目的：评估贝利婴幼儿发展量表第三版（Bayley - III）检测极早产和足月出生的2岁儿童发育迟缓的能力。
设计：前瞻性队列研究。
地点：澳大利亚维多利亚州。
参与者：研究对象为2005年在澳大利亚维多利亚州出生的孕周小于28周（极早产）或出生体重小于1000克（极低出生体重；n = 221）的连续存活儿童，以及随机选取的足月且出生体重正常的对照组儿童（n = 220）。
主要观察指标：由对分组情况不知情的心理学家在儿童2岁时（早产儿童已根据早产情况进行校正）使用新的Bayley - III量表进行评估。
结果：两个队列的随访率都很高（>92%）。极早产/极低出生体重组所有综合和分项测试得分的平均值显著低于对照组（P <.001），所有组间差异的幅度超过三分之二标准差。极早产/极低出生体重组的平均值接近标准均值，但相比之下，对照组的平均值高于预期，综合得分比标准均值高0.55至1.23标准差。使用参考值会严重低估发育迟缓儿童的比例，但相对于对照组的均值（标准差）计算时则在预期范围内。
结论：Bayley - III量表严重低估了澳大利亚2岁儿童的发育迟缓情况。《儿科学与青少年医学档案》2010年；164(4):352 - 356
Objective: To assess the ability of the third edition of the Bayley Scales of Infant and Toddler Development (Bayley-III) to detect developmental delay in 2-year-old children who were extremely preterm and those carried to term.Design: Prospective cohort study.Setting: The state of Victoria, Australia.Participants: Subjects were consecutive surviving children who were born either at less than 28 weeks' gestational age ( extremely preterm) or with less than 1000 g birth weight ( extremely low-birth-weight; n = 221) in the state of Victoria, Australia, in 2005 and randomly selected controls who were both carried to term and of normal birth weight (n = 220).Main Outcome Measure: Children were assessed by psychologists blinded to knowledge of group at 2 years of age, corrected for prematurity with the new Bayley-III scale.Results: Follow-up rates of both cohorts were high (>92%). Mean values for all composite and subtest scores for the extremely preterm/extremely low-birth-weight group were significantly below those of the control group (P < .001), with the magnitude of all group differences being in excess of two-thirds SD. Mean values for the extremely preterm/extremely low-birth-weight group approached the normative mean, but in contrast, the mean values for the control group were higher than expected, with composite scores being between 0.55 and 1.23 SD above the normative mean. Proportions of children with developmental delay were grossly underestimated using the reference values, but were within the expected range when computed relative to the mean ( standard deviation) for the controls.Conclusion: The Bayley-III scale seriously underestimates developmental delay in 2-year-old Australian children.
