Losses that occur with age can create barriers to meaningful activity engagement, a crucial aspect of ageing well. Research on this topic is frequently qualitative, with few studies accessing large community samples. This study (a) assessed the frequency specific personal and environmental barriers (such as poor health and limited transport access), identified by older adults in previous research, were endorsed; (b) used latent class analysis (LCA) to identify population subgroups based on combinations of these barriers, and (c) examined associations of subgroups with purpose in life and quality of life.Four hundred and thirty-two randomly selected Australian adults aged 65+ years (average age 76.7, 58% female) completed a telephone survey. They were asked whether certain barriers affected engagement and provided data on sense of purpose and quality of life.Physical health/mobility were the most frequently reported barriers, followed by sensory difficulties, financial limitations, and caring responsibilities. The LCA revealed up to three subgroups/classes of participants according to the barriers endorsed. Class 1 had low endorsement of all barriers, including physical health. The majority of Class 2 endorsed physical health barriers and other barriers more frequently than Class 1. Class 3 were comparable to Class 2, but also frequently endorsed community access barriers. Class 1 were younger and reported a greater sense of purpose and higher quality of life.Physical health/mobility barriers to engagement are those most frequently endorsed by older adults. These barriers may increase vulnerability to, or exacerbate the impact of additional barriers, such as sensory difficulties, access to transport and lack of finances.

Objectives We test whether higher awareness of age-related gains (AARC-gains), lower awareness of age-related losses (AARC-losses), and more positive attitudes towards own aging (ATOA) are cross-sectionally related to more frequent social media use. We also investigate the strength and direction of the associations of AARC-gains, AARC-losses, and ATOA with social media use over one-year, from before to after the onset of the COVID-19 pandemic. Methods We used cross-sectional data of 8320 individuals (mean age= 65.95 years; SD= 7.01) and longitudinal data of a subsample of 4454 individuals participating to the UK PROTECT study in 2019 and 2020. We used ordered regression models, linear regression models, and tests of interaction. Models were adjusted for age, sex, education, and employment. Results Higher AARC-gains and more positive ATOA, but not AARC-losses, were cross-sectionally associated with more frequent social media use. Social media use become more frequent at follow-up. In the longitudinal models controlling for baseline levels of the outcome variable, more frequent baseline social media use predicted increases in AARC-gains, whereas baseline AARC-gains did not significantly predict frequency of social media use at follow-up. Baseline frequency of social media use did not significantly predict AARC-losses, nor ATOA at follow-up, whereas lower levels of AARC-losses and more positive ATOA predicted more frequent social media use at follow-up. Discussion Although effect sizes were small, decreasing negative views on aging may help increase engagement of middle-aged and older people with social media. At the same time, fostering social media use could promote positive self-perceptions of aging.

People reflect on their own aging, and this subjective awareness has an influence on developmental outcomes. Scholars have recently operationalized subjective aging in terms of awareness of age-related change (AARC), which captures awareness of both gains and losses. We examined associations of AARC-gains and AARC-losses with physical functioning, subjective well-being, and engagement with life (enjoyable activities and sense of purpose). Importantly, we extended previous research by not only assessing main effects of gains and losses but also testing their interaction. We hypothesized that awareness of losses would be more weakly negatively associated with health and well-being among those who possessed higher awareness of gains. A total of 399 older participants aged 65 to 91 (235 women and 164 men) were recruited via Prime Panels crowd-sourcing platform to complete an online questionnaire. Greater AARC-losses was associated with poorer health, lower subjective well-being, and lower sense of purpose. AARC-gains was associated with better outcomes in general, and moderated associations of AARC-losses with physical functioning, subjective well-being, and sense of purpose (but not engagement in leisure activities). Consistent with predictions, moderation effects showed that negative associations of AARC-losses with the outcomes were weaker among those who reported higher AARC-gains. Results provided some support for a role of AARC-gains in buffering negative effects of AARC-losses on developmental outcomes.

Contemporary conceptualizations of mindfulness refer to paying attention to the present moment with an open and nonjudgmental attitude. Empirical research is increasingly focusing on mindfulness as a dynamic and multifaceted state that can fluctuate across situations and time. The present study aimed to extend existing knowledge by using experience-sampling methodology to examine state-level mindfulness, pleasant/unpleasant event occurrence, and affective well-being in the everyday lives of middle-aged and older adults. A community-based sample of 157 participants aged 53-86 (M = 69.36, SD = 5.80) was recruited in May-June 2020. Participants completed assessments of multidimensional state mindfulness, hassle and uplift occurrence, and positive and negative affect on their smartphones, four times a day over 10 consecutive days. (Total observations: 4,761; M = 30.32, SD = 8.78.) Multilevel models indicated that the state mindfulness-facets present-moment attention and nonjudgmental acceptance were predictive of greater affective well-being in older adulthood. Furthermore, nonjudgmental acceptance appeared to buffer affective reactivity to daily hassles, and importantly, this effect was stronger at older ages. Mindful states did not appear to provide any further boost to uplift-related mood. The findings suggest that occasions characterized by relatively high present-moment attention and nonjudgmental acceptance may contribute to enhanced emotional well-being in later adulthood. Furthermore, adopting a nonevaluative and accepting orientation toward momentary experiences may be a psychological strategy that has particular utility for mitigating emotional reactivity to daily stressors with increasing age. Future research should investigate multidimensional state mindfulness and affective well-being for middle-aged and older adults participating in mindfulness-based interventions.

Objectives Remaining engaged with life is a hallmark of aging well and pursuing personally meaningful activities is presumably important for late-life affect. We examined how moment-to-moment variability in meaning and degree of challenge ascribed to daily activities relate to positive and negative affect in very old adults. Possible moderating effects of between-person differences in conscientiousness on meaning-affect associations were also examined. Methods Participants were 73 adults aged 89 years on average from the Australian Daily Life Time-Sampling module of the Australian Longitudinal Study of Aging. Participants provided self-report data on activity engagement (meaning and challenge associated with activities) and affect, on 5 occasions per day for a period of 7 consecutive days. Results Within-person associations of activity meaning with affect varied as a function of within-person challenge ratings. Specifically, gains in positive affect associated with meaningful activity were more strongly evident when activities were regarded as more challenging. In contrast, meaningful activity was associated with higher negative affect when activities were regarded as more challenging and lower negative affect when activities were regarded as less challenging. Conscientiousness did not moderate associations of activity meaning with affect. Discussion Our findings shed light on the intricate interplay between maintaining meaningful engagement and daily emotional experiences in very old age. We discuss theoretical and practical implications and consider the role of late-life conscientiousness for self- and emotion regulation.

