Five-factor personality traits and subjective health among caregivers: the role of caregiver strain and self-efficacy

This study examined the association among caregivers' five-factor personality traits and subjective health with particular emphasis on the role of two theoretically implicated mediators: multi-domain self-efficacy and caregiver strain. The sample comprised 536 informal caregivers (mean age = 62.9 years, SD = 19.9, 72% female, 98% White) of community-dwelling older adults with multiple functional impairments. Both physical health and mental health were negatively associated with neuroticism and positively associated with extraversion and conscientiousness. Agreeableness and openness were associated with better subjective mental health and physical health, respectively. Multiple mediation analyses indicated that self-efficacy mediated all observed associations between personality and subjective health, whereas caregiver strain selectively mediated the associations of neuroticism and agreeableness with mental health.     

Personality traits and subjective health in the later years: The association between NEO-PI-R and SF-36 in advanced age is influenced by health status

This study examined the association between personality traits (as measured by the NEO-PI-R) and subjective ratings of mental and physical health (as measured by the SF-36) in two samples of older adults differing in health status (Baltimore Longitudinal Study of Aging, BLSA, n = 393, vs. Medicare Primary and Consumer-Directed Care Demonstration, Medicare PCC, n = 648). The association between personality traits and subjective mental health did not differ significantly across samples. The association between personality and subjective physical health, however, was significantly stronger in the healthy BLSA sample than in the medically challenged Medicare PCC sample. Differences in health conditions and recent hospitalizations partially accounted for this effect. Lifespan developmental considerations and implications for the use of subjective health ratings as outcome measures in clinical studies are discussed.     

Social exchanges and subjective well-being among older Chinese: does age make a difference?

The authors examined the effects of social support and negative interactions on life satisfaction and depressed affect among older Chinese, and age differences in these associations. The sample consisted of 2,943 Chinese elders who were 60-94 years of age. Structural equation modeling results suggest that both social support and negative interactions have significant contributions to life satisfaction and depressed affect. Social support has stronger effects than negative interactions on life satisfaction; their effects on depressed affect are comparable. Further, depressed affect of old-old (70+ years) Chinese reacts more strongly to both social support and negative interactions than the young-old (60-69 years).     

The Roles of Social Support and Self-Efficacy in Physical Health’s Impact on Depressive and Anxiety Symptoms in Older Adults

Physical illness may precipitate psychological distress among older adults. This study examines whether social support and self-efficacy moderate the associations between physical health and depression and anxiety. Predictions were tested in 222 individuals age 60 or older presenting for help with worry. Physical health was assessed through self-report (subjective) and physical diagnoses (objective). Objective physical health did not have a significant association with depression or anxiety. Worse subjective physical health was associated with increased somatic anxiety, but not with depression or worry. The relationship between subjective physical health and depressive symptoms was moderated by self-efficacy and social support. As predicted, when self-efficacy was low, physical health had its strongest negative association with depressive symptoms such that as physical health improved, depressive symptoms also improved. However, the moderation effect was not as expected for social support; at high levels of social support, worse physical health was associated with increased depressive affect.     

A descriptive epidemiology of lifetime trauma and the physical health status of older adults

Three issues are evaluated in this study. The 1st involves examining the relationship between exposure to trauma over the life course and physical health status in old age. The 2nd has to do with seeing whether the relationship between trauma and health varies across 3 cohorts of older adults: the young-old (ages 65-74), the old-old (ages 75-84), and the oldest old (age 85 and over). The 3rd issue involves seeing whether the age at which a trauma was encountered is related to health in late life. Data from a nationwide survey of older people (N=1,518) reveal that trauma is associated with worse health. Moreover, the young-old appear to be at greatest risk. Finally, data suggest that trauma arising between the ages of 18 and 30 years, as well as ages 31 to 64 years, has the strongest relationship with current health.     

Ongoing Cumulative Chronic Stressors as Predictors of Well-Being in the Second Half of Life

The main aim of the present study was to examine the relationship between ongoing cumulative chronic stressors (OCCS) and well-being during the second half of life. The sample comprised 7,268 participants who had completed the Health and Retirement Study 2006 psychosocial questionnaire and the full OCCS questionnaire. OCCS were evaluated as a predictor of Subjective Well-Being and Psychological Well-Being (PWB) using two measures: the number of events and the subjective evaluation attributed to the events by the participant. Additionally, the association between OCCS and well-being was evaluated in midlife (50–64), young-old (65–79), and old-old (80–104) participants. The results showed that the participant’s age as well as the number of OCCS perceived as “very upsetting” were strong predictors of well-being. The relationship between OCCS and PWB was weaker among old-old participants than among midlife and young-old participants. Although well-being is considered a stable trait-like personality dimension in the second half of life, the study’s findings suggest that as the number of OCCS was higher, and especially as the subjective evaluations attributed to an event are more upsetting, well-being was lower. Nevertheless, this lower level of well-being is partially moderated in the PWB measures by age. Old-old participants maintain a higher general positive sense of PWB than midlife and young-old participants in what was previously termed the “well-being paradox.” Implications of the results are discussed.     

