Resumen


En este estudio se presenta la adaptación y validación del Rand-36 Ítem Health Survey 1.0 (RAND-26) en mujeres, entre 18 y 65 años, de Buenos Aires. En relación con la validez de constructo, se realizó un análisis factorial exploratorio mediante un análisis de componentes principales con rotación ortogonal utilizando el método varimax. Se halló que, la solución de dos factores (físico y mental) resultó ser la más parsimoniosa y apropiada teóricamente. El ? de Cronbach fue excelente para la escala total (? = .911) y muy bueno para ambos componentes (componente físico: ? = .873 y componente mental: ? = .881). Asimismo, se observaron indicadores de validez concurrente. En conclusión, la versión local del instrumento presentó indicadores adecuados de validez y consistencia interna, resultando promisorio para la evaluación de la calidad de vida percibida relacionada con la salud.

Health-related quality of life: exploratory factor analysis of RAND-26 in a non-probabilistic female sample from Buenos Aires. This study presents the adaptation and validation of the Rand-36 Item Health Survey 1.0 (RAND-26) in women aged between 18 and 65 from Buenos Aires. Regarding construct validity, an exploratory factor analysis was developed. A principal component analysis with orthogonal rotation solution (varimax) was performed. A two-factor structure (physical and mental) was the most parsimonious and theoretically appropriate. The Cronbach´s Alpha was excellent for the full-scale (? = .911) and very good for both components (physical component: ? = .873 and mental component: ? = .881). Concurrent validity indicators were also found. In conclusion, this local version of the instrument shows appropriate indicators of validity and internal consistency. It is a valid measure of health-related and perceived quality of life.