Background and Objectives Few studies have focused on the utility of mindfulness-meditation for well-being in older adults. The present study investigated the feasibility, acceptability, and preliminary efficacy of an app-based mindfulness-meditation program among older adults. Research Design and Methods A community-based sample of 46 participants aged between 63 and 81 (M = 70.85, SD = 4.70) engaged with a 30-day app-based mindfulness-meditation program for 10 min daily on their smartphones. Each meditation session comprised focusing on the breath, mentally scanning the body, monitoring the mind’s activity, and cultivating a nonjudgmental orientation toward experiences. Participants completed questionnaires at baseline, day 10, and day 30. Results On average, participants completed 25 sessions and almost 4 h of application use across the 30 days. Results of linear mixed effects models showed significant improvements in positive affect, negative affect, and life satisfaction across the study interval, but no meaningful change in total mindfulness or perceived stress. Furthermore, relative to high levels of smartphone efficacy, low smartphone efficacy was associated with higher perceived stress and negative affect, and less life satisfaction at baseline; and steeper improvements on these outcomes across the study interval. On average, older adults rated the app-based mindfulness-meditation training as interesting, enjoyable, valuable, and useful. Discussion and Implications The findings provide preliminary support for the feasibility and acceptability of an app-based mindfulness-meditation program with community-dwelling older adults and demonstrate potential benefits for well-being. Results suggest the value of further research investigating the efficacy of digital mindfulness-meditation interventions for older adults via larger randomized controlled trials.

This study examines how individuals (regulators) manage emotion in their social partners (targets) and whether the age of the regulator or the age of the target influences extrinsic emotion regulation strategy preference. An online questionnaire was used to assess extrinsic emotion regulation among 580 participants aged 18–87 years ( M = 50.04, SD = 18.13). Participants (regulators) indicated the extent to which they would be likely to use different strategies when interacting with a younger or older target who was upset. Results of multi-level modeling showed that older regulators endorsed less use of situation modification than younger regulators, but age differences in regulators’ use of other strategies were not significant. After adjustment for relationship-specific covariates, regulators endorsed less use of attentional deployment and cognitive change, for older targets than younger targets. Results are discussed in the context of lifespan perspectives on social behavior and emotion regulation.

How people adjust their goals is central to adaptation across the lifespan. However, little is known about individual difference characteristics that predict how and why people use different self-regulatory strategies. The present study investigated associations of perceived age-related gains and losses, and their interaction, as predictors of goal adjustment in older adulthood. Furthermore, we examined whether future time perspective (FTP) mediated relationships between awareness of age-related change (AARC) and goal adjustment.A community-based sample of 408 adults (aged 60-88 years) was recruited via an internet-based research platform. Participants completed questionnaire measures of AARC, FTP, goal disengagement, and goal re-engagement. A flexibility index reflecting tendencies toward use of both goal disengagement and goal re-engagement strategies was also analyzed.Although AARC-losses was associated with lower goal re-engagement and goal flexibility, this association was weaker among those with higher AARC-gains, indicating AARC-gains may be protective in the relationship between AARC-losses and goal adjustment. The association between AARC and goal adjustment was also shown to be mediated by FTP. Higher AARC-gains was associated with more expansive FTP, which was associated with lower goal disengagement and higher goal re-engagement. On the other hand, higher AARC-losses was associated with more restricted FTP, which was associated with higher goal disengagement and lower goal re-engagement.Results have implications for how we conceptualize the combined effects of age-related gains and losses on developmental outcomes relevant to adaptive aging. Furthermore, perceptions of future time with advancing age may be implicated in processes linking AARC with goal adjustment.

Objectives We aimed at examining between-person and within-person associations across age trajectories of perceptual speed and loneliness in old age. Method We applied multilevel models to 4 waves of data collected over 6 years from 1,491 participants of the Berlin Aging Study II (60–88 years at baseline, 50% women) to disentangle between-person and within-person associations across age trajectories of perceptual speed and both emotional and social loneliness. Sex and education were considered as relevant individual characteristics and included as covariates in the model. Results Analyses revealed that on average perceptual speed exhibited moderate within-person age-related declines, whereas facets of loneliness were rather stable. Perceptual speed did not predict age trajectories of emotional or social loneliness, at either the between- or within-person level. In contrast, loneliness discriminated individuals at the between-person level, such that those feeling emotionally or socially more lonely showed lower cognitive performance than those feeling emotionally or socially less lonely. Predictive effects of social loneliness were stronger for relatively young people (i.e., in their mid to late 60s) than for relatively older participants (i.e., in their 80s). In addition, predictive effects of social loneliness for perceptual speed at the within-person level were modest and deviated in direction and size from between-person social loneliness effects among those in their mid- to late 60s, whereas they did not among those in their 80s. Discussion We conclude that loneliness may serve as a precursor for basic cognitive functioning in old age and suggest routes for further inquiry.

Empirical research on the processes through which mindfulness affects well-being is in its infancy. Furthermore, few studies have considered the positive effects of mindfulness on psychological functioning from a lifespan perspective. The present study aimed to examine the role of age in moderating associations of mindfulness components with well-being in the context of a proposed model of mindfulness.A community-based sample of 623 participants aged between 18 and 86 years (Parallel mediation analyses showed that both present-moment attention and nonjudgment provided significant pathways to (a) flexible goal adjustment through nonattachment and decentering; and (b) well-being through acceptance, nonattachment, and decentering. Furthermore, present-moment attention, nonjudgment, acceptance, nonattachment, and decentering were all positively associated with age. Conditional process analyses revealed that the direct relationships between (1) present-moment attention and well-being, (2) nonjudgment and well-being, and (3) decentering and flexible goal adjustment became stronger with age and were significant for adults from around 40 years of age and older.The findings suggest that the tendency to focus on the present-moment and adopt a nonjudgmental orientation may become especially important for well-being with advancing age, and the ability to appreciate the transitory nature of personal experiences may be particularly important for flexible employment of both goal disengagement and reengagement strategies across the second half of life.

