The Association Between Stigma And Violence Among Individuals With Schizophrenia, Christopher Law

Loma Linda University Electronic Theses, Dissertations & Projects

Schizophrenia is a psychotic disorder characterized by positive, negative, and cognitive symptoms. Individuals with schizophrenia (IWS) are often stigmatized and portrayed as dangerous. While the majority of IWS are not dangerous or violent, this image of the dangerous IWS is still pervasive across different cultures. Apart from the individuals who have exhibited antisocial traits prior to the onset of their psychosis, medication can significantly reduce the risk for aggressive and violent behaviors among IWS. However, as the literature reveals, medication noncompliance has become an significant issue among IWS. Studies show that stigmatization of schizophrenia has significantly contributed to individuals not …

Inflammation In Older Adults: Stress, Depression, And Aces, Kerianne Kramer

Loma Linda University Electronic Theses, Dissertations & Projects

Studies conducted on Adverse Childhood Experiences (ACEs) have shown that childhood adversity is relatively common, likely to co-occur, and have dose-dependent relationships with mental and physical health in adulthood. People with a history of ACEs are likely to experience dysregulation of the hypothalamic-pituitary-adrenal (HPA) axis, leading to increased inflammation production, greater stress reactivity, and decreased serotonin production. This longitudinal study explored the role depression and perceived stress have in the relationship between ACEs and inflammation while controlling for demographic characteristics (e.g., age, gender, ethnicity, education, difficulty meeting expenses). The study sample included 288 (61% female, 66% white, Mage = 68, …

Gender Differences In The Clinical Presentation Of Borderline Personality Disorder: A Review, Kimberly Glover

Dissertations

Borderline personality disorder is diagnosed in women three times more than men and represents a significant gender disparity amid considerable stigmatization compared to other psychological disorders. Empirical studies have investigated the gender prevalence for borderline personality disorder and further determined that findings may be due to differences in how borderline personality disorder clinically manifests in men and women. Common areas of investigation have included developmental features, diagnostic symptomology, psychiatric comorbidities, and the level of functional impairment for individuals with borderline personality disorder. An analysis of existing data was indicative of shortcomings in methods that include small samples of men, a …

A systematic review of peer-reviewed research was explored to accomplish addressing the …

Childhood Adhd, Impulsivity, And Alcohol-Related Impairment Among Diverse College Students, Mariely Hernandez

Dissertations, Theses, and Capstone Projects

Aims: We examined (1) if students with high childhood ADHD symptoms, and at high risk for alcohol use disorder (AUD) reported greater alcohol-related impairment (ARI) than their low childhood ADHD peers who had comparable rates of alcohol use; and (2) whether alcohol-related problems were more severe for those with high childhood ADHD and high AUD risk when their trait impulsivity was high.

Method: 18-to 25-year-old (N=81), racially/ethnically diverse, college students completed a two-part study. An online survey assessed childhood ADHD symptoms (Wender Utah Rating Scale) and past-year alcohol use (Alcohol Use Disorders Identification Test). Laboratory assessment comprised neuropsychological and self-report …

The Influence Of Evidence-Based Sex Discrimination Policies On Women’S Perceptions Of Organizational Climate, Sexism, And Identity Safety, Maya A. Godbole

Dissertations, Theses, and Capstone Projects

Sexism has proven to be a stubborn barrier to women’s participation and advancement in workplaces and academic institutions (Rosette, Akinola, & Ma, 2017). Importantly, sexism in organizational settings has endured despite the implementation of federal, state, and organizational policies that prohibit discriminatory behavior. One reason for this may be that because organizational policies are typically written for the purpose of complying to federal and state laws, they do little to foster psychological safety among employees and address the “chilly” organizational climates that enable sexism. To that end, the current research aimed to (a) develop novel, evidence-based sex discrimination policies and …

Medication Assisted Treatment: Examining Enrollment And Demographic Factors Of Treatment, Antwana Letoya Drayton

Theses and Dissertations

Opioid Use Disorder (OUD) has been a long-standing epidemic concern related to the continuous growth of variations of the substance and its’ potency. Due to the versatility of the substance to be both an illicit drug and also a prescription medication, the interest in controlling and monitoring its’ use creates a greater public health concern. Treatment overtime has been revitalized to directly address the social, biological, and physiological difficulties of patients with OUDs. Medication Assisted Treatment (MAT) has been explored and has become one of the most widely used plans for treatment of Substance Use Disorders (SUDs) related to pain …

