Summary

In this six-week behavioral intervention, sedentary older adults will receive daily health messaging via their smart phone to better understand their daily activities and emotions. Participants undergo structural and functional brain imaging before and after the intervention along with measures of their behavioral, emotional and thinking functions.

Detailed description

This project will obtain data on the effects of a six week intervention designed to increase subjects' motivation to increase their physical activity. Subjects will be randomized into two different conditions to examine the efficacy of self-affirmation + positive messaging versus a control group that receives negative messaging only on changes in physical activity. We will also examine whether any differential physical activity or structured exercise engendered in the two groups is maintained at 3 months post-intervention. Secondary outcome measures will include a battery of cognitive, psychosocial, and neuroimaging measures that are designed to explicate the mechanisms that underlie motivation effects for physical activity in sedentary older adults.
