Personality in advanced old age: continuity or change?

Exploring challenges in later-life relationships: a qualitative study of the queries posted on counselling websites

Introduction

Divorce rates among individuals aged 50 and above are on the rise. Given the greater life expectancy compared to previous generations, this is an issue that is affecting an increasing number of people. Therefore, it warrants an inquiry into the challenges these individuals encounter in their intimate relationships.

Methods

This study analyzed 225 relationship-related queries posted on Czech counselling websites to identify the strains and stressor patterns that older adults face in their relationships. The queries were limited to those that concerned themes and problems related to partnerships, were posted by one of the partners aged 60 or over, and were analyzed using inductive thematic analysis.

Results

Four main relationship issues were identified: infidelity and jealousy; relationship estrangement and cooling; undesirable changes in personality; and illness and somatic issues. Additionally, three recurring themes were identified that made the problems more demanding and that were specific to older age: lack of norms for relationships in that age group, absence of resources to tackle the issues, and personal calculation for Time Spent and Time Remaining.

Discussion

The research found that the types of problems encountered by older adults were similar to those experienced by younger individuals. However, the way these problems were perceived and processed was influenced by specific aspects of aging, such as societal expectations, available coping resources, and the perception of time. The findings also highlighted the challenges faced by older adults in terms of relationship norms, sexual functioning, and personality changes.

Relationships Among Personality, Daily Speaking Voice Use, and Phonotrauma in Adult Female Singers

PURPOSE

This study sought to determine whether personality traits related to extraversion and impulsivity are more strongly associated with singers with nodules compared to vocally healthy singers and to understand the relationship between personality and the types of daily speaking voice use.

METHOD

Weeklong ambulatory voice recordings and personality inventories were obtained for 47 female singers with nodules and 47 vocally healthy female singers. Paired t tests investigated trait differences between groups. Relationships between traits and weeklong speaking voice measures (vocal dose, sound pressure level [SPL], neck surface acceleration magnitude [NSAM], fundamental frequency, cepstral peak prominence [CPP], and the ratio of the first two harmonic magnitudes [H 1 -H 2]) were examined using pairwise Pearson r coefficients. Multiple regressions were performed to estimate voice parameters that correlated with two or more traits.

RESULTS

Singers with nodules scored higher on the Social Potency scale (reflecting a tendency toward social dominance) and lower on the Control scale (reflecting impulsivity) compared to the vocally healthy singers. In vocally healthy singers, vocal dose measures were positively correlated with a combination of Wellbeing (i.e., happiness) and Social Potency, mean SPL was positively correlated with Wellbeing, SPL variability was positively correlated with Social Potency and negatively with Harm Avoidance, and CPP mean was positively correlated with Wellbeing. Singers with nodules had a negative correlation between NSAM skewness and Social Potency. Both groups had negative correlations between H 1 -H 2 mean and Social Potency and Social Closeness.

CONCLUSIONS

Singers with nodules are more socially dominant and impulsive than vocally healthy singers. Personality traits are related to daily speaking voice use, particularly in vocally healthy singers. Individuals with higher levels of traits related to happiness and social dominance and lower Harm Avoidance tended to speak more, with higher laryngeal forces, with more SPL variability, and with more pressed glottal closure, which could increase risk of phonotrauma.

Correlations between implant success rate and personality types in the older people: A preliminary case control study

Background/ purpose

Older patients inevitably have a higher need for implant treatment, it is unknown how mental changes or psychological aspects affect the outcome of implant treatment. This study evaluated the success rate of implants and the influence of personality traits in the older people. The goal was to provide evidence for predictable implant treatment while taking into account the unique psychological changes of elders.

Materials and methods

Participants were patients who were able to independently visit our hospital between March 2004 and May 2021. Inclusion criteria were patients aged 65 years or older at the time of implant placement with regular follow-up for at least 1 year. The implant success rate was calculated by counting peri-implantitis and implant loss as failures. Multivariate analysis was used to examine the effect of patient personality characteristics on the success rate.

Results

Fifty-six implants were included in 23 patients (12 men, 11 women), with a mean age of 68.5 years (65–76) and mean maintenance duration of 9 years and 2 months. The cumulative survival rate was 87% at the patient level (94.6% at the implant level). Statistically significant differences were found for adaptive traits (odds ratio [OR] = 0.04) and non-adaptive traits (OR = 6.38); however, no significant differences were found for the other independent variables.

