A Mobile App (CareFit) Supporting Physical Activity for Informal Carers of People With Dementia: Mixed Methods Feasibility and Adaptation Study

A Mobile App (CareFit) Supporting Physical Activity for Informal Carers of People With Dementia: Mixed Methods Feasibility and Adaptation Study

For in-app data collection, data included use and time stamps for users across the app tabs, such as Activity, Planner, Resources, and Sharing. Recruitment flyer for carer participants. For an overview of the qualitative approach, Multimedia Appendix 1 provides the full COREQ (Consolidated Criteria for Reporting Qualitative Research) checklist [31].

Medical Expert Knowledge Meets AI to Enhance Symptom Checker Performance for Rare Disease Identification in Fabry Disease: Mixed Methods Study

Medical Expert Knowledge Meets AI to Enhance Symptom Checker Performance for Rare Disease Identification in Fabry Disease: Mixed Methods Study

As users interact with the app, each response updates the app’s internal differential diagnoses, which in turn refines the subsequent question flow. If the optimized version identifies the correct disease earlier in the process, it can streamline the experience by reducing unnecessary questions and focusing more quickly on relevant diagnostic paths. This could result in a more efficient and satisfying interaction. Our study has several strengths.

Home-Based mHealth Platform (Active-Feet) for Children With Idiopathic Toe Walking: Design, Development, and Acceptability Study

Home-Based mHealth Platform (Active-Feet) for Children With Idiopathic Toe Walking: Design, Development, and Acceptability Study

This study was conducted in three phases: (1) assessment of children with ITW needs for a home-based rehabilitation program (content preparation phase), (2) designing an attractive mobile app for children (app design phase), and (3) evaluating the app from the user’s perspective (app evaluation phase). The development process, from conceptualization to pilot testing of the Active-Feet app, is outlined in Figure 1. A schematic view of the main steps followed in the development of the Active-Feet app.

What to Consider When Developing Multidomain Mobile Health Interventions for Lifestyle Management

What to Consider When Developing Multidomain Mobile Health Interventions for Lifestyle Management

Pilot testing (phase 8 of IDEAS): Once all app features were implemented, we tested its functionality with project team members during a 1-week testing phase. Subsequently, we performed a pilot test with 6 older adults. Their 2-week testing experience yielded valuable insights that we used to further improve the app. Afterward, we conducted a crossover interventional study (N=108) using a mixed methods sequential explanatory approach to investigate the use and implementation of the m Health app.

Usability and Acceptability of an App-Based Approach to Treat Low Back Pain: Preplanned Secondary Analysis of a Randomized Controlled Trial

Usability and Acceptability of an App-Based Approach to Treat Low Back Pain: Preplanned Secondary Analysis of a Randomized Controlled Trial

Participants were randomized into 1 of the following 3 groups: App, Physio+App, or Physio. Participants in the Physio+App group also received access to the app “NOLA” in addition to standard physiotherapy. Only the first 2 groups (App, Physio+App) were included in this preplanned secondary analysis. The intervention duration was 6 weeks for both groups.

Mobile Health Adoption in High-Risk Pregnancies Using Cluster Analysis of Biopsychosocial Outcomes: Observational Longitudinal Cohort Study

Mobile Health Adoption in High-Risk Pregnancies Using Cluster Analysis of Biopsychosocial Outcomes: Observational Longitudinal Cohort Study

The first patient was drawn at random and allocated to the app group, and the others were then assigned in an interleaved manner: the second to the control group, the third to the app group, the fourth to the control group, and so on. Thus, we created two balanced groups—one invited to use the app and the other not invited—without supervision or imposition of use.

The Effectiveness of an App-Based Fitness Program on Self-Perceived Physical Functioning in Older Adults: Randomized Waitlist-Controlled Trial

The Effectiveness of an App-Based Fitness Program on Self-Perceived Physical Functioning in Older Adults: Randomized Waitlist-Controlled Trial

The take-up of the newly developed multicomponent app-based fitness program was reported to be good, with 70% (37/52) of the participants using the app-based program at least once a week and 25% (13/52) using it 4 times per week or more often [25,30]. We thus expected the app-based program to affect self-perceived physical functioning in daily life situations.

Anticipation and Motivation as Predictors of Leisure and Social Enjoyment and Engagement in Young People With Depression Symptoms: Ecological Momentary Assessment Study

Anticipation and Motivation as Predictors of Leisure and Social Enjoyment and Engagement in Young People With Depression Symptoms: Ecological Momentary Assessment Study

Based on feedback from piloting sessions with young people, we revised the activity categories and allocated time for app troubleshooting in our study briefing sessions. We also assessed completion time for questionnaires and participant feedback. We found the daily burden manageable, supporting our decision to retain the questionnaire structure. Participants completed the Mood and Feelings Questionnaire (MFQ; ≥27 cut off for clinical depression) [58]. Higher scores indicate higher depression symptoms.
