Neural Correlates Of Rumination In Posttraumatic Stress Disorder Before And After Cognitive Processing Therapy, Katherine Ruth Buchholz

Dissertations

The utilization of functional magnetic resonance imaging (fMRI) techniques to examine biomarkers and neural activity patterns related to posttraumatic stress disorder (PTSD) has provided a way to investigate mechanisms that underlie the development, maintenance, and recovery from PTSD. Studying the neural correlates of individual differences related to transdiagnostic factors has the potential to provide clinically relevant information beyond that of diagnostic categories. Rumination is one such factor. Rumination, defined as repetitive, negative, self-focused thinking is considered to be a transdiagnostic factor that is associated with depression, anxiety, and PTSD. In individuals with PTSD, rumination serves as a cognitive avoidance factor …

Ptsd Symptom Severity And Neurocognitive Performance As A Function Of Combined Tms And Imaginal Exposure In Oif/Oef Combat Veterans With Treatment Resistant Ptsd, Katharine Seagly

Psychology Theses & Dissertations

Posttraumatic Stress Disorder (PTSD) is a commonly occurring mental health diagnosis, and is particularly prevalent in combat veterans. Although there has been some success treating PTSD with various forms of therapy, many cases remain refractory to the current standard of care. This pilot study combines transcranial magnetic stimulation (TMS) to the right dorsolateral prefrontal cortex (DLPFC) and the supplementary motor area (SMA) with a standardized exposure protocol for the treatment of chronic, treatment-resistant PTSD. The aims are to (1) determine if the treatment is safe and well tolerated, (2) determine if PTSD and concomitant depression and anxiety symptoms improve, and …

Treating Trauma: The Efficacy Of Emdr As A Treatment For Ptsd, Grace S. Crawford

Honors Projects

This literature review examines the efficacy of Eye Movement Desensitization and Reprocessing (EMDR) relative to other evidence-based treatments for Posttraumatic Stress Disorder (PTSD), such as Prolonged Exposure (PE) and Cognitive Processing Therapy (CPT). The paper explores the problem of PTSD; outlines the history, theory, and initial trials of EMDR; and examines five randomized controlled trials which compare EMDR to PE or CPT. Results suggest that neither treatment model produces significantly greater reductions in PTSD symptoms, though there is some evidence that EMDR may be better tolerated and produce desired results faster than other treatments.

The Impact Of Childhood Trauma As Moderated By Ptsd, Relationship With Caregiver, And Rumination, Aislyn M. Allen

Mechanisms Of Regulation: Profiling The Impact Of Emotion Regulation On Posttraumatic Stress Symptoms, Samantha Ann Chesney

Master's Theses (2009 -)

Trauma survivors are at a high risk for developing symptoms of posttraumatic stress (PTS) and often experience difficulties with emotion regulation. However, there is no clear understanding of how multiple strategies may be used to effectively regulate PTS. The current study evaluates participants' use of six different strategies and investigates whether a specific profile of emotion regulation (i.e., the individual's default pattern of regulation, determined by the frequency with which s/he uses different strategies from a regulation inventory) is related to PTS. Results of a hierarchical cluster analysis indicated that four profiles of emotion regulation were present in the current …

The Mechanisms Of Transmission: Examining The Effects Of Childhood Interpersonal Violence Across Generations, Amber Nemeth

Dissertations, Theses, and Capstone Projects

This study examined the direct relationship between maternal exposure to childhood interpersonal violence (sexual and/or physical abuse) and behavioral problems in her pre- to early-adolescent children. It also examined whether maternal aggression (psychological and physical aggression) and emotion dysregulation (lifetime PTSD diagnosis and alexithymia) exerted a significant indirect effect on this relationship. This study was a secondary analysis of data collected from a cross-sectional and cross-generational study designed to examine associations among maternal impairments (substance abuse, general psychopathology, neuropychological functioning), child-rearing deficits (parenting deficits, child neglect, child physical/ sexual abuse), and adverse child outcomes (self-regulation deficits, aggressive behavior, and substance …

Evaluation Of Behavioral Distress Tolerance Task Stability Across Settings, Cassie Overstreet

Theses and Dissertations

Distress tolerance (DT) is considered to be a trait-like factor encompassing an individual’s behavioral and/or perceived ability to withstand negative affective states. Behavioral measures of DT are being increasingly utilized, however, these tasks have been implemented in studies prior to thoroughly establishing the psychometric properties. The present study aimed to evaluate the reliability of two DT behavioral tasks (Breath-Holding Task [BHT], computer-based Paced Auditory Serial Addition Task [PASAT-C]) in different settings (laboratory, online) among a sample of college students. Participants completed the tasks during two sessions, approximately one week apart. 52 participants were in the laboratory condition, and 65 were …

