When I am sixty-four evaluating language markers of well-being in healthy aging narratives.

Natural language use is a promising candidate for the development of innovative measures of well-being to complement self-report measures. The type of words individuals use can reveal important psychological processes that underlie well-being across the lifespan. In this preregistered, cross-sectional study, we propose a conceptual model of language markers of well-being and use written narratives about healthy aging (N = 701) and computerized text analysis (LIWC) to empirically validate the model. As hypothesized, we identified a model with three groups of language markers (reflecting affective, evaluative, and social processes). Initial validation with established self-report scales (N = 30 subscales) showed that these language markers reliably predict core components of well-being and underlying processes. Our results support the concurrent validity of the conceptual language model and allude to the added benefits of language-based measures, which are thought to reflect less conscious processes of well-being. Future research is needed to continue validating language markers of well-being across the lifespan in a theoretically informed and contextualized way, which will lay the foundation for inferring people's well-being from their natural language use.

"Think positive and don't die alone" - Foreign-born, South Asian older adults' perceptions on healthy aging.

South Asians are the largest and fastest-growing racialized group in Canada, yet there are limited data on various aspects of health and well-being within this population. This includes the South Asian older adults' ethnoculturally informed perceptions of ageing. The study aimed to understand how social and cultural forces impact the meaning assigned to healthy ageing amongst older South Asians in Canada. We recruited with purposeful and snowball sampling strategies in Southern Ontario. We conducted in-depth focus group and individual interviews (n = 19) in five South Asian languages, employing a multilingual and cross-cultural qualitative approach. In our analysis, we identified three central themes: (a) taking care of body (b) taking care of mind and heart and (c) healthy ageing through the integration of mind and body. Our study demonstrates that older immigrants are a diverse and heterogeneous population and that their conception of healthy ageing is strongly influenced by their country of origin. This study also demonstrates how racialized foreign-born older adults might provide distinctive perspectives on the ageing process and on social theories of ageing due to their simultaneous immersion in and belonging to global majority and global minority cultures. This research also adds to the limited body of literature on the theories of ageing, despite migration trends, still has a white-centric lens.

Un punto de partida: opiniones de adultos sobre proyectos de vida para la vejez / A starting point: opinions of adults on life projects for old age

Contexto: El envejecimiento de la población plantea varias cuestiones fundamentales. ¿Cómo podemos ayudar a las personas a que sigan siendo independientes y activas a medida que envejecen? El Proyecto de Vida es un concepto que ha estado vinculado a la necesidad del ser humano de buscar su bienestar. Puede pensarse que, si una persona cuenta con un proyecto de vida preconcebido, al llegar a la vejez su tiempo estará orientado a continuar con metas previamente visualizadas. Objetivo: Conocer la opinión de los adultos sobre su proyecto de vida para la vejez en un área urbana de Tucumán. Metodología: Se realizó un estudio cualitativo desde un abordaje fenomenológico. Los sujetos estudiados fueron adultos entre 45-59 años, de ambos sexos. Se constituyeron dos grupos focales. Resultados: se obtuvieron las siguientes categorías descriptivas: "Un callejón ¿con salida?", "Descartados y desechos", "Encaminarnos a la vejez", "Revolución de la longevidad", "Un poco de esto, un poco de aquello". Conclusión: Este estudio evidenció las opiniones que tiene un grupo de adultos de Tucumán sobre proyectos de vida para la vejez, identificándose cómo el fenómeno de ageísmo influye en su proyección a futuro. Se vio la importancia de repensar la vejez sin la estigmatización o discriminación social, considerando acompañar activamente a la población en edad prejubilatoria (AU)

