Abstract
El Penn State Worry Questionnaire (PSWQ) es la medida prin-
cipal de la preocupación inespecífica que caracteriza al trastorno de ansie-
dad generalizada (TAG). Este estudio explora la validez del PSWQ en Co-
lombia y su invarianza de medida entre género y participantes clínicos y no
clínicos. Se utilizó la versión abreviada de 11 ítems del PSWQ propuesta
por Sandín, Chorot, Valiente y Lostao (2009) porque los ítems redactados
negativamente han mostrado ser problemáticos para los hispanohablantes.
Adicionalmente, la investigación ha sugerido que los ítems redactados en
negativa carecen de utilidad práctica. El PSWQ-11 se administró a un total
de 1045 participantes, incluyendo una muestra de participantes no clínicos
(N = 710) y una muestra de participantes clínicos (N = 335). La consisten-
cia interna del PSWQ-11 a través de muestras fue excelente. El modelo de
un factor mostró un ajuste aceptable a los datos. Se observó invarianza mé-
trica y escalar a través de género y muestras clínicas y no clínicas. En con-
clusión, el PSWQ-11 parece ser una medida válida de la preocupación tipo
TAG, mientras que los datos sobre equivalencia factorial permiten la com-
paración de puntuaciones a través de género y participantes clínicos y no
clínicos.
The Penn State Worry Questionnaire (PSWQ) is the gold stand- ard measure of the unspecific worry that characterizes generalized anxiety disorder. This study aims to explore the validity of the PSWQ in Colombia and its measurement invariance across gender and clinical and nonclinical participants. An abbreviated, 11-item version of the PSWQ by Sandín, Chorot, Valiente, and Lostao (2009) was used because the negatively word- ed items have shown to be problematic for Spanish speakers. Additionally, research has suggested that the negatively worded items of the PSWQ lack of practical utility. The PSWQ-11 was administered to a total of 1045 par- ticipants, including a sample of nonclinical participants (N = 710) and a sample of clinical participants (N = 335). The internal consistency of the PSWQ-11 across samples was excellent. The one-factor model showed an acceptable fit to the data. Metric and scalar invariance were observed across gender and clinical and nonclinical samples. In conclusion, the PSWQ-11 seems to be a valid measure of GAD-related worry in Colombia, whereas data on factorial equivalence data warrant the comparison of scores across gender and clinical and nonclinical sample