Estimating The Associations Between Big Five Personality Traits, Testosterone, And Cortisol, Zachary Sundin, Lester Sim

Research Collection School of Social Sciences

Objective: Hormones are often conceptualized as biological markers of individual differences and have been associated with a variety of behavioral indicators and characteristics, such as mating behavior or acquiring and maintaining dominance. However, before researchers create strong theoretical models for how hormones modulate individual and social behavior, information on how hormones are associated with dominant models of personality is needed. Although there have been some studies attempting to quantify the associations between personality traits, testosterone, and cortisol, there are many inconsistencies across these studies. Methods: In this registered report, we examined associations between testosterone, cortisol, and Big Five personality traits. …

Desire, Culture, And The Body, Zoey Lavallee

Dissertations, Theses, and Capstone Projects

What is the nature of desire? In this dissertation I develop a theory of desire according to which desires are essentially enculturated states that play the role of presenting favorable outcomes that act as inputs to intention formation, and thereby intentional action. This analysis of desire debunks a common assumption shared by prominent accounts of desire in philosophy of mind, what can be called the dualist assumption: that bodily desires such as urges and appetites differ in kind from conceptual desires that are typically described as higher cognitive attitudes. I argue that the desires traditionally understood as bodily or appetitive …

Adaptability As A Moderator On The Impact Of Childhood Sexual Abuse And The Development Of Posttraumatic Stress Symptoms, Courtney Marie Kalmanson

Theses and Dissertations

Globally, it is estimated that 11.8% children experience Childhood Sexual Abuse (CSA) prior to the age of 18 (Stoltenborgh et al., 2011). However, the current prevalence rate of CSA is far underestimated due to the fear, shame, and denial that the victim experiences. Similarly, many survivors of CSA experience post-traumatic stress symptoms (PTSS) following the experience of CSA, which may develop into post-traumatic stress disorder (PTSD) over time. Furthermore, some children may adjust well despite the traumatic experience, suggesting resiliency. Much of the research on CSA focuses on the link between CSA and development of psychopathology, including but not limited …

Acute White Matter Integrity Post-Trauma And Prospective Posttraumatic Stress Disorder Symptoms, Carissa N. Weis, Ashley A. Huggins, Tara A. Miskovich, Jacklynn M. Fitzgerald, Kenneth P. Bennett, Jessica L. Krukowski, E. Kate Webb, Terri A Deroon-Cassini, Christine L. Larson

Psychology Faculty Research and Publications

Background: Little is known about what distinguishes those who are resilient after trauma from those at risk for developing posttraumatic stress disorder (PTSD). Previous work indicates white matter integrity may be a useful biomarker in predicting PTSD. Research has shown changes in the integrity of three white matter tracts—the cingulum bundle, corpus callosum (CC), and uncinate fasciculus (UNC)—in the aftermath of trauma relate to PTSD symptoms. However, few have examined the predictive utility of white matter integrity in the acute aftermath of trauma to predict prospective PTSD symptom severity in a mixed traumatic injury sample.

Method: Thus, the current study …

A Pilot Study Investigating Adopted Children’S Cultural Identity From Adopting Parents’ Perspective, Alyssa Mcveigh

Symposium of Student Scholars

Adopted children are faced with challenges of identity and a sense of belonging within their adopted family and environments. Research regarding adopted children suggests that their cultural identity is developed by the experiences they have within their biological culture such as, participating in holidays, meeting individuals who are from the same background or visiting their biological country. The goal of this pilot study was to explore the perspectives of adopting parents on their adopted children's cultural identity development, laying a foundation for the next study that will examine adopted children’s (college students) perspective. Ten adopting parents from The United States …

The Psychological Effects Of Israel’S Security Narrative On Palestinians In The West Bank And Gaza And Its Implications For Conflict Management, Gabrielle Childs

