Cognitive functioning of older people in relation to social and personality variables.

Age differences in performance on memory measures and in subjective ratings of memory adequacy were examined in the context of 12 social, personality, adjustment, and lifestyle measures. Participants were 285 men and women, aged 65 to 93, of middle- and working-class backgrounds. A series of multivariate and univariate analyses revealed that a large proportion of the age differences and virtually all of the social-class differences on memory measures could be accounted for by contextual variables, with education, intellectual activity, extroversion, neuroticism, and lie scores (on the Eysenck Personality Inventory) all accounting for more of the variance in memory performance than did age. Self-rated memory adequacy was not correlated with performance, and although the expected finding of lower ratings by older participants was obtained with the working-class group, the opposite was true for the middle-class group. Implications of these results for understanding age differences in memory are discussed.

Structural equation model of intellectual change and continuity and predictors of intelligence in older men

This study examined the effects of abilities as a young adult, an engaged lifestyle, personality, age, and health on continuity and change in intellectual abilities from early to late adulthood. A battery of measures, including a verbal and nonverbal intelligence test, was given to 326 Canadian army veterans. Archival data provided World War Two enlistment scores on the same intelligence test for this sample: Results indicated relative stability of intellectual scores across 40 years, with increases in vocabulary and decreases in arithmetic, verbal analogies, and nonverbal skills. Young adult intelligence was the most important determinant of older adult performance. Predictors for verbal intelligence were consistent with an engagement model of intellectual maintenance but also indicated the importance of introversion-extraversion and age. Nonverbal intelligence in late life was predicted by young adult nonverbal scores, age, health, and introversion-extraversion.

Caregiving and Dementia: Predicting Negative and Positive Outcomes for Caregivers.

A sample of 118 caregivers, maintaining relatives with dementia at home, were interviewed and completed questionnaires at initial and follow-up assessment six months later. All dependents received a cognitive assessment. The results of LISREL analysis of the data supported a model of caregiving in which negative outcomes of burden and impaired health reduced positive outcomes of enjoyment of aspects of caregiving. Caregivers with larger social support networks were more satisfied with their support, reducing feelings of impaired health, although as caregiving became more difficult, satisfaction with support decreased. The retrospective perception of the premorbid relationship as more difficult lead to the appraisal of the patients symptoms as presently being more extensive and increased burden. Women caregivers repotted both greater feelings of burden and more aspects of caregiving as enjoyable.

The role of psychosocial context, age, and intelligence in memory performance of older men

The hypothesis that psychosocial contextual factors contribute to developmental changes in memory was examined using 326 male World War II veterans. Availability of young adult intelligence scores made it possible to separate the contributions of contextual variables and age to maintenance of general intelligence from their direct contributions to performance on 4 memory tasks. Being younger, healthier, more educated, more introverted, more intellectually active, and more satisfied with social support predicted less intellectual decline and, indirectly, better memory performance. Age, personality, locus of control, and extent of social support directly contributed to performance on 1 or more memory tasks. Age contributions were consistent with Craiks (1986) proposed continuum of task demands for self-initiated effort. Possible elaborations of Craiks hypothesis to accommodate contextual variables are suggested.

Personality Traits as Determinants of Burden and Health Complaints in Caregiving.

This study tested predictions specifying the influence of caregiver personality traits on negative outcomes of caregiving, health complaints and burden. Two-hundred and thirteen caregivers, who were caring for family members with dementia, were interviewed and their relatives were assessed on cognitive status and aggression. At follow-up conducted twenty-four months later, forty-five caregivers were still continuing to provide home care for their dependents. Caregivers who scored higher on a measure of neuroticism experienced higher levels of burden and health complaints both at initial and follow-up assessment. Caregiver extraversion-introversion did not influence the experience of caregiving. At both initial and final assessment, the ability to enjoy some aspects of caregiving, recreational activities, and satisfaction with social support from family and friends mitigated negative outcomes of caregiving, while appraising the dependent as more troublesome increased negative outcomes. Caring for more cognitively impaired and more aggressive dependents and being female increased negative outcomes initially. Personality traits and most other study variables demonstrated significant continuity across time for caregivers continuing home care.

