Overview
Anorexia Nervosa (AN) is a serious eating disorder characterized by persistent restriction of energy intake, intense fear of gaining weight, and a distorted perception of body image. Individuals with anorexia often experience a relentless pursuit of thinness and significant distress about weight or shape, even when underweight. This condition can lead to severe medical complications, including electrolyte imbalance, cardiac abnormalities, bone density loss, and multi-organ dysfunction. Treatment focuses on medical stabilization, weight restoration, nutritional rehabilitation, and addressing cognitive and emotional factors underlying restrictive eating and body image disturbance.
Indicated Evidence-Based Practices (EBPs)
- Family-Based Treatment (FBT, “Maudsley Method”) – first-line approach for adolescents; empowers parents to support nutritional rehabilitation and reduce restrictive behaviors
- Enhanced Cognitive Behavioral Therapy (CBT-E) – structured, transdiagnostic model addressing overvaluation of weight and shape, perfectionism, and avoidance behaviors
- Dialectical Behavior Therapy (DBT) for Eating Disorders – integrates mindfulness and emotion regulation to target rigidity, distress intolerance, and self-punitive behaviors
- Adolescent-Focused Therapy (AFT) – explores developmental and identity-related issues contributing to restriction and control
- Specialist Supportive Clinical Management (SSCM) – combines psychoeducation, supportive therapy, and nutritional guidance; evidence-based for adults
- Acceptance and Commitment Therapy (ACT) – promotes values-based recovery and willingness to experience distress related to food and body image
- Nutritional Rehabilitation and Medical Monitoring – critical adjunct to psychotherapy; multidisciplinary approach involving physicians, dietitians, and mental health providers
When to Choose What
FBT is the evidence-based first-line intervention for adolescents living with family support.
CBT-E is the preferred approach for adults and older adolescents, with broad efficacy across eating disorder presentations.
SSCM may be suitable for adults preferring a less intensive or more flexible therapeutic structure.
DBT-informed work is beneficial for individuals with high emotional dysregulation, impulsivity, or self-harm behaviors.
ACT can be integrated once nutritional stabilization is underway to address cognitive rigidity and avoidance.
Inpatient or residential care is indicated when BMI, medical risk, or suicidal behavior requires structured support and monitoring.
Core Components of Treatment
- Psychoeducation about anorexia’s physical and psychological consequences
- Nutritional rehabilitation and restoration of healthy eating patterns
- Family involvement in meal support and relapse prevention (especially in FBT)
- Cognitive restructuring of beliefs about weight, shape, and control
- Emotion identification, regulation, and distress tolerance skills
- Body image work through exposure, mindfulness, and body neutrality practices
- Values clarification to support identity beyond weight and appearance
- Development of autonomy, relational skills, and self-compassion
- Coordination among multidisciplinary team members for safety and consistency
Measures and Monitoring
Screening and diagnostic tools
- Eating Disorder Examination (EDE) and EDE-Questionnaire (EDE-Q): gold-standard assessments for eating disorder cognitions and behaviors
- Eating Disorder Inventory-3 (EDI-3): evaluates psychological traits contributing to disordered eating
- SCOFF Questionnaire: brief screening tool for disordered eating risk
- Body Shape Questionnaire (BSQ): measures body image disturbance
- Beck Depression Inventory-II (BDI-II) and GAD-7: assess co-occurring anxiety and depression
- Medical assessments: BMI, electrolyte panels, ECG, and bone density evaluations for physical health monitoring
Monitoring and outcome tools
- EDE-Q or EDI-3 administered every 6–8 sessions to track symptom changes
- Weight and vital sign monitoring coordinated by medical staff
- Food logs and behavioral tracking for exposure and self-monitoring
- WHO-5 Well-Being Index for global functioning and quality of life
- Session Rating Scale (SRS) for therapeutic engagement and alliance
Adaptations and Special Considerations
Medical stability: Treatment begins with medical evaluation and stabilization. Life-threatening complications must be addressed before or alongside psychotherapy.
Therapeutic stance: Maintain empathy and nonjudgment while firmly reinforcing recovery goals. Avoid power struggles about food or weight.
Family involvement: Essential in adolescent treatment; educate caregivers on supporting recovery without blame or coercion.
Comorbidity: Depression, anxiety, obsessive-compulsive traits, and trauma histories are common and require integrated care.
Cultural sensitivity: Recognize sociocultural factors influencing body ideals and eating behaviors; avoid weight-normative assumptions.
Trauma-informed care: Address perfectionism, control, and shame through safe, paced exploration.
Relapse prevention: Focus on building flexible coping strategies and internal motivation for ongoing recovery.
Telehealth: Can be effective for CBT-E or FBT with structured monitoring and meal support coordination; ensure privacy and accountability measures.