The empirical evidence concerned with the centrality of social relations to individual functioning across adulthood continues to accumulate. Theoretical development about age-related changes in social relationships, however, has lagged behind. In particular, existing theories either do not account for the influence of the developmental context, or are difficult to examine empirically because they do not posit specific testable mechanisms. We present a new conceptual model that we believe effectively incorporates much of the existing empirical work. The Differential Investment of Resources (DIRe) model has five distinct features. First, the model distinguishes between different types of ‘social ties’ by defining two crucial dimensions - closeness and kinship. Second, the investment of time and energy is defined as the core mechanism that explains the formation and maintenance of social ties. Third, individual characteristics, categorized as capacities, motivations, and skills, determine the amount, direction, and efficacy of the time and energy invested. Fourth, the model incorporates the developmental context: (a) in its effect on the social opportunity structure; (b) in its effect on time and energy; and (c) in its effect on the individual. Additionally, the social opportunity structure itself is determined by the individual’s existing social network ties (i.e., social capital). Finally, the model describes how different types of ties, in turn, affect individual characteristics via social functions (social exchanges, social evaluations, and social influences). The proposed model will not only stimulate a healthy new debate in the field, but will also provide a theoretical basis for future research and hypothesis-testing.

How people manage their goals is central to adaptation across the lifespan. However, little is known about the individual difference characteristics that predict how and why people use different self-regulatory strategies. The present study aimed to investigate associations of perceived age-related gains and losses, and their interaction, as predictors of flexibility in goal management in older adulthood. We also examined whether future time perspective (FTP) mediated the relationship between AARC and goal flexibility, such that awareness of aging impacts perceptions of time remaining, impacting how individuals evaluate and manage their goals. A community-based sample of 408 adults aged between 60 and 88 years was recruited via an internet-based research platform. Participants completed questionnaire measures of AARC-gains, AARC-losses, FTP, goal disengagement, and goal re-engagement. A flexibility index reflecting tendencies toward use of both goal disengagement and re-engagement strategies was also analyzed. Although AARC-losses was associated with lower goal re-engagement and goal flexibility, this association was weaker among those with higher AARC-gains, indicating that AARC-gains may be protective in the relationship between AARC-losses and goal management. Furthermore, the association between AARC and goal management was mediated by FTP. Higher AARC-gains were associated with more open-ended FTP, which was associated with higher goal re-engagement and lower goal disengagement. On the other hand, higher AARC-losses was associated with more restricted FTP, which was associated with lower goal re-engagement, and higher goal disengagement. Results suggest that subjective awareness of aging (particularly awareness of gains), has important implications for goal management in older adulthood.

Historically, family ties have been understood as the primary source of support for aging adults, and past empirical and theoretical work has highlighted the tendency of older adults to focus on close family. However, in line with demographic changes and historical increases in the diversity of social structures, friendships are increasing in importance in recent generations of older adults. Given the powerful role of context in shaping these changes, this paper offers a conceptual analysis linking individual agency to sociohistorical context as a way to understand this increasing diversity of social ties. More specifically, we propose that the individual invests time and energy to form and maintain social ties, and that each individual has a specific social opportunity structure (all potential ties that are available to invest in, as well as the costs of those investments). Furthermore, this investment of time and energy is determined in part by individual differences in capacities and motivations. We argue that sociohistorical context influences this process in three important ways: (1) in its effect on the social opportunity structure; (2) in its direct effect on time and energy; and (3) in its effect on individuals’ capacities and motivations. We believe that these mechanisms can account for the increasing diversity of social ties across adulthood, as well as the potential for future historical changes.

Background: Long-term protective associations proposed between previous complex occupational tasks and cognitive functioning in later life point to work roles contributing to cognitive reserve. Objective: To examine occupational complexity involving data, people, and things in relation to the level of, and rate of change in, cognitive functioning. Methods: Participants were 1,290 members of the Australian Longitudinal Study of Ageing and initially aged 65-102 years (mean = 79). Information about main lifetime occupation was collected retrospectively. Cognition was assessed 4 times over a 13-year interval. Results: In multilevel models adjusted for demographics, medical conditions, and depressive symptoms, higher complexity involving data was associated with faster speed (β = 0.73, p < 0.001), better memory (β = 0.32, p < 0.05), and mental status (β = 0.40, p < 0.001) at baseline. These associations remained statistically reliable after adjusting for complexity with people and things, sedentary and heavy physical work, retirement age, and leisure activity. Complexity with things was associated with slower speed (β = -0.50, p < 0.001) and poorer mental status (β = -0.26, p < 0.01) and was not explained by other variables. There were no associations of occupational complexity with rates of cognitive decline over time. Conclusion: Older individuals retired from occupations characterized by higher complexity with data maintain their cognitive advantage over those with lower complexity into older adulthood, although without additional moderation of this advantage in terms of less postretirement cognitive decline. Complexity of work with things confers a negative relation to cognition whilst also not affecting postretirement cognitive change. Although the relative contributions of occupation or other early life influences for cognition remain to be established, it nevertheless may be beneficial to promote workplace design strategies and interventions that incorporate complex activities, particularly tasks involving data.

Few studies have focused on the utility of mindfulness-meditation for well-being in older adults. This study aimed to investigate the feasibility and acceptability of an app-based mindfulness-meditation program for community-based older adults. A convenience sample of 46 participants aged between 63 and 81 (M = 70.85, SD = 4.70) was recruited from the community. Participants were invited to engage with a 30-day app-based mindfulness-meditation program for 10-minutes daily on their smartphones. Each meditation session comprised focusing on the breath, mentally scanning the body, monitoring the mind’s activity, and cultivating a nonjudgmental attitude toward experience. Participants completed psychosocial questionnaires at baseline, day 10, and day 30. On average, participants completed 25 sessions and almost 4 hours of application use across the 30-days. Results of linear mixed effects models showed significant improvements in positive affect, negative affect, and life satisfaction across the study interval, but no meaningful change in total or facet-level mindfulness or perceived stress. Furthermore, relative to high levels of smartphone efficacy, low smartphone efficacy was associated with higher perceived stress and negative affect, and less life satisfaction at baseline; and steeper improvements on these outcomes across the study interval. Results indicated that, on average, older adults found app-based mindfulness-meditation training interesting, enjoyable, valuable, and useful. The findings provide preliminary support for the feasibility and acceptability of an app-based mindfulness-meditation program with community-based older adults and demonstrate potential benefits for well-being. Furthermore, older adults’ perceptions of smartphone competency may play an important role in the outcomes of app-based programs.

