Aims: The study aimed to develop and evaluate the effects of a self‐determination theory‐based, nurse‐led, physical activity programme for postmenopausal women with rheumatoid arthritis. Methods: Between December 2019 and April 2020, this randomized controlled trial recruited 62 postmenopausal women with rheumatoid arthritis from a university‐affiliated hospital in South Korea. The intervention group participated in a self‐determination theory‐based, nurse‐led, physical activity programme that consisted of Tai Chi‐based physical activity, a supportive psychosocial strategy, and interactive counselling for 16 weeks, and the control group continued to undergo their usual care. Results: There were statistically significant group‐by‐time interactions in physical activity and perceived sarcopenia, which favoured the intervention group. Additionally, the intervention group showed significant improvements in the perceived therapeutic efficacy of physical activity, grip strength, walking speed, disease activity score, and health‐related quality of life. Conclusions: The programme developed in this study can be an effective and feasible approach for postmenopausal women with rheumatoid arthritis in improving physical activity, selected osteosarcopenic outcomes, and health‐related quality of life. Further research is required to investigate the long‐term effects of this theory‐based programme for postmenopausal women in diverse settings. Summary statement: What is already known about this topic? Tai Chi‐based physical activity has been known to be a component of self‐management for rheumatoid arthritis. What this paper adds? It highlights the efficacy of a theory‐based, nurse‐led, physical activity programme to improve the quality of life of postmenopausal women with rheumatoid arthritis.The evidenced‐based programme could be transferred to postmenopausal women with rheumatoid arthritis in clinical settings. The implications of this paper: The self‐determination theory‐based, nurse‐led, physical activity programme can improve physical and psychosocial outcomes in postmenopausal women with rheumatoid arthritis.Importantly, this nurse‐led and theory‐based programme is expected to be applicable to postmenopausal women with rheumatoid arthritis in clinical settings, including both hospitals and communities.

Aim: This study aimed to examine a hypothetical model of physical activity (PA) and health outcomes related to sarcopenia in women with rheumatoid arthritis (RA) based on self‐determination theory. Design: Cross‐sectional study. Methods: This study included 214 women diagnosed with RA from the outpatient rheumatology department of a university‐affiliated hospital in South Korea. Data were collected from September 2019 to August 2020 through structured questionnaires and anthropometric measurements and analysed using path analysis to test the hypothesized model. The primary health outcomes were perceived health status and sarcopenia‐related health (thigh circumference, handgrip strength and sarcopenia risk). Results: The final model's fit indices were adequate. Physical activity was directly affected by motivation for PA, while depression, self‐efficacy for PA, health care provider's autonomy support and basic psychological needs satisfaction indirectly affected PA. Physical activity directly affected perceived health status and thigh circumference, while perceived sarcopenia risk and handgrip strength were directly affected by disease activity and age. Patient or Public Contribution: Patients were involved in a questionnaire‐based survey. [ABSTRACT FROM AUTHOR]

This study examined the psychometric properties of the Korean version of the Patient Knowledge Questionnaire-Osteoarthritis (PKQ-OA-K). A cross-sectional survey was conducted with 157 adults with osteoarthritis from the outpatient clinic at a university hospital in Korea. The overall correct answer rate for the PKQ-OA-K was 60.4%; notably, the drug therapy subscale had the lowest median score percentage (42.9%). For structural validity, exploratory factor analysis identified the PKQ-OA-K as two-dimensional, explaining 52.4% of the total variance. Confirmatory factor analysis showed that the two-factor model adequately fit the data. The PKQ-OA-K was positively correlated with education level (r = 0.24) and osteoarthritis outcomes (r = 0.17), thus verifying the hypotheses of construct validity. The intraclass correlation coefficient for test-retest reliability was 0.52; alpha was 0.44. The PKQ-OA-K has excellent validity but imperfect reliability for adults with osteoarthritis. This study recommends cautious use of the PKQ-OA-K to assess Korean patients' knowledge of osteoarthritis. [ABSTRACT FROM AUTHOR]

