Validating care and treatment scenarios for measuring decisional conflict regarding future care preferences among older adults.

OBJECTIVE: Decisional conflict is used increasingly as an outcome measure in advance care planning (ACP) studies. When the Decisional Conflict Scale (DCS) is used in anticipatory decision-making contexts, the scale is typically tethered to hypothetical scenarios. This study reports preliminary validation data for hypothetical scenarios relating to life-sustaining treatments and care utilisation to inform their broader use in ACP studies. METHODS: Three hypothetical scenarios were developed by a panel of multidisciplinary researchers, clinicians and community representatives. A convenience sample of 262 older adults were surveyed. Analyses investigated comprehensibility, missing data properties, sample norms, structural, convergent and discriminant validity. RESULTS: Response characteristics suggested that two of the scenarios had adequate comprehensibility and response spread. Missing response rates were unrelated to demographic characteristics. Predicted associations between DCS scores and anxiety (r's = .31-.37, p < .001), and ACP engagement (r's = -.41 to -.37, p < .001) indicated convergent validity. CONCLUSION: A substantial proportion of older adults reported clinically significant levels of decisional conflict when responding to a range of hypothetical scenarios about care or treatment. Two scenarios showed acceptable comprehensibility and response characteristics. A third scenario may be suitable following further refinement. PATIENT OR PUBLIC CONTRIBUTION: The scenarios tested here were designed in collaboration with a community representative and were further piloted with two groups of community members with relevant lived experiences; four people with life-limiting conditions and five current or former care partners.

Measuring the success of programmes of care for people living with dementia: a protocol for consensus building with consumers to develop a set of Core Outcome Measures for Improving Care (COM-IC).

INTRODUCTION: The Core Outcome Measures for Improving Care (COM-IC) project aims to deliver practical recommendations on the selection and implementation of a suite of core outcomes to measure the effectiveness of interventions for dementia care. METHODS AND ANALYSIS: COM-IC embeds a participatory action approach to using the Alignment-Harmonisation-Results framework for measuring dementia care in Australia. Using this framework, suitable core outcome measures will be identified, analysed, implemented and audited. The methods for analysing each stage will be codesigned with stakeholders, through the conduit of a Stakeholder Reference Group including people living with dementia, formal and informal carers, aged care industry representatives, researchers, clinicians and policy actors. The codesigned evaluation methods consider two key factors: feasibility and acceptability. These considerations will be tested during a 6-month feasibility study embedded in aged care industry partner organisations. ETHICS AND DISSEMINATION: COM-IC has received ethical approval from The University of Queensland (HREC 2021/HE001932). Results will be disseminated through networks established over the project, and in accordance with both the publication schedule and requests from the Stakeholder Reference Group. Full access to publications and reports will be made available through UQ eSpace (https://espace.library.uq.edu.au/), an open access repository hosted by The University of Queensland.

The Medical Outcome Study Social Support Survey (MOS-SSS): A psychometric systematic review.

AIMS: To evaluate and synthesize psychometric properties of the MOS-SSS and to identify quality versions of MOS-SSS for use in future research and practice. DESIGN: A psychometric systematic review. DATA SOURCES: Articles about the translation, adaptation, or validation of the MOS-SSS in Medline, PubMed, CINAHL, and Web of Science and their reference lists published before 11 November 2022. REVIEW METHODS: The review followed the Consensus Standards for the Selection of Health Measurement Instruments guidelines. RESULTS: The review included 35 articles. Eleven versions of MOS-SSS (3, 4, 5, 6, 8, 12, 13, 16, 18, 19, and 22 items) have been validated in various populations and 13 languages. Of 14 studies developing a translated version of MOS-SSS, four studies performed both an experts' evaluation of content validity and a face validity test; two studies reported translation evaluation in the form of a content validity index. Of 35 studies, six performed both exploratory factor analysis and confirmatory factor analysis for structural validity; hypotheses and measurements for construct validity testings were often not clearly stated; two examined criterion validity; and four assessed cross-cultural validity. Internal consistency reliabilities were commonly examined by calculating Cronbach's alpha and reported satisfactory. Five studies analysed test-retest reliabilities using intra correlation coefficient. Methodological concerns exist. CONCLUSION: The English 19-item, Farsi Persian 19-item, and Vietnamese 19-item versions are recommended for future use in research and practice. Italian 19-item and Malaysian 13-item versions are not recommended to be used in future research and practice. All other versions considered in this review have potential use in future research and practice. Proper procedures for developing a translated version of MOS-SSS and validating the scale are recommended. IMPACT: The review identified quality versions of MOS-SSS to measure social support in future research and practice. The study also indicated methodological issues in current validation studies. Application of the study findings and recommendations can be useful to improve outcome measurement quality and maximize the efficiency of resource use in future research and practice. NO PATIENT OR PUBLIC CONTRIBUTION: This systematic review synthesized the evidence from previous research and did not involve any human participation.