The Journal of International Relations, Peace Studies, and Development

Israel began constructing a separation barrier in 2003 in response to increasing terrorism and suicide bombings by the Palestinians during the Second Intifada (Dowty, 2005, p. 171). The separation barrier is an elaborate 400-mile security system of concrete walls, fences, barricades and checkpoints built to protect Israeli citizens (Vick & Arik, 2010). The wall portion of the barrier was constructed of thick reinforced concrete, stands approximately 25 feet tall, and separates the West Bank and Israel boundaries. There is bitter contention over whether the barrier was properly placed along the official partition boundaries. The concrete barriers were built in the …

A Minority Within A Minority: Exploring Identity Development In Relation To Mental Health Outcomes Within The Black Deaf Community, Nekolas Milton

Doctoral Dissertations

Black Deaf people are a double minority group that faces discrimination on multiple fronts. There is little literature on the relationship of cultural identity development and mental health concerns of this marginalized group. This study employs a mixed method approach to examine this relationship and explore the extant culturally tailored interventions targeted towards Black Deaf adults in a clinical setting. There were two phases of this project. Phase 1 included qualitative interviews with service providers of black deaf people to ascertain the type of culturally tailored interventions that are in place for this population. 5 themes emerged: systemic issues, mental …

The Role Of Previous Trauma To Stressful Media Encounters, Billy G. Dromgoole

Student Theses and Dissertations

Previous research has shed light on reexperiencing trauma via news coverage (Moyers, 1996). With the growing age of social media, it seems likely that the risk of such reexperiences via social media outlets could be high. Yet, there is a lack of research examining news coverage on social media and its role, if any. This study examined the role of previous trauma, and then the effect of viewing similar traumatic images provided by social media on vicarious trauma, negative affect, and state anxiety. Participants were randomly assigned to view either traumatizing videos (e.g., military or natural disaster videos) or neutral …

Internal Entrapment And Fearlessness About Death As Precipitants Of Suicidal Thoughts And Planning In The Context Of Post-Traumatic Stress Disorder (Ptsd), D Nicolas Oakey-Frost

LSU Master's Theses

The post-traumatic stress disorder (PTSD) and suicidal thoughts and behaviors (STB) relationship has been extensively studied but potential explanatory mechanisms remain inconclusive. Entrapment is one variable that evinces a theoretical and empirical mechanistic relationship with PTSD and STB. Further, entrapment and fearlessness about death (FAD) have not been linked but are hypothesized to interact in a way that facilitates vulnerability for intense suicidal thinking and potentially suicidal behavior. The current study examined the indirect effect PTSD symptoms have on suicidal ideation, planning, and likelihood of future suicide attempt through both internal (IE) and external entrapment (EE), moderated by levels of …

Investigating The Co-Evolution Of Individual And Network-Level Recovery Capital: A Dynamic Social Network Analysis Testing Network Cohesion And Exchange Theories, Mayra Guerrero

College of Science and Health Theses and Dissertations

Historically, treatment professionals, researchers, and policymakers widely regarded substance use disorders (SUDs) as acute conditions that patients could “recover” from after a single treatment. Recent efforts have redefined recovery as a lifelong, dynamic process that involves improvements in multiple domains over time. Thus, recovery capital frameworks and theory have gained momentum as a way to operationalize recovery from SUDs. Recovery capital is a multifaceted framework with theoretical underpinnings in the social capital literature that provides a way of conceptualizing and measuring the complexities of the recovery process. While the literature on recovery capital has grown significantly since its conception, the …

Measuring Allostatic Load In An Urban Adolescent Sample: The Profile And Role Of Biomarker Dysregulation In Depression Outcomes, Heather Marshall

College of Science and Health Theses and Dissertations

Accumulated, chronic stress exposure is well established as a precursor for allostatic load (AL). Both stress exposure and AL have been associated with depression in the existing literature. While many studies have focused on biomarkers representative of various physiological systems, a clear understanding of how physiological AL results in depression is yet unclear. Further, variability of hypo- and hypercortisolemic profiles have been associated with depression. A review of the existing literature supports hypocortisolemic profiles in relation to female depression and hypercortisolemic profiles in male depression across both adolescent and adult populations. The function of alpha-amylase (AA) dysregulation within the context …

Exploring The Effects Of Smoking Cessation Interventions For Asians And Asian Americans: A Meta-Analytic Review, Amber T. Pham

