En este trabajo se analizan las puntuaciones obtenidas por una muestra de 220 neonatos sanos, nacidos a término, evaluados con la Escala para la evaluación del comportamiento neonatal, 3ª edición. Se han obtenido puntuaciones típicas para cada uno de los 35 ítems conductuales y se ha realizado un análisis de componentes principales de las agrupaciones de ítems. Los factores obtenidos (muy similares a los de la escala original) son los cinco siguientes: Sistema nervioso autónomo-motor; Habituación; Organización del estado; Regulación del estado y Social interactivo. El análisis de la fiabilidad de estos factores (la media de los coeficientes alfa de Cronbach con ítems tipificados es 0,78) indica que la consistencia interna de las puntuaciones es entre moderada y alta.

Psychometric evaluation of the Brazelton Scale in a sample of Spanish newborns. This study analyses the data obtained from a sample of 220 healthy full-term neonates evaluated with the Neonatal Behavioral Assessment Scale, NBAS, 3rd edition. Standard scores were obtained for each of the 35 behavioral items and analysis of the main components of all the clusters was performed. Similarly to the original scale, the five following factors were obtained: Autonomic and Motor Systems, Habituation, State Organization, State Regulation, and Social Interactive. The analysis of the reliability of these groupings reveals that it is between moderate and high (the average Cronbachs alpha coefficient was .78).
