Long-term antecedents and outcomes of perceived control

Perceived control plays an important role in shaping development throughout adulthood and old age. Using data from the adult lifespan sample of the national German Socio-Economic Panel (SOEP; N > 10,000, covering 25 years of measurement), we explored long-term antecedents, correlates, and outcomes of perceived control and examined if associations differ with age. Targeting correlates and antecedents of control, findings indicated that higher concurrent levels of social participation, life satisfaction, and self-rated health as well as more positive changes in social participation over the preceding 11 years were each predictive of between-person differences in perceived control. Targeting health outcomes of control, survival analyses revealed that perceived control predicted 14-year hazard ratio for disability (n = 996 became disabled) and mortality (n = 1,382 died). The effect for mortality, but not for disability, was independent of sociodemographic and psychosocial factors. Overall, we found very limited support for age-differential associations. Our results provide further impetus to thoroughly examine processes involved in antecedent-consequent relations among perceived control, facets of social life, well-being, and health.     

A Longitudinal Investigation of Perceived Control and Cognitive Performance in Young,Midlife and Older Adults

ABSTRACT

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.

Glycosylated Hemoglobin Level,Race/Ethnicity,and Cognition in Midlife and Early Old Age

Empirical evidence linking racial/ethnic differences in glycosylated hemoglobin levels (HbA1c) to cognitive function in midlife and early old age is limited. We use biomarker data from the Health and Retirement Study (HRS, 2006–2014), on adults 50–64 years at baseline (57–73 years by 2014), and fit multinomial logistic regression models to assess the association between baseline HbA1c, cognitive function (using Langa–Weir classifications) and mortality across 8 years. Additionally, we test for modification effects by race/ethnicity. In age- and sex-adjusted models high HbA1c level was associated with lower baseline cognition and higher relative risk ratios (RRR; vs. normal cognition) for cognitive impairment no dementia (CIND; RRR = 2.3; 95%CI = [1.38;3.84]; p < .01), and dementia (RRR = 4.00; 95%CI = [1.76;9.10]; p < .01). Adjusting for sociodemographic, behavioral risk factors, and other health conditions explained the higher RRR for CIND and attenuated the RRR for dementia by approximately 30%. HbA1c levels were not linked to the slope of cognitive decline, and we found no evidence of modification effects for HbA1c by race/ethnicity. Targeting interventions for glycemic control in the critical midlife period can protect baseline cognition and buffer against downstream development of cognitive impairment. This can yield important public health benefits and reductions in burdens associated with cognitive impairment, particularly among race/ethnic minorities who are at higher risk for metabolic diseases.     

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.     

Primary and secondary control strategies for managing health and financial stress across adulthood

The study examined the relation among three types of control strategies (persistence, positive reappraisals, lowering aspirations) and subjective well-being across adulthood (N = 3,490). Specifically, the authors investigated whether age-adapted endorsement of control strategies is conducive to subjective well-being if individuals experience health or financial stress. The results reveal an overall enhanced reliance on control strategies in older as compared with younger adults. In addition, persistence showed a stronger positive relation to subjective well-being in young adulthood as compared with old age. In midlife and old age, positive reappraisals had a stronger positive relation to subjective well-being than persistence. Lowering aspirations was negatively related to subjective well-being, independent of age. Age differences in the relation of control strategies to subjective well-being were particularly salient in individuals who faced either health or financial stress.     

Brain training in older adults: evidence of transfer to memory span performance and pseudo-Matthew effects

In this study the effects of 'brain training' using the Nintendo DS Brain Training program were examined in two groups of older adults; the cognitive performance of an experimental group (n = 21) who were asked to use the Nintendo DS regularly over a 6-week period was compared with the control group (n = 20). Groups were matched on age (mean age = 74 years), education, computer experience, daily activities (time spent reading or watching television), and initial scores of Wechsler Adult Intelligence Scale. Analyses revealed that improvements were primarily in the Digit Span Test, specifically Digits Backwards. Although the Brain Training package appeared to have some efficacy, other factors such as perceived quality of life and perceived cognitive functioning were at least equally important in determining training outcomes. The implications of these findings for cognitive training are discussed.     