Objectives: Activity participation is associated with a range of positive outcomes in older adults but tends to decline with age. Understanding protective factors is important to facilitate activity in later life. Social cognitive theory suggests that having high self-efficacy may promote activity because individuals with higher self-efficacy perceived their activities to be easier and use adaptive strategies to overcome barriers to activity. Despite considerable research linking self-efficacy and activity, limited research has examined the proposed mechanisms behind this association. This study therefore examined whether perceived ease of activity and use of adaptive strategies account for the association between self-efficacy and activity. Method: Participants were 412 adults aged 50–93 years who completed a cross-sectional survey.Structural equation modelling was used to examine whether the effects of self-efficacy on activity were mediated by perceived ease of activity and use of adaptive strategies Results: Perceived ease of activity mediated the positive associations between self-efficacy and social (0.04 [0.02, 0.07]) and physical activity (0.16 [0.08, 0.25]), but not mental activity (0.01 [0.000,0.03]). For physical activity, this effect was stronger for adults aged 70+ years than those aged 50–69 years (older a₂*b₂ - younger a₂*b₂ 0.13 [0.04, 0.24]). Use of adaptive strategies was not a significant mediator in any model. Conclusion: This study suggests that self-efficacy may influence older adults’ perception of activities and, in turn, the activities they choose to participate in. This has potential implications for the development of interventions aimed at promoting activity engagement in later life. Refereed/Peer-reviewed

Research examining how mindfulness confers benefits for well-being is in its infancy. Furthermore, few studies have considered the positive effects of mindfulness on psychological functioning from a lifespan perspective. The present study aimed to examine a recently proposed model of mindfulness and whether the importance of the proposed mechanisms for well-being varied as a function of age. A community-based sample of 623 participants aged between 18 and 86 years (M = 48.78, SD = 16.74) was recruited via an internet-based research platform. Participants completed questionnaire measures of mindful characteristics (i.e., present-moment attention, nonjudgment, interoception, acceptance, nonattachment, and decentering), flexible goal adjustment, and well-being. Parallel mediation analyses using bootstrapping showed that both present-moment attention and nonjudgment provided significant pathways to (a) well-being through acceptance, nonattachment, and decentering; and (b) flexible goal adjustment through nonattachment and decentering. Furthermore, most aspects of mindfulness were positively associated with age. Conditional process analyses revealed that the direct relationships between (1) present-moment attention and well-being, (2) nonjudgment and well-being, and (3) decentering and flexible goal adjustment were significant for adults from around age 40 and became stronger with increasing age. The findings provide preliminary support for a recently proposed model of mindfulness and suggest that present-moment attention, nonjudgment, and decentering may become especially important for well-being across the second half of life. In particular, these aspects of mindfulness may represent psychological qualities that require a relatively modest investment of physiological and cognitive resources and can be targeted in interventions designed to enhance well-being in later adulthood.

Having a sense of purpose is recognized as an important resource for maintaining health and well-being over the life span. We examined associations of individual differences in sense of purpose with levels and rates of change in indices of aging well (health, cognition, and depressive symptoms) in a sample of 1,475 older adults (M-age = 77.06 years, SD = 6.27; 50% female) assessed on up to 6 occasions over 18 years. We also conducted survival analysis to examine associations of purpose with longevity. We hypothesized that a higher sense of purpose would be associated with better performance on the aging well measures, and that those with a higher sense of purpose would show shallower declines in aging well over time. Results indicated that participants who scored higher on sense of purpose reported lower levels of functional disability, performed better on cognitive tests (episodic memory and speed of processing), and reported better self-rated health and fewer depressive symptoms. Sense of purpose was not associated with individual differences in rates of change in the aging well indices with the exception of speed of processing, for which a higher sense of purpose was associated with marginally shallower rates of decline. Higher sense of purpose was also associated with increased probability of survival, although this association became weaker over time. The findings support the notion that purposeful living contributes to health and well-being. At the same time, higher sense of purpose may not buffer against more pervasive losses in health that become more common in oldest-old adulthood. Refereed/Peer-reviewed

This review examines differences in the use of emotion regulation (ER) strategies among younger and older adults.A systematic review using search terms related to ageing and ER identified 23 relevant studies. Narrative synthesis was adopted to analyse the findings.Generally, greater use of situation selection and attentional deployment was identified among older adults, although these relationships were dependent on contextual/moderator variables. While older adults employed greater levels of situation modification in response to negative stimuli, there was considerable variation in age differences across specific situation modification subtypes. Available evidence pointed to an absence of age differences in the cognitive change strategy of cognitive reappraisal. The use of relatively less-cognitively demanding cognitive change subtypes (e.g. acceptance) was, under particular circumstances, greater among older adults. Findings regarding the response modulation strategy of expressive suppression were equivocal.Adult development is not characterised by straightforward shifts in preferences for use of different ER strategies. Moderator variables appear to be of central importance in shaping the emergence of age differences in ER. Systematically examining interactions of age with individual difference variables and situational factors in samples including oldest-old adults will be important for advancing knowledge regarding developmental differences in ER.

Socio-emotional theories suggest that with age, hedonic goals are increasingly prioritised, with changes in social motivation and emotion regulation (ER) strategies proposed as mechanisms facilitating pursuit of such goals. Supportive relationships and ER strategies such as reappraisal are thought to buffer against the negative affective consequences of stress. Personality traits such as neuroticism and extraversion also affect stress and negative affect. Few studies have used intensive longitudinal data to examine the role of psycho-social variables as moderators of associations of stress and negative affect and how these relationships differ with age. To bridge this gap in existing research, a micro-longitudinal design was employed in which 38 younger (aged 17–28) and 44 older (aged 62 and over) adults completed measures of personality, positive and negative social exchanges, and habitual ER (i.e., reappraisal and suppression) at baseline assessment, and measures concerned with daily experiences of stress and negative affect over 20 consecutive days. Analysis of between-person associations indicated that those with higher levels of reappraisal and positive social exchanges showed a weaker association between levels of stress exposure and negative affect. Higher extraversion buffered the association of stress and negative affect, while higher levels of neuroticism and more frequent negative social exchanges amplified between-person stress-negative affect associations among older adults. Higher reappraisal and lower neuroticism were each associated with reduced reactivity to stress at the within-person level for older adults. The results highlight age differences in the significance of psycho-social resources for protecting against deleterious effects of daily stress exposure.

