[A note on application of the WHOQOL-BREF questionnaire on quality of life in the Czech enviroment]. / Poznámka k pouzití dotazníku kvality zivota WHOQOL-BREF v ceském prostredí.

In the Czech environment, the WHOQOL-BREF (WHO Quality of Life-BREF) questionnaire has been rather frequently used for quality-of-life assessment in the case of different diseases or different health limitations. The questionnaire exists in two Czech translations with different wording. The differences are so considerable that they might cause interpretation shifts in research based on this instrument. Also the reverse scales in three questions may cause problems, because processing of these scores is not described correctly in some methodological materials. The authors recommend to strictly use the version published by Dragomirecká and Bartonová of the Prague Psychiatric Centre.