The effect of perceived control on self-reported cardiovascular disease incidence across adulthood and old age

Objective: To examine whether rates of change in perceived control are predictive of cardiovascular disease (CVD) incidence across adulthood and old age.

Design: We used the PATH Through Life Project (n = 7103, M = 40, SD = 16; 52% women), a longitudinal panel survey that encompasses three cohorts at Time 1, ages 20–24, 40–44 and 60–64, who have been assessed three times at four-year intervals.

Method: We examined whether rates of change in perceived control were associated with CVD incidence over 8 years of time, over and above that of baseline levels of perceived control and known risk factors for CVD.

Main Outcome Measures: Self-reported CVD incidence.

Results: Increases in perceived control over time were associated with decreased likelihood of 8-year incidence of CVD and these effects were independent of socio-demographics, covariates and baseline levels of perceived control. The effects were consistent across young adulthood, midlife and old age and for men and women.

Conclusions: Findings demonstrate the importance of changes in perceived control as a predictor of CVD incidence across adulthood and old age. We suggest future research using mediation analysis to test reverse causality and mechanisms underlying the effects of perceived control on CVD incidence.     

Self‐esteem trajectories across 25 years and midlife intimate relations

Guided by a life‐span developmental systems approach, this study examined links between self‐esteem assessed over 25 years and adaptive interaction and relationship risk at midlife using data from 341 Canadian adults surveyed (or followed) from ages 18 to 43. Results showed higher self‐esteem at age 18 was associated with more adaptive interactions and lower perceived relationship risk at age 43. A more rapid increase in self‐esteem through the transition to adulthood into midlife (ages 18–43) was also associated with more frequent adaptive interactions and less relationship risk at age 43. These results held after accounting for potential confounding variables. This study is the first to demonstrate self‐esteem trajectories over a quarter century predict midlife intimate relationship functioning.     

A dynamic investigation of cognitive dedifferentiation with control for retest: evidence from the Swiss Interdisciplinary Longitudinal Study on the Oldest Old

Empirical examinations of the hypothesis of dedifferentiation of cognitive abilities in old and very old age (a) do not account for possible retest effects, which consequently may yield biased estimates of age effects, and (b) focus on time-independent relations (e.g., number of latent constructs, correlations between latent or measured variables). The authors applied a structural equation model with statistical control for retest effects to investigate the dynamic relations between a marker of perceptual speed (cross out) and a marker of verbal fluency (category-fruits). Longitudinal data are from 5 waves of the Swiss Interdisciplinary Longitudinal Study on the Oldest Old (N = 377, baseline age range = 79.5- 84.5 years). The authors found that, independently of retest effects, performance on the cross-out task affected changes in performance on the category task while the opposite did not hold true. This analytical technique could be applied to various markers of broad fluid-mechanic and broad crystallized-pragmatic components of cognition.     

Cumulative trauma and midlife well-being in American women who served in Vietnam: effects of combat exposure and postdeployment social support

Background and Objectives: Research increasingly demonstrates that trauma exposure can have cumulative effects, yet much remains to be learned about effects of cumulative trauma, particularly regarding longer term adjustment. One such trauma, combat exposure, is insufficiently understood, especially for women, who are increasingly engaged in professional combat activities. Design: The study comprised a cross-sectional survey assessing multiple aspects of current well-being in women approximately 25 years after their service in Vietnam during the Vietnam War. Methods: Participants were 1374 women (78% military and 22% nonmilitary; mean age = 59.7). This study investigated the relations between three separate categories of trauma exposure (childhood, adulthood, and combat) and well-being and examined whether perceived social support at return from Vietnam moderated the association between combat exposure and well-being. Results: While both childhood and adulthood trauma exposure related to midlife well-being, combat exposure still uniquely predicted outcomes. Further, postdeployment perceived social support moderated the association of combat and well-being: recollected higher perceived social support at homecoming buffered participants from the links between combat exposure and well-being. Conclusions: These results may have important implications for interventions to reduce the impact of traumatic experiences, particularly in light of the increasing exposure of women to direct combat events.     

Mechanisms by which childhood personality traits influence adult health status: educational attainment and healthy behaviors.

