Development and Testing of a Peer-Coaching Model for the Treatment of Eating Disorders

Study Overview
=================
Brief Summary
-----------------
This project includes developing and testing a coaching approach during the treatment of eating disorders. It is expected that with the addition of support outside of regular treatment, caregivers will experience improvements in emotional taxation and patients will strengthen skills necessary for recovery. Twelve weeks of coaching will be incorporated into standard treatment. Randomization will occur placing participants into (1) parent coaching + patient educational materials or (2) parent educational materials + patient coaching.

Detailed Description
-----------------
A total of 70 adolescents with eating disorders between the ages of 12-18 and their parents/caregivers will be enrolled in a randomized-controlled trial comparing parent coaching/patient education to parent education/patient coaching. Measures will include demographics, vitals, parent and patient self-efficacy, quality of life, illness related distress/impairment, and changes in eating disorder symptoms and severity. During a screening and consenting visit, participants will complete assessments including height, weight, demographics, and interview questions to determine inclusion/exclusion criteria and eating disorder diagnoses. At baseline, patients and parents will complete online questionnaires via a REDCap interface, measuring self-efficacy, quality of life, and illness related distress/impairment. During the intervention, participants will attend standard therapy sessions for the treatment of eating disorders, and patients and parents will be randomized to either have access to a designated coach or weekly educational materials. Patients and parents assigned to coaching will be able to contact their coach outside of their therapy session time for 15-minute coaching calls. Completed calls will be tracked to document engagement with coaching. Patients and parents assigned to weekly education materials will receive a link, which will direct them to YouTube videos related to the skills covered in therapy for that week. They will also receive a link with a few questions to document engagement with each video. Coaching: A coach trained in specific skills targeted to assist in family-based therapy, will be assigned to the parent/patient to be available throughout the 12-week intervention. The coach will available between the hours of 9am - 9pm, Monday - Sunday for a brief 15-minute coaching call. During the call, the coach will remind the parent/patient of family-based skills that can be utilized in vivo to address emerging situations. If a call is running over 15 minutes, the coach will refer them to their primary therapist or emergency services. Educational Materials: A 2-5 minute YouTube video will be distributed to the parent/patient weekly. Videos will incorporate a new skill learned in therapy that week. Follow-up measures will be conducted mid-way through treatment and at the end-of-treatment, and these visits will involve patients and parents repeating the assessments administered during baseline.

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Change in Eating Disorder Recovery Self-Efficacy Questionnaire (EDRSQ) | Changes in patient self-efficacy will be measured using the EDRSQ, which is a 23-item instrument that assesses self-efficacy with eating disorder behaviors and attitudes. Total scores range from 1-5 with higher scores indicating greater self-efficacy. Changes in self-efficacy will be calculated using the baseline and 12-week scores from the EDRSQ. | Baseline and 12 weeks | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Change in Parents Versus Anorexia Scale (PVA) | Changes in parent efficacy will be measured using the PVA which is a 7-item instrument that assesses parent's level of efficacy with helping their child with an eating disorder. Total scores range from 5-35 with higher scores indicating greater efficacy. Changes in efficacy will be calculated using the baseline and 12-week scores from the PVA. | Baseline and 12 weeks | 
| Change in Depression Anxiety and Stress Scale (DASS) | Changes in patient stress will be measured using the DASS. The DASS is a 42-item self-report measure of negative emotional states with subscales of depression, anxiety, and stress symptoms. Each subscale is scored 0-42, with total scores ranging from 0-126. Higher scores indicate more severe psychological distress. Changes in stress will be calculated using the baseline and 12-week total score of the DASS. | Baseline and 12 weeks | 
| Change in Center for Epidemiologic Studies-Depression (CES-D) | Changes in parental stress will be measured using the CES-D, which is a 20-item self-report measure evaluating depressive symptoms. Scores range from 0 to 60 with higher scores indicating greater impairment. Changes in stress will be calculated using the baseline and 12-week total score of the CES-D. | Baseline and 12 weeks | 
| Change in the Clinical Impairment Assessment (CIA) | Patient impairment is measured using the Clinical Impairment Assessment, which is a 16-item self-report measure of impairment from eating disorders. Responses are scored using 0, 1, 2, or 3 and the score is calculated using the sum of all items. Possible scores range between 0 - 48, with higher scores indicating more impairment and lower scores indicating less impairment. Change in impairment will be calculated using the baseline and 12-week scores from CIA. | Baseline and 12 weeks | 
| Change in weight | Weight will be measured in the EWDP IP clinic by study staff during all study visits. Change in weight will be calculated using the baseline and 12-week measurements. | Baseline and 12 weeks | 
| Number of Contacts with Coach outside treatment visit | Coaching utilization will be measured by tracking the number of contacts to the coach outside of treatment visits. Utilization will be calculated using the sum of contacts throughout the 12-week treatment. | 12 weeks | 
| Number of Treatment visits attended | Coaching utilization will be measured by tracking the number of treatment visits attended. Utilization will be calculated using the sum of treatment visits throughout the 12-week treatment. | 12 weeks |
