About this study
Official title: Deaf Weight Wise 2.0: Clinical Trial of a Healthy Lifestyle Intervention With Deaf Adults Ages 21 to 70
The purpose of the Deaf Weight Wise 2.0 (DWW 2.0) study is to test an evidence-based, comprehensive program to modify obesity-related health behaviors with Deaf people ages 21 to 70 who use American Sign Language (ASL) as their primary language. Participants will be randomized to one of four arms: immediate intervention vs. intervention delayed one year, and in-person group intervention vs. individual intervention delivered via videophone. The investigators' primary hypothesis is that participants in the immediate DWW 2.0 intervention will increase their physical activity and reduce their caloric intake and body weight compared with those in the delayed intervention group (no intervention yet).

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Deaf Weight Wise 2.0Behavioural
Deaf Weight Wise 2.0 is a group or individual intervention lead by trained, American Sign Language fluent Deaf counselors, who utilize an existing evidence-based curriculum that emphasizes healthy eating, exercise, and lifestyle components. It is a behavior change intervention that uses motivational interviewing techniques 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 Curriculum includes group exercise activities ("Do It!"), experiential learning activities ("Try It!" such as learning how to read a nutrition label or modify a recipe to make it healthier), and group activities related to food preparation or sampling healthy foods ("Taste It!"). Self-monitoring using daily food diaries and weekly "weigh-ins" is also a key component. The intervention also includes a 6-month follow up and maintenance phase.
| Study group | Role | What they receive |
|---|---|---|
| Immediate Group Intervention | Experimental | This arm will receive the DWW 2.0 Group intervention in Year 1 of the clinical trial. The group intervention will consist of groups of approximately 6-8 subjects who meet together for 16 weeks, for two hours each week. A trained, deaf, American Sign Language (ASL)-fluent DWW 2.0 counselor will lead the sessions. Subjects will be asked to complete a daily food and physical activity diary during the course of the 16-week intervention. Each intervention session will include a weigh-in, group sharing and problem solving, discussion of a weight management topic, which may include watching a powerpoint presentation and/or video; and a discussion on goal setting and action planning for the next week. Receives: Behavioral: Deaf Weight Wise 2.0 |
| Immediate Videophone Intervention | Experimental | This arm will receive the DWW 2.0 Individual Videophone intervention in Year 1 of the clinical trial. The participant and their intervention counselor will have one-on-one sessions that take place via videophone (like a Skype call), for one hour each week. Each session will be led by a trained deaf, ASL-fluent DWW 2.0 counselor and will be held at a scheduled appointment time that is agreed upon by the subject and the counselor. Subjects will be asked to complete a daily food and physical activity diary during the course of the 16-week intervention. Each intervention session will include a weigh-in, personal sharing and problem solving, discussion of a weight management topic, which may include watching a powerpoint presentation and/or video; and a discussion on goal setting and action planning for the next week. Receives: Behavioral: Deaf Weight Wise 2.0 |
| Delayed Group Intervention | Other | This arm will receive the DWW 2.0 Group intervention in Year 2 of the clinical trial. The group intervention will consist of groups of approximately 6-8 subjects who meet together for 16 weeks, for two hours each week. A trained, deaf, American Sign Language (ASL)-fluent DWW 2.0 counselor will lead the sessions. Subjects will be asked to complete a daily food and physical activity diary during the course of the 16-week intervention. Each intervention session will include a weigh-in, group sharing and problem solving, discussion of a weight management topic, which may include watching a powerpoint presentation and/or video; and a discussion on goal setting and action planning for the next week. Receives: Behavioral: Deaf Weight Wise 2.0 |
| Delayed Videophone Intervention | Other | This arm will receive the DWW 2.0 Individual Videophone intervention in Year 2 of the clinical trial. The participant and their intervention counselor will have one-on-one sessions that take place via videophone (like a Skype call), for one hour each week. Each session will be led by a trained deaf, ASL-fluent DWW 2.0 counselor and will be held at a scheduled appointment time that is agreed upon by the subject and the counselor.

What is being measured
The primary outcome is the main question the study is designed to answer.
Change in Body Weight (kg)
measure mean change = 6-month weight - baseline weight, for the immediate and delayed intervention groups (change from pre to post intervention).
Measured: 6 month weight (kg) - baseline weight (kg)
Change in BMI (Body Mass Index)
measure mean change = 6-month BMI - baseline BMI, for the immediate and delayed intervention groups (change from pre to post intervention).
Measured: 6-month BMI - baseline BMI
Change in Physical Activity
change in amount of physical activity = 6-month MET-minutes/week - baseline MET-minutes/week (change from pre to post intervention), using the International Physical Activity Questionnaire. IPAQ score is a continuous measure and reports median MET-minutes per week (a combination of walking met-minutes/week + moderate activity MET-minutes/week + vigorous activity MET-minutes/week).
Measured: 6-month MET-min/wk - baseline MET-min/wk

What does the primary outcome measure?
Change in Body Weight (kg) (time frame: 6 month weight (kg) - baseline weight (kg)). The study lists 3 primary outcomes in all. It is what the study was designed to measure, not a finding.