Factors associated with self-management among Vietnamese adults with type 2 diabetes.

AIM: The study described diabetes self-management (DSM), diabetes knowledge, family and friends' support, healthcare providers' support, belief in treatment effectiveness and diabetes management self-efficacy, and explored DSM's associations among Vietnamese adults with type 2 diabetes mellitus (T2DM). DESIGN: A cross-sectional design was applied. METHODS: The study used self-report questionnaires to collect data from 198 participants. Descriptive statistics and structural equation modelling (SEM) was used for data analysis. RESULTS: Vietnamese adults with T2DM performed DSM limitedly in certain aspects. They had strong belief in treatment effectiveness, good family and friends support, limited diabetes knowledge, healthcare professional support and self-efficacy. Their DSM was directly associated with diabetes knowledge, family and friends' support, healthcare providers' support, belief in treatment effectiveness and diabetes management self-efficacy. Their DSM was indirectly associated with diabetes knowledge and family and friends' support through their belief in treatment effectiveness and diabetes management self-efficacy.

A cross-cultural comparison of health-related quality of life and its associated factors among older women in Vietnam and Australia.

OBJECTIVE: This study compared health-related quality of life and its associated factors among 305 women in Vietnam and 175 women in Australia aged 60-71. Descriptive analyses, Chi square, independent t-tests, and General Linear Models were used for data analysis. RESULTS: After controlling for socio-demographics, lifestyles, and chronic diseases, older women in Vietnam had lower levels of physical health but similar levels of mental health to those in Australia. In both populations, chronic disease and diet were associated with physical health; physical activity was related to mental health. In Australia, physical activity, exercise, and Body Mass Index were also associated with physical health; age, alcohol consumption, and sleep were also linked with mental health. In Vietnam, age and marital status were also related to physical health; chronic diseases and diet were also correlated with mental health. These findings suggested that interventions developed in Australia targeting the management of diet and physical activity, may be useful for older women in Vietnam. However, future interventions in Vietnam need to be tailored to account for different age groups, marital status, and the number of chronic diseases experienced. Further investigation into the contributions of cultural factors to health-related quality of life is recommended.

Prevalence and correlates of sleep disturbance among older women in Vietnam.

AIMS AND OBJECTIVES: To explore prevalence and correlates of sleep disturbance among women aged 60 and over in Vietnam. BACKGROUND: Sleep disturbance can negatively influence human's health. Sleep disturbance is likely to increase with age, and women appear to be more likely to experience sleep disturbance than men. Knowledge about sleep disturbance in women aged 60 and over in Vietnam is under-researched. DESIGN: The study presents results from a cross-sectional survey of 440 women aged 60 and over from 16 rural and urban suburbs in Vietnam from August 2014-January 2015 METHODS: Structured questionnaires were used to gather data about residence, age, marital status, educational attainment, employment status, income, body mass index, physical activity, exercise, perceived stress, general health status, number of chronic diseases and sleep disturbance. Descriptive analysis, bivariate correlation and binary logistic generalised linear model were used for data analysis. RESULTS: Among older women in Vietnam, (i) the prevalence of sleep disturbance was 38.9%; (ii) the most commonly problem was difficulty maintaining sleep, followed by sleep latency, reduced sleep quality, early waking and daytime sleepiness, (iii) body mass index and physical health were significantly associated with sleep disturbance status. CONCLUSIONS: Sleep disturbance was relatively common among older women in Vietnam. Overweight increased their sleep disturbance while physical health was negatively associated with their sleep disturbance. RELEVANCE TO CLINICAL PRACTICE: This article provided evidence about sleep problems among older women in Vietnam and suggested that interventions targeting weight control and physical health promotion would be useful to improve their sleep problems.

