Quality Of Life

A recognized desirable goal in the field of developmental disabilities, about which there is a great deal of disagreement. What constitutes quality of life and how can it be measured? A number of different approaches have been taken. For example, the Quality of Life Interview Schedule (QUOLIS), designed specifically to address the needs of adults with severe and profound disabilities, involves interviews with two informants who know an individual well in different contexts, and quality of life is measured under 12 domains, such as health services and housing and safety. A second approach is reflected in the Quality of Life Project, a conceptual framework that includes three major components of quality of life, each divided into subcomponents.
