Official title

Phase 1 Clinical Trial to Develop a Personalized Adaptive Text Message Intervention Using Control Systems Engineering Tools to Increase Physical Activity in Early Adulthood

Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

Our goal is to develop personalized decision rules for selecting the frequency, timing, and content of messages to promote physical activity. The objective of this project is to evaluate the acceptability and feasibility of two strategies for calibrating decision rules used to send those messages. Participants will wear an activity monitor for the collection of PA data and be randomly assigned to one of two adaptive intervention strategies. The decision rule for each participant will be refined on a monthly basis throughout the 6-month study based upon the accumulating data on how each participant is responding to different messages under different conditions. Our hypothesis is that more intensive intervention strategies will offer a better user experience because the resulting treatments will be experienced as more personalized.
