Resumen


Objetivo: Evaluar las evidencias de validez de una aproximación unidimensional al WHOQOL-BREF en adultos mayores. Método: Se aplicó el instrumento a una muestra probabilística de 510 adultos mayores de Bucaramanga y Manizales adscritos a centros día o centros vida. Se realizaron análisis Rasch de ajuste de categorías de respuesta, ajuste de los ítems y de las personas, funcionamiento diferencial de los ítems, unidimensionalidad y confiabilidad. Resultados: Fue necesario colapsar las categorías de respuesta de cinco a cuatro opciones. Todos los ítems ajustaron adecuadamente al modelo de Rasch, al igual que una alta proporción de adultos mayores. Se identificó funcionamiento diferencial tipo C en cinco ítems aunque se pudo establecer que este tiene un bajo impacto en la medida. La consistencia interna fue de 0.92 y la confiabilidad de los ítems de 0.98. Se presenta el mapa de Wright. Conclusiones: A partir del WHOQOL-BREF se puede obtener una medida unidimensional a nivel de intervalo de calidad de vida en adultos mayores.
