Summary

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.

Conditions

  • Cardiovascular Risk Factor

Interventions

BEHAVIORAL

Digital message (text + image)

Messages can be up to 256 characters of text with an image. "Move more" and "sit less" messages were written to target established cognitive and affective constructs associated with physical activity (e.g., prompts to action plan, guidance for maximizing pleasure by regulating intensity).
