In this trial, where Tai Chi was taught mattered as much as the practice itself.
An eight-week 24-Style Tai Chi program improved college students’ mental health, but only when participation stayed high. On-site and mixed delivery reduced anxiety and depression, while online and mixed delivery improved self-efficacy. Independent practice showed no significant change.
Quick summary
- What the study found: On-site and mixed promotion produced significant anxiety and depression reductions by week eight; online and mixed promotion improved self-efficacy; independent practice did not significantly change outcomes.
- Why it matters: Delivery design that protects adherence may be the difference between “exercise that helps” and “exercise people quit.”
- What to be careful about: Results track participation; lower-engagement formats may look ineffective even if the activity could help when done consistently.
What was found
In the journal article Comparison of the 24-Style Tai Chi intervention based on various promotion approaches on college students’ mental health: A randomized controlled trial, college students were assigned to on-site, online, mixed, independent practice, or control conditions for eight weeks.
By week eight, the on-site promotion group and the mixed promotion group showed significant reductions in anxiety and depression scores, and these improvements held steady at follow-up.
The online promotion group did not show significant anxiety or depression reductions, but it did show significant gains in self-efficacy. The mixed promotion group also improved self-efficacy.
The independent practice group showed no significant changes across anxiety, depression, or self-efficacy.
What it means
The pattern is simple: formats with higher participation produced broader benefits. On-site and mixed formats had higher attendance than online and independent practice, and participation was strongly correlated with symptom reductions in the on-site and mixed groups.
Self-efficacy is the belief that you can handle challenges and follow through on goals. In this study, online delivery appears especially compatible with building that sense of capability, while mixed delivery supported both symptom relief and self-belief.
Where it fits
Tai Chi is a mind-body exercise that combines slow movement, attention, and breath control. As with other forms of structured exercise therapy, a plausible pathway is reduced physiological arousal plus improved emotion regulation skills, which can support lower anxiety and depressive symptoms.
The results also fit a basic behavior-change reality: the best mental health intervention is the one people will actually do. Delivery isn’t a cosmetic choice; it shapes accountability, social reinforcement, and habit formation.
How to use it
If you run a campus program, prioritize a hybrid plan: on-site sessions to lock in routine and technique, plus online options to reduce scheduling friction. The study’s conclusion explicitly recommends a hybrid promotion strategy to optimize participation and outcomes.
If you are a student, avoid “I’ll just do it on my own” as your default. Choose a format that creates external structure, such as scheduled classes, an online module with tracking, or a mixed approach that makes skipping less likely.
Limits & what we still don’t know
This study links better outcomes to higher participation, but it does not prove which specific ingredients of on-site or mixed delivery caused the change. It also does not tell us how effects compare to other exercise types or to psychotherapy.
We also do not learn which components of self-efficacy improved most, or whether gains translate into academic performance, sleep, or longer-term mental health.
Closing takeaway
Twenty-four-Style Tai Chi helped, but not as a “set and forget” wellness tip. When the program was delivered in ways that kept students practicing, anxiety and depression dropped; when it wasn’t, benefits faded or narrowed to self-efficacy. Design for adherence first, and mental health gains follow.