Age-related binding deficits and the content of false memories

The authors examined effects of age-related binding deficits on feature information in false memories for imagined objects (e.g., lollipop) that were similar in shape to seen objects (e.g., magnifying glass). In Experiment 1, location memory for seen objects was lower in older than younger adults and lower still in old-old than young-old adults. Imagined objects, when falsely called seen, were less likely to be attributed to the location of similar seen objects (i.e., congruent attributions) by old-old than young-old adults. In Experiment 2, for younger adults, displaying seen objects for less time (1 s vs. 4 s) reduced both location memory for seen objects and congruent attributions for false memories. Thus, binding deficits may influence the specific content of false memories.     

Dynamic links between memory and functional limitations in old age: longitudinal evidence for age-based structural dynamics from the AHEAD study

This study examined competing substantive hypotheses about dynamic (i.e., time-ordered) links between memory and functional limitations in old age. We applied the Bivariate Dual Change Score Model to 13-year longitudinal data from the Asset and Health Dynamics Among the Oldest Old Study (AHEAD; N = 6,990; ages 70 - 95). Results revealed that better memory predicted shallower increases in functional limitations. Little evidence was found for the opposite direction that functional limitations predict ensuing changes in memory. Spline models indicated that dynamic associations between memory and functional limitations were substantively similar between participants aged 70-79 and those aged 80-95. Potential covariates (gender, education, health conditions, and depressive symptoms) did not account for these differential lead-lag associations. Applying a multivariate approach, our results suggest that late-life developments in two key components of successful aging are intrinsically interrelated. Our discussion focuses on possible mechanisms why cognitive functioning may serve as a source of age-related changes in health both among the young-old and the old-old.     

A Salutogenic Analysis of the Well-Being Paradox in Older Age

Following Antonovsky’s salutogenic perspective, we investigate to what extent the sense of coherence and psychological resources mediate the physical health-mental health relationship, assuming that these resilience factors mutually influence each other. In our questionnaire study, 387 older persons at the mean age of 73.8 years volunteered. We assessed physical health appraisals, sense of coherence components (comprehensibility, manageability, and meaningfulness), psychological resources (self-efficacy and self-esteem) and mental health (subjective well-being, depressive mood, and psychological health). We used structural equation modeling with latent variables and a bootstrapping method to test hypothesized mediation chains. We found (a) a significant direct effect of physical health on mental health, (b) two significant specific indirect effects of physical health on mental health, substantiating that the sense of coherence was a stronger mediator than psychological resources, and (c) two significant 3-path mediated effects. Physical health is profoundly associated with mental health. However, resilience factors such as the sense of coherence and psychological resources enable older people to maintain mental health when confronted with chronic physical health problems.     

The effects of daily co-occurrence of affect on older adults’ reactivity to health stressors

Objectives: The present study examined age differences among older adults in the daily co-occurrence of affect and its potential role in buffering the negative effects of health stressors.

Design: Participants were from the Veterans Affairs Normative Aging Study and included 249 young-old adults (age = 60–79 years, M = 71.6) and 64 old-old adults (age = 80–89, M = 82.9) who completed questionnaires assessing stressors, physical health symptoms, and positive and negative affect for eight consecutive days.

Results: An independent samples t-test showed young-old and old-old adults did not significantly differ in their mean levels of daily co-occurrence of affect. The between-person relationships among stressors, health and daily co-occurrence of affect revealed that neither stressors nor health were significantly related to daily co-occurrence of affect. However, results from a multilevel model revealed a three-way cross-level interaction (health stressor × age group × co-occurrence of affect) where old-old adults with higher levels of co-occurrence of affect were less emotionally reactive to health stressors than young-old adults.

Conclusion: These findings provide support for the assertion that co-occurrence of affect functions in an adaptive capacity and highlight the importance of examining domain-specific stressors.     

