Deaf Weight Wise: Community-engaged Implementation Research to Promote Healthy Lifestyle Change With Deaf American Sign Language Users
Study Details
Study Description
Brief Summary
The purpose of the Deaf Weight Wise Implementation Study is to study with diverse partners the approaches and strategies that lead to successful implementation of Deaf Weight Wise (DWW), an evidence-based healthy lifestyle intervention for use with Deaf adult American Sign Language (ASL) users. The implementation hypothesis is that diverse community organizations will successfully implement DWW with their constituents.

Detailed Description
Little is known about health or health promoting interventions in Deaf communities nationally or worldwide. Deaf individuals comprise understudied and medically underserved populations. Access to health services, research, and health information is confounded by communication and literacy barriers. One of the challenges of health research with deaf people is creating survey instruments and interventions that are culturally and linguistically appropriate. The original Deaf Weight-Wise Study (2012-2014) by this study team of the Rochester Prevention Research Center (RPRC): National Center for Deaf Health Research (NCDHR) was the first adequately powered randomized trial of an evidence-based healthy weight/lifestyle intervention to be carried out in Deaf people. Deaf Weight Wise is based on the University of North Carolina's Weight Wise program and represented a pioneering effort to collect new health information and develop intervention tools in a very understudied and underserved minority group. Deaf Weight Wise 2.0 (2017-2019) was built on this research team's experience with the original Deaf Weight Wise trial for ages 40-70, and was an adaptation of the original Deaf Weight Wise curriculum to suit ages 21-70. DWW 2.0 also evaluated the additional component of a one-to-one individual counseling intervention delivered remotely over videophone (like Skype/Zoom) in addition to the group intervention format.
This new Deaf Weight Wise implementation research proposed here will allow this study team to work with community partner organizations, to train them to implement DWW at their own sites. This will fulfill the goal of disseminating DWW broadly to Deaf communities. The study team will conduct research to study the process of implementation of DWW at each site. This advances DWW along the translational spectrum to ensure that DWW is not only a research project, but becomes a sustainable, community-based program.
The study team will conduct an implementation-effectiveness Type 3 research design that is plan, execute and evaluate in collaboration with partners. The study team will adapt and implement DWW with partner organizations at various sites in central and western NY. Each phase of this study, including selection of the intervention topic (obesity and healthy lifestyle), design of study procedures, and development of the informed consent and data collection processes, are based on direct input and feedback from Deaf research team members and Deaf community members.
All aspects of this research will be conducted via virtual video communication platforms.
Screening and enrollment is conducted in American Sign Language by Deaf sign-fluent research staff. Informed consent is an ASL video followed by discussion, question and answer, and check for comprehension in ASL by Deaf sign-fluent research staff. Following informed consent, subjects will have data collection appointments at baseline (pre-intervention), 6-months after baseline (post-intervention), and 18-months after baseline (1 year post-intervention). Data collection surveys are conducted via online ASL video surveys with English text support. Data collection interviews at all data collection points are conducted by Deaf sign-fluent research staff.
Following baseline appointments, a trained Deaf sign-fluent DWW intervention counselor from each implementation site will lead the group intervention via virtual video communication platform, with about 5 participants per group. As additional participants are enrolled, new groups will be formed (rolling enrollment at each site).

Behavioral: Deaf Weight Wise intervention
The DWW intervention consists of groups of 5 subjects who meet together for 16 weeks, 2 hours each week. Group meetings will be held virtually on Zoom. A trained, deaf, ASL-fluent counselor will lead the sessions. Each session includes group sharing, problem solving, discussion of a weight management topic, and goal setting and action planning for the next week. A key principle of DWW is motivational interviewing, in which the counselor acts as a facilitator to help participants identify/recognize their own unhealthy behaviors, help individuals build skills that will promote behavior change, and help group members to support each other to make behavior changes. The maintenance phase starts immediately after the 16-week intervention, and consists of two meetings of the original group via Zoom; one at month 3 and one at month 6 of the maintenance period. Counselors also email participants bi-weekly to check in and provide additional support.

Outcome Measures
Primary Outcome Measures
- Site-level outcome: Implementation of the Deaf Weight Wise intervention at partner sites [Assessed at each site at 18 months after baseline enrollment of participants]
Number of partner sites implementing the DWW group intervention with enrolled participants
- Site-level outcome: Percentage of Deaf Weight Wise intervention groups delivered as intended [Assessed at each site at 18 months after baseline enrollment of participants]
The study team will measure whether the intervention is delivered at each site as intended, as assessed by direct observations of the counselor/group and by bi-weekly counselor meetings
Secondary Outcome Measures
- Participant-level outcome: Mean change from baseline to 6-months (post-intervention) in number of fruit and vegetable servings per day as measured by the Block fruit, vegetable, fiber screener [baseline and 6-months (pre and post intervention)]
The mean difference from pre to post intervention in self-reported fruit and vegetable servings per day (baseline servings/day - follow-up servings/day) as measured by the Block Fruit-Vegetable-Fiber Screener. The Block Fruit-Vegetable-Fiber Screener is a 10-item scale with responses ranging from: (1) Less than 1/week to (5) 2+ a day. Higher scores reflect a better outcome.
- Participant-level outcome: Mean change from baseline to 6-months (post-intervention) in physical activity as reported on the International Physical Activity Question (IPAQ) [baseline and 6-months (pre and post intervention)]
The mean difference from pre to post intervention in self-reported physical activity levels over the past 7 days
- Participant-level outcome: Mean change from baseline to 6-months (post-intervention) in self-reported body weight, for participants with BMI above normal range [baseline and 6-months (pre and post intervention)]
The mean weight change (in kg) from pre to post-intervention, expressed as a percentage of baseline weight, for any participants with a BMI above 24.9 (above normal range)
