Objectives: To examine (1) how visual green space quantity and quality affect depression among older adults; (2) whether and how the links may be mediated by perceived stress, physical activity, neighbourhood social cohesion, and air pollution (PM_2.5); and (3) whether there are differences in the mediation across visual green space quantity and quality.

Method: We used older adults samples (aged over 65) from the WHO Study on Global Ageing and Adult Health in Shanghai, China. Depression was quantified by two self-reported questions related to the diagnosis of depression and medications or other treatments for depression. Visual green space quantity and quality were calculated using street view images and machine learning methods (street view green space = SVG). Mediators included perceived stress, social cohesion, physical activity, and PM_2.5. Multilevel logistic and linear regression models were applied to understand the mediating roles of the above mediators in the link between visual green space quantity and quality and depression in older adults.

Results: SVG quantity and quality were negatively related to depression. Significant partial mediators for SVG quality were social cohesion and perceived stress. For SVG quantity, there was no evidence that any of the above mediators mediated the association.

Conclusion: Our results indicated that visual green space quantity and quality may be related to depression in older adults through different mechanisms.

Objectives: Support for people with dementia in their communities is neither robust nor consistent in the UK, often bolstered by third sector/grass-roots initiatives facing formidable challenges in sustaining long-term. The Get Real with Meeting Centres project explored factors involved in sustaining one such form of community-based support. This is the second of two linked articles outlining learning from this realist evaluation of Meeting Centres (MCs) for people with dementia and carers, which focusses on findings regarding their operational and strategic running.

Method: Semi-structured interviews and focus group discussions were conducted with 77 participants across three MC sites in England and Wales, including people living with dementia, informal carers, staff, volunteers, trustees, and supporting professionals/practitioners. Data were themed, then analysed using soft systems methodology and realist logic of analysis.

Results: Forty-two 'context-mechanism-outcome' statements were generated, explaining how background circumstances might trigger responses/processes to produce wanted or unwanted outcomes regarding three key areas for MC sustainability: External relationships and collaboration; Internal relationships and practices; and Finances and funding.

Conclusion: Collaboration is essential to sustaining community-based initiatives such as MCs, particularly between local community and regional level. MCs need to be vigilant in mitigating pressures that create 'mission drift', as targeting a gap in the care pathway and maintaining a person-centred ethos are central to MCs' appeal. Stable, ongoing funding is needed for stable, ongoing community dementia support. More formal recognition of the value of social model community-based initiatives, helped by improved data collection, would encourage more robust and consistent community dementia support.

Objectives: To explore patient and care partner experiences of receiving an amyloid scan result, with a focus on how clinician disclosure practices influenced patient and care partner emotional responses to the scan result and/or diagnosis.

Methods: Semi-structured interviews with 38 people with mild cognitive impairment or dementia and 62 care partners who experienced the disclosure of results from an amyloid PET scan as part of the CARE-IDEAS study. We used thematic analysis to analyze interview transcripts.

Results: We identified four aspects of the disclosure process that could influence patient and care partner emotional experiences of the scan result/diagnosis: (1) mode of delivery, (2) presence of a care partner, (3) clarity of the scan result explanation, and (4) discussion of post-scan treatment and support options.

Conclusions: Emotional experiences of an amyloid scan result can vary depending on how results are communicated. These findings support previous efforts to develop standard disclosure protocols. Scan results should be delivered in person with the care partner present. Clinicians should give a clear explanation of the result and its implications in an empathetic manner. Options for treatment and support should be discussed for all patients.

Objectives: The first aim of the study is to compare loneliness levels between widowed and non-widowed older adults. The second aim is to identify distinct loneliness patterns among widowed individuals and explore the impact of pre-spousal loss social support on loneliness during and after bereavement.

Method: Data from the Health and Retirement Study were utilized to compare loneliness levels between widowed (n = 137) and non-widowed (n = 2361) older adults (M_age = 69.01). T-tests and latent growth curve models were conducted to compare loneliness levels between the two groups. Growth mixture models were computed to identify distinct loneliness patterns among the widowed individuals. A multinomial logistic regression analysis was conducted to determine how pre-widowhood social support was associated with the obtained classes.

