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.

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 …
