COGNITIVE AND SOCIOEMOTIONAL FUNCTIONING AT 4½ YEARS IN CHILDREN BORN TO MOTHERS WHO HAVE RECEIVED TREATMENT FOR SUBSTANCE-ABUSE PROBLEMS WHILE PREGNANT.

Cognitive and socioemotional functioning at 4½ years of age were examined in children born to mothers with substance-abuse problems (n = 22) recruited from residential treatment institutions while pregnant, and then compared to children born to mothers with mental health problems (n = 18) and children from a low-risk group (n = 26). No significant group differences in cognitive functioning were found, but the children born to mothers with substance-abuse problems showed more caregiver-reported socioemotional problems than did the low-risk children, like the children born to mothers with mental health problems. Birth weight had an effect on internalizing problems at 4½ years and mediated the relation between group and socioemotional problems, although not when controlling for caregiver education, single parenthood, and anxiety and depression. At 4½ years, 7 children born to mothers with substance-abuse problems were placed in foster care. These children had lower birth weight and higher caregiver-rated internalizing problems. In addition to emphasizing the importance of the quality of the prenatal environment, this study suggests that families with previous substance abuse are in need of long-term follow-up to address socioemotional problems and enhance further positive child cognitive development. The foster-placed children may be in particular need of long-term follow-up.
