC =.93; p <.001). What most visitors search for before coming to this page. Due to the questionable validity of the EDE-Q’s subscales and inconsistent results with regards to number of factors and associated items in the literature (e.g., [19, 20]), an exploratory principal component analysis (PCA) was conducted first to derive the dimensions of the EDE-Q in our sample. Mean age at time of admission was 24.4 years (SD = 12.6), mean body mass index at Correction: Development and Psychometric Validation of the EDE-QS, a 12 Item Short Form of the Eating Disorder Examination Questionnaire (EDE-Q) It consists of questions about key characteristics of anorexia and bulimia nervosa, which indicate self-induced vomiting, loss of control over eating, significant weight loss, perceived fatness and overvaluation of food. EDE-Q is a shorter form of Eating Disorder Examination Questionnaire. “no days” and “every day”. EDE-Q is an abbreviation for Eating Disorder Examination Questionnaire. Template short form Every template also has a "Short form" version. Performed the experiments: NG. RESULTS: A 12-item short form, the Eating Disorder Examination Questionnaire Short (EDE-QS) was derived. All participants were given information about the scope and aims of the study, confidentiality and data protection. Professionals from different countries (including UK, USA, Canada and Australia) were invited to participate but unfortunately the country of residence was not recorded in the survey and details in this regard are therefore not available. This was further supported by the scree plot. People who reported a current eating disorder (Mdn = 17.5) scored higher on the EDE-QS than those who did not (Mdn = 5.0; U = 3209.5, p < .001). Since the study aimed to develop a measure suitable for sessional outcome measurement, which is likely to be weekly, the response scale was recoded from a 28 day reference to seven days. https://doi.org/10.1371/journal.pone.0152744.t003. https://doi.org/10.1371/journal.pone.0152744, Editor: Nori Takei, United (Osaka U, Kanazawa U, Hamamatsu U Sch Med, Chiba U and Fukui U) Graduate School of Child Developmen, JAPAN, Received: July 20, 2015; Accepted: March 18, 2016; Published: May 3, 2016. Referring to the past week also helps to obtain more accurate diagnostic criteria, i.e. To reduce missing responses and increase simplicity of coding of the frequency items, a Likert-scale response format was adopted. High correlations between the short-form and the original EDE-Q suggest that the most relevant and informative items have been retained in the shortened version. here. 6, p. 578. The EDE-Q’s psychometric properties have been extensively investigated in various study populations, including individuals with eating disorders receiving specialist treatment. There was only a medium correlation between the EDE-QS and the SEED questionnaire. Questionnaire EDEQ abbreviation meaning defined here. For comparative purposes, correlations between both, the EDE-QS and the EDE-Q, and other study variables were conducted for both “no ED” and “current ED” subgroups. Of the 27 participants, who were given a probable diagnosis of OSFED, 24 (89%) had a global EDE-Q score of ≥ 2.3, the latter being a cut-point for ‘probable eating disorder case’ according to previous research in general population samples of young adult women [18].The majority of all respondents were aged between 18–34 years (N = 516; 92.5%) and female (N = 452; 80.9%). In spoken English we use the short form a lot. Items that showed a strong overlap of difficulty (i.e., differences <0.20) were considered for deletion [37]. Respondents rate each of seven anxiety symptoms on a four-point Likert scale over the past two weeks, ranging from “not at all” to “nearly every day”. Objective The aim of this study was to develop and validate a short form of the Eating Disorder Examination Questionnaire (EDE-Q) for routine, including session by session, outcome assessment. Chi square analyses were used to examine demographic differences, such as gender, age, ethnicity and level of education, between the two groups. The psychometric properties of the EDE-Q were explored using the Rasch model [28, 29]. The analyses were carried out separately for those respondents who reported a current eating disorder and those who did not. Two “yes” responses or more indicate that it is likely that the person is suffering from an eating disorder. not at all vs at least once per week. Changing the reference time period of the scale to seven days was intended to improve accuracy of recall and permit evaluation of change over a shorter time frame. Each item’s difficulty estimate was calculated to select those items from each subscale that capture both mild and more severe eating disorder symptoms. Many thanks go to Professor Chris Fairburn, the developer of the EDE-Q, who kindly supported this study. Forma breve di un modello Ogni modello ha anche una versione in " forma breve ". The GAD-7 is a brief seven item screening instrument for generalised anxiety disorder. Cronbach’s alpha coefficient showed that internal consistency for the EDE-QS was high (α = 0.913; N = 559). Further research will be needed to continue its psychometric evaluation in larger samples and diagnostically different groups. Bedfordshire and Luton Eating Disorders Service, East London NHS Foundation Trust, Dunstable, United Kingdom, Affiliations Inconsistencies between the EDE and the EDE-Q have also been observed in the self-report assessment of certain eating disorder features, such as objective binge eating behaviours [9, 17, 18, 22–25], laxative use [9] and self-induced vomiting [26]. The name SCOFF is an acronym of words referring to these characteristics (i.e. The COVID-19 Pandemic and Rapid Implementation of Adolescent and Young Adult Telemedicine: Challenges and Opportunities for Innovation. The current, 28-item version (6.0) of the EDE-Q was completed by 489 individuals aged 18–72 with various eating disorders recruited from three UK specialist eating disorder services. These range from a score of zero (“no symptoms”) to three (“extreme symptoms”). Cronbach’s alpha was 0.76 in the current study. (2017). The PHQ-9 has been found to have good psychometric properties [48]. The sample size of consulted experts in this study was small, and a convenience sampling method was used, which may have limited generalisability. The sample was divided into those who self-reported that they were currently suffering from an eating disorder and those who said they were not. The purpose of this study was to develop a short version of the EDE-Q, which could be used for sessional outcome monitoring. Most participants (88.9%) had completed higher education or basic university. However, validation of its use for this purpose would require data from both the short form and from a diagnostic measure such as the EDE interview [9, 18]. No, Is the Subject Area "Anorexia nervosa" applicable to this article? As the subscales have varying numbers of items, subscale scores are calculated as average scores per item, also ranging from ‘‘0” to ‘‘6”. Also, the use of diagnostic assessment or interviews would have been preferable to the online method. Nicole Gideon. A link to an online survey was emailed to mental health clinicians in the eating disorder field known to the authors. Saunders R, A 12-item short form, the Eating Disorder Examination Questionnaire Short (EDE-QS) was derived. In the first study a combination of PCA, Rasch modelling and expert ratings, was applied to identify the most relevant items for inclusion in a shortened version. The GAD-7 had good validity compared to independent mental health diagnoses, functional status measures, disability days and health care use [46] as well as good validity and reliability in the general population [47]. Eating disorder symptom severity is not a stable trait and is expected to vary to an extent from time to time. View Bookmark. This resulted in the 12 item EDE-QS (see S2 Appendix), which, unlike the original EDE-Q, consists of a single scale. See also. An email appeal providing a link to an online survey was sent out to all students of a London university. Please refer to Table 1 for experts’ individual item ratings. The goal of the first study was to develop a psychometrically and conceptually sound short form of the EDE-Q that could be used to measure session-by-session changes.
