Evaluation of YouControl-AFib, a mHealth Application for Persons With Atrial Fibrillation

August 12, 2025 updated by: University of Wisconsin, Madison

Implementation of the YouControl-AFib mHealth Application (Pilot Version) to Improve Physical Activity in Persons With Atrial Fibrillation

This study is being done to establish the feasibility of performing a clinical trial using a mHealth application named YouControl-AFib designed to improve the cardiovascular health of persons with atrial fibrillation. The study will obtain feedback on the app design to inform future versions and will collect preliminary data to support proof-of-concept and potential effect sizes for future trial design.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

Primary Objective

  • To effectively recruit participants for a clinical trial and obtain user feedback on the mHealth app using the Mobile App Rating Scale and focus group sessions.

Secondary Objectives

  • To evaluate the impact of the YouControl-AFib mHealth app (pilot version, 3 months of use) on physical activity in persons with atrial fibrillation.
  • To obtain several additional functional and disease specific endpoints that will help establish possible effect sizes to be evaluated more formally in subsequent versions of the mHealth application.
  • To obtain user feedback on the mHealth app using the Mobile App Rating Scale and focus group sessions.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Average Number of Participants Recruited Per Month
Time Frame: up to 5 months
up to 5 months
Maximum Number of Participants Recruited Per Month
Time Frame: up to 5 months
up to 5 months
Mobile App Rating Scale Scores
Time Frame: 3 months
Mobile App Rating Scale contains several subscales that will each be scored on a scale of 1-5; B-functionality, C-aesthetics, and D-information. Higher scores indicate high levels of functionality, aesthetics, and information quality.

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.

Time Frame: baseline, 3 months
Life's Essential 8 score (LE8) is a composite score between 0-100 that assesses a participant's adherence to 8 lifestyle recommendations with improve cardiovascular health: diet, physical activity, smoking habits, body mass index, cholesterol, blood glucose, and sleep duration. Higher scores are indicative of higher adherence to healthy lifestyle.

Time Frame: baseline, 3 months
baseline, 3 months
Change in ECG-age after using the mHealth app for three months
