Study Overview
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.

Exclusion Criteria
- •Those who are unable or unwilling to provide informed consent, and are unable to see and interact with computer-based questionnaires and educational interventions.
- •Subjects with any of the following conditions who wish to participate in the intervention component of the program but do not have permission from a clinician may be instructed to abstain from specific intervention components, including those who reported 1) a cardiovascular disease event in the past six months, 2) or heart condition, chest pain, dizziness, or other reason not to participate in physical activity, 3) or weight loss surgery in the past two years, 4) are pregnant, or 5) has a BMI over 45.

Outcomes
Primary Outcomes
Implementation of the Deaf Weight Wise Intervention at Partner Sites
Time Frame: Baseline to 18 Months
This outcome measures implementation of the Deaf Weight Wise (DWW) intervention at partner sites, defined as the number of sites that enrolled participants.
Delivery of the Deaf Weight Wise Intervention As Intended
Time Frame: Baseline to 18 Months
This outcome measures the number of partner sites that delivered the Deaf Weight Wise (DWW) intervention as intended, based on predefined fidelity criteria (e.g., delivery by site-based coaches, completion of all planned sessions, adherence to the DWW curriculum). Fidelity was assessed through direct observation of sessions and bi-weekly counselor meetings. All intervention sessions were delivered remotely by NCDHR coaches via Zoom.
Number of Participants Who Did Not Receive the Intervention at Their Partner Site Because of Site Barriers and/or COVID Restrictions
Time Frame: baseline to 18 months
Secondary Outcomes
- Participant-Level Outcome: Mean Difference From Baseline to 6 Months (Pre- to Post-Intervention) in Number of Fruit and Vegetable Servings Per Day as Measured by the Block Fruit-Vegetable-Fiber Screener(Baseline to 6 Months (Pre- to Post-Intervention))
- Participant-Level Outcome: Mean Difference From Baseline to 18 Months (Pre-Intervention to Post-Maintenance) in Number of Fruit and Vegetable Servings Per Day as Measured by the Block Fruit-Vegetable-Fiber Screener(Baseline to 18 Months (Pre-Intervention to Post-Maintenance))
- Participant-Level Outcome: Mean Difference From Baseline to 6 Months (Pre-Intervention to Post-Intervention) in Physical Activity as Reported on the International Physical Activity Question (IPAQ)(Baseline to 6 Months (Pre- to Post-Intervention))
- Participant-Level Outcome: Mean Difference From Baseline to 18 Months (Pre-Intervention to Post-Maintenance) in Physical Activity as Reported on the International Physical Activity Question (IPAQ)(Baseline to 18 Months (Pre-Intervention to Post-Maintenance))
- Participant-Level Outcome: Mean Percentage Difference From Baseline to 6 Months (Pre- to Post-Intervention) in Self-Reported Body Weight, for Participants With BMI Above Normal Range(Baseline to 6 Months (Pre- to Post-Intervention))