College of Science and Health Theses and Dissertations

Cigarette smoking continues to be a leading health problem in the United States and worldwide. Despite high prevalence rates among some subpopulations of Asians and Asian Americans, little attention has been focused on identifying effective smoking cessation interventions for this group. A meta-analysis examining effect sizes was conducted to test the hypothesis that smoking cessation interventions, overall, improve quit outcomes among Asians and Asian Americans. Factors associated with intervention effectiveness were explored through moderator analyses. Results show that overall, smoking cessation interventions are efficacious for Asians and Asian Americans (OR = 2.33). Moderator analyses revealed high intensity treatments and treatments …

Prenatal Stress & Socioemotional Outcomes In School-Aged Children: A Meta-Analytic Review, Michelle Anne Gilchrist

College of Science and Health Theses and Dissertations

Prenatal stress has been linked to a myriad of adverse obstetric, infant, and childhood outcomes. Several prospective studies have linked maternal stress and distress during pregnancy with long-term neurocognitive, behavioral, and emotional consequences for the offspring, including decreased cognitive abilities as well as symptoms of Attention Deficit/Hyperactivity Disorder (ADHD), depression, and anxiety. However, limited conclusions on the influence of type of stressors and the magnitude of the effect of prenatal stress on specific developmental trajectories can be drawn due to variation in study design and measured outcomes. This meta-analysis synthesized the state of the current literature and quantified the effects …

Parent And Child Language Profiles And Their Family And Clinical Predictors, Jesus Eduardo Solano-Martinez

College of Science and Health Theses and Dissertations

A large number of households in the United States include linguistic minority and immigrant parents. These include parents of Latinx backgrounds and their children who have varying levels of English and Spanish proficiency. Research is needed to examine the nature of parent-child language proficiency patterns and differences and their links to family processes and mental health. To address this gap, a sample of 294 Latinx parent-child dyads of predominantly low-income and immigrant backgrounds were interviewed and reported their English and Spanish language proficiency levels. Latent Profile Analysis (LPA) uncovered four parent-child language profiles including three in which there was a …

Lgbt Inclusivity In Transpersonal Psychology: A Case For Incorporating Lgbt Spiritual Experiences In Transpersonal Education, Daniel A. Seda, Phd

Journal of Conscious Evolution

After conducting three qualitative interviews on the somatic experiences of transgender individuals and finding relatively few resources with which to draw significant conclusions in the field, it is clear that Lesbian, Gay, Bisexual, and Transgender (LGBT) scholarship is severely lacking in transpersonal psychology.

Method: This research revealed that an understanding and appreciation for the lived experiences of gay people––specifically that of gay men––are also limited and are not appropriately represented through the use of feminist or queer models. Therefore, an alarming number of issues affecting the transgender and gay male populations are not being adequately addressed within the discipline of …

Exploring The Experience Of Anxiety Among Final Year Students At University: A Thematic Analysis, Catriona Keane, Daniel Waldeck, Andrew Holliman, Simon Goodman, Kubra Choudhry

The Qualitative Report

The transition from undergraduate study to a postgraduate career can be an anxiety provoking experience for many students. In this study, we explore the shared experience of five “anxious” undergraduate students as they transition from higher education towards their postgraduate careers. Using a qualitative methodology, semi-structured interviews were conducted with five female undergraduate students from different courses at a UK university. A thematic analysis revealed two overarching themes: perceived pressure without sufficient support, and concerns about next steps. The findings suggested the final year is emotionally demanding, and students felt as though there was a lack of provision to manage …

Cortical Microstructural Changes Associated With Treated Aphasia Recovery, Allen J. Chang, Janina Wilmonskoetter, Julius Fridriksson, Emilie R. Mckinnon, Lorelei P. Johnson, Alexandra Basilakos, Jens H. Jensen, Chris Rorden, Leonardo Bonilha

Faculty Publications

Objectives

To investigate the hypothesis that language recovery in post-stroke aphasia is associated with structural brain changes.

