An Examination Of The Relation Between Memory Self-Efficacy And Working Memory Within The Cognitive Reserve Framework, Genna Marie Mashinchi Ma

Graduate Student Theses, Dissertations, & Professional Papers

Dementia has been found to negatively affect multiple aspects of cognitive functioning. Despite an increasing prevalence of cognitive decline, many aging adults do not experience reduced cognitive functioning. The reason as to why some experience cognitive decline and others do not is still unclear. One leading theory thought to explain this phenomenon is the cognitive reserve theory (CR), which proposes that certain lifestyle factors (e.g., educational attainment, occupational attainment, and leisure activity participation) prolong one’s cognitive functioning and reduce the risk of cognitive decline. Memory self-efficacy (MSE), defined as one’s beliefs in their memory ability, was found to be positively …

Illness Intrusiveness And Psychosocial Adjustment Among Older Adults With Multimorbidity, Irina Mindlis

Dissertations, Theses, and Capstone Projects

Given the high prevalence of multimorbidity (MM) among older adults and the exponential growth of the older adult U.S. population, identifying factors that can lessen depressive symptoms and improve quality of life (QOL) in this population is timely and important. While it is well established that MM is associated with greater depressive symptoms and poorer QOL (Li et al., 2016; Makovski et al., 2019; Marengoni et al., 2011; Read et al., 2017), the mechanisms underlying these relationships remain understudied. The illness intrusiveness model (Devins et al., 1984) proposes that stressors posed by diseases (disease-related factors) and their treatments (treatment-related factors) …

Predictive Abilities Of Neuropsychological Measures On Functional Outcomes In The Mild Cognitive Impairment (Mci) And Dementia Populations, Morgan Bare

PCOM Psychology Dissertations

During the aging process, a decline in ability to perform everyday tasks is commonly observed. This is increasingly so for those with dementia and is a diagnostic requirement. These daily tasks require certain cognitive skills which can be measured by various neuropsychological measures. The purpose of this study is to examine which neuropsychological measures are able to detect various deficits in self-reported activities of daily living (ADL) and instrumental activities of daily living (IADL) in individuals with mild cognitive impairment (MCI) and dementia. It is hypothesized that Trail Making Test– B (TMT-B) would be the most sensitive predictor in functional …

Correlates Of Psychological Well-Being In Older Adults With Treatment-Resistant Depression, Selmi Kallmi

Dissertations

The purpose of this study was to examine the factors that are associated with psychological well-being in older adults with late-life depression and determine if social participation moderates and/or mediates these relationships. This dissertation study utilized secondary pre-treatment data collected from the “Optimum: Optimizing Depression Treatment in Older Adults” study (Cristancho et al. (2019). Community dwelling older adults (N = 369) were included if they currently met criteria for MDD, had failed at least two prior trials of MDD medication treatment, and were able to visit the study site to participate in cognitive and physical functioning assessments. Hierarchical multiple regressions …

Does Anxiety Sensitivity Mediate Age-Related Differences In Anxiety In Middle-Aged And Older Adults?, Katherine F. Peterson

Theses and Dissertations

Anxiety is a mental illness that can have significant deleterious impacts on an individual’s functioning. Although anxiety has been studied in older adults, there is conflicting evidence on differences in anxiety as a function of age. Anxiety sensitivity is a construct that is positively related to anxiety but has limited research in older adults. Extant literature suggests that older adults experience less anxiety sensitivity than do younger adults. According to Socioemotional Selectivity Theory, this may be due to older adults letting go of the things that make them anxious. The current study proposed that age impacts self-rated anxiety such that …

The Role Of Intimate Partnership Among Older Adults On Pain Severity And The Engagement In Preventative Health Behaviors, Lauren Fox

