Differentiating anxiety and depression in older adults with generalized anxiety disorder

To examine affect and cognition in differentiating anxiety and depression, 83 older participants with generalized anxiety disorder completed the Cognitive Checklist (CCL) and the Positive and Negative Affect Schedule (PANAS). A 3-factor solution was found for the PANAS: positive affect (PA), anxiety and anger (Negative Affect 1 [NA-1]), and guilt and shame (Negative Affect 2 [NA-2]). A 2-factor structure was noted for the CCL. Correlations with anxiety and depression measures suggested that the CCL Depression (CCL-D) subscale showed stronger correlations with depression, whereas the CCL Anxiety subscale did not uniquely correlate with anxiety. The NA-1 subscale correlated positively with measures of depression and anxiety, whereas the PA subscale showed negative correlations. Hierarchical regression suggested that the CCL-D subscale was a significant predictor of self-reported depression.     

The structure and correlates of anxiety sensitivity in older adults

Anxiety sensitivity (AS) has been defined as the fear of symptoms of anxiety and panic, and is most frequently assessed with the Anxiety Sensitivity Index (Peterson & Reiss, 1987). To investigate the nature and structure of AS in an older sample, data were collected from a sample of 322 adults aged 65 to 97, with mean age 75. Confirmatory factor analysis indicated a hierarchical structure with three group factors (physical concerns, mental incapacitation concerns, and social concerns), as well as a general factor, consistent with previous investigations. Results suggest that the nature and structure of the AS trait in older adults are highly similar to those of younger adults.     

Stage of exercise change model and attitudes toward exercise in older adults.

This study examined the attitudes toward exercise held by older adults within different stages of the exercise change model for the purpose of aiding health professionals in developing effective approaches that engage older adults in physical activity. Men and women (n = 116) between the ages of 60 and 93 years (73.9+/-6.6) completed a questionnaire used to categorize them into one of five stages of exercise change: precontemplation, contemplation, preparation, action, and maintenance. Participants also completed a questionnaire to assess four attitude factors related to exercise: tension release, health promotion, vigorous exercise, and social benefits. The Active older adults in this study reported positive attitudes toward exer cising for health benefits, social interaction, and tension release. Of these, the health benefits of exercise appear to be the most important factor in their participation in exercise. Therefore, prograns designed to engage older adults in regular physical activity should promote positive attitudes toward exercise, especially regarding the health related aspects of exercise.     

Measures of self-efficacy and optimism in older adults with generalized anxiety

This study provides initial psychometric data for the Self-Efficacy Scale (SES) and the Life Orientation Test (LOT) in a sample of older adults with generalized anxiety disorder (GAD). Participants included 76 adults, ages 60 to 80, who met Diagnostic and Statistical Manual of Mental Disorders (4th ed.) criteria for GAD. Self-efficacy and outcome expectancies were lower in older adults with GAD relative to published data from younger and older community samples. Both the SES and LOT demonstrated adequate internal consistency. Confirmatory factor analysis provided evidence for optimism and pessimism factors within the LOT and exploratory factor analysis of the SES suggested threefactors that overlap with previous findings. Overall, the data support the potential utility of these instruments in late-life GAD and set the stage forfuture investigations of generalized self-efficacy expectancies and outcome expectancies (or optimism) as they relate to the prediction of affect and behavior in this group.     

Hemispheric asymmetry reduction in older adults: the HAROLD model

A model of the effects of aging on brain activity during cognitive performance is introduced. The model is called HAROLD (hemispheric asymmetry reduction in older adults), and it states that, under similar circumstances, prefrontal activity during cognitive performances tends to be less lateralized in older adults than in younger adults. The model is supported by functional neuroimaging and other evidence in the domains of episodic memory, semantic memory, working memory, perception, and inhibitory control. Age-related hemispheric asymmetry reductions may have a compensatory function or they may reflect a dedifferentiation process. They may have a cognitive or neural origin, and they may reflect regional or network mechanisms. The HAROLD model is a cognitive neuroscience model that integrates ideas and findings from psychology and neuroscience of aging.     

