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.

Background Evaluation of life satisfaction of older people using standardised tools can play a crucial role in evaluating the effectiveness of policy measures aimed at mitigating the effects of population aging. Objectives The aim of the study was to verify the psychometric properties of the Czech version of a 12‐item scale (the Life Satisfaction Index for the Third Age) for older people living in the community. Methods The research involved 1113 older people from the Moravian–Silesian Region over 60 years of age living in a home environment. For the newly created Czech version of LSITA‐SF12, we tested validity (construct validity and convergent validity) and reliability (internal consistency). Results We confirmed a single‐factor model for the LSITA‐SF12 scale (χ2 = 71.33, p <  .001, CFI = 0.995, TLI = 0.994, RMSEA = 0.065, SRMR = 0.056, GFI = 0.999) by confirmatory factor analysis and load factor analysis (values of explorations ≥0.45). The internal consistency of the scale was satisfactory (α = 0.878). Furthermore, there was a medium correlation rate (r = 0.592; p <  .001) between the overall score of the LSITA‐SF and quality‐of‐life score (OPQoL‐Brief). Conclusions We found the Czech version of the LSITA‐SF12 questionnaire to have satisfactory psychometric properties. The questionnaire is suitable for use in research and clinical practice to evaluate the effectiveness of preventive measures. Clinical Trial Registration: ClinicalTrials.gov. PRS Protocol Registration and Results System; NCT05637177. Implication for practice The LSITA_SF12 questionnaire can beadministered by a community gerontological nurse and can be used in clinicalpractice and research.

Objectives The aim of this cross-sectional study was to determine the life satisfaction of older people living in a home environment and to find out what predictors influence it. Methods The research involved 1,121 older people 60 years and above from the Moravian-Silesian region who live in a home environment. The short form of the Life Satisfaction Index for the Thirds Age (LSITA-SF12) was used to assess life satisfaction. The Geriatric depression scale (GDS-15), the Geriatric Anxiety Inventory Scale (GAI), The Sense of Coherence Scale (SOC-13), and the Rosenberg Self-Esteem Scale (RSES) were used to evaluate related factors. In addition, age, gender, marital status, education, social support, and subjective health assessment were evaluated. Results The overall life satisfaction score was found to be 36.34 (s = 8.66). The satisfaction of older people was classified into four grades: high satisfaction (15.2%), moderate satisfaction (60.8%), moderate dissatisfaction (23.4%), and high dissatisfaction (0.6%). The predictors of the longevity of the lives of older people were confirmed, both health factors (subjective health assessment, anxiety, and depression [Model 1: R = 0.642; R2 = 0.412; p<0.000]) and psychosocial factors (quality of life, self-esteem, sense of coherence, age, and social support [Model 2: R = 0.716; R2 = 0.513; p<0.000]). Conclusion In implementing policy measures, these areas should be emphasized. The availability of educational and psychosocial activities (e.g. reminiscence therapy, music therapy, group cognitive behavioural therapy, cognitive rehabilitation) within the community care of the older people and university of third age is appropriate to increase the life satisfaction of the older people. An initial depression screening is also required as part of preventive medical examinations to ensure early diagnosis and treatment of depression.