Doctoral Dissertations

Bodily pain is a frequently disabling condition among older adults, which has broad biopsychosocial implications on health and wellbeing. As adults age, diminishing support systems can result in poor health outcomes and the presence of an intimate partner relationship can positively impact physical health, including influencing pain severity. The number of adults in the United States over 65 is expected to double by 2030, meaning that a significant portion of the population will be entering a stage of increased healthcare utilization. Therefore, behaviors which improve physical health will only become increasingly important over time. While previous research has pointed to …

Personality Pathology And Cognitive Aging: The Role Of Interpersonal Stress, Patrick Joseph Cruitt

Arts & Sciences Electronic Theses and Dissertations

Research on the relationship between normal-range personality and cognitive aging has demonstrated consistent, but modest, effects. The current investigation seeks to increase our understanding of unhealthy cognitive aging by examining the maladaptive extremes of personality. Borderline and avoidant personality disorder (PD), but not obsessive-compulsive PD, were hypothesized to show prospective associations with cognitive aging. Interpersonal stress was expected to mediate these relationships. The current investigation tested these hypotheses in two longitudinal studies of older adulthood: the Alzheimer’s Disease Research Center cohort (ADRC, N = 434, Mage = 69.95, 56% women) and the St. Louis Personality and Aging Network study (SPAN, …

Impact Of Aging Information On The Continuing Education Preferences Of Behavioral Health Clinicians, Nicholas Schmidt

Dissertations

The United States population is aging rapidly and the behavioral health workforce is ill-prepared to meet the concurrent rise in demand for services for older adults. Clinicians specializing in working with older adults make up a very small portion of providers and the majority of service provision falls on general practitioners. The discipline of counseling has emphasized multicultural competencies in training and practice but has not specified standards of competence for work with older adults; little is known about the interests and training preferences of Licensed Professional Counselors (LPCs). This study examined the impact of receiving foundational information about aging …

Examining The Mental Health Of Older Hispanic/Latino Adults: Relationship Between Psycho-Social-Cultural Factors And Depressive Symptomatology, Anna Prado

Theses and Dissertations

The most prevalent disorders affecting the older adult population worldwide are dementia and depression. Ethnic minorities are disproportionately more likely to be affected by these two distressing and debilitating conditions. Hispanic/Latino older adults encounter numerous psycho-social-cultural factors that influence health behaviors, attitudes, and beliefs in positive and negative ways. Presently, research on the influence of these factors on Hispanic/Latino mental health is highly inconsistent. The purpose of the present study is to examine the relationship between selected psycho-social-cultural factors and the mental health of older Hispanic/Latino adults. Using data from the Health and Retirement Study, the association between the Hispanic/Latino …

The Relationship Between Insomnia, Sleep Continuity Disturbance, Sleep-Related Daytime Dysfunction, Problem Endorsement, And Aging In A Community-Based Sample, Julia T. Boyle

PCOM Psychology Dissertations

Although older adults experience greater difficulty initiating sleep, maintaining sleep, or waking up earlier than intended, they are less likely to report that they perceive this to be a problem. The discordance between sleep disorder symptoms and the reported perception that they are troubling is unusually prevalent among older adults. This may be problematic, in that individuals who do not perceive their sleep continuity disturbances (SCDs; difficulty falling asleep, staying asleep, or waking up earlier than intended) to be problems are less likely to seek treatment. Untreated SCD has been shown to be a risk factor for the development or …

Off-Topic Verbosity And Sustained Attention Among Young Adult And Older Adult Age Cohorts, Jessica H. Helphrey

Psychology and Counseling Theses

Off-topic verbosity (OTV) is tangential discourse with excessive and irrelevant information. Older adults have been historically labeled as having high OTV, and research has suggested that high OTV in older adults may be linked with cognitive decline. While past studies have utilized brief cognitive measures to further expound upon the links between cognition and OTV, studies have lacked consistency and lengthy measures. This study sought to elucidate the relationship between OTV and cognition in both older adult and young adult age cohorts utilizing a sustained attention measure. Young adults (n = 61; age range: 18-28, M = 20.57, SD = …

