All variables in the model have been tested for collinearity by using variance inflation factors (VIFs). All VIFs were < 5.0 indicating that the independent variables are not collinear (Urban and Mayerl, 2006); R2adj. = adjusted R2; β = standardized coefficient; SE = standard error, t = t-value. ∗p < 0.05; ∗∗p < 0.01; ∗∗∗p < 0.001.