Context: The aging of the population raises several fundamental questions. How can we help people to remain independent and active as they age? The Life Project is a concept that has been linked to the need of human beings to seek their well-being. It may be thought that if a person has a preconceived life project, when they reach old age their time will be oriented to continue with previously visualized goals. Objective: To know the opinion of adults about their life project for old age in an urban area of Tucumán. Methodology: A qualitative study was carried out from a phenomenological approach. The subjects studied were adults between 45-59 years old, of both sexes. Two focus groups were formed. Results: the following descriptive categories were obtained: "An alley with an exit?", "Discarded and discarded", "Towards old age", "Longevity revolution", "A little of this, a little of that". Conclusion: This study evidenced the opinions that a group of adults from Tucumán have about life projects for old age, identifying how the phenomenon of ageism influences their future projection. The importance of rethinking old age without stigmatization or social discrimination was seen, considering actively accompanying the pre-retirement age population (AU)

Establishment of Clinical Construct of Intrinsic Capacity in Older Adults and Its Prediction of Functional Decline.

Background: The World Health Organization has conceptualised the health and healthcare of older adults around the concept of healthy ageing. Healthy ageing is defined as "the process of developing and maintaining the functional ability that enables well-being in older age". This functional ability is the sum of two key factors: intrinsic capacity and interacting environment. This concept of intrinsic capacity encompasses a wide spectrum of health characteristics including the physiological and psychological changes associated with the ageing process. In general, IC declines from a high and stable state to an impaired status as people age. Monitoring individuals for changes in intrinsic capacity in the context of their environment will provide a holistic method of tracking the functioning of older adults at both a population and individual level, providing an opportunity to address any reversible factors of decline. However, this would require a clear and objective conceptualisation of the concept of intrinsic capacity. Methodology: One hundred subjects were recruited via invitation by advertisement on the institute campus. Study participants underwent detailed physical examination and measurement of various physical and chemical biomarkers which were likely to represent intrinsic capacity as evidenced by the literature review. Outcomes measured were a decline in ADL, IADL, mortality and hospitalisation over a follow-up period of six months. Exploratory factor analysis (EFA) was done to obtain a clinical construct of the proposed entity of intrinsic capacity. Unpaired t-test and univariate logistic regression were used to check for the association between the composite score (IC) and its domains with the decline in ADL, IADL, mortality and hospitalisation. Results: One composite score (composite IC score) and eight subfactors emerged. The composite score and subfactor domains showed good construct validity. Composite intrinsic capacity score and subdomains of strength and cognition were significantly different among subjects with and without ADL and IADL decline. Univariate logistic regression showed that composite intrinsic capacity score was a predictor of decline in ADL and IADL even after adjusting for age, sex, comorbidity status and education level of the subject with an adjusted odds ratio of 0.99 and 0.98, respectively. Subdomains of strength and cognition also predicted a decline in ADL and IADL independently. Conclusion: The development of an objective construct of the concept of intrinsic capacity, using commonly measured clinical and biochemical parameters, is feasible and predictive of the subsequent functionality of an individual.

Association of entorhinal cortical tau deposition and hippocampal synaptic density in older individuals with normal cognition and early Alzheimer's disease.

Sites of early neuropathologic change provide important clues regarding the initial clinical features of Alzheimer's disease (AD). We have shown significant reductions in hippocampal synaptic density in participants with AD, consistent with the early degeneration of entorhinal cortical (ERC) cells that project to hippocampus via the perforant path. In this study, [11C]UCB-J binding to synaptic vesicle glycoprotein 2A (SV2A) and [18F]flortaucipir binding to tau were measured via PET in 10 participants with AD (5 mild cognitive impairment, 5 mild dementia) and 10 cognitively normal participants. In the overall sample, ERC tau was inversely associated with hippocampal synaptic density (r = -0.59, p = 0.009). After correction for partial volume effects, the association of ERC tau with hippocampal synaptic density was stronger in the overall sample (r = -0.61, p = 0.007) and in the AD group where the effect size was large, but not statistically significant (r = -0.58, p = 0.06). This inverse association of ERC tau and hippocampal synaptic density may reflect synaptic failure due to tau pathology in ERC neurons projecting to the hippocampus.