Does Aging Identity Moderate The Impact Of Experiences With Familial Ageism On Well-Being?, Emily E. Kinkade

MSU Graduate Theses

The purpose of this study was to begin investigating the effects of ageism in the family context. The current literature has documented the negative impacts that negative stereotypes and negative perceptions of aging has on older adults’ health, mortality, and well-being (Levy, 1996; Levy, 2003). However, the majority of extant research on ageism focuses on age discrimination in the workplace and in healthcare despite the majority of peoples’ time being spent in the family context. Therefore examining experiences of ageism sourced from family members merits study. Walker, Bisconti and Kinkade (in preparation) found evidence that the experience of ageism within …

The Effects Of A Cognitive Training Program For Healthy Older Adults: A Program Evaluation Study, Jacklyn Gehling

All Graduate Theses, Dissertations, and Other Capstone Projects

As one ages, some degree of cognitive decline is expected. Despite this, declines in cognitive abilities and the possibility of developing dementia are common concerns among older adults. In response to these concerns, a variety of cognitive training programs have been developed that aim to improve or maintain cognitive functioning. Previous literature has shown mixed or limited findings on cognitive changes after implementation of cognitive training. This study evaluated the effectiveness of a cognitive training program designed for older adults with no to minimal cognitive decline. The current study included 19 participants who engaged in two, one-hour long cognitive training …

The Effects Of Cognitive Training On Behavioral Functioning In Persons With Dementia, Abigail J. Dye

All Graduate Theses, Dissertations, and Other Capstone Projects

Lack of engagement in pleasant activities and negative mood are two factors that decrease quality of life (QoL) for older adults with moderate to severe cognitive impairment. As enhancing QoL has become a primary treatment outcome for individuals with cognitive impairment, investigation into the ability of nonpharmacological interventions to increase engagement and positive mood has come to the forefront of research. Cognitive training is a nonpharmacological intervention that utilizes manualized techniques with the primary goal of enhancing different areas of cognitive function. Although the cognitive benefits of the programs have been widely investigated and established, the potential benefits that cognitive …

Maladaptive Personality Traits And Health Behaviors, Health Perceptions, And Inflammatory Biomarkers In Older Adults, Joshua R. Oltmanns

Theses and Dissertations--Psychology

Traits from dimensional models of normal-range personality have been shown to predict physical health outcomes including health behaviors, health perceptions, disease, and mortality. Maladaptive traits of personality disorders may predict even more variance in physical health indicators. Dimensional models of maladaptive personality traits are replacing categorical models of personality disorder, and the five-factor model of personality disorder (FFMPD) has been shown to be a useful dimensional model of maladaptive traits. However, there has been little work investigating the criterion validity of the FFMPD for predicting physical health indicators. The present study examines FFMPD scales in the prediction of health behaviors, …

Help-Seeking For Cognitive Impairment By The Patient : The Role Of Self-Compassion., Allison J. Midden

Electronic Theses and Dissertations

Older adults represent one of the fastest growing population groups with estimates predicting global growth from 617 million in 2015 to 1.6 billion in 2050. As the aged population increases, incidence of Alzheimer’s disease (AD) and other dementias will also increase. Professionals agree that early intervention is essential for therapeutic and quality of life purposes. However, many older adults wait several months or years to seek medical help after first noticing signs of cognitive impairment. The present study seeks to identify the predictors of help-seeking for cognitive impairment by an individual for him/herself and the role that self-compassion may play …

Examining The Effects Of Stress And Age On Neural Reward Processing: Considerations For The Role Of Individual Differences In Autonomic Reactivity, William Mccuddy

Dissertations (1934 -)

Acute stress is unavoidable and may hinder basic reward processing underlying adaptive decision-making. Additionally, older adults may be at an increased risk of poor decision-making after exposure to acute stress due to age-related changes in cognitive and autonomic functioning. The current study assessed the influence of acute stress, autonomic reactivity, and age on a simple behavioral task during fMRI. Specifically, old and young adults completed a basic reward processing paradigm (i.e., where participants received monetary rewards and punishments) after exposure to acute stress (i.e., social evaluative cold pressor) or control procedure between-subjects. In the young group, differential responses for monetary …

