Psychometric properties of the Czech version of the brief Older People Quality of Life questionnaire (OPQoL-brief)

Abstract

Background To evaluate the established interventions used for older adults, it is appropriate to use validated questionnaires for quality-of-life assessment. For older people, it is suitable to use specific questionnaires designed for old age and aging, with a lower number of questions. The aim of this research was to verify the psychometric properties of the Czech version of the OPQoL-brief questionnaire for seniors living in home environment in a community so that it can be used within the Czech Republic. Methods A cross-sectional study was performed on older adults in the Moravian-Silesian Region living at home. The study included 954 senior citizens (≥ 65 years, cognitively intact) (without diagnosed dementia, able to sign an informed consent). To test the psychometric properties of the created questionnaire, we tested the validity (construct validity, discriminant validity, convergent validity) and reliability (internal consistency, test–retest reliability). Results The single-factor model of the OPQoL-brief scale (CFI = 0.971, TLI = 0.959, RMSEA = 0.061, SRMR = 0.034, GFI = 0.960) was confirmed, for which excellent reliability was found (α = 0.921, ICC = 0.904). An inter-item correlation exceeding 0.5 was found for all items. Furthermore, a significant correlation was found between the overall score of OPQoL-brief and the scales measuring depression (r = − 0.520; p < 0.001), anxiety (r = − 0.355; p < 0.001), sense of coherence (r = 0.427; p < 0.001), and self-esteem (r = 0.428; p < 0.001). Conclusion The results of our research revealed that the shorter Czech version of the OPQoL-brief questionnaire has appropriate reliability and validity and can be recommended for both health and social services to assess the quality of life of senior citizens in a community.

The Czech version of the life satisfaction index for the third age—short form (LSITA‐SF12): Psychometric properties

“…It includes items such as enjoying one's life, looking forward to things, staying involved in things, feeling safe where one lives, being healthy and having independence, feeling lucky and having enough money. The Czech version of the OPQOL‐Brief was developed and validated by Bužgová et al (2022) and has good reliability (internal consistency) and validity (structural, convergent and discriminant).…”

“…The OPQOL questionnaire is not based solely on the concept of subjective fulfilment of dimensions of human life like the LSITA‐SF12 but combines multidimensional components. However, we chose this questionnaire due to its availability in Czech (Bužgová et al, 2022; Mareš et al, 2016) and its focus on an older population.…”