Aims and objectives: The effects of an individualised nutritional education and support programme on dietary habits, nutritional knowledge and nutritional status of 71 older adults living alone were examined. Background: Although a regular dietary meal plan is recommended for improving nutritional status of older adults living alone, little research is done in this field in Korea. Design: A pre‐ and post‐test controlled quasi‐experimental design was used at public health centres. Methods: The intervention group participated in an intensive nutritional education and support programme once a week for 8 weeks with dietary menus provided by home visiting nurses/dieticians; control group received usual care. Dietary habits and nutritional knowledge were assessed using structured questionnaires; nutritional intake status was analysed using Computer Aided Nutritional Analysis Program 5.0. Results: The mean age of participants was 77.6 years, and 81.7% of the participants were women. At 8 weeks, there were significant interactions of group by time for dietary habits, nutritional knowledge and selected nutritional status of protein, iron and vitamins of B2 and C. Changes over time in the mean score of dietary habits and nutritional knowledge were significantly improved in the intervention group compared to the control group. The percentages of normal nutrition intake of protein, iron and vitamins A and C in the intervention group were significantly higher than the control group at 8 weeks. Conclusions: Nutritional education and support programme positively impacted dietary habits, nutritional knowledge and selected nutritional status in older adults living alone, and we highlight the need for community‐based nutritional education and counselling programmes. Relevance to clinical practice: Older adults living alone in a community have relatively poor nutritional status and thus require tailored nutritional intervention according to objective nutritional analysis. It is necessary to link visiting nurses with dieticians in the community to manage effective nutritional programme continuously. [ABSTRACT FROM AUTHOR]

Aim The study purpose was to determine factors affecting aging cognitive function of 3,645 community-dwelling older adults in Korea. Methods The Hasegawa Dementia Scale assessed aging cognitive function, blood analyses and anthropometrics assessed cardio-metabolic risk factors, and the Geriatric Depression Scale Short Form Korean Version assessed depressive symptoms. Results Participants with poor aging cognitive function were more likely to be in the late age group (≥75 y) and currently smoking and have a medical history of stroke, high body mass index, and high level of depressive symptoms; they were also less likely to engage in regular meals and physical activities. Conclusion Regular meals and physical activities may be primary factors for clinical assessment to identify older adults at risk for aging cognitive function. With aging, depressive symptoms and other unhealthy lifestyle behaviours should be managed to prevent cognitive function disorders. [ABSTRACT FROM AUTHOR]

Aim To examine the mediating role of social support on the relationship of depressive symptoms to medication adherence and self-care activities in Korean adults. Background Recent evidence suggests that higher levels of social support are associated with improved medication adherence and self-care activities; however, the role of social support on the relationship of depressive symptoms to medication adherence and self-care activities is less well understood. Design A cross-sectional survey. Methods The data were collected from 311 Korean adults with type 2 diabetes who were taking hypoglycaemic agents in the period 2012-2013. Depressive symptoms, social support, medication adherence and self-care activities were assessed using structured questionnaires. Multiple regression analysis with adjustment for covariates and the Sobel test were used to examine the mediating effect of social support on the relationship of depressive symptoms to medication adherence and self-care activities. Results There were statistically significant differences by subgroups with and without depressive symptoms in social support, medication adherence and self-care activities of diet, physical activity and stress management. The Sobel test confirmed that social support mediated the effect of depressive symptoms on medication adherence and self-care activities of diet, physical activity and stress management. Conclusion The evidence from this study suggests that social support-enhancing interventions that also manage depressive symptoms may be more timely and effective than interventions that target depressive symptoms alone in promoting adherence to medication adherence and self-care activities in this population.

