Association Between Lifetime Adverse Events, Emotion Dysregulation, Posttraumatic Stress Symptoms, Acculturation, And Chronic Pain: A Moderated Mediation Model, Miriam El-Haj

Theses and Dissertations

The association between traumatic experiences and chronic pain is well established. Lesser is known about how acculturation might affect this relation, specifically with Hispanics. In the present study, self-report measures on traumatic experiences, posttraumatic stress symptoms, emotion dysregulation, chronic pain, and acculturation were administered to 140 participants (71.4% females) aged 18–65 years old (M = 35.06, SD = 11.55), to determine whether acculturation moderates the relation between adverse lifetime experiences and chronic pain as mediated by posttraumatic stress symptoms and emotion dysregulation.

Those who were highly acculturated to the U.S. Anglo culture were higher on chronic pain than those who …

The Influence Of Neural Reward Processing On Memory In Depression, Nathan M. Hager

Psychology Theses & Dissertations

Theories and research suggest that depression involves impaired reward sensitivity and a deficit in memory for rewarding stimuli. Some researchers propose that this memory deficit may result from reduced neural reward sensitivity, which impairs the encoding of reward-related memories, but few studies have directly probed this connection. Such research may benefit from examining the reward positivity (RewP), an event-related potential (ERP) previously linked to reduced reward sensitivity in depression. Undergraduates with high or low self-reported depression completed a task in which they chose one of three doors, revealing a neutral word written in a color which indicated an outcome of …

Neuroticism And Stressful Life Events: Probing Mechanisms Underlying Vulnerability To Stress-Related Depression, Erin Bondy

Arts & Sciences Electronic Theses and Dissertations

Elevated neuroticism (N) potentiates the depressogenic effects of stressful life events (SLEs). We first replicate this association using longitudinal data (N=971 older adults) from the St. Louis Personality and Aging Network (SPAN) study. Here, SLEs prospectively predicted future depressive symptoms, especially among those reporting elevated N, even after accounting for prior depressive symptoms and previous SLE exposure (NxSLE interaction: p=0.016, ΔR²=0.003). These findings were further replicated in cross-sectional analyses of the Duke Neurogenetics Study (DNS), a young adult college sample with neuroimaging data (n=1,343: NxSLE interaction: p=0.019, ΔR²=0.003). Because evidence suggests that stress may promote depression …

Exploring The Links Between Social Anxiety And Depression In The Maintenance Of Romantic Relationships, Christian M. Hahn

Electronic Thesis and Dissertation Repository

Social anxiety is characterized by fear and avoidance of social encounters and has recently been associated with a variety of difficulties in romantic relationships. Complicating further investigation of these associations is the high degree of comorbidity between social anxiety and depressive symptomatology, which share several similarities in expression despite disparate underlying causes. The present thesis examines the unique influences of social anxiety and depression on a number of central aspects of relationship functioning and provide the first longitudinal investigation of the impacts of actor and partner social anxiety and depression on relationship quality and functioning. In Study 1, three independent …

Baseline And Stress-Induced Cognitive Control Deficits And Pro-Inflammatory Cytokines In Currently, Remitted, And Never Depressed Individuals, Katerina Rnic

Electronic Thesis and Dissertation Repository

Background: Cognitive theories posit that cognitive control deficits promote depression by reducing ability to self-regulate under stress. When activated by stress and accessible to working memory, negative cognitive content and structure (i.e., schemas), may interfere with cognitive control abilities, resulting in even greater declines in executive functioning. Moreover, burgeoning evidence indicates that social stress upregulates inflammation, resulting in a pro-inflammatory phenotype that drives depression pathogenesis. However, cognitive mechanisms underlying this process are not well understood. An objective of this study was to examine depression-related deficits in cognitive control and their association with poor self-regulation. Another purpose was to evaluate the …

A Developmental And Symptom-Level Approach To Comorbid Mental Health Disorders In Children, Elizabeth Thornley

