Body Shape Questionnaire (BSQ)
Body Shape Questionnaire · Also known as: BSQ-34, Body Shape Questionnaire Revised (BSQ-R), Cooper Body Shape Questionnaire
The BSQ is a self-report questionnaire measuring preoccupation with and dissatisfaction about body shape. Originally developed by Cooper and colleagues in 1987, the full version contains 34 items; shorter versions (BSQ-16, BSQ-8) are also widely used. The BSQ was designed to assess body shape concern as a core psychopathological feature of eating disorders and is widely used in eating disorder assessment, body image research, and epidemiological studies.

When to use it
The BSQ is recommended in clinical settings for screening patients with suspected eating disorders or body image concerns, for monitoring body image during eating disorder treatment, and for research into body dissatisfaction and eating pathology. It is appropriate for adolescents (14+) and adults. The BSQ is particularly useful in studies of cultural variation in body ideals, social media influence on body image, and longitudinal tracking of body dissatisfaction. It is less appropriate as a diagnostic tool for eating disorders (requires comprehensive assessment) or body dysmorphic disorder (which has specific diagnostic criteria not fully captured by BSQ).
Strengths & limitations
- Focused measurement of a core eating disorder construct — body shape concern is a key cognitive feature in eating disorder psychopathology; the BSQ measures this directly without confounding with behavioral or appetite dimensions.
- Strong psychometric properties — good internal consistency (Cronbach's α ≥ 0.85 for BSQ-34), test-retest reliability (r ≥ 0.88 over 1–2 weeks), and convergent validity with other body dissatisfaction measures.
- Multiple versions — full 34-item version for comprehensive assessment and shorter 16-item or 8-item versions for efficiency, allowing flexibility in research and clinical settings.
- Validated in diverse populations — adolescents, adults, clinical eating disorder samples, general population, and 30+ language translations across diverse cultures.
- Sensitive to treatment change — BSQ scores decrease meaningfully during eating disorder treatment, making it suitable for monitoring progress during therapy or intervention.
- Does not diagnose eating disorders — high BSQ scores reflect body shape concern but do not indicate eating disorder diagnosis. Many individuals with high BSQ scores do not meet criteria for eating disorder.
- Cannot distinguish body dysmorphic disorder from eating disorder-related body concern — both produce high BSQ scores; clinical interview is necessary to differentiate.
- Limited measurement of actual eating behaviours or restraint — the BSQ is cognitive/affective, not behavioural. Combine with EDE-Q for complete eating pathology assessment.
- Sensitive to diet culture and social pressure regarding appearance — BSQ scores reflect both individual vulnerability and sociocultural context (media, fashion norms). Interpretation requires cultural awareness.
- Does not measure positive body image or body functionality — the BSQ is unidimensional (dissatisfaction only). It does not capture self-efficacy, strength, or appreciation of one's body.
Frequently asked
What BSQ cutoff indicates eating disorder risk?
A BSQ-34 score ≥81 suggests elevated body shape concern warranting clinical assessment. Scores >110 indicate severe concern. However, cutoffs vary by population: clinical samples have higher mean scores; general population norms differ. Always consult reference data for your specific population. A positive BSQ should prompt EDE-Q and clinical interview, not diagnosis on its own.
My adolescent daughter scored high on the BSQ. Does this mean she has an eating disorder?
Not necessarily. High BSQ indicates body shape dissatisfaction, which is common in adolescents but is not synonymous with eating disorder. Ask about eating behaviors, weight changes, exercise patterns, and emotional distress. A comprehensive assessment including EDE-Q, dietary history, and physical examination is needed. Many adolescents with body concerns do not develop eating disorders.
Should I use the BSQ-34, BSQ-16, or BSQ-8?
Use BSQ-34 for comprehensive assessment and detailed measurement. Use BSQ-16 or BSQ-8 for efficiency in busy clinics or large epidemiological studies. Shorter versions are slightly less detailed but maintain good reliability. Check published norms for the version you choose to ensure appropriate interpretation.
Can I use the BSQ to measure treatment response in eating disorders?
Yes. BSQ scores typically decrease during eating disorder treatment (cognitive-behavioural therapy, family-based treatment) as preoccupation and distress diminish. However, BSQ alone is insufficient to monitor treatment; use it alongside EDE-Q (for overall eating pathology), weight/nutrition markers, and behavioral recovery.
