Study Details

Study Description

Brief Summary

The purpose of this study is to develop adaptive (AI) and micro-incentive (MI) interventions and test them against static (SI) and delayed-incentive (DI) interventions in a 4-arm randomized factorial trial to increase MVPA adoption and maintenance among inactive adults. Using neighborhood walkability and socioeconomic status, participants will be recruited from four neighborhood types: "high walkable/high SES," "high walkable/low SES," "low walkable/high SES," and "low walkable/low SES." We will evaluate synergistic or antagonistic effects of interventions and neighborhood factors on MVPA adoption by 12 months and maintenance by 24 months.

Arms and Interventions

Arm	Intervention/Treatment
Experimental: Static goals with delayed incentives Participants will receive static physical activity goals with delayed, non-contingent incentives	Behavioral: Static Goals Prescribed goals remain the same throughout study Behavioral: Delayed (non-contingent) Incentives Incentives are provided on bi-monthly basis for participation
Experimental: Adaptive goals with delayed incentives Participants will receive adaptive physical activity goals with delayed, non-contingent incentives	Behavioral: Adaptive Goals Prescribed goals change daily based on participant's performance Behavioral: Delayed (non-contingent) Incentives Incentives are provided on bi-monthly basis for participation
Experimental: Static goals with immediate rewards Participants will receive static physical activity goals with immediate rewards	Behavioral: Static Goals Prescribed goals remain the same throughout study Behavioral: Immediate Micro-Incentives Incentives are provided immediately for each goal attained
Experimental: Adaptive goals with immediate rewards Participants will receive adaptive physical activity goals with immediate rewards	Behavioral: Adaptive Goals Prescribed goals change daily based on participant's performance Behavioral: Immediate Micro-Incentives Incentives are provided immediately for each goal attained

Outcome Measures

Primary Outcome Measures

Change in mean ActiGraph accelerometer-derived moderate-to-vigorous physical activity min/day (MVPA min/day) between study arms. [12 months]
Change in mean ActiGraph accelerometer-derived moderate-to-vigorous physical activity min/day (MVPA min/day) across high walkable (vs. low walkable) neighborhoods by 12 months. [12 months]
Change in mean ActiGraph accelerometer-derived moderate-to-vigorous physical activity min/day (MVPA min/day) across high walkable (vs. low walkable) neighborhoods by 24 months [24 months]

Secondary Outcome Measures

Change in mean fitness (VO2max measured by treadmill test) between study arms. [12 months]
Change in self-reported physical activity measured by the International Physical Activity Questionnaire (IPAQ). [12 months]