Conclusion

The overall implant success rate was 69.6% at the patient level (82.1% at the implant level). The personality traits in older people had a significant effect on the implant failure rate.

Aging perceptions and self-efficacy mediate the association between personality traits and depressive symptoms in older adults

OBJECTIVE

Personality traits have been shown to be predictors of depressive symptoms in late life. Thus, we examined whether other more modifiable sources of individual differences such as self-efficacy and self-perceptions of aging would mediate the association between personality traits and depressive symptoms in older adults.

METHOD

Data were obtained from 3,507 older adult participants who took part in the 2012 Health and Retirement Study. The "Big Five" personality traits, self-efficacy, aging perceptions, and depressive symptoms were assessed. Mediation analyses tested the hypothesis that self-efficacy and aging perceptions would mediate the relationship between personality traits and depressive symptoms.

RESULTS

All five personality traits were significant predictors of depressive symptoms. Neuroticism was positively associated with depressive symptoms and had the greatest effect compared with the other personality traits. There was a significant indirect effect of neuroticism, extraversion, and conscientiousness on depressive symptoms (including both mediators). The mediating effect of aging perceptions on the relationship between neuroticism and depressive symptoms was the strongest compared with self-efficacy, accounting for approximately 80% of the total indirect effect.

CONCLUSION

Our results provide support for interventions aimed at improving self-perceptions related to efficacy and aging in order to reduce depressive symptoms in older adults. Copyright © 2016 John Wiley & Sons, Ltd.

Development of Adaptive Coping From Mid to Late Life: A 70-Year Longitudinal Study of Defense Maturity and Its Psychosocial Correlates

The present study examines changes in defense maturity from mid to late life using data from an over 70-year longitudinal study. A sample of 72 men was followed beginning in late adolescence. Participants' childhoods were coded for emotional warmth. Defense mechanisms were coded by independent raters using the Q-Sort of Defenses (, Ego mechanisms of defense: A guide for clinicians and researchers 217-233) based on interview data gathered at approximately ages 52 and 75. We examined psychosocial correlates of defenses at midlife, late life, and changes in defense from mid to late life. Overall, defenses grew more adaptive from midlife to late life. However, results differed on the basis of the emotional warmth experienced in the participants' childhoods. In midlife, men who experienced warm childhoods used more adaptive (mature) defenses; yet by late life, this difference in defensive maturity had disappeared. Men who experienced less childhood warmth were more likely to show an increase in adaptive defenses during the period from mid to late life.

Relations between personality changes and cerebrospinal fluid biomarkers of Alzheimer's disease pathology

Specific changes in personality profiles may represent early non-cognitive symptoms of Alzheimer's disease (AD). Evaluating the subject's personality changes may add significant clinical information, as well as help to better understand the interaction between personality change, cognitive decline, and cerebral pathology. With this study we aimed to describe the relationship between personality changes and cerebrospinal fluid (CSF) markers of AD pathology at early clinical stages of the disease. One hundred and ten subjects, of whom 66 cognitively impaired patients (57 with mild cognitive impairment (MCI), and 9 with mild dementia) and 44 healthy controls, had neuropsychological examination as well as lumbar puncture to determine concentrations of CSF biomarkers of AD pathology (amyloid beta_1-42 (Aβ_1-42), phosphorylated tau (ptau-181), and total-tau (tau)). The Revised NEO Personality Inventory (NEO-PI-R) was administered twice, once to evaluate subjects' current personality and once to assess personality traits retrospectively 5 years before evaluation. Subjects with an AD CSF biomarker profile showed significant increase in neuroticism and decrease in conscientiousness over time as compared to non-AD CSF biomarker group. In regression analysis controlling for global cognition as measured by the MMSE score, increasing neuroticism and decreasing extraversion, openness to experience and conscientiousness were associated with lower Aβ_1-42 concentrations but not with tau and ptau-181 concentrations. Our findings suggest that early and specific changes in personality are associated with cerebral AD pathology. Concentrations of CSF biomarkers, additionally to severity of the cognitive impairment, significantly contribute in predicting specific personality changes.