Electronic Thesis and Dissertation Repository

This dissertation addresses current issues in the conceptualization and classification of childhood mental health issues (e.g., impact of sex/age on symptoms, comorbidity, limits of traditional models). In contrast to traditional models, the importance and value of utilizing individual symptoms as primary variables of interest is presented. This first study consisted of 9565 participants (M = 12.06, SD = 3.57, 58% males). Results for youth with no history of trauma indicated sex differences in symptom expression consistent with what has been previously shown in the literature; however, a complex presentation of attention-related symptoms was identified for females. Similar sex differences …

The Role Of Social Disconnection In The Relationship Between Perfectionism And Psychological Distress, Samantha Chen

Electronic Thesis and Dissertation Repository

This dissertation investigated the interpersonal mechanisms through which various aspects of perfectionism confer risk for psychological outcomes. Three studies were conducted based on the Perfectionism Social Disconnection Model (Hewitt, Flett, & Mikail, 2017), which proposes that individuals with higher levels of perfectionism may experience significant social disconnection, which then lead to a variety of maladaptive outcomes. Study 1 examined the longitudinal impacts of trait perfectionism and sense of relatedness on the variance in change in psychological outcomes. Findings showed that negative perceptions of relatedness partially mediated the link between socially prescribed perfectionism and psychological distress three months later; however, this …

The Impact Of Experimentally-Induced Perceived Discrimination On Substance Use, Kimberlye Elise Dean

LSU Doctoral Dissertations

Substance use disorders (SUDs) are among the most debilitating psychiatric disorders. Although prevalence rates of SUDs are similar between White and Black adults, these groups experience differential treatment outcomes (e.g., Black adults with SUDs are more likely to report greater pre- and post-treatment substance use). Examining culture-specific correlates of racial differences in substance use is vital to improve understanding of the etiological and maintaining mechanisms of SUDs among Black adults. Perceived racial discrimination (PRD) is prospectively related to various substance use-related outcomes. Thus, some may use substances to alleviate psychological distress (e.g., anxiety) associated with PRD, which may over time …

Exploring Clinical Psychology Doctoral Students’ Knowledge And Attitudes About Older Adult Sexuality, Lindsey Horta

Doctoral Dissertations

The current study surveyed clinical psychology doctoral students’ (N=291) knowledge and attitudes about older adult sexuality. Knowledge and attitudes were measured using the Facts of Aging Quiz, the Aging Sexuality Knowledge and Attitudes Scale, Attitudes Towards Sexuality Scale, and measures to explore students’ exposure to and interests in the older adult population, as well as academic and clinical exposure (coursework, practicum opportunities and clinical contacts with older adults) to the older adult population and older adult sexuality. Generally, students’ knowledge about aging was associated with their attitudes about older adult sexuality; the more knowledge a student has about older adult …

Emotional Response To Negative Mood Induction In Mild Cognitive Impairment And Cognitively-Intact Older Adults, Gennarina Diane Santorelli

Doctoral Dissertations

Older adults with mild cognitive impairment (MCI) report greater rates of psychiatric symptoms than cognitively-intact older persons. This may be associated with emotion dysregulation, which is prevalent in cognitively-impaired populations. No research to date has investigated responses to emotionally-provocative stimuli in persons with MCI. Aim 1 of this study determined differences in emotional reactivity to and recovery from negative mood induction in older persons with amnestic MCI (aMCI) and cognitively-healthy older adults. Moreover, emotion dysfunction in MCI may be linked to impairment in executive function (EF), a common feature of MCI. Theoretical models postulate that EF is essential to the …

Trajectories Of Depressive Symptoms Among Low-Income Perinatal Women: The Role Of Father Involvement, Hillary Halpern

Doctoral Dissertations

The present study sampled a racially diverse group of 207 women at five time points from the third trimester of pregnancy until one year postpartum. Group-based developmental trajectory modeling was used to examine unique trajectories of women’s depressive symptoms (CES-D) across the perinatal period. Analyses yielded four distinct depression trajectory groups, conceptualized as the low symptom group, the intermediate symptom group, the desist-return group, and the chronic depression group. Next, fathers’ roles were examined as predictors of maternal depression trajectories in resident- and non-resident father families. Specifically, aspects of father involvement were assessed as predictors of women’s membership to …

