Abstract

Two studies evaluated the psychometric properties and the latent structure of the Portuguese version of the Penn State Worry Questionnaire (PSWQ) in a large Brazilian college student sample. Results indicated that PSWQ had an adequate internal consistency. Exploratory factor analyses yielded a two-factor solution. One factor was related to the worry presence and incorporated all the non-reversed items. The other factor was associated to worry absence and incorporated all the reversed items. Confirmatory factor analysis leaded to a three-factor solution. One factor included all the PSWQ items whereas the two other factors were linked to the reversed and non-reversed worded items. Correlations coefficients of these two reversed and non-reversed factors with the total scores of the PSWQ and the trait form of the State-Trait Anxiety Inventory suggest that PSWQ has a single meaningful construct.

Dos estudios evaluaron las propiedades psicométricas y la estructura latente de la versión portuguesa del Penn Worry State Questionnaire (PSWQ) en una muestra de gran tamaño de estudiantes universitarios de Brasil. Los resultados indicaron que el PSWQ tenía una adecuada consistencia interna. Un análisis factorial exploratorio ofreció una solución de dos factores. Un factor estaba relacionado con la presencia de preocupación e incluía todos los ítems no invertidos. El otro factor estaba asociado a la ausencia de preocupación e incluía todos los ítems invertidos. Un análisis factorial confirmatorio condujo a una solución de tres factores. Un factor incluía todos los elementos del PSWQ mientras que los otros dos factores estaban relacionados con los ítems redactados de forma directa e inversa. Los coeficientes de correlación de estos dos factores (de los ítems invertidos y no invertidos) con las puntuaciones totales del PSWQ y la versión rasgo del Inventario de Ansiedad Estado-Rasgo (STAI) sugieren que un único constructo subyace a la estructura del PSWQ.