Hiroshima And Mass Trauma Today: Treating Post-Traumatic Stress Disorder In Individuals And Communities, Ashley Martinez

International ResearchScape Journal

At 8:15 am on August 6^th, 1945, the world and the way in which we fight wars changed forever. Immediately following the drop of the Little Boy atomic bomb, the city of Hiroshima was decimated, leaving the surviving citizens to deal with poverty, starvation, loss of loved ones, and utter destruction of their lives. After the bombing, survivors were left with burns, radiation poisoning, and physical scars. Unknown to the survivors of the atomic bombings, or Hibakusha, were the ensuing psychological and emotional damages. In 2014, we know more about traumatic experiences than in 1945. Studies from …

The Effects Of Expert Testimony In Sexual Assault Trials, Lillybelle K. Deer

CMC Senior Theses

Recently, expert testimony in sexual assault trials shifted from an emphasis on Rape Trauma Syndrome (RTS) to Posttraumatic Stress Disorder (PTSD) and experts have tied these diagnoses either loosely or tightly to the victim’s condition following sexual assault. In the current study, 326 jury-eligible adults completed a survey on Amazon Mechanical Turk in which they read a synopsis of a sexual assault trial and an expert testimony with either RTS, PTSD or neither; along with either no, loose, or tight links made between the diagnosis and the victim’s condition. There was no main effect of diagnosis label but testimony linkage …

Post Traumatic Stress Disorder Symptoms And Intimate Relationships Of Female Survivors Of Sexual Assault: The Effects Of Treatment With Prolonged Exposure, Group, And Supportive Counseling Therapy, Gabrielle Rhoads

PCOM Psychology Dissertations

Theory and research suggest that post traumatic stress disorder (PTSD) symptoms may disrupt intimate relationships of survivors of trauma. Nevertheless, little empirical research has examined the role of PTSD and how it affects intimate relationships of survivors of sexual assault. This study utilized selected measures to examine the degree to which symptoms and treatment(s) for PTSD contribute to relationship satisfaction in female survivors of sexual assault. Overall, the severity of PTSD predicted relationship maladjustment at baseline, which is consistent with past research findings. More specifically, avoidance and arousal were found to be the most robust predictors of relationship maladjustment. This …

Scripps Senior Theses

Yoga postures (asana) and yoga breathing techniques (pranayama) could be an effective method of treating Post Traumatic Stress Disorder (PTSD). This study investigates the importance of the style of yoga treatment (pranayama, asana, or both) and the frequency with which these interventions are conducted (two or five times per week). The participants in this study will be military personnel with diagnosed PTSD who are currently receiving CBT and pharmaceutical treatment. All participants will have their PTSD symptoms assessed before the study begins, and then once a week each of the 12 weeks of the study. Structured interviews will be administered …

Combat-Related Posttraumatic Stress Disorder: Locus Of Control And Marital Satisfaction, Jesus Botello

Walden Dissertations and Doctoral Studies

Combat-related posttraumatic stress disorder (PTSD) is a psychological condition researchers have cited as a major cause of marital discord and divorce for veterans with PTSD. This study examined the psychological construct of locus of control among the wives of veterans diagnosed with combat-related PTSD and whether or not it was a predictor of marital satisfaction within this context. An extensive search of the current literature revealed no previous studies that had investigated this relationship. Utilizing the family systems theory to address this gap, this study sought to compare reported marital satisfaction in wives with an internal locus of control to …

Adhd Versus Ptsd In Preschool-Aged Children: Implications For Misdiagnosis, Klaudette D. Stewart

PCOM Psychology Dissertations

Attention Deficit Hyperactivity Disorder (ADHD) has been one of the most diagnosed disorders in children since it was included in the Diagnostic and Statistical Manual of Mental Disorders−III (DSM−III) in 1980. The number of children who have been diagnosed since that time has grown significantly, raising concerns about the overwhelming number of young children being diagnosed and prescribed medication. According to the literature, young children are diagnosed at a higher rate by pediatric primary care physicians (PCPs) than clinical child psychologists (CCPs) because they are taken to a PCP’s office by a parent, rather than referred from a school environment, …

