WHOQOL (BREF)
The short version of the World Health Organization Quality of Life Assessment (WHOQOL-BREF) is an instrument that conceptually fits with the WHO definition of QOL. Substantial effort has been put forth to properly operationalize the sub-concepts (various aspects of life) included in the instrument (WHOQOL Group 1998). The WHOQOL-BREF is grouped into 4 domains of QOL (physical health, psychological health, social relationships, and environment) and 2 items which measure overall QOL and general health.
Number of items: 24
Procedure/Administration: The instrument is a self-report questionnaire, using a 5-point Likert scale ranging from 1 (not at all) to 5 (completely). The respondents express how much they have experienced the items in the preceding 2 weeks.
How scored: All domain scores are reported between 4 and 20 (mean scores for each multiplied by 4).
Interpretability: Scores represent one’s personal experience and satisfaction regarding various aspects of life. Norms are available for different groups of people.
Acceptability: The WHOQOL is an instrument that conceptually fits with the WHO definition of QOL and substantial effort has been put forth to properly operationalize the sub-concepts (various aspects of life) included in the instrument
Languages: English
Usability: Minimal burden
Time to administer: Within a few minutes.
Time to score:N/a
Training required: None
Availability: Copies can be downloaded from the WHO website.
Equipment required: None
Summary: WHOQOL-BREF can provide data for both research and clinical purposes. Although it is a relatively brief instrument, its structure allows one to acquire specific information covering many aspects of life.
