Nutritious Eating With Soul Dissemination and Implementation
Study Details
Study Description
Brief Summary
The investigators will conduct a full dissemination and implementation study using a type 2 hybrid effectiveness-implementation design. The investigators will conduct this study in the community and work with two vegan soul food restaurants. The investigators propose to examine the effectiveness and implementation of community-delivered, 3-month NEW Soul program among participants (N=228).
Using a randomized design, the investigators will assess effectiveness of two delivery approaches: (1) In-person, live weekly classes with restaurant vouchers (intervention) or (2) restaurant voucher-only (active control).
The investigators will also conduct a cost-effectiveness analysis of delivering the online intervention plus voucher vs. voucher-only with the outcome of cost/change in weight, healthy eating index, and quality adjusted life year.
Lastly, the investigators will examine the implementation of the NEW Soul study with participants and intervention staff.

Experimental: Intervention The intervention condition participants will be instructed to follow a plant-based diet. The intervention participants will receive weekly group classes for 3 months at a local restaurant and will receive guidance on how to choose foods to meet their nutrient needs that fit within the vegan diet. The intervention participants will receive a voucher each week for a free plant-based meal at the restaurant. |
Behavioral: Plant-based diet
Participants will receive a behavioral intervention on a plant-based diet in partnership with a local restaurant.
|
Active Comparator: Control Participants in the active control condition will receive meal vouchers to the restaurant. The active control condition participants will not receive any instruction to follow a particular diet or support. Participants in this condition will receive all intervention material and attend a class at the end of the study to learn about the intervention diet. |
Other: Voucher only
Participants will receive vouchers to a local restaurant. Participants will not attend nutrition classes but will receive a class at the end of the 12-week study.

Outcome Measures
Primary Outcome Measures
- Changes in body weight [3-months]
Changes in body weight in kilograms
- Changes in diet quality [3-months]
Changes in dietary quality as assessed by the Healthy Eating Index
Secondary Outcome Measures
- Cost-effectiveness [3-months]
The investigators will assess the costs between delivering the in-person intervention plus voucher vs. voucher-only with the outcome of cost per change in participant body weight, healthy eating index score, and quality adjusted life year (QALY). The cost-effectiveness evaluation will also include estimating costs of the intervention itself (e.g., training, delivery, infrastructure).
- Implementation [3-months]
Implementation will be assessed using qualitative data collection with participants via focus groups and restaurant staff leading the intervention via in-depth interviews.
