Eating Disorder Examination Questionnaire (EDE-Q)

The Eating Disorder Examination Questionnaire (EDE-Q) is a widely used, self-report questionnaire designed to assess eating disorder psychopathology and behaviours. Developed by Dr. Christopher Fairburn and colleagues as a self-report version of the Eating Disorder Examination (EDE) interview, the EDE-Q measures the core cognitive and behavioural features of eating disorders over the past 28 days. It is considered one of the most comprehensive and psychometrically sound measures for assessing eating disorder symptoms, making it invaluable for screening, diagnosis, treatment planning, and research in eating disorders.

Understanding Eating Disorder Assessment

Why Specialised Assessment is Needed:

• Complex symptoms - eating disorders involve multiple psychological and behavioural components
• Hidden behaviours - many eating disorder behaviours are secretive
• Cognitive distortions - distorted thinking about food, weight, and body shape
• Medical complications - physical health consequences require assessment
• Comorbidity - high rates of co-occurring mental health conditions

Core Features of Eating Disorders:

• Dietary restraint - restriction of food intake
• Weight and shape concerns - overvaluation of weight and body shape
• Eating concerns - preoccupation with food and eating
• Binge eating - episodes of overeating with loss of control
• Compensatory behaviours - vomiting, laxative use, excessive exercise

Structure and Content of the EDE-Q

Scale Format:

• 28 items - covering eating disorder symptoms
• Self-report - completed by the individual
• 28-day timeframe - assesses symptoms over past 4 weeks
• 7-point scale - 0 (no days/not at all) to 6 (every day/markedly)
• 15-20 minutes - typical completion time

Four Subscales: 1. Dietary Restraint (5 items):

• Attempts to restrict food intake
• Avoidance of eating
• Food avoidance when hungry
• Dietary rules and restrictions
• Empty stomach as goal

2. Eating Concern (5 items):

• Preoccupation with food and eating
• Fear of losing control over eating
• Social eating anxiety
• Guilt about eating
• Secret eating

3. Weight Concern (5 items):

• Importance of weight
• Reaction to weight gain
• Dissatisfaction with weight
• Desire to lose weight
• Preoccupation with weight

4. Shape Concern (8 items):

• Importance of body shape
• Fear of weight gain
• Feelings of fatness
• Dissatisfaction with shape
• Discomfort seeing body
• Avoidance of exposure
• Flat stomach importance
• Reaction to shape changes

Behavioural Items (5 items):

• Objective binge episodes
• Subjective binge episodes
• Self-induced vomiting
• Laxative misuse
• Driven or compensatory exercise

Scoring and Interpretation

Subscale Scoring:

• Average item scores - sum items and divide by number of items
• Range - 0 to 6 for each subscale
• Higher scores - indicate greater eating disorder psychopathology
• Global score - average of four subscale scores
• Behavioural frequencies - number of episodes in past 28 days

Severity Interpretation:

• 0-1 - Minimal eating disorder psychopathology
• 1-2 - Mild eating disorder features
• 2-3 - Moderate eating disorder symptoms
• 3-4 - Marked eating disorder psychopathology
• 4+ - Severe eating disorder symptoms

Note: The severity ranges presented (0–4+) are not formally standardised or diagnostically defined. They are provided as general clinical heuristics commonly used in research and practice to aid interpretation of scores. Severity should always be considered in context, alongside subscale patterns, behavioural frequency data, clinical interview findings, and individual demographic factors. These ranges are intended to support understanding, not to replace comprehensive assessment or diagnosis.

Clinical Cutoff Scores:

• ≥2.5 - Suggested cutoff for eating disorder diagnosis
• ≥4.0 - Severe eating disorder psychopathology
• Context-dependent - interpretation varies by population
• Subscale patterns - different patterns suggest different disorders
• Behavioural thresholds - specific frequencies for binge/purge behaviours

Diagnostic Considerations:

• Anorexia nervosa - high restraint, weight/shape concern, low weight
• Bulimia nervosa - binge eating, compensatory behaviours, weight/shape concern
• Binge eating disorder - binge eating without regular compensation
• OSFED - other specified feeding or eating disorder
• Clinical judgement - always combine with clinical assessment

Clinical Applications

Screening and Assessment:

• Eating disorder screening - identifying individuals at risk
• Diagnostic support - providing information for diagnosis
• Severity assessment - quantifying symptom severity

Progress Monitoring:

• Treatment response - tracking improvement during therapy
• Symptom changes - monitoring specific symptom domains
• Relapse prevention - detecting early warning signs
• Outcome evaluation - measuring treatment effectiveness
• Long-term follow-up - assessing sustained recovery

Research Applications

Psychometric Properties

Reliability:

• Internal consistency - Cronbach's alpha 0.85-0.93 for subscales
• Test-retest reliability - stable over short periods (r = 0.81-0.94)
• Excellent reliability - meets high psychometric standards

Remember

The EDE-Q is a valuable tool for assessing eating disorder psychopathology, but it should always be used as part of a comprehensive evaluation that includes medical assessment, clinical interview, and consideration of the individual's unique circumstances. While it provides important quantitative information about eating disorder symptoms, it cannot replace thorough clinical assessment and professional judgment. The EDE-Q is most effective when used by trained professionals who understand eating disorders, body image issues, and the complex factors that contribute to these conditions. High scores indicate the need for specialised eating disorder treatment, which can be highly effective with appropriate intervention and support.
