Abstract
BACKGROUND: The increase in elderly population demands the need for new health measures that are reliable and valid. AIM: To compare the factor structure of the Quality of Life Scale WHOQoL-Old of the World Health Organization with the three proposed abbreviated versions of the scale. MATERIAL AND METHODS: We performed confirmatory factor analysis on data collected from 804 older people, aged 70 ± 6 years (66% females). RESULTS: One of the unifactorial models that incorporate six questions had goodness of fit values greater than 0.95 in the non-normed fit index and below .05 in the root-mean square error of approximation. CONCLUSIONS: The abbreviated version tested is a valid and reliable questionnaire to be used in Chilean older people.
