Escala de qualidade de vida: Análise estrutural de uma versão para idosas

Abstract

This study sought to analyze the structure of the young adult version of the Quality of Life Scale - QOLS, proposed by Soares in a sample of elderly women, considering more robust psychometric properties. To achieve this Confirmatory Factor Analysis (CFA) and Structural Equation Modeling (SEM) were conducted using AMOS GRAFICS (version 18.0). The sample was comprised of 143 women aged 67.45 ± 3.87 years, from the Elderly Center at a private University in Brasilia, Federal District. Two models were assessed, namely one-factor and two-factor models. The results suggest that the best items to the Quality of Life Scale were found in the two-factor model (psychological and behavioral) presenting, specifically, the following items of quality adjustment: χ2/gl ratio = 1.05, GFI = 0.89, AGFI = 0.85, CFI = 0.99, RMSEA (90%IC) = 0.02, CAIC = 632.85 e ECVI = 2.56. It was concluded that the scale presents psychometric properties able to ensure internal structure and consistency in a sample of elderly women.
