The Prevalence Of Moral Injury Among Veterans Diagnosed With Post-Traumatic Stress Disorder (Ptsd): Analyses By Combat Exposure, Gender, Age Group, And Military Service, Carl B. Forkner

Doctoral Dissertations and Projects

The attacks on the United States on September 11, 2001, and the ensuing wars in Afghanistan and Iraq, heralded in a new concept affecting our combat and support military personnel. This concept is known today as moral injury. Military personnel were already familiar with post-traumatic stress disorder (PTSD), whether from personal experience or from reading and training on the subject, but no training addresses the prevalence or effects of moral injury. The term moral injury (MI) was first coined by psychiatrist Jonathan Shay and his colleagues based on feedback from military and veteran patients in 1998; however, it remains that …

Visual trend analysis identified a peak in domestic violence in 2019, a stable frequency …

Investigating Racial And Ethnic Differences In Help-Seeking Recommendations And Intentions For Posttraumatic Stress Symptoms And Symptom Clusters, Josselyn Yanisbeth Telule

Master's Theses

Racially and ethnically minoritized (REM) communities experience disproportionate exposure to adverse events, including discrimination, socioeconomic disparities, justice system involvement, and limited access to healthcare. These inequities increase the likelihood of experiencing potentially traumatic events (PTEs) and developing trauma-related mental health concerns such as posttraumatic stress symptoms (PTSS). Despite this elevated risk, REM populations consistently underutilize mental health services. Although several explanations have been proposed—including differences in symptom recognition, perceived need for care, cultural values, mental health literacy, and preferred sources of support—less research has examined racial and ethnic differences in help-seeking intentions (HSI) and help-seeking recommendations (HSR), particularly in response …

Anhedonia Underlies The Association Between Childhood Unpredictability And Adult Ptsd Symptoms: Evidence From Three Independent Longitudinal Cohorts, Christopher Hunt, Laura M. Glynn, Elysia Poggi Davis, Tallie Z. Baram, Caroline M. Nievergelt, Giovanni Castillo, Christian Cortes, Christine Y. Chang, Dewleen Baker, Victoria B. Risbrough

Psychology Faculty Articles and Research

Background

Unpredictability in the child’s environment has recently emerged as a significant and unique form of early life adversity (ELA). Cross-sectional studies have linked childhood unpredictability with increased post-traumatic stress disorder (PTSD) symptoms in adults; however, no prospective studies have tested the link between childhood unpredictability and PTSD risk in later life, nor what processes, such as increased anhedonia symptoms, might mediate such risk. Here, we leveraged three distinct prospective, longitudinal cohorts to test the hypothesis that unpredictability during childhood contributes to adult PTSD via worsening anhedonia symptoms.

Methods

Participants were male service members (n=314), adult females (n=170), and adolescents …

The Use Of Virtual Reality In Ptsd Research And Practice, Kenneth B. Abrams, Lindsay Okindo, Marta E. Bacon, Yiking Skylar Yu, Sofia Santamaria Germani, Malvika Malhotra, Nancy A. Cullen

Psychology Faculty Work

In the aftermath of traumatic events such as combat, sexual violence, or a natural disaster, individuals may develop posttraumatic stress disorder (PTSD). Technological advancements in virtual reality (VR) over the past few decades have opened new avenues for improving the assessment, treatment, and understanding of PTSD. VR allows users to be immersed in interactive, computer-generated environments that simulate real-world scenarios, such as a warzone or assault location, that would be difficult or unsafe to reproduce using traditional methods. The present paper offers an overview of how VR technology has been employed in both clinical and research settings related to PTSD. …

Utilizing The Mmpi-3 To Assess Symptoms Of Ptsd In Post-9/11 Veterans, Lauren A. Worden-Baroni

Psychology Doctoral Specialization Projects

Symptoms of posttraumatic stress disorder (PTSD) are heterogeneous, and the psychological impact of trauma varies. This underlines the need for better understanding the impact of trauma on the development of psychopathology, especially in populations where traumatic stressors are more prevalent. Specifically, the current study will evaluate how the Minnesota Multiphasic Personality Inventory-3 (MMPI-3) can be used to measure psychopathology presentations among those who have been exposed to military trauma. Although there is myriad research supporting the use of other MMPI measures (e.g., MMPI-2-RF) in the assessment of trauma-related psychopathology in military populations, there is limited evidence supporting the use of …

