The purpose of this study was to determine the effectiveness of the Bayley Scales of Infant Development, Third Edition (Bayley-III) to track development and classify delays in low- and high-risk infants across the first two years of life. We assessed cognitive, language, and motor development in 24 low-risk full-term and 30 high-risk preterm infants via seven assessments performed between 3 and 24 months corrected age. The Bayley-III resulted in highly unstable delay classifications, low sensitivities, and poor positive predictive values across time. The results highlight that early intervention professionals, researchers, and policy makers should: (1) emphasize clinical opinion and prevalence of risk factors rather than standardized assessment findings when classifying delays and determining eligibility for services, and (2) develop more effective developmental assessments for infants and young children.
本研究旨在确定贝利婴幼儿发展量表第三版（Bayley-III）在追踪低危和高危婴儿生命最初两年发育情况和分类发育迟缓方面的有效性。我们通过在矫正年龄 3 至 24 个月之间进行的 7 次评估，评估了 24 名低危足月婴儿和 30 名高危早产儿的认知、语言和运动发育情况。Bayley-III 导致发育迟缓分类高度不稳定，敏感性低，阳性预测值随时间变化而降低。研究结果表明，早期干预专业人员、研究人员和政策制定者应该：（1）在分类发育迟缓并确定服务资格时，应强调临床意见和风险因素的普遍性，而不是标准化评估结果；（2）为婴儿和幼儿开发更有效的发育评估方法。
