How Art Therapy And Emdr Help Asylum Seekers And Refugees Move Towards Healing Trauma: A Literature Review, Anna Mogilevsky May 2025

How Art Therapy And Emdr Help Asylum Seekers And Refugees Move Towards Healing Trauma: A Literature Review, Anna Mogilevsky

Expressive Therapies Capstone Theses

In the past ten years, there has been a significant rise in the number of asylum seekers and refugee populations worldwide (UNHCR, 2022). Displaced individuals are extremely vulnerable to mental illness because of the compounded trauma experienced in their countries of origin with the stress of immigration, asylum seeking, culture shock, and language barriers. PTSD is affecting 500 million individuals globally, and refugees are especially susceptible to having these symptoms (Farrell, 2020). Art therapy and EMDR are identified as the most promising modalities for treating such trauma.

This literature review examines the various ways EMDR and art therapy have been …


Pathways From Childhood Sexual Abuse To Sexual Risk Behaviour In Msm: A Mixed Methods Study, Daniel Provenzano Jan 2024

Pathways From Childhood Sexual Abuse To Sexual Risk Behaviour In Msm: A Mixed Methods Study, Daniel Provenzano

Electronic Theses and Dissertations

Men who have sex with men (MSM) are disproportionately affected by childhood sexual abuse (CSA) compared to heterosexual men. CSA has been associated with a wide range of adverse outcomes later in life, including engagement in sexual risk behaviours (e.g., condomless anal intercourse), that place MSM at greater risk for HIV acquisition and transmission. Although the links between CSA and sexual risk are well-established among MSM, little research has investigated psychosocial factors that may mediate this relationship. Using a mixed-method approach, this study (a) explored psychosocial factors as pathways linking a composite of complex CSA experiences (i.e., CSA complexities) with …

Trauma related symptoms and posttraumatic stress disorder (PTSD) have long been recognized for their connection to military and veteran populations and has become a significant barrier to the provision of mental healthcare. This original contribution to practice explores the significance of Canine Assisted Therapy as a novel approach to treating trauma in veteran and military populations. An extensive literature review examines the current research and discussion on trauma-informed care. It begins with a discussion on evidence-based practices for the treatment of PTSD, including Cognitive Processing Therapy, Prolonged Exposure, and Eye Movement Desensitization and Reprocessing. This is followed by a comprehensive …


The Examination Of Suicidal Ideation And Ptsd Among First Responders, Amanda Catalan Jan 2024

The Examination Of Suicidal Ideation And Ptsd Among First Responders, Amanda Catalan

Psychology Doctoral Specialization Projects

First responders are vital to our safety and protection, but this does not come without a price. First responders are often exposed to life threatening situations that put them at risk, and are exposed to those in critical condition, and unfortuantely, those who have died. This makes first responders more at risk to develop mental health conditions, particulalrly Posttraumatic Stress Disorder. (PTSD). First Responders were found to be more likely compared to civilians to develop PTSD. They were also more likely to experience suicidal ideation. First responders who met criteria for a PTSD diagnosis were also more likely to have …


Ptsd, Chaos, And Subjective Executive Dysfunction, And Its Impact On Qol, Emmy Y. Velazquez Santiago Jan 2024

Ptsd, Chaos, And Subjective Executive Dysfunction, And Its Impact On Qol, Emmy Y. Velazquez Santiago

PCOM Psychology Dissertations

Research with veterans suggests executive dysfunction associated with PTSD often results in problems with quality of life. Objective impairments in executive functions do not significantly correlate with subjective reports; despite this discrepancy, the perception of dysfunction impacts quality of life. Research indicates that perception of chaos/unpredictability can undermine the ability to perform executive functions. This study explored how the perception of chaos impacts the relationship between PTSD and subjective executive dysfunction and quality of life among veterans. A Pearson product-moment correlation was used to determine whether a relationship exists between PTSD symptomatology and subjective executive dysfunction and between subjective executive …


Survivor Experiences Of Male Childhood Sexual Abuse: A Literature Review, Elizabeth Burch B.S., Joseph T. Kenneally Psy.D., Stephanie Zepeda Phd Oct 2023

Survivor Experiences Of Male Childhood Sexual Abuse: A Literature Review, Elizabeth Burch B.S., Joseph T. Kenneally Psy.D., Stephanie Zepeda Phd

