Abstract Observed infant temperamental difficulty and infant sleep efficiency and sleep variability were examined as predictors of maternal depressive symptoms, maternal sensitivity, and family functioning. Eight observations at 8-months postpartum were used to assess infant temperament, and actigraphy was used to measure infant sleep for 1-week at the time of the 8-month assessment. Structured clinical interviews were used to assess maternal depressive symptoms between 5 and 12 months postpartu...

Abstract Objective Childhood maltreatment is a major risk factor for the development of behavioral problems and poor physical and mental health. Accelerated cellular aging, through reduced telomere length and mitochondrial dysfunction, may be a mechanism underlying these associations. Methods Families with (n = 133) and without (n = 123) child welfare documentation of moderate-severe maltreatment in the past six months participated in this study. Children ranged in age from 3 to 5 years, were ra...

This study examined the moderating role of household chaos in indirect pathways involving domestic violence (DV), parenting practices (punitive discipline and responsive), and preschool children’s internalizing and externalizing symptoms. We hypothesized that high levels of household chaos would amplify links between domestic violence and parenting difficulties, and that parenting difficulties would in turn predict child behavior problems. Participants in this multimethod (survey, semi-structure...

Maternal postpartum depression, maternal sensitivity, and family functioning were examined as predictors of the stability of observed infant temperament over the first 30 months of life (N = 147 families). Eight observations at 8, 15, and 30 months postpartum were used to assess infant temperament. Structured clinical interviews were used to assess maternal depression, and observational assessments were used to assess family functioning and maternal sensitivity. Family context moderated the effe...

Epigenetics processes may play a vital role in the biological embedding of early environmental adversity and the development of psychopathology. Accumulating evidence suggests that maltreatment is linked to methylation of the glucocorticoid receptor gene, nuclear receptor subfamily 3, group C, member 1 ( NR3C1 ), which is a key regulator of the hypothalamus–pituitary–adrenal axis. However, prior work has been exclusively cross-sectional, greatly constraining our understanding of stress-related e...

Serotonin signaling pathways play a key role in brain development, stress reactivity, and mental health. Epigenetic alterations in the serotonin system may underlie the effect of early life stress on psychopathology. The current study examined methylation of the serotonin receptor 2A ( HTR2A ) gene in a sample of 228 children including 119 with child welfare documentation of moderate to severe maltreatment within the last 6 months. Child protection records, semistructured interviews in the home,...
