PURPOSE
This study examines object permanence development in infants with motor delays (MD) compared with infants with typical development (TD) and in relation to sitting skill.
METHODS
Fifty-six infants with MD (mean age = 10 months) and 36 with TD (mean age = 5.7 months) were assessed at baseline and then at 1.5, 3, and 6 months postbaseline. A scale was developed to measure object permanence (Object Permanence Scale [OPS]), and the Gross Motor Function Measure sitting subsection (GMFM-SS), and the Bayley Scales of Infant and Toddler Development, 3rd Edition (Bayley-III) were administered.
RESULTS
Interrater reliability of the OPS was excellent and correlation between the OPS and Bayley-III cognitive scores was moderately positive. Compared with TD, infants with MD were delayed in development of object permanence but demonstrated increased understanding over time and as sitting skills improved.
CONCLUSION
In children with MD, object permanence, as quantified by the OPS, emerges in conjunction with sitting skill.
目的
本研究旨在比较运动发育迟缓（MD）婴儿与典型发育（TD）婴儿以及与坐姿技能的关系，考察物体永久性发展情况。
方法
对 56 名 MD 婴儿（平均年龄=10 个月）和 36 名 TD 婴儿（平均年龄=5.7 个月）进行基线评估，然后在基线后 1.5、3 和 6 个月进行评估。制定了一个量表来衡量物体永久性（物体永久性量表[OPS]），并对粗大运动功能测量坐姿子部分（GMFM-SS）和贝利婴幼儿发展量表第三版（Bayley-III）进行了测试。
结果
OPS 的评分者间信度极好，OPS 与 Bayley-III 认知评分之间的相关性呈中等程度的正相关。与 TD 婴儿相比，MD 婴儿在物体永久性发展方面存在延迟，但随着时间的推移和坐姿技能的提高，他们表现出了更高的理解能力。
结论
在 MD 儿童中，通过 OPS 量化的物体永久性与坐姿技能同时出现。
