While previous studies have examined racial/ethnic or gender differences in SPA, few have adopted an intersectionality perspective that considers how multiple marginalized identities jointly shape these perceptions. This study examined positive and negative SPA across intersecting racial/ethnic and gender subgroups of older adults.Research design and methods: Data were drawn from three waves (2008/2010, 2012/2014, 2016/2018) of the Health and Retirement Study (HRS). Participants aged 65 and older who completed the Leave Behind Questionnaire were included (T1 n = 9,275; T2 n = 6,371; T3 n = 3,827). Random-effects panel regression models were used to assess differences in SPA across race/ethnicity × gender subgroups, adjusting for sociodemographic characteristics, physical and social functioning, perceived discrimination, and sense of control.Results: Compared to non-Hispanic White men, all racial/ethnic minority subgroups reported significantly more positive SPA. For negative SPA, non-Hispanic Black men and women reported significantly lower levels, while Hispanic men reported significantly higher levels. No significant differences in negative SPA were found for Hispanic women or non-Hispanic White women, relative to non-Hispanic White men.Discussion and implications: Distinct patterns in SPA across intersecting identities highlight the need for targeted, culturally informed interventions. Programs that address aging-related identity shifts-especially among Hispanic men and non-Hispanic White men-may reduce negative SPA and promote psychological resilience. Embedding intersectionality into intervention design is essential to advancing equity in aging and well-being.","PeriodicalId":51347,"journal":{"name":"Gerontologist","volume":" ","pages":""},"PeriodicalIF":3.2,"publicationDate":"2025-09-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145092941","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

As a community-based system, it allows participants to exchange services or goods using time as currency-where one hour of service equals one time credit. However, there is limited understanding of whether timebanking might crowd out other volunteering participation elsewhere, and whether it perpetuates or alleviates social inequality of access to volunteering.Research design and methods: This article presents findings from a quasi-experimental study on a timebanking program for adults aged 50 and above in Hong Kong, conducted between January 2021 and August 2022. The study involved 116 participants in the timebanking group and 114 in a comparison group. Both groups engaged in volunteer activities at local community centers, but only the timebanking group could exchange earned time credits for rewards.Results: After controlling for covariates, we found timebanking significantly increased within-program volunteering hours (T1: β = 0.56, p < 0.001; T2: β = 0.36, p = 0.003) without reducing other volunteering hours elsewhere. Effects were stronger among subgroups: adults aged 65 + (T1: β = 0.57, p = 0.021; T2: β = 0.63, p = 0.010), those with lower education (T1: β = 1.25, p = 0.001; T2: β = 1.24, p = 0.001), and individuals with multimorbidity (T1: β = 0.79, p = 0.013).Discussion and implications: Policymakers should integrate timebanking into community-based strategies to promote equity in late-life volunteering for healthy aging.","PeriodicalId":51347,"journal":{"name":"Gerontologist","volume":" ","pages":""},"PeriodicalIF":3.2,"publicationDate":"2025-09-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145092991","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Key recommendations include requiring a fraudulent participant detection plan in grant applications, training peer reviewers and research teams, and implementing regular data checks. We also discuss the importance of collaboration with Institutional Review Board representatives, funders, universities, and professional organizations who uphold scientific integrity of research accompanied by the dissemination of experiences to educate the scientific community.

