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 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