We examined how positive and negative social exchanges with friends, family, and spouses were related to cognitive aging in episodic and working memory, and perceptual speed. To do so, we used a large sample of cognitively intact young-old participants from the PATH Through Life Study (PATH; aged 60 to 64 years at baseline, n = 1,618) who were assessed on 3 occasions over 8 years. Additional replication analyses were conducted using the Health and Retirement Study (HRS), which provided data on episodic memory. The main analysis of PATH Through Life showed that positive exchanges with friends and family were associated with less decline in perceptual speed, with these associations attenuated by adjustment for physical functioning and depressive symptoms. Negative exchanges with spouses were associated with poorer working memory performance. Positive exchanges with friends were associated with better initial episodic memory in both PATH and HRS. More frequent negative exchanges with friends and family were associated with better episodic memory in the PATH sample. However, these findings were not replicated in HRS. Our findings provide indirect support for the role of social exchange quality in contributing to cognitive enrichment. However, the inconsistent pattern of results across cognitive and social exchange domains points to possibilities of reverse causality, and may also indicate that social exchange quality plays a less important role for cognitive enrichment than other psychosocial characteristics.

Participation in meaningful activities may be particularly important for late life well-being. We examined associations of moment to moment variability in meaningful activity engagement with positive and negative affect in the daily lives of oldest-old adults. Moderating effects of conscientiousness on meaning-affect associations were also examined considering recent theorising that late life declines in conscientiousness could reflect adaptive self-regulatory processes. Participants were 73 adults aged 84 and above from the Australian Longitudinal Study of Aging Daily Life Time-Sampling (ADuLTS) study, who provided self-report data on activity engagement (including ratings of meaning and degree of challenge associated with activities) and affect on five occasions per day over seven days. Within-person variability in meaningful activity engagement was associated with positive and negative affect; however, these associations were conditional upon the extent to which activities were rated as challenging. Specifically, positive affect tended to be lower on occasions when activities were rated as less meaningful, but also more challenging. Similarly, negative affect was rated as lower on occasions when activities were regarded as more meaningful, and at the same time less challenging. Participants who were higher in conscientiousness reported higher overall positive affect, and associations of higher conscientiousness with lower momentary negative affect were evident on occasions when activities were rated as more challenging. Engagement in meaningful activity is associated with higher positive, and lower negative affect in late life, with these associations dependent on the extent to which activities are challenging. Findings are discussed in the context of self-regulatory perspectives on adaptation.

Objectives: Research has shown that functional limitation is related to reduced social activity in older adults; however, individuals with high perceived control have greater confidence in their ability to achieve outcomes and are more likely to show persistence and employ strategies to overcome challenges. The aim of this study was to examine whether perceived control protects against the negative effects of functional limitation on older adults’ social activity. Method: Participants were 835 older adults aged 69 to 103 years at baseline from the Australian Longitudinal Study of Ageing. Multilevel modeling was used to examine baseline and within-person change in functional limitation and perceived control as predictors of 18-year trajectories of social activity. Results: An interaction between baseline functional limitation and perceived control indicated that having greater functional limitation was associated with less social activity and greater decline over time for those with lower perceived control, but not for those with higher control. Within-person change in functional limitation was not reliably associated with social activity. Discussion: This study highlights the importance of perceived control as a protective psychological resource and may have implications for developing interventions aimed at enabling older adults to maintain their social activity as they experience functional decline.

Over the past two decades, research in lifespan developmental psychology has identified normative changes in social and emotional functioning that occur throughout adulthood. With its grounding in the interpersonal realm, and a focus on processes of adaptation and emotional experience, self-forgiveness represents a construct of direct relevance to socio-emotional aging. Despite this, relatively few studies have examined associations of self-forgiveness with age. This chapter provides an overview of the existing empirical literature concerned with aging and self-forgiveness and offers a lifespan perspective by integrating conceptual models of self-forgiveness with lifespan developmental theory and research on motivation, self- and emotion-regulation. The chapter concludes with an outline of how accrued interpersonal experience, shifts in motivation, and changing resource profiles with aging could each impact on the nature of self-forgiveness in later life. Directions for future research and implications for clinical practice are discussed.

Background: Participation in activities is associated with a range of positive outcomes in adulthood. Research has shown that pain and physical symptoms are associated with less activity in older adults, whereas higher self-efficacy is associated with more activity. Such research tends to examine cross-sectional or long-term between-person change, limiting the opportunity to explore dynamic within-person processes that unfold over shorter time periods. Objectives: This study aimed to (1) replicate previous between-person associations of self-efficacy with engagement in activity and (2) examine whether daily variation in pain, physical symptoms, and self-efficacy corresponded with daily within-person variation in different types of activity. We predicted that participants would engage in less activity on days when they experienced more pain or physical symptoms than their average (a negative within-person association) and that participants would engage in more activity on days when self-efficacy was higher than average (a positive within-person association). Methods: This study used an online diary study to assess self- reported daily pain, physical symptoms, self-efficacy, and engagement in activity among 185 adults aged 51-84 years for up to 7 days. Multilevel modelling was used to examine whether between-person (average) and daily within-person variability in pain, physical symptoms, and self-efficacy were associated with social, physical, and mental activity. Results: In line with previous research, between-person self-efficacy was positively associated with social and physical activity. Supporting the hypotheses, within-person self-efficacy was also positively associated with social and physical activity. The results for pain and physical symptoms were less consistent. Between-person pain was positively associated with social activity. Age interactions indicated that within-person pain was negatively associated with social activity and positively associated with physical activity among older adults. Within-person physical symptoms were positively related to social and mental activity. Conclusion: Stable individual differences as well as short-term within-person variation in physical and psychological functioning are associated with day-to-day variation in activity. Between-person associations did not always reflect within-person associations (e.g., for pain). These complex associations may be influenced by a range of factors including the type of activity and how it is defined (e.g., specific activities and their difficulty), the type of physical symptoms experienced, and age.

