Statistical analysis:
Data analysis was performed using the Statistical Package for Social Sciences (SPSS) program version 23 (IBM Inc., New York, USA). Descriptive statistics were employed for analysis. Categorical variables were presented as proportions and frequencies. T-test and One-Way Analysis of Variance (ANOVA) were performed to compare mean scores by demographic and professional variables. P-value of less than 0.05 was considered statistically significant.
