ABSTRACTBackground: As ageing is a personal experience, an attitude to ageing questionnaire is essential for capturing the most realistic appraisal of this important stage of life. Our aim was to study the psychometric properties of the Attitudes to Ageing Questionnaire (AAQ) in a sample of Spanish older people.Methods: A total of 242 participants aged 60 years and older were recruited from community centers, primary care centers, and family associations for the mentally ill and dementia. In addition to the AAQ, participants provided information on demographics, self-perception of health, comorbidity, health status (SF-12), depressive symptoms (GDS-30), and quality of life (WHOQOL-BREF and WHOQOL-OLD). Analysis was performed using standard psychometric techniques with SPSS v15.0.Results: No floor and ceiling effects were found, and missing data were low. The internal consistency measured by Cronbach's alpha for AAQ subscales were 0.59, 0.70, and 0.73. Exploratory Factor Analysis produced a three-factors solution accounting for 34% of the variance. A priori expected associations were found between some AAQ subscales with WHOQOL-BREF domains, with WHOQOL-OLD, SF-12, and the GDS-30 indicating good construct validity. In general, AAQ subscales differentiated between participants with lower and higher levels of education, and between a priori defined groups of older people (non-depressed vs. depressed; those with higher vs. lower physical comorbidities, and non-carers vs. carers).Conclusions: The Spanish version of the AAQ questionnaire showed acceptable psychometric properties in a convenience sample of Spanish older people. It is a useful measure of attitude for use with older people in social and clinical services.

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.

Background: As our understanding of the nature and prevalence of Post-COVID-19 syndrome (PCS) is increasing, a measure of the impact of COVID-19 could provide valuable insights into patients' perceptions in clinical trials and epidemiological studies, as well as routine clinical practice. Objective: To evaluate the clinical usefulness and psychometric properties of the COVID-19 Yorkshire Rehabilitation Scale (C19-YRS) in patients with PCS. Design: A prospective, observational study of 187 consecutive patients attending a post-COVID-19 rehabilitation clinic. The C19-YRS was used to record patients' symptoms, functioning and disability. A global health question was used to measure the overall impact of PCS on health. Classical psychometric methods (data quality, scaling assumptions, targeting, reliability and validity) were used to assess the C19-YRS. Results: For the overall scale, missing data were low, scaling and targeting assumptions were satisfied, and internal consistency was high (Cronbach's alpha = 0.891). Relationships between perception of health and patients' reports of symptoms, functioning and disability demonstrated good concordance. Conclusions: This is the first study to examine the psychometric properties of an outcome measure in patients with PCS. In this sample of patients, the C19-YRS was clinically useful and satisfied standard psychometric criteria, providing preliminary evidence of its suitability as a measure of PCS.

Objectives: To translate and validate a recently developed quality of life instrument (WHOQOL-AGE) on geriatric population into Chinese.Method: Using cross-sectional observational design, the WHOQOL-AGE was conducted among older people through interview. Confirmatory factor analysis (CFA) was used to examine the factor structure and multigroup CFA used to examine the measurement invariance.Results: Through convenience sampling, 522 older adults (mean age = 73.42) participated in the study. Among them, 194 were males, 213 had an educational level at primary school or below, 398 were residing in the community, and 307 were aged 70 years or above. A bifactor structure (items Q1–Q8 are embedded in the factor 1; items Q9–Q13 embedded in the factor 2; and all the items embedded in an additional construct of QoL) was confirmed by the CFA in both the entire sample (χ2 = 25.4; df = 51; p = 0.999) and the subgroup sample with age 70 years or above (χ2 = 25.28; df = 51; p = 1.000). Multigroup CFAs results supported the measurement invariance for the WHOQOL-AGE across genders, having different educational levels, living in different settings and age groups. It also shows good known-groups validity.Conclusions: The promising psychometric properties of the WHOQOL-AGE were found in our convenience sample of older Taiwanese. The supported measurement invariance indicates that the older people in different conditions of gender, educational level, and living setting interpret the WHOQOL-AGE similarly. However, our results should be interpreted with cautious because of the sample representativeness.

Abstract Objectives To develop and validate a set of 3 quality assessment instruments (QAls) for evaluating the quality of nutrition studies, for each of the commonly used study designs: (1) randomized controlled trials (RCTs), (2) prospective cohort, and (3) case-control studies. Methods The QAI development and validation process included 8 steps: 1) identify and evaluate existing general QAls for adaptation with nutrition-specific quality appraisal items; 2) scan the literature to identify nutrition-specific quality appraisal issues; 3) generate nutrition-specific items to be added to each of the general QAIs, adapt existing guidance for general items for nutrition applications and develop guidance for added nutrition items; 4) review, by two experts in clinical and population nutrition, of the modified general QAIs with added nutrition-specific items and guidance; 5) assess reliability and validity of the QAI for each study design; 6) improve the usability and feasibility, of the QAIs by considering feedback from the validation exercise to refine the wording of the guidance; 7) develop a worksheet to help evaluate, a priori, topic-specific methodology to address risk of bias; and  8) validate the final QAIs using five peer-reviewed studies identified from published systematic reviews with reported quality assessment. Agreement and reliability were determined for each QAI. Results Results of the validation show good to perfect agreement among evaluators for the overall study rating and across domains. When compared to the study quality assessment reported in the systematic review, nutrition- specific items had the greatest impact on study ratings, generally resulting in a downgrade of the overall rating. Conclusions A set of nutrition-specific QAls were developed to assess the quality and robustness of nutrition studies. These tools incorporate general quality issues of study design and conduct, as well as address recognised nutrition study-specific issues. They will improve consistency in how nutrition studies are assessed particularly in nutrition-related systematic reviews. This will contribute to the overall quality of assessment of diet and Funding Sources This work was supported by Health Canada.

