ABSTRACT
Aims and Objectives
To evaluate the efficacy of YoungAsthma, a nurse-led, web-based mHealth intervention on asthma control and self-efficacy among adolescents with asthma utilizing decision tree analysis.
Background
Asthma is a prevalent chronic condition in pediatric populations, necessitating sustained management for optimal disease control.
Design
A randomized controlled clinical trial.
Methods
Fifty-four eligible adolescents were randomly assigned to either the intervention group (YoungAsthma + Usual care, n = 27) or the control group (Usual care, n = 27) for 4 weeks. Primary outcomes—asthma control and self-efficacy—were assessed using the Information Form, Asthma Control Test, Self-Efficacy Scale for Children and Adolescents with Asthma. Statistical analyses included Fisher’s exact test, chi-square test, Wilcoxon signed-rank test, Mann-Whitney U test, and Intention-to-Treat (ITT) analysis.
Results
Forty-eight participants completed the study (11% dropout per group). The intervention group exhibited a greater improvement in asthma control than the control group. While both groups showed increased self-efficacy, the intervention group’s improvement was significantly higher. Decision tree analysis identified key predictors, indicating that lower scores were associated with a higher likelihood of remaining in the control group.
Conclusions
Nurse-led, technology-supported interventions significantly enhance asthma control and self-efficacy in adolescents. Decision tree analysis provided valuable insights into key factors influencing asthma control and self-efficacy improvements, identifying subgroups that benefited most from the intervention. Interdisciplinary collaboration facilitated a user-centered approach grounded in Bandura’s Self-Efficacy Theory, offering a data-driven framework for personalized asthma management.
Relevance to Clinical Practice
Decision tree analysis aids in identifying patients who would benefit most, enabling precision-targeted interventions.
Reporting Method
This study was conducted in accordance with Consolidated Standards of Reporting Trials and with the Mobile Health Evidence Reporting and Assessment guidelines.