Hawn, Natalie Merrill, Lance M. Rappaport, Christina M. Sheerin, Vasiliki Michopoulos, Silviu-Alin Bacanu, Roseann E. Peterson, Abigail Powers, Ananda B. Amstadter

Psychology Faculty Publications

Background: Posttraumatic stress disorder (PTSD) and alcohol use disorder (AUD), which are moderately heritable, frequently co-occur and contribute to significant public health burdens, particularly among economically disadvantaged urban communities. There are noted sex differences in PTSD and AUD outcomes, with evidence suggesting women have heightened susceptibility to stress-related alcohol use. Preliminary PTSD-AUD ecological momentary assessment (EMA) findings support bidirectional associations across clinical outcomes. However, no studies to date have used PTSD-AUD comorbidity models as organizing frameworks to examine the temporal ordering and stability of within-person symptom dynamics underlying the maintenance or exacerbation of PTSD and AUD symptoms, including bidirectional and …

Examining Ketamine's Differential Impact On Posttraumatic Stress Disorder Symptoms Using The Ptsd Checklist For Dsm-5, Samantha G. Gomez

Electronic Theses & Dissertations (2024 - present)

Posttraumatic stress disorder (PTSD) can be a debilitating and chronic condition. Current gold standard treatments are effective but face high dropout rates. Ketamine therapy is a promising and alternative treatment for those struggling with PTSD symptoms. Prior research has indicated significant reductions in overall PTSD symptoms. However, research regarding symptom-specific changes following ketamine therapy is limited. The present study aimed to extend previous work by MacConnel and colleagues (2025) regarding significant decreases in total PTSD Checklist for DSM-5 (PCL-5) scores following ketamine treatment at an outpatient ketamine center, as well as examine potential symptom-specific changes. A final sample of 142 …

Positive Psychology Interventions For Posttraumatic Stress Disorder (Ptsd) Among Earthquake Survivors In Nepal, Niusha Karki, Melissa C. Henry, Mark M. Leach

Trauma Counseling and Resilience

Natural disasters produce both community and individual trauma; Nepal’s 2015 and 2023 earthquakes exemplify this enduring impact. Previous literature has discussed the effects of PTSD and other mental health concerns post-disasters, providing some context to the difficulties in providing counseling services to those in need. However, little is known about unique psychological, cultural, and contextual factors in Nepal and how their influence and understanding may result in modifying traditional PTSD counseling interventions found in much of the existing professional literature. The purpose of this conceptual paper is to propose a culturally responsive, strengths-based framework that integrates positive psychology interventions, positive …

Evaluating A Self-Guided Cognitive Behavioral Coping Skills Workbook For Sexual Violence-Exposed College Students Using A Nonconcurrent, Multiple Baseline Design, Marley F. Fradley

Graduate Theses and Dissertations

College students endorse high rates of sexual violence victimization and posttraumatic stress disorder (PTSD). Help-seeking behaviors in college students are low and may be impacted by limited financial resources, competing obligations, treatment-related stigma, and features of PTSD such as avoidance, fear, and shame. Novel opportunities for sexually victimized college students to engage with trauma-focused interventions are necessary to mitigate the biopsychosocial consequences of PTSD. In a nonconcurrent, multiple baseline trial of a self-guided cognitive behavioral workbook for PTSD, sexual violence-exposed college students (N = 6) completed a 3-, 4-, or 5-week baseline period and then utilized the study workbook for …

Divine Intervention: The Effects Of Repairing Attachment Insecurities With God On Ptsd Symptomology In Adult Survivors Of Childhood Trauma, Erica M. Duckworth

Doctoral Dissertations and Projects

Childhood trauma occurs when an individual under the age of 18 survives a perceived life-threatening event. To circumvent future danger, numerous developmental changes occur in response to fear, manifesting in a multitude of symptoms. A culmination of symptoms results in Posttraumatic Stress Disorder (PTSD), a debilitating condition that arises from the hypervigilance of the brain and body to environmental stimuli. A recurring state of fear can lead to isolation, negatively affecting social interactions. Expectations of relationships, also known as attachment styles, reflect the bonds created between a child and a parent or caregiver. The quality of this foundational relationship can …

