Background: The escalating pace of academic pressures and social life have intensified mental health challenges among college students, including widespread anxiety and depression. Non-pharmacological interventions, such as exercise therapy, have gained prominence, with 24-Style Tai Chi emerging as a promising mind-body exercise due to its simplicity and potential mental health benefits. However, its effectiveness across various promotion approaches in higher education settings remains underexplored. Objective: This study aimed to evaluate the impact of different 24-Style Tai Chi promotion methods (on-site, online, mixed, and independent practice) on college students' mental health, assess intervention efficacy, and identify an optimal promotion strategy. Methods: A randomized controlled trial (RCT) involving 250 college students from Shandong Sport University was conducted over 8 weeks. Participants were allocated to On-Site Promotion Group (Offline-PG), Online Promotion Group (Offline-PG), Mixed Promotion Group (MPG), Independent Practice Group (IPG), or Control Group (CG). Mental health was assessed using the Self-Rating Anxiety Scale (SAS), Self-Rating Depression Scale (SDS), and General Self-Efficacy Scale (GSES) at baseline, 4 and 8 weeks, and follow-up. Data were analyzed using one-way ANOVA, repeated measures ANOVA (RM-ANOVA), and regression analysis to evaluate intervention effects and participation impacts. Results: Offline-PG (90% attendance) and MPG (84% attendance) showed significant reductions in anxiety (SAS: Offline-PG 34.8 ± 6.3, MPG 36.2 ± 7.0, P < 0.01) and depression (SDS: Offline-PG 33.7 ± 6.9, MPG 34.9 ± 7.2, P < 0.05) by week 8. Online-PG (72% attendance) and MPG demonstrated significant self-efficacy improvements (GSES: Online-PG 36.1 ± 5.2, MPG 35.5 ± 5.6, P < 0.01). IPG (60% attendance) showed no significant changes. ANOVA revealed inter-group differences (SAS F = 6.45, P = 0.004; SDS F = 5.32, P = 0.009; GSES F = 6.74, P = 0.003), with RM-ANOVA confirming time effects. Regression analysis indicated participation strongly correlated with anxiety and depression reductions in Offline-PG (R = 0.62, P = 0.003) and MPG (R = 0.58, P = 0.004) and self-efficacy gains in Online-PG and MPG (R = 0.67, P = 0.002). Conclusion: 24-Style Tai Chi effectively improves college students' mental health, with on-site and mixed approaches excelling in reducing anxiety and depression, and online and mixed approaches enhancing self-efficacy. A hybrid promotion strategy is recommended to optimize participation and outcomes. Registration number: TCTR20250306005; https://thaiclinicaltrials.org/.

Abstract
Background: The escalating pace of academic pressures and social life have intensified mental health challenges among college students, including widespread anxiety and depression. Non-pharmacological interventions, such as exercise therapy, have gained prominence, with 24-Style Tai Chi emerging as a promising mind-body exercise due to its simplicity and potential mental health benefits. However, its effectiveness across various promotion approaches in higher education settings remains underexplored. Objective: This study aimed to evaluate the impact of different 24-Style Tai Chi promotion methods (on-site, online, mixed, and independent practice) on college students' mental health, assess intervention efficacy, and identify an optimal promotion strategy.