Demographics, phenotypic health characteristics and genetic analysis of centenarians in China

After a brief introduction to the background, significance and unique features of the centenarian population in China, we describe the Chinese Longitudinal Healthy Longevity Study (CLHLS), which is the world's largest study of centenarians, nonagenarians, octogenarians, and compatible young-old aged 65-79. Based on the CLHLS data and other relevant studies, we summarize demographic and socioeconomic characteristics as well as self-reported and objectively-tested health indicators of centenarians in China, with an emphasis on gender differences and rural/urban disparities. We then compare five-year-age-specific trajectories of physical and cognitive functions, self-reported health, and life satisfactions from ages 65-69 to 100+, concluding that good psychological resilience and optimism are keys to the exceptional longevity enjoyed by centenarians. We discuss recent findings of novel loci and pathways that are significantly associated with longevity based on the genome-wide association study (GWAS) of the CLHLS centenarian sample, which is 2.7 times as large as prior GWAS of longevity. We also highlight colleagues' and our own studies on longevity candidate genes and gene-environment interaction analyses. Finally, we discuss limitations inherent in our studies of centenarians in China and further research perspectives.

Co-Development of Personality and Friendships Across the Lifespan

Abstract. This article examines changes in the co-development of personality characteristics and friendships across the lifespan. We address how personality traits shape friendship development (i.e., selection effects) and how friendships shape personality traits (i.e., socialization effects). By integrating separate empirical studies, we look at how selection and socialization effects change across the lifespan. A review of longitudinal research supports our hypothesis that selection effects on friendships intensify during adolescence, peak in young adulthood, and diminish throughout middle and late adulthood. Socialization effects through friendships seem to be moderately sized during adolescence, then small to negligible from young adulthood onwards. For future directions, we discuss effects of the transactional development of friendships and personality regarding associated dispositions within individuals, associated individuals within friendship dyads, and individuals associated within wider social networks.

Gender Differentials of the Oldest Old in China

Based on unique data from a sample of nearly 9,000 people ages 80 to 105 interviewed in 22 provinces in 1998, we found that gender differentials in educational attainment among the Chinese oldest old are enormous: Many more women are illiterate. Oldest old women are more likely to be widowed and economically dependent, much less likely to have pensions, and thus more likely to live with their children and rely on children for financial support and care. The female oldest old in China are also seriously disadvantaged in activities of daily living, physical performance, cognitive function, and self-reported health, as compared with their male counterparts; these gender differences are more marked with advancing age. The large gender differentials among the Chinese oldest old need serious attention from society and government, and any old-age insurance and service programs to be developed or reformed must benefit older women and men equally.

Age and Sex Differences in Temperament and Character Dimensions in a French Nonclinical Population

Abstract. The authors examined age and sex trends on the seven dimensions and 25 facets assessed by the Temperament and Character Inventory (TCI) collected between 2006 and 2014. This cross-sectional study sought to better understand personality differences according to age and sex cohorts in a French nonclinical community sample (1,181 participants). Our results show significant differences in age groups in Novelty Seeking, Reward Dependence, Harm Avoidance, and Self-Transcendence. Women scored higher than men in Harm Avoidance, Reward Dependence, and Cooperativeness. Men between 18 and 29 years old reported higher Novelty Seeking whereas older women had higher Harm Avoidance. Among all the dimensions of the TCI, only Self-Directedness presents a consistent Gender × Age interaction. Our study confirmed that there were personality-specific features in men and women. In addition, there were personality changes with age in both temperament and character dimensions. Our research highlighted the need to take into account both age and gender of subjects in the future analyses and interpretations of findings from the temperament and character inventories.

Coupling of Temperament with Mental Illness in Four Age Groups

Studies of temperament profiles in patients with mental disorders mostly focus on emotionality-related traits, although mental illness symptoms include emotional and nonemotional aspects of behavioral regulation. This study investigates relationships between 12 temperament traits (9 nonemotionality and 3 emotionality related) measured by the Structure of Temperament Questionnaire and four groups of clinical symptoms (depression, anxiety, antisociality, and dominance-mania) measured by the Personality Assessment Inventory. The study further examines age differences in relationships among clinical symptoms and temperament traits. Intake records of 335 outpatients and clients divided into four age groups (18–25, 26–45, 46–65, and 66–85) showed no significant age differences on depression scales; however, the youngest group had significantly higher scores on Anxiety, Antisocial Behavior, Dominance, and Thought Disorders scales. Correlations between Personality Assessment Inventory and Structure of Temperament Questionnaire scales were consistent with Diagnostic and Statistical Manual of Mental Disorders, 4th Edition, descriptors showing strong concurrent validity. Several age differences on temperament scales are also reported. Results show the benefits of differentiation between physical, social-verbal, and mental aspects of activities, as well as differentiation between dynamical, orientational, and energetic aspects in studying mental illness and temperament.

