Family-Based Treatment (Maudsley Approach) for Adolescent Eating Disorders
Overview
Family-Based Treatment (FBT), also known as the Maudsley approach, is the first-line evidence-based treatment for adolescent anorexia nervosa. Developed at the Maudsley Hospital in London and manualized by Lock and Le Grange, FBT is built on a core principle: the illness has taken control of the adolescent's eating, and parents must be empowered as the primary agents of refeeding until the adolescent can resume age-appropriate autonomy. FBT externalizes the illness, separating the eating disorder from the adolescent's identity. It holds the strongest evidence base of any psychotherapy for adolescent AN and has also been adapted for adolescent bulimia nervosa. Treatment is typically conducted over 6-12 months in approximately 15-20 sessions.
Theoretical Foundations
Agnostic Stance on Etiology
FBT explicitly does not blame parents for causing the eating disorder. It takes an agnostic stance on etiology, asserting that the cause is less important than the solution. This is a deliberate rejection of the historical — and harmful — idea that family dysfunction causes eating disorders. Instead, parents are viewed as the most important resource for recovery, not as the cause of illness.
Externalization of the Illness
The eating disorder is conceptualized as an external force that has taken over the adolescent's ability to eat normally. The adolescent is not choosing to restrict; the illness is compelling the restriction. This framing reduces blame and guilt while simultaneously empowering parents to take action. The clinician's role is to help the family "separate the child from the illness."
Parental Empowerment
Unlike individual therapy approaches that rely on the adolescent to manage their own eating, FBT recognizes that a malnourished adolescent cannot make rational decisions about food. Parents know their child and are available around the clock, making them the most powerful agents of change. The therapist serves as a consultant to the parents rather than as the primary agent of change. This mirrors the approach taken for other serious pediatric illnesses — just as parents manage a diabetic child's insulin, they manage their child's nutrition during AN recovery.
The Three Phases of FBT
Phase 1: Weight Restoration (Sessions 1-10)
The goal of Phase 1 is for parents to take full control of the adolescent's eating to achieve weight restoration. Session 1 is a family session that includes all family members, during which the therapist takes a detailed history, expresses serious concern about the medical danger of the illness, and charges the parents with the task of refeeding their child. Session 2, the family meal, is a signature FBT intervention: the family brings a meal to the session, and the therapist observes family dynamics around eating, coaches parents in encouraging the adolescent to eat "one more bite" than the eating disorder allows, and provides in-vivo feedback. In subsequent Phase 1 sessions, the patient is weighed at each visit, and the therapist helps parents problem-solve around meals, addresses sibling concerns, supports parents in maintaining a unified front, and manages the adolescent's resistance. During this phase, parents decide what, when, and how much the adolescent eats. The adolescent is temporarily relieved of responsibility for food decisions. Siblings are supported and their needs acknowledged. Weight gain of approximately 0.5-1 kg per week is expected. Phase 1 continues until weight is approaching the target range and eating patterns are improving.
Phase 2: Returning Control to the Adolescent (Sessions 11-16)
Phase 2 involves the gradual transfer of eating control back to the adolescent as weight and eating stabilize. It begins when weight is approaching target, parents feel confident in managing meals, and the adolescent is beginning to eat more independently. The process is gradual: the adolescent receives increasing autonomy over food choices, starting with lower-stakes meals such as snacks or eating with peers. Parents remain vigilant and step back in if weight drops or eating deteriorates. Normal adolescent developmental tasks — socializing, school engagement, age-appropriate independence — resume during this phase. Family conflict related to food typically decreases.
Summary of FBT Phases
| Phase | Sessions | Goal | Who Controls Eating | Key Activities |
|---|---|---|---|---|
| Phase 1: Weight Restoration | 1-10 | Restore weight to target range | Parents (full control) | Family meal (Session 2), parental refeeding, weight monitoring |
| Phase 2: Returning Control | 11-16 | Gradual transfer of eating autonomy | Shared (gradual handoff) | Increasing adolescent choice, starting with lower-stakes meals |
| Phase 3: Healthy Identity | 17-20 | Establish identity independent of ED | Adolescent (self-managed) | Address developmental tasks, relapse prevention |
Phase 3: Establishing Healthy Adolescent Identity (Sessions 17-20)
Phase 3 addresses broader adolescent development issues and helps establish a healthy identity independent of the eating disorder. The impact of the illness on adolescent development is reviewed across social, academic, and identity domains. Normal adolescent concerns are discussed: autonomy, peer relationships, emerging independence, and future planning. A relapse prevention plan is established. Treatment ends when weight is stable at target, eating is self-managed, and adolescent developmental tasks have resumed. Notably, there is no specific focus on body image or "underlying causes," as these often improve with weight restoration and developmental re-engagement.
