Trauma Mediating The Severity Of Depressive Symptoms In Veterans With Ptsd, Meghan Curtin

Dissertations

Trauma serves as a risk factor for developing both posttraumatic stress disorder (PTSD) and depression. The purpose of this study was to examine trauma type as a mediator in the relationship between gender and severity of depressive symptoms among veterans with PTSD. The literature shows trauma type plays a role in developing PTSD and depressive symptoms. The first hypothesis was that female veterans who met the diagnostic criteria for PTSD would report higher levels of depressive symptoms than their male counterparts. The second hypothesis was that this gender difference would be partly mediated by levels of interpersonal trauma experience. Self-report …

Investigating The Differences Between Neuropsychological And Physiological Markers In A Ptsd-Only Group Among Vietnam Veterans, Ashtan Madsen

Dissertations

Individuals diagnosed with posttraumatic stress disorder (PTSD) have demonstrated extinction-resistant symptoms and long-lasting impacts on the brain’s functional activity (Krystal et al., 2017; Stark et al., 2015). PTSD illustrates a strong relationship with cognitive functioning, and research has found lower parietal and hippocampal volume and deterioration in brain function and structure, resulting in executive dysfunction, attentional deficits, mood dysregulation, and memory difficulties (Krystal et al., 2017; Stark et al., 2015; Weiner et al. 2017). Sleep has been investigated to better understand its contribution to AD pathologies as well as its impact on PTSD treatment and prognosis. Although sleep’s functions are …

Understanding The Experiences And Associated Symptomology Of Disclosers And Non-Disclosers Of Sexual Victimization, Kaitlin Carson

Dissertations, Theses, and Capstone Projects

ABSTRACT

According to the Center for Disease Control and Prevention, as many as 43% of women report experiencing some form of sexual victimization, with the highest rates occurring in emerging adulthood. It is estimated that 75% of survivors disclose this experience to someone else; the remainder of survivors keep the experience to themselves. While disclosure can be therapeutic, there are multiple factors that can complicate the disclosure process for sexual victimization survivors. There is limited research investigating why some women choose to disclose sexual victimization experiences and how their reasons may relate to psychopathology. Additionally, extant research primarily focuses on …

Peer Victimization And Post-Traumatic Stress Problems Among Latinx Youth: The Role Of Emotional Reactivity And Gender, Ashley N. Harris

College of Science and Health Theses and Dissertations

Peer victimization is widespread and well-established as a risk factor for youth; however, few studies have examined the relation between peer victimization and post-traumatic stress symptoms among ethnic minority children and adolescents. Additionally, existing studies rarely investigate potential moderators of the relation and often utilize retrospective reports of peer victimization from adults. This study expands on the Regulatory Theory of Temperament (Strelau, 2008) by examining the role of emotional reactivity on the association between peer victimization and post-traumatic stress problems. The sample includes 275 predominantly low-income, Latinx (86.5%), and Mixed-Latinx (13.4%) Chicago Public School students ages 10-14 (M = …

Sexual Violence And Psychological Distress: The Roles Of Coping Self-Efficacy, Self-Blame, Shame, Activism, And Feminism, Charlotte Strauss Swanson

Doctoral Dissertations

In the current study, we investigated potential direct, indirect, and moderated relations in the links between exposure to sexual violence and PTSD symptom severity and depression among a sample of 440 United States women who had experienced sexual assault in adulthood. We found that sexual violence exposure was both directly and indirectly related to PTSD symptom severity via less trauma coping self-efficacy, greater behavioral and characterological self-blame, and more shame. Sexual violence exposure was also indirectly related to depression via the same explanatory variables, except for behavioral self-blame. Contrary to our hypotheses, results indicated that involvement in anti-sexual activism and …

The Role Of Childhood Trauma History In Relation To Decent Work, Matthew Reiland

Theses and Dissertations

This study used structural equation modeling to examine the impact of childhood trauma on decent work. Childhood trauma was added as an exogenous variable in the Psychology of Working Theory (PWT) model and hypothesized to have direct and indirect effects on decent work. An online sample of 643 working adults completed PWT measures and a measure on childhood trauma. Additionally, participants completed a single Likert-type item measure assessing negative impact of COVID-19 on work so that model invariance could examined among two high and low impact groups. Group invariance was satisfied at the configural, metric, and scalar levels, and the …

