Note. AIC = Akaike information criterion values based on univariate biometric variance component models. Var. comp. = variance components estimated from the final multivariate AE model including all eight constructs. Confidence intervals are 95% profile likelihood confidence intervals. Results controlling for gender, age, and age-squared. Data are from MIDUS Time 1.
