Participation in activities mediates the effect of Internet use on cognitive functioning in old age.

Research indicates that Internet use positively influences cognitive functioning in later life, but we do not know the behavioral pathways that explain this association. This study explored the role of participation in activities as a potential mediator of the relationship between Internet use and cognitive functioning over a 4-year period. We analyzed representative data from the Survey of Health, Ageing and Retirement in Europe (SHARE). The sample included 8353 European participants between 50 and 97 years of age. We used data from 2013 (T1), 2015 (T2), and 2017 (T3). Participants reported whether they participated in a diverse range of social and leisure activities. In addition, they provided information about their Internet use as well as cognitive functioning measures. Findings from cross-lagged panel analysis indicated a positive association between Internet use and change in cognition over the course of 4 years. This relationship was partly mediated by the number of reported activities. Internet use was positively associated with the change in activities after 2 years, which, in turn, positively predicted cognitive functioning 2 more years later. This is the first study that explores the temporal sequence of Internet use, participation in activities, and cognitive functioning. It sheds light on the mechanisms that account for the positive effects of Internet use on healthy aging.

Social support is associated with technology use in old age.

BACKGROUND: The use of technological innovations can play a significant role in healthy aging and social participation in old age; however, it is not well understood how social contexts can influence or support older adults' use of technology. This study explored the associations between technology use, perceived technology-related support and actual technology-related social support. It was expected that older adults who perceived having more supportive resources available would be more likely to receive actual support in technology-related issues, which, in turn would explain a greater use of technology in everyday life. MATERIAL AND METHODS: The data are based on a sample of 107 community-dwelling older adults between 60 and 93 years of age (mean age = 73.66 years, 40% male). Measures included self-reports of actual technology-related support, perceived technology-related support, the use of different devices related to digital information and communication technology and personal characteristics (e.g. chronological age, gender, education and functional limitations). A path model was used to explore the research hypotheses. RESULTS: Actual technology-related support received was positively associated with a greater number of devices used. Participants received more support with technology when they perceived a greater availability of supportive resources. The actual support received mediated the influence of perceived support and functional limitations on technology use. CONCLUSION: The results of this study show that the provision of supportive behavior is associated with the actual use of technology. Moreover, the findings shed light on the individual and contextual factors that explain differences in actual support received.

Subjective Technology Adaptivity Predicts Technology Use in Old Age.

BACKGROUND: To date, not much is known about the psychological and motivational factors underlying technology use in late life. What are the interindividual determinants that lead older adults to invest in using technological innovations despite the age-related physiological changes that impose challenges on behavioral plasticity in everyday life? OBJECTIVE: This research explores interindividual differences in subjective technology adaptivity - a general technology-related motivational resource that accounts for technology use in late life. More specifically, we investigate the influence of this factor relative to demographic characteristics, personality traits, and functional limitations in a longitudinal sample of community-dwelling older adults. METHODS: We report results from a paper-and-pencil survey with 136 older adults between 59 and 92 years of age (mean = 71.4, SD = 7.4). Of those participants, 77 participated in a 2-year follow-up. We assessed self-reports of technology use, subjective technology adaptivity, functional limitations, and the personality traits openness to new experiences and neuroticism. RESULTS: Higher levels of subjective technology adaptivity were associated with technology use at the first measurement as well as increased use over the course of 2 years. CONCLUSIONS: Subjective technology adaptivity is a significant predictor of technology use in old age. Our findings contribute to improving the understanding of interindividual differences when using technological innovation in late life. Moreover, our findings have implications in the context of user involvement and may contribute to the successful development of innovative technology for older adults.

Cognitive Functions Buffer Age Differences in Technology Ownership.

BACKGROUND: Technology plays a major role in enhancing quality of life and everyday competence in old age. Mechanic and pragmatic cognitive functions are known to serve as resources when using technology in everyday life. Not much is known about the differential role of mechanic and pragmatic cognitive functions when moderating reduced technology ownership in old age. OBJECTIVE: In this research, we explored whether perceptual speed or verbal fluency is more important for buffering age differences in technology ownership. We investigate possible moderation effects of cognitive functions relative to demographic characteristics, socioeconomic status, and household composition variables. METHODS: We report findings based on a nationally representative German sample of 3,357 younger and older adults between 18 and 94 years of age (mean = 51.2, SD = 17.3). Interaction and relative importance analyses were conducted to examine the relative importance of perceptual speed and verbal fluency for the moderation of age differences in technology ownership across adulthood. RESULTS: Findings suggest that perceptual speed (B = 0.0008, t = 6.23, p < 0.001) and verbal fluency (B = 0.0003, t = 2.70, p < 0.01) buffered age differences in technology ownership. The moderating role of perceptual speed remained robust (B = 0.0007, t = 5.48, p < 0.001) when including interactions of age with demographic, socioeconomic, and household composition variables; however, the interaction between age and verbal fluency was no longer significant (B = 0.0002, t = 1.82, p = 0.069). Relative importance analysis indicates that perceptual speed was the most important moderator of age differences (DW = 0.0121), whereas verbal fluency was less important for moderating the relation between age and technology ownership (DW = 0.0039). CONCLUSIONS: Mechanic and pragmatic cognitive functions may serve differently as moderators of the relation between age and technology ownership. Our findings suggest that perceptual speed was more important for buffering age differences in technology ownership than verbal fluency. Such findings underscore the relevance of information processing for the ownership of technological devices in late life.

