Abstract
Well-justified protocols for interpretation of standardized developmental tests when administered to premature infants are currently unavailable. This study was a retrospective review of 203 charts of premature infants whose development was assessed during their first year of life with the Denver Developmental Screening Test (DDST). Children known to be developmentally normal at one year usually performed normally on the DDST by six months chronological age, whether or not age was adjusted for prematurely. Poorer DDST results were common at five and eight months, probably a phenomenon related to test construction. Multiple regression analysis supported the practice of adjusting age for prematurely; however, a difference between results interpreted according to chronological age and results interpreted according to adjusted ages may improve discrimination of the DDST.
