The Eating Disorder Examination Questionnaire (EDE-Q) Score Calculator computes subscale and global scores from the 28-item self-report measure of eating disorder psychopathology. Developed by Christopher Fairburn and Sarah Beglin as a self-report adaptation of the gold-standard Eating Disorder Examination interview (EDE), the EDE-Q assesses the frequency and severity of key behavioral and attitudinal features of eating disorders over the preceding 28 days. The EDE-Q yields four subscale scores: Restraint (5 items measuring dietary restriction and rules about eating), Eating Concern (5 items measuring preoccupation with food, eating in secret, guilt about eating), Shape Concern (8 items measuring dissatisfaction with body shape, discomfort seeing the body, importance placed on shape), and Weight Concern (5 items measuring dissatisfaction with weight, desire to lose weight, reaction to prescribed weighing). Each item is scored on a 0-to-6 frequency or severity scale, with each subscale score being the mean of its constituent items. The Global EDE-Q score is the mean of the four subscale scores. Community norms for the Global EDE-Q score vary by gender and age. Among young adult women, community norms typically range from 1.5 to 2.5, while men score lower at 0.8 to 1.5. A Global score above 4.0 is generally considered indicative of clinical significance, though diagnosis requires comprehensive clinical evaluation. The EDE-Q also includes diagnostic items assessing the frequency of specific behaviors (binge eating episodes, self-induced vomiting, laxative use, excessive exercise) over the past 28 days, which are scored separately and inform diagnostic formulation. The EDE-Q is the most widely used self-report measure of eating pathology in both clinical practice and research. It is used for screening in primary care and college health settings, monitoring treatment progress in specialized eating disorder programs, measuring outcomes in clinical trials of eating disorder treatments, and conducting epidemiological research on the prevalence and correlates of disordered eating. The calculator ensures accurate scoring and provides context for interpreting results against published norms.
Restraint Subscale = mean of items 1, 2, 3, 4, 5 (each 0-6) Eating Concern Subscale = mean of items 7, 9, 19, 20, 21 (each 0-6) Shape Concern Subscale = mean of items 6, 8, 10, 11, 23, 26, 27, 28 (each 0-6) Weight Concern Subscale = mean of items 8, 12, 22, 24, 25 (each 0-6) Global EDE-Q Score = (Restraint + Eating Concern + Shape Concern + Weight Concern) / 4 Worked Example: Restraint: (4+3+2+5+3)/5 = 3.40 Eating Concern: (2+1+3+4+2)/5 = 2.40 Shape Concern: (5+4+3+4+5+6+5+4)/8 = 4.50 Weight Concern: (4+5+3+4+5)/5 = 4.20 Global = (3.40+2.40+4.50+4.20)/4 = 3.63 (elevated but below clinical cutoff of 4.0)
- 1Complete all 28 items of the EDE-Q based on your experiences over the past 28 days (4 weeks). Items 1 through 12 and item 19 ask about the number of days a particular behavior or experience occurred, using a 0-to-6 scale where 0 means no days and 6 means every day. Items 13 through 18 ask about the frequency of specific behaviors (binge eating, vomiting, laxative use, and excessive exercise) as a count of episodes, not days. Items 20 through 28 use a 0-to-6 severity scale where 0 means not at all and 6 means markedly. It is essential to complete all items honestly for accurate scoring.
- 2The calculator assigns each item to its designated subscale according to the published scoring key. Note that item 8 is included in both the Shape Concern and Weight Concern subscales, which is intentional in the original EDE-Q design. Items 13 through 18 are behavioral frequency items that are not included in the subscale calculations; they are reported separately as diagnostic indicators. The calculator flags any missing items and can compute subscale scores with up to one missing item per subscale using the mean of available items.
- 3Each subscale score is calculated as the arithmetic mean of its constituent items, yielding a value between 0.00 and 6.00. Higher scores indicate greater severity of eating pathology in that domain. The Restraint subscale captures the degree of dietary restriction and rule-driven eating. The Eating Concern subscale measures preoccupation with food and eating, including secret eating and guilt. The Shape Concern subscale assesses body image disturbance related to shape. The Weight Concern subscale evaluates dissatisfaction with weight and the importance placed on weight.
- 4The Global EDE-Q score is calculated as the unweighted mean of the four subscale scores. This provides a single summary measure of overall eating disorder psychopathology severity. The Global score ranges from 0.00 to 6.00. Research has established that a Global score at or above 4.0 has high sensitivity and specificity for identifying individuals with clinically diagnosable eating disorders, though the optimal cutoff varies by population and purpose (screening versus diagnosis).
