|
Health Condition(s) or Problem(s) studied
|
|
Accelerometer wear time
Feasibility of SMS reminders as a means to improve accelerometer wear time.
|
|
Intervention(s)
|
Group 1: Succinct reminder condition: “Good morning! Remember to put on the activity monitor. Thanks!”. Reminder sent on six consecutive mornings.
Group 2: Reminder and rational justification: “Good morning! Because the data gathered will help produce very important scientific knowledge, remember to put on the activity monitor. Thanks!”. Reminder sent on six consecutive mornings.
Group 3: A non-randomised control group of participants who decide to opt out of reminders.
|
|
Primary Outcome(s)
|
1. The number of days on which participants wear the accelerometer, i.e.: provide valid activity data (days of =10 hours of activity data).
2. Total wear-time.
|
|
Secondary Outcome(s)
|
|
Feasibility of using SMS and SMS content acceptability as a part of an RCT, measured with a survey asking about satisfaction with SMS content and fidelity to the intervention (how often the SMS was opened and read in the morning). We also hypothesize the arm receiving reasons to comply would have lower dropout rates in the main study.
