Objective[edit | edit source]
To measure the quality of life of individuals and populations.
The WHOQOL-100 was developed alongside its shorter counterpart, the WHOQOL-BREF, by the World Health Organisation (WHO) and published in 1995. It was developed over several years and from 15 centres around the world. The questions stem from multiple statements about quality of life, health and well-being from people with and without disease, and health professionals. It has been tested for reliability and vailidity.
Intended Population[edit | edit source]
Specific populations or groups with a particular disease, or general populations.
Method of Use[edit | edit source]
The WHOQOL-100 is patient-reported questionnaire. It comprises 100 questions on the individual's perceptions of their health and well-being over the previous two weeks. Responses to questions are on a 1-5 Likert scale where 1 represents "disagree" or "not at all" and 5 represents "completely agree" or "extremely".
The questions cover six domains of quality of life plus general QOL and health:
- Overall Quality of Life and General Health
- Physical Health
- Energy and fatigue
- Pain and discomfort
- Sleep and rest
- Bodily image and appearance
- Negative feelings
- Positive feelings
- Thinking, learning, memory and concentration
4. Level of Independence
- Activities of daily living
- Dependence on medicinal substances and medical aids
- Work capacity
5. Social Relations
- Personal relationships
- Social support
- Sexual activity
- Financial resources
- Freedom, physical safety and security
- Health and social care: accessibility and quality

7. Spirituality/Religion/Personal beliefs
- Religion/Spirituality/Personal beliefs (single facet)

Evidence[edit | edit source]
In its extensive development, the WHOQOL group has rigorously tested the WHOQOL-100's psychometric properties. Multiple studies have also tested the WHOQOL-100's psychometric properties in various disease groups. Some examples follow.
Reliability[edit | edit source]
The WHOQOL-100 demonstrated strong reliability when measuring QOL in people with depression (Cronbach's alpha = 0.96), schizophrenia (Cronbach's alpha = 0.94), people with breast cancer, and when comparing sick and well people.
Validity[edit | edit source]
In a study of people receiving treatment for moderate depression, the domains and facets of the WHOQOL-100 demonstrated high construct, divergent and convergent validity. The WHOQOL-100 has also demonstrated validity in comparing a general population of well and sick people, schizophrenia and chronic pain.
Responsiveness[edit | edit source]
Miscellaneous[edit | edit source]
The WHOQOL-100 is available in more than 20 languages. It shows good discriminatory power in people with depression i.e. those with worse depression record lower scores.
