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 …

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 …

First Responder Coping And Its Impact On Resilience, Ptsd Symptomology, And Hypervigilance, Bianca Bullock

Dissertations

The present study investigated coping strategies utilized by first responders and how those strategies relate to resilience, PTSD symptomology, and hypervigilance. The purpose of this study is to help provide more detailed information as to how first responders’ coping impacts their overall functioning. First responders (N = 181), including law enforcement officers, firefighters, paramedics, and emergency medical technicians, completed online surveys measuring whether engaged or disengaged coping strategies were used to manage stressful situations. Self-perceived resilience, PTSD symptoms, and hypervigilance were also measured. A one-way between-groups multivariate analysis of variance was performed to test the relationships between engaged versus disengaged …

More specifically, this literature review aims to explore if intimate partners and children of military service members are at risk for developing secondary traumatic stress. Secondly, this review aims to explore if there are specific risk factors associated with the development of secondary traumatic stress in intimate partners and children of service members. Finally, this review examines if there are other stressors and outcomes for intimate partners and children of service members. A systematic review of peer-reviewed research was explored to accomplish addressing the …

Exploring The Maladaptive Cognitions Of Moral Injury, Rachel L. Martin

Dissertations

Moral injury and Post-Traumatic Stress Disorder (PTSD) are two prominent mental health problems that affect military personnel. Moral injury results when the individual is exposed to a situation or event that violates their moral code; however, PTSD results when there is a substantial threat of harm. Moral injury is a relatively new construct within the literature with research starting in the late 2000s. Although distorted cognitions are core components of PTSD symptomatology, there has been no research of cognitions in moral injury. The current study sought to differentiate PTSD and moral injury using the specific maladaptive cognitions associated with trauma …

Mindfulness And Technology: Evaluating An Online Mindfulness Intervention For Symptoms Related To Sexual Assault, Erica Catherine Johnson

Dissertations

Sexual assault has been found to increase the risk of distressing psychological symptoms including PTSD, depression, somatization, drug and substance use, lower quality of life and experiential avoidance. As such, interventions for reducing the distress and negative impacts of sexual assault are of importance. Mindfulness is of particular interest as it addresses one of the prominent factors known to maintain psychological distress after trauma, experiential avoidance (Polusny et al., 2004; Merwin et al., 2009). Furthermore, an online mindfulness-based intervention can increase the accessibility and reduce the barriers to treatment. A within subjects repeated measures open clinical trial design was used …

Military Sexual Trauma In Veterans: Consequences, Treatment, And Therapeutic Implications, Chelsey Siville

Dissertations

Amongst Veterans served within the Veterans Affairs healthcare system, approximately 1 in 50 men and 1 in 3 women have experienced military sexual trauma (MST). While every individual is different, a common characteristic or identity amongst those who have served is that of a warrior – someone perceived as strong and ready to defend both their country and fellow soldier. Experiencing military sexual trauma can create a painful and discrepant identity as well as impact almost all domains of functioning. Unfortunately, trauma is an all too common occurrence in the lives of many service members and the multifinality of trauma …

Neurobiological Mechanisms Of Cognitive Processing Therapy For Post-Traumatic Stress Disorder: A Brain Network Approach, Tessa Vuper

Dissertations

Psychotherapy research is increasingly targeting both psychological and neurobiological mechanisms of therapeutic change. This trend is evident in and applicable to post-traumatic stress disorder (PTSD) treatment research given the high nonresponse rate of individuals with PTSD who undergo cognitive-behavioral therapy (CBT). A review of the literature investigating neurobiological mechanisms of CBT in PTSD reveals inconsistent results that fail to fully support dual process or learning models of CBT effects in the brain. However, network-based models of psychopathology provide a new framework from which to understand both mental disorder symptoms and therapeutic mechanisms. The current study investigated a) whether brain networks …

Ptsd Symptom Interaction Among Victims Of Interpersonal Violence: A Network Analysis, Robert Graziano

