Adolescents' Perspectives on Smartphone Applications for Physical Activity Promotion: insights from Focus Group

Purpose: This study explores how children and adolescents perceive physical activity (PA) and PA apps. We aim to understand their perceptions, past experiences, and expectations of PA and PA apps. Methods: Participants (N=39) aged 11-15 from five European countries: Netherlands (NL), Poland (PL), Portugal (PT), Spain (ES), and Sweden (SWE) participated in the study. They provided insight regarding Behaviour Chance Techniques (BCTs) that enhance app engagement. Results: The results offer valuable insights for creating fun and engaging adolescent PA apps that meet diverse user preferences. They also provide invaluable guidance for designing PA apps that boost adolescents' enjoyment, fun, and engagement while considering a broad spectrum of user preferences. Key BCTs identified as significantly impacting app engagement included self-monitoring, rewards, feedback, social support, action planning, and reminders - preferences and suggestions varied by gender, age, and PA levels. Conclusions: Findings in the present study inform the MOVE4FUN project that contributes to understanding how BCTs promote sustained PA in adolescents. It underscores the pivotal role of personalised app design and a supportive climate in fulfilling individual needs and intrinsic goals. These insights contribute significantly to developing educational tools that encourage regular PA and nurture the holistic development of physically educated citizens.
