Emotional Availability as a Moderator of Stress for Young Children and Parents in Two Diverse Early Head Start Samples.

Positive parent-child relationship quality is critical for buffering children from the effects of stress on development. It is thus vital to develop interventions that target parent-child relationship quality for families experiencing stress. We examined the moderating role of parent-child relationship quality (as measured by parental emotional availability [EA]) in the intergenerational association between parental adverse childhood experiences (ACEs) and their young children's hair cortisol concentrations (HCCs)-a physiological marker of cumulative hypothalamic pituitary adrenal (HPA)-axis activity. Using data from 127 parent-child dyads collected by two of six ACF-funded Buffering Toxic Stress consortium sites, we tested interaction effects of parental ACEs with parental EA on young children's (Mage = 18.38, SDage = 7.10) HCC. Results revealed curvilinear main effects such that higher parental ACEs were significantly associated with greater HCC and stronger associations occurred at higher levels of parental ACEs. However, this association was moderated by parental EA. Thus, among children with higher parental history of ACEs, children of parents with higher EA had lower HCC compared to children of parents with lower EA. These findings provide support for the risk-buffering and risk-exacerbating role of parent-child relationship quality (e.g., EA) for the transmission of parents' early life adversity on their children's HPA-axis activity, documented here in a racially and ethnically diverse sample of children and parents served by Early Head Start. Findings suggest that intervention and prevention efforts targeting stress response in children of mothers with childhood adversity should also support parents in building an emotionally available relationship with their children.

Parents' adverse childhood experiences and parent-child emotional availability in an American Indian community: Relations with young children's social-emotional development.

This study examined relations among parent adverse childhood experiences (ACEs), parent mental distress, child social-emotional functioning, and parent emotional availability (EA) among parents and children served by an Early Head Start program in an American Indian community. The majority of parents and children in the study were American Indian/Alaska Native. American Indian/Alaska Native communities experience relatively high rates of trauma, socioeconomic disparities, and mental health challenges. In this context, young children may be especially vulnerable to early life stress. Further, a strong body of literature demonstrates the long-term effects of ACEs on individuals' mental health, as well as their child's social-emotional functioning. In this study we examined a model to test the relation of parent ACEs to children's social-emotional functioning, with an indirect effect via a latent "mental distress" variable consisting of parent depression, anxiety, and parenting-related distress. Results supported this model, suggesting that parent ACEs related to children's social-emotional problems by way of parent mental distress. However, when a categorical measure of parent EA was added as a moderator, the model only remained significant in the low EA parent group. These results provided evidence for a "buffering" effect of high parent EA on the relation between parent ACEs, parent mental distress, and children's social-emotional problems.
