Eating Attitudes Test (EAT-26)

The EAT-40 (original 1979 version, 40 items) is longer and more comprehensive but less commonly used today. The EAT-26 (1982 abbreviated version, 26 items) retains items most discriminative of eating disorders while reducing burden. EAT-26 is briefer, validated extensively, and preferred for screening and routine monitoring. Use EAT-26 unless you have a specific reason to use the full EAT-40 (e.g., research requiring original measure for historical comparison).

No. EAT-26 ≥20 indicates probable eating disorder with ~85% sensitivity but only ~80% specificity, meaning some false positives occur. Individuals with body image concerns, dieting for medical reasons, or preoccupation with food without clinical eating disorder may score ≥20. Diagnosis requires: (1) clinical interview, (2) detailed eating history (restriction pattern, binge-purge frequency, body dissatisfaction), (3) physical examination (weight, vital signs, medical complications), (4) DSM-5 criteria assessment (is the eating pattern causing significant distress or impairment?). EAT-26 ≥20 is referral threshold for evaluation, not diagnosis.

EAT-26 is less sensitive to males with eating disorders because items focus on weight/thinness concerns; males often pursue muscularity (muscle dysmorphia) rather than thinness. A male with EAT-26 = 15 but high preoccupation with muscle size, protein intake, and body image may still have an eating disorder. Ask supplementary questions about exercise obsession, muscle satisfaction, and protein/supplement use. Consider using more gender-neutral measures (SCOFF) or asking about eating disorder behaviors (restriction, excessive exercise) beyond EAT-26 scores in males.

Reduction of ≥50% from baseline EAT-26 score (or change from ≥20 to <20) indicates meaningful treatment response. For example, baseline EAT-26 = 50 → follow-up 20–25 shows substantial improvement. In intensive eating disorder treatment (inpatient or intensive outpatient), expect ≥30% improvement within 4 weeks; slower improvement suggests inadequate treatment intensity. Monitor every 1–2 weeks during intensive phase; every 4 weeks during step-down to outpatient.

Partially. EAT-26 subscales help: Dieting subscale elevation suggests restrictive pattern (anorexia); Bulimia subscale elevation suggests binge-eating or bulimia-type concerns. However, overlap is common (many patients restrict and binge), and EAT-26 does not directly ask about purging methods. For precise diagnosis, conduct clinical interview and dietary history. EAT-26 provides phenotypic hints but not definitive diagnosis of specific eating disorder subtype.

Minimal evidence supports that screening questions 'cause' eating disorders in previously unaffected individuals. However, discuss EAT-26 results compassionately; if score <20 and no concerns, reassure. If score 20–24 in someone without clinical presentation, explain it warrants follow-up but does not confirm disorder. Sensitive administration and follow-up conversation are important. For at-risk individuals (athletes, dancers), explain screening rationale: early identification enables early intervention.