In Search Of Psychiatric Kinds: Natural Kinds And Natural Classification In Psychiatry, Nicholas Slothouber

Electronic Thesis and Dissertation Repository

In recent years both philosophers and scientists have asked whether or not our current kinds of mental disorder—e.g., schizophrenia, depression, bipolar disorder—are natural kinds; and, moreover, whether or not the search for natural kinds of mental disorder is a realistic desideratum for psychiatry. In this dissertation I clarify the sense in which a kind can be said to be “natural” or “real” and argue that, despite a few notable exceptions, kinds of mental disorder cannot be considered natural kinds. Furthermore, I contend that psychopathological phenomena do not cluster together into kinds in the way that paradigmatic natural kinds (e.g., chemical …

Exploring The Effects Of Age In A Drosophila Melanogaster Model Of Traumatic Brain Injury, Andrea Maria Briseño

Loma Linda University Electronic Theses, Dissertations & Projects

Traumatic brain injury (TBI) is one of the leading causes of death worldwide and can lead to immediate and long-term behavioral, physical, and cognitive deficits. Our laboratory has previously characterized the neuropathological and behavioral consequences of mild-to-severe TBI in rodents of varying ages. To develop a high-throughput platform upon which to test the effects of therapeutic interventions, we have recently begun to assess behavior and physiological parameters in a Drosophila melanogaster (fruit fly) model using a simple spring-loaded high impact trauma (HIT) device as a model of blunt force trauma. Drosophila (young, middle, and old) received either TBI or a …

The Impact Of Alcohol- Related Consequences On Alcohol Use Behaviors, Amy Cuccuro

Objectives: Primary objectives of the present study include (1) exploring the impact of alcohol-related consequences on current drinking behaviors, and (2) examining perceptions of consequences and their relationship to current drinking behaviors. Method: Original data collected through online self-report surveys from 579 participants (Mage = 28.0 years) was utilized for the present study. Each participant answered brief questionnaire about their current alcohol use (quantity and frequency) using the AUDIT (Alcohol Use Disorders Identification Test) and follow up questions about their prior alcohol related experiences and subsequent perceptions. Results: There was a significant association between AUDIT scores and prior experiences of …

Planning For Healthcare Quality Using Procurement As A Strategy: A Case Study Exploring An Outcomes-Oriented Approach To Healthcare Procurement, Kassandra A. Alia

Theses and Dissertations

The United States has one of the most costly healthcare systems in the world, yet also ranks lower in patient outcomes in comparison with many other developed countries. A focus on quality implementation may help accelerate ongoing efforts to improve healthcare quality. The overall purpose of this study was to explore outcomes-oriented contracting as a mechanism for embedding quality implementation planning proactively into the process for procuring healthcare services. A single case study methodology was utilized to examine changes in procurements over time following implementation of an outcomes-oriented contracting approach within an organization that provides funding for behavioral health and …

The Effects Of Historical Alcohol Use On Neuropsychological Functioning In Older Adults Following A Traumatic Brain Injury, Ryan Sever

Dissertations

The present study aimed to determine the effects of alcohol abuse and dependence in long term functioning of older adults who have experienced a moderate to severe traumatic brain injury. The research question being answered in the current study was if a history of alcohol abuse or dependence would worsen neuropsychological functioning in older adults who experienced at least one moderate to severe traumatic brain injury. Participants of the study were selected from the more extensive database provided by the Brain Aging in Vietnam War Veterans (DOD-ADNI) database. All participants were Vietnam War veterans between the ages of 61 and …

Body Dissatisfaction, Perceived Smoking Consequences, And Weight Control Smoking, Samantha N. Martinez

Loma Linda University Electronic Theses, Dissertations & Projects

Eating disorders are a significant public health concern affecting approximately 8 million individuals in the United States, with women suffering at disproportionate rates. Eating disorders have been associated with a variety of negative health behaviors, including smoking. Despite an overall decrease in smoking prevalence, smoking rates remain high among females with eating disorders. The current study explored the role that perceived consequences of smoking related to appetite/weight control plays in moderating the relationship between body dissatisfaction, which is a risk factor for the development of an eating disorder, and weight control smoking, controlling for the effects of race/ethnicity smoking status, …

