A Systematic Review of Tai Chi-based Interventions for Positive and Negative Symptoms, Cognitive Functioning, and...

This study aimed to provide a systematic review of Tai Chi interventions in psychosis and their impact on positive and negative symptoms, cognitive deficits and quality of life. There is growing evidence that the mind-body practice of Tai Chi has value in treating and preventing mental health-related problems, such as stress and anxiety. However, it is unclear whether they are effective or beneficial in serious mental illnesses such as psychosis. A systematic review was conducted in accordance with PRISMA guidelines. The review protocol was registered (PROSPERO). The review examined studies which included adults with diagnosed psychotic disorders who participated in treatment studies examining Tai Chi or Qigong interventions using quantitative measures of positive and negative symptoms, cognitive deficits and quality of life. The search was conducted in August 2024. Data were extracted by two independent researchers and analysed using a narrative synthesis approach. Three-hundred and eighty one papers were screened with six studies included in the final review. Publications spanned from 2012-2022. All studies were based in Asia. Tai Chi interventions were acceptable, and well-tolerated. Outcomes indicated small-medium effective sizes in improving negative symptoms, and cognitive deficits. However largely, these improvements were not maintained over time. The current review suggests that Tai Chi is an acceptable, well-tolerated intervention in individuals with long-term psychotic illnesses in Asian populations There is tentative evidence that it may have a positive impact for negative symptoms and cognitive deficits. Well-controlled studies should be encouraged in Western settings.