- 5The behavioral frequency items (items 13 through 18) are reported as the number of episodes in the past 28 days. These include: objective binge eating episodes (OBE), subjective binge eating episodes (SBE), self-induced vomiting, laxative use, and excessive exercise driven by weight or shape concerns. A frequency of four or more OBE episodes per 28 days meets one diagnostic criterion for bulimia nervosa and binge eating disorder. These behavioral frequencies are critical for diagnostic formulation and treatment planning.
- 6Compare the results against published normative data for the appropriate reference population. Community norms for young adult women (the most extensively studied group) show mean Global scores of approximately 1.5 to 2.5, with a standard deviation of approximately 1.3. Clinical eating disorder samples typically show mean Global scores of 3.5 to 4.5. Male norms are lower, with community means of approximately 0.8 to 1.5. The calculator displays the user scores alongside normative percentile ranks to contextualize the results.
- 7Review the clinical interpretation and recommendations. The calculator provides a severity classification (minimal, mild, moderate, severe) for each subscale and the Global score, along with a recommendation for whether further clinical evaluation is warranted. Scores in the clinical range on any subscale should prompt referral to a healthcare provider with expertise in eating disorders, regardless of the Global score. The EDE-Q is a screening and monitoring tool, not a diagnostic instrument; definitive diagnosis requires a comprehensive clinical evaluation including the interview-based EDE, medical assessment, and psychological evaluation.
This individual shows subclinical but notable shape and weight concerns (elevated above community means) with minimal eating concern and low restraint. The Global score of 1.94 is within the normal community range for young adult women (approximately 50th percentile) but the Shape Concern subscale of 2.75 warrants monitoring, particularly if the individual expresses distress about body image. No clinical referral is indicated at this level, but psychoeducation about body image and self-compassion may be beneficial.
All four subscale scores are in the clinical range, with a Global score of 5.03 substantially exceeding the clinical cutoff of 4.0. This pattern is consistent with a clinically significant eating disorder, most likely anorexia nervosa restrictive type given the extremely high Restraint score, or bulimia nervosa if accompanied by binge-purge behaviors. Immediate referral to a specialized eating disorder treatment provider is strongly recommended, along with medical evaluation for nutritional status, electrolyte imbalances, and cardiac health.
After completing a course of cognitive-behavioral therapy for eating disorders (CBT-E), this individual shows Global scores well within the community normal range at 1.14. The Shape Concern subscale remains the highest at 1.75, which is common in recovery as body image concerns often persist longer than behavioral symptoms. The improvement from a pre-treatment Global of 4.2 to 1.14 represents clinically meaningful recovery. Continued monitoring at three-month intervals is recommended to detect any relapse trajectory.
Eating disorder treatment programs use the EDE-Q at intake, during treatment, and at discharge to measure symptom change and treatment effectiveness. A reduction in Global score of 1.0 or more is considered clinically meaningful. The EDE-Q is the primary outcome measure in the majority of eating disorder treatment trials published in the International Journal of Eating Disorders and European Eating Disorders Review.
College health centers and university counseling services use the EDE-Q as a screening tool during routine health assessments. Eating disorders affect an estimated 10 to 20 percent of college women and 4 to 10 percent of college men, with peak onset during the ages of 18 to 25. Early detection through standardized screening significantly improves treatment outcomes and reduces the duration of illness.
Primary care physicians use abbreviated versions of the EDE-Q (the EDE-QS, a 12-item short form) for rapid screening during annual physicals or when patients present with weight-related concerns, GI symptoms, or menstrual irregularities that may indicate an underlying eating disorder. The short form takes under 5 minutes to complete and has comparable sensitivity to the full 28-item version.
Researchers conducting epidemiological studies of eating pathology use the EDE-Q because it is freely available (no license fee), has been translated into over 30 languages, and has extensive published normative data across diverse populations. This makes it the de facto standard for cross-cultural and cross-national comparisons of eating disorder prevalence and severity.
Individuals with atypical anorexia nervosa (meeting all criteria for anorexia
Individuals with atypical anorexia nervosa (meeting all criteria for anorexia nervosa except being underweight) may show high EDE-Q scores despite having a normal or above-normal BMI. This presentation is increasingly recognized as clinically significant, with medical complications (bradycardia, orthostatic hypotension, electrolyte disturbances) comparable to those seen in typical anorexia nervosa. The EDE-Q correctly identifies elevated eating pathology in these individuals, but clinicians must not dismiss high scores based solely on weight status.