Objective To examine the psychometric properties of a structured self-reported 8-item Korean-version Morisky Medication Adherence Scale ( MMAS- K) among rural older adults with hypertension. Design Cross-sectional descriptive survey. Setting A rural community comprising three primary health care posts in Gangwon Province, South Korea. Participants Ninety-two older adults with hypertension who received treatment at primary health care posts. Main outcome measures Participants completed an 8-item MMAS- K questionnaire, and the community health practitioners manually measured blood pressure. Factor analysis and correlation coefficient for validity and the Kuder- Richardson alpha coefficient for reliability of the MMAS- K were used, while the association between medication adherence and blood pressure control was determined using Fisher's exact test. Results Internal consistency reliability was acceptable with a coefficient alpha of 0.71. The factor analysis of construct validity identified two dimensions of the 8-item MMAS- K, explaining 52.22% of the total variance. There was a high correlation between the 8-item MMAS- K and the original 4-item MMAS ( r = 0.874), indicating that these scales measure theoretically related constructs for convergent validity. There was a significant association between the 8-item MMAS- K score and blood pressure control ( P < 0.05), indicating that, for the known-groups validity, the controlled blood pressure group was more likely to have higher rate of medication adherence than the poor-control group. Conclusions The findings indicate a positive association between medication adherence and blood pressure control. The 8-item MMAS- K possesses adequate validity and reliability among rural older adults with hypertension. [ABSTRACT FROM AUTHOR]

Purpose: To examine the validity and reliability of the Chronic Disease Self-Efficacy Scale–Korean Version (CDSES-K) in 380 Korean adults with three chronic diseases: arthritis, diabetes, and hypertension. Methods: The Korean translated CDSES-K was back-translated to ensure translation equivalency. A methodological research design was used with exploratory factor analysis for validity and Cronbach’s alpha coefficients for reliability. Results: The factor analysis identified eight CDSES-K factors explaining 72.5% of the total variance. The internal consistency reliability for the total instrument was high with Cronbach’s alpha of .93. Conclusion: The results support the cross-cultural applicability of the concepts underlying the CDSES-K and the self-efficacy transcends across cultures. Implications: The CDSES-K can be used not only to assess self-efficacy in Koreans with chronic diseases but also to examine the potential function of self-efficacy in improvement of self-management behaviors and enhanced health status of people with chronic diseases in a variety of clinical settings.

The aims of the present systematic review were to identify currently available patient-reported outcome measures for diabetes self-care that have been psychometrically evaluated and to evaluate their measurement properties. A systematic literature review with a meta-analysis. A systematic literature search was conducted of the MEDLINE, EMBASE, and CINAHL databases. The updated COnsensus-based Standards for the selection of health Measurement INstruments (COSMIN) was applied using the following steps to evaluate the measurement properties of the diabetes self-care measures: (1) evaluating the methodological quality, (2) evaluating either quantitatively summarized or quantitatively pooled data against criteria for good measurement properties, and (3) the evaluating the quality of evidence by applying the modified Grading of Recommendations Assessment, Development, and Evaluation approach. Among 8434 articles yielded by the database search, 27 full-text articles that reported 34 studies of 13 different patient-reported outcome measures were included in this systematic review. The Diabetes Self-Management Instrument demonstrated the best content validity, with sufficient moderate-quality evidence for relevance, comprehensiveness, and comprehensibility. The Diabetes Self-Management Instrument exhibited sufficient moderate-quality evidence for structural validity and internal consistency, and sufficient high-quality evidence for convergent validity of hypothesis testing and sufficient low-quality evidence for reliability. The eight-item Summary of Diabetes Self-Care Activities–Revised was the most frequently investigated and shortest instrument with sufficient high-quality evidence for structural validity and internal consistency. However, the sufficient but very-low-quality comprehensiveness and the inconsistent very-low-quality comprehensibility for content validity, and the insufficient low-quality evidence for reliability must be considered when selecting this instrument. None of the identified diabetes self-care instruments appears to be universally superior to the others. The Diabetes Self-Management Instrument might be the best based on current evidence, but this requires further evaluation of the measurement of invariance across languages. The eight-item Summary of Diabetes Self-Care Activities–Revised is the shortest instrument, but current evidence with regards to its content validity and reliability needs to be considered before applying this instrument. Further studies are recommended to evaluate the reliability, measurement error, and responsiveness of the diabetes self-care measurements. [ABSTRACT FROM AUTHOR]