Examining The Factor Structures Of The Erq-Ca, Rcads, And Rsca To Identify Unique Predictors Of Ptsd Symptom Clusters In Maltreated Youth, Amanda N. Howard

UNLV Theses, Dissertations, Professional Papers, and Capstones

Youth who have experienced maltreatment have a higher risk of developing posttraumatic disorder (PTSD), which is associated with poorer mental and behavioral health outcomes including emotion dysregulation, anxiety, depression, and lower resiliency. At present, the literature largely focuses on youth who have experienced general trauma or PTSD symptoms, while maltreated youth are vastly understudied. The present investigation was the first study to date to examine the factor structures of the Emotion Regulation Questionnaire for Children and Adolescents (ERQ-CA), the Revised Child Anxiety and Depression Scale (RCADS), and the Resiliency Scale for Children and Adolescents (RSCA) in a sample of maltreated …

Treatment Outcome From Cognitive Processing Therapy Examined Three Ways, Sophie Haven

Dissertations

Cognitive Processing Therapy (CPT), a Cognitive Behavioral Therapy for treating Post Traumatic Stress Disorder (PTSD), is an evidence-based treatment that has been demonstrated to be effective in treating PTSD. Nonetheless, CPT can have a high rate of treatment non-completion. Attrition from therapy has been operationally defined using multiple contrasting methods. Understanding attrition using a definition with the most clinical utility is essential to improving outcomes from efficacious treatments. Two clinically relevant definitions for attrition, session attendance and symptom improvement, are critical to understanding attrition. Combining information from both definitions, to create four separate groups, will provide more accurate information about …

Mind Over Matter: The Role Of Resilience, Crime Victimization, And Age At The Time Of Victimization On Psychological Health, Alana Compton

Undergraduate Theses and Capstone Projects

The purpose of this study was to examine the relationship between crime victimization, age at the time of victimization, psychological health, and resilience. Past research has shown that crime victimization has been linked to higher levels of depression and suicidal ideation, anxiety, posttraumatic stress disorder (PTSD), and eating disorders, and that those who experience a traumatic event as a child are influenced more negatively than those who experience trauma as an adult. Additionally, resilience has been shown to mediate the influence that trauma has on an individual. Undergraduate students, graduate students, and faculty and staff were surveyed to determine their …

The Mediation Of Mental Health Between Adverse Childhood Experiences And Risky Sexual Behavior, Kayla Marie Mandrigues, Julia Claire Dodd, Stacey Lynne Williams

Undergraduate Honors Theses

Risky sexual behaviors (RSB) have the potential to negatively impact individuals by increasing the risk of mental health issues, sexually transmitted infections (STIs), and unwanted pregnancies. Adverse childhood experiences (ACEs) and mental health disorders, such as anxiety, PTSD, and depression, have been known to increase RSB. The purpose of this study was to see if these mental health disorders mediate the relationship between ACEs and RSB. Participants (n = 342, mean age = 32) were recruited through social media to complete an online questionnaire. While history of ACEs significantly predicted engagement in RSB as well as all three of the …

Posttraumatic Stress, Depression, And Subjective Social Status: Potential Moderating Effects Of Optimism, Resilience, And Self-Efficacy, Caterina Obenauf

Masters Theses

The present study investigated the potential moderating effects of optimism, resilience, and self-efficacy on the relationships between subjective social status and both posttraumatic stress and depression symptom severity in a sample of undergraduate students (N = 382, M = 19.4, SD = 1.6, 81.5% White, 60.9% cisgender women) who reported experiencing one or more traumatic events. Many participants reported the highest education level attained by at least one parent being beyond a college degree (69%). Participants completed measures assessing trauma history, subjective social status, PTSD and depression symptoms, and potential psychological resources of optimism, resilience, and self-efficacy. In the …

Moral Injury To Inform Analysis Of Post-Traumatic Stress Disorder, Amanda Julia Manea

Senior Theses

Post-traumatic stress disorder (PTSD) is a mental health condition that almost one out of ten veterans struggle with. Although the National Center for PTSD has made extensive progress in characterizing and developing new treatments for PTSD, most veterans still experience symptoms of PTSD following treatment. Novel avenues of investigation, such as developing algorithms to review electronic health record (EHR) data and better understanding moral injury, are being pursued to address the gap that still exists when it comes to treating veterans. Moral injury is the individual evaluation of exposure to a potentially morally injurious event (PMIE) and can lead to …