Psychology from the Margins

The World Health Organization (WHO) recognizes childhood sexual abuse (CSA) as a global health issue. CSA is a human violation that affects both female and male children and has a stronger detrimental impact on mental health than other traumatic childhood experiences. Despite a growing awareness of male survivors of CSA, male survivors are a marginalized group as most CSA research focuses on females. In addition, masculine norms can keep male adults from disclosing further, which can delay support and increase mental health issues. This meta- analysis reviews the current literature on this group of marginalized people and concludes with a …


Understanding The Experiences And Associated Symptomology Of Disclosers And Non-Disclosers Of Sexual Victimization, Kaitlin Carson Sep 2023

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 …


Trauma Mediating The Severity Of Depressive Symptoms In Veterans With Ptsd, Meghan Curtin Sep 2023

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 Sep 2023

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 …


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 Aug 2023

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 May 2023

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 …


Moral Injury To Inform Analysis Of Post-Traumatic Stress Disorder, Amanda Julia Manea Apr 2023

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 …


Trauma Exposure And Transdiagnostic Distress: Examining Shared And Ptsd-Specific Associations, Michael L. Crowe, Sage E. Hawn, Erika J. Wolf, Terence M. Keane, Brian P. Marx Jan 2023

Trauma Exposure And Transdiagnostic Distress: Examining Shared And Ptsd-Specific Associations, Michael L. Crowe, Sage E. Hawn, Erika J. Wolf, Terence M. Keane, Brian P. Marx

Psychology Faculty Publications

Dimensional models of psychopathology suggest that the causes and consequences of psychopathology are attributable to a combination of syndrome specific and transdiagnostic features. There is considerable evidence that trauma exposure confers risk for a wide range of psychiatric conditions, yet no previous work has specifically examined the higher-order effects of trauma exposure within a structural model. We examined transdiagnostic and PTSD-specific associations with multiple forms of trauma exposure within a nation-wide sample (N = 1,649; 50% female) of military Veterans over-selected for posttraumatic stress disorder (PTSD). A higher-order Distress variable was estimated using PTSD, major depressive disorder (MDD), and generalized …


Ptsd And Alcohol Use Disorders Predict The Pace Of Cellular Aging, Sage E. Hawn, Xiang Zhao, Mark W. Miller, Sara Wallander, Christine Govan, Anjanette Stone, Steven A. Schichman, Mark W. Logue, Erika J. Wolf Jan 2023

Ptsd And Alcohol Use Disorders Predict The Pace Of Cellular Aging, Sage E. Hawn, Xiang Zhao, Mark W. Miller, Sara Wallander, Christine Govan, Anjanette Stone, Steven A. Schichman, Mark W. Logue, Erika J. Wolf

Psychology Faculty Publications

Advanced epigenetic age is associated with psychopathology and may help to explain the link between psychopathology and physical health morbidity and mortality. Using a longitudinal sample of 171 trauma-exposed Veterans, we modeled the rate of change in epigenetic age across two time points (averaging 5.58 years apart) using two epigenetic age algorithms (GrimAge and Horvath) and tested associations with posttraumatic stress disorder (PTSD), alcohol use disorder (AUD), and depression. Results showed that PTSD (β = .199) and AUD (β = .186) were associated with a quickened pace of epigenetic aging over time (ps < .021). Results replicate and extend prior work and offer foundational support for identifying interventions that slow the pace of biological aging among those with psychopathology.


Distinguishing Different Types Of Childhood Maltreatment On Resting-State Connectivity Networks During Emerging Adulthood, Zoe Morris Feldman Brier Jan 2023

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 …

First Responder Coping And Its Impact On Resilience, Ptsd Symptomology, And Hypervigilance, Bianca Bullock Sep 2022

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 …


The Necessity Of Trauma-Focused Curricula In Mental Health Graduate Programs: Advocating For Comprehensive Trauma Etiology And Treatment Education With Proposed Course Outline, Aaron S. Gillespie May 2022

The Necessity Of Trauma-Focused Curricula In Mental Health Graduate Programs: Advocating For Comprehensive Trauma Etiology And Treatment Education With Proposed Course Outline, Aaron S. Gillespie

Graduate School of Professional Psychology: Doctoral Papers and Masters Projects

During the past four decades, it has become increasingly clear how prevalent trauma, polytrauma and co-morbid trauma-related disorders are within our shared, global communities. A growing body of research continues to uncover the mind-boggling impact these overwhelming experiences have on individuals, their families, and the communities that support them, including mental health professionals. It behooves us as allied mental healthcare providers to learn what trauma is, how it may affect the individual across the lifespan, as well as how to effectively identify and treat the trauma-related symptoms our clients present with. However, despite a proliferation of research demonstrating the growing …


