Note. −2LL = −2 log-likelihood, ΔDF = change in degrees of freedom from full model (I), ΔAIC = change in Akaike Information Criterion from full model (I), ACE = model with additive genetic, shared environment, and unique environmental factors included, AE = model with additive genetic and unique environmental factors included, CE = model with shared and unique environmental factors included. Best fitting models are designated in bold text for each section of analyses.
