Abstract: | The present study examined the detection of early developmental delays of high‐risk infants by first‐time mothers in a community sample of families (N = 451). About half of the mothers were adolescents at time of childbirth, and two thirds reported household incomes below $20,000 annually. Children were assessed at 12 and 24 months of age on standardized measures of cognitive, language, adaptive, and socioemotional development. According to the Individuals with Disabilities Education Act (PL101‐476) guidelines, about 1 in 4 children was eligible for intervention services at 12 months, and about 1 in 3 children was eligible at 24 months. Despite receiving regular medical services, mothers reported that very few eligible children (2% at 12 months and 9% at 24 months) were identified by medical professionals as having any problems that could interfere with development. Much like medical professionals, few mothers were appropriately worried about development, and the likelihood of expressing concerns was related to mothers' knowledge about infant development. These findings highlight the need for medical providers to frequently screen high‐risk children and for parents to become more knowledgeable about infant development. |
