Abstract
Background: The WHOQOL-BREF is a generic questionnaire to measure quality
of life created by the Study Group on Quality of Life of the World Health Organization. Aim: To adapt and evaluate the psychometric properties of the Spanish version
of the WHOQOL-BREF instrument in a group of Chilean older subjects living in
Metropolitan Santiago. Material and Methods: A linguistic-cultural adaptation
of the Spanish version of the WHOQOL-BREF was performed and tested in a pilot
study. Subsequently, the modified scale was applied to a group of 1186 older women
aged 72 ± 8 years and 334 men aged 72 ± 7 years. The psychometric properties such
as internal consistency, item-total correlation of responses, and construct validity
were evaluated. A confirmatory factor analysis was done to check if the dimensions
described in the original version, were evaluated. Analyses were performed with STATA statistical software 10.0 and LISREL 8.50. Results: Confirmatory factor analysis
confirmed that the dimensions physical health, psychological, social relationships and
environment, described by the authors in their original description, were maintained.
The instrument had a good internal consistency with a Cronbach alpha of 0.88 for
the total scale and ranging from 0.70 to 0.79 in each of the dimensions. Conclusions: The evaluated version of the WHOQOL-BREF has an acceptable reliability
and validity, and suggests that it is suitable for the assessment of Quality of Life in
elderly people in Chile.
