Clinical Bottom Line
“How could I apply this information?”
As funding for early intervention becomes increasingly difficult to obtain and eligibility for services is scrutinized, it is important for clinicians to use specific assessments that will accurately determine an infant's risk for neurodevelopmental delay. When evaluating infants born preterm with a moderate degree of medical issues and identified social-environmental risk factors, clinicians should use a standardized assessment that has a high sensitivity and specificity for determining developmental delay to justify need for early therapy intervention. At 6 weeks, the Test of Infant Motor Performance (TIMP) has considerably more test items than the Bayley III and identified more infants who scored poorly at 6 weeks in comparison to the Bayley III. Based upon the findings in this article, the TIMP would be the preferred assessment compared with the Bayley III, when evaluating young infants with known risk factors to be certain that infants at potential long-term risk received services.
“What should I be mindful about when applying this information?”
This study did not follow infants past 6 weeks who were identified at risk at this early age with the TIMP; thus, the predictive power of the TIMP for this group is not clear. Divergence between the TIMP and the cognitive and language subtests of the Bayley III was found; therefore, another test would have to be administered to identify delays in those domains. The inclusion criteria identified participants with high-risk socioenvironmental factors; however, there was little mention of the influence of those risk factors on the outcomes.
