Rating scale values are given in parentheses. Means and standard deviations refer to the overall data. Coefficients above the diagonal represent Pearson correlation coefficients (r) for the overall data. Coefficients below the diagonal represent Pearson correlation coefficients (r) for the within-group variability.