In the zone: flow state and cognition in older adults

The current study investigated the nature of the flow state among older adults. Flow is a pleasurable experiential state that occurs during full-capacity engagement in which an individual is performing at a level that is matched with the demands of the task. Each participant completed a scale assessing dimensions of flow in a particular activity selected by the participant. More cognitively demanding activities elicited higher levels of flow for those with higher fluid ability, but lower levels of flow for those with lower fluid ability. This pattern was reversed for activities that were low in demand. Our data highlight the potential importance of considering motivational states such as flow in understanding cognitive optimization in adulthood.     

Relationships between physical exercise and cognitive abilities in older adults

We investigated relationships between physical exercise and the cognitive abilities of older adults. We hypothesized that the performance of vigorous exercisers would be superior to that of sedentary individuals on measures of reasoning, working memory, and reaction time. We gave a series of cognitive tasks to 62 older men and women who exercised vigorously and 62 sedentary men and women. Multivariate and univariate analyses of variance, with age and education as covariates, indicated that the performance of the exercisers was significantly better on measures of reasoning, working memory, and reaction time. Between-group differences persisted when vocabulary, on which the performance of exercisers was superior, was used as a third covariate. Subsequent analyses showed that neither self-rated health, medical conditions, nor medications contributed to the differences between exercise groups. Results suggest that the possible contribution of physical exercise to individual differences in cognition among older adults should be further investigated.     

Examining attentional biases underlying trait anxiety in younger and older adults

Previous research has not adequately assessed the independent contributions of component attentional processes to anxiety-linked biases. MacLeod and Sadler developed a novel, lexical decision task using negative and neutral word stimuli, to enable the independent measurement of attentional engagement and disengagement. Their results suggest that anxiety-linked attentional biases are associated with facilitated attentional engagement with negative information. The present study aimed to determine the replicability of these findings, with two important extensions. First, this study included positive word stimuli in the lexical decision task, to determine whether anxiety-linked attentional biases exist only towards negative information, or toward emotionally arousing information in general. Second, this study explored age-related differences in anxiety-linked attentional biases. Younger (N=32) and older adults (N=32) with both high and low trait anxiety completed the lexical decision task. The results suggest that heightened anxiety may be associated with a deficit in engaging with positive words. No age-related differences in anxiety-linked attentional biases were apparent.     

Assessment of anxiety in older adults: a community-based survey and comparison with younger adults

The reliability and validity of existing anxiety self-report scales in elderly adults has not been adequately established, and the phenomenology of anxiety in older adults is largely unknown. In the present study, three anxiety scales and measures of depression and somatization were used to compare symptoms between older (n = 84, mean age = 75.3) and younger (n = 48, mean age = 40.3) community-dwelling adults. Results showed that the anxiety scales demonstrated good internal consistency in both age groups, although the reliabilities of the Fear Questionnaire subscales ranged from poor to good. Convergent and divergent validity were found to be variable in the older group, but this may reflect differences in anxiety as it occurs in older persons rather than psychometric problems. Anxiety symptoms did not vary with age, and levels of anxiety also remained constant. However, gender differences were found only within the older age group, with women reporting more anxiety than men. Findings are discussed with respect to current conceptualizations of anxiety in older people, as well as implications for future research.     

Evidence of differential stability of state and trait anxiety in adults

This study used Structural Equation Modeling (SEM) to assess the differential longitudinal stabilities of state and trait anxiety. In 1985 and 1987, 227 adult volunteers (ages 22-78) rated themselves on established state and trait questionnaires. In addition, aggregated-state anxiety was measured by self-rated frequency of state anxiety experienced over the previous month. Analysis of split-half subscales from single Trait and State Anxiety scales showed the State Anxiety true score factor to have a significantly lower unstandardized autoregression coefficient (.57 vs. .91), indicating less longitudinal stability. Additional models found longitudinal factor correlations .90, .72, and .66 for Trait, Aggregate-State, and State Anxiety, respectively, further establishing the differential stability of each. There were no significant age differences in longitudinal stability or in within-occasion state-trait factor correlations.     

