The purpose of the National Cancer Institute (NCI) funded randomized controlled study is to develop and evaluate a text message (SMS) based weight loss intervention to 309 overweight or moderately obese English and Spanish speaking adults ages 21 - 60. The investigators propose that participants randomized to the intervention arms will lose significantly more weight than those participants randomized to the control group.
The SMS based intervention will be developed through formative research including focus groups, cognitive interviews, and a pilot test of a Spanish version of mDIET. The focus groups will be conducted with both English and Spanish speaking men and women to 1) learn more about the content areas to be addressed in the intervention including physical activity and sedentary behaviors to expand on previous research; 2) learn more about assessing equivalence and compatibility in intervention messages in English and Spanish; 3) identify the most culturally and linguistically appropriate messages; 4) assess text message use; 5) identify factors that influence food and physical activity decisions; and 6) identify health messages that Latinos see as most understandable, credible, and persuasive, cognitive interviews, and a pilot test of a Spanish version of mDIET. The cognitive interviews will be conducted in Spanish and will help inform translation of study materials (text messages and measures) from English to Spanish. An 8-week pilot test of the Latino (Spanish language) mDIET will be conducted to ensure that the text messages and SMS system works as expected in terms of usability and acceptability.
The randomized controlled trial will be a 12-month intervention with 309 study participants. Participants will be randomized to one of three groups: SMS-only, SMS plus phone counseling, and a control group (Details of the study arms are discussed in another section). The goals of the intervention groups (SMS-only and SMS plus phone counseling) include: 5% weight loss, 500 k/cal per day deficit through reduced caloric intake and increased energy expenditure, 12,00 steps through the use of a pedometer, and a reduction in sedentary behaviors. Participants will receive daily text messages, self-monitoring tools, and brief health promotion printed or wed materials on physical activity, nutrition, or other weight loss related topics. Participants will complete physiological and survey measures at baseline, 6 months, and 12 months to assess weight (BMI), physical activity and diet behaviors, psychosocial behaviors, environmental factors, and exposure and satisfaction with the program.

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| SMS Only | Experimental | The SMS only group will receive hints, tips, strategies, and questions related to weight loss behaviors, physical activity, nutrition, and motivation. The messages will be "pushed" to participants (i.e. no response needed) and "pulled" from participants (i.e. response is needed). The SMS only group will also receive a brief printed or web based outline on weight loss resources and information. |
|
| SMS + Phone Counseling | Experimental | This group will receive hints, tips, strategies, and questions related to weight loss behaviors, physical activity, nutrition, and motivation. The messages will be "pushed" to participants (i.e. no response needed) and "pulled" from participants (i.e. response is needed). The group will also receive monthly counseling calls from a Health Coach to discuss barriers and solutions and will receive a brief printed or web based outline on weight loss resources and information. |
|
| Control | No Intervention | The Control group will receive a binder with an attractive set of Standard Print Materials related to weight loss that is comparable to what one would receive from community resources such as libraries, magazines and national non-profit or governmental organizations such as 5-A Day, American Heart Association and the like. |
| Name | Type | Description | Arm Group Labels | Other Names |
|---|---|---|---|---|
| mDiet | Behavioral | The goals of the intervention groups (SMS-only and SMS plus phone counseling) include: 5% weight loss, 500 k/cal per day deficit through reduced caloric intake and increased energy expenditure, 12,00 steps through the use of a pedometer, and a reduction in sedentary behaviors. Participants will receive daily "pushed" and "pulled" text messages, self-monitoring tools, and brief health promotion printed or wed materials on physical activity, nutrition, or other weight loss related topics. |
| Measure | Description | Time Frame |
|---|---|---|
| Weight Loss | To evaluate differences from baseline in percent weight loss at 12 months. We hypothesize that, compared to the usual care Standard Print condition differences in weight loss will be significant in both the SMS only (SMS = short message service or text message) and SMS+Phone intervention groups. | 12 months |
| Measure | Description | Time Frame |
|---|---|---|
| Intervention Effects | To assess the intervention effects on weight loss by study group, diet, physical activity and sedentary behaviors, quality of life, and depression | 12 months |
