Validating interRAI Chinese self-reported carer needs (SCaN) assessment and predicting caregiving distress among informal Chinese caregivers of older adults.

BACKGROUND: This study aims to (1) determine the reliability and validity of the interRAI Chinese Self-reported Carer Needs (SCaN) assessment among informal Chinese caregivers of older adults, (2) identify predictors of caregiving distress in Asian regions with long-standing Confucian values of filial piety and family responsibility. METHODS: This cross-sectional study recruited 531 informal Chinese caregivers of older adults in Hong Kong, Shanghai, Taiwan, and Singapore. The scale reliability was examined using Cronbach's alphas (α) and McDonald's omega coefficient (ω). The concurrent validity and discriminant validity were assessed using Spearman rank correlations (rho). To examine the predictors of caregiving distress among informal caregivers of older adults, we employed hierarchical linear regression analyses informed by the Model of Carer Stress and Burden and categorized the predictors into six domains. RESULTS: Results revealed good internal consistency reliability (α = 0.83-0.96) and concurrent validity (rho = 0.45-0.74) of the interRAI Chinese SCaN assessment. Hierarchical linear regression analysis revealed that entering the background factors, primary stressors, secondary stressors, appraisal, and exacerbating factors all significantly enhanced the model's predictability, indicating that the source of caregiving distress is multidimensional. In the full model, caregivers with longer informal care time, lack of support from family and friends, have unmet needs, experience role overload, have sleep problems, and low IADL functioning are at a higher risk of caregiving distress. CONCLUSIONS: The interRAI Chinese SCaN Assessment was found to be a reliable and valid tool among the Chinese informal caregivers of older adults. It would be useful for determining family caregivers' strengths, needs, and challenges, and tailoring interventions that address the potentially modifiable factors associated with caregiving distress and maximize support. Healthcare providers working in home and community settings should be aware of the early identification of caregiving distress and routine assessment of their needs and empower them to continue taking care of their needs and providing adequate care to the care recipient.

Facilitators and barriers to codesigning social robots with older adults with dementia: a scoping review protocol.

INTRODUCTION: Social robots including telepresence robots have emerged as potential support in dementia care. However, the effectiveness of these robots hinges significantly on their design and utility. These elements are often best understood by their end-users. Codesign involves collaborating directly with the end-users of a product during its development process. Engaging people with dementia in the design of social robots ensures that the products cater to their unique requirements, preferences, challenges, and needs. The objective of this scoping review is to understand the facilitators, barriers, and strategies in codesigning social robots with older adults with dementia. METHODS AND ANALYSIS: The scoping review will follow the Joanna Briggs Institute scoping review methodology and will be conducted from November 2023 to April 2024. The steps of search strategy will involve identifying keywords and index terms from CINAHL and PubMed, completing search using identified keywords and index terms across selected databases (Medline, CINAHL, PubMed, AgeLine, Web of Science, PsycINFO, Scopus, IEEE, and Google Scholar), and hand-searching the reference lists from chosen literature for additional literature. The grey literature will be searched using Google. Three research assistants will screen the titles and abstracts independently by referring to the inclusion criteria. Three researchers will independently assess the full text of literature following to the inclusion criteria. The data will be presented in a table with narratives that answers the questions of the scoping review. ETHICS AND DISSEMINATION: This scoping review does not require ethics approval because it collects data from publicly available resources. The findings will offer insights to inform future research and development of robots through collaboration with older people with dementia. In addition, the scoping review results will be disseminated through conference presentations and an open-access publication in a peer-reviewed journal.

From Skin Movement to Wearable Robotics: The Case of Robotic Gloves.

