Data analysis
The SPSS25 trial version was used for data analysis; descriptive statistics (frequency, percentage, mean and standard deviation) were used to describe the demographic and background characteristics of the participants. Chi-square test, independent samples t-test and Fisher’s exact test were used to determine the homogeneity of two groups in terms of demographic variables. Shapiro–Wilk test was used to determine the normality of the resilience and rejection sensitivity variables (the sum of the two questionnaires). In addition, Levene’s test of equality of error variances fulfilled for both scores of rejection sensitivity and resilience after the intervention. Analysis of covariance was used to determine the difference between two groups regarding rejection sensitivity and resilience scores after the intervention by controlling the pretest scores. The significance level in this study was