OBJECTIVE: The purpose of this study was to test a life span health behavior model in which educational attainment and health behaviors (eating habits, smoking, and physical activity) were hypothesized as mechanisms to account for relations between teacher ratings of childhood personality traits and self-reported health status at midlife. DESIGN: The model was tested on 1,054 members of the Hawaii Personality and Health cohort, which is a population-based cohort participating in a longitudinal study of personality and health spanning 40 years from childhood to midlife. OUTCOME: Childhood Agreeableness, Conscientiousness, and Intellect-Imagination influenced adult health status indirectly through educational attainment, healthy eating habits, and smoking. Several direct effects of childhood traits on health behaviors and health status were also observed. CONCLUSION: The model extends past associations found between personality traits and health behaviors or health status by identifying a life-course pathway based on the health behavior model through which early childhood traits influence adult health status. The additional direct effects of personality traits indicate that health behavior mechanisms may not provide a complete account of relations between personality and health.     

Anxiety sensitivity and perceived control over anxiety-related events: evaluating the singular and interactive effects in the prediction of anxious and fearful responding to bodily sensations

The present investigation examined the singular and interactive effects of anxiety sensitivity and perceived control over anxiety-related events in the prediction of panic symptoms using a CO(2)-enriched air biological challenge. Two hundred and twenty-nine adult participants (M(age)=21.02, SD=7.55, 124 females) were recruited from the greater Burlington, Vermont community. Results indicated that pre-challenge anxiety sensitivity, but not perceived control over anxiety-related events, significantly predicted post-challenge panic attack symptoms, anxiety focused on bodily sensations, and, interest in returning for another challenge (behavioral avoidance). In regard to physiological findings, anxiety sensitivity was significantly related to skin conductance level whereas perceived control over anxiety-related events was related to respiration rate. Neither anxiety sensitivity nor perceived control over anxiety-related events was related to heart rate. There also were no interactive effects between anxiety sensitivity and perceived control over anxiety-related events for any of the studied dependent variables. Results are discussed in relation to multi-risk factor models of cognitive vulnerability for panic psychopathology.     

Hardiness and health among women with rheumatoid arthritis

The relations among hardiness (and its components) and demographic variables, objective health, disability, and perceived health were investigated for 33 women with rheumatoid arthritis. Hardiness and demographic variables were measured once while objective health, disability, and perceived health were measured at three monthly intervals. Hardiness and/or component scores were significantly (P < 0.05) related to age and to employment status but were unrelated to education and to marital status. The control dimension of hardiness was positively correlated with the average percentage of circulating T-cells (r = 0.38, P < 0.05), and with average perceived health compared to one's same age peers (r = 0.53, P < 0.01). Hardiness appears to be a useful construct for understanding adaptation to rheumatoid arthritis, and studies of patients with chronic diseases can shed light on the precursors and consequences of hardiness.     

Effects of early alcohol use on adolescents' relations with peers and self-esteem: patterns over time

Strain or problem-solving models posit that deviance persists because it enhances youths' psychosocial properties and is therefore functional for adolescents. However, empirical tests of this assumption have been limited to determining whether a moderately social activity like delinquency produces time-ordered changes in self-esteem. This research examines whether a highly social activity like alcohol use improves adolescents' relations with peers and self-esteem over time. The results of a four-year panel study show that the effects of early alcohol use are limited to enhancing peer relations only among adolescents who use alcohol in order to be part of the group. Early alcohol consumption also has a delayed effect on boosting self-esteem, but this effect is restricted to youths who equate drinking with sophistication. The lack of generality of these findings and how the psychological functions of drinking might cancel these effects are discussed.     

The effect of rebranding generic medicines on drug efficacy and side effects

Objectives: Subjective age is an important correlate of health, well-being, and longevity. So far, little is known about short-term variability in subjective age and the circumstances under which individuals feel younger/older in daily life. This study examined whether (a) older adults’ felt age fluctuates on a day-to-day basis, (b) daily changes in health, stressors, and affect explain fluctuations in felt age, and (c) the daily associations between felt age and health, stressors, or affect are time-ordered.

