Description

Background:
The World Health Organization Quality of Life (WHOQOL) project was initiated in 1991. WHOQOL-BREF was developed from the WHOQOL-100 at the same time as the WHOQOL-100. The WHOQOL BREF consists of 26 items, which measure the following broad domains: physical health, psychological health, social relationships, and environments. This version has been translated into approximately 19 different languages.

The WHOQOL-100 consists of 24 facets also grouped into four domains related to quality of life (Physical Health, Psychological, Social Relationships, and Environment) as well as one facet on overall quality of life and general health. One item from each facet, which best explains a large portion of the variance, was selected for inclusion in the WHOQOL-BREF. Two items were selected from the overall quality of life facet for a total of 26 items. In addition to data from the original 15 field centers used for development of the WHOQOL-100, five additional centers were also included.

.Developers:
The WHOQOL BREF instruments have been developed collaboratively in centers across the world under the umbrella of the WHO.

Reliability:
Reliablity was good for each of the four domains (Cronbach alpha 0.66 to 0.84). Domain scores calculated using the WHOQOL-BREF were very similar to scores calculated from the WHOQOL-100 with correlations between the two measures of 0.89 to 0.95. The WHOQOL-BREF has the same ability as the WHOQOL-100 to discriminate between healthy and sick individuals. Over a two to eight week period, test-retest reliability for the four domains was generally high (0.66 to 0.87). As with the WHOQOL-100, factor analysis confirmed the comparative fit of the 4 domain model to the global quality of life. The Physical Health domain loads most heavily on the global quality of life measure while the Social Relationships domain loads the least.
