A Phase 3 interventional study of PA4Health app physical activity intervention and Wellness Text Messaging Program in Physical Activity, sponsored by Stony Brook University. Active, not recruiting at 1 site in United States. Open to female participants aged 18 Years to 64 Years, including healthy volunteers. Per ClinicalTrials.gov, last updated 2025-09-03.

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.
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.

. physical limitations to PA engagement
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
Behavioral: PA4Health app physical activity intervention
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.

Also known as: Behavioral PA4Health app physical activity intervention, PA4Health
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.
System Usability Scale (SUS)--app satisfaction
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
Time frame: End of 8 weeks
Metada data collected from app system
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
Time frame: 8 weeks
Accelerometer/actigraph data
Actigraph data will be analyzed to explore potential changes over time objectively collected min/week of MVPA
Time frame: baseline, 8 weeks, 6-month follow-up
Physical activity constructs
Assess changes in theoretical related constructs for physical activity, Stages of Change, Self-efficacy for Exercise, Physical Activity Enjoyment. Changes in mean scores from baseline to end intervention (8 weeks) will be assessed. Additionally changes in mean scores for these measures from end of intervention (8 weeks) and 6 month follow-up after controlling for baseline will be be explored.
Time frame: baseline, 8 weeks, 6-month follow-up
Fitbit data
Fitbit data will be explored to estimate the effect of the intervention on mean steps/week over time
Time frame: Participants will wear this device daily during the active phase of the 8-week intervention and also until follow-up/ 6-month follow up