Therapeutic Horseback Riding With Military Veterans: Perspectives Of Riders, Instructors, And Volunteers, Leslie Lafleur

Antioch University Dissertations & Theses

Statistics reveal that over 353,000 military members have been diagnosed with PTSD and/or TBI resulting from war-related activities. With the rising number of war stress injuries, there have not been enough psychotherapeutic services to meet the current demand for the care of returning veterans from Iraq and Afghanistan. Although some intervention strategies have been deemed successful, the current standards of care (e.g., exposure therapy, cognitive therapy) are limited by training inadequacies, accessibility, and outcomes (e.g., retention, early drop out, resistance, non-responsiveness). Furthermore, it is unclear whether these treatments are efficacious in addressing the unique symptom presentations of this population. The …

Ptsd Symptomology And Relationship Dysfunction: Is Emotional Reactivity The Culprit?, Kristin Lytle

USC Aiken Psychology Theses

Emotional numbing, a symptom of PTSD, has been found to be strongly associated with relationship dysfunction (Erbes et al., 2011; Monson et al., 2012; Riggs et al., 1998; Solomon et al., 2008). It is thought that emotional numbing can negatively impact relationships, yet there is limited understanding of the mechanisms of emotional numbing. Information processing theory developed by Litz and Gray (2001) suggests that emotional numbing is not a generalized response to all emotions and is actually specific to positive emotions. They believe that people with PTSD actually experience heightened negative emotions which then lead to emotional numbing to positive …

Posttraumatic Outcome Of Intimate Partner Violence: An Examination Of Risk Factors, Joye L. Henrie

Graduate Theses and Dissertations

Not all individuals who experience intimate partner violence (IPV) victimization experience clinically significant negative outcomes following IPV exposure. For those that do experience negative outcomes, researchers need to identify the mechanisms through which they develop and the manner in which negative symptoms may develop differentially across individuals. This paper provides a review of risk factors associated with negative outcomes following IPV victimization. Accumulated lifetime maltreatment experiences and maladaptive cognitions are both proffered as potential risk factors for Post-traumatic Stress Disorder (PTSD) outcomes following IPV exposure. A community sample (N = 244) of adult females was recruited to assist in elucidating …

Exploring The Inner Experience Of Veterans With Posttraumatic Stress Disorder, Stacy Reger

UNLV Theses, Dissertations, Professional Papers, and Capstones

Military veterans have returned from combat changed by exposure to trauma for as long as history has been recorded. The field of psychology contains a vast literature describing and attempting to understand Posttraumatic Stress Disorder (PTSD) and its detrimental effects on the lives of individuals with the disorder. Despite the volume of study dedicated to PTSD in the literature, in-depth accounts of the lived experience of individuals with PTSD are rare. The current study utilized Descriptive Experience Sampling (DES), a method based on apprehending high-fidelity accounts of momentary inner experience, to explore the inner experience of eight Operation Iraqi Freedom …

Factor Structure Of Ptsd, And Relation With Gender In Trauma Survivors From India, Ruby Charak, Cherie Armour, Ask Elklit, Disket Angmo, Jon D. Elhai, Hans M. Koot

Psychological Science Faculty Publications

Background: The factor structure of posttraumatic stress disorder (PTSD) has been extensively studied in Western countries. Some studies have assessed its factor structure in Asia (China, Sri Lanka, and Malaysia), but few have directly assessed the factor structure of PTSD in an Indian adult sample. Furthermore, in a largely patriarchal society in India with strong gender roles, it becomes imperative to assess the association between the factors of PTSD and gender.

Objective: The purpose of the present study was to assess the factor structure of PTSD in an Indian sample of trauma survivors based on prevailing models of PTSD defined …

Hardiness, Social Support, Parental Stress, And Posttraumatic Stress Symptoms In Recent Service Members, Victoria Jane Tomassetti-Long

Dissertations

Previous research has demonstrated a link between PTSD symptomatology (PTSS) and parenting stress in veterans. As the literature on veterans of the wars in Iraq and Afghanistan is increasing, there has been a call to identify variables which may contribute to positive outcomes in these service members (e.g., Cornum, Matthews, & Seligman, 2011). Hardiness is a personality variable that describes an individual’s sense of commitment, control, and challenge in light of life stress and has been identified as a protective factor against the development of psychological symptoms and parenting stress in combat veterans. Social support also seems to have benefits …

Identifying Maltreated Youths At Heightened Risk For Posttraumatic Symptoms, Emma H. Ross

