“…According to the statistical data from population and housing census in 2011, Iran had 8.2% of people aged ≥ 60 years, and predicted that this rate will increase to 25.1% in 2061 [1,4,5]. The increase in the ageing population and corresponding rises in chronic illness is one of the most important public health challenges in the high-income countries [1,6,7]. In particular, it is associated with higher demand for, expenditure on, health and aged care services [8,9].…”

Background and objective Quality of life (QoL) is a multi-dimensional concept and its assessment is one of important themes of care for older people. Assessing QoL in older people needs specific scales. The aim of this study was to culturally adapt and investigate the psychometric properties of the Persian version of brief Older People’s Quality of Life questionnaire (OPQOL-brief) in an Iranian older population. Methods This methodological cross-sectional study was conducted among 525 Persian-speaking older people (aged 60 and over), living in Isfahan, Iran. Translation of the OPQOL-brief questionnaire was performed using forward–backward method. Test–retest reliability was evaluated through Intra Class Correlation (ICC) coefficient and internal consistency by using Cronbach’s α. Construct validity was investigated by using exploratory factor analysis (EFA), confirmatory factor analysis (CFA), and Latent class analysis (LCA). Criterion, convergent and discriminant validities were also assessed. Results Persian version of the OPQOL-brief showed good test–retest reliability (ICC = 0.842, 95% CI = 0.73–0.91; P < 0.001). Persian OPQOL-brief scale demonstrated high internal consistency (Cronbach’s α = 0.83). It showed good discriminant validity and differentiated old patients from healthy older individuals (P < 0.001). Construct validity based on EFA led to extraction of three dimensions (“socioeconomic”, “emotional”, and “physical” well-being) and the CFA confirmed the adequacy of extracted construct from EFA (CFI = 0.909, PCFI = 0.52, PNFI = 0.5, CMIN/DF = 3.012, and RMSEA = 0.08). LCA classified participants into three classes in terms of QoL level (low (16%), middle (67%), and high (17%)). Criterion validity and convergent validity revealed significant positive correlations between OPQOL-brief and physical and psychological dimensions of the SF-36. Conclusion The Persian version of the OPQOL-brief is a reliable and valid instrument for assessing QoL with applicability in a broad range of older Persian language population.

“…OPQOL-35 has been designed by Bowling and Stenner and its psychometric properties were evaluated in 2011. The reliability and validity of this questionnaire and its Persian version was confirmed in some studies (Jokinen, 2014;Nikkhah et al 2017). The questionnaire is a 5-point Likert-type scale that rates Quality of Life from (Strongly agree) to (Strongly disagree) and consists of 35 items of religion/culture (2 items), health (4 items); overall life (4 items); area: home and neighborhood (4 items); financial status (4 items); psychological and emotional wellbeing (4 items); freedom, independence, control over life (5 items); and social relationships and participation (8 items).…”

Background: Because of the rising number of elderly people, their Quality of Life have become more important. Health status has been considered as one of the factors that affect life quality and Spiritual Well-Being is one of its important dimensions. The present study aimed to determine the relationship between Spiritual Well-Being and Quality of Life among the elderly people residing in Arak City, Iran. Methods: This is a cross-sectional and correlational study. The study sample comprised 400 elderly people residing in Arak, Iran who were selected by cluster sampling method. Spiritual Well-Being was measured using Spiritual Well-Being scale (SWB) and the Quality of Life was assessed by Older People's Quality of Life Questionnaire (OPQOL-35). The obtained data were analyzed by descriptive statistics, along with Pearson correlation test, t-test, and ANOVA in SPSS V. 16. Results: The Mean±SD score of life quality among the elderlies was 76.24±17.84 and was associated with their marital status and education level (P=0.001). The Spiritual Well-Being score of most elderly people ranged from moderate to high and the Mean±SD score of their Spiritual Well-Being was 96.47±13.43. There was a significant relationship between Spiritual Well-Being and the Quality of Life (r=0.37, P=0.0001). Conclusion: According to the findings, more attention should be paid to the factors related to the Quality of Life for taking care of the elderly people. Considering the relationship between Spiritual Well-Being and Quality of Life among these elderlies, provision of spiritual care for this group of society is recommended.

“…was excluded. It might therefore be questioned whether the high total Cronbach's alpha coefficient observed for the entire scale can be interpreted as indicating a unidimensional measure [53]. However, the corrected item-total correlations were well above the limit of 0.30 [36], indicating that the items are measuring the same underlying construct.…”

Background: The worries of next of kin about their older loved ones in nursing homes can be extensive and can adversely affect their subjective experiences of their own physical, mental and social well-being. It is thus of utmost importance to measure the quality of life of next of kin in a valid and reliable way. Methods: The design is a cross-sectional study with psychometric evaluation based on classical test theory in preparation for a planned educational intervention study on palliative care. An abbreviated version of the World Health Organization's quality-of-life self-assessment instrument WHOQOL, the Swedish WHOQOL-BREF, was completed by 254 next of kin of older persons in 30 nursing homes. Data quality was assessed via the mean, median, item response, missing values, and floor and ceiling effects. Reliability was estimated using Cronbach's alpha and corrected item-total correlations. Construct validity was estimated by Spearman's rank correlation, and model fit was assessed using confirmatory factor analysis. Results: The rate of missing data was low (less than 2%). Ceiling effects ranged from 11 to 43% and were above 20% for 21 of 24 items. The corrected item-total correlations varied between 0.35 and 0.68 and were thus well above the lower limit of 0.30. Cronbach's alpha was 0.83, indicating satisfactory internal consistency. The confirmatory factor analysis indicated a fair to close model fit (comparative fit index 0.93, root mean squared error of approximation 0.06). Conclusions: The findings suggest that the WHOQOL-BREF may constitute a reliable and valid measure of quality of life for use among next of kin to older persons in nursing homes. When interpreting the results, it is important to assess the ceiling effect, as it may restrict the ability of the WHOQOL-BREF to detect true positive changes in quality of life over time. Trial registration: NCT02708498.
