Abstract

Aim: To determine the relationship between the Test of Infant Motor Performance (TIMP) at 3 months and cognitive, language, and motor outcomes on the Bayley Scales of Infant and Toddler Development, Third Edition (Bayley-III) at 2 years of age in high-risk infants born preterm. Method: One hundred and six infants (47 females, 59 males) born at earlier than 31 weeks gestational age were prospectively tested with the TIMP at 10 to 15 weeks after term age and were assessed again with the Bayley-III at 2 years corrected age. Sensitivity and specificity were calculated for various cut points of the TIMP z-score and Bayley-III composite scores of no more than 85. Results: The TIMP z-scores at 10 to 15 weeks of age were significantly associated with all three subscales on the Bayley-III at 2 years of age (p<0.001). Using a TIMP z-score cutoff of −0.5, specificity was relatively high for cognitive (87%), language (88%), and motor (89%) outcomes, but sensitivity was low (cognitive 41%, language 49%, motor 57%). Interpretation: This study demonstrates that the TIMP is related to cognitive, language, and motor outcomes on the Bayley-III at 2 years of age in high-risk infants born preterm. What this paper adds: The Test of Infant Motor Performance (TIMP) predicts Bayley Scales of Infant and Toddler Development, Third Edition outcomes at 2 years of age. The TIMP is relatively good at discriminating between children who will and will not have typical development.
