Background Behavioral science researchers are increasingly collecting detailed location data such as second-by-second GPS tracking on participants due to increased ease and affordability. While intraindividual variability has been discussed in the travel literature for decades, traditional methods designed for studying individual differences in cen...
Article
Falls are not only a leading cause of death and disability, but also a strain on the capacity for caregivers to provide care. This study examined how the context of caregiving relates to the importance of caregiver-defined mobile fall prevention feature sets. A sample of 266 family caregivers, recruited from a Chinese social media platform, reporte...
Article
Objectives Fear of falling is common among older adults and can increase fall-risk through premature activity restriction. Exergames, an emerging tool in fall prevention, combine exercise with interactive and adaptive game elements. This review examines the extent to which exergame interventions reduce fear of falling among community-dwelling older...

Assistive technologies are an essential component of meeting the needs of an aging population. With advancing age, chronic conditions and physiological changes can result in impaired lower limb function among older adults, which may in turn limit their ability to perform daily activities or even walking. Informed by the continuity theory, we concep...
Article
Full-text available
Beliefs about aging are grounded in social experience. This study considers the extent to which married older adults’ shared beliefs about aging and markers of aging maintain a concurrent and enduring association with their partners’ beliefs and markers of aging. Data from the 2010/2012 and 2014/2016 waves of the Health and Retirement Study provide...

Research suggests that grandparent-grandchild dyads shift in degree of solidarity over extended periods of time (e.g. Moorman & Stokes, 2016), but no work has considered grandparent-grandchild interactions microlongitudinally. This study utilized microlongitudinal data with an emphasis on intraindividual variability to examine the daily processes a...
Article
Full-text available
Digital communication technologies expand opportunities for social interactions and as a result have the potential to either amplify or dampen the coupling of social interactions with well-being in daily life. We use data from the 100-day Personal Understanding of Life and Social Experiences project (n = 99, age = 50 – 88) to examine variation in t...
Article
Full-text available
As adults age into a digitally connected world, communication technologies such as the internet, email, social media, and video chats offer new opportunities to connect with others. The implications of older adults’ use of technology in the context of their social relationships—such as the implications for social integration, the relational circums...
Article
Full-text available
Life-span perspectives on adult development and aging highlight the processes of understanding and acting to support one’s own health and well-being. Within this framework, subjective measures offer insight into the experience of objective measures of health. This symposium brings together four papers that highlight the overlap and discrepancy betw...
Article
Full-text available
Older adult populations are known for their diversity in health. Within couples, however, population studies have documented exceptional levels of spousal similarity in health and health behaviors. The presence of spousal similarity in health among older adults suggests a process of convergence, yet few studies have examined this phenomenon longitu...
Article
Full-text available
An accurate understanding of one’s abilities and limitations allows adaptive response to the challenges that are faced in daily life. However, older adults may over or under estimate their actual abilities. The Daily Balance Project examined the intraindividual dynamics of older adults’ perceived balance with objective measures of balance and physi...
Article
Accelerometer measurements are frequently reported as total weekly activity counts (AC). Methods of utilizing activity parameters to allow differentiation of activity intensities (i.e., manually derived cut-points) have been described. While this information may provide valuable data for researchers, only few investigators have utilized these metho...
Article
Aim: To quantify variations in health-related behaviors (HRB) clustering of older adults in Western and Eastern countries. Methods: Using six aging cohorts from the USA, England, Europe, Japan, Korea and China, latent class analysis was applied to access the clustering of smoking, alcohol consumption, physical activity and social activity. Resu...

Background and objectives: Almost one-third of older adults report experiencing age discrimination. We hypothesized sequential links between older adults' everyday experiences of age discrimination and future health behaviors related to cancer risk through self-perceptions of aging (SPA). Research design and methods: Participants were community-...
Article
The cost of adaptation to experiences across the life course is reflected in multisystem markers of biologic strain. Processes of adaptation, however, do not occur in isolation, but rather in the company of close social partners. This study integrates data on self-reported, physical, and biological measures of health and life experiences from the 2...

