Trial Outcomes & Findings for Text Messaging to Increase Activity in Midlife (NCT NCT04849052)
NCT ID: NCT04849052
Last Updated: 2026-09-02
Results Overview
ActiGraph accelerometers are validated as measures of physical activity and have been used in numerous studies of physical activity in patients with medical illness. In this trial, participants will wear the accelerometer for one week at baseline, 6 weeks, and 12 weeks. We will report change from baseline to 6 weeks and 12 weeks in the average number of minutes of MVPA performed per day.

Participant Flow
Though 116 participants were enrolled in the study, only 80 were randomized. 27 participants were found to be too physically active when wearing the accelerometer, 6 withdrew consent, 2 were lost to follow-up, and 1 was terminated prior to randomization.
Participant milestones
| Measure |
MASTERY Intervention
Participants will complete a positive psychology activity, work towards a physical activity goal, and use a stress reduction technique, then will complete weekly text message sessions. In the first six weeks, participants will review the activities they performed the prior week, be introduced to new material, choose activities to perform that week, and set a new physical activity goal during the text message sessions. In the final 6 weeks, participants will review progress towards prior goals, set new physical activity goals, and choose positive psychology and stress reduction skills to use that week. Finally, over the course of the program participants will complete three brief calls with a study trainer to discuss progress.
MASTERY: In MASTERY, participants will have interactive, two-way text message 'sessions' (5-10 minutes of two-way text communication with an automated text-message program) once weekly for 12 weeks. Furthermore, study trainers will conduct 4 brief calls with participants (Weeks 1, 4, 7, and 12) to introduce the program, assess progress, answer questions, and provide support.

Attentional Control
Participants will receive the same physical activity component noted in MASTERY along with added messages providing education and guidance about physical activity, from our past work. Control participants will not receive PP or midlife-related content.
Attentional Control: Participants in the control condition will also receive text messages once per week. To ensure time matching, the program will have 4 phone check-ins (on physical activity) as in MASTERY.

SECONDARY outcome
Timeframe: Weekly over 12 weeks.To assess the feasibility of the MASTERY intervention the automated platform will record rates of the proportion of text message sessions in which participants respond and set a physical activity goal. The "proportion of text message sessions completed" will be calculated by dividing the number of sessions in which participants respond and set a physical activity goal by the total number of sessions initiated by the text message program.

The International Physical Activity Questionnaire (IPAQ) is a well-validated 7-day physical activity recall assessment for physical activity. Activity will be measured by the number of MET-minutes of moderate or greater activity per week, and change will be assessed by subtracting the baseline score from the 6- and 12-week scores.

The positive affect items on the Positive and Negative Affect Schedule (PANAS), a well-validated scale used in other intervention trials and in patients with medical illnesses, will be used to measure positive affect (Range: 10-50). Change will be calculated by subtracting the score at baseline from the score at 6 and 12 weeks. Higher scores indicate higher levels of positive affect.

MASTERY Intervention
n=34 Participants
Participants will complete a positive psychology activity, work towards a physical activity goal, and use a stress reduction technique, then will complete weekly text message sessions. In the first six weeks, participants will review the activities they performed the prior week, be introduced to new material, choose activities to perform that week, and set a new physical activity goal during the text message sessions. In the final 6 weeks, participants will review progress towards prior goals, set new physical activity goals, and choose positive psychology and stress reduction skills to use that week. Finally, over the course of the program participants will complete three brief calls with a study trainer to discuss progress.
MASTERY: In MASTERY, participants will have interactive, two-way text message 'sessions' (5-10 minutes of two-way text communication with an automated text-message program) once weekly for 12 weeks. Furthermore, study trainers will conduct 4 brief calls with participants (Weeks 1, 4, 7, and 12) to introduce the program, assess progress, answer questions, and provide support.

SECONDARY outcome
Timeframe: Baseline, 6 weeks, 12 weeksPopulation: MASTERY Intervention: 4 participants were included in the analysis at 6 weeks, and 5 were included in the analysis at 12 weeks. Attentional control: 9 participants were included in the analysis at 6 weeks, and 9 were included in the analysis at 12 weeks.
Waist circumference will be measured by nurses at baseline, 6, and 12 weeks. Change will be calculated by subtracting the baseline value from the value at 6 and 12 weeks.

MASTERY Intervention
n=5 Participants
Participants will complete a positive psychology activity, work towards a physical activity goal, and use a stress reduction technique, then will complete weekly text message sessions. In the first six weeks, participants will review the activities they performed the prior week, be introduced to new material, choose activities to perform that week, and set a new physical activity goal during the text message sessions. In the final 6 weeks, participants will review progress towards prior goals, set new physical activity goals, and choose positive psychology and stress reduction skills to use that week. Finally, over the course of the program participants will complete three brief calls with a study trainer to discuss progress.
MASTERY: In MASTERY, participants will have interactive, two-way text message 'sessions' (5-10 minutes of two-way text communication with an automated text-message program) once weekly for 12 weeks. Furthermore, study trainers will conduct 4 brief calls with participants (Weeks 1, 4, 7, and 12) to introduce the program, assess progress, answer questions, and provide support.

Attentional Control
n=9 Participants
Participants will receive the same physical activity component noted in MASTERY along with added messages providing education and guidance about physical activity, from our past work. Control participants will not receive PP or midlife-related content.
Attentional Control: Participants in the control condition will also receive text messages once per week. To ensure time matching, the program will have 4 phone check-ins (on physical activity) as in MASTERY.
