Data analysis
Independent samples t test, Fisher’s Exact test, and Chi-square test were used in order to determine the differences between the intervention and the control group in terms of sociodemographic and obstetric characteristics. The Kolmogorov-Smirnov test was used to assess the normal distribution of the data. In addition, Mann-Whitney test was employed for the data that did not show normal distribution in order to identify the differences between the groups in terms of labor pain, labor comfort, and state anxiety. In order to determine the difference between the groups in terms of labor duration, Independent Sample t test was performed. Finally, Spearman’s R Correlation test was used in order to determine the relationship between state anxiety level and comfort level in childbirth.