Dissertations

Along with numerous combinations of symptoms, posttraumatic stress disorder (PTSD) is linked to high dropout and non-response rates in treatment. Poor treatment response may be due to an inaccurate conceptualization of PTSD. One newer approach to the conceptualization of psychopathology is network theory. Network theory posits that symptoms both directly and indirectly reinforce each other, with connections between symptoms varying in strength. Previous studies of network theory and PTSD have found intrusive symptoms to be highly central, but have not included samples of individuals traumatized by interpersonal violence. Because trauma type has been shown to predict symptom presentations, this represents …

The Relationship Between Frequency Of Yoga And Meditation On Ptsd Symptoms In Individuals Who Have Experienced Intimate Partner Violence, Kimberly Polignani

Dissertations

Intimate partner violence (IPV) has become a growing phenomenon in the United States,

affecting nearly 13% of the population. The adverse mental health outcomes from people who experience IPV are prevalent and more than half have a diagnosis of posttraumatic stress disorder (PTSD). Therefore, therapeutic techniques for PTSD appear to be feasible for IPV survivors and their mental health issues. Complementary and alternative medicine has become a widely accepted approach for PTSD. Being two complementary and alternative medicine techniques, yoga and meditation are effective forms of therapy in many diagnoses, including PTSD. This study utilized a not-for-profit organization called the …

Examining The Gender- And Sexuality-Related Cognitive “Stuck Points” Of Men And Women With Experiences Of Adult Sexual Assault: Implications For Cognitive Processing Therapy, Marin Beagley

Dissertations

Cognitive Processing Therapy (CPT) is considered a gold-standard psychotherapy protocol for the treatment of posttraumatic stress symptoms secondary to a variety of traumatic events. Despite its demonstrated efficacy, there is research to suggest CPT may not be as effective in reducing PTSD symptoms for men with an adult sexual assault trauma as it is for their female counterparts. The purpose of the present study was to determine whether CPT treatment outcome discrepancies may be attributable to gender differences in posttraumatic cognitions, or “stuck points.” As the act of sexual victimization is incongruent with socially prescribed masculine gender norms, it was …

Understanding Comorbid Depression In The Context Of Ptsd Through Underlying Dimensions, Melissa Turkel

Dissertations

Depression co-occurs with Posttraumatic Stress Disorder at a high rate, resulting in numerous complications for pathology and treatment. More research is needed regarding variables that may explain this common comorbidity. One possible variable is that of underlying dimensions, latent factors that give rise to these manifestations of psychopathology. This study explored potential underlying mechanisms of comorbid PTSD and depression, including negative affect, rumination, emotion dysregulation, neuroticism, and behavioral inhibition. While previous studies have investigated these dimensions individually, there is a dearth of research that simultaneously investigates multiple dimensions or determines the relative contributions of underlying dimensions to psychopathology. Thus, the …

Clinician Bias In The Diagnosis Of Posttraumatic Stress Disorder: How Clinician Characteristics And Training May Relate To Diagnosis, Renee Boeck

Dissertations

As our understanding of PTSD has advanced, changing demographics in the United States over the past few decades have led to a growing awareness of the mental health needs of an increasingly diverse and multicultural population. Research on ethnoracial differences in PTSD has had mixed results and additional research exploring possible contributing factors is needed to better explain observed differences. This study explored the presence of and contributing factors to clinician bias in the diagnoses of PTSD based on race and context. It examined whether clinicians were more likely to diagnose PTSD in a Black or White man due to …

An Examination Of Subtypes Of Posttraumatic Stress Disorder Utilizing Latent Profile And Taxometric Analyses, Joseph Finn

Dissertations

Prior studies examining PTSD subtypes have yielded mixed results, likely stemming in part from the use of divergent samples and measurement techniques. This study aimed to expand upon these findings by utilizing a large nationally-representative sample in combination with sophisticated statistical analyses. Utilizing a sample of 2496 adults with a diagnosis of PTSD, latent profile analysis was used to determine the optimal number and composition of latent classes of individuals diagnosed with PTSD, and then taxometric analysis was utilized to determine whether these classes differed not only in degree, but in kind.

