Despite the Bayley Scales of Infant Development second edition (BSID-II) are wide used both clinically and in research settings, only a few published studies have been examined their stability over time.
The aim of this study was to examine the stability of mental and motor BSID-II scores over the first three years of life.
All children included in this study were a sample followed up in a study on the susceptibility of the fetus and child to environmental factors. The cohort recruited prenatally in Krakow Poland, included 408 children. The mental and motor scales of BSID-II were administered to infants at the end of 12th, 24th and 36th month of life. Stability of the test scores from first to second and third assessment was evaluated using the Pearson's correlation coefficient calculated for the entire group of infants, and for the each gender separately.
The older infants obtained the better outcomes in BSID-II. The correlation between the first and second assessments for the Psychomotor Developmental Index (PDI) was r = 0.30, for the Mental Developmental Index (MDI) was r = 0.33, and between the second and third assessments the correlation for the PDI was r = 0.40, for the MDI was r = 0.59. That results suggest a low or moderate degree of relationship between the tests outcomes. Only 8,8% to 34,8% of variance in the infants later BSID-II scores could be explained by their earlier scores. The correlation between the tests scores was higher between outcomes obtained by girls than boys.
The BSID-II should not be treated as a useful measure for predictive purposes of infants development.
尽管贝利婴儿发展量表第二版（BSID-II）在临床和研究环境中都被广泛使用，但只有少数已发表的研究考察了其随时间的稳定性。
本研究的目的是考察在生命的头三年中，BSID-II心理和运动得分的稳定性。
本研究纳入的所有儿童是一项关于胎儿和儿童对环境因素易感性研究中的随访样本。在波兰克拉科夫进行产前招募的队列包括408名儿童。在婴儿12个月末、24个月末和36个月末对其进行BSID-II的心理和运动量表测试。使用为整个婴儿组以及分别为每个性别计算的皮尔逊相关系数，评估从第一次到第二次和第三次评估的测试分数的稳定性。
年龄较大的婴儿在BSID-II中取得了更好的成绩。心理运动发展指数（PDI）第一次和第二次评估之间的相关性为r = 0.30，心理发展指数（MDI）为r = 0.33，第二次和第三次评估之间，PDI的相关性为r = 0.40，MDI为r = 0.59。这些结果表明测试结果之间的关系程度较低或中等。婴儿后期BSID-II分数中只有8.8%至34.8%的方差可以由其早期分数解释。女孩获得的测试分数之间的相关性高于男孩。
BSID-II不应被视为预测婴儿发育的有用指标。