Post-bariatric surgery patients often score in unusual patterns on the EDE-Q,
Post-bariatric surgery patients often score in unusual patterns on the EDE-Q, with elevated Restraint scores that reflect medically prescribed dietary restrictions rather than eating disorder psychopathology. The calculator can be configured to note that post-surgical Restraint scores should be interpreted cautiously and that Eating Concern and binge eating frequency items may be more clinically relevant in this population.
Individuals from non-Western cultural backgrounds may endorse different
Individuals from non-Western cultural backgrounds may endorse different patterns of eating pathology that the EDE-Q does not fully capture. Shape and weight concerns manifest differently across cultures: in some East Asian populations, concerns about specific body parts (such as facial shape) may be more prominent than overall body dissatisfaction. The EDE-Q has been validated in multiple cultural contexts but cultural competence in interpretation is essential. Use culturally appropriate norms when available rather than defaulting to Western norms.

What does a Global score above 4.0 mean?
A Global EDE-Q score at or above 4.0 indicates that the individual eating-related attitudes and behaviors are in a range that is clinically significant and consistent with an eating disorder diagnosis. However, this is a screening threshold, not a diagnostic criterion. Definitive diagnosis requires a comprehensive clinical evaluation including a structured clinical interview (ideally the EDE interview version), medical assessment, and consideration of differential diagnoses. Not all individuals scoring above 4.0 have a diagnosable eating disorder, and some individuals with eating disorders score below 4.0.
How is the EDE-Q different from the EDE interview?
The EDE is a semi-structured clinical interview lasting 45 to 75 minutes, administered by a trained clinician. It is the gold standard for eating disorder assessment and provides more nuanced and reliable data than any self-report measure. The EDE-Q is a self-report questionnaire adaptation that takes 10 to 15 minutes to complete. The two measures are moderately to highly correlated (r = 0.60 to 0.85 depending on the subscale) but differ in key ways: the EDE-Q tends to produce higher Shape Concern and Weight Concern scores than the EDE interview, and the EDE provides more reliable assessment of binge eating episodes because it clarifies the distinction between objective and subjective binges.
Can the EDE-Q be used with males?
Yes, but with important caveats. The EDE-Q was originally developed and normed primarily on female samples. Male community norms are lower than female norms (approximately 0.8 to 1.5 versus 1.5 to 2.5 for the Global score). Some researchers have questioned whether the EDE-Q adequately captures male-specific eating concerns such as muscularity-oriented eating, supplement use, and exercise-driven body composition goals. Modified versions like the Male Body Attitudes Scale may be more appropriate for assessing male-specific body image concerns.
How often should the EDE-Q be administered during treatment?
In clinical practice, the EDE-Q is typically administered at intake, at regular intervals during treatment (monthly or at session 4, 8, 12, etc.), at treatment completion, and at follow-up (3, 6, and 12 months post-treatment). The 28-day recall window means administrations should be spaced at least 4 weeks apart to avoid overlapping assessment periods. More frequent administration reduces the reliability of change scores because the measure is designed to capture patterns over the full 28-day period.
Is the EDE-Q sensitive to treatment change?
Yes. The EDE-Q has demonstrated good sensitivity to change in numerous treatment trials. A Global score reduction of 1.0 or more is considered clinically meaningful, and a reduction to within one standard deviation of community norms (approximately below 2.77 for young women) is considered an indicator of recovery. The Restraint and Eating Concern subscales tend to show the fastest response to treatment, while Shape Concern and Weight Concern typically improve more slowly and may remain elevated even after behavioral recovery.
プロのヒント
When interpreting EDE-Q results, always examine the subscale profile rather than relying solely on the Global score. Two individuals with the same Global score of 3.0 may have very different clinical presentations: one with uniformly moderate scores and another with extreme Shape Concern (5.5) but near-zero Restraint and Eating Concern. The subscale profile guides treatment focus. High Restraint suggests the need for nutritional rehabilitation and flexible eating skills. High Shape/Weight Concern suggests the need for body image work and cognitive restructuring. High Eating Concern suggests the need for addressing binge eating triggers and food-related anxiety.
ご存知でしたか？
The original Eating Disorder Examination interview was developed by Christopher Fairburn at Oxford University in the 1980s and has become the most cited eating disorder assessment in the scientific literature, with over 15,000 citations. The self-report adaptation (EDE-Q) was created because the interview requires 45 to 75 minutes of clinician time per administration, making it impractical for large-scale research and routine clinical monitoring. The EDE-Q takes only 10 to 15 minutes and can be scored by computer, dramatically expanding its accessibility.
