Validación de la escala de estrés percibido (EEP-13) en una muestra de funcionarios públicos venezolanos. / The perceived stress scale (PSS-13) validation in a sample of venezuelan public workers

Abstract

Resumen En una muestra venezolana de 867 policias y bomberos del estado Merida, se valido la escala de estres percibido (EEP) elaborada por Cohen, Kamarak y Mermelstein (1983) y adaptada al espanol en Mexico por Landero y Gonzalez (2004). La aplicacion se realizo en conjunto con otros instrumentos y con el consentimiento previo de los participantes. A traves de un analisis factorial exploratorio se extrajeron dos dimensiones, las cuales coincidieron con las reportadas en estudios previos. Mediante analisis factorial confirmatorio se excluyo el item 12, resultando la escala EEP definitiva con 13 items. Mostro excelentes indices de ajuste y un alfa de Cronbach de 0,95. Se presentan tambien pruebas de validez convergente y divergente.

The final version is a 13-items scale. Resulting in the EEP-13. Also, it shows excellent rates of adjustment and a Cronbach alpha of 0.95. Evidence of convergent and divergent validity is presented.