Electroencephalographic Asymmetry, Emotion Regulation, And Their Relationships With Depression Risk, Aliza Jacob

Dissertations, Theses, and Capstone Projects

Background: Research investigating patterns of electroencephalographic (EEG) brain asymmetry aids our understanding of neural systems involved in the processing of emotion, motivation, and psychopathology. Withdrawal-motivated negative emotions characteristic of depression are associated with relative right prefrontal cortex (PFC) activity, whereas approach- motivated positive emotions are associated with relative left PFC activity. Styles of emotion regulation (ER), or modulation of the intensity and duration of emotional responses, are also associated with presence (e.g., suppression, or maladaptive ER) versus absence (e.g., cognitive reappraisal, or adaptive ER) of depression vulnerability. Most PFC asymmetry studies of emotion, depression, and/or ER rely upon EEG recorded …

The Development Of Face Morphing Task To Assess Self Other Differentiation, Esen Karan

Dissertations, Theses, and Capstone Projects

Self-Other Differentiation (SOD) refers to a developmental process of acquiring a consolidated, integrated, and individuated sense of self. SOD develops at a) perceptual (e.g., facial perception) and b) representational (e.g., traits, mental states, and beliefs) levels. Impairments in representational SOD (R-SOD) are associated with many forms of psychopathology, particularly borderline personality disorder (BPD) and narcissistic personality disorder (NPD). Few studies to date have examined the perceptual aspects of SOD (P-SOD), which are hypothesized to develop from infancy onwards in tandem and in interaction with R-SOD. Given that the human face is one of the key characteristics that humans use to …

The Relationship Between Cognitive Function And Activities Of Daily Living, Pamela V. Lorenzo

Loma Linda University Electronic Theses, Dissertations & Projects

Dementia is a cognitive disorder that can be caused by several underlying diseases, including Alzheimer’s disease and vascular disease. Dementia is not only characterized by declines in cognition, but is also associated with declines in instrumental and basic activities of daily living (ADLs). Cognitive decline generally begins prior to any declines in ADLs, and as cognitive impairments progress, the ability to independently perform ADLs begins to decline as well. Accurate assessment of ADL functioning, though critical to the diagnosis of dementia, can be difficult with the use of self-report measures. One objective measure of ADLs is the Functional Independence Measure …

Getting The Benefit Of The Doubt: The Effect Of Randomization Ratio On The Placebo Response, Taiki Matsuura

Dissertations, Theses, and Capstone Projects

Placebos are commonly employed in clinical trials as inactive treatments to which experimental treatments are compared against in order to control for psychological “noise.” Randomized double-blind placebo control studies are considered the “gold standard” in epidemiologic research because they can provide the strongest possible evidence of causation if designed correctly (Hulley, Cummings, Browner, & Grady, 2007). One phenomenon that poses a threat to the integrity of this evidence is the placebo response (PR), or referred to as the “placebo effect.” Expectancy is considered a central PR mechanism and boasts the most empirical support among all proposed mechanisms. Expectancy is not …

The Complexity Of The Bilingual Experience: Linguistic Variables Predict Cognition In Older Adults, K'Dee D. Elsen

Loma Linda University Electronic Theses, Dissertations & Projects

Background: It has been estimated that more than half of the world’s population is bilingual. With the rates of bilingualism exponentially growing, researchers have been increasingly interested in the effects of bilingualism on the brain. Although the literature continues to expand, it remains limited in its understanding of how the complex bilingual experience impacts cognition. Objective: The current study, therefore, will focus on investigating how the bilingual experience affects cognition, specifically the cognitive domains of executive functioning and linguistic processing within an older adult population. Methods: Participants were 144 healthy older adults (67% female) between the ages …

Does Ethnic Identity, In-Group Preference, And Acculturation Protect Latinas With A History Of Interpersonal Trauma From Developing Symptoms Of Ptsd?, Evelyn M. Ramirez

