The predicted sample size for comparing parent satisfaction score was found to be 34 children per group (total sample size = 68 children), by assuming an α level of 0.05 and β level of 0.2 (power = 80%). The effect size d was calculated based on the findings of M. Jiang, et al., and the allocation ratio was set at 1.
