What type of data does quality-of-life (QOL) data assess?

Quality-of-life (QOL) data is designed to provide a comprehensive assessment of an individual's overall well-being, which includes both physical and mental health dimensions. This type of data encompasses various aspects of life that contribute to a person's quality of existence, such as emotional status, social functioning, and physical health. It goes beyond just measuring symptoms or demographic details by taking into account the subjective experiences of individuals regarding their health and how it affects their daily lives.

By focusing on overall well-being, QOL data helps researchers and clinicians understand the impact of medical conditions and treatments on patients, enabling a more holistic approach to patient care and the evaluation of treatment efficacy.