Social anxiety in older adults: phenomenology, prevalence, and measurement

Although phobias represent the most common anxiety disorders among the elderly, little is known about their social nature. The present study provides information about the prevalence, measurement, and phenomenology of social anxiety in older adults (n = 283) and compares results to those of younger adults (n = 318). Analyses revealed that social anxiety is less prevalent in old age than it is within younger cohorts and is associated with different symptomatology. The psychopathological profile of those who reach clinical levels of social anxiety is however similar, irrespective of age. Results regarding the psychometric properties of the SPAI when used for the elderly were promising, but the questionnaire appears to be difficult for some older adults to complete. Results are discussed in terms of explanations for age differences in social anxiety, initial psychometrics of the SPAI in an older adult sample, and suggestions for future research.     

Gender differences in social support among older adults

The purpose of this study was to determine whether exposure to life stress can help explain gender differences in the use of social support. Findings from a longitudinal study suggest that as the number of stressful life events increase, elderly men and women are equally likely to become more involved in their social network, while gender differences emerge only in response to chronic financial strain. Further analysis indicates that elderly women are more likely than elderly men to report that the support they received increased their feelings of personal control.     

Urinary incontinence and psychological distress among older adults

We examined the relationship between urinary incontinence and psychological distress in a sample of community-dwelling older adults. The data are from a probability sample of Washtenaw County, Michigan residents ages 60 years and older, who were interviewed in 1983 and 1984. A total of 747 women and 541 men were included in the analyses. Experiencing urinary incontinence, particularly in a severe form, was weakly related to depression, negative affect, and low life satisfaction. These relationships are partly explained by the fact that incontinent respondents are less healthy than are continent respondents.     

Influence of aerobic and stretching exercise on anxiety and sensation-seeking mood state

This study randomly assigned participants to either an aerobic, non-aerobic, or lecture group to assess whether one bout of exercise would alter mood state. Regardless of experimental condition, changes in mood state were found on the Sensation Seeking and Anxiety State Tests, where sensation-seeking scores increased and anxiety state decreased from pre- to posttest.     

Changes in childhood caregiving impressions among middle-aged and older adults

Childhood experiences and impressions are important for individuals' health and well-being—they often set the stage for how people approach relationships across the lifespan and how they make sense of their relational worlds. However, impressions of these experiences are likely not static and can change over time, even years after these experiences happened. The current study examined how impressions of parental relationships in childhood changed over time, and predictors of these changes, among middle-aged and older adults followed over a 4-year period (N = 2692; M_age = 66.67, SD = 9.15; 64.1% women). Childhood impressions of parental care were mostly stable over time, with 53.5%–65.0% of participants reporting consistent impressions. Becoming divorced/separated as an adult was associated with more negative impressions about relationships with fathers in the past. Having a mother pass away was associated with more positive impressions of mothers' caregiving when participants were children. Higher depressive symptoms at follow-up were associated with darker perceptions of the past—more negative impressions of mothers and fathers as caregivers. The current study is one of the most comprehensive studies of late-life changes in childhood impressions to date, suggesting future directions for studying the organization of relational experiences and recollection over time.     

Alternative theories of concept identification among older adults

The purpose of the present experiment was to investigate some predictions of hypothesis testing and S-R association (frequency) theories regarding memory for intratrial events on a conjunctive concept-identification task. They have received extensive study with young adults but not with older subjects. The individual events under investigation were feedback, responses, hypotheses, and stimuli. Hypothesis-testing theory requires subjects to retain information concerning the correct hypothesis from one trial to the next whereas frequency does not. 75 subjects (60-70 yr. old) participated in the study. Subjects had difficulty in recalling the correct hypothesis stated on previous trials. These errors occurred on problems with negative response trials, not with incorrect feedback. The results contradict predictions based on hypothesis-testing models but are consistent with frequency theory. Unlike in the studies based on younger adults, present subjects did not recall the hypothesis very well under the conditions in which hypothesis testing was made part of the primary task.     

