Design And Methods

Purpose. To present the psychometric properties of a new measure of quality of life in older age, the Older People's Quality of Life (OPQOL) Questionnaire, compared with the CAPSE-19 and the WHOQOL-OLD.Design and Methods. The vehicle was three national population surveys of older people living at home in Britain, including a survey of ethnically diverse older people.Results. The OPQOL had acceptable levels of reliability and validity in British population samples of older people, but more modest in the ethnically diverse population sample. The CASP-19 and WHOQOL-OLD had acceptable levels of reliability and validity in the British population sample, but not in the ethnically diverse sample.Implications. The OPQOL has potential for use as a multidimensional population surveillance instrument for use with older populations, or as an outcome measure of multisector policy. Its strengths are that its development was embedded firmly in the perspectives of older people, integrated with theory.

Aim.This study aimed to test the Russian version of GERD-HRQL in the focus group of patients with GERD, as well as to evaluate its psychometric properties reliability, validity and sensitivity. Materials and methods.The total of 57 patients with GERD (mean age 45.812.4 years, 72% women, 68% patients with not erosive reflux disease, 84% had esophageal manifestations of GERD) were enrolled into the study. All the patients filled out the Russian version of GERD-HRQL and generic quality of life questionnaire RAND SF-36 during the routine visit to the gastroenterologist. According to the results of testing of GERD-HRQL, it was clear and easy to complete for patients and reflected the main concerns specific for GERD patients. The most frequent and bothersome symptoms/problems which interfered with quality of life in GERD patients were heartburn (100% of patients) and bloating (84% of patients). During the validation procedure, the high reliability and validity of the Russian version of GERD-HRQL were demonstrated. It was shown that the tool was sensitive both to changes over time and to clinically determined differences in patients status. Results.The Total GERD-HRQL Score was significantly higher (worse quality of life) in the following groups: a) patients who had esophageal manifestations of GERB vs those without esophageal manifestations of GERB; b) patients with GERD complications vs those without GERD complications, c) patients with comorbidities of upper gastrointestinal tract vs without those comorbidities; d) patients with erosive esophagitis vs with non-erosive reflux disease (p0.05). Conclusion.The developed Russian version of the GERD-HRQL questionnaire proved to have high psychometric properties and may be used in the Russian population of GERD patients both in research studies and in a real clinical practice.

Abstract Background: The proportion of older people aged more than 65 years old is continuously increasing in the world population. The quality of life is an important factor in their biopsychosocial handling. The questionnaire “Older People’s Quality of Life-35” (OPQOL-35) has been specially developed for the assessment of the senior’s quality of life. The aim of this study is to translate and evaluate the psychometric properties of the transcultural Swiss French version of the OPQOL-35 questionnaire (OPQOL-35-SF). Method: Forward-backward procedure was applied to translate the original questionnaire from English into Swiss French. Then, a sample of older people completed the questionnaire. The construct validity was evaluated by comparing the results of the OPQOL-35-SF with the scores of three other questionnaires (WHOQOL-OLD, CASP-12 and EQ-5D-5L) and two visual analogue scales (health and quality of life). The questionnaire’s structure has been assessed through exploratory and confirmatory factor analysis. The OPQOL-35-SF questionnaire was submitted a second time after 7 to 23 days to evaluate the reliability. Results: 264 older people completed all the questionnaires once and 262 the OPQOL-35-SF a second time. The mean age of participants was 76.8 (SD = 7.1). Most of them were women (73,9%). KMO is of 0.86 and the Bartlett’s test of sphericity is significant (p<0.001). The result of EFA shows 8 factors with eigenvalues greater than one, which explained 58% of the observed variance. All the items have a significant impact (<0.30) in at least one factor. The convergent validity presents low to moderate correlations (rho: 0.384-0.663). Internal consistency is good with a Cronbach’s alpha at 0.875 for test and at 0.902 for retest. Test-retest reliability presents an ICC2.1 at 0.83 (IC 0.78 to 0.87). Conclusion: The Swiss French version of the questionnaire OPQOL-35 shows psychometric properties which permit its use in the clinical practice or for research purposes. A supplementary sample would be necessary for a better repartition of the items in the different factors.

