Abstract (English): The valid and reliable assessment of social anxiety is an aspect of prime relevance in the context of clinical research and diagnosis. In the present study, the psychometric properties of the short version for Spanish speakers of the Social Phobia and Anxiety Inventory (SPAI-B) were assessed using the item response theory (IRT). Although the scale is widely used in several countries with diverse social and cultural contexts, validation of the scale with the Rasch model had not yet been performed in Argentinean and Spanish populations. The results make clear that the tool allows a unidimensional validation of social anxiety with a pertinent categorization of the response scale. Furthermore, the data show that the level of severity of the items is adequate and permits detection of the clinical population. Differential functioning between gender and nationality is reported and the clinical implications of these cultural differences are discussed. [ABSTRACT FROM AUTHOR]
Abstract (Spanish): La evaluación válida y fiable de la ansiedad social es un aspecto de suma importancia práctica en contextos de investigación y diagnóstico clínico. Por ello, en el presente estudio se evaluaron las propiedades psicométricas de la versión breve para hispanohablantes del Social Phobia and Anxiety Inventory (SPAI-B) a partir de la teoría de respuesta al ítem. Si bien la escala es ampliamente utilizada en diversos países, contextos sociales y culturales, hasta ahora no se habían llevado a cabo estudios de validación de la escala desde el modelo de Rasch en población española y argentina. Los resultados evidencian que el instrumento permite una evaluación unidimensional de la ansiedad social con una categorización pertinente de la escala de respuesta. Asimismo, los datos muestran que el nivel de severidad de los ítems es adecuado y permite la detección de población clínica. Por último, se informa sobre los ítems que tienen funcionamiento diferencial entre sexo y nacionalidad, y se discuten las implicaciones clínicas de estas diferencias culturales.