Results: The results revealed that widowed individuals reported significantly higher levels of loneliness at T2. Among widowed individuals, three distinct loneliness patterns were identified: Increased Loneliness (IL) group (n = 32); Low and Stable Loneliness (LSL) group (n = 88); and Decreased Loneliness (DL) group (n = 17). The IL and DL group were less likely to receive social support from spouse, children, and friends compared to the LSL group.

Conclusion: This study provides evidence of the protective effect of pre-widowhood social support on the psychological well-being of older adults after spousal loss.

Objectives: Hemoglobin (Hgb) is associated with cognitive function, with low and high levels of Hgb leading to impaired cerebral oxygenation and perfusion. Yet, current studies focused on understanding the association between Hgb and cognitive function without consideration for each cognitive domain. Thus, this study aims to identify and visualize potentially interactive associations between Hgb and specific cognitive domains among older adults.

Method: This is a secondary data analysis using Wave II data from the National Social Life, Health, and Aging Project (NSHAP) and included 1022 older adults aged between 65 and 85 years. The network structure of three different models was estimated to understand the association between specific cognitive domains and Hgb in a mixed graphical model using the R-package 'mgm'. Model 1 did not adjust for any covariates, Model 2 adjusted for age and gender, and Model 3 adjusted for all covariates.

Results: Among all cognitive domains, the visuospatial (edge weight = 0.06-0.10) and memory domains (0.04-0.07) were associated with Hgb in all three models Though not present in Model 3, the attention domain was associated with Hgb in Model 1 and Model 2 (0.08-0.11). In addition, the predictability of Hgb was the highest (8.1%) in Model 3.

Conclusion: Findings from this study suggest that cognition should be considered as a multidimensional construct, and its specific cognitive domain should be carefully assessed and managed in relation to Hgb among older adults.

Objectives: This study examined the mediating role of care partner burden on the relationship between patient clinical factors (i.e. cognition, physical function, and behavioral and psychological symptoms of dementia [BPSD]) and care partner mental health (i.e. anxiety and depression) among dementia care partners at hospital discharge.

Method: The sample consisted of 431 patient and care partner dyads enrolled in the Family centered Function-focused Care (Fam-FFC) study; ClinicalTrials.gov identifier NCT03046121. Mediation analyses were conducted to test the role of care partner burden on the associations between patient clinical factors, and care partner anxiety and depression.

Results: Mediation models demonstrated that care partner burden partially mediated the relationship between patient physical function and care partner anxiety and depression, as well as patient BPSD and care partner anxiety and depression.

Conclusion: Findings highlight the need for clinicians and service providers to implement comprehensive strategies that address both patient clinical factors (i.e. physical function and BPSD) and care partner burden, to optimize care partner mental health outcomes during post-hospital transition.

Objectives: A significant gap currently exists in the availability of reliable and scientifically rigorous measures for evaluating resilience among older Arabic-speaking populations. The primary objective of this study was to assess the psychometric properties of an Arabic adaptation of the 15-item Resilience Scale of Older Adults (RSOA) in a sample of Arabic-speaking Egyptian older adults.

Method: Using a cross-sectional design and a convenience sample of 539 Egyptian older adults, with 60.7% aged between 65 and 75 years (50.3% females), participants completed an online Google form-based anonymous questionnaire, including sociodemographic information, the RSOA, and the 10-item CD-RISC. To ensure accurate translation, the forward-backward translation method was employed. Confirmatory factor analysis (CFA) and gender invariance in the RSOA were analyzed. McDonald's ω and Cronbach's α were calculated to assess internal consistency.

Results: The results demonstrate that the Arabic RSOA and its subscales exhibit high internal consistency, with McDonald's ω and Cronbach's α values ranging from 0.83 to 0.93. CFA analysis revealed that the four-factor model fit of RSOA was acceptable. Measurement invariance was supported across genders. Furthermore, both genders exhibited no significant differences in all four RSOA dimensions. Convergent validity was supported by demonstrating that the four RSOA sub-scores and total scores correlated positively and significantly with the 10-item CD-RISC.

