Cortisol Administration Normalizes Aberrant Functional Connectivity In Women With Depression, Adam C. Runyan
Cortisol Administration Normalizes Aberrant Functional Connectivity In Women With Depression, Adam C. Runyan
Dissertations
Previous resting-state functional connectivity (rsFC) research has identified aberrant connectivity in several large brain networks in depression, including the default mode (DMN), frontoparietal (FPN), and salience networks (SN). Connectivity of these networks is also related to depressive symptom severity and is affected by cortisol levels. To our knowledge, this is the first study to investigate the effects of acute cortisol administration on rsFC of DMN, FPN, and SN in individuals varying in depression history and severity. We collected resting-state fMRI scans for 74 women with and without a history of depressive disorder after administration of cortisol and placebo using a …
More Than Just Words On A Screen: A Biopsychosocial Approach To Understanding Effects Of Race-Related Media, Melinda Kittleman
More Than Just Words On A Screen: A Biopsychosocial Approach To Understanding Effects Of Race-Related Media, Melinda Kittleman
Dissertations
Racial disparities in physical and mental health are ongoing and well-documented problems in the United States. Black Americans, compared to White Americans, have higher risk of obesity, heart disease, cancer, depression, and substance abuse. Research suggests prejudice and discrimination play a role in racial health disparities. Everyday discrimination is considered a chronic, psychosocial stressor that impacts the health of Black Americans. A biopsychosocial approach states there are various factors that contribute to the pathway from discrimination to disease and proposes complex relationships that explain effects of racial discrimination on health. The current study examined social factors (race-related media), biological factors …
Redefining Burnout: Exploring Common Conceptualizations And The Neurophysiology Of Chronic Stress To Establish An Integrated Allostatic Model, Danny A. Guzzi
Redefining Burnout: Exploring Common Conceptualizations And The Neurophysiology Of Chronic Stress To Establish An Integrated Allostatic Model, Danny A. Guzzi
Dissertations
Burnout is a widely researched stress-related phenomenon associated with numerous adverse outcomes for employees and organizations. Unfortunately, burnout is not well understood and research to this point has been flawed due to a lack of consensus on the definition, dimensionality, and context of the construct. Prevalent conceptualizations of burnout have been criticized for being arbitrarily developed without solid theoretical foundation and for failing to clearly distinguish burnout from depression or other work-related conditions such as compassion fatigue, secondary traumatization, and vicarious traumatization. The current project first examines relevant literature to identify commonalities among prevalent burnout conceptualizations. Then relevant stress research …