Measurement of Activity in the Elderly: The Activities Checklist

This study assessed the reliability and validity of the Activities Checklist (Reid & Ziegler, 1981) as well as its utility for predicting cognitive functioning in the elderly. Data were drawn from two longitudinal projects where elderly subjects had been tested on two occasions approximately five years apart. Test-retest reliabilities were .54 and .43 for the larger ( N = 158) and smaller ( N = 76) samples respectively. Validity was demonstrated by an age shift towards more passive activities and by positive correlations with education, occupational status, health and well-being. Weighted versions of activity scores were not superior to unweighted versions as predictors of cognitive functioning. For both samples activity levels significantly predicted performance on some cognitive measures. It was concluded that the Activities Checklist is a potentially useful instrument to employ in the study of individual differences in cognitive aging.

Retirement, Personality, and Life Satisfaction: A Review and Two Models

This article reviews the literature of life satisfaction in retirement, focusing on the retirees personality. Personality effects are examined in a context including other determinants of life satisfaction: involuntary retirement, stress, health, finances, and activities, and issues of control and adaptivity are explored. Heuristic models specifying direct and indirect effects of personality traits on life satisfaction in retirement are proposed. The models are based on the findings reviewed and on a variety of theories, including five-factor personality theory, stress theory, and attachment theory. Directions for retirement counseling, planning, and research are suggested.

Repeat Abortion: Is It a Problem?

As the number of Canadian women who have had induced abortions increases with each succeeding year, the number at risk--and the actual incidence--of repeat abortion also increases. Some researchers have argued that women who have more than one induced abortion are less well adjusted, others that they are less willing to use contraceptives, perhaps because of anxiety about sexuality. Still others have suggested that repeat abortion is unrelated to the psychology or attitudes of individual women, but rather is an inevitable result of imperfect contraceptives, imperfect contraceptive practice and the availability of legal abortion for the termination of unwanted pregnancies. A group of 580 women seeking abortions were interviewed at the Montreal General Hospital and given a number of psychological tests. About one in five of these women were having repeat abortions. The women having repeat abortions were older, less likely to be married and more tolerant of legal abortion than were women having their first abortions. They also had intercourse more frequently than the first-abortion patients. Women obtaining a repeat abortion were slightly more likely to have been using contraceptives at the time they became pregnant, but they did not differ from first-abortion patients in the types of methods that they used. On no other social or demographic characteristics, measures of psychological adjustment or attitudes about sexuality were there any important differences between the groups. A more complex statistical analysis reveals that the two most important factors differentiating first-abortion and repeat-abortion patients are age and coital frequency--both of which are variables that reflect added exposure to the risk of unintended pregnancy.(ABSTRACT TRUNCATED AT 250 WORDS)

13 Interactions Between Personality and Cognition and Their Implications for Theories of Aging

Publisher Summary This chapter discusses the interactions between personality and cognition and their implications for theories of aging. Current research on the development of personality and cognition during adulthood increasingly reflects a theoretical emphasis on contextual approaches. These approaches make the assumption that environmental contexts are important determinants of the development both of personality and of cognitive abilities. The processes underlying development are thus viewed as a lifelong series of mutually-causal interactions between the individual and the environment. These theoretical approaches emphasize the variability or plasticity of development, although the continuity of development is also well recognized. Adult characteristics are regarded not as the inevitable outcome of a developmental trajectory determined earlier in life, but are thought of rather as reflecting and shaping the environmental exchanges in which the individual engages in an attempt to maintain a sense of continuity throughout life.

The influence of psychological and situational factors on the contraceptive behavior of single men: a review of the literature.

The study of contraceptive behavior has focused on women with relatively few studies examining the psychological and situational factors that influence male contraceptive behavior. A review of empirical studies indicates the importance of the personality variable of sexual anxiety and the cognitive variables of attitudes toward contraception and sex roles in influencing the contraceptive behavior of single males. However, the situational variable of having an established sexual relationship is the best predictor of whether contraception is used. Although the contributions of attitude and utility theorists have been of substantial assistance in understanding the contraceptive behavior of married couples, the affect-reinforcement theory appears to be more applicable to contraceptive behavior in general. An analysis of the socialization of males and females in terms of utility theory also helps explain the relative failure of adolescent couples in contraception.
