Conditions of Poverty, Parent-Child Interactions, and Toddlers' Early Language Skills in Low-Income Families.

Objectives The study examined the relations between parent-child interaction in the first year of life to toddlers' language skills at age 2 years for a sample of children reared in poverty; of specific interest was testing the Family Stress Model, which proposes that the conditions of poverty influence children's language skills through caregiver well-being (e.g., distress, depression) and interaction dysregulation. Methods Participants were from the Kids in Columbus Study, a birth-cohort study of children born to urban families experiencing material hardship. Caregiver questionnaires were collected when the child was 4-7 months to document poverty conditions (maternal hardship, institutional resources), caregiver well-being (depression, distress), and dysregulation in parent-child interactions. The Bayley-III assessed receptive and expressive language skills when the children were 2 years. Results On average, receptive language skills were nearly 1 SD below the normative mean. Path models showed a significant effect of caregiver-child dysregulated interactions on toddlers' language skills, and an indirect effect of maternal distress on parent-child interactions and, in turn, toddlers' language skills. Conclusions for Practice This study confirmed the theoretical Family Stress Model as a viable representation of the effects of poverty on the language skills of toddlers reared in homes experiencing socioeconomic disadvantage.
