Statistical Analysis
The SPSS 24 statistical software package (IBM Corp., Armonk, NY, USA) was used for all data analysis. All data obtained from the questionnaires filled out during face-to-face interviews were evaluated and the means and standard deviations of the numerical data were calculated. Conformity to normal distribution was evaluated with the Kolmogorov-Smirnov test, and categorical and numerical data were compared with appropriate statistical analyses such as the chi-square test, independent t-test, and one-way ANOVA. Values of p<0.05 were considered statistically significant. Reliability scores of each scale were calculated with Cronbach’s alpha, and pre- and postoperative data were compared with paired sample t-tests between the case and control groups.
