The effect of expressive writing on Chinese cancer patients: A systematic review and meta-analysis of randomized control trails

Cancer patients in China encounter distinctive challenges stemming from cultural disparities and variations in the healthcare systems. This meta-analysis aimed to provide a synthesis of the expressive writing (EW) interventions delivered to Chinese cancer patients and assess the pooled effect of EW on their well-being. The review adheres to the latest PRISMA 2020 guidelines to ensure transparency and rigour. Randomized control trials (RCTs) published before 1 April 2023, and meeting the inclusion criteria were included. Keywords searching was performed in both English and Chinese electronic databases. Ten RCTs were identified and included in the analysis. The results showed that EW usually encompassed four to six writing sessions; the most common writing themes were ‘emotional expression’, ‘cognitive appraisal’, ‘benefit finding’, ‘coping strategies’ and ‘looking to the future’. The meta-analysis suggested that EW had a substantial impact on reducing anxiety levels (Hedges' g = −1.22, 95% CI [−1.54, −0.90], I2 = 0.00%). It is worth noting that although the results of these studies could not be statistically synthesized, their individual findings suggest that EW may be beneficial in reducing anxiety, self-perceived burden and depressive symptoms, as well as increasing self-efficacy in Chinese cancer patients. In conclusion, this review highlights the importance and effectiveness of Ewin alleviating anxiety among Chinese cancer patients and underscores the potential benefits of incorporating EW into comprehensive care programmes for cancer patients in China. More RCTs are needed to explore the broader impact of EW in China.
