WHOQOL-BREF: quality-of-life assessment

What this assessment is

The WHOQOL-BREF is a 26-item self-report measure of quality of life.

It asks about the person's own experience of physical health, psychological health, social relationships, and environment. The result is a four-part profile, not one overall score.

The measure also includes two general ratings. One concerns overall quality of life, and the other concerns general satisfaction with health. These ratings remain separate from the four domains.

Keep them separate.

The WHOQOL-BREF is not a symptom checklist. It asks how life is going from the respondent's point of view.

Perspective is central.

It cannot diagnose a health condition.

Who it was designed for

The World Health Organization developed the WHOQOL instruments for international use. Quality of life is treated as a personal judgment shaped by culture, values, goals, expectations, and circumstances.

The shorter WHOQOL-BREF was derived from the 100-item WHOQOL assessment. The original development study tested data collected across many countries and supported the four-domain structure.

The generic adult form has been used in community, medical, mental health, and research settings. A validated local-language version should be used when one is available.

Language and culture matter. A score from one country should not be interpreted with norms from another country unless there is evidence that the comparison is suitable.

Culture changes context.

The person usually answers for themselves. A proxy report is a different perspective and should be labeled as such.

How it is administered

The respondent answers 26 questions about the previous two weeks.

Most people can complete the form in several minutes. Reading ability, illness, fatigue, and the need for an interview can change the time required.

Use the complete validated form and its instructions. Do not combine questions from the WHOQOL-100 with the WHOQOL-BREF or change the recall period between assessments.

The same language version and administration method should be used when tracking change over time.

What it measures

The WHOQOL-BREF produces four domain scores:

• physical health
• psychological health
• social relationships
• environment

Physical health covers experiences such as energy, pain, sleep, mobility, daily activities, and capacity for work.

Psychological health covers feelings, thinking, self-esteem, body image, personal beliefs, and the balance of positive and negative experience.

Social relationships cover personal relationships, social support, and intimate life.

Environment covers safety, home conditions, finances, access to information and services, leisure, transport, and the physical setting.

The domains can move in different directions. Someone may report strong social relationships while having poor physical health. That difference is useful and should not be hidden inside a total.

Domains can diverge.

How scoring works

Some responses are reversed so that higher values consistently indicate better quality of life.

Calculate a mean for each of the four domains. The standard method multiplies each domain mean by four, giving domain scores from 4 to 20.

Domain scores can also be transformed to a 0-to-100 scale. The transformation changes the scale, not the person's answers. Always state whether a result uses the 4-to-20 or 0-to-100 format.

Scale must match.

Do not add all 26 responses into one total. The standard WHOQOL-BREF produces four domain scores and two separate general ratings.

Use four scores.

Missing responses require care. The official WHO guide sets limits for when a domain mean can be estimated and when a form should not be scored. Do not invent a local prorating rule.

How to interpret WHOQOL-BREF scores

A higher domain score indicates better reported quality of life in that area during the previous two weeks.

Read all four domains. A single domain may show the main difficulty or the strongest part of the person's life.

There are no universal low, moderate, or high bands that apply across countries, diagnoses, and settings. If a service uses a cutoff or percentile, it should identify the population and purpose from which it came.

For repeated assessment, compare like with like. Keep the language, respondent, recall period, scoring scale, and administration method consistent.

A change may reflect health, treatment, relationships, housing, money, safety, support, or expectations. The score shows the person's report. It does not identify the cause.

It is descriptive.

What the scores cannot tell you

The WHOQOL-BREF cannot diagnose depression, disability, physical illness, or any other condition.

It cannot show which treatment a person needs. It also cannot decide whether a living situation is safe or whether someone qualifies for a service or benefit.

A low score is not evidence that every part of life is poor. A high score does not rule out a serious problem that the broad domains fail to capture.

The measure does not replace a clinical history or a direct conversation about what matters to the person.

Evidence and limitations

The WHOQOL-BREF was built from international WHOQOL data. A later field trial across 23 countries found acceptable performance across many cultures and health settings.

That breadth is a strength, but it does not make every comparison valid. Translations, cultural expectations, age, illness, and local conditions can affect how people use the response scale.

The short form reduces burden but gives less detail than the WHOQOL-100. Its three-item social-relationships domain can also be less stable than the longer domains in some samples.

Self-report is central to the measure. The result captures the person's judgment, which may differ from a clinician's or family member's view.

Use the profile to open a specific conversation. Ask which domain changed, what influenced it, and what improvement would mean to the person.

Ask what changed.