Cross-Sectional and Longitudinal Associations between Leisure Time Physical Activity,Mental Well-Being and Subjective Health in Middle Adulthood

Previous studies have shown that participation in leisure time physical activity is related to better mental well-being and subjective health. However, the associations between different types of leisure time physical activities and different dimensions of mental well-being have rarely been studied. In addition, longitudinal research, analyzing possible causal relations between these variables, is lacking. To investigate these research questions, data gathered at ages 42 and 50 (present N = 303) for the Finnish Jyväskylä Longitudinal Study of Personality and Social Development were used. Physical activity was assessed as frequency of participation at ages 42 and 50, and at age 50 also as frequency of participation in different types of physical activities. Mental well-being was captured by emotional, psychological and social well-being and subjective health by self-rated health and symptoms. Cross-sectionally, different types of physical activities were related to different dimensions of well-being. Walking had positive associations with psychological and social well-being, rambling in nature with emotional and social well-being, and endurance training with subjective health. Rambling in nature was also positively related to subjective health but only among men. Longitudinally, mental well-being predicted later participation in leisure-time physical activity, whereas no longitudinal associations between subjective health and physical activity were found. The results suggest that leisure time physical activities are related to current mental well-being and subjective health in midlife. Across time, good mental well-being seems to be a resource promoting engagement in physical activity.

     

Differential effects of age on prospective and retrospective memory tasks in young, young-old, and old-old adults

Remembering to do something in the future (termed prospective memory) is distinguished from remembering information from the past (retrospective memory). Because prospective memory requires strong self-initiation, Craik (1986) predicted that age decrements should be larger in prospective than retrospective memory tasks. The aim of the present study was to assess Craik's prediction by examining the onset of age decline in two retrospective and three prospective memory tasks in the samples of young (18-30 years), young-old (61-70 years), and old-old (71-80 years) participants recruited from the local community. Results showed that although the magnitude of age effects varied across the laboratory prospective memory tasks, they were smaller than age effects in a simple three-item free recall task. Moreover, while reliable age decrements in both retrospective memory tasks of recognition and free recall were already present in the young-old group, in laboratory tasks of prospective memory they were mostly present in the old-old group only. In addition, older participants were more likely to report a retrospective than prospective memory failure as their most recent memory lapse, while the opposite pattern was present in young participants. Taken together, these findings highlight the theoretical importance of distinguishing effects of ageing on prospective and retrospective memory, and support and extend the results of a recent meta-analysis by Henry, MacLeod, Phillips, and Crawford (2004).     

Depression and resilience mediate the relationship between traumatic life events and ill physical health: results from a population study

We set out to investigate the mediating roles of depression, resilience, smoking, and alcohol use, in the relationship between potentially traumatic life events and objective and subjective, physical and mental health in a single study. A face-to-face, population-based survey was conducted in Hong Kong (N = 1147). Information on health conditions and traumatic life events was obtained, and participants completed measures of subjective physical and mental health, depression, and resilience. Smoking and drinking were not significant mediators of the relationship between life events and both objective and subjective health. Depressive symptomatology was found to mediate the relationship between life threatening illness and subjective physical health, the relationship between abuse (physical and sexual) and subjective mental health, and the relationship between the death of a parent/partner and subjective mental health. Resilience was found to mediate the relationships between multiple traumatic life events and subjective physical and mental health. Our results indicate that psychological factors rather than biological are important mediators of the relationship between life events exposure and health. Our findings provide evidence that depressive symptomatology has a mediating role only in the case of specific potentially traumatic life events and that resilience is only a critical factor in the face of exposure to multiple traumatic events, rather than single events. Our results also indicate that behavioural factors, such as smoking and drinking, are not significant mediators of the relationship between life events and health.     

Identification of odors of edible and nonedible stimuli as affected by age and gender

This study investigated cued odor identification performance with a set of 64 natural common odors (half of edible and half of nonedible stimuli) in three groups of participants: one group of 30 young adults (mean age 25.3 years, range 18-30, SD 3.1) and two groups of older adults-20 young-old (mean age 64.4 years, range 60-69, SD 2.8) and 21 old-old (mean age 74.6 years, range 70-79, SD 2.5). The results showed that 49 of the 64 odors were correctly identified by over 70% of the participants in all groups. The odor identification performance of the young-old adults did not differ from that of the young adults. However, the oldest group showed a significant loss of performance in the task. Women in the young-old group performed better than men, whereas no gender differences were found in the other two age groups. The data obtained in this study will be useful for further perceptual and memory studies conducted in the olfactory modality with young as well as with older participants.     

Cognitive Mechanisms Underlying Decrements in Mental Synthesis in Older Adults

The extent and nature of age-related differences in mental synthesis was examined in light of Baddeley's working memory model and resource theories. Mental synthesis performance of 30 young, young-old, middle-old and old-old adults was examined using a dual-task experiment and individual differences approach. Age-related differences in mental synthesis were shown, with an unprecedented heightened decrement evident after the age of 85. The central executive was not a mechanism of this decline. Executive function, speed of information processing, and working memory capacity were mechanisms underlying this decline, and together accounted for 86% of the age-related variance in mental synthesis. Environmental support enhanced mental synthesis.     

