Thirty-seven mothers and fathers were observed in their homes interacting with their 2- and 4-year-old-children at Time 1 and 2 years later. Parental mental state talk to children varied as a function of children's age, the context in which talk occurred, and the gender of the parent. Four-year-old children, with an older sibling, produced and heard more(More)
This study examined associations among maternal sensitivity, mothers' early adversity and the Arginine Vasopressin 1a Receptor (AVPR1A) gene. Early adversity in mothers' background has been found to be associated with lower maternal sensitivity. Animal literature suggests that variation in the AVPR1A gene is associated with parenting quality. The goal of(More)
To assess the measurement invariance of the Center for Epidemiologic Studies Depression Scale (CES-D) 2 months after delivery in 656 English-speaking immigrant and non-immigrant women who had at least one other child under 16 and who gave birth in one of two urban Canadian centers. We also compared levels of depression in these two groups using this scale.(More)
Early life adversity has been associated with hypothalamic-pituitary-adrenal (HPA) axis dysfunction in both children and adults. However, in adulthood, most studies have focused on the effects of early adversity on HPA axis stress reactivity rather than the cortisol awakening response or diurnal cortisol profiles. The goal of this study was to examine the(More)
BACKGROUND Children in stepfamilies and single-parent families exhibit elevated levels of behavioural and emotional problems compared with children in intact (biological) families, but there is variation within and across these family types. AIMS To examine the sources of variation in children's behavioural and emotional problems across diverse family(More)
This study examined the impact of differential-maternal parenting behavior, evaluated as a family-level experience, on children's emotional-behavioral problems. Data come from 3 child development studies: 2,128 four- to sixteen-year-olds (Ontario Child Health Study), 7,392 four- to eleven-year-olds (National Longitudinal Study of Children and Youth), and(More)
This within-family, longitudinal study including biological and stepfamilies investigated mutual influences between marital conflict and children's behavior problems. Children (4 to 17 years; N=296) residing in 127 families drawn from a general population study were investigated at Time 1 and again 2 years later. These nested data were analyzed using(More)
Parent and teacher data for 14,990 children from the National Longitudinal Survey of Children and Youth were used in multilevel analyses to examine the relationship between ethnicity, children's aggression and emotional problems, and parenting. Using parent and teacher report, relationships between ethnicity and child behavior were present but modest. The(More)
This article examines the role of the shared family context in understanding differential parental treatment of children. Child-specific and family-context predictors of differential parental positivity and negativity were examined using multilevel modeling in a population of 8,476 children nested in 3,762 families. Child age was the strongest(More)
OBJECTIVE The purpose of this exploratory study was to examine change in internalizing symptoms from late childhood (age 10) into mid-adolescence (age 15) in a nationally representative sample of Canadian children. The roles of a child's sex, maternal depressive symptoms in late childhood, and their interactions were investigated. METHOD The sample was(More)
