<P> The relationship between abnormal feeding patterns and language patterns and language performance on the BSID - III at 18--22 months among extremely premature infants was evaluated . 1477 preterm infants born at <26 weeks gestation completed an 18 - month neurodevelopmental follow - up assessment including the Receptive and Expressive Language Subscales of the BSID - III . Abnormal feeding behaviors were reported in 193 (13%) of these infants at 18--22 months . It was determined with the help of the BSID - III that at 18 months adjusted age, premature infants with a history of feeding difficulties are more likely to have a language delay . </P> <P> Another more recent study focused on the how the application of the BSID - III was useful in recommending treatments for infants in a Neo-natal Intensive Care Unit follow - up clinic . It assessed if the BSID - III was predictive of a referral for further developmental therapy . Independent sample t - tests were conducted to compare motor performance to recommendations for motor therapy found there was a significant difference in the gross motor scores for those who were and were not recommended for motor therapy . Findings indicated that the factors that influence follow - up recommendations are complex and the test scores alone were not indicative of whether or not a referral was given . </P>