Naturally occurring and experimentally induced tip-of-the-tongue experiences in three adult age groups.

Tip-of-the-tongue (TOT) experiences were examined in 30 young (ages 18-24 years), 30 young-old (ages 60-74), and 30 old-old (ages 80-92) adults. In Study 1, TOT experiences were experimentally induced with definitions of to-be-retrieved targets. If the target was not retrieved, orthographic or semantic cues were provided. Age-related increases in the occurrence of TOT experiences and in the time needed to resolve TOT experiences were found for young versus young-old and young-old versus old-old groups; all comparisons were significant except for young versus young-old TOT occurrence, which approached significance. In Study 2, the same participants recorded naturally occurring TOT experiences in structured diaries during a 4-week interval. Both the number of TOT experiences and the resolution time for TOT experiences increased with age. However, the percentage of TOT experiences resolved was equal across age groups; given enough time, even the oldest participants resolved virtually all TOT experiences.     

The contribution of personal resources to physical and mental health: looking into age and gender effects

In this study, a model that specified the effects of socioeconomic and psychological resources on physical and mental health was investigated. It was hypothesized that (a) both kinds of resources would affect physical and mental health more strongly in older than in younger adults, and that (b) socioeconomic resources would exert stronger effects in men, whereas psychological resources would exert stronger effects in women. Data were collected in an Israeli national sample. Structural modeling analyses indicated that the model fit the data. A comparison of 4 groups of participants (2 age groups--18-39 and 40-84--and both genders) showed that, for men, the respective effects of socioeconomic and psychological resources on physical and mental health were strong in the older, but not in the younger, group. For women, socioeconomic resources had nonsignificant effects, whereas psychological resources had strong effects on mental health in both age groups; psychological resources also had a moderate effect on physical health in the older group. The results suggest that the contribution of personal resources to health is regulated by the joint impact of age and gender, presumably involving shifting roles and vulnerabilities of men and women across the life span.     

老年人乐观、领悟社会支持与主观幸福感的关系—控制策略的中介作用

基于毕生控制理论，方便选取杭州市60~95岁的老年人320名，采用问卷法考察了老年人控制策略使用的现状和特点，并在控制了年龄、健康状况、日常活动数量后，探讨了老年人的乐观、领悟社会支持与主观幸福感的关系，以及控制策略的中介作用。结果发现：低龄的老年男性和女性更偏好选择初级和补偿初级策略，而高龄老年女性更偏好补偿初级策略；乐观和领悟社会支持不仅可以直接影响老年人的主观幸福感，还可以通过选择初级策略间接影响主观幸福感。初级控制在老年人中依然具有首要性地位，老年人的资源越丰富，越有可能采用积极的控制策略（选择初级），进而提高主观幸福感，实现成功老龄化。     

Effects of Age and Intentionality on Content Memory and Temporal Memory for Performed Activities

Seventy-two young (18–28), 72 young-old (ages 57–70), and 72 old-old (71–93) adults completed 10 different laboratory activities. Intention to learn the content of the activities and their temporal order was varied within each age group by manipulating type of encoding instruction given to the participant (i.e., either incidental, intentional for content, or intentional for both content and temporal order). Participants' recall, recognition, and temporal memory proficiency for the activities was then evaluated. The results revealed that both content memory and temporal order memory for the performed activities were enhanced by intentional encoding strategies. Young adults performed better on the temporal ordering task than young-old adults, with temporal memory proficiency continuing to show further decline in the old-old group. In contrast, content recall and recognition abilities were impaired only in the old-old group. The results suggest that strategic encoding processes can enhance memory for performed activities, and that age-related deficits in temporal order efficiency may occur earlier than those involved in memory for the content of performed activities.     

Associations between social capital and health status in an Australian population

This study investigated the association between social capital and health related quality of life in a sample of Australian adults. Information was collected from a sample of adults in Queensland, Australia relating to health status, health related quality of life and related social determinants of health by computer-assisted-telephone-interview survey. Significant associations were observed between social capital and physical health when adjusting for selected demographic measures. No significant association was observed between social capital and mental health. The research produced equivocal results regarding the associations between social capital and the selected measures of health-related quality of life. Evidence is presented in support of the association between social capital and physical health status, whereas no associations were observed between mental health status and social capital. The role and relationship between health and social capital remains elusive. More work is required to clearly support social capital's role in physical and mental health and well-being.
