Sample and setting. Sample of participants consisted of 403 seniors (75 males, 228 females, average age 70.7 ys, SD = 7.72, range 60 - 91 ys, selected by quota system according to gender, age, and region.
Results. Bifactor confirmatory analysis and the degree of agreement of data with Rasch's model acceptably supported the one-dimensional structure of the tool and can be recommended as a screening questionnaire for estimating quality of life of seniors older than 60 years, especially in cases where it is necessary to limit the time and cognitive burden of respondents.
