Dosing Physical Activity Among Older Cancer Survivors Who Experience Chronic Pain: a Micro-randomized Trial

An Adaptive Design for Dosing Physical Activity Among Older Cancer Survivors Who Experience Chronic Pain: a Micro-randomized Trial

The purpose of this study is to assess the best time to deliver a message to increase physical activity and how often participants will experience a pain episode in the 24 hours following their receipt of a message to increase physical activity.

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.