Socioeconomically Disadvantaged Neighborhoods, Stroke Risk, And Cognition In Older Adults: A Focus On Violent Crime, Linda D. Ruiz

College of Science and Health Theses and Dissertations

Living in socioeconomically disadvantaged neighborhoods, i.e., neighborhoods with lower incomes, lower education/occupational levels, and/or higher crime, increases one’s risk of developing chronic health problems, including cardiovascular disease risk factors and stroke. These health problems are associated with reduced cognition and dementia and may help to explain disparities in brain aging. We investigated the association of neighborhood socioeconomic characteristics on stroke risk and cognitive outcomes hypothesizing that stroke risk mediates the association between the socioeconomic environment and cognitive functioning. Participants were non-demented community-dwelling older adults (N=121), ~67 years of age (50% male, 44% non-Latino Black) who underwent cognitive and medical assessments. …

Longitudinal Associations Between Functional Disability, Depression, And Suicide In Middle-Aged And Older Adults, Julie Ann Lutz

Graduate Theses, Dissertations, and Problem Reports

Suicide is a significant public health problem among older adults in the United States and around the world. There has been little research to date on longitudinal change in functional disability and depressive symptoms, both of which have been posited to be associated with suicide risk among middle-aged and older adults, and their association with death by suicide. The aims of this study were to 1) characterize longitudinal change in functional disability and depressive symptoms separately; 2) characterize the directional associations between functional disability and depressive symptoms in bivariate models; and 3) determine how different patterns of change among these …

Loneliness And Sleep Disturbance In Older Americans, Sarah C. Griffin

Theses and Dissertations

Loneliness is a risk factor for premature mortality but the mechanics of this relationship remain obscure. A potential mechanism is sleep disturbance. The present study aimed to examine the association between loneliness and sleep disturbance, evaluate loneliness as a risk factor for sleep disturbance and vice-versa, model effects between loneliness and sleep disturbance over time, and evaluate a mediation model of loneliness, sleep disturbance, and health. Data came from the 2006-2012 waves of the Health and Retirement Study, a nationally-representative study of older Americans; participants > 65 were included (n=11,400). Analyses included (i) linear regressions accounting for complex sampling and (ii) …

A Grounded Theory Qualitative Research Approach To Understanding Enduring Marriage, Heather Lucas

Clinical Psychology Dissertations

Serial monogamy developed as the salient pair bond form in earlier times due to environmental pressures of disease, famine, and death that led to relationships organized around the instrumental tasks of procreation and child-rearing. Contemporary advancements in longevity, gender equality, and contraception have shifted the culture, but the serial monogamy paradigm remains the prominent relationship paradigm in the United States today with relationships primarily ending in divorce instead of death. The negative effects of divorce on individuals, children and families suggest the need for a new paradigm for marriage, a shift from instrumentally driven serial monogamy to enduring marriage organized …

Assessing Working Memory In Mild Cognitive Impairment With Serial Order Recall, Sheina Emrani

Theses and Dissertations

Background: Working memory (WM) is often assessed with serial order tests such as repeating digits backward. In prior dementia research using the Backward Digit Span subtest (BDT) only aggregate test performance was examined. The current research tallied primacy/ recency effects; out-of-sequence transposition errors; perseverations and omissions to assess WM deficits in patients with mild cognitive impairment (MCI). Methods: Memory clinic patients (n= 66) were classified into three groups - single domain amnestic MCI (aMCI), combined mixed domain/ dysexecutive MCI (mixed/dys MCI), and non-MCI where patients did not meet criteria for MCI. Serial order/ WM ability was assessed by …

Differences In The Perceptions Of Gerotranscendence Between Certified Nursing Assistants And Older Adults, Amanda Perera

