Effects of Positive Psychological Interventions on Psychological Outcomes, Quality of Life, and Inflammation Biomarkers in Inflammatory Bowel Disease Patients: A Meta-Analysis of Randomized Controlled Trials

This meta-analysis aimed to systematically evaluate the effects of positive psychological interventions on anxiety, depression, stress, mindfulness, hope, quality of life, and disease activity, as well as inflammation biomarkers, in patients with inflammatory bowel disease. Databases such as Cochrane Library, PubMed, EBSCO, Embase, Web of Science, China Biomedical Literature Database, China Knowledge Network, and WANFANG DATA were searched by two researchers from the time of each database’s creation to November 2022. A total of 14 randomized controlled trials (RCTs) with 1,191 patients were included. The results showed that positive psychological interventions were effective in reducing anxiety (standardized mean difference [SMD] = −0.81, 95% confidence interval [CI] [−1.33, −0.30], p = .002), depression (SMD = −0.86, 95% CI [−1.32, −0.41], p = .0002), and stress (SMD = −0.68, 95% CI [−1.05, −0.31], p = .0003), and significantly increased the level of hope (weighted mean difference [WMD] = 3.26, 95% CI [0.84, 5.68], p = .008), mindfulness (SMD = 0.59, 95% CI [0.30, 0.88], p < .0001), and quality of life (SMD = 0.61, 95% CI [0.09, 1.14], p = .02) of patients with inflammatory bowel disease. This suggests that positive psychological interventions can significantly improve positive psychology and reduce negative emotions in patients with inflammatory bowel disease.
