Stepwise linear regression analysis was performed separately for each of the outcome variables. Variables included in the analysis were those with sufficient bivariate correlations of r > 0.300 and a p < 0.05 with the respective outcome in the bivariate analyses as shown in Table 5. For the regression analysis significant predictors (*p < 0.05; **p < 0.01) together with the standardized beta values are shown for each of the outcome variables.