Objective: To translate and adapt to the Moroccan context the diabetes-39 questionnaire, and to assess the psychometric properties of the adapted version among Moroccan patients with diabetes. Materials and Methods: The questionnaire was translated from English to spoken Arabic, then back translated to English. A consensus meeting discussed discrepancies and major changes. The adapted version was administered to 92 patients with type 2 diabetes to assess its psychometric properties. Inter-item correlation, item-to-dimension correlation, and Cronbach’s alpha were calculated to assess internal consistency. Additionally, construct validity was assessed using means comparison of domains scores according to the general perception of the quality of life and the perception of disease severity. Results: Participants’ mean age was 56.4 ± 10.9. The sample was constituted predominantly by women. Cronbach’s alpha ranged from 0.65 for “social burden” and 0.93 for “diabetes control”. Items showed a higher correlation with their own domain as compared to other domains. Higher scores of the five domains of the diabetes-39 were associated with the perception of lower quality of life and higher disease severity. Conclusion: The results of this study support the reliability and validity of the Moroccan version of the diabetes-39 questionnaire. They justify its use and further assessment among our patients with diabetes.

Abstract 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.

Introduction: Ageing is associated with several physical, psychological, and behavioral changes. These changes are closely related with general health problems and quality of life in old age. The CASP-19 multidimensional instrument was specially designed to measure quality of life in the elderly. The different language versions of this scale have been used in more than 20 countries. However, Lithuanian translation was not available. The objective of our study was to test psychometric properties of the Lithuanian version of the CASP-19 questionnaire. Materials and methods: A cross-sectional study was performed with ambulatory men and women aged 60 and older, living in a community in Vilnius, Lithuania. Exclusion criteria were current acute illness, malignant tumor, and Mini-Mental State Examination (MMSE) score < 25 points. Psychometric properties of CASP-19 were tested using reliability and validity methods. Results: The study sample consisted of 132 participants, 28 (21.8%) of them were men and 103 (78.2%) women. Analysis of psychometric properties of the Lithuanian version of CASP-19 showed high internal consistency (Cronbach’s alpha 0.85), good agreement between test-retest measures with an ICC of 0.82 (95% CI 0.79–0.85) and good convergent and divergent construct validity. Conclusions: The psychometric properties indicated that the Lithuanian version of CASP-19 was reliable and valid. As such, it might be used to evaluate quality of life in elderly people.

Objective: Recent years have shown an increase in the use of questionnaires measuring health-related quality of life to verify the quality of treatment in the field of oncology. An often used cancer-specific questionnaire is the “Quality of Life Core Questionnaire of the European Organization for the Research and Treatment of Cancer” (EORTC QLQ-C30). The purpose of this study is to analyze the psychometric properties of the EORTC QLQ-C30 (version 1) in order to determine the feasibility and appropriateness for its use in inpatient cancer rehabilitation in Germany with heterogeneous diagnoses.Methods: The questionnaire was administrated to a sample of 972 cancer patients at the beginning of treatment and to 892 patients after treatment. Besides descriptive analysis, the statistical analyses include confirmatory analysis and the multitrait/multimethod approach to test the questionnaire's postulated scale structure (factorial validity) and its reliability (internal consistencies). The analysis also includes a comparison of responsiveness indices (effect size, reliable change index) to test the sensitivity of the instrument.Results: The EORTC QLQ-C30 showed satisfactory levels of reliability and sensitivity, but the postulated scale structure could not be confirmed. The results illustrate that the varimax-rotated solution of a principal component analysis does not confirm the scale structure postulated by the authors. Correspondingly, the selected fit indices within the scope of the confirmatory factor analysis do not show satisfactory results either.Significance of results: We therefore consider version 1 of the EORTC QLQ-C30 to be only limitedly useful for the routine assessment of changes in the quality of life of cancer patients in inpatient rehabilitation in Germany, especially because of the instrument's length and possible redundancies. For this reason, a scoring procedure limited to a subset of items is suggested, revealing satisfactory to good psychometric indices. However, further psychometric tests are necessary, especially with regard to validity and sensitivity.