The Multidimensional Fatalism Scale (MFS) indicated promising psychometric properties, but it was originally developed and validated using a college student sample. The present study aimed to validate the MFS for older adults and examined associations of multiple fatalism dimensions with health and well-being.Research design and methods: We analyzed data from 476 participants aged 65 + (whose mean age was 70.0 [SD = 4.4], female 62%) recruited through an online crowdsourcing platform, Prolific. We evaluated the MFS in dimensionality (conducting confirmatory factor analysis), internal consistency reliability, and convergent and discriminant validity. Additionally, we conducted multiple regressions examining associations of fatalism dimensions with depression, physical functioning, or purpose in life, controlling for covariates.Results: For our older adult sample, the MFS had psychometric properties comparable to the original validation, though its dimensionality was not optimal. The regression analyses showed associations of stronger beliefs in ineluctable destiny (ie, fate) and lower helplessness with lower depression; of stronger beliefs in luck with better physical functioning; of lower helplessness, higher internal locus of control, and weaker beliefs in luck with higher purpose in life.Discussion and implications: Our validation of the MFS was inconclusive, calling for more thorough investigations of this potentially useful measure in aging research. Our findings also showed positive implications of some fatalistic beliefs (e.g., ineluctable destiny), suggesting future research to address the complexity of fatalism relating to health and well-being for older adults.","PeriodicalId":51347,"journal":{"name":"Gerontologist","volume":" ","pages":""},"PeriodicalIF":3.2,"publicationDate":"2025-09-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145092934","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The Memory Impact Questionnaire (MIQ) is a 51-item measure that assesses the negative impact of memory changes on one's lifestyle activities, negative appraisals of the self due to memory changes, perceived negative appraisals from others due to memory changes, and coping approaches intended to compensate for memory changes. To improve the utility of this tool, we developed a short form version of the MIQ and investigated its psychometric properties.Research design and methods: First, we established a 27-item version of the MIQ based on re-analysis of a previously collected sample of 205 adults (Mage = 71.8, SDage = 8.7) using a newly developed statistical tool for shortening existing measures (the Optimization App for Selecting Item Subsets). Next, we examined the psychometric properties of the short-form MIQ among an independent sample of 673 middle-aged and older adults (Mage = 73.1, SDage = 7.6).Results: Our results revealed strong convergent (|rs| = 0.40-0.81) and discriminant validity (|r| = 0.19), test-retest reliability (ICC = 0.91), and internal consistency (α=0.88) of the short-form MIQ. Factor structure and model fit were investigated and confirmed via exploratory and confirmatory factor analyses. Robust measurement invariance was demonstrated across gender, age and level of education.Discussion and implications: Our findings demonstrate that the shortened MIQ retains the psychometric properties of the original scale while decreasing questionnaire length by ∼50%, thus improving its utility in both clinical and research settings.","PeriodicalId":51347,"journal":{"name":"Gerontologist","volume":" ","pages":""},"PeriodicalIF":3.2,"publicationDate":"2025-09-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145034672","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Gerontology needs to develop approaches for helping older people and their communities respond and share knowledge from those approaches. Based in the philosophy of pragmatism, we make a case for a 'melioristic gerontology' to focus gerontologists on those needs. After an introduction to pragmatism and its deep-rooted meliorism, we suggest several mega-trends-climate change, technological, and political economic-at the heart of our rationale for a melioristic gerontology. We then consider John Dewey's theory of social inquiry and Jane Addams' model of pragmatist praxis in communities. Both have inspired recent work to address community issues and citizens' engagement in those pragmatist-informed processes. We distill these contributions into essential traits of melioristic gerontology and identify key roles for melioristic gerontologists. Melioristic gerontology suggests how we can fulfill our responsibility for securing a better place in a world full of uncertainty by empowering older people and their communities to blunt the harmful effects of mega-trends now and in the future.","PeriodicalId":51347,"journal":{"name":"Gerontologist","volume":" ","pages":""},"PeriodicalIF":3.2,"publicationDate":"2025-09-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145034642","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A small but growing body of volunteer programs target people with mild cognitive impairment (MCI)-who are presumably at elevated risk for ADRD, but we know surprisingly little about who volunteers with MCI and how volunteering affects their subsequent cognitive changes. The current study sought to address these gaps.Research design and methods: We used longitudinal data from the Health and Retirement Study (2002-2018) and identified a pooled sample of 6,930 midlife and older adults (aged 50+) who met criteria for MCI based on their cognitive scores on the Telephone Interview for Cognitive Status (TICS). We tracked these participants' sociodemographic characteristics, volunteer activities, and cognitive scores in the subsequent 4 years.Results: A two-level logistic regression showed that among midlife and older adults with MCI, those who attained more years of education, had greater wealth, reported a history of volunteering, and had better self-rated health as well as fewer functional limitations were more likely to report volunteering in the presence of MCI. Volunteers with MCI-particularly those who continuously volunteered or initiated volunteering-exhibited more positive cognitive changes over time.Discussion and implications: This study highlights the importance of socioeconomic resources and health in predicting volunteering with MCI and reveals lasting cognitive benefits of volunteering as midlife and older adults adjust to their cognitive impairment.

This prospective observational aimed to detect, characterize, and validate potential LEs.Research design and methods: Data from longitudinal audiovisual observations of participants living with advanced dementia (N = 20) were coded to generate measures of verbal output/expressions and nonverbal communicative actions (e.g., coherence, eye gaze). Potential LEs underwent a structured multi-informant review for validation. We applied generalized estimating equations to compare features of validated LEs to a random 20% sample of participant data used to estimate baseline functioning. Data were fit to a homogeneous Poisson point process to estimate the number of observations needed to accurately estimate the prevalence of LEs.Results: Across 539 observations, nine validated LEs were evidenced by three participants (range 2-4). Shared significant differences across LEs included an increased rate of meaningful vocalizations, although heterogeneity in features of LE was observed.Discussion and implications: These findings represent the first prospectively documented and directly observed cases of LEs in advanced dementia. Features of LEs vary across individuals, but marked recovery of verbal communication abilities was a defining feature across all events. Lucid episodes occur infrequently, but these findings suggest that they may not be as rare as initially hypothesized.
