Abstract

The aim of this study was to analyse the screening utility of the Social Anxiety Screening Scale (SASS/EDAS) in a sample of 227 adolescents with social anxiety disorder and 156 without it (14-17 years). Results showed that the EDAS subscales (Avoidance, Distress and Interference) scores were reliable in terms of internal consistency (α > .80). All the subscales discriminated between adolescents with and without the disorder. They also showed a positive and significant correlation with other empirically validated measures of social anxiety. The three subscales indicated relevant sensitivity (69.16-84.14%), specificity (63.46-66.03%) and areas under the curve (.74-.81%). Binary logistic regression analyses indicated the adequate predictive utility of EDAS subscales, with the Distress subscale as the best diagnostic predictor. The data provide empirical evidence of the usefulness of EDAS as a screener for adolescent social anxiety disorder in terms of reliability, convergent and discriminant validity, diagnostic accuracy and clinical usefulness.

El objetivo de este estudio fue analizar la precisión diagnóstica y utilidad clínica de la Escala para la detección de ansiedad social (EDAS) en una muestra de 227 adolescentes con el trastorno de ansiedad social y 156 sin el trastorno (14-17 años). Los resultados muestran que las puntuaciones en las subescalas de la EDAS (Evitación, Malestar e Interferencia) fueron fiables en términos de consistencia interna (α > .80). Todas las subescalas discriminaron entre adolescentes con y sin el trastorno. También correlacionaron positiva y significativamente con otras medidas de ansiedad social validadas empíricamente. Las tres subescalas indicaron una sensibilidad (69.16-84.14%), especificidad (63.46-66.03%) y área bajo la curva (.74-.81%) adecuadas. Los análisis de regresión logística binaria determinaron la utilidad predictiva de las tres subescalas de la EDAS, si bien la subescala Malestar se mostró como el mejor predictor del diagnóstico. Los datos aportan evidencia empírica de la utilidad de la EDAS como herramienta de detección para el trastorno de ansiedad social en la adolescencia en términos de fiabilidad, validez convergente y discriminante, precisión diagnóstica y utilidad clínica.