Evidence Base
Key Trials
| Study | Comparison | FBT Full Remission | Comparator Remission | Key Finding |
|---|---|---|---|---|
| Russell et al. (1987) | FBT vs. individual therapy | Superior | Inferior | FBT superior for AN <3 years duration, onset <19 |
| Lock et al. (2010) | FBT vs. AFT | 42% (EOT), 49% (12-mo) | 23% (EOT), 23% (12-mo) | FBT significantly superior at both timepoints |
| Le Grange et al. (2016) | FBT vs. AFT (n=164) | Superior | Inferior | Largest RCT; FBT superiority maintained at follow-up |
| Agras et al. (2014) | FBT vs. SyFT | Effective | Effective | No significant difference between family-based approaches |
Russell et al. (1987) conducted the original Maudsley study showing that family therapy was superior to individual therapy for adolescents with AN of less than 3 years duration and onset before age 19. Lock et al. (2010) conducted an RCT comparing FBT to adolescent-focused therapy (AFT), finding higher full remission rates with FBT both at end of treatment (42% versus 23%) and at 12-month follow-up (49% versus 23%). Le Grange et al. (2016) published the largest RCT to date, comparing FBT to AFT in 164 adolescents, with FBT demonstrating superiority at end of treatment and maintaining that superiority at follow-up. Agras et al. (2014) compared FBT to systemic family therapy (SyFT) and found no significant difference between the two family-based approaches, with both proving effective. Overall, FBT achieves full remission in approximately 40-50% of adolescents by end of treatment, with additional improvement at follow-up.
Who Responds Best
Better outcomes are predicted by earlier presentation in the illness course (shorter duration predicts better response), younger age, less severe eating disorder psychopathology at baseline, non-purging subtype, and intact two-parent families (though FBT can be adapted for single-parent and non-traditional families). Comorbid depression and anxiety are common and do not preclude FBT.
Who May Need Augmentation or Alternative
Adolescents who may need augmentation or an alternative approach include those with severe comorbid psychopathology (OCD, PTSD, personality disorder features), older adolescents (ages 17-18 and above) who resist parental control, families with high conflict, domestic violence, or parental psychopathology that impedes collaboration, and adolescents who do not respond to FBT after an adequate trial of 12-16 sessions without weight gain. For non-responders, options include a higher level of care (intensive outpatient, residential, or inpatient), individual therapy approaches such as CBT-E or AFT, or modified FBT protocols.
FBT Adaptations
FBT for Bulimia Nervosa (FBT-BN)
FBT has been adapted by Le Grange for adolescent bulimia nervosa. An RCT (Le Grange et al., 2007) demonstrated that FBT-BN was superior to supportive psychotherapy for adolescent BN at both end of treatment and 6-month follow-up. The principles are similar: parental oversight of meals to prevent binge-purge episodes, externalization of the illness, and gradual return of control. Parents monitor meals and the post-meal period and work to establish regular eating patterns.
Multi-Family Therapy (MFT)
Multi-family therapy brings groups of 5-8 families together for intensive treatment, often in a multi-day format. It combines FBT principles with group process, allowing families to learn from each other and reducing the isolation that often accompanies eating disorder treatment. MFT has a growing evidence base and has been particularly effective in some healthcare systems, including those in the UK and Europe.
Adaptations for Diverse Families
For single-parent families, other supportive adults — grandparents, aunts, uncles, or close friends — should be identified to share the refeeding burden. For divorced families, both parents must collaborate on refeeding even if they disagree on other matters, and the therapist may need to mediate this collaboration. Cultural adaptations include using culturally appropriate meals, respecting cultural food practices, and providing language-appropriate materials.
Common Challenges in FBT
Adolescent Resistance
Resistance from the adolescent is expected and normal — it reflects the eating disorder resisting parental intervention. The therapist helps parents tolerate the adolescent's distress and anger without backing down. A key message for parents is: "You are not fighting your child; you are fighting the illness." Extreme resistance may manifest as aggression, property destruction, or threats of self-harm.
Parental Guilt and Self-Blame
Despite FBT's agnostic stance on etiology, parents frequently blame themselves. The therapist actively works to reduce this guilt: "You did not cause this, and you are the most important part of the solution." Supporting parental self-care and stress management is essential.
Siblings
Siblings are affected by the family's intense focus on the ill adolescent. They should be included in sessions and their experiences acknowledged. Siblings can also be powerful allies in the recovery process.
Meal-Related Conflict
Mealtimes often become battlegrounds. The therapist coaches parents in firm but calm approaches. Parents should avoid negotiating with the eating disorder and should make food decisions themselves. Distraction techniques, a structured meal environment, and planned post-meal activities can help manage this difficult phase.

Clinical Pearls
FBT is the first-line treatment for adolescent AN with the strongest evidence base and should be offered before individual therapy approaches. FBT does not blame parents — it empowers them as the primary agents of recovery. The family meal (Session 2) is a signature FBT intervention in which the therapist observes and coaches parents in real-time as they encourage the adolescent to eat. Phase 1 is the most critical phase: parents must take full control of eating until weight restoration occurs, and this control is temporary, not permanent. Externalizing the illness ("the anorexia is telling you not to eat") reduces blame, maintains the therapeutic alliance, and preserves the parent-adolescent relationship. FBT works best for younger adolescents earlier in the illness course; longer illness duration and older age predict poorer response. When FBT fails (no weight gain after 12-16 sessions), escalation to a higher level of care is warranted. Siblings are important family members whose needs should be acknowledged and who can serve as allies in recovery.
