Evaluation of the Thai, Low Vision Quality-of-Life Questionnaire (LVQOL).
BACKGROUND
Quality of life is an important measurement of medical outcome. The assessment questionnaire for low vision patients allows the services to be analysed, developed and improved.


OBJECTIVE
To evaluate the reliability and validity of the Thai version of the Low Vision Quality-of-Life Questionnaire (LVQOL).


METHODS
A cross sectional study was performed, and the content validity was examined by factor analysis and reliability assessed by the Cronbach's alpha coefficient. 47 respondents participants were interviewed at the Department of Ophthalmology, Mettapracharak Eye Center.


RESULTS
The Thai version of the LVQOL achieved good levels of validity and reliability which the Cronbach's alpha coefficient equaled to 0.7224-0.9099 among 22 items.


CONCLUSIONS
The Thai version of the LVQOL can be used as an instrument to evaluate the low vision quality of life. It is useful in determining the effects of the low vision rehabilitation.
