Note: B is the unstandardized regression coefficient, Std. error is the standard error for this coefficient, and Beta is the standardized regression coefficient; * P-value was <0.05; −0.00 represents a negative value that appears in the table as negative zero because only 2 decimal places were used. Models denoted by letter A indicate that this model tests the direct effect between the independent variable and the outcome variable; models denoted by letter B indicate that this model tests the direct effect between the independent variable and the mediator variable; models denoted by letter C indicate that this model tests the mediating effect between the independent variable and the outcome variable. On several occasions, the R 2 values of model version C are less than those of version A, which is due the listwise deletion of cases missing data on the psychosocial mediator variables
