Study Summary
The purpose of this micro-randomized trial is to evaluate the effects of 7 types of intervention messages targeting specific behavior change techniques (i.e., BCT messages) delivered in "just-in-time" (JIT) moments on daily achievement of weight-related behavioral goals among n=201 young adults with overweight and obesity, participating in a digital, mobile comprehensive lifestyle intervention. "Just-in-time adaptive interventions" (JITAIs) are an alternative to the "one size fits all" approach of mobile intervention development that can provide tailored, real-time messaging and support for young adults.
Primary Outcome
Each observation corresponds to a microrandomization decision point; the reported value reflects the outcome measured within that unit. Among the randomization observations in which the participant had not yet weighed, this outcome is the number of observations in which the daily weighing goal was met after receiving or not receiving a message and before the end of the day. Observations are accumulated across participants and across time. On the day of randomization, a dichotomous outcome of whe
