Abstract
Abstract The aim of the study was to verify the psychometric properties and the suitability of the Subjective Assessment of Quality of Life questionnaire (SAQL; Džuka, 2014) for use with seniors. The participants were 141 Slovak respondents aged 60-75 (M = 67.44, SD = 4.6). The values of the internal consistency of the subscales of the questionnaire representing four significant domains of quality of life- physical, cognitive, psychosocial and environmental-suggest the instrument has good reliability (α = .79 - .86). Construct validity was demonstrated on the basis of moderately strong to strong correlations between SAQL domains and domains with similar content in the generic instrument, WHOQOL-BREF (WHOQOL Group, 1998), and also a separate module-measuring the spiritual domain of quality of life (SDQL). The multi-factor ANOVA results demonstrated that the score obtained for the different scales is not dependent on the gender, marital status and education of the seniors although an exception was a physical domain, in which a significant effect of education was detected. This can be considered to support the discriminatory validity of the test methodology. The SAQL questionnaire can be considered an appropriate generic instrument for measuring subjective assessment of quality of life in the early senior age group.