Finally, class relationships with a number of external …

The Associations Among Expressed Emotion, Relationship Satisfaction, Ptsd Symptoms, Alcohol Use, And Depression: A Longitudinal Investigation With A Military Sample, Laci Lee Zawilinski

Dissertations

PTSD in military personnel is highly prevalent and accompanied by elevated rates of additional issues such as depression, problematic alcohol use, and interpersonal relationship problems. Family members and spouses of military personnel have also been shown to be negatively impacted by PTSD symptoms. Previous research has indicated that family members and spouses’ expressed emotion regarding the PTSD patients’ symptoms negatively impacts treatment outcome in civilian populations. However, studies have yet to investigate the effect of expressed emotion on the course of PTSD symptoms and associated problems in military personnel. Therefore, the purpose of the present investigation was to examine the …

The Sexual Assault Severity Scale: A Comprehensive Measure Of Assault Severity, Karyn Crystal Swinson

Dissertations

Many studies in the sexual assault literature have found a significant relationship between sexual assault severity and psychological distress, specifically PTSD and suicidality. However, in the current literature, there is an inconsistent and incomplete definition of the construct of assault severity. The present study aims to create a comprehensive self-report questionnaire, called the Sexual Assault Severity Scale (SASS) that includes assault characteristics, such as victim-offender relationship, substance use, and peritraumatic responses, and cognitive variables, such as posttraumatic schema disruptions and coping self-efficacy in the conceptualization of assault severity. Two models evaluating the relationship between assault severity and post assault distress …

Trauma And Post-Traumatic Stress Disorder In Therapeutic Day School Students: Prevalence In This Population And Effective Treatment Programs, Monica Roberts

Dissertations

This survey-based, comparative study investigated the percentage of students at a suburban Chicago therapeutic day school who meet criteria for clinically significant levels of PTSD as compared to students in a general education setting. The directional hypothesis was that students placed at therapeutic day schools have a higher prevalence of PTSD than a general population of students. The method used was a survey assessment called the Child PTSD Symptom Scale (CPSS) given to 16 students at a suburban Chicago therapeutic day school. These CPSS scores were analyzed and statistically compared to CPSS scores of an already published study with students …

Neuropsychological, Psychological, And Injury Variables Associated With Post-Traumatic Stress Disorder In Individuals Who Suffered An Electrical Injury, Jana Wingo

Dissertations

Electrical injury (EI) represents a major form of trauma that can greatly impact the individual cognitively, physically, and emotionally. EI can lead to a variety of cognitive impairments affecting attention, processing speed, motor skills, and memory. Furthermore, EI can lead to a variety of physical impairments from burns to cardiac injury. In addition to other psychiatric disorders, individuals who suffer an EI can eventually develop Post-Traumatic Stress Disorder (PTSD).

This study examined a clinical sample of 143 individuals (86.0% male, 85.3% Caucasian, 44.1% diagnosed with PTSD) who have experienced an EI to determine the factors associated with the development of …

The Effect Of Writing As Exposure Therapy On Ptsd Symptoms, Daniel Scott Debrule

Dissertations

The majority of empirically supported treatments for Posttraumatic Stress Disorder involve some form of exposure, which desensitizes an individual to traumarelated information. Theoretical work has suggested that the mechanism of exposure may explain the tendency for writing to lessen symptoms, and empirical evidence of writing and PTSD symptoms suggests that modifying the writing paradigm may result in better symptom relief. The present investigation aimed to compare the efficacy of an exposurebased writing intervention to the standard writing paradigm. A total of 68 undergraduates that were screened for PTSD symptoms were randomly assigned to write about their most severe trauma for …