How life stressors influence modifiable lifestyle factors, depressive symptoms, and physical and mental health among Vietnamese older women?

BACKGROUND: Research has demonstrated that exposure to life stressors can influence health through a number of pathways. However, knowledge about the patterns of life stressors and their contributions to health in different populations is limited. Vietnamese older women have attracted little research to date in this area. METHODS: This cross-sectional study used an interview-administered-questionnaire to collect data from 440 Vietnamese older women. Descriptive analysis was used to describe life stressors among Vietnamese older women. Binary analysis and Structural Equation Modelling statistical analysis were used to examine the influences of life stressors on modifiable lifestyle factors, depressive symptoms, physical and mental health among Vietnamese older women. RESULTS: Vietnamese older women in this study commonly reported the experience of losing a close person, including a baby/child, serious health or money problems, violence and disaster. Among the study participants, (1) exposure to more life stressors increased their depressive symptoms, and decreased their physical and mental health; (2) exposure to more life stressors also increased their physical health by increasing their physical activity levels. CONCLUSION: Life stressors influenced health among Vietnamese older women through different pathways. Interventions to manage stress and depressive symptoms are required for Vietnamese older women in the future.

The Vietnamese version of the Perceived Stress Scale (PSS-10): Translation equivalence and psychometric properties among older women.

BACKGROUND: The Perceived Stress Scale 10 item (PSS-10) has been translated into more than 20 languages and used widely in different populations. Yet, to date, no study has tested psychometric properties of the instrument among older women and there is no Vietnamese version of the instrument. METHODS: This study translated the PSS-10 into Vietnamese and assessed Vietnamese version of the Perceived Stress Scale 10 items (V-PSS-10) for translation equivalence, face validity, construct validity, correlations, internal consistency reliability, and test-retest reliability among 473 women aged 60 and over. RESULTS: The study found that V-PSS-10 retained the original meaning and was understood by Vietnamese older women. An exploratory factor analysis of the V-PSS-10 yielded a two-factor structure, and these two factors were significantly correlated (0.56, p < .01) with all item loadings exceeded .50. The V-PSS-10 score was positively correlated with general sleep disturbance (ρ = .12, p < .05), CES-D score for depression symptoms (ρ = .60, p < .01), and negatively correlated with mental (ρ = -.46, p < .01), and physical health scores (ρ = -.19, p < .01). The Cronbach's alpha for the V-PSS-10 was .80, and the test-retest correlation at one month's interval was .43. CONCLUSION: Findings from this study suggest that the V-PSS-10 has acceptable validity and reliability levels among older women. The V-PSS-10 can be used to measure perceived stress in future research and practice. However, future research would be useful to further endorse the validity and reliability of the V-PSS-10.

Vietnamese Version of Diabetes Self-Management Instrument: Development and Psychometric Testing.

Self-management plays a vital role in diabetes management for adults with type 2 diabetes (T2DM). While there are many people with T2DM in Vietnam, clinical understanding of diabetes self-management (DSM) in this context is limited due to the lack of a valid measurement instrument. Translation and back-translation processes were used to translate the Diabetes Self-Management Instrument (DSMI) into Vietnamese. Then, translation equivalence, face validity, construct validity, and internal consistency were assessed in a sample of 198 Vietnamese adults with T2DM. The Cronbach's alpha of the V-DSMI was .92, with a number of significant inter-item correlations. The Vietnamese version of the Diabetes Self-Management Instrument (V-DSMI) retained the meaning of the original English version, and the language of the V-DSMI was clearly understandable to adults with T2DM in Vietnam. Confirmatory factor analysis supported the goodness of fit between the data and the previously identified factor structure. These results indicated that the V-DSMI is acceptable for use with Vietnamese adults with T2DM in further practice and research. However, future studies would be beneficial to determine the test-retest reliability and criterion validity of the V-DSMI. © 2016 Wiley Periodicals, Inc.