Methods

We evaluated whether treatment-induced improvement in naming is associated with reorganization of tissue microstructure within residual cortical regions. To this end, we performed a retrospective longitudinal treatment study using comprehensive language-linguistic assessments and diffusion MRI sequences optimized for the assessment of complex microstructure (diffusional kurtosis imaging) to evaluate the relationship between language treatment response and cortical changes in 26 individuals with chronic stroke-induced aphasia. We employed elastic net statistical models controlling for baseline factors including age, sex, and time since the stroke, …

Positron Emission Tomography From 1930 To 1990: The Epistemology And Process Of Scientific Instrumentation, Rick Shang

Arts & Sciences Graduate Student Theses and Dissertations

Positron Emission Tomography (PET) is a groundbreaking detection system that, among many other applications, enabled neuroscience researchers to detect and image physiological changes in the brain associated with cognitive operations as subjects perform a task. This technology helped researchers learn to explore the physiological basis of human cognition in new ways and was the immediate forerunner of functional Magnetic Resonance Imaging (fMRI), a technology that continues to dominate the neurosciences. PET was also the founding invention of a new field of cognitive science: human functional neuroimaging. Indeed, some would say that PET encouraged a particular way of understanding the brain …

Testing Candidate Cerebellar Presymptomatic Biomarkers For Autism Spectrum Disorder, Zoe Wilson Hawks

Arts & Sciences Graduate Student Theses and Dissertations

Background: Autism spectrum disorder (ASD) is a neurodevelopmental disorder diagnosed on the basis of social impairment, restricted interests, and repetitive behaviors. Contemporary theories posit that cerebellar-mediated error signaling impairments contribute to the causation of ASD. However, the relationship between infant cerebellar functional connectivity (fcMRI) and later ASD behaviors and outcomes has not been investigated. Such work is critical to establish early (presymptomatic) cerebellar correlates of ASD. Methods: Data from the Infant Brain Imaging Study (n=94, 68 male) were used to evaluate cerebellar fcMRI as a presymptomatic biomarker for ASD. Specifically, brain-behavior associations were analyzed for 6-month cerebellar connections in relation …

Stigma And Social-Emotional Health In Youth With Learning Differences, Kelsey Maki

Doctoral Dissertations

Youth diagnosed with specific learning disorder (SLD) and/or attention deficit hyperactivity disorder (ADHD), defined collectively for the purposes of this study as youth with learning differences, experience poorer social-emotional health outcomes in comparison to their typically developing peers. These youth additionally experience stigma from their peers, teachers, and broader community, which may impact social-emotional health. As a secondary data analysis of a larger study, the present study investigated the role of stigma consciousness alongside demographic variables, self-esteem, and peer relationships in social-emotional health outcomes. Due to the possible differences between youth diagnosed with SLD, ADHD, and comorbid SLD/ADHD, group differences …

The Mediating Role Of Interpersonal Skills In The Relationship Between Depressive Symptomatology And Dating Violence In Young Mothers, Lauren Catherine Wallace

Theses and Dissertations

Young mothers are an understudied group at high-risk for dating violence (DV) victimization and perpetration. Psychological distress, such as depression, increases young mothers' risk for DV (Thomas et al., 2019). In turn, depressive symptomology is associated with difficulties in interpersonal competence (Jones et al., 2019), which may increase DV risk (Bonache et al., 2017). In addition, young mothers may have few chances to learn the interpersonal skills associated with healthy adult romantic relationships due to a mismatch in developmental level and parenting status (Herrman et al., 2019; Moore et al., 2007). Using interpersonal stress generation theory (Hammen, 1991, 2006), we …

Independent Contributions Of Structural And Functional Connectivity: Evidence From A Stroke Model, Lynsey M. Keator, Grigori Yourganov, Alexandra Basilakos, Argye E. Hillis, Gregory Hickok, Leonardo Bonilha, Chris Rorden, Julius Fridriksson

Faculty Publications

Altered functional connectivity is related to severity of language impairment in poststroke aphasia. However, it is not clear whether this finding specifically reflects loss of functional coherence, or more generally, is related to decreased structural connectivity due to cortical necrosis. The aim of the current study was to investigate this issue by factoring out structural connectivity from functional connectivity measures and then relating the residual data to language performance poststroke. Ninety-seven participants with a history of stroke were assessed using language impairment measures (Auditory Verbal Comprehension and Spontaneous Speech scores from the Western Aphasia Battery-Revised) and MRI (structural, diffusion tensor …
