Description
We examined the relations between maternal depression, discipline practices, and toddler mental health outcomes, specifically competence and total problem behavior. Ethnicity was considered as a moderator in all analyses. For the first time, ethnicity was considered as a moderator of the heritability of toddler competence and total problem behavior. The data came from the Arizona Twin Project. A subsample containing only Caucasian (66%) and Hispanic (34%; 87% of Mexican descent) participants was used. Primary caregivers (>95% mothers) reported on levels of maternal depression, discipline practices, and their twins' competency and problem behaviors. It was hypothesized that maternal depression would be associated with less competency and more problem behaviors in toddlers; inductive discipline practices would be associated with higher competency and fewer problem behaviors; and punitive discipline practices would be associated with lower competency and more problem behaviors. Ethnicity was predicted to moderate only the relation between discipline practices and toddler mental health. Consistent with predictions, maternal depression predicted less competency and more problem behaviors, and inductive discipline predicted higher competency and fewer problem behaviors, while punitive discipline predicted lower competency and more problem behaviors. Ethnicity moderated the relation between maternal depression at 12 months and total problem behaviors. The heritability of competence and total problem behavior varied across the Caucasian and Hispanic samples.

Description
This study investigated whether the patterns of direct association, and of gene-environment interaction (GxE), between family variables (i.e., parenting, family conflict, and attitudinal familism) and youth externalizing behaviors differed across racial/ethnic groups. The sample was composed of 772 twin pairs from the Adolescent Brain Development Study (ABCD) and analyses were run on three racial/ethnic groups (White [n=1023], Black/African American [n=220], Hispanic [n=152]; Mage=10.14 years). Youth reports of parental warmth, parental monitoring, family conflict, parent-reported attitudinal familism, and parent reports of youth externalizing behaviors were collected at baseline when children were 10 years old. Regression analyses tested the direct association between the family variables and youth externalizing behaviors, and moderated heritability models tested for GxE. Family conflict was associated with more externalizing behaviors for White youth, and parental warmth was associated with fewer externalizing behaviors for Hispanic youth. Parental attitudinal familism composite and familism support were associated with fewer externalizing behaviors for Black youth but more externalizing behaviors for Hispanic youth. We found no effects for parental monitoring, familism obligations, and familism referent on youth externalizing behaviors. Additive genetic and non-shared environmental influences explained the variance in youth externalizing behaviors across all groups. For White youth, parental warmth, parental monitoring, and familism support moderated additive genetic (A), shared-environmental (C), and non-shared environmental (E) influences on externalizing behaviors, and familism obligations moderated C and E influences. Results from exploratory moderated heritability analyses conducted for the Black/African American and Hispanic samples are discussed. Altogether, these findings highlight the multiple avenues through which the family context can impact the development of youth externalizing behaviors, and reinforce the need to examine how these relations differ across racial/ethnic groups.