Developmental Tasks as a Framework to Study Personality Development in Adulthood and Old Age

Research consistently shows that personality development is a lifelong phenomenon, with mean–level and rank–order changes occurring in all life phases. What happens during specific life phases that can explain these developmental patterns? In the present paper, we review literature linking personality development in different phases of adulthood to developmental tasks associated with these phases. Building on previous work, we describe several categories of developmental tasks that are present in all phases of adulthood. However, the specific tasks within these categories change across adulthood from establishing new social roles in early adulthood to maintaining them in middle adulthood and preventing losses in old age. This trajectory is reflected in mean–level changes in personality, which indicates development towards greater maturity (increases in social dominance, conscientiousness, and emotional stability) in early and middle adulthood, but less so at the end of life. Importantly, developmental tasks are not only associated with mean–level changes, but the way in which people deal with these tasks is also related to rank–order changes in personality. We provide an outlook for future research on how the influence of historical time on the normativeness of developmental tasks might be reflected in personality development.

Reciprocal Associations between Parenting Challenges and Parents’ Personality Development in Young and Middle Adulthood

Having children affects many aspects of people's lives. However, it remains unclear to what degree the challenges that come along with having children are associated with parents’ personality development. We addressed this question in two studies by investigating the relationship between parenting challenges and personality development in mothers of newborns (Study 1, N = 556) and the reciprocal associations between (mastering) parenting challenges and personality development in parents of adolescents (Study 2, N = 548 mothers and 460 fathers). In Study 1, we found the stress of having a newborn baby to be associated with declines in maternal Agreeableness, Conscientiousness, and Emotional Stability. Parenting challenges were also related to personality development in parents of adolescent children in Study 2, with parent–child conflict being reciprocally associated with decreases in Conscientiousness and Emotional Stability. Mastering parenting challenges in the form of high parenting self–efficacy, on the other hand, was found to be associated with increases in Agreeableness, Conscientiousness, and Emotional Stability, and vice versa. In sum, our results suggest that mastering the challenges associated with the social role of parenthood is one of the mechanisms underlying personality development in young and middle adulthood.

A 37-year prospective study of neuroticism and extraversion in women followed from mid-life to late life

OBJECTIVE

Personality traits are presumed to endure over time, but the literature regarding older age is sparse. Furthermore, interpretation may be hampered by the presence of dementia-related personality changes. The aim was to study stability in neuroticism and extraversion in a population sample of women who were followed from mid-life to late life.

METHOD

A population-based sample of women born in 1918, 1922 or 1930 was examined with the Eysenck Personality Inventory (EPI) in 1968-1969. EPI was assessed after 37 years in 2005-2006 (n = 153). Data from an interim examination after 24 years were analysed for the subsample born in 1918 and 1922 (n = 75). Women who developed dementia at follow-up examinations were excluded from the analyses.

RESULTS

Mean levels of neuroticism and extraversion were stable at both follow-ups. Rank-order and linear correlations between baseline and 37-year follow-up were moderate ranging between 0.49 and 0.69. Individual changes were observed, and only 25% of the variance in personality traits in 2005-2006 could be explained by traits in 1968-1969.

CONCLUSION

Personality is stable at the population level, but there is significant individual variability. These changes could not be attributed to dementia. Research is needed to examine determinants of these changes, as well as their clinical implications.

Aggravating conditions: cynical hostility and neighborhood ambient stressors

This study is the first to investigate neighborhood clustering of a personality trait--cynical hostility (a sense of mistrust of others amplified by suspicious antagonism.) Cynical hostility increases physiological reactivity by influencing appraisal and coping when stressful events occur and that has been well established as a predictor of cardiovascular disease, inflammation, and all-cause mortality. The analysis examines the associations of a variety of neighborhood physical and social conditions (especially ambient stressors) with individual cynical hostility, controlling for individual sociodemographics. Data are from the Chicago Community Adult Health Survey, a clustered population-based study of 3105 adults. Variation by neighborhood in cynical hostility is larger than variation of other selected health outcomes, which are commonly studied using ecological methods or for other personality measures. Controlling for neighborhood context reduces the black/white cynical hostility disparity by one-third. A measure of neighborhood ambient stressors (notably noise) significantly predicts cynical hostility, even after individual characteristics are controlled, and the effect size is larger than for other contextual predictors. Health-related psychosocial and personality traits may both cluster in and be influenced by contemporaneous neighborhoods rather than mere exogenous results of genes or early life conditions. Health-relevant psychosocial characteristics may also mediate effects of neighborhood deleterious physical conditions, thereby influencing downstream health outcomes and social disparities therein. Because residential location and neighborhood physical conditions are both modifiable, research on how ambient stressors influence health psychology may be particularly fruitful for health policy and practice.

