Estructura Factorial del Inventario de Trastornos de Ansiedad Generalizada en Universitarios Mexicanos José R. Blanco Martha Ornelas Juan C. Barrón Judith M. Rodríguez-Villalobos Ingeniería Ansiedad estructura factorial validación de constructo ecuaciones estructurales El presente estudio analiza si es posible replicar los resultados psicométricos para el Inventario de Trastornos de Ansiedad Generalizada. La muestra total fue de 1307 estudiantes de las licenciaturas de Educación Física y Motricidad Humana que se ofrecen en la Universidad Autónoma de Chihuahua, con una edad media de 20.46 años. La estructura factorial del cuestionario se analizó a través de análisis factoriales confirmatorios. Los análisis, muestran que una estructura trifactorial es viable y adecuada. La estructura de tres factores (cognitiva, trastornos del sueño y síntomas somáticos), atendiendo a criterios estadísticos y sustantivos, ha mostrado adecuados indicadores de ajuste de fiabilidad y validez. Además, los resultados de los análisis factoriales llevados a cabo con las submuestras, indican la existencia de fuertes evidencias de la estabilidad de la estructura factorial. Futuras investigaciones deberían replicar estos hallazgos en muestras más amplias. 2017 artículo científico 0718-5006 https://www.redalyc.org/articulo.oa?id=373553266008 es http://www.redalyc.org/revista.oa?id=3735 Formación Universitaria application/pdf Centro de Información Tecnológica Formación Universitaria (Chile) Num.5 Vol.10
