R²_corrected = 0.47. B non-standardized regression coefficient, SE standard error, β standardized regression coefficient. p < 0.05. It was determined that the regression model was statistically significant in the multiple linear regression analysis in which the relationship between the patients' pre-operative emotional stress and their pre-operative fear levels was examined (p < 0.001; R2 adjusted = 0.47). It was determined that the factors most associated with pre-operative fear levels were the patients' pre-operative sense of failure (p < 0.001), feeling worried and unhappy, and confusion about the surgery decision (p < 0.05) (Table 5)
