Resumen

Antecedentes/Objetivo: El Padua Inventory-Revised (PI-R) es un instrumento ampliamente utilizado para medir los síntomas obsesivo-compulsivos en muestras clínicas y no clínicas. Llevamos a cabo un meta-análisis de generalización de la fiabilidad del PI-R. Método: Una búsqueda exhaustiva de la literatura arrojó 118 estudios empíricos que habían aplicado el PI-R, de los cuales 30 estudios (33 muestras) reportaron una estimación propia de la fiabilidad. Resultados: Asumiendo un modelo de efectos aleatorios, la fiabilidad en términos de consistencia interna promedio (alfa de Cronbach) fue de 0,92 (IC del 95% [0,91, 0,93]) para las puntuaciones totales, y osciló entre 0,74 y 0,89 para las subescalas. Asumiendo modelos de efectos mixtos, los análisis de moderadores mostraron una relación positiva estadísticamente significativa entre la desviación típica de las puntuaciones totales y los coeficientes de fiabilidad (p = 0,002; R2 = 0,38). Conclusiones: En términos de fiabilidad, se encontró que el PI-R es adecuado tanto para fines clínicos como de investigación, aunque con una alta heterogeneidad entre los estudios. Es necesario que los estudios empíricos futuros que apliquen el PI-R proporcionen al menos una estimación de la fiabilidad basada en sus propios datos.
