简要总结
The goal of this study is test whether a physical activity app intervention compared to wellness text messaging intervention is more acceptable/engaging among Black women who want to increase their level of physical activity.
详细描述
The goal of this K23 aim is to examine the acceptability and feasibility of the 8-week PA4Health intervention compared to a general wellness text program with 3 assessments (baseline, post-intervention [8 weeks] and 6 months). Participants will complete a single counseling session prior to starting the program. They complete an objective measure of physical activity by wearing an accelerometer for one week at each assessment time point. During the intervention, they will provided with a Fitbit wrist tracker, that will be synchronized to the app, to be worn during the 8-week intervention. Participants will be able to set goals for physical activity as well as monitor their progress toward achieving their goals. Following the trial, they will complete self-reports survey as well as objective measures of physical activity. They will also complete a single qualitative interview to assess their experience with the intervention and to provide feedback for modification.

研究组 & 干预措施
Behavioral: PA4Health app physical activity intervention
The arm for the PA4health app intervention consists of six components: 1) Goal setting and monitoring, 2) Tailored motivational messages based on survey data on barriers and facilitators of physical activity, 3) Education, which consists of twenty-two physical activity (PA) related topics, 4) a semi-structured chatroom where 3-5 participants per chatroom interact with one another to receive and provide peer support for PA, 5) Locator, which provides information about community resources (e.g., community parks, museums) based on participant's zip code, and 6) Steps, which allow participant to monitor their daily level of exercise. Participants wear a Fitbit tracker during the program Edit
干预措施: PA4Health app physical activity intervention (Behavioral)
Wellness Text Messaging
Participants set goal for PA and are encouraged to monitor their level of physical throughout the program. They receive a daily wellness related message during the program as a contact control. They also wear Fitbit tracker during the program.
干预措施: Wellness Text Messaging Program (Behavioral)
结局指标
主要结局
System Usability Scale (SUS)--app satisfaction
时间窗: End of 8 weeks
Description: The SUS measures ability of technology software. High levels of usability and acceptability of the app will be determined by a score greater than 70 on the SUS. Information will be used for improvement of the software. Time Frame: 8 weeks study
Metada data collected from app system
时间窗: 8 weeks
This information will inform usage of patterns of participants, including how frequently the logged into the app system and the component of the app the more frequently or less frequently Time Frame: 8weeks
次要结局
- Accelerometer/actigraph data(baseline, 8 weeks, 6-month follow-up)
- Physical activity constructs(baseline, 8 weeks, 6-month follow-up)
- Fitbit data(Participants will wear this device daily during the active phase of the 8-week intervention and also until follow-up/ 6-month follow up)
