Data analysis SPSS (version 14) was used for the data analysis. Descriptive statistics were used to describe the sample characteristics.A Kolmogorov—Smirnov test (K—S test) was conducted to assess normal distributed data. The independent sample t-test and chi-square or Fisher’s exact tests, were calculated to determine any significant difference in the demographic distributions. In the three groups, analysis of co-variance(ANCOVA) and Kruskal—Wallis were used for parametric and non-parametric data respectively. Paired and independent sample t-tests were used to find differences within and between the two intervention groups.