Building memories on prior knowledge: behavioral and fMRI evidence of impairment in early Alzheimer's disease.

Impaired memory is a hallmark of prodromal Alzheimer's disease (AD). Prior knowledge associated with the memoranda improves memory in healthy individuals, but we ignore whether the same occurs in early AD. We used functional MRI to investigate whether prior knowledge enhances memory encoding in early AD, and whether the nature of this prior knowledge matters. Patients with early AD and Controls underwent a task-based fMRI experiment where they learned face-scene associations. Famous faces carried pre-experimental knowledge (PEK), while unknown faces with which participants were familiarized prior to learning carried experimental knowledge (EK). Surprisingly, PEK strongly enhanced subsequent memory in healthy controls, but importantly not in patients. Partly nonoverlapping brain networks supported PEK vs. EK associative encoding in healthy controls. No such networks were identified in patients. In addition, patients displayed impaired activation in a right sub hippocampal region where activity predicted successful associative memory formation for PEK stimuli. Despite the limited sample sizes of this study, these findings suggest that the role prior knowledge in new learning might have been so far overlooked and underestimated in AD patients. Prior knowledge may drive critical differences in the way healthy elderly and early AD patients learn novel associations.

Measuring Cognitive Health in Ethnically Diverse Older Adults.

OBJECTIVES: Understanding racial/ethnic disparities in late-life cognitive health is a public health imperative. We used baseline data from the Kaiser Healthy Aging and Diverse Life Experiences (KHANDLE) study to examine how age, education, gender, and clinical diagnosis, a proxy for brain health, are associated with cross-sectional measures of cognition in diverse racial/ethnic groups. METHODS: Comprehensive measures of cognition were obtained using the Spanish and English Neuropsychological Assessment Scales and the National Institutes of Health Toolbox Cognitive Health Battery in a sample of 1,695 KHANDLE participants (Asians 24%, Blacks 26%, Latinos 20%, Whites 29%). A 25% random subsample was clinically evaluated and diagnosed with normal cognition, mild cognitive impairment (MCI), or dementia. Cognitive test scores were regressed on core demographic variables and diagnosis in the combined sample and in multiple group analyses stratified by racial/ethnic group. RESULTS: Race/ethnicity and education were variably associated with test scores with strongest associations with tests of vocabulary and semantic memory. Older age was associated with poorer performance on all measures, and gender differences varied across cognitive tests. Clinical diagnosis of MCI or dementia was associated with average decrements in test scores that ranged from -0.41 to -0.84 SD, with largest differences on tests of executive function and episodic memory. With few exceptions, associations of demographic variables and clinical diagnosis did not differ across racial/ethnic groups. DISCUSSION: The robust associations of cognitive test results with clinical diagnosis independent of core demographic variables and race/ethnicity support the validity of cognitive tests as indicators for brain health in diverse older adults.

The Roles of General and Domain-Specific Perceived Stress in Healthy Aging.

OBJECTIVES: Theoretical and empirical evidence suggests the existence of a general perceived stress factor overarching different life domains. The present study investigated the general perceived stress relative to domain-specific perceived stress as predictors of 26 diverse health outcomes, including mental and physical health, health behaviors, cognitive functioning, and physiological indicators of health. METHOD: A bifactor exploratory structural equational modeling approach was adopted in 2 aging samples from the Health and Retirement Study (N = 8,325 in Sample 1 and N = 7,408 in Sample 2). RESULTS: Across the 2 samples, perceived stress was well represented by a bifactor structure where there was a robust general perceived stress factor representing a general propensity towards stress perception. Meanwhile, after controlling for the general perceived stress factor, specific factors that represent perceived stress in different life domains were still clearly present. Results also suggested age, sex, race, education, personality traits, and past and recent stressor exposure as possible factors underlying individual differences in the general perceived stress factor. The general perceived stress factor was the most robust predictor of the majority of health outcomes, as well as changes in mental health outcomes. The specific factor of perceived neighborhood stress demonstrated incremental predictive effects across different types of health outcomes. DISCUSSION: The current study provides strong evidence for the existence of a general perceived stress factor that captures variance shared among stress across life domains, and the general perceived stress factor demonstrated substantial prospective predictive effects on diverse health outcomes in older adulthood.

