Comparative Study
Content comparison of health-related quality of life (HRQOL) instruments based on the international classification of functioning, disability and health (ICF).
The increasing recognition of the patient perspective and, more specifically, functioning and health, has led to an impressive effort in research to develop concepts and instruments to measure them. Health-Related Quality of Life (HRQOL) and the International Classification of Functioning Disability and Health (ICF) represent two different perspectives from which to look at functioning and health. Therefore, it is expected that both will often be used concurrently in clinical practice, research and health reporting. ⋯ Only four of the six instruments address environmental factors. The ICF proved highly useful for the comparison of HRQOL instruments. The comparison of selected HRQOL instruments may provide clinicians and researchers with new insights when selecting health-status measures for clinical studies.