Previous research on wearable robotics focused on developing actuation mechanisms while overlooking influences of skin movement. During finger flexion, skins on the opisthenar and finger back are stretched. Impeding such skin movement will obstruct normal finger motions. In this research, a statistical study on skin movement is proposed and conducted to quantify skin movement on human hands. Results of 30 subjects (15 men and 15 women) reveal that skin at the finger back extends by an average of 29.3 ± 7.2% in fist clenching. Based on this study, design guidelines for robotic gloves are proposed, and nominal strain values at different hand regions are tabulated for references in robotic glove design. To explore the influence of skin movement on wearable robotics, an elastomer-constrained flat tube actuator is proposed based on which two prototype robotic gloves are developed: one with an ergonomic strap interface that has small constraint to skin motion, and the other based on the commonly used fabric glove that is supposed to have large constraint to skin motion. With the same power input to the robotic gloves, the strap-based design achieves a finger motion range of 2.5 times and a gripping force of 4.3 times that of the conventional fabric glove.

Randomized controlled trials on promoting self-care behaviors among informal caregivers of older patients: a systematic review and meta-analysis.

BACKGROUND: Informal caregivers of older patients often neglect their self-care, despite the mental and physical health effects of caregiving. Randomized controlled trials (RCTs) on self-care interventions for informal caregivers are lacking, making it difficult to determine effective strategies. This systematic review explored the definition and categories of self-care RCTs for informal caregivers and a meta-analysis was conducted to determine the effectiveness of these interventions. METHODS: Seven databases (Scopus, Web of Science, MEDLINE, PubMed, ProQuest, CINAHL, and Embase) were searched for articles in English reporting on self-care intervention outcomes for informal caregivers of patients aged 60 years or older. Standardized mean differences (SMD) with 95% confidence intervals (CI) were calculated using a random-effects model. Subgroup, sensitivity, and publication bias analyses were conducted. RESULTS: Eighteen studies were included in the systematic review, of which fifteen studies were included in the meta-analysis. RCTs lacked a clear definition of self-care, mainly focused on promoting physical and mental health and individual capacity, and neglected disease prevention. The interventions focused on self-management for health and individual agency, with less attention on health literacy, decision-making capacity, self-monitoring for health status, and linkage to the health system. Meta-analysis results showed that RCTs had a small effect on reducing anxiety (SMD = -0.142, 95% CI [-0.302, 0.017], p = .081) but a significant effect on reducing depression (SMD = -0.214, 95% CI [-0.353, -0.076], p = .002). Country and type of caregiver significantly contributed to the effect of reducing caregivers' depression in subgroup analysis. CONCLUSIONS: Studies on caregiver-centered self-care interventions are limited, resulting in a lack of a clear definition and comprehensive intervention. RCTs indicated a small effect on informal caregivers' mental health, and interventions should consider both mental and physical health. More evidence is needed on the effectiveness of self-care interventions for informal caregivers' anxiety and physical health.

Insomnia Symptom Trajectory of Spouse Caregivers of Older Adults with Functional Limitations.

OBJECTIVES: This study examined the long-term impact of spouse caregiving on insomnia symptoms, compared to propensity-score matched non-caregivers. METHODS: Health and Retirement Study data between 2006 and 2018 were used. Caregivers (n = 403) were respondents (aged 50+) who assisted their heterosexual spouses in performing (instrumental) activities of daily living at baseline. Non-caregivers were matched using a propensity score matching procedure based on baseline characteristics. Insomnia symptoms were measured every 4 years for both groups. Poisson mixed-effect models estimated the association between caregiver status and insomnia symptoms. RESULTS: Compared to matched non-caregivers, caregivers had similar severity of insomnia symptoms at baseline (ßcaregiver = 0.018, 95% CI = -0.089, 0.124) and reported a similar yearly change rate (ßcaregiver×time = -0.008, 95% CI = -0.017, 0.001). No moderation effects of care-recipients' dementia status and social support were significant. CONCLUSIONS: In this study sample, there is no evidence that spouse caregivers, specifically those who performed light duties, experience more severe insomnia symptoms than non-caregivers. CLINICAL IMPLICATIONS: Spouse caregiving, especially in a light-duty capacity, may not be detrimental to the caregivers' sleep health. More data are needed regarding insomnia in spouse caregivers with heavy duties of care to fully assess the health impact of the caregiving experience.