Perceived Discrimination, Nativity, and Cognitive Performance in a Multiethnic Study of Older Adults: Findings From the Kaiser Healthy Aging and Diverse Life Experiences Study.

BACKGROUND: Despite growing research on the association between discrimination and disparities in cognitive aging, an evidence gap remains on how the association varies by racial/ethnic group. This study evaluates the associations of experiences of discrimination with cognitive function and whether these associations varied by race/ethnicity and nativity. METHOD: Using the Kaiser Healthy Aging and Diverse Life Experiences (KHANDLE) cohort (N = 1 712) with approximately equal groups of Black, White, Latino, and Asian community-dwelling older adults aged 65 years and older, we evaluated the associations between self-reported experiences of everyday and major lifetime discrimination with overall cognitive performance and domain-specific cognition (verbal episodic memory, semantic memory, and executive functioning) across race/ethnicity and nativity. Linear regression models examined the cross-sectional association between self-reported experiences of everyday and major lifetime discrimination with z-standardized coefficients for cognition. We tested for effect modification by race and nativity. All models controlled for age, sex, and education. RESULTS: Among KHANDLE participants (mean age: 76 years; SD: 6.8), everyday discrimination was not associated with cognitive scores. Major lifetime discrimination was associated with better average cognitive scores among Black participants but not among other racial/ethnic groups. Major lifetime discrimination was associated with better average cognitive scores among U.S.-born but not among non-U.S.-born individuals. CONCLUSION: Our findings do not imply that discrimination improves cognition, but rather suggest that future research should include more detailed measures on discrimination and unfair treatment that could help disentangle the extent to which relationships are causal or reflect some other underlying factor.

Influence of tDCS over right inferior frontal gyrus and pre-supplementary motor area on perceptual decision-making and response inhibition: A healthy ageing perspective.

A wide body of literature suggests that transcranial direct current stimulation (tDCS) administered over the prefrontal cortex can improve executive function - including decision-making and inhibitory control - in healthy young adults. However, the effects of tDCS in older adults are largely unknown. Here, using a double-blind, sham-controlled approach, changes in a combined perceptual decision-making and inhibitory control task were assessed before and after the application of tDCS (1 mA, 20 minute) targeting the right inferior frontal gyrus (rIFG) or pre-supplementary motor area (preSMA) in 42 young (18-34 years) and 41 older (60-80 years) healthy adults. Compared to sham stimulation, anodal tDCS over the preSMA improved decision-making speed for both age groups. Furthermore, the inhibitory control performance of older and younger adults was improved by preSMA and rIFG stimulation, respectively. This study provides evidence that tDCS can improve both perceptual decision-making and inhibitory control in healthy older adults, with the causal role of the preSMA and rIFG regions in cognitive control appearing to vary as a function of healthy ageing.

Efectos en adultos mayores de su participación en un proyecto comunitario basado en activos para la salud / Effects on older adults of their participation in a community project based on health assets

