Quality of Life Index (QLI)
The Quality of Life Index (QLI), Copyright 1984 and 1998 (USA) by Carol Estwing Ferrans and Marjorie Powers, was developed to measure quality of life, defined as “a person’s sense of well-being that stems from satisfaction or dissatisfaction with the areas of life that are important to him/her”(1). The QLI measures importance of, and satisfaction with, different aspects of life.
It has been developed into many alternate versions such as an Arthritis Version and a Cancer Version, and has been translated into many languages. The generic version includes 33 items, using a 6-point likert-type scale, for each section (66 items total). Approximately 10 minutes is required for completion.