Staff Turnover Intention at Long-Term Care Facilities: Implications of Resident Aggression, Burnout, and Fatigue.

OBJECTIVES: Staff shortages and the high turnover rate of nursing assistants pose great challenges to long-term care. This study examined the effects of aggression from residents of long-term care facilities, burnout, and fatigue on staff turnover intention. The findings will help managers to devise effective measures to retain their staff. DESIGN: Cross-sectional descriptive study design. SETTING AND PARTICIPANTS: A total of 800 nursing assistants were recruited from 70 long-term care facilities using convenience sampling. METHODS: The participants were individually interviewed and provided information about their turnover intention, resident aggression witnessed and experienced, self-efficacy, neuroticism, burnout, fatigue, and personal and facility characteristics. RESULTS: Hierarchical multiple regression analysis revealed that the size and organizational practices of long-term care facilities were not associated with staff turnover intention. Staff who spent less time in the industry reported witnessing resident-to-resident aggression, experienced resident-to-staff aggression, reported high levels of burnout, had acute or chronic fatigue, and had low levels of inter-shift recovery were more likely than others to report a high turnover intention. CONCLUSIONS AND IMPLICATIONS: Staff turnover poses great challenges to staff, residents, and organizations. This study identified important factors that may help support staff in long-term care facilities. Specific measures, such as person-centered care to diminish resident aggression by addressing residents' unmet needs, work-directed programs to mitigate burnout and improve staff mental health, and flexible schedules to prevent fatigue should also be advocated to prevent staff turnover.

Quality of life in sarcopenia measured with the SarQoL questionnaire: A meta-analysis of individual patient data.

Age-related sarcopenia, resulting from a gradual loss in skeletal muscle mass and strength, is pivotal to the increased prevalence of functional limitation among the older adult community. The purpose of this meta-analysis of individual patient data is to investigate the difference in health-related quality of life between sarcopenic individuals and those without the condition using the Sarcopenia Quality of Life (SarQoL) questionnaire. A protocol was published on PROSPERO. Multiple databases and the grey literature were searched until March 2023 for studies reporting quality of life assessed with the SarQoL for patients with and without sarcopenia. Two researchers conducted the systematic review independently. A two-stage meta-analysis was performed. First, crude (mean difference) and adjusted (beta coefficient) effect sizes were calculated within each database; then, a random effect meta-analysis was applied to pool them. Heterogeneity was measured using the Q-test and I2 value. Subgroup analyses were performed to investigate the source of potential heterogeneity. The strength of evidence of this association was assessed using GRADE. From the 413 studies identified, 32 were eventually included, of which 10 were unpublished data studies. Sarcopenic participants displayed significantly reduced health-related quality of life compared with non-sarcopenic individuals (mean difference = -12.32; 95 % CI = [-15.27; -9.37]). The model revealed significant heterogeneity. Subgroup analyses revealed a substantial impact of regions, clinical settings, and diagnostic criteria on the difference in health-related quality of life between sarcopenic and non-sarcopenic individuals. The level of evidence was moderate. This meta-analysis of individual patient data suggested that sarcopenia is associated with lower health-related quality of life measured with SarQoL.

The association of technology acceptance and physical activity on frailty in older adults during the COVID-19 pandemic period.

