摘要

The use of chronological or/and corrected age administeringBSITD-III in preterm children was investigated in a sample ofpreterm infants and full-term infants. BSITD-III wasadministered at 12 months corrected age. The performancescores for the three BSITD-III subscales were calculatedaccording to the child’ chronological age and considering theBSITD-III request for correction referring to the 40th week orthe 37th week of gestation. Results indicate that corrected ageshould be used with the cognitive subscale only, not with theMotor nor with the Language ones.
