Monday-Focused Tailored Rapid Interactive Mobile Messaging for Weight Management 2 (M-TRIMM2)
調査の概要
状態
詳細な説明
The specific aims of this research project are to:
- Develop a targeted delivery system for mobile health messages which focused on improving physical activity and diet, and setting healthy resolutions each week.
- Deliver the M-TRIMM intervention, which encourages healthy behavior and the weekly renewal of health resolutions.
- Evaluate the effectiveness of this intervention on individuals' weight loss, self-efficacy, and motivation to sustain changes in lifestyle behaviors.
- Assess the benefit of receiving the message content only (in a paper document), versus a scheduled weekly delivery via mobile messaging.

実験的：Intervention Group - Receiving Text Messages
The 16-weeks text-messaging intervention centered around 8 goal topics: eating only when hungry, increasing PA, eating a lower fat diet, eating less sugar and reducing calories from beverages, exercising more, eating a balance diet, portion control, and making healthier food choices in social situations. Messaging Sun evening: asked to pick 1 of 3 goal topics Mon morning: received a goal to focus on for the week Mon evening: asked whether plans were made to reach the goal Wed morning: received a tip to help reach goal Wed evening: reminded that if having cravings, text "tip" to automatically receive a tip Fri morning: received end of the week congratulations, encouragement to keep goals in mind over the weekend Fri evening: asked for weight, congratulated if lost weight, or encouraged if no weight lost |

After the baseline assessment and the 1st follow-up (~8 weeks post randomization), participants received educational materials regarding physical activity and healthier diets.

アクティブコンパレータ：Control Group - Written Messages
Participants in the control group, received a printed copy of the same messages that the intervention group received. However, the first eight-weeks' worth of messages and craving tips were given after the baseline assessment, and the rest were given after the first follow-up assessment (~ 8 weeks post randomization). The messages for each week were clearly laid out and labeled. Participants were given spaces to record their answers (i.e. to which goal they were selecting for each week). The study staff reviewed the first week's messages together with the study participants to get the participants comfortable with the format that the printed messages were presented in. |

Comparison of satisfaction with the program and suggestions for improvement between intervention and control groups
時間枠：~16 weeks, and ~42 weeks post-randomization compared to baseline
|
Participants completed a questionnaire that included quantitative and qualitative questions. Most of the qualitative questions sought to assess what parts of the program worked well and what could have been done better. For instance, participants were asked for their suggestions about what could be done to improve the M-TRIMM2 program, what messages they liked and did not like, and why they would or would not recommend the program to their friends. The quantitative questions covered a variety of topics, including participants engagement with the program (i.e. whether the participants read the messages they received), how useful messages were in helping participants reach the eight study goals (i.e. eating only when hungry, and exercising more), how helpful the goals were helping participants to achieve weight loss, and whether the program helped participants commit to new goals each Monday during the intervention. |