Introducción: el envejecimiento poblacional y el incremento de las enfermedades crónicas no transmisibles están generando un gran impacto en los sistemas de salud a nivel mundial. Articular el sistema de salud con los recursos comunitarios es fundamental para poder coordinar la atención sociosanitaria, descomplejizar la atención de los adultos mayores y promover el envejecimiento activo. Nuestro objetivo fue analizar la relación entre la participación de adultos mayores en un proyecto de mapeo de activos para la salud y los efectos percibidos en esta experiencia. Métodos: la intervención consistió en un taller de seis encuentros semanales donde se aprendió a reconocer activos para la salud. Estos fueron volcados en un mapa virtual de acceso libre y gratuito para ser compartido con toda la sociedad. En el taller también se reforzó la importancia de la relación entre los participantes para mejorar los apoyos sociales. Utilizamos un diseño cualitativo de tipo interactivo con una estructura interconectada y flexible de los componentes de la investigación. Se observaron las interacciones y diálogos que se produjeron entre moderadoras-participantes y participantes entre sí, y se incluyeron los registros del cuaderno de campo de las moderadoras. Al finalizar el último encuentro, y cumplidos tres meses, se realizaron entrevistas en profundidad a quienes asistieron, al menos, a la mitad de los encuentros. Se utilizó una guía con preguntas abiertas, para conocer la perspectiva de los participantes acerca de eventuales cambios percibidos a partir de la experiencia vivida en el taller. Los datos se categorizaron y, posteriormente, se triangularon para garantizar la validez del análisis. Resultados: se identificaron las siguientes categorías que sitúan las experiencias de los participantes en relación con su paso por el proyecto: la generación de vínculos entre pares, los vínculos con las moderadoras, la dinámica de taller, la sustentabilidad del proyecto y la resignificación del barrio. Conclusión: es factible generar cambios positivos en la salud de los adultos mayores, potenciar los espacios de socialización y contribuir satisfactoriamente en la resignificación de los barrios a través del mapeo de activos para la salud.

Introduction: population ageing and the increase in chronic non-communicable diseases are having a major impact on health systems worldwide. Linking the health system with community resources is essential in order to coordinate social and health care, decomplexify the care of older adults and promote active ageing. Our objective was to analyse the relationship between the participation of older adults in a health asset mapping project and the perceived effects of this experience. Methods: the intervention consisted of a workshop of six weekly meetings where participants learned to recognise health assets from the perspective of each participant. These were then uploaded onto a virtual map that could be accessed free of charge and shared with the whole of society. The workshop also reinforced the importance of the relationship between participants to improve social support.We used an interactive qualitative design with an interconnected and flexible structure between the research components. The interactions and dialogues that took place between moderators-participants and participants with each other were observed, and the field notebook records of the moderators were included. At the end of the last meeting, and after three months, in-depth interviews were conducted with those who attended at least half of the meetings. A guide with open-ended questions was used to find out the participants perspective on possible changes perceived as a result of the workshop experience. The data were categorised and then triangulated to ensure the validity of the analysis. Results: the following categories were identified that situate the participants experiences in relation to their time in the project: the generation of links between peers, the links with the moderators, the workshop dynamics, the sustainability of the project and the re-signification of the neighbourhood. Conclusion: it is feasible to generate positive changes in the health of older adults, to strengthen the spaces for socialisation and to successfully contribute to the resignification of the neighbourhoods through the mapping of assets for health.

The association of widowhood and living alone with depression among older adults in India.

Widowhood is a catastrophic event at any stage of life for the surviving partner particularly in old age, with serious repercussions on their physical, economic, and emotional well-being. This study investigates the association of marital status and living arrangement with depression among older adults. Additionally, the study aims to evaluate the effects of factors such as socio-economic conditions and other health problems contributing to the risk of depression among older adults in India. This study utilizes data from the nationally representative Longitudinal Ageing Study in India (LASI-2017-18). The effective sample size was 30,639 older adults aged 60 years and above. Descriptive statistics and bivariate analysis have been performed to determine the prevalence of depression. Further, binary logistic regression analysis was conducted to study the association between marital status and living arrangement on depression among older adults in India. Overall, around nine percent of the older adults suffered from depression. 10.3% of the widowed (currently married: 7.8%) and 13.6% of the older adults who were living alone suffered from depression. Further, 8.4% of the respondents who were co-residing with someone were suffering from depression. Widowed older adults were 34% more likely to be depressed than currently married counterparts [AOR: 1.34, CI 1.2-1.49]. Similarly, respondents who lived alone were 16% more likely to be depressed compared to their counterparts [AOR: 1.16; CI 1.02, 1.40]. Older adults who were widowed and living alone were 56% more likely to suffer from depression [AOR: 1.56; CI 1.28, 1.91] in reference to older adults who were currently married and co-residing. The study shows vulnerability of widowed older adults who are living alone and among those who had lack of socio-economic resources and face poor health status. The study can be used to target outreach programs and service delivery for the older adults who are living alone or widowed and suffering from depression.

