This paper addresses the question of whether corrected age needs to be applied to both the mental and motor development of preterm infants during the whole of the first year. A neglected problem in this respect is that a precise developmental index cannot be found with very low or very high raw scores. Using an alternative measure of performance (age equivalent deviation score), 36 preterm infants without serious medical or neurological problems were compared with 21 full-term infants on the Dutch version of the Bayley Mental Scale at the corrected ages of 12, 18, 24, 39 and 52 weeks and the Psychomotor Scale at 24, 39 and 52 weeks. Our findings suggest that full correction should be used in assessing the mental development of relatively healthy preterm infants during the second half of the first year. Assessments at earlier ages seem to overestimate the mental abilities of preterm infants, thus indicating that partial correction should be applied at these ages. For motor development during the second half of the first year a partial correction would seem more appropriate. The clinical implications of our findings are discussed.
本文探讨了在整个出生后的第一年中，校正年龄是否需要同时应用于早产儿的智力和运动发育。在这方面一个被忽视的问题是，对于极低或极高的原始分数，无法找到精确的发育指标。使用一种替代的表现测量方法（年龄等效偏差分数），在12、18、24、39和52周校正年龄时，将36名没有严重医学或神经问题的早产儿与21名足月儿在荷兰版贝利智力量表上进行比较，并在24、39和52周校正年龄时在心理运动量表上进行比较。我们的研究结果表明，在评估相对健康的早产儿出生后第二年的智力发育时应采用完全校正。早期年龄的评估似乎高估了早产儿的智力能力，因此表明在这些年龄应采用部分校正。对于出生后第二年的运动发育，部分校正似乎更合适。我们讨论了研究结果的临床意义。
