Note: Models include Sat = saturated model; ACE = full model testing genetic, common, and unique environmental influences compared to the saturated model; AE = model testing genetic and unique environmental influences compared to the ACE model; CE = model testing common and unique environmental influences compared to the ACE model; E = model testing unique environmental influences compared to the ACE model. ep = estimated parameters; minus2LL = minus two log likelihood; df = degrees of freedom; diff = difference; AIC = Akaike’s Information Criterion (lower values indicate a better fitting model); NA = not applicable;

^*Best fitting model.
