[Assessment of quality of life for laryngeal cancer patients after laryngectomy].
OBJECTIVE
This study was designed to develop a rating scale of quality of life (QOL) which fits laryngeal cancer patients after laryngectomy.


METHODS
The item pool was developed on the definition of QOL from WHO and the principles and procedures of ddveloping a rating scale. Five methods had been used in the item selection including, such as subjective evaluation methods, discrete tendency, correlation coefficient method, stepwise regression analysis, and factor analysis. The survey was conducted in 126 laryngeal cancer patients after laryngectomy in order to assess the reliability and validity of the rating scale.


RESULTS
(1) A rating scale of QOL which fits laryngeal cancer patients after laryngectomy including six domains and 27 items is was developed. (2) The split-half reliability coefficient of the scale is 0.802, and the Cronbach' α coefficient is 0.794. (3) It is inferred from the correlation analysis that there are strong correlation between items and their own domains; conversely there are weak correlation between items and other domains. Correlation coefficient is 0.731 between total score and self-rating score.


CONCLUSIONS
The reliability and validity of the rating scale is proved to work well.