Is Ego Strength A Trait That Contributes To Trauma Resilience?, Matt Hiltebrand, Feb 2022

Is Ego Strength A Trait That Contributes To Trauma Resilience?, Matt Hiltebrand,

Doctor of Psychology (PsyD)

Given the ubiquitous experience of trauma among first responders, there is a critical need to understand the traits that contribute to resilience in experiencing traumatic events. Strength of identity is associated with resilience in several meaningful life events including negative peer review, adjustment to significant change, and recovering from depression or anxiety (Kim & Choi, 2013). There is a scarcity of research that has examined ego strength as a trait that contributes to trauma resilience. The aim of this study was to explore the relationship between ego strength and the experience of trauma among veteran first responders (including, paramedics, firefighters, …


A Model Of Childhood Maltreatment, Ptsd Symptoms, Reinforcement Sensitivity, And Alcohol Outcomes In Young Adults, Logan E. Welker Jan 2022

A Model Of Childhood Maltreatment, Ptsd Symptoms, Reinforcement Sensitivity, And Alcohol Outcomes In Young Adults, Logan E. Welker

Dissertations and Theses

Alcohol use poses a significant public health concern, particularly among young adults, 35% of whom report binge drinking (SAMHSA, 2019). Childhood maltreatment is reported by over 50% of young adults (Maples et al., 2014) which places individuals at a greater risk of problematic drinking (Goldstein et al., 2010). Developmental traumatology theory posits that 1) maltreatment-related psychobiological changes are responsible for the increased risk of dysfunctional alcohol use in maltreated individuals and 2) PTSD may be a good indicator of this psychobiological change (De Bellis, 2002). PTSD symptoms have mediated the relationship between childhood maltreatment and alcohol outcomes in previous studies …


Efficacy And Possible Mechanisms Of Change In Written Exposure Therapy In Undergraduates With Ptss: A Randomized Trial Of Wet Compared To Trauma-Focused Expressive Writing, Robyn Alyssa Ellis Jan 2022

Efficacy And Possible Mechanisms Of Change In Written Exposure Therapy In Undergraduates With Ptss: A Randomized Trial Of Wet Compared To Trauma-Focused Expressive Writing, Robyn Alyssa Ellis

Graduate Research Theses & Dissertations

Trauma exposure is common, with a 90% lifetime endorsement rate in adults in the United States and a majority of first year students reporting exposure to trauma prior to college. A minority of individuals go on to develop PTSD, with higher rates on college campuses (9-12.4%) than lifetime estimates (7%). Existing evidence-based practices for PTSD have demonstrated efficacy in reducing PTSD symptoms (PTSS), but critiques of evidence-based psychotherapies (EBPs) for PTSD include high levels of drop-out and barriers to access. Written exposure therapy (WET) is a brief promising intervention for PTSS with a growing literature of evidence suggesting efficacy with …


The Experience Of Providing Direct Care To Children Victims Of Boko Haram Insurgencies In Nigeria, Felicia Etuke Jan 2022

The Experience Of Providing Direct Care To Children Victims Of Boko Haram Insurgencies In Nigeria, Felicia Etuke

Walden Dissertations and Doctoral Studies

The insurgency of terrorism leaves lasting economic, social, academics, spiritual, religious, and psychological effects, but often children’s psychological welfare is neglected in the aftermath of terrorist attacks. Boko Haram’s presence in Nigeria has left many children orphaned, displaced, and impoverished. Thus, there is a need to highlight the importance of the role that care providers play in securing the psychological health of the child victims of Boko Haram insurgency. This qualitative, phenomenological study explored the experiences of care providers to the child victims of Boko Haram insurgency in Nigeria. Compassion fatigue theory was used as a theoretical framework for the …


Tripping Over Trauma: A Proposal Of Psilocybin-Assisted Therapy For Comorbid Post-Traumatic Stress Disorder And Depression, Liam Paul Gomez Jan 2022

Tripping Over Trauma: A Proposal Of Psilocybin-Assisted Therapy For Comorbid Post-Traumatic Stress Disorder And Depression, Liam Paul Gomez

Senior Projects Spring 2022

Post-traumatic Stress Disorder (PTSD) is a widespread, often debilitating affliction that is only partially attenuated by current first-line treatment despite its heightened prominence in the sociopolitical arena. Since individuals with PTSD also experience high rates of depression comorbidity and resultant suicidality, it is essential that treatment is more holistically effective. A possible novel intervention, psilocybin-assisted therapy, has shown promising results for the improvement of depression, addiction, and other disorders; prospectively, when administered with non-directive therapy, it could prove to be an efficacious intervention for PTSD with comorbid depression. In the proposed study, there will be two participant groupings: the control …