An increasing number of studies point to normative changes in personality occurring during adulthood. We examined age group differences and longitudinal changes in approach-avoidance sensitivities across adulthood using a population-based sample of younger, midlife, and older adults (N = 7468) assessed on three occasions over an 8 year interval. Younger adults reported higher approach sensitivity (assessed using BAS-Drive and BAS-Reward subscales) relative to midlife and older adults. Approach sensitivity tended to decline between Times 1 and 3 for all age groups. Cross-sectional age differences were not evident for avoidance sensitivity at Time 1 (assessed using the BIS); however there was evidence for different patterns of change in avoidance over time across the age groups. Results are discussed in the context of lifespan developmental perspectives on self-regulation of emotion and behaviour. Refereed/Peer-reviewed

AIMS: (1) To identify factors that older adults find encouraging or discouraging about the prospect of relocation to a retirement village; and (2) to identify features or facilities often associated with retirement communities that are most appealing to prospective residents. METHOD: Randomly selected community residents (n = 517), aged 55-94 years, from the Australian Capital Territory completed postal surveys to identify the characteristics associated with retirement villages that influence relocation decisions. RESULTS: The provision of outdoor living areas, support in maintaining independence, assisted living facilities and accessibility to medical facilities were identified as factors that would encourage relocation. Luxury services (e.g. heated swimming pools) were indicated as least likely to encourage relocation. Negative perceptions most influential in discouraging relocation reflected a fear of losing independence and privacy. CONCLUSIONS: Through identifying the expectations of prospective residents, retirement village providers may better tailor facilities to the needs of their target demographic. Language: en

Background: Findings from existing research exploring whether positive social exchanges can help to offset (or ‘buffer’ against) the harmful effects of negative social exchanges on mental health have been inconsistent. This could be because the existing research is characterized by different approaches to studying various contexts of ‘cross-domain’ and ‘within-domain’ buffering, and/or because the nature of buffering effects varies according to sociodemographic characteristics that underlie different aspects of social network structure and function. Objective: The purpose of this study was to examine whether the buffering effects of global perceptions of positive exchanges on the link between global negative exchanges and mental health varied as a function of age and gender. Method: We used a series of regressions in a sample of 556 Australian older adults (ages 55–94) to test for three-way interactions among gender, positive social exchanges, and negative social exchanges, as well as age and positive and negative social exchanges, in predicting mental health, controlling for years of education, partner status, and physical functioning. Results: We found that positive exchanges buffered against negative exchanges for younger old adults, but not for older old adults, and for women, but not for men. Conclusions: Our findings are interpreted in light of research on individual differences in coping responses and interpersonal goals among late middle-aged and older adults. Our findings are in line with gerontological theories (e.g. socioemotional selectivity theory), and imply that an intervention aimed at using positive social exchanges as a means of coping with negative social exchanges might be more successful among particular populations (i.e. women, ‘younger’ old adults).

Purpose: Interest in evaluating purpose in life as an important component of ageing well is growing; however, investigation into the appropriate measurement of this construct is required. The purpose of this paper was to examine the measurement properties of the Life Engagement Test (LET) and to provide normative data for a nonclinical sample of community-dwelling older adults. Methods A random sample of 545 adults, aged 55- Methods: A random sample of 545 adults, aged 55-94 years, completed the LET twice over a 12-month period as part of a larger survey on relocation in later life. Results: Consistent with previous research, participants typically reported high levels of purpose in life. Scores were also observed to vary over the 12-month duration, with, on average, an increase in purpose in life at Time 2. However, tests of longitudinal invariance were inconclusive. Conclusions: Future research is needed to further examine the content validity of the LET, and its factorial invariance over longer measurement intervals, and across different populations including non-residential/aged care settings.

Objectives Aging-related changes in motivation and the availability of resources have been hypothesized to result in social network changes in later life. However, few studies have examined associations of both motivation and resources with different aspects of social network composition in the same analytical context. The present study examined associations of key motivational (future time perspective [FTP]) and resource variables (partner status, physical health, and perceived neighborhood cohesion) with social network size and positive and negative social exchanges. Method A population-based sample of midlife (aged 55-59 years, n = 169) young-old (aged 60-74 years, n = 306) and old-old (aged 75+ years, n = 77) adults completed a questionnaire. Results Those who were partnered reported larger networks with family, whereas never-married individuals reported larger networks with neighbors. Perceived neighborhood cohesion was related to larger networks with family, neighbors, and friends. Open-ended FTP was associated with larger networks of friends and more frequent positive social exchanges. Discussion Our results point to FTP and resources having different implications for social engagement across network domains.

Objectives. The aim of this study w as to examine age differences in high- and low-arousal positive and negative affect, and associations of physical functioning with affect over the latter half of the life course. Method. P articipants consisted of 39,958 midlife and older adults contributing to DYNOPTA; a large-scale collaborative project concerned with pooling data from Australian studies of aging. Items assessing the experience of discrete emotions were selected to represent different combinations of high- and low-arousal affect, and positive and negative valence affect. Results. Older adults were more likely to endorse low-arousal positive affect, and less likely to endorse negative affect (both high and low arousal) relative to those in midlife. Better self-reported physical functioning was associated with younger age, higher positive, and lower negative affect, with physical functioning emerging as a suppressor of associations of age with affect in regression analyses. Conclusions. The results, based on a v ery large sample of older adults, are consistent with those of other studies demonstrating lower levels of negative emotion among older, relative to midlife adults. The findings also highlight the relevance of physical functioning to emotional well-being over the latter part of the life course.

Objective. This study examined the extent to which associations between volunteering and subjective well-being (SWB) could be related to volunteers having more supportive social networks relative to nonvolunteers. Method. The sample consisted of 561 midlife and older adults (aged 55–94 years) from the TRAnsitions In Later Life study. Multiple mediation analyses examined associations between hours spent volunteering per week; availability of social support from friends, relatives, and neighbors; positive and negative social exchanges; and SWB. Results. The results indicated that the higher life satisfaction and positive affect reported by those who volunteer at moderate levels (up to 7 hr per week) are related to their higher levels of positive social exchanges and greater availability of social support from friends and family, relative to nonvolunteers. Those who volunteer at higher levels (7 hr or more per week) also reported greater levels of positive affect in comparison to nonvolunteers, and this was related to their greater availability of social support from friends. Availability of support from friends accounted for the greatest proportion of the volunteering–SWB associations. Discussion. The findings suggest that the positive SWB associated with volunteering is related to volunteers’ more

It is unclear whether the longitudinal relation between activity participation and cognitive ability is due to preserved differentiation (active individuals have higher initial levels of cognitive ability), or differential preservation (active individuals show less negative change across time). This distinction has never been evaluated after dividing time-varying activity into its two sources of variation: between-person and within-person variability. Further, few studies have investigated how the association between activity participation and cognitive ability may differ from early to older adulthood. Using the PATH Through Life Project, we evaluated whether between- and within-person variation in activity participation was associated with cognitive ability and change within cohorts aged 20-24 years, 40-44 years, and 60-64 years at baseline (n = 7,152) assessed on three occasions over an 8-year interval. Multilevel models indicated that between-person differences in activity significantly predicted baseline cognitive ability for all age cohorts and for each assessed cognitive domain (perceptual speed, short-term memory, working memory, episodic memory, and vocabulary), even after accounting for sex, education, occupational status, and physical and mental health. In each case, greater average participation was associated with higher baseline cognitive ability. However, the size of the relationship involving average activity participation and baseline cognitive ability did not differ across adulthood. Between-person activity and within-person variation in activity level were both not significantly associated with change in cognitive test performance. Results suggest that activity participation is indeed related to cognitive ability across adulthood, but only in relation to the starting value of cognitive ability, and not change over time.

