Statistical analysis

Data distribution was analyzed based on the Shapiro-Wilk test. The Mann-Whitney U test was used in the between-group variance of the data, which did not show normal distribution. Spearman’s correlation coefficient was used for the evaluation of the correlation between the forms with and without the VR items, as well as for the analysis of total item correlations. Cronbach’s alpha coefficient was used for the evaluation of reliability when the VR items were added to the current questionnaire. Exploratory factor analysis was performed based on equamax rotation, and principal component extraction methods during the analysis of the questionnaire construct when the item was added, and confirmatory factor analysis was conducted based on structural equation modeling (SEM) during the analysis of the construct validity. In the path diagram obtained as a result of confirmatory factor analysis, estimation values are provided. IBM SPSS Statistics 22.0 software (IBM Corp., Armonk, NY, USA) was used for statistical analyses, and LISREL 8.4 (Scientific Software International Inc., Lincolnwood, IL, USA) was used for SEM. All analytical results were reported with α=0.05 significance and a 95% confidence interval.
