Pathways linking prenatal substance exposure with 5-year-olds’ internalizing and externalizing symptoms (Maternal Lifestyle Study) for girls (top) and boys (bottom). Standardized coefficients are only presented for statistically significant paths to aid interpretability. Posterior probabilities of membership in temperament types 1–3 were allowed to covary. Externalizing and internalizing problems were also allowed to covary. Covariates were regressed on each of the key study variables.
