Evaluación de la confiabilidad y validez de constructo de la Escala de Calidad de Vida en Salud SF-12 en población chilena (ENCAVI 2015-6)
Background: Health-Related Quality of Life (HRQoL) is understood as a multidimensional variable, mostly measured using the SF-12 questionnaire. However, this measurement doesn't always replicate the factorial structure theoretically expected, hindering potential conclusions. Aim: To assess th...