BACKGROUND: Physical activity was known to be the protective factor against frailty. Technology acceptance is associated with behavioural intention to technology usage. Technology has been effective in promoting healthy behaviour of physical activity. The purposes of this study were to examine the association between physical activity and technology acceptance with frailty and examine the moderation effect of technology acceptance on physical activity and frailty. We hypothesize that 1) physical activity and technology acceptance are associated with frailty, and 2) technology acceptance moderates the association of physical activity with frailty. METHODS: This study employed a cross-sectional design and was conducted in the community settings of Hong Kong in 2021. Eligible participants were old people aged ≥60 and were community-dwelling. Key variables included physical activity measured by Rapid Assessment of Physical Activity (RAPA), social network measured by Lubben Social Network Scale-Six items (LSNS-6); depressive symptoms measured by Patient Health Questionnaire-Nine items (PHQ-9), technology acceptance measured by Senior Technology Acceptance Model-14 items (STAM-14) and frailty measured by Fatigue, Resistance, Ambulation, Illnesses, & Loss of Weight scale (FRAIL). Ordinal logistic regression was employed to test the hypotheses. The moderation effect was examined by introducing an interaction term formed by the multiplication of an independent variable (i.e., physical activity) and a moderating variable (i.e., technology acceptance). RESULTS: This study recruited 380 eligible participants with a mean age of 66.5 years. Technology acceptance (Beta = - 0.031, p < 0.001, Pseudo-R2 = 0.087) and physical activity (Beta = - 0.182, p = 0.003, Pseudo-R2 = 0.027) were associated with frailty in the unadjusted models. Technology acceptance (Beta = - 0.066, p < 0.001) and physical activity (Beta = - 1.192, p < 0.001) were also associated with frailty in the fully adjusted model (Pseudo-R2 = 0.352). Interaction term formed by the multiplication of technology acceptance and physical activity (Beta = 0.012, p = 0.001) was associated with frailty. Physical activity was significantly associated with frailty in the lower technology acceptance subgroup (Beta = - 0.313, p = 0.002) in the subgroup analysis. However, in the subgroup of higher technology acceptance, the association of physical activity (Beta = 0.104, p = 408) on frailty became positive but not significant. CONCLUSIONS: This study showed that physical activity and technology acceptance were associated with frailty, and technology acceptance moderated the association of physical activity with frailty. This study recommends engaging older adults in physical activity to combat frailty preferentially in those with a lower level of technology acceptance.

Caregiving Strain Mediates the Relationship Between Terminally Ill Patient's Physical Symptoms and Their Family Caregivers' Wellbeing: A Multicentered Longitudinal Study.

Objectives: Research considered patient outcomes primarily over caregivers in end-of-life care settings. The importance of family caregivers (FCs) in end-of-life care draws growing awareness, evidenced by an increasing number of evaluations of caregiver-targeted interventions. Little is known of FCs' collateral benefits in patient-oriented home-based end-of-life care. The study aims to investigate FC outcomes and change mechanisms in patient-oriented care. Methods: A pre-post-test study. We recruited FCs whose patients with a life expectancy ≤ 6 months enrolled in home-based end-of-life care provided by service organizations in Hong Kong. Patients' symptoms, dimensions of caregiving strain (ie, perception of caregiving, empathetic strain, adjustment demands), and aspects of FCs' wellbeing (ie, perceived health, positive mood, life satisfaction, spiritual well-being) were measured at baseline (T0) and 3 months later (T1). Results: Of the 345 FCs at T0, 113 provided T1 measures. Three months after the service commenced, FCs' caregiving strain significantly reduced, and their positive mood improved. Alleviation of the patient's physical symptoms predicted FC better outcomes, including the perception of caregiving, empathetic strain, and wellbeing. Changes in perception of caregiving mediated the effects of changes in patients' physical symptoms on FCs' changes in life satisfaction and spiritual wellbeing. Changes in empathetic strain mediated the changes between patient's physical symptoms and FCs' positive mood. Conclusions: Collateral benefits of patient-oriented home-based end-of-life care were encouraging for FCs. Patient's physical symptom management matters to FCs' caregiving strain and wellbeing. The active ingredients modifying FCs' perception of caregiving and addressing empathetic strain may amplify their benefits in wellbeing.

Prevalence and predictors of depressive symptoms among caregivers of patients with epilepsy in Hong Kong.