All Graduate Theses, Dissertations, and Other Capstone Projects

Many theories of aging have been proposed within the field of gerontology to explain both psychological and social changes that occur during the aging process. One of the theories is the theory of gerotranscendence, which explains that as individuals age they develop a new perspective on life that allows the aging individual to shift their conceptualization of the world, from a materialistic and rational view to a more transcendent and universal view. Previous research suggests that some behaviors associated with gerotranscendence have been misinterpreted as pathological. The purpose of this current study was to examine whether there are significant differences …

Testing A Values-Based Approach To Healthcare Decision-Making In Older Adults, Paul Jefferson Geiger

Theses and Dissertations--Psychology

Despite natural declines in physical and cognitive function, older adults maintain good emotion regulation abilities, leading to emotional wellbeing and resilience. This phenomenon can partially be explained by socioemotional selectivity theory (SST), which posits that when time is perceived as a limited resource, older adults focus attention on positive environmental stimuli to regulate emotions. Although this positivity effect maintains emotional wellbeing, it may disrupt information processing related to healthcare decision-making. Older adults request less information from their doctors, are less likely to ask for a second opinion, make their decisions more quickly, and devote more attention to positive medical information, …

Optimism And Pain Interference In Aging Women, Stephanie T. Judge

Theses and Dissertations--Psychology

Pain interferes with people's daily lives and often limits the extent to which they can pursue goals and engages in activities that promote well-being. The present study test how optimism affects and is affected by pain interference and activity among older women. Every three months for two years, middle- and older-age women (N = 199) complete daily diaries at home for a seven-day period, reporting their daily pain, pain interference, and activity. Optimism was measured at baseline and end-of-study. Multilevel models test the between- and within-person relationships among pain, optimism, pain interference and activity. Pain best predicted pain interference …

Emotion Regulation In Relation To Cognitive Functioning In The Preclinical Stages Of Dementia, Erica P. Meltzer

Dissertations, Theses, and Capstone Projects

Emotion regulation (ER) is essential for effective functioning in daily life. Research suggests that ER improves in older adulthood despite concomitant declines in cognition and the presumed neural substrates of ER. The current understanding of ER in older adulthood, and particularly of the relationship between ER and cognition in older adulthood, is limited. This is likely because the construct of ER is challenging to operationalize and, therefore, difficult to study.

The current study investigates ER in relation to cognitive functioning, specifically executive functioning and memory, in individuals with varying degrees of cognitive difficulties (i.e., in the preclinical stages of dementia). …

Stereotype Threat And Work Attitudes Of Older Workers, Cheryl A. Countryman

Walden Dissertations and Doctoral Studies

Abstract

Despite an aging U. S. workforce, age discrimination at work remains an issue. Researchers have found that beliefs about the aging process affect workers' performance and attitudes. There is little research available examining this phenomenon from the perception of older workers. The purpose of this qualitative phenomenological study was to understand the lived experiences of 7 workers aged 55 and older regarding ageism through the theoretical framework of stereotype threat theory. Research questions focused on identifying age-related stereotypes held by the participants, the influence of those stereotypes on perceptions of aging, perception of the impact of aging on job …

Mindfulness And Cognitive Aging, Elise J. Herndon

Theses and Dissertations

Mindfulness meditation involves the cultivation of a focused, pre-conceptual consciousness that enables increased present-centered awareness of internal states, cognitive processes, and external stimuli (Mikulas, 2011; Kornfield, 2010). Studies suggest that mindfulness practice affects the brain structures and cognitive processes related to fluid intelligence, and may affect fluid intelligence itself among highly experienced practitioners (e.g., Gard, Taquet, et al., 2014; Lazar et al., 2005; Ritskes et al., 2003). Fluid intelligence includes higher-order reasoning and problem-solving abilities that are independent of cultural and environmental influences. These abilities peak in young adulthood, then begin to decay (Cattell, 1987; Goldberg, 2005).

The current study …