Personality changes in Alzheimer's disease: a systematic review

OBJECTIVE

People with Alzheimer's disease (AD) commonly exhibit changes in personality that sometimes precede the other early clinical manifestations of the condition, such as cognitive impairment and mood changes. Although these personality changes reflect the impact of progressive brain damage, there are several possible patterns of personality change with dementia. Early identification of personality change might assist with the timely diagnosis of AD. The objective of this study was to review studies of personality change in AD.

METHODS

Systematic searches of the PubMed, Ovid Medline, EBSCOhost, PsychINFO and CINAHL databases were undertaken from inception to November 2009. Published studies of informant-rated personality traits in AD patients were identified. Studies that mapped changes in traits from the five-factor model of personality which includes factors for Neuroticism, Extraversion, Openness, Agreeableness and Conscientiousness, were selected for analysis. The change in each of these five traits was calculated as the mean difference in score before and after the diagnosis of AD.

RESULTS

There was a mean increase in Neuroticism of 10-20 T scores (equivalent to 1-2 SD), a decrease of the same magnitude in Extraversion, consistently reduced Openness and Agreeableness, and a marked decrease in Conscientiousness of about 20-30 T scores (equivalent to 2-3 SD). These changes were systematic and consistent. Particularly striking was the similarity of both the magnitude and direction of change in all studies reviewed.

CONCLUSIONS

Conscientiousness and Neuroticism are the personality traits that exhibit the most change in dementia. These traits might be useful early markers of dementia.

Psychological Models of Aging

The field of psychogerontology is data rich, but theory poor. It will be argued that a constructivist view of science in terms of models or metaphors encourages the development of theories in the field of aging. Historically, there are three psychological models: Age, aging and the aged. The psychology of the aged is concerned with the thematic study of the problematic and non-problematic elderly. The psychology of age focuses on age differences and compares groups of people of different ages. The psychology of aging studies some typicalness of change of average functioning over time. Recent psychological models of aging emphasize degree of variability, rather than average functioning. Primary, secondary and tertiary aging patterns are presented in terms of a differential psychology of aging. A theoretical explanation of the differential aging process will be given in terms of gerodynamics, which lays the foundation of the new branching model of aging.

A unifying perspective on personality pathology across the life span: developmental considerations for the fifth edition of the Diagnostic and Statistical Manual of Mental Disorders

Proposed changes in the fifth edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-V) include replacing current personality disorder (PD) categories on Axis II with a taxonomy of dimensional maladaptive personality traits. Most of the work on dimensional models of personality pathology, and on personality disorders per se, has been conducted on young and middle-aged adult populations. Numerous questions remain regarding the applicability and limitations of applying various PD models to early and later life. In the present paper, we provide an overview of such dimensional models and review current proposals for conceptualizing PDs in DSM-V. Next, we extensively review existing evidence on the development, measurement, and manifestation of personality pathology in early and later life focusing on those issues deemed most relevant for informing DSM-V. Finally, we present overall conclusions regarding the need to incorporate developmental issues in conceptualizing PDs in DSM-V and highlight the advantages of a dimensional model in unifying PD perspectives across the life span.

Impacto na qualidade de vida e no estado depressivo de idosas participantes de uma universidade da terceira idade

O objetivo deste estudo foi examinar a associação entre o tempo de participação na Universidade para a Terceira Idade da Universidade Federal do Rio Grande do Sul e as dimensões de personalidade, a qualidade de vida e a depressão em idosas. O método amostral utilizado foi o de conveniência. Cento e três idosas que participavam do grupo da Universidade da Terceira Idade foram avaliadas e responderam a instrumentos sobre condições sociodemográficas, aspectos de personalidade, qualidade de vida e depressão. Os resultados mostraram uma associação entre tempo de participação superior a um ano na Universidade da Terceira Idade e menor intensidade de depressão, bem como melhor percepção de qualidade de vida nos domínios físico, psicológico e social. Os resultados sugerem que o tempo de participação superior a um ano na Universidade da Terceira Idade atua como um possível fator protetor contra a depressão em idosos e auxilia na percepção de uma melhor qualidade de vida nos domínios físico, psicológico e social.

