Subjective Values of Quality of Life Dimensions in Elderly People. A SEM Preference Model Approach

This article proposes a Thurstonian model in the framework of Structural Equation Modelling (SEM) to assess preferences among quality of life dimensions for the elderly. Data were gathered by a paired comparison design in a sample comprised of 323 people aged from 65 to 94 years old. Five dimensions of quality of life were evaluated: Health, Autonomy, Family and Social Support, Social Activities and Home Conditions. An unrestricted model was estimated and subjective preference values of dimensions were obtained. According to the subjective preferences, four groups of dimensions were established: Health-Autonomy-Home and Support-Social Activities. No differences among gender and age were found in the preference values.
