Description

The primary objective of this study is to test a theory-based, micro-randomized trial to determine the optimal state to deliver a message to increase physical activity by determining the probability older cancer survivors will be physically active in the one hour following a messaging prompt. The secondary, exploratory objective is to determine the probability older cancer survivors will experience a pain episode in the 24 hours following their receipt of a message to increase physical activity.