Leading an engaged lifestyle is recognised as one means of contributing to cognitive health across adulthood. This has led to several studies examining associations of social network attributes with cognition in older adults. Most have focused on structural aspects of networks (e.g., network size and activity engagement), however social networks are multi-faceted and different aspects of social behaviour could affect cognition through different mechanisms. This study used data from the Berlin Aging Study (BASE), a population-based study of 516 adults (age range 70 – 103) to examine associations of baseline social network structure (number of close others, network members lost through death), and network quality (social and emotional loneliness, number of upsetting network members) with levels and rates of change in processing speed and verbal fluency. Number of close others, and number of network members lost were not associated with levels, or rates of decline in speed or fluency across the 13 year study interval. Among the network quality indicators, greater social and emotional loneliness were each related to poorer levels of cognitive performance, but were unrelated to rates of change. Having a greater number of problematic network members was associated with higher levels of fluency. The discussion focuses on the different mechanisms through which social functioning could affect cognition, and considers issues of possible reciprocal causation.

This study provides much needed information on the education level of older drivers regarding the impact of health conditions and medications on personal driving safety, where they source this information, and how this knowledge influences self-regulation of driving. Random and convenience sampling secured 322 Australian drivers (63.9% males) aged 65 years and over (M = 77.35 years, SD = 7.35) who completed a telephone interview. The majority of respondents (86%) had good knowledge about health conditions (health knowledge) and driving safety, however more than 50% was classified as having poor knowledge on the effects of certain medications (medication knowledge) and driving safety. Poorer health knowledge was associated with a reduced likelihood of driving over 100 km in adjusted models. Being older and having more than one medical condition was found to increase the likelihood of self-regulation of driving. Results indicate that health knowledge was less important for predicting driving behaviour than health experience. Of great interest was that up to 85.7% of respondents reported not receiving advice about the potential impact of their medical condition and driving from their doctor. The findings indicate a need for improved dissemination of evidence-based health information and education for older drivers and their doctors.

Objective: The tripartite model of depression and anxiety hypothesizes that positive and negative affect is related to depression and anxiety. However, the specific role of cognitive or psychological well-being constructs like resilience and mastery within a tripartite context and throughout adulthood is unclear. Method: Data was drawn from two longitudinal population-based cohorts, aged 20–24 and 40–44 based in Canberra, Australia (N = 3989). We sought to determine the interrelatedness of two affective measures of subjective well-being, positive and negative affect, with two cognitive measures of psychological well-being, resilience and mastery. We then tested their independent effects on depression and anxiety, and hypothesized, following the tripartite model, that subjective well-being would mediate the effects of the psychological well-being variables on mental health and that the psychological well-being variables would be more strongly related to positive subjective well-being. Results: Principal axis factoring delineated four affective and cognitive dimensions of well-being comprising positive and negative affect, resilience and mastery. Structural equation models identified the psychological well-being variables as significantly related to subjective well-being, which fully mediated the effects of resilience and partially mediated the effect of mastery on depression and anxiety. These findings were consistent throughout both young and middle adulthood. Conclusions: Psychological well-being components are significant predictors of subjective well-being affect states that increase vulnerability to depression and anxiety.

Background: Despite the increasing utilization of formal services by older adults in many nations, there is a paucity of research that has examined the relationships between disability, formal support and depressive symptoms in later life. Objective: We investigated whether support received for daily activities, either from formal and/or informal sources, weakened the deleterious relationship between disability and depression symptoms in later life and whether these stress-buffering effects were stronger in later years of older adulthood. Methods: Participants were 1,359 community-dwelling older adults drawn from Wave 1 of the Australian Longitudinal Study of Ageing. Hierarchical multiple regression was used. Results: Individuals receiving support from (1) informal sources only and (2) both informal and formal sources had weaker relationships between disability and depressive symptoms, relative to those receiving no support. The interaction between informal and formal support and disability also revealed that for individuals with above average functional limitations, receipt of this support type was associated with fewer depressive symptoms. However, for individuals with no functional limitations, receipt of both informal and formal support was not associated with depressive symptoms. The stress-buffer age variation hypothesis received no support. Conclusions: Findings suggest that receiving a combination of informal and formal support may be sufficient to offset the harmful association between disability and depressive symptoms in later life. In addition, findings further emphasized the importance of informal support in later life. In contrast, formal support in isolation may not be sufficient to confer a protective effect. Given the expected increase in utilization of formal services among older adults in the coming decades, it is essential that future research investigates the possible factors that underlie this null result.

Aims: The aim of this paper is to investigate two possible explanations for the higher levels of psychological distress observed among alcohol abstainers relative to light and moderate drinkers, and to investigate possible moderating effects of age on this association. The possible explanations were that: (i) the higher level of psychological distress among abstainers is due to the presence of a subset of former heavy drinkers in this group; and (ii) abstainers have poorer social relationships than light/moderate drinkers. Methods: A national cross-sectional survey yielded data from 2856 Australians aged 20-22, 30-32 and 40-42 years (response rate 15.9%). Results: The sample was representative for many socio-demographic factors but under-represented people not in the labour force and over-represented those with university qualifications. In the oldest but not the younger age groups, abstainers reported sig- nificantly higher psychological distress relative to light/moderate drinkers. While abstainers in the oldest age group who were former heavy drinkers showed the highest levels of distress, excluding them from the analysis did not account for differences in distress between current abstainers and light/moderate drinkers. Abstainers aged 40-42 years were less socially integrated, less extraverted and had lower social support than light/moderate drinkers, and controlling for these factors partially explained their increased distress. Conclusions: Significantly increased psychological distress of abstainers compared to light/moderate drinkers was demonstrated only in the oldest age group (40-42 years). The higher distress reported by abstainers in this age group was partially explained by abstainers having poorer social relationships than light/moderate drinkers.