STUDY AIM: To estimate the prevalence of high caregiving burden and depressive symptoms among caregivers (CG) of patients with epilepsy (PWEs) in Hong Kong and identify risk and protective factors for both outcomes after the Model of Stress and Carer Burden (MSCB). METHODS: This cross-sectional study recruited participants from local epilepsy clinics to complete a 15-minute survey on a tablet. Caregiving burden (CB) was assessed using the 4-item Zarit Caregiver Burden Interview. Depressive symptoms were assessed using the 2-item Patient Health Questionnaire. Family functioning was assessed using the Short-Form Family Assessment Device General Functioning Subscale. Sociodemographic data of the caregivers and clinical data of the PWE they cared for were described. Hierarchical logistic regression models were used to analyze the factors associated with the outcomes. RESULTS: A hundred and fifty-one CGs of PWEs were recruited for this study. The prevalence of high caregiving burden (ZBI-4 > 7) for CGs of PWEs was 58.9% (n = 89), whereas the prevalence of high depressive symptoms (PHQ2 > 2) was 23.8% (n = 36). Hierarchical logistic regression analysis revealed that entering patient characteristics and care situations did not enhance the model's predictability. In the full model, a high perceived CB was a risk factor for elevated depressive symptoms. Good physical health protects against depressive symptoms. CONCLUSIONS: Among caregivers of PWE in Hong Kong, a high perceived caregiving burden was a risk factor for elevated depressive symptoms; however, the clinical characteristics of the PWEs were not. Self-reported physical health is a protective factor against increased depressive symptoms.

Technology Acceptance of a Social Robot (LOVOT) Among Single Older Adults in Hong Kong and Singapore: Protocol for a Multimethod Study.

BACKGROUND: Given the rapidly aging nature of our global population, policy makers around the world are now emphatically promoting active aging. To address the psychosocial needs of older persons and support active aging, researchers are exploring the use of assistive technologies, specifically social robots as companions. However, there is limited evidence on the efficacy of social robots in promoting active aging for older people in the Hong Kong and Singapore contexts. OBJECTIVE: This study presents the protocol of a study that investigates the acceptance and quality of interaction between a Japanese social robot, LOVOT, and single older adults in Hong Kong and Singapore. METHODS: We used a baseline assessment to measure the primary outcome, participants' acceptance of technology, and a sense of loneliness, namely, the participants' differences in responses to LOVOT before and following their interaction with the social robot in this multimethod study design. The baseline assessment consisted of the Qualtrics survey, which measures senior technology acceptance, loneliness, older people's quality of life, subjective happiness, cultural values, willingness to pay, and demographic characteristics, along with the LOVOT's sociability and system usability. In the study, participants interacted with LOVOT in 3 sessions before being surveyed to measure the older people's acceptance and attitudes toward LOVOT. A pre-social robot intervention also occurred in the first session. The study was conducted in both Hong Kong and Singapore. A total of 15 single older adults (ie, individuals who live alone) from Hong Kong and another 15 from Singapore were recruited. Participants were 60-75 years of age, lived by themselves, and had no known cognitive or mental issues. RESULTS: The study began recruiting in March 2022, and recruitment was completed at the end of October 2022. Data collection and data set construction were completed at the end of January 2023. Analysis of the data is currently being conducted, and we plan to publish the results by mid-2023. CONCLUSIONS: At an individual level, the study will clarify if LOVOT influences single older adults' psychosocial well-being by reducing their loneliness. At a community level, the study's findings will illustrate whether LOVOT can provide increased social connectedness while decreasing individual loneliness. Last, this study's conclusions can inform policy makers to provide social robots to older people to improve their quality of life. Findings can also inform gerontechnology developers on which aspects and cultural considerations to take into account for future inventions.

GATEKEEPER's Strategy for the Multinational Large-Scale Piloting of an eHealth Platform: Tutorial on How to Identify Relevant Settings and Use Cases.