Method: Using an eight-day daily diary approach, N = 43 adults (60–96 years, M = 74.65, SD = 8.19) filled out daily questionnaires assessing subjective age, health, daily stressors, and affect. Data were analysed using multilevel modelling.

Main outcome measures: Subjective age, health, daily stressors, affect.

Results: Intra-individual variability in felt age was not explained by time but by short-term variability in other variables. Specifically, on days when participants experienced more than average health problems, stress, or negative affect they felt older than on days with average health, stress, or negative affect. No time-ordered effects were found.

Conclusion: Bad health, many stressors, and negative affective experiences constitute circumstances under which older adults feel older than they typically do. Thus, daily measures of subjective age could be markers of health and well-being.     

Relations of maternal socialization and toddlers' effortful control to children's adjustment and social competence

The authors examined the relations of maternal supportive parenting to effortful control and internalizing problems (i.e., separation distress, inhibition to novelty), externalizing problems, and social competence when toddlers were 18 months old (n = 256) and a year later (n = 230). Mothers completed the Coping With Toddlers' Negative Emotions Scale, and their sensitivity and warmth were observed. Toddlers' effortful control was measured with a delay task and adults' reports (Early Childhood Behavior Questionnaire). Toddlers' social functioning was assessed with the Infant/Toddler Social and Emotional Assessment. Within each age, children's regulation significantly mediated the relation between supportive parenting and low levels of externalizing problems and separation distress, and high social competence. When using stronger tests of mediation, controlling for stability over time, the authors found only partial evidence for mediation. The findings suggest these relations may be set at an early age.     

Gender Differences in Biobehavioral Aftereffects of Stress on Eating,Frustration, and Cardiovascular Responses1

Eating, persistence, and cardiovascular responses were evaluated after exposure to a 25‐min noise stressor with or without perceived control. Participants were healthy men (n = 29) and women (n = 34), aged 21 to 45 years. There were no group differences in cognitive task performance or blood pressure during the stressor. However, perceived control resulted in lower mean blood pressure and heart rate after cessation of the stressor for men and women. Women without perceived control displayed greater frustration levels following the stressor, and frustrated women ate more bland food than did nonfrustrated women. Perceived control and frustration did not affect food consumption among men following the stressor. These findings indicate that there are health‐relevant gender differences in biobehavioral responses that occur in the aftermath of stressor exposure. In addition, perceived control was especially important for women to attenuate the behavioral and biological effects of stressor exposure.     

Adaptive midlife defense mechanisms and late-life health

A growing body of research suggests that personality characteristics relate to physical health; however, this relationship has primarily been tested in cross-sectional studies that have not followed the participants into old age. The present study utilizes data from a 70-year longitudinal study to prospectively examine the relationship between the adaptive defense mechanisms in midlife and objectively assessed physical health in late life. In addition to examining the direct effect, we test whether social support mediates this relationship. The sample consisted of 90 men who were followed for over seven decades beginning in late adolescence. Health ratings from medical records were made at three time points (ages 70, 75, and 80). Defense mechanisms were coded from narratives by trained independent raters (Vaillant, Bond, & Vaillant, 1986). Independent raters assessed social supports between ages 50 and 70. More adaptive defenses in midlife were associated with better physical health at all three time points in late life. These relationships were partially mediated by social support. Findings are consistent with the theory that defense maturity is important for building social relationships, which in turn contribute to better late-life physical health. Psychological interventions aimed at improving these domains may be beneficial for physical health.     

Cognitive and social functioning across adulthood: age or student status differences?

Younger adult students between 19 and 24 years of age (M = 21.3 years), older adult students between 61 and 76 years of age (M = 67.9 years), and older adult nonstudents between 62 and 76 years of age (M = 68.5 years) were assessed for health (self-ratings of physical and mental health), social functioning (self-ratings of physical and mental activity, perceived role activity level, perceived roles, locus of control, and age-norm expectations), and cognitive functioning (Wechsler Adult Intelligence Scale-Revised vocabulary and block design, and paired associate memory). Age differences were observed in self-ratings of health, social roles, intellectual performance, and memory. No student status differences were observed. The results are discussed in terms of plasticity of intellectual function and characteristics of student status in later adulthood.
