Abstract
Este trabajo analizó las propiedades psicométricas en una muestra de 590 estudiantes universitarios españoles de una versión española del Inventario de Ansiedad de Beck (BAI). La fiabilidad de consistencia interna fue alta (α = 0,88) y los análisis factoriales revelaron una dimensión de ansiedad general compuesta de dos factores sintomáticos altamente relacionados, uno somático y otro afectivo-cognitivo. La validez de contenido del BAI fue aceptable pues, tomando como referencia el DSM-IV, sus ítems cubren el 45% de los criterios sintomáticos específicos de los trastornos de ansiedad y el 78% de los síntomas que definen las crisis de angustia. El BAI correlacionó 0,58 con el Inventario para la Depresión de Beck-II, pero los análisis factoriales revelaron que sus ítems forman dos factores distintos, sugiriendo que la correlación entre ambos se debe más a la relación entre los constructos de ansiedad y depresión que a un problema de validez discriminante. Los análisis de validez de criterio respecto a la entrevista estructurada Quick DIS-III-R indicaron que el BAI tiene buena capacidad discriminadora para detectar casos de ansiedad patológica en muestras de estudiantes universitarios. Finalmente, se ofrecen datos normativos a partir de la muestra total y de la muestra dividida por sexos, ya que las mujeres puntuaron más alto que los varones.
The present study examined the psychometric properties of a Spanish version of the Beck Anxiety Inventory (BAI) in a sample of 590 Spanish university students. The BAI demonstrated a high level of internal consistency (α= 0,88), and the factor analyses revealed a general anxiety dimension composed of two highly interrelated factors, corresponding to somatic and affective- cognitive symptoms. Taking the DSM-IV as standard the content validity of the BAI was adequate since, its items covered 45% of the specific symptomatic criteria of anxiety disorders and 78% of the symptoms of panic attacks. The BAI was correlated 0,58 with the Beck Depression Inventory-II, but a combined factor analysis of their items revealed two distinct factors, suggesting that the correlation between the BAI and BAI-II is a reflection of the relationship between anxiety and depression constructs rather than a problem of discriminant validity. Criterion validity analyses concerning the Quick DIS-III-R structured interview pointed out that the BAI had a good discriminative ability to identify clinical anxiety in university student samples. Finally, norms scores for university students were provided from the total sample and from the male and female subsamples, since females scored higher than males.