Divine Intervention Emphasized In Ptsd Treatment Strategies, Zachary R. Kuster

Doctoral Dissertations and Projects

This study examined how theological concepts might enhance PTSD treatment outcomes by challenging existing paradigms within evidence-based interventions. While some therapeutic models acknowledge the value of integrating theological concepts within treatment, little empirical evidence explains how emphasizing the theological concepts that may already exist within evidence-based strategies may enhance the overall efficacy of treatment. In this study, an experimental group received strategies emphasizing grace, hope, and forgiveness, while a control group received strategies without these emphases. The PCL-5 psychometric assessment tool was used to measure changes across two 4-week PTSD programs that incorporated 48 strategies from the same four therapeutic …

Volumetric Differences Of Thalamic Nuclei Are Associated With Posttrauma Psychopathology, Jacklynn M. Fitzgerald

Psychology Faculty Research and Publications

Background

Previous investigations of whole thalamus and thalamic nuclei volumes in posttrauma psychopathology have been sparse and limited in scope and have yielded inconsistent results. To address this, volumetric estimates of whole thalamus and thalamic nuclei were obtained from structural brain magnetic resonance imaging scans from 2058 participants across 20 worldwide sites in the ENIGMA (Enhancing Neuro Imaging Genetics through Meta Analysis) Posttraumatic Stress Disorder (PTSD) working group.

Methods

Thalamic volumes were compared in trauma-exposed participants with PTSD (n = 238), major depressive disorder (MDD) (n = 184), and comorbid PTSD+MDD (n = 618) and in trauma-exposed …

Does Spirituality Mediate Or Moderate The Adverse Effects Of Occupational Stressors On Mental Health In Law Enforcement Officers?, Erika D. Keplinger

Doctoral Dissertations and Projects

Law enforcement officers are often exposed to occupational stressors that can negatively affect their mental health and job performance. Spirituality has been thoroughly researched as a restorative method to improve physical and psychological health concerns. There has also been an increase in studies on workplace spirituality. The existing research on workplace spirituality suggests that incorporating spirituality into the workplace increases employee well-being and decreases stress and burnout. Unfortunately, research on police culture often neglects spirituality. There is little research to show how spirituality could mediate or moderate the adverse effects of mental health on law enforcement officers. This quasi-experimental, cross-sectional, …

A Qualitative Meta-Analysis Of The Experiences Of Clients In Psychotherapy For Posttraumatic Stress Disorder: An Empirically Based Process-Oriented Staged Model, Nicholas A. Pierorazio

Graduate Masters Theses

Posttraumatic stress disorder (PTSD) is prevalent and can be highly complex. Guidance for the treatment of PTSD has typically been based on quantitative meta-analyses of randomized controlled trial findings and has focused on the comparative efficacy of specific treatments, rather than how to deliver treatment. There is a need for clinical guidance that highlights moment-to-moment, in-session psychotherapy processes for psychotherapists working with clients with PTSD. In the current study, I conducted a qualitative meta-analysis, focusing on the qualitative literature investigating clients’ perspectives in order to develop an understanding of the preferences, values, and experiences of clients in individual psychotherapy for …

Honor, Courage, And Commitment: Institutional Betrayal And Military Identity In Veterans With Posttraumatic Stress Disorder, Amanda Reine Bedford-Rank

Doctoral Dissertations and Projects

Military veterans diagnosed with posttraumatic stress disorder (PTSD) experience elevated suicide risk and face unique treatment barriers; however, few studies have examined the role of military-specific constructs in shaping these barriers. This quantitative-correlational study investigated the relationship between institutional betrayal, self-stigma, military identity, and help-seeking attitudes among a sample of U.S. military veterans with PTSD (N = 142). This study also applied semi-qualitative questions to explore military-related trauma themes, PTSD literacy, neuroplasticity, PTSD perceptions, and military acknowledgment.
