The World Health Organization in its Quality of Life study group has defined it as "an individual's perception of their life situation, in the context of their culture and value systems, in relation to their objectives, expectations, standards and concerns." It is a broad concept that has been operationalized in areas or domains: physical health, psychological state, level of independence, social relationships, personal beliefs and their relationship with the most salient characteristics of the environment.

It is in this sense that the operationalization of the Quality of Life concept has led to such formulation and construction of instruments or surveys that assess people's satisfaction, from a general perspective. However, the particularities of the different pathological processes and the pressure to objectify their specific impact have motivated the creation of specific instruments related to each disease and its particular impact on people's lives. In this way, we can distinguish general quality of life instruments and others related to specific aspects of the different pathological conditions (quality of life instruments related to the disease). The basic factors are the family, education, work, infrastructure, and health of each person.
