To determine whether item groupings derived from the Bayley Infant Neurodevelopmental Screener (BINS) are stable and predictive of 36-month cognitive and motor outcome.
BINS was administered at 6, 12, and 24 months, and the Bayley-II or McCarthy scales at 36 months. The BINS was factor analyzed, and factors, biomedical and environmental variables, were related to 36-month outcomes.
Three factors were identified at each age, accounting for 52% to 64% of the variance. Continuity in factors over infancy and predictive utility of similar functions at 36 months were found. Optimal factor scores (> or = 75th percentile) increased the likelihood of later normal cognitive or motor outcome (ORs 2.14-7.94).
Stability and continuity over time exist in specific subdomains of function on a neurodevelopmental screening test.
确定源自贝利婴儿神经发育筛查量表（BINS）的项目分组是否稳定，以及是否能预测36个月时的认知和运动结果。
在6个月、12个月和24个月时进行BINS测试，并在36个月时进行贝利-II或麦卡锡量表测试。对BINS进行因素分析，并将因素、生物医学和环境变量与36个月时的结果相关联。
在每个年龄阶段均识别出三个因素，这些因素解释了52%至64%的方差。发现婴儿期各因素具有连续性，且类似功能在36个月时具有预测效用。最佳因素得分（≥第75百分位数）增加了后期认知或运动结果正常的可能性（比值比为2.14 - 7.94）。
神经发育筛查测试中特定功能子领域随时间存在稳定性和连续性。