OBJECTIVES: To investigate self-reported driving status within three Australian states; associations between demographic, health, and functional factors and driving status; and the extent to which remaining a driver in spite of cognitive and visual impairments varies as a function of sex. DESIGN: Secondary data analysis of a pooled data set. SETTING: Australian communities. PARTICIPANTS: Adults aged 65 to 103 (N=5,206) from the Dynamic Analyses to Optimise Ageing (DYNOPTA) project. DYNOPTA is a unique data set created through the harmonization and pooling of data across nine separate Australian longitudinal studies of aging conducted between 1990 and 2007 (N=50,652). MEASUREMENTS: Driving status, demographic characteristics, Mini-Mental State Examination score, visual acuity, physical activity, and occupation. RESULTS: Men and participants with higher-level occupations had greater odds of driving. Older age, more medical conditions, and poorer vision increased the odds of not driving. Persons who were divorced, widowed, or never married were at a greater risk than married adults of not driving. Descriptive analyses revealed a large proportion of men with probable visual or cognitive impairments who reported driving. Subsequent comparative analyses between the DYNOPTA sample and other published U.S. and Canadian data revealed lower proportions of current drivers among Australian women and those at older ages, although there were consistently lower proportions of drivers within Australia and Canada than in the United States. CONCLUSION: The rate of men with probable dementia or visual impairments who reported driving is of particular concern. Research and policy need to focus on evidence-based assessment of older drivers and development of appropriate interventions and programs to maintain the mobility and independence of older adults.

There is a strong association between financial hardship and the experience of depression. Previous longitudinal research differs in whether this association is viewed as a contemporaneous relationship between depression and hardship or whether hardship has a role in the maintenance of existing depression. In this study we investigate the association between depression and hardship over time and seek to resolve these contradictory perspectives. We also investigate the consistency of the association across the lifecourse. This study reports analysis of two waves of data from a large community survey conducted in the city of Canberra and the surrounding region in south-east Australia. The PATH Through Life Study used a narrow-cohort design, with 6715 respondents representing three birth cohorts (1975-1979; 1956-1960; and 1937-1941) assessed on the two measurement occasions (4 years apart). Depression was measured using the Goldberg Depression Scale and hardship assessed by items measuring aspects of deprivation due to lack of resources. A range of measures of socio-economic circumstance and demographic characteristics were included in logistic regression models to predict wave 2 depression. The results showed that current financial hardship was strongly and independently associated with depression, above the effects of other measures of socio-economic position and demographic characteristics. In contrast, the effect of prior financial difficulty was explained by baseline depression symptoms. There were no reliable cohort differences in the association between hardship and depression having controlled for socio-demographic characteristics. There was some evidence that current hardship was more strongly associated with depression for those who were not classified as depressed at baseline than for those identified with depression at baseline. The evidence of the contemporaneous association between hardship and depression suggests that addressing deprivation may be an effective strategy to moderate socio-economic inequalities in mental health.

Longitudinal associations between generalized control beliefs (one's perceived capacity to influence events) and cognitive test performance were examined in a population-based sample of young, midlife and older adults. Participants provided measures of perceived control, self-assessed health, education and depression and anxiety symptoms, and completed cognitive tests at two assessments, 4 years apart. For each age group, baseline (between-person) control was positively related to performance on tests of memory (immediate recall and digits backwards), speed (Symbol Digit Modalities Test and choice reaction time) and verbal intelligence (Spot-the-Word). Interaction effects indicated stronger associations of between-person control beliefs with indices of speed for the older age group relative to the younger groups. Within-person changes in control were not significantly associated with changes in cognitive test performance over the study interval. Implications of the findings for self-efficacy based interventions designed to promote cognitive functioning are discussed.

A strong sense of control over the environment is an important component of well-being and promotes resilience to stress. This paper reports a longitudinal investigation of associations between negative life events in midlife, approach–avoidance aspects of personality, and control beliefs in a population-based sample of midlife adults. Results indicated that the experience of negative life events was associated with weaker control beliefs. Behavioral approach was positively related to control, and may be protective against negative life events undermining control beliefs, for those low in behavioral inhibition. Behavioral inhibition was associated with lower control beliefs. Implications for promoting adaptive self-regulation are discussed.

We used responses from telephone interviews conducted with a community sample of 304 older drivers to investigate associations between perceived control over driving, driving ability perception (an index of unrealistic optimism), and self-reported avoidance of high-risk driving situations. We also investigated associations between perceived control over driving, ability perception, and indices of well-being (life satisfaction and depressive symptoms). Our results indicated that perceived control and perceived ability were each associated with reduced risk avoidance and well-being, with these associations moderated by gender. We discuss the results in terms of potentially adaptive and maladaptive consequences of pervasive perceptual biases, gender differences in primary and secondary control strategies, and the importance of effective self-regulation for aging well.

Objective: To demonstrate the value of comparing data from multiple cohort studies using the example of self-rated health (SRH). Methods: Seven Australian cohort studies including comparable data on SRH were identified. Comparisons of the distributions of SRH were conducted, and logistic regression was used to evaluate age, sex and education effects within studies. A nationally representative survey was used as a statistical reference to determine how studies differed from the Australian population in frequencies of responses. Results: Ratings of SRH declined with increasing age. Low education was associated with higher frequencies of fair/poor SRH even in young adulthood but there were no sex differences. Results for smaller studies did not necessarily differ from nationally representative studies. Conclusion: Collaborative reanalysis of Australian cohort permits analysis of health outcomes from a large numbers of participants. Health outcomes and their sociodemographic determinants may be more comprehensively evaluated through such collaborative projects.

Objective The objective of this study was to determine the association between weekly alcohol consumption and brain atrophy in adults aged 60 to 64 years. Methods Brain magnetic resonance imaging scans from 385 adults recruited through a community survey were analyzed. Automated segmentation and manual tracing methods were used to obtain brain subvolumes and automated methods were used to obtain quantification and localization of white matter hyperintensities. Visual measures of cortical atrophy were obtained as were data on health and lifestyle factors. Alcohol consumption was assessed with the Alcohol Use Disorders Identification Test. Results In men, weekly alcohol consumption had a positive linear association with ventricular volume and gray matter and a negative linear association with white matter. In women, weekly alcohol consumption had a nonlinear relationship with cerebrospinal fluid and white matter. Alcohol consumption was not associated with white matter hyperintensities, corpus callosum size, hippocampal or amygdala volumes in analyses adjusting for confounding variables. Conclusion An association between alcohol consumption and brain atrophy is evident at the population level. In women, detrimental effects of alcohol on the brain appear to occur at lower levels of consumption. It remains possible that low levels of alcohol consumption have neuroprotective benefits but is clear that high levels of consumption are detrimental.
