A structured review of quality of life instruments for head and neck cancer patients.
BACKGROUND
Quality of life (QOL) is an important treatment outcome for head and neck cancer. Our purpose was to critically review published disease-specific QOL instruments.


METHODS
Medline and Cancerlit were searched from 1966-1999. Eight disease-specific QOL instruments were identified, described, and appraised for development, sensibility, reliability, validity and responsiveness to change.


RESULTS
Several of the available instruments have been well-developed and characterized. No one instrument is ideal for all purposes. When selecting a disease-specific QOL instrument for head and neck cancer patients, careful consideration must be given to disease subsite, treatment, timing of assessment, clinical setting, study purpose and research question.


CONCLUSIONS
Validation of QOL instruments is an ongoing process. Direct comparisons of different instruments may help to establish the most appropriate questionnaire for each situation. Efforts should be focused on the evaluation of existing instruments, rather than the development of new questionnaires.
