Clinical Trial Summary

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.

Related Conditions & MeSH terms

• Eating Disorders
• Feeding and Eating Disorders

Intervention

Behavioral:
• Transdiagnostic Network Informed Personalized Treatment
Idiographic network analysis is used to determine individuals' top central eating disorder symptoms. Participants then receive modules to address these specific symptoms.
• Enhanced Cognitive Behavioral Therapy for Eating Disorders
Manualized CBT-E (Fairburn 2008) including regular eating, self-monitoring, and CBT modules implemented flexibly.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Eating disorder symptoms	Eating Disorder Examination Questionnaire 6.0 (EDE-Q) will be used to measure change in eating disorder symptoms. The EDEQ has a minimum global score of 0 and a maximum global score of 132. Higher scores indicate more severe eating pathology.	Up to 18 weeks
Primary	Clinical impairment	The Clinical Impairment Assessment (CIA) will be used to measure change in severity of psychosocial impairment. The CIA has a minimum score of 0 and a maximum score of 48, with higher scores indicating higher levels of impairment.	Up to 18 weeks
Secondary	Psychological comorbidities using Structured Clinical Interview for DSM-5 (SCID-5)	The investigators will be assessing psychological comorbidities using the SCID-5. The SCID-5 is a semi-structured interview used to arrive at DSM-5 diagnoses. Participants will complete the ED, anxiety, depression, mania, psychosis, and suicide modules.	Up to 18 weeks
Secondary	Medical comorbidities using the Health Utilization and Medical Comorbidities	The investigators will measure medical comorbidities (e.g., obesity) using the Health Utilization and Medical Comorbidities measure. This measure does not have a score but rather asks questions about different types of healthcare services and medical conditions and whether the participant has/has used them.	Up to 18 weeks
Secondary	Health service utilization using the Health Utilization and Medical Comorbidities	The investigators will measure health service utilization using the Health Utilization and Medical Comorbidities measure. This measure does not have a score but rather asks questions about different types of healthcare services and medical conditions and whether the participant has/has used them.	Up to 18 weeks