Monitoring patients' health, mobility, mentation, and ability to maintain social connections can help you promote healthy aging for your older patients.

Active Aging through Volunteerism: A Longitudinal Assessment of Perceived Neighborhood Safety as a Predictor among Older Adults, 2008-2018.

Volunteering can play an important role in active aging. The resource theory of volunteering posits that volunteerism depends on human, social, and cultural capital. Benefits of volunteering have been documented at the micro-, meso-, and macrolevels, positively affecting individual older people as well as their local communities and society at large. Taking a process-oriented theoretical approach, this study focused on the mesolevel factor of the environment with the purpose of determining the relationship between perceived neighborhood safety and volunteerism over the course of a decade and the extent to which this relationship differs by gender and race. Longitudinal data from the Health and Retirement Study in the United States of America between 2008 and 2018 were used (N = 72,319 adults 60 years and older). Generalized estimating equations (GEE) with robust standard errors were employed while controlling for a number of covariates. A third of the sample volunteered in the past year (33%). The probability of volunteering among older adults who rated their perceived neighborhood safety as excellent was greater compared with those who rated their perceived neighborhood safety as fair/poor after controlling for all other model covariates (ME: 0.03, 95% CI: 0.02, 0.05). Among males rating their perceived neighborhood safety as excellent, the probability of volunteering was higher (ME: 0.04, 95% CI: 0.02, 0.07). Among females, the probability of volunteering was higher among those who perceived their neighborhood safety to be excellent (ME: 0.03, 95% CI: 0.01, 0.05) or very good (ME: 0.02, 95% CI: 0.00, 0.04). White respondents who rated their neighborhood safety as excellent (ME: 0.05, 95% CI: 0.03, 0.07) or very good (ME: 0.04, 95% CI: 0.02, 0.06) had a higher probability of volunteerism. Results were not significant among Black respondents and those who described their race as "other." This study's process-oriented theoretical approach indicates that initiatives aimed at improving neighborhood safety and older adults' perceptions of neighborhood safety could increase social capital and lead older adults to engage in more volunteering, providing benefits at micro-, meso-, and macrolevels-to older individuals, their local communities, and society at large.

The Self-Regulation of Healthy Aging: Goal-Related Processes in Three Domains.

As people age, they experience typical age-graded challenges and opportunities, for example, their own retirement, changes in their social networks, or a decline in health condition. The extent to which people successfully process, respond to, and act on these challenges and opportunities is highly important for their health, at the core of which the WHO sees the possibility of "doing what one has reason to value." In this article, we posit that individuals can play an active role in determining whether they can, in response to these age-graded influences, continue doing what they have reason to value, and that they can do so by deploying the self-regulatory processes of goal setting (including reengagement in new goals after disengaging from a previous goal), goal pursuit, and goal disengagement. We discuss the role of these self-regulatory processes in three important goal domains: work/retirement, interpersonal relationships, and health. Across these domains, we consider typical challenges and opportunities including the increased availability of daily time in old age, the long past that lies behind older adults, and their limited future time perspective. Finally, we derive open research questions that may be studied to better understand how the very old may self-regulate their response to age-graded influences.

Effort Mobilization and Healthy Aging.

