Structure and Content of the Questionnaire
The WHOQOL-BREF questionnaire is structured to assess an individual’s perception of their quality of life across various domains. It comprises a total of 26 questions, each designed to capture a specific aspect of well-being. Two questions address overall perceptions of quality of life and general health, providing a global assessment.
The remaining 24 questions are divided among four key domains: physical health, psychological health, social relationships, and environment. The physical health domain explores aspects such as pain, energy, sleep, and mobility. The psychological health domain delves into feelings, cognition, self-esteem, and body image. The social relationships domain assesses personal relationships, social support, and sexual activity. Finally, the environment domain covers aspects such as financial resources, safety, access to healthcare, and opportunities for acquiring new skills.
Each question is answered using a five-point Likert scale, allowing respondents to indicate the extent to which they agree or disagree with each statement. This structure enables a quantitative assessment of quality of life across the identified domains.
The Four Domains of Quality of Life
The WHOQOL-BREF assesses quality of life through four distinct domains, providing a comprehensive overview of an individual’s well-being. These domains are interconnected and contribute to an overall sense of life satisfaction. The first domain, Physical Health, encompasses aspects related to physical functioning, energy levels, pain, sleep, and mobility. It examines how physical well-being impacts daily activities and overall comfort.
The second domain, Psychological Health, delves into mental and emotional states, including self-esteem, body image, mood, and cognitive functions such as memory and concentration. This domain explores how psychological factors influence an individual’s perception of their life. The third domain, Social Relationships, focuses on interpersonal connections, social support, and intimate relationships. It assesses the quality and quantity of social interactions and their impact on quality of life.
Lastly, the Environment domain considers external factors that influence well-being, such as financial resources, safety, access to healthcare, opportunities for learning, and the physical environment. This domain acknowledges the role of external circumstances in shaping an individual’s overall quality of life.
Administration and Scoring of WHOQOL-BREF
Administering the WHOQOL-BREF involves presenting the questionnaire to individuals and allowing them to self-report their perceptions of quality of life. The questionnaire contains 26 questions using a 5-point Likert scale, where respondents indicate their level of agreement or satisfaction. Clear instructions should be provided to ensure accurate and reliable responses. The administrator should ensure that respondents understand the questions and feel comfortable providing honest answers.
Scoring the WHOQOL-BREF involves calculating domain scores based on the responses provided. First, raw scores are calculated for each domain by summing the scores of the relevant items. Then, these raw scores are transformed to a standardized scale ranging from 0 to 100 for easier interpretation and comparison. This transformation allows for meaningful comparisons across individuals and groups. The WHO provides detailed scoring instructions and syntax files to assist in the calculation of domain scores.
Higher scores indicate a better quality of life within that specific domain. These scores can then be used for research purposes, clinical assessments, and to evaluate the impact of interventions on quality of life.