Outdoor motivation moderates the effects of accessibility on mobility in old age.

BACKGROUND: Mobility plays a major role in healthy aging and social participation. This study explored whether accessibility problems in the housing environment are negatively associated with mobility in old age and whether this association is moderated by differences in an individual's preference for spending time outside the home (outdoor motivation). MATERIAL AND METHODS: This article reports the results of a research project on mobility in old age. The project included a survey study of 120 community-dwelling older adults between 59 and 92 years of age (mean = 71.7 years, SD = 7.3 years) living in the metropolitan region of Nuremberg, Germany. Objective assessments were conducted in the participants' housing environment to evaluate the magnitude of accessibility problems. RESULTS: Accessibility problems were negatively associated with mobility. Interaction analyses suggested a buffering effect of outdoor motivation on this association, i.e. participants who reported a preference for spending time outside the home had a higher mobility in the face of accessibility problems as compared with those who preferred staying at home. CONCLUSION: Outdoor motivation may have protective effects for older adults when accessibility problems challenge mobility. These findings contribute to improving the understanding of how and under what circumstances older adults stay mobile and active in everyday life. Considering interindividual differences in outdoor motivation may binterventions and public health programs that are aimed at enhancing mobility and social participation in old age.

COVID-19 and perceiving finitude: Associations with future time perspective, death anxiety, and ideal life expectancy.

The coronavirus pandemic threatens the health, future, and life of individuals and might hence accentuate perceptions of the fragility and finitude of life. We investigated how different perceptions of the pandemic (regarding the virus as a health threat and perceiving social and financial restrictions due to the pandemic) relate to different perceptions of life's finitude (i.e., future time perspective, death anxiety, and ideal life expectancy). Using longitudinal data from 1,042 adults (68% women; aged 18-95 years) gathered within the first and within the second peak of the pandemic in Germany, we expected decreases in future time perspective and ideal life expectancy, as well as increases in death anxiety in response to threatening perceptions of the pandemic. The results indicated decreasing future time perspectives, an accentuation of death anxiety right at the beginning of the pandemic, as well as stable ideal life expectancies. There was a tendency for more pronounced change among older adults. Initial levels and changes in the perceptions of finitude could partly be explained by initial and changing perceptions of the pandemic. Next to perceptions targeting the threat of the virus itself, perceptions of strong social and financial restrictions during the pandemic contributed to an altered stance toward the finitude of life. Concluding, we discuss stability and variation in perceptions of the finitude of life during a time of major societal change and a potentially life-threatening pandemic.

Technology Adaptivity Mediates the Effect of Technology Biography on Internet Use Variability.

BACKGROUND AND OBJECTIVES: Increasing numbers of older adults use the internet, but relatively little is known about the range and determinants of different online activities among older internet users. This study explores the interplay between technology-related biographical experiences and subjective technology adaptivity to explain the variability of internet use. Older adults who report having had more biographical experiences with technologies were expected to use a greater range of online activities. In addition, subjective technology adaptivity was expected to serve as a mediator of this relationship. RESEARCH DESIGN AND METHODS: The analyses are based on a sample of 707 community-dwelling older participants of the University of the Third Age between 60 and 95 years of age (mean age = 72.49 years; 48% female) who use the internet. The measures include self-reports of online activities, technology-related biographical experiences, subjective technology adaptivity, and personal characteristics (age, gender, education, income, living-together status, and subjective health). Correlations and a path model with mediator effects were used to explore the research hypothesis. RESULTS: The bivariate effects on the variability of internet use showed that study subjects participated in a greater range of online activities when they lived together with other people and were male, younger, and had higher levels of subjective technology adaptivity, technology-related biographical experiences, and educational level. The direct effects on the mediator show higher levels of subjective technology adaptivity for people who reported greater technology-related biographical experiences and for those who reported higher levels of subjective health. DISCUSSION AND IMPLICATIONS: The results show that the positive association between people's past experiences with and stances toward technology in their own lifetimes and their range of diverse internet activities is mediated by subjective technology adaptivity. The findings also help to illustrate which biographical factors and which current individual factors explain differences in actual online behavior.