Purpose of the Study Individual beliefs are known to be predictive of health. This study examines the co-construction of couple norms and links couples’ shared beliefs about aging to future individuals’ and couples’ functional limitations. Design and Methods Data from the 2008 and 2014 waves of the Health and Retirement Study (1,231 couples; age r...
Article
Self-perceptions of aging (SPA) are important for future health outcomes. Spouses in older adulthood are known to be linked in their health and well-being and may also co-construct beliefs about their own aging. This paper examines the link between spouses shared beliefs about their own aging and functional limitations six years later. HRS data fro...
Article
Goals and self-regulation have important roles for achieving and maintaining resources that are meaningful for adaptation in the face of multiple losses with aging. Despite the fact that goals and affect likely drive one another, relatively little empirical research has examined the processes involved in self-regulating health goals and emotional s...
Article
In addition to being a sedentary activity with health and well-being correlates, TV watching is also one of the most commonly reported daily activities among older adults. Despite especially high variability in time spent watching TV in this age group, personality has not been well integrated into explanations of that variation, or the study of con...
Conference Paper
Technology users are collecting data about themselves at an astounding rate. This explosion of data collection has not been matched by users’ abilities to assimilate and apply this information. Visualization is a key means of bridging this gap, however, most approaches to visualization neglect individual differences, and focus instead on one-size-f...
Article
Development in adulthood occurs through the process of setting and working toward goals. Emotions link experiences to goals and action, and are integral to goal setting and goal pursuit. The simultaneous experience of positive and negative or ‘mixed’ emotions coheres with the complexity of goal pursuit within the context of competing demands in dai...
Article
Objective: We conceptualize successful aging as a cumulative index of individual resources (the absence of disease and disability, high cognitive and physical functioning, social embeddedness) in the service of successful aging outcomes (global well-being, experienced well-being, and vital status), and conditioned by age, social structure, and envi...
Article
This study investigates gender differences in trajectories of support from close relationships among adults in the transition from middle to old age, taking into account stability and change in the identity of the closest persons. Multi-level modelling was used to estimate gendered age-trajectories in three dimensions of support: emotional support,...
Article
Objectives. The “Great Recession” shocked the primary institutions that help individuals and families meet their needs and plan for the future. This study examines middle-aged adults’ experiences of financial loss and considers how socioeconomic and interpersonal resources facilitate or hinder maintaining a sense of control in the face of economic...
Article
Age-based self-stereotyping is associated with a variety of long-term physical health and psychological well-being outcomes for older people. However, little is known about how older individuals' day-to-day experiences of functional limitations may be related to concurrent self-appraisals on dimensions representing negative age stereotypes. We exam...
Article
Close social partners may contribute to or detract from older adults' health and well-being, in part because daily emotions are closely coupled with the quality of daily social interactions. This study examines variation in this sensitivity to interactions with social partners across the contexts of emotional closeness, interactions with others, an...
Conference Paper
Minimizing time spent in the hospital is a preferred outcome for individuals at the end of life. We compare days spent in the hospital during the last 6 months of life in residents of a social model care facility (N = 90) with a nationally representative sample of community (N = 330) and long term care (N = 187) residing respondents from the 2008 a...
Article
The growing empirical base of studies on intraindividual variability speaks to its increasing importance in understanding human development. Studying intraindividual variability by definition requires multiple measurement occasions (e.g., microlongitudinal assessment). Tracking how intraindividual variability changes over time requires that the mic...
Article
Lifespan development involves setting and pursuing self-guided goals. This study examines how in the social domain, possible selves, a future-oriented self-concept, and self-regulation, including self-regulatory beliefs and intraindividual variability in self-regulatory behavior, relate to differences in overall daily social goal progress. An onlin...
Conference Paper
Examining relationship processes in the context of self and daily experiences provides insight into how the self-system may guide distinct regulatory strategies in daily life. Using data from the Personal Understanding of Life and Social Experiences (PULSE) project, this study links regulation to self by examining variation in relationship processe...
Conference Paper
While research has shown that the majority of age-related physiological changes are deleterious, emotion regulation appears to improve or remain stable well into later life, with the exception of returning to homeostasis following a stressor. Following an extensive interdisciplinary literature review, we have developed a model that connects aging,...
Conference Paper
Evaluation and comparison is an essential component of self-regulation and adult development. Web-based microlongitudinal studies that direct participants to visualizations of their responses provide an opportunity to understand under what circumstances individuals interact with visualizations of their data. To examine the qualities of a day that p...
Article
The goal for this study was to examine within-person processes driving individual development related to social goals. We examined how social regulatory processes travel together over time to understand whether daily social goal progress is sensitive to variation in experiences of support and hindrance and the extent to which maintenance or achieve...
Article
Objectives: The structure and function of older adults' social convoys contribute to health and well-being in later life, but little is known about how they may shape one another. In this study, we consider relationship quality as a within-person process by examining its covariation with social goal progress and investigate variation in these rela...
Article
Personality traits, goals, and perceived stress were examined in 99 older adults assessed via web-based surveys over 100 days to explore how traits influence self-regulation. Participants high in neuroticism made less social goal progress and those high in conscientiousness and extraversion made more health and social goal progress over the 100-day...
Conference Paper
Ambivalence is ubiquitous across resident, staff, and family members’ interactions in long-term care. The formation of alternative family structures in long-term care environments may reconcile these feelings by fostering a sense of place and home among participants, as they transition into new roles and expectations. Our study explores how these a...