The Chicken Or The Egg: A Proposed Longitudinal Study On Post-Traumatic Stress Disorder And Memory Impairment, Hominy Tara Mcmahon

Senior Projects Spring 2023

After experiencing trauma, some people go on to develop PTSD while others do not. Resilience and response to treatment also differ depending on the individual. To date, little research has been done to narrow down the reasons for these differences. Therefore, the main goal of this proposed 3-year longitudinal study of PTSD is to better understand the temporal relationship between the development of PTSD and structural changes in the hippocampus. Since PTSD is a costly disorder and disproportionately affects those serving in the military, this study may help determine better prevention tactics and treatment plans for those entering the military …

Non-Nightmare Recurring Dreams And Trauma, Asmai Fathelbab

Walden Dissertations and Doctoral Studies

This study examined the relationship between trauma and non-nightmare recurrent dreams (NNRD). Although there is extensive literature on the psychological consequences, diagnosis, and treatment of trauma, studies on the role of sleep processes have focused almost exclusively on nightmares. The potential relationship between NNRD and traumatic experiences has been overlooked by researchers. The purpose of this study was to assess if history of trauma and NNRD were correlated. More specifically, using Revonsuo’s threat simulation theory as a framework, the study evaluated if gender, quality of sleep, depression, anxiety, stress, and history trauma predicted NNRD. A cross-sectional correlational survey design was …

Effectiveness Of Writing Interventions For The Treatment Of Trauma: A Systematic Review, Melissa Maccarini

Theses and Dissertations

The effectiveness for writing interventions in the treatment of trauma has been a long-researched topic with research continuing to be conducted. This systematic review with narrative synthesis aimed to examine the effectiveness of writing interventions over the past two decades in reducing trauma or related symptoms in adults diagnosed with PTSD or having experienced a criterion-A event. Researchers searched the following databases: PsycINFO, Scopus, EBSCO, ProQuest (PTSDPubs), and PubMed. The last search yielded 100 manually full-text screened studies, with 18 articles included in the systematic review. The results point to some evidence for statistically significant decreases in trauma or related …

Distinguishing Different Types Of Childhood Maltreatment On Resting-State Connectivity Networks During Emerging Adulthood, Zoe Morris Feldman Brier

Graduate College Dissertations and Theses

Childhood maltreatment is a major public health concern and is associated with both psychological and brain changes in adulthood. Conceptualization of childhood maltreatment can be categorized along two axes, threat and deprivation, each of which can be associated with varying outcomes of psychopathology and brain changes. The brain is organized into broad connectivity networks, including the Salience Network (SN), the Default-Mode Network (DMN), and the Central Executive Network (CEN). Prior work has examined the relationship between these networks and psychopathology associated with childhood maltreatment, such as Post-Traumatic Stress Disorder (PTSD) and Major Depressive Disorder (MDD).

This study assessed the differences …

Neurobiology Of Ptsd In Adults And Children: The Impact Of Stress-Induced Brain Abnormalities Across The Lifespan, Catherine Clover

Undergraduate Honors Theses

In the scholarly community, there is disagreement about the effects of PTSD or chronic stress on the brain of adults and children. Though PTSD or chronic stress are known to negatively affect neurobiological structures, specifically due to prolonged glucocorticoid excess, volumetric discrepancies between traumatized and control groups are not unanimously confirmed. This review sought to address the common understandings in academia of the effects of PTSD on the brains of adults and children. Literature on this topic indicated that, in adults, the hippocampus, cingulate gyrus, and prefrontal cortex bilaterally appeared to decrease in gray matter volume and the corpus callosum …

Physiological Responses Regarding Stress And Trauma: The Freeze Response, Emma Arie Von Holten

UNF Graduate Theses and Dissertations

Fight-or-flight is a commonly known response to threatening situations, but the freeze response is another defensive mechanism that might arise in such situations. There is also evidence that exposure to trauma can impact physiological reactions when defensive mechanisms are not required, such as freezing in response to non-threatening situations. The current study aimed to replicate and expand upon a limited number of previous studies on the human freeze response by implementing measurements of postural sway, heart rate, and infrared thermography while valenced images were shown to participants. Ninety-two participants were recruited from the University of North Florida and participants were …
