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 …

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 …

Evaluation Of Telehealth Training To Teach The Stimulus Identification Questionnaire And Multiple Stimulus Without Replacement, Andrea Perez

Dissertations

The field of behavioral gerontology has seen a paucity in literature within the past 15 years focused on updating training technology and teaching best practice skills to staff. Specifically, there is a need to expand the breadth of training research focus areas could more broadly the elderly population (e.g., increasing engagement), to ensure that trainings are designed to equip caregivers with the skills to be independent, and finally, given the frequent staffing challenges experienced by aging settings (Harrington et al., 2020), to explore effective and efficient training techniques that are alternatives to lengthy, in-person training modalities. Given the personnel challenges, …

The Biological, Psychological, Cognitive, And Social Perspectives On Aging: The Design Of A Healthy Aging Program For Older Adults, Melissa Santiago

Dissertations

Aging is an inevitable process, accompanied by changes in physiological, cognitive, psychological, and social facets. Researchers have investigated the physiological, cognitive, psychological, and social risk factors associated with aging and have encouraged the use of physical activity, cognitive training, and dietary interventions to alleviate risk factors. However, holistic programs dedicated to promoting successful aging among older adults are uncommon. This review sought to promote successful aging by identifying physiological, cognitive, psychological, and social risk factors that affect older adults and develop a comprehensive program to holistically mitigate these risk factors. Risk factors associated with unsuccessful aging include the development of …

The Impact Of Traumatic Brain Injury On Neuropsychological Functioning And Tau Accumulation Later In Life In Military Veterans, Lindsay Eatman

Dissertations

Abstract The following study examines aging veterans that experience a TBI while in service and

compares to older veteran without a history of TBI. The objective is to look at cognitive profile later in life for military veterans with moderate to severe TBI different and compared to older veterans with no history of TBI. Is there a difference in tau accumulations on neuroimaging in military veterans with moderate to severe TBI compared to older veterans without a history of TBI? What is the relationship between the cognitive profile and tau imaging correlates for military veterans with moderate to severe TBI …

The Influence Of Stressful Life Events On The Development Of Type 2 Diabetes, Joshua Minks

Dissertations

This study examined the relationship between distress and the development of Type 2 diabetes mellitus (T2DM) in the presence of established risk factors. Distress secondary to mental health disparities, stressful life events, and work conditions has been shown to promote insulin resistance and the development of T2DM.

Subjects (N=79) diagnosed with T2DM within the previous six months were recruited from SSM Health Centers and VA Medical Centers in the greater St. Louis area. They completed the Recent Life Changes Questionnaire, ENRICHD Social Support Instrument, and a demographic survey and analyses were conducted to determine differences between the veteran …

Assessment For Mild Cognitive Impairment: Striving For Best Practice, Julie Leigh Dalmasso

Dissertations

This dissertation is a series of three studies aimed at determining the best assessment practices for mild cognitive impairment (MCI) that can employed by speech-language pathologists (SLPs). The first study was non-experimental and descriptive examining whether three commonly used assessment instruments yielded similar categorical results. The data were analyzed to determine whether the Eight-Item Interview to Differentiate Aging and Dementia (AD8), the Mini-Mental State Examination (MMSE), and the Cognitive-Linguistic Quick Test (CLQT) identified the same participants from a neurotypical sample as having cognitive deficits. Very little agreement was found amongst the three tools.

Study two was modified to include two …

Vascular Risk, Functional Connectivity, And Episodic Memory In Older Adults, Elizabeth Regina Tuminello Hartman

Dissertations

Resting-state functional magnetic resonance imaging and functional connectivity (FC) analyses are used to explore functional brain networks underlying a diverse array of abilities. Functional networks are composed of regions throughout the brain whose activity is closely linked to form a coherent network. One functional network, the "default mode network" (DMN), is thought to subserve self-referential thought and autobiographical memory. DMN regions include the ventromedial prefrontal cortex, inferior parietal lobe, hippocampus, and the primary "hub" of this network, the posterior cingulate cortex (PCC). For reasons yet unknown, DMN FC declines in aging, which is associated with memory impairment. Vascular risk may …

Diffusion Tensor Imaging And Neuropsychological Performance In Insulin Resistant Individuals, Elizabeth M. Lane

Dissertations

The current study sought to understand relationships between insulin resistance (IR), diffusion tensor imaging (DTI), and cognitive performance. It was hypothesized that IR would have a negative impact upon white matter and cognition. It was predicted that the uncinate fasciculus would be the most severely impacted, and this in turn would affect executive function and memory. Aim: The purpose of the study was to determine the impact of IR on white matter brain integrity among cognitively normal older adults using DTI and neuropsychological test performance. Background: The prevalence of IR has increased with growing incidence of obesity and older aged …
