Cognitive-Behavioral Therapy (CBT) and Enhanced CBT for Eating Disorders
Cognitive-behavioral therapy (CBT) is widely recognized as the most effective psychological treatment for bulimia nervosa and binge eating disorder, with strong evidence supporting its use in both full and guided self-help forms Russell2023Kass2013Hay2013+4 MORE. Enhanced CBT (CBT-E), which is a more flexible and transdiagnostic version, has shown improved outcomes for both adults and youth with various eating disorders Kass2013Waller2016. CBT focuses on changing unhealthy eating behaviors and thoughts, and is often considered the first-line therapy for bulimia nervosa and binge eating disorder Russell2023Kass2013Hay2013+4 MORE.
Family-Based Therapy (FBT) for Anorexia Nervosa in Youth
Family-based therapy, particularly the Maudsley method, is the most established and effective treatment for adolescents with anorexia nervosa, and may also be beneficial for youth with bulimia nervosa Russell2023Kass2013Bhadoria2010+4 MORE. This approach involves the family in supporting the young person’s recovery and has the strongest evidence base for this age group and diagnosis Russell2023Kass2013Bhadoria2010+4 MORE.
Interpersonal Psychotherapy (IPT) and Other Therapies
Interpersonal psychotherapy (IPT) is another well-supported treatment, especially for bulimia nervosa and binge eating disorder, and has also shown promise in preventing excess weight gain in at-risk youth Russell2023Kass2013Hay2013+1 MORE. Dialectical behavior therapy (DBT) has shown some promise for binge eating disorder, but more research is needed to confirm its long-term effectiveness Russell2023Iacovino2012. Other therapies with emerging evidence include Acceptance and Commitment Therapy (ACT), Integrative Cognitive Affective Therapy, Exposure Therapy, Mindfulness-Based Therapies, and Emotionally-Focused Therapy, though further research is required to establish their efficacy .
Low Intensity and Alternative Psychological Interventions
Low intensity psychological interventions, such as brief therapies and self-help approaches (including computer or internet-based programs), have been found to effectively reduce eating disorder symptoms, particularly for binge eating, and can help increase access to care Russell2023Davey2023. However, these interventions may be less likely to achieve full remission compared to high intensity therapies, and more research is needed for their use in children, adolescents, and less common eating disorders .
New and Emerging Approaches
Recent studies have explored novel therapies like Metacognitive Interpersonal Therapy for Eating Disorders (MIT-ED), which targets both eating disorder symptoms and broader psychological functioning, such as personality disorder features. Early results suggest MIT-ED may be as effective as CBT-E for non-underweight eating disorders, with potential added benefits for comorbid personality issues . However, these findings are preliminary and require further validation in larger studies .
Gaps and Future Directions
While CBT and family-based therapy remain the best-supported treatments, there is a need for more research into therapies for anorexia nervosa in adults, avoidant/restrictive food intake disorder, and other less common eating disorders Russell2023Kass2013Bhadoria2010+5 MORE. There is also a need to improve access to effective treatments and to adapt therapies for diverse populations and settings Kass2013Waller2016Wilson2007+1 MORE.
Conclusion
The best psychological therapies for eating disorders are cognitive-behavioral therapy (including enhanced and guided self-help forms) for bulimia nervosa and binge eating disorder, and family-based therapy for adolescents with anorexia nervosa. Interpersonal psychotherapy is also effective for bulimia nervosa and binge eating disorder. Newer therapies and low intensity interventions show promise, but more research is needed to expand effective treatment options and improve outcomes for all individuals with eating disorders.
