β standardized regression coefficient; CI 95 % confidence interval; R ² = proportion of variance. All findings in bold are significant (p < 0.05); otherwise non-significant (ns); standardized robust regression coefficients and confidence intervals from robust maximum likelihood models are presented in each cell with R ² as the estimate of the variance predicted
