The World Health Organization WHOQOL-100: tests of the universality of Quality of Life in 15 different cultural groups worldwide.

The World Health Organization Quality of Life assessment (WHOQOL-100) was developed simultaneously across 15 international field centers and includes 24 facets relating to quality of life, which are grouped into 4 larger domains: physical, psychological, social relationships, and environment. It also includes 1 facet examining overall quality of life and general health perceptions. This article examines the extent to which the WHOQOL-100 assesses quality of life perceptions in different cultures and whether it is structurally comparable in these cultures. Regression analysis showed all 4 domains to be important in assessing quality of life in each of the 15 centers. Structural equation modeling suggested further support for the proposal that there are universal facets and domains that are cross-culturally important in determining quality of life and suggested that the ordering of facets within domains is comparable across cultures.
