While traditional interventions have been beneficial for improving health-related quality of life (HRQOL), they typically require significant time and staff resources. To address this, we developed the Roadmap mHealth app, which incorporates resilience-building features based on positive psychology. The app integrates Fitbit^® devices to monitor and visualize steps, sleep, and self-reported mood in the Roadmap app. A two-arm randomized controlled trial (RCT) was conducted to evaluate the impact of Roadmap's positive activities on caregiver HRQOL, measured by PROMIS^® Global Health (physical and mental components), at day-120 post-transplant compared to assessment-only controls.</p><p><strong>Results: </strong>From September 08, 2020 to July 31, 2023, 168 dyads enrolled in the Roadmap study (82 intervention, 87 control).

This 12-week randomised controlled trial evaluated the effects of mobile-application-based performance feedback (MABPF) on physical activity (PA) levels and sedentary time (ST) among 150 staff (aged 47.11 ± 6.46 years) of Nnamdi Azikiwe University, Nigeria. Participants were randomly allocated to three groups: MABPF with hourly reminders (<i>n</i> = 52), MABPF only (<i>n</i> = 50), and control group (<i>n</i> = 48). All groups received education on cardiovascular risk factors and physical activity benefits. PA and sedentary time was assessed at baseline, 6, and 12 weeks using the International Physical Activity Questionnaire-short form. Also, PA was objectively measured using pedometer, and Google Fit. Primary outcomes included step counts, PA levels, and ST.</p><p><strong>Results: </strong>At baseline, 14% of participants demonstrated low PA levels, with no significant between-group differences. Both MABPF intervention groups showed significant improvements in pedometer step counts, Google Fit metrics, walking scores, moderate and vigorous PA, total PA, and ST reduction (<i>p</i> < 0.05 for all comparisons). Between-group analyses revealed that MABPF with hourly reminders was significantly more effective than both MABPF-only and control groups for pedometer step counts (F = 7.336, significantly greater ST reduction compared to control (F = 3.405, <i>p</i> = 0.038).</p><p><strong>Conclusion: </strong>MABPF interventions, particularly when combined with hourly reminders, significantly improved PA behaviours and reduced ST among university staff. These findings support the potential of theory-informed mobile health interventions for promoting PA in workplace settings.</p><p><strong>Clinical trial registration: </strong>Pan African Clinical Trial Registry number, PACTR202405808298188 on 24 May, 2024.</p>","PeriodicalId":72426,"journal":{"name":"BMC digital health","volume":"3 1","pages":"65"},"PeriodicalIF":0.0,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12454610/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145139370","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
