Using Smartphones to Improve Physical Activity Levels of Individuals With Spinal Cord Injury

Официальное название

mHealth-based Just-In-Time Adaptive Intervention to Improve Physical Activity Levels of Individuals With Spinal Cord Injury

Обзор

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.

Подробное описание

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 participants several times a day to various types of tailored feedback and physical activity recommendations.

Aim 1: Evaluate the efficacy of the WI + JITAI compared to the standard WI alone. We hypothesize that the integration of WI + JITAI will result in significantly higher physical activity levels compared to the standard WI alone.

Aim 2: Use a micro-randomized trial design to optimize the delivery of just-in-time physical activity feedback and recommendations in promoting physical activity.

Aim 3: Investigate moderators of the effect of WI + JITAI vs. standard WI alone. Moderators will include age, gender, race/ethnicity, level of injury, function, mobility, pain, and fatigue.

The proposed study will yield novel insights about JITAIs and JITAIs combined with more traditional, WI programs, which will help researchers design engaging physical activity interventions for individuals with disability in the community that may improve their health and quality of life.

Вмешательства

• Поведенческое WI 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.
• Поведенческое WI Program Reminder
  Participants will be provided with reminders to use the WI program
• Поведенческое JITAI 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.
• Поведенческое JITAI 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.
• Другое Notification EMA
  Participants will be inquired through an ecological momentary assessment (EMA) if they received a JITAI physical activity message.
• Другое End of day EMA
  Participants will be inquired, through an ecological momentary assessment (EMA), if they performed aerobic and/or strength exercises for the day.
• Другое Wake up time EMA
  Participants will be inquired, through an ecological momentary assessment (EMA), about the time they plan to wake up next day. This information will be used to provide a goal setting message for next day.
• Другое Weekly PA Information
  Participants will have access to minutes of moderate-intensity (or higher) physical activity performed over the last 7 days.
• Другое Daily PA Information
  Participants will have access to minutes of moderate-intensity (or higher) physical activity performed over the day.