Differential Psychological Ageing: Profiles of the Old and Very Old

Theoretical positions which argue for age-related and individual variation in profiles of psychological functioning and patterns of predictive relationships are reviewed in the context of the three domains investigated by the Psychology Unit of the Berlin Aging Study (BASE): intelligence and cognition, self and personality, and social relationships. To illustrate the potential of BASE, we report initial data for a small set of variables from these three psychological domains for the first wave of study participants (N = 360, age range 70 to 103 years). Our analyses of these data were targeted toward three key questions about differential psychological ageing: namely, the extent of age/cohort-related differences and individual variation within each domain, possible age differences in the structural relationships between the three domains, and subgroup variations in cross-domain profiles of functioning. Within domains, individual differences in general were very large. Chronological age accounted for a sizeable proportion of the variance only in the domain of cognitive performance. The structural relationships between the domains of psychological functioning were similar for the old and very old age groups and reflected much domain independence. Examination of subgroup variations in cross-domain profiles of functioning revealed ten subgroups. All subgroups showed an uneven, that is, age-selective group membership: five subgroups included more of the very old, two more of the old, and three were age-specific. Preliminary explorations of these subgroups suggested substantial links to selected health-related variables, supporting proposals for multi-disciplinary research into differential ageing.

Self-Esteem and its Sources: Stability and Change in Later Life

Stability and change in self-esteem and its reported sources were investigated in a sample of older people re-interviewed 10 and 13 years after initial study. Most indicated a continuing high to medium-high level of self-esteem, and apart from an increase in mention of interest activities their pattern of illustrations also remained consistent. Variables in the initial study which predicted a maintained high level of self-esteem included number of hobbies, number of types of outings, self perceived activity level, and mention of people other than family members as sources of self-esteem. The usefulness of collecting data on expressed sources is exemplified in two case histories. Consideration is given to the implications of these findings for conceptualising identity processes in later life.

Personality and health in Japanese older adults

OBJECTIVE

Change versus stability of personality in late adulthood is an intriguing yet understudied issue. This cross-sectional study examined age and gender differences in Cloninger's biosocial model of personality, as well as their relation to health in a Japanese community sample whose age exceeds 50 years.

METHOD

Participants (N=330) completed the Temperament and Character Inventory and the General Health Questionnaire. MANOVA and hierarchical regression analyses were conducted.

RESULTS

Age-related decreases in Reward Dependence, Self-Directedness, Cooperativeness, and an increase in Self-Transcendence were found. Health was significantly predicted by Harm Avoidance and Self-Directedness.

CONCLUSION

Personality change in late adulthood tends to occur in environmentally-based character, in a pattern of gradual social detachment and internal spiritual growth. Personality is a stronger predictor of health than demographic variables.

Personality and Defense Mechanisms in Late Adulthood

Objective: Current understanding of the use of psychological defense mechanisms (DMs) in older adults is limited. This study set out to examine individual differences in DMs and Cloninger's biosocial model of personality in two age groups (50—64, 65—93), as well as their influence on health. Methods: A Japanese community sample ( N = 330) completed the Temperament and Character Inventory (TCI-125), the Defense Style Questionnaire (DSQ-40), and the General Health Questionnaire (GHQ-28). Results: Across age groups, psychological well-being was related to lower levels of harm avoidance and higher levels of self-directedness. In addition, older age was related to decreases in reward dependence, cooperativeness, and increases in self-transcendence, DMs of isolation, denial, and splitting. Discussion: An Age × Gender interaction revealed that men and women varied in their pattern of age differences for some specific DMs. Results further suggest that image-distortion defense may function to compensate resource loss.

Patterns of mean-level change in personality traits across the life course: a meta-analysis of longitudinal studies

The present study used meta-analytic techniques (number of samples = 92) to determine the patterns of mean-level change in personality traits across the life course. Results showed that people increase in measures of social dominance (a facet of extraversion), conscientiousness, and emotional stability, especially in young adulthood (age 20 to 40). In contrast, people increase on measures of social vitality (a 2nd facet of extraversion) and openness in adolescence but then decrease in both of these domains in old age. Agreeableness changed only in old age. Of the 6 trait categories, 4 demonstrated significant change in middle and old age. Gender and attrition had minimal effects on change, whereas longer studies and studies based on younger cohorts showed greater change.

