mHealth-based Just-In-Time Adaptive Intervention to Improve Physical Activity Levels of Individuals With Spinal Cord Injury
Temple University
Summary
The overarching goal of this research study is to evaluate a sensor-enabled, just-in-time adaptive intervention (JITAI) strategy to increase and sustain physical activity levels among individuals with spinal cord injury (SCI) in their communities. A primary objective of this study is to evaluate the integration of a JITAI with a web-based physical activity intervention program. We hypothesize that the integration of web-based physical activity intervention program with JITAI will result in significantly higher physical activity levels compared to the standard web-based physical activity intervention program alone. A secondary objective of this study is to extend existing algorithms that use commercial wearable technology to robustly detect physical activity behaviors to facilitate the delivery of tailored just-in-time actionable feedback and physical activity recommendations for individuals with SCI.
Description
The integration of the JITAI, which provides feedback and physical activity recommendations due to sensor-based assessments of physical activity, with a standard web-based physical activity intervention program will be tested via a clinical trial. Specifically, individuals with SCI will be randomized to web-based physical activity intervention program (WI) or web-based physical activity intervention program combined with the JITAI (WI + JITAI). Within the WI + JITAI arm, a micro-randomized trial - a clinical trial design for optimizing mobile-Health interventions - will be used to randomize pa…

Interventions
- BehavioralWI program
This 14-week web-based physical activity intervention (WI) program was developed by the National Center on Health, Physical Activity and Disability. The WI program was developed with guidance from literature and practice in health behavior change and internet-based health promotion programming. The content and features of the WI program include motivational resource, updated weekly resources, and customizable features.
- BehavioralWI Program Reminder
Participants will be provided with reminders to use the WI program
- BehavioralJITAI Goal Setting
Participants will be provided with standard, tailored, or no goal for the day. The goal will focus on recommending minutes of moderate-intensity (or higher) physical activity and a reminder to perform strength exercises.
- BehavioralJITAI physical activity message
Participants will be provided with minutes of moderate-intensity (or higher) physical activity achieved, minutes of physical activity remaining, or no message.
- OtherNotification EMA
Participants will be inquired through an ecological momentary assessment (EMA) if they received a JITAI physical activity message.
