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.