UNLV Theses, Dissertations, Professional Papers, and Capstones

Childhood maltreatment is associated with increased risk for lifetime and current PTSD (Davis & Siegel, 2000; Widom, 1999). This study examined a model of PTSD in which dissociation, depression, and posttraumatic cognitions related to heightened PTSD symptoms for maltreated youths. This study then evaluated the model's fit across variations in intelligence, gender, age, ethnicity, and maltreatment type. Participants (n=360) included youths from Department of Family Services-related sites in Las Vegas. The first hypothesis was that the model would display goodness-of-fit across various indices. The second hypothesis was that the model would better fit youths with below average intelligence (FSIQ = …

Interleukin-6 And Soluble Interleukin-6 Receptor Levels In Posttraumatic Stress Disorder : Associations With Lifetime Diagnostic Status And Psychological Context., Tamara L. Newton, Rafael Fernandez-Botran, James J. Miller, Vicki Ellison Burns

Faculty and Staff Scholarship

This study correlated lifetime PTSD diagnostic status with interleukin-6 (IL-6) and soluble IL-6 receptor (sIL-6R) levels, and tested whether these correlations are sensitive to psychological context. Midlife women attended two research visits where blood was drawn (beginning of visits) and saliva and oral mucosal transudate were collected (beginning and end of visits) to measure IL-6 and sIL-6R. Women were classified as PTSD−/− (past and current symptoms below subsyndromal levels), PTSD+/− (past symptoms at or above subsyndromal levels), or PTSD +/+ (past and current symptoms at or above subsyndromal levels). PTSD+/+ women, compared to the other women, showed more negative emotion …

Psychology Faculty Publications

Background: As many as 70% of veterans with chronic pain treated within the US Veterans Administration (VA) system may have posttraumatic stress disorder (PTSD), and conversely, up to 80% of those with PTSD may have pain. We describe pain experienced by US service members and veterans with symptoms of PTSD, and report on the effect of Accelerated Resolution Therapy (ART), a new, brief exposure-based therapy, on acute pain reduction secondary to treatment of symptoms of PTSD.

Methods: A randomized controlled trial of ART versus an attention control (AC) regimen was conducted among 45 US service members/veterans with symptoms of combat-related …

Exposure Dose, Trauma Type, And Attrition In Ptsd Efficacy Studies, David R. Phillips

Master's Theses and Doctoral Dissertations

Both treatment outcome studies and meta-analyses document the efficacy of multiple cognitivebehavioral methods for treating PTSD. These reports have demonstrated that exposure-based therapies such as Prolonged Exposure (PE), Cognitive Processing Therapy (CPT), and Eye Movement Desensitization and Reprocessing (EMDR) consistently match or exceed their nonexposure counterparts in regard to efficacy. Yet the issue of attrition remains a significant concern for exposure-based therapies specifically. The present study compared the relationship between exposure therapies, exposure dose, trauma type, and attrition rates. A comprehensive literature search located 32 studies that met search criteria (i.e., random assignment to groups, use of a control group, …

How Coping, Ptsd And Treatment Preferences Interact?, Martha Mae Golubski

ETD Archive

Posttraumatic Stress Disorder (PTSD) is a mental disorder characterized by symptoms of intrusive recollection, avoidance or numbing, and hyper arousal following being exposed to a traumatic event involving threatened or actual death or serious injury (4th ed., text rev, DSM-IV-TR American Psychiatric Association, 2000). Those with PTSD, employ a variety of coping strategies to deal with the symptoms following their trauma exposure. Across studies, it has been found that coping styles which are active have a positive effect on both physical and psychological health (Gil & Caspi, 2005 Lazarus & Moskowits, 2004 Olff, Langeland, & Gersons, 2005). However, avoidance coping …

Examining The Role Of Unit Cohesion As A Moderator Of The Relationship Between Warfare Exposure And Ptsd, Shaina Gulin

Theses and Dissertations

The purpose of the current study was to examine the effects of warfare exposure and unit cohesion on posttraumatic stress disorder (PTSD) symptomatology among male and female National Guard and Reserve service members deployed to Iraq or Afghanistan. National Guard and Reserve soldiers and female service members have been shown to be at greatest risk of psychological distress, and thus identification of resiliency factors among this population is worthy of further study. An emerging body of research has identified unit cohesion as a potentially modifiable protective factor against the deleterious effects of warfare exposure; however, such research is in its …