Healthy aging is in part dependent upon people's willingness and ability to mobilize the effort necessary to support behaviors that promote health and well-being. People may have the best information relating to health along with the best intentions to stay healthy (e.g., health-related goals), but positive outcomes will ultimately be dependent upon them actually investing the necessary effort toward using this information to achieve their goals. In addition, the influences on effort mobilization may vary as a function of physical, psychological, and social changes experienced by the individual across the life span. Building on the overall theme of this special issue, we explore the relationships between motivation, effort mobilization, and healthy aging. We begin by characterizing the relationship between motivation and effort, and identify the factors that influence effort mobilization. We then consider the factors associated specifically with aging that may influence effort mobilization (e.g., changes in cardiovascular and neural mechanisms) and, ultimately, the health and well-being of older adults. Finally, distinguishing between those influential factors that are modifiable versus intractable, we identify ways to structure situations and beliefs to optimize mobilization in support of healthy aging.

Goal Changes and Healthy Aging.

This article discusses ways in which aging individuals respond to physical, social, and environmental changes and constraints by modifying their goals. We review aging-related trends, which we derive from several theoretical approaches, including goal systems theory, the motivational theory of life-span development and its action-phase model, and the Selection, Optimization, and Compensation model. These theories explain how biological and social role changes in later adulthood prompt individuals to make changes to the content, orientation, and composition of their goals, including disengaging from and adjusting previously central goals. They also help identify individual differences in the capacity to do so effectively. We review several motivation-related interventions that address the challenges in goal adjustment and call for more research on identifying processes of goal changes conducive to healthy aging, more interventions, and modifications of societal and institutional (e.g., workplace, nursing home) operations that support adaptive goal change in older adults.

Healthy Aging-Relevant Goals: The Role of Person-Context Co-construction.

OBJECTIVES: This article considers how individuals' motivation for healthy aging manifests within the myriad of different contexts that older adults are embedded in as they move through later life. METHODS: Drawing on the concept of co-construction, we argue that persons and contexts both contribute to the emergence, maintenance, and disengagement from healthy aging relevant goals in adulthood and old age. RESULTS: To promote the understanding of such co-constructive dynamics, we propose four conceptual refinements of previous healthy aging models. First, we outline various different, often multidirectional, ways in which persons and contexts conjointly contribute to how people set, pursue, and disengage from health goals. Second, we promote consideration of context as involving unique, shared, and interactive effects of socio-economic, social, physical, care/service, and technology dimensions. Third, we highlight how the relevance, utility, and nature of these context dimensions and their role in co-constructing health goals change as individuals move through the Third Age, the Fourth Age, and a terminal stages of life. Finally, we suggest that these conceptual refinements be linked to established (motivational) theories of lifespan development and aging. DISCUSSIONS: In closing, we outline a set of research questions that promise to advance our understanding of the mechanisms by which contexts and aging persons co-construct healthy aging relevant goals and elaborate on the applied significance of this approach for common public health practices.

Using Theories of Behavior Change to Develop Interventions for Healthy Aging.

Healthy aging requires people to adopt and maintain beneficial behaviors in all stages of the life span. Supporting behavior change, including via the motivation to make and maintain those changes, is therefore important for the promotion of healthy aging. The aim of this overview is to introduce theoretical frameworks from the psychology of motivation that lend themselves to the development of effective interventions promoting behavior change conducive to healthy aging. We discuss theoretical frameworks referring to the determinants, properties, and functionality of goals aimed at behavior change, and consider the implications of the various theories for designing interventions to support healthy aging. We first consider theories that focus on beliefs and attitudes as determinants of goals, then we address theories that focus on the structure and content as important properties of goals, and, finally, we examine theories drawing on conscious and nonconscious processes underlying the functionality of these goals. We will present if-then planning and mental contrasting, as well as nudging and boosting, that is, novel strategies of behavior change that support the creation of scalable interventions for healthy aging across the life span. Against this background, new perspectives emerge for modern, state-of-the-art, and individually tailored interventions with the aim of enhancing older people's healthy living.
