Statistical analysis
Statistical analyses were conducted using software R version 4.2.2 (the R Foundation for Statistical Computing, Vienna, Austria). The accepted level of significance for this study was set at 95%. To determine baseline differences between the intervention group and control group, independent t-tests were performed on continuous baseline variables (e.g., age, PSS-10, DASS-21, ORS-4, CISS-SFC, MER), and Chi-squared tests were performed on categorical or nominal variables (e.g., gender, home location, guardian, etc.). To evaluate the efficacy of the intervention, intention-to-treat (ITT) analyses were conducted separately for each outcome [
