Objectives. The SF-8 Health Survey Questionnaire is an effective health-related quality of life (HRQOL) measurement tool consisting of eight items. The aim of the study was to verify the factor structure of the Czech version of the questionnaire, to describe the basic psychometric properties of the tool, to develop a basis for the creation of standards based on the analysis of the results from a representative sample and to compare the global scores between respondents with and without chronic health problems. Sample and settings. A nationally representative sample of 1800 Czech respondents (N = 1800, age 46.4, SD 17.4, 48.7% men) participated in the survey focused on health issues. Results: Females achieved lower scores in all items compared with males, except for physical functions and total physical health. With increasing age, the individual items, as well as the PCS (physical component summary) and the MCS (mental component summary) scores, declined for both genders. Thus, higher age was associated with worse subjective health status. Respondents with higher education showed a higher quality of life in the sphere of both mental and physical health experience. The study revealed differences between healthy and chronically ill patients with back pain, hypertension, depression, allergy and migraine for all diseases in the overall PCS and MCS scores. In order to assess the number of factors, the Kaiser criterion, scree plot, Parallel Analysis (PA) and Minimum Average Partial test (MAP) were used. All of these methods resulted into a two-factor solution. Confirmation factor analysis confirmed the model’s compliance for our data. A Cronbach’s alpha of 0.92 and McDonald’s coefficient omega with a value of 0.94 showed that the Czech version of the SF-8 Health Survey is a tool with high internal consistency and reliability. Conclusion. The Czech version of the SF-8 Health Survey is a tool with high internal consistency and reliability.