Aging, Emotion, and Evolution

Ample empirical evidence shows that basic cognitive processes integral to learning and memory suffer with age. Explanations for age-related loss typically cite the absence of evolutionary selection pressures during the postreproductive years, which consequently failed to optimize functioning during old age. In this paper, we suggest that evolutionary pressures did operate at older ages and that an evolutionary account is entirely consistent with the pattern of findings currently available in the psychological literature on aging. Cognitive loss is limited primarily to new learning, yet integrated world knowledge increases with age. In addition, socioemotional regulation improves with age, which is associated with increased investment in emotionally meaningful others (most notably kin). In this chapter, we argue that this profile of late-life characteristics contributes to the reproductive success of kin. We consider how the uniquely human ability to monitor place in the life cycle and the consequent motivational shifts that occur when boundaries in time are perceived contribute to the adaptive value of long life. Finally, we suggest that joint consideration of evolutionary theory and life-span psychology can lead to fruitful advances in the understanding of human aging.

Adverse factors and the mental health of older people: implications for social policy and professional practice

Defining 'older people' as a homogenous group is problematic; it can lead to stereotypical and stigmatizing perceptions of what old age is, attracting consequent negative attitudes to later life. Nevertheless, evidence suggests that some in the older age bracket are subject to particular stressors and physical changes that can adversely affect their mental health. This paper will consider challenges to mental health in older age groups and particularly the phenomenon of dementia. The role and influence of diagnosis, social policy and professional practice will also be addressed and suggestions will be made as to how people could improve their responses to either the predisposition to or the actual occurrence of mental distress in later life. In addition, it is argued that person-centredness is important as the caring/cultural medium through which provisions and policies are mediated: that obtaining appropriate balances between corporate and individual contributions and interventions must constitute the context wherein future developments lie.

Body image across the adult life span: stability and change

By far, the majority of studies investigating body image in adults have drawn samples from college populations within a very narrow age range. The purpose of the present paper is to review empirical research on the body image of adults older than the typical college student. There are marked changes in appearance across the adult life span, especially for women, which lead to the expectation of concomitant changes in body image. In fact, the review found that body dissatisfaction was remarkably stable across the adult life span for women, at least until they are quite elderly. In contrast, the importance of body shape, weight and appearance decreased as women aged, underscoring an important distinction between evaluation and importance of the body. However, there are many large gaps and limitations in the current literature that will need to be addressed before a more complete understanding of the development of body image across the adult life span is achieved.

The oldest-old: how do they differ from the old-old?

This article reviews findings from the Berkeley Older Generation Study, a long-term longitudinal study of aging. The findings show many important differences between the oldest-old age group and other, younger-old individuals. Marked variation is demonstrated in the verbal scale of intelligence. More than half of oldest-old individuals did not decline, and some actually increased in verbal IQ. Four personality traits (i.e., agreeableness, satisfaction, intellect, extroversion) are stable. The fifth trait, energetic, may reflect responses to external circumstances, including physical health. As for social relationships, most individuals--including the oldest-old--still retain ties with important family members and friends. Individual differences are great, stressing the danger of accepting stereotypes about old individuals.

The rank-order consistency of personality traits from childhood to old age: a quantitative review of longitudinal studies

The present study used meta-analytic techniques to test whether trait consistency maximizes and stabilizes at a specific period in the life course. From 152 longitudinal studies, 3,217 test-retest correlation coefficients were compiled. Meta-analytic estimates of mean population test-retest correlation coefficients showed that trait consistency increased from .31 in childhood to .54 during the college years, to .64 at age 30, and then reached a plateau around .74 between ages 50 and 70 when time interval was held constant at 6.7 years. Analysis of moderators of consistency showed that the longitudinal time interval had a negative relation to trait consistency and that temperament dimensions were less consistent than adult personality traits.

Toward holistic theory-based intervention for dementia behavior

Four million Americans suffer from some form of dementia. Over 50% of these individuals exhibit behaviors that are perceived as "disturbing" by family and caregivers. The Need-driven Dementia-compromised Behavior Model was developed by a group of nurse researchers to study and understand these behaviors. The model changes the view of dementia behaviors as "disturbing" to that of behavior as signifying potentially understandable needs. This article reviews the model and demonstrates how interventions derived from the model can be used to respond to dementia behaviors in a holistic fashion.

Personality disorder and the Temperament and Character Inventory in the elderly

OBJECTIVE

The aim of this study was to determine the prevalence of personality disorders in a group of elderly patients without an organic mental disorder and to examine the relationship between the Temperament and Character Inventory (TCI) and personality disorder symptoms in psychogeriatric clinical practice.

METHOD

A total of 91 subjects completed the Structured Clinical Interview for DSM-III-R personality questionnaire and the 125-item TCI.