BACKGROUND: The World Health Organization's strategy toward healthy aging fosters person-centered integrated care sustained by eHealth systems. However, there is a need for standardized frameworks or platforms accommodating and interconnecting multiple of these systems while ensuring secure, relevant, fair, trust-based data sharing and use. The H2020 project GATEKEEPER aims to implement and test an open-source, European, standard-based, interoperable, and secure framework serving broad populations of aging citizens with heterogeneous health needs. OBJECTIVE: We aim to describe the rationale for the selection of an optimal group of settings for the multinational large-scale piloting of the GATEKEEPER platform. METHODS: The selection of implementation sites and reference use cases (RUCs) was based on the adoption of a double stratification pyramid reflecting the overall health of target populations and the intensity of proposed interventions; the identification of a principles guiding implementation site selection; and the elaboration of guidelines for RUC selection, ensuring clinical relevance and scientific excellence while covering the whole spectrum of citizen complexities and intervention intensities. RESULTS: Seven European countries were selected, covering Europe's geographical and socioeconomic heterogeneity: Cyprus, Germany, Greece, Italy, Poland, Spain, and the United Kingdom. These were complemented by the following 3 Asian pilots: Hong Kong, Singapore, and Taiwan. Implementation sites consisted of local ecosystems, including health care organizations and partners from industry, civil society, academia, and government, prioritizing the highly rated European Innovation Partnership on Active and Healthy Aging reference sites. RUCs covered the whole spectrum of chronic diseases, citizen complexities, and intervention intensities while privileging clinical relevance and scientific rigor. These included lifestyle-related early detection and interventions, using artificial intelligence-based digital coaches to promote healthy lifestyle and delay the onset or worsening of chronic diseases in healthy citizens; chronic obstructive pulmonary disease and heart failure decompensations management, proposing integrated care management based on advanced wearable monitoring and machine learning (ML) to predict decompensations; management of glycemic status in diabetes mellitus, based on beat to beat monitoring and short-term ML-based prediction of glycemic dynamics; treatment decision support systems for Parkinson disease, continuously monitoring motor and nonmotor complications to trigger enhanced treatment strategies; primary and secondary stroke prevention, using a coaching app and educational simulations with virtual and augmented reality; management of multimorbid older patients or patients with cancer, exploring novel chronic care models based on digital coaching, and advanced monitoring and ML; high blood pressure management, with ML-based predictions based on different intensities of monitoring through self-managed apps; and COVID-19 management, with integrated management tools limiting physical contact among actors. CONCLUSIONS: This paper provides a methodology for selecting adequate settings for the large-scale piloting of eHealth frameworks and exemplifies with the decisions taken in GATEKEEPER the current views of the WHO and European Commission while moving forward toward a European Data Space.

Typology of family caregivers of older persons: A latent profile analysis using elder mistreatment risk and protective factors.

This study sought to identify subpopulations of caregivers of older persons based on their profiles of individual characteristics and caregiving contexts and aimed at examining the associations between caregiver profiles and elder mistreatment. A convenient sample of 600 adult caregivers of community-dwelling older people in Hong Kong participated. Results of latent profile analysis support a typology of 3 distinctive caregiver profiles: (a) non-vulnerable caregivers; (b) isolated, vulnerable caregivers; and (c) traumatized, vulnerable caregivers. Isolated and traumatized caregivers reported greater risk factors related to elder mistreatment: They had higher levels of caregiver stress and burden, lower levels of social support and resilience, greater neurotic personality orientation and problematic gambling behavior, and more severe childhood traumatic experiences. The two groups also display significantly higher level of abusive behaviors than non-vulnerable caregivers.

Unmet needs and depression among spousal caregivers: the mediating role of marital satisfaction.

OBJECTIVES: Previous research has identified that unmet needs are associated with adverse mental health outcomes in older adults. However, the unmet needs of older adults' spousal caregivers are unknown. The present study examined the association between unmet needs and depression among spousal caregivers, and whether marital satisfaction mediated this association. METHODS: We included 1,856 participants who provided care to their spouses with difficulties in activities of daily living (ADL) and instrumental activities of daily living (IADL) from the 2018 China Health and Retirement Longitudinal Survey. Unmet needs of spousal caregivers were assessed as the total number of ADL/IADL tasks with which respondents had unmet needs. Path models were conducted to evaluate the associations between unmet needs, marital satisfaction, and depression. Subgroup analyses by sex were conducted to examine the sex differences regarding the associations. RESULTS: Spousal caregivers with more unmet ADL/IADL needs reported higher levels of depression (p < 0.001). Additionally, for wife caregivers, unmet ADL/IADL needs were associated with lower marital satisfaction, and lower marital satisfaction was associated with higher degrees of depression, indicating that marital satisfaction partially mediated the association between unmet needs and depression (p < 0.01). However, marital satisfaction did not mediate the association between unmet needs and depression among husband caregivers. CONCLUSIONS: The mediating effect of marital satisfaction on the association between unmet needs and depression only existed in wife caregivers. Social services should be provided to meet the needs of caregivers with ADL/IADL difficulties, and interventions should be implemented to promote the marital satisfaction of wife caregivers.

