Table 4.

Percentage (%) mean scores of quality of life (QoL) domains before and after intervention among experimental and control groups. Higher scores denote lower worry, lower impact, higher satisfaction, and better total QoL

Notes:

a

Between-group effect sizes (experimental minus control groups) were adjusted for the results of the experimental and the control groups before the program using analysis of covariance;

b

Willcoxon test was applied to test the significance of the difference between pre- and post-test percentage mean scores.

Abbreviations: M, mean; SD, standard deviation.