RESULTS

Of the 91 subjects, 34 individuals (31%) had at least one DSM-III-R personality disorder diagnosis, with avoidant, dependent and paranoid personality disorder being the most common. The trends and correlations between the temperament and character dimensions and the correlations between individual personality disorder symptoms and the dimensions were similar to those in the original model. The most significant findings were the strong negative correlations of the character scores of self-directedness and co-operativeness with the total number of personality disorder symptoms, and the fact that the self-directedness scores predicted the number of personality disorder diagnoses.

CONCLUSION

The reported prevalence rate is comparable to studies of both younger and older patient populations using similar methodology. The TCI provides a useful framework for further research on personality disorders in the elderly.

Continuity in the lives of elder catholic women religious

Data from life review interviews with thirty-nine elder Catholic women religious (68-98) show these women's lives do not conform to a sequential pattern of late life developmental stages. Their lives can best be understood in terms of continuous themes throughout individual lives. The majority of the women reach ego integrity in young old age and continue to reestablish this by adhering to themes in their life stories. Themes serve as a framework of the self. The main themes of the participants are: faith, family, education, friends, community, caring for others, and prayer. Communal aspects of religious life support the women in their continuous development of identity. Generativity is evidenced in their lives as an ongoing component of self-identity. These data show the continuous process of establishing ego integrity throughout late life. The life review data can best be explained using the continuity theory of identity development.

"Looking back, what period of your life brought you the most satisfaction"

Common myths hold that old persons are fixated on childhood memories, that they believe that youth is the best part of life, and that old age contains few satisfactions. Berkeley Older Generation Study members, when asked on two occasions during old age (M ages = 69.8 and 82.7) to name the periods of their lives that brought them the most and the least satisfaction, dispelled these myths. The thirties and forties were popular choices for periods of great satisfaction, but childhood and adolescence were quite unpopular for these old persons. "Right now" was named more often than any other life period as most satisfactory. Men and women did not differ in life periods nominated, but they did differ in the reasons given for their choices. Each period provided its own pattern of satisfactions and disappointments, and strong individual differences were apparent.

Aging and depression: vulnerability and stress across adulthood

This paper reviews research on the relationship between age and depression in adulthood, with a focus on depression in late life. Age differences in prevalence rates of major depression and depressive symptomatology raise questions about presentation and measurement of depression across adulthood, and suggest a changing salience of risk factors for depression from young adulthood through old age as well as to cohort differences in risk for depression. Applying a developmental perspective on biological change, psychological adaptation, and stress processes throughout adulthood shows that risk for depression onset in young adults is typified more through psychological vulnerability and stress, as well as genetic factors, while risk for depression in older adults typified more through comorbid medical and neurological disorder. Implications for research and clinical practice are discussed. This review of the relationship of age to depression shows that the study of psychopathology and adult development can inform each other.

Life-span perspective of personality in dementia

PURPOSE

To propose an alternative view of personality change in dementia by presenting existing evidence for the continuity of personality.

SIGNIFICANCE

As the population continues to age, dementing illnesses will account for a greater proportion of morbidity and mortality; the care of these people will have a significant effect on the health care system.

ORGANIZING FRAMEWORK

Life-span perspective of personality continuity. SCOPE METHOD: Review of current literature on personality in dementia using Medline, 1980-1994; CINAHL, 1990-1994; and Psych Lit., 1980-1994.

FINDINGS

Although there are systematic shifts in personality with dementia, individuals tend to maintain their unique pattern of premorbid personality traits.

CONCLUSIONS

The personalities of dementia patients seem to reflect adaptive patterns that served them in the past.

IMPLICATIONS

Use of a life-span perspective can enhance individualized care for demented patients and advance theory development.

Personality change in Parkinson's disease patients: chronic disease and aging

Parkinson's disease patients (N = 41, mean age = 65 years) were described by themselves and their spouses as they were presently and before their illness using the Adjective Check List. Equivalent self- and spouse descriptions were obtained from the members of a matched community sample (N = 96). Descriptions of patients and their spouses converged, both reporting sharp, pervasive (e.g., on all of the Big Five dimensions), and uniformly negative change in personality. Similar, but much less marked change was found in the community sample. The data as a set suggest that the reported changes in the patients were veridical and that their magnitude was primarily the result of the disease rather than aging. Evidence of continuities in personality (for example, differential stability) was also noted. We argued that the illness accelerated and intensified changes normally expected in later life.
