Developmental retardation in infants as a concomitant of physical child abuse

The impact of child abuse on the developmental functioning of infants was investigated. Thirty verified cases of physically abused children were compared to a reference group of 30 nonabused children matched for age, sex, race, and socioeconomic status. Abused children scored significantly lower in terms of cognitive and motor development as measured by the Bayley Scales of Infant Development. Developmental delays on three of the four sectors of the Denver Developmental Screening Test, personal-social, language, and gross motor, were also found in the abused children. There were, however, relatively few item differences between the two groups on the 30 more general behavioral variables constituting the Bayley Infant Behavior Record. Results appear to confirm clinical observation of abused children as developmentally retarded with specific delays in the language and gross motor areas. Although methodologically complex, longitudinal studies are clearly indicated to assess the stability and/or reversibility of the present findings.The author is indebted to John E.
