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[1][2]. The questions stem from multiple statements about quality of life, health and well-being from people with and without disease, and health professionals[1]. It has been tested for reliability and vailidity[1].

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[1]:

  1. Overall Quality of Life and General Health
  2. Physical Health
  • Energy and fatigue
  • Pain and discomfort
  • Sleep and rest

3. Psychological

  • Bodily image and appearance
  • Negative feelings
  • Positive feelings
  • Self-esteem
  • Thinking, learning, memory and concentration

4. Level of Independence

5. Social Relations

  • Personal relationships
  • Social support
  • Sexual activity

6. Environment

  • Financial resources
  • Freedom, physical safety and security
  • Health and social care: accessibility and quality
  • Home environment
  • Opportunities for acquiring new information and skills
  • Participation in and opportunities for recreation/leisure
  • Physical environment (pollution/noise/traffic/climate)
  • Transport

7. Spirituality/Religion/Personal beliefs

  • Religion/Spirituality/Personal beliefs (single facet)

The WHO's WHOQOL-100

Evidence[edit | edit source]

In its extensive development, the WHOQOL group has rigorously tested the WHOQOL-100's psychometric properties[1]. 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)[3], schizophrenia (Cronbach's alpha = 0.94)[4], people with breast cancer[5], and when comparing sick and well people[6].

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[3]. The WHOQOL-100 has also demonstrated validity in comparing a general population of well and sick people[6], schizophrenia[4] and chronic pain[7].

Responsiveness[edit | edit source]

The WHOQOL-100 is responsive to change in QOL following liver transplant[8] and in those with chronic pain[7].

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[3].