Conclusion: While further cross-cultural validation involving other Arab countries and communities is necessary, this study suggests that the Arabic RSOA may be used to measure resilience among broader Arabic-speaking older adults in clinical and research contexts.

Objectives: Social isolation and loneliness pose significant public health risks, especially among older adults experiencing age-related cognitive decline (ACD). This mixed methods feasibility study explored the potential of an online mindfulness-based dance/movement therapy (M-DMT) program to alleviate loneliness, enhance psychological well-being, and promote physical activity among older adults experiencing ACD during the COVID-19 pandemic.

Method: Sixteen participants engaged in a 12-week online group M-DMT program. Feasibility was assessed via enrollment and retention rates, attendance, adverse events, credibility/expectancy, participant perceptions, and satisfaction. Qualitative data were collected to capture participants' perspectives on the intervention's usefulness and perceived benefits. The intervention's preliminary impact on loneliness, depression, positive affect, psychological well-being, and physical activity was also examined.

Results: The study met all feasibility criteria, with 65% reporting post-intervention improvement. Significant reductions in loneliness and depression, along with enhanced positive affect and psychological well-being, were observed. Though physical activity increased, statistical significance was not achieved. Qualitative feedback highlighted improved social connectedness, overall quality of life, body awareness, kinematic strategy, and satisfaction with the program.

Conclusion: Online M-DMT holds promise in addressing well-being and loneliness challenges in older adults experiencing ACD. Further research is necessary to validate and expand upon these promising findings.

Objectives: Loneliness is associated with maladaptive cognitions, yet little is known about the association between loneliness and intrusive thinking during older adulthood. Links between loneliness and intrusive thoughts may be particularly strong among individuals with mild cognitive impairment (MCI), who may have greater difficulty regulating emotion and intrusive thoughts. In contrast, having close relationships (e.g. being married) may serve as a protective factor as marital status is associated with better overall well-being.

Method: Participants were 316 older adults (recruited from the Bronx, NY, as part of a larger study) without dementia at study intake (40% Black; 13% Hispanic, M_age = 77.45 years, 67% women) who completed ecological momentary assessments five times daily for 14 consecutive days (13,957 EMAs total). Multilevel modeling was used to examine the association between momentary loneliness and intrusive thoughts and whether MCI and marital status interacted to moderate this association.

Results: There was a significant three-way interaction (β = -0.17, p < 0.05), such that lagged momentary loneliness was positively associated with intrusive thoughts (3-4 h later) for those with MCI who were not married.

Conclusion: Findings suggest that among older adults with MCI, being married may be a protective factor and being unmarried may be a risk factor for experiencing loneliness and subsequent intrusive thoughts.

Objectives: Loneliness adversely affects the prognosis, treatment, and remission of late-life depression. However, no clear distinction of the cause or definition of loneliness was imposed in existing literatures, resulting in mixed findings of the effect of loneliness to late-life depression (LLD). The aim of this study was to explore the association between different facets of loneliness and risk factors of LLD, specifically, if age of onset in LLD possess a different clinical profile in the clinical group.

Method: 101 Chinese patients with depression and 81 healthy elderlies aged 60 or above were assessed on loneliness level, depressive symptoms, cognitive symptoms, physical condition, and motivational level. Univariate analyses were applied in exploring group differences in clinical profiles and multivariate regression to determine variables associated with subsets of loneliness.

Results: LLD patients reported more emotional loneliness but not social loneliness than healthy controls (p < 0.001). Emotional loneliness was the only significant predictor of suicidal ideation, particularly on patients with early-onset depression, explaining 26.8% of the effect (p < 0.001). Finally, the effect of medical comorbidity on depression severity was mediated by emotional loneliness(Z = 2.159, p = 0.031).

Conclusion: The current research highlights more attention should be placed on the age of onset and medical comorbidity in elderlies with depression. The distinction between emotional loneliness and social loneliness is better understood in the Asian population, reinforcing the importance of taking cultural influence into account when understanding psychological constructs.