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.

Nursing Home Population

Abstract Background Well-adapted and validated quality-of-life measurement models for the nursing home population are scarce. Therefore, the aim of this study was to test the psychometrical properties of the OPQoL-brief questionnaire among cognitively intact nursing home residents. The research question addressed evidence related to the dimensionality, reliability and construct validity, all of which considered interrelated measurement properties. Methods Cross-sectional data were collected during 2017–2018, in 27 nursing homes representing four different Norwegian municipalities, located in Western and Mid-Norway. The total sample comprised 188 of 204 (92% response rate) long-term nursing home residents who met the inclusion criteria: (1) municipality authority’s decision of long-term nursing home care; (2) residential time 3 months or longer; (3) informed consent competency recognized by responsible doctor and nurse; and (4) capable of being interviewed. Results Principal component analysis and confirmative factor analyses indicated a unidimensional solution. Five of the original 13 items showed low reliability and validity; excluding these items revealed a good model fit for the one-dimensional 8-items measurement model, showing good internal consistency and validity for these 8 items. Conclusion Five out of the 13 original items were not high-quality indicators of quality-of-life showing low reliability and validity in this nursing home population. Significant factor loadings, goodness-of-fit indices and significant correlations in the expected directions with the selected constructs (anxiety, depression, self-transcendence, meaning-in-life, nurse-patient interaction, and joy-of-life) supported the psychometric properties of the OPQoL-brief questionnaire. Exploring the essence of quality-of-life when residing in a nursing home is highly warranted, followed by development and validation of new tools assessing quality-of-life in this population. Such knowledge and well-adapted scales for the nursing home population are beneficial and important for the further development of care quality in nursing homes, and consequently for quality-of-life and wellbeing in this population.

Overall Health Status

Quality of life (QoL) instruments for children provide an important health index for school healthcare professionals to understand students’ overall health status. We investigated the psychometric properties of the Chinese version of the widely used Kid-KINDL and reported on the wording effect of its positively and negatively worded items. A convenience sample of 8- to 12-year-old students (n = 443) completed the Kid-KINDL; 89 of them completed it again 7–14 days later. The internal consistency was satisfactory in the total score (α = .87) and two subscales (α = .704 [emotional] and .853 [self-esteem]), but unsatisfactory for the other subscales (α = .578 [physical], .533 [friend], .520 [family], and .560 [school]). Test-retest reliability was acceptable in all the subscales and the total score (ICC > .6). A multitrait-multimethod design using several confirmatory factor analysis models confirmed the construct validity of the Kid-KINDL when the wording effect was taken into account (GFI = .912–.934, TLI = .889–.930, CFI = 0.910–.947, IFI = 0.912–0.948, RMSEA = 0.045–0.057, SRMR = .045–.056). We conclude that the Kid-KINDL is a reliable and valid tool for teachers to use to evaluate students’ QoL if the total score is used.

Patient satisfaction with health services is used as a measure of the quality of patient care received. The emphasis on accountability and patient as consumer has contributed to the growing interest in studying patient satisfaction. Patient satisfaction with prenatal care services has not been extensively studied including instrumentation to develop a satisfaction scale. The purpose of this study was to develop a reliable and valid scale to measure satisfaction with prenatal care services in St. Petersburg, Russia, using the 6 satisfaction dimensions in Aday and Andersen’s Theoretical Framework (1974). It was conducted under the auspices of the World Health Organization, Healthy Cities Project. Although the study was conducted internationally, it provides a basis for further testing of reliability and validity in the United States. A convenience sample of 397 women with uncomplicated pregnancies and normal deliveries was studied (86% response rate). Content, construct, and predictive validity, and reliability testing using Cronbach’s alpha was conducted. The scale was found to be an adequate and theoretically sound measure of satisfaction with prenatal care services in Russia. However, rather than the 6 hypothesized satisfaction dimensions, Russian women identified 2 satisfaction subscales or measures for quality of prenatal care received. One was, as hypothesized, convenience, and the other was the doctor’s behavior.

The psychometric properties of the Father and Mother Scales of the Parent-Child Relationship Survey were examined. 149 undergraduate students in psychology from divorced families and 155 students from continuously intact families completed the instrument which was designed to assess the perceived quality of older children's relationships with their parents. Results suggest that the Father and Mother Scales each assess primarily a unidimensional positive affective component of perceived parent-child relationships. Normative, reliability, and validity data are also presented. These findings support the research and clinical utility of the instrument.

This study examined the psychometric properties of the Chinese version of the Personal Diabetes Questionnaire (C-PDQ). The PDQ was translated into Chinese using a forward and backward translation approach. After being reviewed by an expert panel, the C-PDQ was administered to a convenience sample of 346 adults with Type 2 diabetes. The Chinese version of the Summary of Diabetes Self-Care Activities (C-SDSCA) was also administered. The results of the exploratory factor analysis revealed a one-factor structure for the Diet Knowledge, Decision-Making, and Eating Problems subscales and a two-factor structure for the barriers-related subscales. The criterion and convergent validity were supported by significant correlations of the subscales of the C-PDQ with the glycated hemoglobin values and the parallel subscales in the C-SDSCA, respectively. The C-PDQ subscales also showed acceptable internal consistency (α = .61–.89) and excellent test–retest reliability (intraclass correlation coefficients: .73–.96). The results provide preliminary support for the reliability and validity of the C-PDQ. This comprehensive, patient-centered instrument could be useful to identify the needs, concerns, and priorities of Chinese patients with type 2 diabetes.
