This article aims to describe the processes of conceptual and methodological development used for the creation of the Ferrans and Powers Quality of Life Index (QLI), and to make available the current generic version adapted to the Portuguese language, expecting to enlarge its application in different contexts and samples of the Brazilian population. QLI is an instrument designed to evaluate quality of life based on the levels of satisfaction and importance in four dimensions: Health/functioning, Psychological/spiritual, Socioeconomic and Family. Previous studies have showed that the QLI Brazilian Portuguese version may be used as a valid and reliable measure of quality of life.