Co-Reasoning With the Significant Other(s): How Childless Older Adults in Rural China Make Residential Decisions.

Applying the concept of residential co-reasoning, this research explored the role of the next of kin in the residential decision-making of childless older adults in rural China. We examined research questions regarding who, if anyone, had been the significant other(s) during the residential decision-making, and how they conducted the co-reasoning process. A constructivist grounded theory approach was applied, with 27 childless older adults being interviewed. We found that participants tended to choose to age in place if they had a continuous, reliable, and trustworthy relationship with certain members of next of kin, which they referred to as "I have someone at home." Acquiring care from kin was an ongoing negotiation process. Participants applied three types of negotiations: exchanging properties for care from kin; maintaining relational intimacy with kin; and counting on the filial obligation of kin. Otherwise, if care from kin was unavailable, participants tended to relocate to rural institutions.

Caregivers' depressive symptom trajectories and risk of cognitive impairment among older adults with functional limitations: A prospective cohort study.

OBJECTIVES: Caregiver (CG)'s depression is common and its prevalence is rising. The relationship of CG depression with care recipients (CR)'s subsequent cognitive impairment remains unclear. This study examines the association of CG depressive symptoms trajectories with 6-year cognitive impairment risk among care recipients (CR) who are older adults with functional limitations. METHODS: Retrospective analysis of prospectively collected data cohorts from 2010 to 2016. The sample included 810 community-dwelling older adults aged ≥75 years, dementia free at baseline, with their primary caregiver dyads. CG's depressive symptoms were measured using the Center for Epidemiologic Studies Depression Scale. The main outcomes were incident mild, moderate, and severe cognitive impairment of CRs measured using Short Portable Mental Status Questionnaire. Group-based trajectory modeling identified three CG depressive symptom trajectory groups. Competing risks regression analysis modeled the hazards as a function of CG depressive symptom trajectories. RESULTS: Of 810 CRs, 3% developed severe cognitive impairment, 21% had moderate cognitive impairment, and 37% had mild cognitive impairment. Only CG's "Increasing" trajectory group predicted increased risk of CR's mild and moderate cognitive impairment relative to "persistently low" group (subhazard ratio [SHR] = 1.52, 95% confidence interval [CI], p < 0.05; SHR = 1.87, 95% CI, p < 0.05, respectively). CONCLUSIONS AND IMPLICATIONS: Finding highlight the intricate and non-linear association between CG depressive trajectory and CR cognitive impairment. This evidence can be used to enlighten policymakers and health providers about the need for risk stratification screening for CG mental health and early treatment for CG depression to prevent or delay CR's cognitive impairment.

Influence of spousal caregiving and living arrangement on depression among husband caregivers in rural China.

