The correlation between the Alberta Infant Motor Scale (AIMS) and the Peabody Developmental Motor Scales-2 (PDMS-2) has not previously been assessed in Norwegian infants. Our purpose was to investigate the concurrent validity of the AIMS and the PDMS-2 in a group of high-risk infants, and to investigate the predictive validity of the two tests for atypical motor function at 24 months post term age (PTA).
This is a retrospective study of the AIMS and the PDMS-2 administered to infants born preterm with gestational age ≤ 32 weeks (n = 139) who had participated in a randomized controlled trial of early parent-administered physiotherapy. The infants' motor development had been assessed using the AIMS and the PDMS-2 at 6- and 12-months. The primary outcome was PDMS-2 at 24-months PTA. To explore the correlation between the two tests we used Spearman's rho. Bland Altman plots were used to detect if there were systematic differences between the measurements. Receiver-operating characteristics curves were used to calculate area under the curve as an estimate of diagnostic accuracy of the AIMS and the PDMS- with respect to motor outcome at 24 months.
The correlation between the AIMS and the PDMS-2 (total motor and locomotion subscale), at 6 months, was r = 0.44 and r = 0.76, and at 12 months r = 0.56 and r = 0.80 respectively. The predictive validity for atypical motor function at 24 months, assessed using the area under the curve at 6- and at 12- months, was for the AIMS 0.87 and 0.86, respectively, and for the PDMS-2 locomotion subscale 0.82 and 0.76 respectively.
The correlation between the AIMS and the PDMS-2 locomotion subscale, at 6- and 12- months PTA, was good to excellent in a group of infants born preterm in Norway. And the AIMS and the locomotion subscale of the PDMS-2 were equally good predictors for atypical motor outcomes at 24 months PTA. These findings indicate that the AIMS and the locomotion subscale of the PDM-2, could be used interchangeable when assessing motor development in infants at 6- or 12 months of age.

艾伯塔婴儿运动量表（AIMS）与皮博迪发育运动量表-2（PDMS-2）之间的相关性此前尚未在挪威婴儿中进行评估。我们的目的是在一组高危婴儿中研究 AIMS 和 PDMS-2 的同时效度，并研究这两种测试在 24 个月校正胎龄（PTA）时对非典型运动功能的预测效度。
这是一项回顾性研究，对在早产儿中进行的 AIMS 和 PDMS-2 进行了研究，早产儿的胎龄为 32 周（n=139），他们参加了一项早期父母给予的物理疗法的随机对照试验。婴儿的运动发育在 6 个月和 12 个月时使用 AIMS 和 PDMS-2 进行评估。主要结局是 24 个月 PTA 的 PDMS-2。为了探讨这两种测试之间的相关性，我们使用了斯皮尔曼的 rho。Bland-Altman 图用于检测测量值之间是否存在系统差异。受试者工作特征曲线用于计算曲线下面积，作为 AIMS 和 PDMS-2 在 24 个月时运动结局的诊断准确性的估计。
6 个月时 AIMS 和 PDMS-2（总运动和运动亚量表）之间的相关性为 r=0.44 和 r=0.76，12 个月时 r=0.56 和 r=0.80。使用 6 个月和 12 个月的曲线下面积评估 24 个月时的非典型运动功能的预测有效性，AIMS 分别为 0.87 和 0.86，PDMS-2 运动亚量表分别为 0.82 和 0.76。
在挪威一组早产儿中，AIMS 和 PDMS-2 运动亚量表在 6 个月和 12 个月 PTA 之间的相关性良好至优秀。AIMS 和 PDMS-2 的运动亚量表对 24 个月 PTA 的非典型运动结果具有同等良好的预测性。这些发现表明，在 6 或 12 个月龄婴儿的运动发育评估中，AIMS 和 PDMS-2 的运动亚量表可以互换使用。
