Digital InteGrated Behavioral TreatmeNt for Comorbid ObesITy and DeprEssion Among Racial and Ethnic Adults Age 50 and Older

Purpose

The goal of this randomized clinical trial is to test the efficacy of a fully digital intervention, combining the Lumen problem-solving therapy virtual coach for depression management with the Diabetes Prevention Program video-based program for weight loss, among racial and ethnic minorities with comorbid depression and obesity. The study aims include: - Determine the efficacy of the vCare intervention at 6 months. Primary outcomes are weight and depression symptom checklist 20-item (SCL-20) score. - Identify predictors of treatment success, defined by achieving clinically significant weight loss (5%) and depression outcomes (50% decline or SCL-20<0.5), at 6 and 12 months. - Characterize participant experiences and perceptions of the vCare intervention. Eligible participants will be randomized to the early-intervention arm who will receive active treatment for 6 months, followed by maintenance for another 6 months, or the later-intervention arm who will be waitlisted for 6 months and then receive active treatment in the second 6 months.

Arm Groups

Arm	Description	Assigned Intervention
Experimental Early VCare Intervention (6-month active treatment followed by 6-month maintenance)	Participants randomized to the early-intervention arm will receive active treatment for 6 months, followed by maintenance for another 6 months.	Behavioral: vCare Intervention (6-month active treatment followed by 6-month maintenance) During the active treatment, participants will interact with the Lumen virtual coach (for depression management) and watch the GLB videos (for weight loss). Using the Amazon Alexa app on their study iPads, participants will complete 4 weekly Lumen PST sessions initially, 2 bi-weekly sessions, and then 3 monthly sessions during the active intervention. Beginning in week 6, participants will receive automated messages with instructions to view one GLB video a week for 11 weeks. During the maintenance period, participants in the early vCare intervention arm will be able to interact with Lumen for PST coaching when they need to, i.e., "on demand," although they will receive reminders to do so at least once a month. Participants may watch any of the 12 GLB videos again and will receive GLB-themed reinforcement and motivational messages by email every 2 weeks.
Active Comparator Later Waitlist VCare Intervention (active treatment after 6 months)	Participants in the later-intervention arm will be waitlisted for 6 months and then receive active treatment in the second 6 months.	Behavioral: vCare Intervention (active treatment after 6 months) During the active treatment, participants will interact with the Lumen virtual coach (for depression management) and watch the GLB videos (for weight loss). Using the Amazon Alexa app on their study iPads, participants will complete 4 weekly Lumen PST sessions initially, 2 bi-weekly sessions, and then 3 monthly sessions during the active intervention. Beginning in week 6, participants will receive automated messages with instructions to view one GLB video a week for 11 weeks.

Detailed Description

The objective of this project is to test the efficacy of a fully digital intervention, combining the Lumen problem-solving treatment (PST) virtual coach for depression management with the Diabetes Prevention Program (DPP) video-based program for weight loss. This integrated intervention is named vCare. Patients self-identified as a racial or ethnic minority with depression and obesity will be enrolled from a large minority-serving academic medical center in Chicago. In this fully remote clinical trial, participants will receive a study iPad, a wireless weight scale, and a wearable activity tracker. Eligible participants who complete baseline assessment (N=440) will be randomly assigned in 1:1 ratio to receive the vCare intervention early (for 6 months of active treatment and 6 months of maintenance) or later (for 6 months waitlist control and 6 months of active treatment). Participants in either the early- or later-intervention arm will be assessed at 6 and 12 months follow-up. The specific aims of this study are to (1) determine the intervention efficacy to improve the primary depressive symptoms and weight loss outcomes and secondary outcomes (e.g., anxiety, sleep, quality of life, social isolation, loneliness, and psychosocial and cognitive functioning) at 6 months; (2) identify predictors of treatment success, defined by clinically significant weight loss (5%) and depression response (50% symptom reduction) or remission (free of symptoms), at 6 and 12 months; and (3) characterize the experiences and perceptions of intervention participants to inform future adaptation and translation.