OBJECTIVES: With sociodemographic changes, men are increasingly taking responsibility for spousal caregiving. Previous studies have described gender differences in the psychological outcomes of caregiving; however, few have focused exclusively on husband caregivers. This study investigates the influence of starting spousal caregiving on the psychological well-being of older husbands in rural areas and examines whether living arrangements can moderate this relationship. METHODS: A total of 1,167 baseline non-caregiver husbands aged 60 and above in rural areas were taken from the 2011-2015 China Health and Retirement Longitudinal Study (CHARLS). The generalized estimating equation (GEE) was employed to examine the effects of spousal caregiving transitions and living arrangement changes on depressive symptoms over four years. RESULTS: Compared with rural husbands who remained non-caregivers, those transitioning into activities of daily living (ADL) caregiving reported higher depressive symptoms at follow-up (B = 1.67, p < 0.05). Moreover, the increase in depressive symptoms when transitioning into ADL caregiving was significantly lower among participants who changed from living with spouse alone to living with spouse and other family members together (B = - 5.37, p < 0.05). CONCLUSION: There was an association between transitioning into ADL caregiving and an elevated level of depression over four years among older husbands, which could be alleviated by living with family members. Co-residence with family members could serve as a natural support resource, buffering adverse mental health outcomes when older husbands start a demanding caregiving role.

Perceptions of neighborhood environment and loneliness among older Chinese adults: the mediator role of cognitive and structural social capital.

OBJECTIVE: This study aimed to examine the mediating role of social capital in the association between perceived physical neighborhood environment and loneliness among older adults in urban China. METHOD: Data were derived from face-to-face interviews with people (n = 472) aged 60 or older in urban communities of Shanghai, China, in 2020. Loneliness was measured by the 6-item De Jong Gierveld Scale. A multiple mediator model was adopted to examine the research hypotheses. RESULTS: Cognitive social capital played a full mediation role in the association between perceived community health care (ß = -.061, p < .05), safety (ß = -.168, p < .001), recreational services (ß = -.058, p < .05), and loneliness. Structural social capital was associated with loneliness (ß = -.102, p < .05), whereas its mediator effect was not significant. Perceived transportation convenience had neither a direct nor an indirect effect on loneliness among older adults. CONCLUSION: Findings indicate that older adults' perceptions of healthcare services, safety, and recreational resources could help alleviate their loneliness via fostering cognitive social capital. Interventions improving older adults' perceptions of community health care, safety, and recreation, and their social capital level could help reduce the prevalence of loneliness.

Multidisciplinary collaboration on exoskeleton development adopting user-centered design: a systematic integrative review.

Purpose: The world population is ageing, along with an increasing possibility of functional limitations that affect independent living. Assistive technologies such as exoskeletons for rehabilitative purposes and daily activities assistance maintaining the independence of people with disabilities, especially older adults who wish to ageing-in-place. The purpose of this systematic integrative review was threefold: to explore the development team compositions and involvement, to understand the recruitment and engagement of stakeholders, and to synthesise reported or anticipated consequences of multidisciplinary collaboration.Methods: Databases searched included PubMed, CINAHL Plus, PsycINFO, Web of Science, Scopus, and IEEE Xplore. A total of 34 studies that reported the development of exoskeleton adopting user-centered design (UCD) method in healthcare or community settings that were published in English from 2000 to July 2022 were included.Results: Three major trends emerged from the analysis of included studies. First, there is a need to redefine multidisciplinary collaboration, from within-discipline collaboration to cross-discipline collaboration. Second, the level of engagement of stakeholders during the exoskeleton development remained low. Third, there was no standardised measurement to quantify knowledge production currently.Conclusion: As suggested by the synthesised results in this review, exoskeleton development has been increasing to improve the functioning of people with disabilities. Exoskeleton development often required expertise from different disciplines and the involvement of stakeholders to increase acceptance, thus we propose the Multidisciplinary Collaboration Appraisal Tool to assess multidisciplinary collaboration using the UCD approach. Future research is required to understand the effectiveness of multidisciplinary collaboration on exoskeleton development using the UCD approach.IMPLICATIONS FOR REHABILITATIONGlobal trend of population ageing causes a higher risk of disability in older adults who require rehabilitation and assistance in daily living.Assistive technologies such as exoskeletons have the potential to contribute to rehabilitation training and daily activity assistance demand closer multidisciplinary collaboration.A Multidisciplinary Collaboration Appraisal Tool using user-centered design approach (MCAT) is proposed to understand the effectiveness as well as limitations and barriers associated with multidisciplinary collaboration in developing exoskeletons.
