Clinical Trial Summary

The scientific premise, developed from past work, is that treatment personalized based on idiographic models (termed Network Informed Personalized Treatment; NA-PT) will outperform the current gold-standard treatment (Enhanced Cognitive Behavioral Therapy: CBT-E). The study goals are to (1) develop and test the acceptability, feasibility, and preliminary efficacy of a randomization of NA-PT versus CBT-E and (2) to test if network-identified precision targets are the mechanism of change. These goals will ultimately lead to the very first personalized treatment for ED and can be extended to additional psychiatric illnesses. Specific aims are (1) To collect preliminary data on the feasibility and acceptability of the randomization of NA-PT (n=40) for EDs versus CBT-E (n=40), (2) To test the initial clinical efficacy of NA-PT versus CBT-E on clinical outcomes (e.g., ED symptoms, body mass index, quality of life) and (3) To examine if changes in NA-identified, precision targets, as well as in dynamic network structure, are associated with change in clinical outcomes.

Intervention

Behavioral:
• Personalized Treatment for Eating Disorders
The first three sessions consist of diagnosis and general psychoeducation on EDs and treatment for ED. After mobile-assessment is complete, Session 4 includes psychoeducation on the network-informed model of personalized treatment and 14 sessions (sessions 5-19) are focused on the top three targets (4-5 sessions per target). Session 20 is a termination and conclusion session.
• Cognitive Behavioral Therapy for Eating Disorders
The first three sessions consist of diagnosis and general psychoeducation on EDs and treatment for ED. After mobile-assessment is complete, Session 4 consists of food monitoring, addressing irregular eating, challenging thoughts, making adaptive behavioral changes, and relapse prevention. Session 20 is a termination and conclusion session.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Change in Clinical Impairment using the Clinical Impairment Assessment	The Clinical Impairment Assessment (CIA), a self report measure, is assessed at multiple time points throughout the duration of the study and is used to examine the severity of psychosocial impairment caused by eating disorders. The scores range from 0 to 64 with higher scores indicating more impairment.	Up to 1-Month Follow-Up
Primary	Change in Eating Disorder Symptoms using the Eating Disorder Examination Questionnaire	The Eating Disorder Examination Questionnaire (EDE-Q), a self report measure, is assessed at multiple time points throughout the duration of the study and is used to examine attitudes and behaviors in individuals with eating disorder symptoms. The scores range from 0-6 with higher scores indicating higher severity of eating disorder symptoms.	Up to 1-Month Follow-Up
Primary	Change in Quality of Life using the Quality of Life Scale	The Quality of Life Scale (QOLS), a self report measure, is assessed at multiple time points throughout the duration of the study and is used to examine various domains of quality of life. Scores range from 16 to 112 with higher scores indicating better quality of life.	Up to 1-Month Follow-Up
