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.
