The Neonatal Behavioral Assessment Scale (NBAS, Brazelton & Nugent, 1995) is an instrument conceived to observe the neonatal neurobehavior. Data analysis is usually performed by organizing items into groups. The most widely used data reduction for the NBAS was developed by Lester, Als, and Brazelton (1982).
Examine the psychometric properties of the NBAS items in a sample of 213 Portuguese infants.
The NBAS was performed in the first week of infant life (3 days±2) and in the seventh week of life (52 days±5).
Principal component analyses yielded a solution of four components explaining 55.13% of total variance. Construct validity was supported by better neurobehavioral performance of 7-week-old infants compared with 1-week-old infants.
Changes in the NBAS structure for the Portuguese sample are suggested compared to Lester factors in order to reach better internal consistency of the scale.
新生儿行为评估量表（NBAS，Brazelton & Nugent，1995）是一种用于观察新生儿神经行为的工具。数据分析通常通过将项目组织成组来进行。最广泛使用的 NBAS 数据缩减方法是由 Lester、Als 和 Brazelton（1982）开发的。
在 213 名葡萄牙婴儿的样本中检查 NBAS 项目的心理测量特性。
在婴儿生命的第一周（出生后 3 天±2 天）和第七周（52 天±5 天）进行 NBAS。
主成分分析得出了一个由四个组成部分组成的解决方案，解释了总方差的 55.13%。与 1 周龄婴儿相比，7 周龄婴儿的神经行为表现更好，支持了结构有效性。
与 Lester 因素相比，建议对葡萄牙样本的 NBAS 结构进行更改，以达到更好的量表内部一致性。
