Summary

The global surge in smartphone addiction (SA) represents a critical biopsychosocial risk for adolescents. This study evaluated the efficacy of a 12-week structured badminton intervention in alleviating SA among high school students and explored the psychosocial mechanisms underlying behavioral change using a sequential explanatory mixed-methods design.

Thirty adolescents were randomized into experimental (n=15) and control groups (n=15). The experimental group participated in an "open-skill" badminton program (6 sessions/week, 120-150 min/session) for 12 weeks, while the control group maintained their routine lifestyle. Data were collected via the Smartphone Addiction Scale-Short Version (SAS-SV) and semi-structured interviews. Statistical analysis included paired/independent t-tests and ANCOVA, followed by inductive thematic analysis of qualitative data.

Quantitative findings revealed a highly significant reduction in SA levels within the experimental group (Mpre = 32.27 ± 10.25 vs. Mpost = 24.93 ± 7.13, p\<.001), achieving a very large effect size (d= 1.84). No significant change was observed in the control group (p=.095). ANCOVA confirmed a robust intervention effect, F(1,27)= 52.04, p\<.001, explaining 65.8% of the variance. Qualitative follow-up identified five core themes-life functionality, withdrawal, virtual social orientation, overuse, and tolerance-indicating that badminton served as a "temporal buffer" that enhanced self-regulation and real-world relatedness.

A 12-week structured badminton program is a potent non-pharmacological strategy for mitigating technological dependencies. This research provides an evidence-based framework for utilizing sport-specific interventions to foster adolescent psychological resilience. Furthermore, our findings emphasize that open-skill sports act as a socio-cognitive buffer, reclaiming adolescent attention from digital spaces and fostering a sustainable state of digital well-being.

Interventions

BEHAVIORAL

12-Week Structured Badminton Program

Participants assigned to the intervention group will participate in a structured badminton training program for 12 consecutive weeks. The program consists of six supervised sessions per week, each lasting approximately 120-150 minutes. Each session includes a standardized warm-up (30 minutes), badminton technical training and match play (60-90 minutes), and a cool-down period (30 minutes). The intervention is designed to increase regular physical activity, promote social interaction, and improve self-regulation through participation in an open-skill sport.
