Estructura Factorial de la Escala de Trastorno por Estrés Agudo en población mexicana.
Barra lateral del artículo
Contenido principal del artículo
Resumen
cuatro semanas posteriores al trauma. Existen distintas limitaciones en la definición del constructo y su evaluación. El propósito
del estudio fue validar la Escala de Trastorno por Estrés Agudo en población mexicana mediante análisis factoriales. Se contó con
204 participantes de entre 18 y 59 años de edad. El análisis factorial exploratorio arrojó tres factores donde se agrupan: síntomas de
reexperimentación y activación, síntomas de evitación y síntomas disociativos, con una varianza explicada acumulada de 67.90%,
así como un Alpha de Cronbach .96 para la escala global, y .94, .91 y .89 para cada factor; por último, el análisis factorial confirmatorio
muestra un ajuste adecuado del modelo. Se concluye que la escala es válida y confiable en población mexicana, donde se
sugiere realizar análisis factoriales en distintas poblaciones para una mayor definición. © 2017 Universidad Nacional Autónoma de
