Aims Although many studies have examined the predictors of medication adherence (MA), further empirical research is required to clarify the best model for predicting MA for older adults with heart failure (HF). Thus, we hypothesized a model in which information (knowledge), motivation (social support and depressive symptoms), and behavioural skills (barriers to self-efficacy) would be associated with MA in patients with HF. Methods and results Using a cross-sectional survey, 153 adults aged ≥ 65 years taking medication for HF were recruited from a university hospital in Korea. Data were collected based on the information–motivation–behavioural skills (IMB) model constructs and MA. In the hypothesized path model, self-efficacy was directly related to MA (β = −0.335, P = 0.006), whereas social support was indirectly related to MA through self-efficacy (β = −0.078, P = 0.027). Depressive symptoms were directly related to MA (β = 0.359, P = 0.004) and indirectly related to MA through self-efficacy (β = 0.141, P = 0.004). The hypothesized MA model showed a good fit for the data. Knowledge, social support, and depressive symptoms accounted for 44.3% of the variance in self-efficacy (P = 0.004). Left ventricular ejection fraction, knowledge, social support, depressive symptoms, and self-efficacy explained 64.4% of the variance in MA (P = 0.004). Conclusion These results confirmed the IMB model's suitability for predicting MA in older adults with HF. These findings may guide and inform intervention programmes designed to alleviate depressive symptoms in older adults with HF and enhance their HF knowledge, social support, and self-efficacy, with the ultimate goal of improving their MA.

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]

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.