Can Brazilian Jiu Jitsu Be A Viable Treatment Option For Law Enforcement Officers With Ptsd?, Megan Rinderer Jan 2022

Can Brazilian Jiu Jitsu Be A Viable Treatment Option For Law Enforcement Officers With Ptsd?, Megan Rinderer

Graduate School of Professional Psychology: Doctoral Papers and Masters Projects

Law enforcement officers (LEO) are more likely to experience symptoms of PTSD when compared to the general population yet are less likely to seek mental health treatment (Jetelina et al., 2020). Given that LEO face unique occupational stressors and repeated exposure to traumatic events, treatment for PTSD among law enforcement populations poses unique challenges for clinicians. The combination of these variables precludes officers from seeking and receiving mental health services. Research regarding the efficacy of Brazilian Jiu Jitsu (BJJ) as a psychotherapeutic intervention is limited. To date, no studies have examined the use of BJJ to mitigate symptoms of PTSD …


Racial/Ethnic Disparities In Mental Health Diagnosis Of Maltreated Youth, Shadie Burke Dec 2021

Racial/Ethnic Disparities In Mental Health Diagnosis Of Maltreated Youth, Shadie Burke

UNLV Theses, Dissertations, Professional Papers, and Capstones

Racial/ethnic marginalized youth are more likely to receive a misdiagnosis of a mental health disorder than their White peers. Misdiagnosis contributes to existing disparities for racial/ethnic marginalized groups by leading to longer durations of untreated and worsening mental health symptoms. For maltreated youth, receiving a misdiagnosis can lead to a failure to connect with appropriate mental health services, medication regimens, therapeutic foster homes, and academic and developmental resources. To date, very few empirical studies have identified disparities in mental health diagnosis among racial/ethnic marginalized maltreated youth. The present study examined two key research questions: (1) what racial/ethnic disparities in diagnoses …

Relations Between Ptsd Symptoms And Pain Interference Among Older Adults, Laura E. Travers Jun 2021

Relations Between Ptsd Symptoms And Pain Interference Among Older Adults, Laura E. Travers

Theses and Dissertations

Both the older adult population and the frequency of natural disasters (e.g., hurricanes) increase in the U.S. each year. Consequently, understanding the health experiences that affect older adults specifically following a natural disaster is important for providing effective healthcare and promoting health expectancy. For example, the extent to which PTSD symptoms following a natural disaster contribute to pain severity (beyond the contributions of other psychosocial experiences such as depression) among older adults is not yet clear, and whether this contribution differs by gender or age has yet to be established. The aims of this study were (1) to determine whether …


Effects Of Sleep On Intrusive Symptoms And Emotional Reactivity In A Laboratory-Based Film Analog Study, Anna Marie Thi Thanh Nguyen May 2021

Effects Of Sleep On Intrusive Symptoms And Emotional Reactivity In A Laboratory-Based Film Analog Study, Anna Marie Thi Thanh Nguyen

Graduate Theses and Dissertations

Posttraumatic stress disorder (PTSD) is characterized by four symptom clusters. Recently, research highlights the need to focus on the impact of intrusive symptoms as a possible risk factor for the development and maintenance of PTSD. Cognitive and sleep models contribute to further understanding of intrusive symptoms. Recent work also highlights disgust as an emotion closely associated with the emergence of posttraumatic stress symptomology following traumatic events. This study used a film eliciting disgust in order to examine the effects of sleep on the intensity of intrusion symptoms and emotion reactivity. The sample consisted of 49 college students randomly assigned to …


Neural Correlates Underlying The Interactions Between Anxiety And Cannabis Use In Predicting Motor Response Inhibition, Richard Ward May 2021

Neural Correlates Underlying The Interactions Between Anxiety And Cannabis Use In Predicting Motor Response Inhibition, Richard Ward

Theses and Dissertations

The ability to effectively withhold an inappropriate response is a critical feature of cognitive control. Prior research indicates alterations in neural processes required for motor response inhibition in anxious individuals, including those with posttraumatic stress disorder (PTSD), and those who engage in regular cannabis use. However, thus far most research has examined how anxiety-related symptoms and cannabis use influence response inhibition in isolation of one another. The current study examined the interactions between anxious symptomology and recent cannabis use in a sample that recently experienced a traumatic event using functional magnetic resonance imaging (fMRI) during the completion of a Stop-Signal …