Internet Use and Cognitive Functioning in Late Adulthood: Longitudinal Findings from the Survey of Health, Ageing and Retirement in Europe (SHARE).

OBJECTIVES: Research suggests that cognitive functioning is associated with technology use in late life, but longitudinal research in this domain is still sparse. This study explored the reciprocal association between Internet use and cognitive functioning over a 2-year period. METHOD: We analyzed representative data across 14 countries from the Survey of Health, Ageing and Retirement in Europe (SHARE). The sample included 29,576 participants between 50 and 100 years of age. We used data from 2013 (Wave 5) and a 2-year follow-up in 2015 (Wave 6). Participants provided information on cognitive functioning measures and Internet use at both time points. RESULTS: Cross-lagged panel analysis indicated reciprocal effects between cognitive functioning and Internet use. Internet use had a greater impact on cognitive functioning than vice versa. DISCUSSION: This study sheds light on the direction of the association between cognitive functioning and Internet use. Findings indicate that using the Internet positively affects cognitive functioning in late life.

Negative Self-perception of Aging and Mortality in Very Old Chinese Adults: The Mediation Role of Healthy Lifestyle.

OBJECTIVES: Previous literature has consistently shown a positive association between negative self-perception of aging and mortality in middle-aged and older adults. However, two questions remain unsolved: (a) whether such association holds among very old people (i.e., the fourth age) and (b) the potential mediators that could contribute to the positive association. This study sought to fill in the research gap by examining the association between self-perception of aging and mortality in a group of very old Chinese participants (i.e., aged over 78 years). METHODS: Four waves of data across a span of 8 years (2000-2008) were obtained from the Chinese Longitudinal Healthy Longevity Survey, which measured a total of 9,683 participants' negative self-perception of aging, survival status, cognitive functioning, diet, as well as other demographic information. RESULTS: Latent growth models with survival analysis were conducted, and the results replicated previous findings indicating an association between negative self-perceptions of aging and reduced survival. Moreover and more importantly, a potential mediator-healthy lifestyle (e.g., eating fresh vegetables and fruits, exercising regularly, and no smoking)-was identified, such that older adults with more negative self-perception of aging tended to engage in less healthy lifestyle, which could lead to increased risk of mortality. DISCUSSION: The findings provided support for a longitudinal behavioral pathway of health, linking negative perceptions of aging to mortality, and also yielded important practical implications for older adults to reach longevity.

The Detrimental Consequences of Overestimating Future Health in Late Life.

OBJECTIVES: Although forecasting a positive future can be adaptive, it may not be when expectations are unmet. Our study examined whether such inaccurate expectations about future health status (overestimation) were maladaptive for older adults who commonly experience late life declines in physical functioning. METHOD: We analyzed data from the nationally representative German Aging Survey (DEAS; 1996-2011; n = 2,539; age range 60-85 years) using multilevel growth models that assessed the influence of inaccurate health expectations on older adults' physical functioning over a 9-year period. RESULTS: Overestimating future health status predicted reduced day-to-day physical functioning when age, gender, and self-rated health were controlled. A Time × Overestimation interaction indicated that the negative effects of overestimation on physical functioning became more pronounced over the 9-year period. DISCUSSION: Results suggest that repeatedly unmet health expectations may undermine motivational resources and accelerate late life declines in physical functioning.

German Version of the Inventory of Motivations for Hospice Palliative Care Volunteerism: Are There Gender Differences?

The present study examined gender differences in motivations for volunteering for hospice using a German version of the Inventory of Motivations for Hospice Palliative Care Volunteerism (IMHPCV). The IMHPCV was translated into German and back-translated into English following the World Health Organization's guidelines for the translation and adaptation of instruments. In an online survey, 599 female and 127 male hospice volunteers from hospice organizations throughout Germany completed the translated version of the IMHPCV, the Scales of the Attitude Structure of Volunteers as well as questions pertaining to their volunteer experience. Based on an exploratory structural equation modeling approach, adequate model fit was found for the expected factor structure of the German version of the IMHPCV. The IMHPCV showed adequate internal consistency and construct validity. Both female and male hospice volunteers found altruistic motives and humanitarian concerns most influential in their decision to volunteer for hospice. Personal gain was least influential. Men rated self-promotion, civic responsibility, and leisure as more important than women. Analyses provided support for the use of the IMHPCV as a measurement tool to assess motivations to volunteer for hospice. Implications for recruitment and retention of hospice volunteers, in particular males, are given.
