The sample size in the study was determined by using type I error, type II error, and standard deviations and the number of sample sizes were 36 for both groups. Nevertheless, forty participants were recruited for the mindfulness meditation group and fifty-six for the control group in order to achieve the study design.

Two-way repeated measures analysis of variance (ANOVA) was used to compare scores on the dependent measures at pre- and post-test (1-month and 3-month follow-up). Independent t-tests were used to calculate intervention effects between pre-treatment and post-treatment for all measurement scales for both the intervention and control groups.
