Prematurity remains a leading cause of motor developmental delays. The Alberta Infant Motor Scales (AIMS) is a useful tool to easily assess motor development. However, during the last decade, cross-cultural differences have been identified regarding the original AIMS norms. Therefore, the aim of this study is twofold: confirm the validity of the AIMS in a preterm population and compare the new Dutch AIMS norms to the original Canadian ones in our Belgian population.
Ninety-six preterm infants were assessed simultaneously on the AIMS and on the Bayley Scales of Infant-Toddler Development (Bayley-III) at age 9-14 months. Concurrent validity was evaluated by correlation analysis. Among these, 89 were assessed on the AIMS at age 3-6 months. Clinimetric properties of both AIMS norms were calculated to compare their ability to detect a motor delay on the Bayley-III at age 9-14 months.
Pearson's coefficient showed an excellent level of correlation between the two scales (r = 0.91). At age 3-6 months, only the 10th Canadian centile showed acceptable properties to predict a significant motor delay. At age 9-14 months, the 5th centile of both norms showed good properties to diagnose a significant motor delay, while only the Canadian norms seems to be sensitive enough to diagnose a mild motor delay.
The new Dutch norms seem to be less sensitive but more specific than the Canadian ones and therefore require adapted cut-offs to diagnose motor developmental delays in a preterm population.
早产仍然是导致运动发育迟缓的主要原因。阿尔伯塔婴儿运动量表(AIMS)是一种评估运动发育的有用工具。然而,在过去十年中,针对原始 AIMS 标准,已经发现了跨文化差异。因此,本研究的目的有两个:在早产儿人群中确认 AIMS 的有效性,并在我们的比利时人群中比较新的荷兰 AIMS 标准与原始加拿大标准的差异。
96 名早产儿在 9-14 个月龄时同时接受 AIMS 和贝利婴幼儿发育量表(Bayley-III)评估。通过相关性分析评估了同时效度。其中 89 名早产儿在 3-6 个月龄时接受了 AIMS 评估。计算了两种 AIMS 标准的计量特性,以比较它们在 9-14 个月龄时在 Bayley-III 上检测运动迟缓的能力。
Pearson 相关系数显示两种量表之间存在极好的相关性(r=0.91)。在 3-6 个月龄时,只有加拿大第 10 百分位数显示出可以预测显著运动迟缓的可接受特性。在 9-14 个月龄时,两种标准的第 5 百分位数都显示出很好的特性来诊断显著的运动迟缓,而只有加拿大标准似乎足够敏感,可以诊断轻度运动迟缓。
新的荷兰标准似乎不如加拿大标准敏感,但特异性更高,因此需要调整截断值来诊断早产儿的运动发育迟缓。