Activation of emotion information in text among younger and older adults

The ability to represent emotions is an important capacity for the understanding of discourse. In the current literature, it is unclear whether older adults represent emotion information in the course of language processing, in particular as it relates to developing an adequate mental model of characters in narratives. We addressed this issue in two studies, one assessing emotion activation at the word level and the other at the mental model level. In the first experiment, subjects performed a lexical decision task in which words were drawn from both logic- and emotion-based categories. For both category types, priming was evident for young and old. In the second experiment, subjects read passages with emotion information that was consistent or inconsistent with the implied emotional tone. Both age groups showed an increase in reading time in response to inconsistent emotion information, indicating that the protagonist's emotional state was represented while reading. Results of these studies generally suggest age preservation in the activation of emotion information in language processing.     

Long-term concentrative meditation and cognitive performance among older adults

ABSTRACT

Background: The general consensus that cognitive abilities decline with advancing age is supported by several studies that have reported that older adults perform more poorly on multiple tests of cognitive performance as compared to younger adults. To date, preventive measures against this cognitive decline have been mainly focused on dietary, physical, and lifestyle behaviors which could allow older adults to maintain their cognitive abilities into late life. However, much less stress has been laid on evaluating meditation as a preventive measure in such cases in spite of the fact that the role of meditation on attention has been proved in several studies. In the current study, we extend this preliminary idea, examining the practice of concentrative meditation and the differences in the cognitive performance of older adults who have or have not employed this practice long term. Methodology: This was a cross-sectional study comparing the cognitive performance of meditators and non-meditators in the geriatric age group. Twenty (age > 55 years) long-term practitioners of Vihangam Yoga meditation (>10 years of practice) were recruited in the present study and were applied six paper–pencil neuropsychological tests for assessment of short-term memory, perceptual speed, attention, and executive functioning. The tests used were: (1) the Digit Span test, (2) the Stroop Color Word test, (3) the Trailmaking test, (4) the Letter Cancellation Task, (5) the digit symbol substitution test, and (6) the Rule Shift Card Test. All the tests were also applied to 20 age- and education-matched geriatric adults who have not practiced the meditation technique. Results: Vihangam Yogis showed significantly better performances in all these tests of attention (p < .05) except for the digit backward test, where a trend (p = .08) was found in favor of meditators. Conclusion: Long-term Vihangam Yoga meditators have superior cognitive abilities than non-meditators in the old age group. This technique should be studied further for its ability to prevent age-related cognitive decline.     

The impact of coping and resilience on anxiety among older Australians

Objective: This study aims to explore the relationships between various coping types, resilience, and anxiety among older Australians. Particular attention is paid to whether resilience moderates coping's effect on anxiety. Method: A total of 324 Australians aged between 55 and 90 (M = 66.7, SD = 8.6) were surveyed as part of the study. Moderation was assessed using structural equation modelling and plots of simple slopes. Results: Significant negative correlations were detected between anxiety and both proactive coping and preventive coping. Higher levels of resilience were associated with lower levels of anxiety. Age moderated both proactive coping and reflective coping's effects on anxiety and gender moderated avoidance coping's effect on anxiety. Resilience was found to moderate the relationships between proactive coping and anxiety, and instrumental support seeking and anxiety. For those high in resilience, there was little association between anxiety and proactive coping or anxiety and instrumental support seeking. Among low resilience individuals, there was a negative association between proactive coping and anxiety, but a positive association between instrumental support seeking and anxiety. Conclusion: Resilience, proactive coping, and preventive coping are all important predictors of anxiety among older people. Among those who are low in resilience, proactively coping with stress may be particularly important for good mental health. The results of the study highlight the complexity of the relationship between resilience, coping, and anxiety among older people.
