Background: This study examined the association between prenatal cocaine exposure (PCE) and autonomic regulation at 13 months of age. Methods: Measures of respiratory sinus arrhythmia (RSA) were obtained from 156 (79 exposed, and 77 nonexposed) infants during baseline and during tasks designed to elicit positive (PA) and negative affect (NA).…

In this collective case study of caregiver behaviors with their toddlers, two-minute videotaped reading interactions were analyzed using a constant comparative method. Twenty-four caregiver-toddler dyads from a high-risk sample of children prenatally exposed to cocaine were selected from a larger sample because they represented the extremes of…

The continuity of social competence between 36 months and first grade was examined in a sample of children at risk due to prenatal exposure to cocaine (N = 92). Parent report data on social competence were collected at 36 months of age and both parent and teacher report data were collected when children were in first grade. Regression analyses…

This study examined the effects of prenatal cocaine exposure on infant hypothalamic-pituitary-adrenal axis activity and reactivity at 7 months of infant age. Participants were 168 caregiver-infant dyads (87 cocaine exposed, 81 not cocaine exposed; 47% boys). Maternal behavior, caregiving instability, and infant growth and behavior were assessed,…

Children prenatally exposed to cocaine may be at elevated risk for adjustment problems in early development because of greater reactivity and reduced regulation during challenging tasks. Few studies have examined whether cocaine-exposed children show such difficulties during the preschool years, a period marked by increased social and cognitive…
