What is the purpose of this trial?

Eating disorders (EDs) are serious mental illness: someone dies of an ED every 52 minutes. EDs are highly related to a host of negative outcomes, including public health and individual disease burden, medical and psychological comorbidities, and social determinants of health (SDOH). Treatment response for EDs are suboptimal; there are no evidence-based treatment for adults with anorexia nervosa (AN) or Other Specified Feeding or Eating Disorder (OSFED) and only 50% of adults respond to current evidence based treatments. There are no precision treatments, nor any treatments that consider social context, in existence. Personalized treatments for EDs, that consider social contexts, are urgently needed to improve treatment response and minimize the suffering associated with these illnesses. The investigators' overall goal, extending upon their past work, is to create a treatment personalized based on idiographic (or one person) models (termed Transdiagnostic Network Informed Personalized Treatment for EDs; T-NIPT-ED). The investigators will carry out a two-phase study to systematically characterize individual mechanisms of treatment (Phase I: N=900) and then test the efficacy of each treatment module (Phase II: N=240 drawn from Phase I) compared to the current gold-standard treatment (Cognitive Behavioral Therapy Enhanced: CBT-E). The study goals are to (1) characterize the prevalence of T-NIPT-ED precision treatment mechanisms and medical and psychological comorbidities (e.g., obesity; depression), individual disease burden (e.g., disability), SDOH (e.g., food insecurity), and public health outcomes (e.g., service utilization) specific to these mechanisms, (2) identify if personalized target mechanisms improve when matched to evidence-based treatment modules of T-NIPT-ED and (3) test if change in T-NIPT-ED is associated with improved outcomes (vs CBT-E), including ED outcomes, comorbidities, disease burden, and public health outcomes and if these outcomes are moderated by SDOH. These goals will ultimately lead to the very first precision treatment for ED and can be extended to additional psychiatric illnesses. The proposed research uses highly innovative methods; intensive longitudinal data collected with mobile technology is combined with state-of-the art idiographic modeling methods to deliver a virtual, personalized treatment. This proposal integrates assessment of broad (e.g., SDOH; public health burden) and specific (e.g., ED symptoms) outcomes, to ensure that social context can be integrated into personalization. The proposed research has high clinical impact. Ultimately, this proposal will lead directly to the creation and dissemination of an evidence-based individually-personalized treatment for EDs, as well as will serve as an exemplar for precision treatment development across the entire field of psychiatry.

Is Enhanced Cognitive Behavioral Therapy for Eating Disorders safe for humans?

The research does not provide specific safety data for Enhanced Cognitive Behavioral Therapy for Eating Disorders, but it is a widely studied and used treatment approach for eating disorders. ^{1 2 3 4 5}

What makes the Transdiagnostic Network Informed Personalized Treatment for Eating Disorders unique compared to other treatments?

This treatment is unique because it uses a personalized approach based on individual symptom networks, which helps address the diverse ways eating disorders can present in different people, potentially improving treatment outcomes. ^{1 2 6 7 8}

What data supports the effectiveness of the treatment Enhanced Cognitive Behavioral Therapy for Eating Disorders?

Recent studies suggest that Enhanced Cognitive Behavioral Therapy (CBT-E) is promising for treating eating disorders, including bulimia nervosa, by addressing fears related to food and body image. However, up to 44% of individuals with bulimia may experience worsening symptoms after standard CBT, indicating a need for personalized approaches like CBT-E. ^{1 2 3 6 9}

Published Research Related to This Trial

Cognitive Behavioral Therapy (CBT) and Interpersonal Psychotherapy (IPT) both effectively influenced the relationships among symptoms of Binge-Eating Disorder (BED) in a study of 392 adults, indicating that both treatments can be beneficial.

The symptom of shape concern was identified as the most strongly interconnected and significantly predicted remission indicators, suggesting it could be a key target for future interventions in treating BED.

In a study of 122 patients with eating disorders, it was found that changes in cognitions about body shape are crucial for symptom improvement, with overvaluation of shape being a key predictor of other symptoms.

The analysis revealed different symptom change processes based on childhood maltreatment history, suggesting that tailored therapeutic approaches may be necessary for individuals with such backgrounds to reduce dropout and relapse rates.

In a study of 143 individuals with eating disorders, imaginal exposure therapy showed promise in reducing fears related to weight gain and eating, which are central to ED symptoms.

The research identified that targeting fears of weight gain and the consequences of eating may lead to the most significant improvements in eating disorder pathology, suggesting these fears are optimal focus areas for therapy.

Eating Disorder Symptom and Fear Change Trajectories During Imaginal Exposure Therapy: A Slope Network Analysis. Nicholas, JK., Cusack, CE., Levinson, CA.[2023]

In a study of 56 participants with bulimia nervosa undergoing 16 sessions of cognitive behavior therapy (CBT), specific patterns of change in eating disorder symptoms were identified that can predict worsening symptoms after treatment.

Individuals who showed a rapid increase in binge eating frequency were more likely to experience a recurrence of compensatory behaviors, suggesting that monitoring these trajectories can help personalize treatment for better long-term outcomes.

Participants in the study valued the expertise and empathy of therapists specializing in eating disorders, which enhanced their experience of Cognitive Behaviour Therapy (CBT-E).

Key benefits of CBT-E included gaining insight into the cycles that maintain their eating disorders and experiential learning, while challenges included the difficulty of changing long-standing behaviors and beliefs both immediately and over time.

In a study of 105 patients with eating disorders undergoing enhanced cognitive behavioral therapy (CBT-E), those who showed a rapid response within 4.6 weeks had significantly better treatment outcomes, including lower eating disorder symptoms and higher rates of full remission.

Rapid responders required fewer treatment sessions compared to nonrapid responders, highlighting the importance of early improvement in therapy for achieving optimal results, although nonrapid responders still showed significant symptom improvement overall.

A ten-session cognitive behavioural therapy (CBT-T) for transdiagnostic eating disorders showed significant improvements in eating disorder cognitions, behaviors, quality of life, and negative affect among 52 patients treated by trainee psychologists, with medium to large effect sizes observed from baseline to post-treatment and at follow-ups.

The study indicates that CBT-T can effectively address barriers to treatment, such as cost and access, with a comparable attrition rate of 38.5% to other treatment studies, suggesting it is a viable option for patients with eating disorders.
