The control group indicated significantly higher mean HRQOL scores in most domains of the HRQOL before intervention (t = -1.927 to -6.072, p < 0.05). However, 6 months after the intervention, the mean HRQOL scores of the intervention group increased significantly in all the domains of HRQOL (p < 0.05) with an effect size of 0.14 (Eta squared). A comparison of the two groups shows a statistically significant difference (64.72 ± 10.96 vs. 58.85 ± 15.23; t = 4.349. p = 0.001) after the intervention. Age was inversely correlated with some domains of HRQOL; as age increases, HRQOL decreases in those domains. Gender had no significant influence on HRQOL.
