Data-Driven Approach To Dynamic Resting State Functional Connectivity In Post-Traumatic Stress Disorder, Carissa Weis
Data-Driven Approach To Dynamic Resting State Functional Connectivity In Post-Traumatic Stress Disorder, Carissa Weis
Theses and Dissertations
Posttraumatic stress disorder (PTSD) is a heterogenous psychological disorder that may result from exposure to a traumatic event. Using functional magnetic resonance imaging (fMRI), symptoms of PTSD have been associated with aberrations in brain networks that emerge in the absence of a given cognitive demand or task, called resting state networks. Most previous research in resting state networks and PTSD has focused on aberrations in the static functional connectivity among specific regions of interest (ROI) in the brain and within canonical networks constrained by a priori hypotheses. However, dynamic fMRI, an approach that examines changes in brain network characteristics over …
Exploring The Effect Of Service Dogs On Ptsd Symptoms In Veterans, Lauren Floore-Guetschow
Exploring The Effect Of Service Dogs On Ptsd Symptoms In Veterans, Lauren Floore-Guetschow
Theses and Dissertations
Utilizing psychiatric service dogs for PTSD is a relatively new area of research and treatment option for veterans. This qualitative research study aims to look at the effects of the use of psychiatric service dogs on veterans with PTSD for veterans who have or were previously receiving traditional mental health treatment. The researcher was looking to see: how does day-to-day life look for these veterans, have they noticed a change in PTSD symptoms, what are their views on mental health treatment, and how do they view being in public? 7 veterans, from a variety of conflicts and branches were interviewed …
Response To Uncertain Threat In Acute Trauma Survivors, Kenneth Bennett
Response To Uncertain Threat In Acute Trauma Survivors, Kenneth Bennett
Theses and Dissertations
Uncertainty is often associated with subjective distress and a potentiated anxiety response. The heightened response to uncertainty may be a central mechanism via which anxiety-, trauma-, and stressor-related disorders are developed and maintained. The current study compared the neural response to predictable and unpredictable threat in acute trauma survivors to clarify the role of the response to uncertain threat in fear circuitry and further inform the nature of the development of PTSD in the context of uncertain threat. The novel study showed that anticipating unpredictable (primarily negative images) relative to predictable images increased activation in a frontoparietal network and was …
Gender Role Conflict, Emotion Regulation, And Ptsd Symptom Severity In Acutely Injured Trauma Survivors, Katelyn Elaine Heyrman
Gender Role Conflict, Emotion Regulation, And Ptsd Symptom Severity In Acutely Injured Trauma Survivors, Katelyn Elaine Heyrman
Theses and Dissertations
Within the acutely injured population, men are at an increased risk for trauma exposure and hospitalization. Previous literature has suggested that emotional dysregulation and masculine gender roles are associated with psychological distress and maintenance of PTSD symptoms. Despite these findings, researchers have focused their attention on masculine gender roles within the Veteran and college populations. The current study aimed to assess the Gender Role Conflict within the acutely injured population and determine if emotion regulation strategy moderated the relationship between masculine gender roles and PTSD symptom severity. Participants consisted of 90 traumatically injured, cisgender males (Mage= 44.88 years; 60% White) …
