Construcción de una escala de depresión con el modelo de Rasch

Abstract

El objetivo de este trabajo es evaluar las propiedades psicom?tricas de un cuestionario compuesto pordiferentes indicadores de depresi?n en poblaci?n joven espa?ola con el objetivo de mejorar su calidadt?cnica. Participaron 310 sujetos de entre 18 y 24 a?os, con estudios de nivel b?sico, medio y superior.Los datos se analizaron con el modelo de Rasch. Se ha encontrado que el ajuste medio de los ?tems almodelo es alto, y que tambi?n lo es la fiabilidad promedio de las estimaciones de los ?tems (.97) y delas personas (.88). Tras eliminar los cuatro ?tems que desajustan y los doce que muestran DIF asociadoal sexo, la escala resultante permite una medici?n objetiva de la depresi?n. Con esta ?ltima escalase encuentran las previstas diferencias asociadas al sexo.

This study examines the psychometric propertiesof a depression questionnaire. The goal was to improve the technical quality of traditional measuresof depression in Spanish youth. 310 participants, aged 18-24 years, filled in the self-report questionnaire.The data were analysed by means of the Rasch model. Results show that model fit, averageitem reliability (.97), and average person reliability (.88) are high. After deleting four indicators showingmisfit and 12 showing sex bias, the resulting scale measures clinical depression objectively.Using this scale, the expected sex-related differences are found.
