Meranie kvality života: analýza prehľadových štúdií evidovaných vo vybraných databázach

b1_The paper conducts a survey of the state of quality of life measurement on the basis of analysis of overview studies included in EBSCO and Proquest publication data-bases. The analyzed studies were selected according to these criteria: a) authors of overview studies accomplished a systematic research of literature from publication data-bases; b) concept of quality of life was declared by the title or abstract; c) the evaluation of psychometric or clinimetric parameters of measurement was included in the study. From 64 identified studies, 17 were selected for analysis focused on four characteristics of analyzed procedures and instruments: a) what are the theoretical starting points for quality of life measurement, b) how were the evaluated instruments classified into the categories, c) what are their psychometric/clinimetric parameters, and d) what are the recommendations of authors of overview studies concerning quality of life measurement. In theoretical starting points of particular instruments the relative agreement in defining the construct of quality of life was found but big differences in using this construct in measuring, and the confusion of quality of life and „health-related quality of life“ concepts was identified. Concerning the type of the used instrument the typical differentiation is specific and generic instruments. The specific ones are more sensitive to change and differences between groups but they do not make possible the wider comparison between different categories of respondents. In psychometric parameters of evaluated instruments the absence of verifying the test-retest reliability and nonadequate procedures were found, missing the content and construct validity of the instrument respectively. The responsiveness indicator was the most used clinimetric parameter, its absence was one of often stated deficiencies.