Dissertations, Theses, and Capstone Projects

Previous research suggests ethnic identity, a sense of belonging to a particular cultural group, may be protective against symptoms of post-traumatic stress disorder (PTSD). However, the role of ethnic identity, in-group preference (i.e., an individual’s preference for interactions with members of their own ethnic group) and acculturation (i.e., the level of comfort with the mainstream culture) have not been investigated as protective factors for Latinas with a history of interpersonal and sexual trauma. In this study, ethnic identity, in-group preference and acculturation were assessed via self-report on the Scale of Ethnic Experience in two samples of undergraduate Latina and non-Latina …

Education And Social Support As Mediators Of Function And Cognition In Patients With Schizophrenia, Spring Flores Johnson

Loma Linda University Electronic Theses, Dissertations & Projects

Schizophrenia affects an estimated 1% of the population worldwide and the devastating symptoms impact a patient’s daily functioning, social and interpersonal relationships, cognitive abilities, and overall quality of life (American Psychiatric Association, 2000). Additionally, patients with schizophrenia can struggle to maintain employment and live independently due to low cognitive ability and functional capacity. Given the pervasive and deleterious impact of schizophrenia, it is imperative to address the functional toll this diagnosis can have on those suffering with the disorder to develop helpful strategies that increase functional capability. The goal of this study is to determine the impact symptom severity has …

Dermatoglyphic Measures In Relation To Depressive Symptoms Among Non-Clinical Adolescents And Young Adults, Yosefa A. Modiano

Dissertations, Theses, and Capstone Projects

Depressive disorders are highly prevalent and can be devastating. Increasingly, depressive symptomatology is understood from a dimensional perspective such that non- or sub-clinical presentations may share a similar etiology. Depression etiology is believed to include genetic and environmental factors that may contribute to underlying vulnerability (diathesis) by way of neurodevelopment. Birth cohort studies have provided empirical evidence of the relationship between prenatal insult and later experience of adverse outcomes, including increased risk for depressive disorders. Retrospective investigation of the possible influence of prenatal disturbance on later experience of depressive symptoms has methodological limitations. Dermatoglyphic measurements offer a more methodologically viable …

Investigating The Feasibility Of Advanced Law Enforcement Resilience Training (A.L.E.R.T.): An Innovated And Practical Intervention To Enhance Police Mindfulness And Resilience, Stephanie B. Stern

Dissertations, Theses, and Capstone Projects

Policing is thought to be one of the most stressful occupations. Without effective strategies to cope with chronic work-related stress, police are vulnerable to developing mental and physical health problems. The police literature and research highlights the need for proactive, evidence-based interventions to help police maintain their resilience throughout their careers. The current study sought to bridge a gap between police literature, research and practice by developing and testing the feasibility of using the Advanced Law Enforcement Resilience Training (A.L.E.R.T.) mobile app to help police learn and practice mindfulness skills after engaging in a brief in-person training. Using a pre-test, …

Examining The Effects Of A Multi-Component Neurocognitive Intervention For School-Aged Children With Co-Occurring Adhd And Reading Difficulties, Alyssa L. Chimiklis

Dissertations, Theses, and Capstone Projects

Objective: Children with attention deficit hyperactivity disorder (ADHD) frequently exhibit impairments in neurocognitive pathways (i.e., deficits in sustained attention, response inhibition, processing speed, working memory, and cognitive flexibility). There is also extensive support indicating that youth with co-occurring ADHD and reading difficulties share pathological pathways and exhibit deficits in executive functions. Neither behavioral nor pharmacological interventions have been able to fully address executive dysfunction and/or reading deficits in this population. Computerized neurocognitive training interventions have been explored as a treatment alternative for youth with pure ADHD and have demonstrated some merit. Conceptually, computerized neurocognitive training programs that target overlapping pathways …

The Social Cost Of Pain: Rejection Sensitivity, Social Rejection, And Cannabis Use In Young Adults, Naomi Dambreville

Dissertations, Theses, and Capstone Projects

Cannabis has been implicated in relieving distress and social pain, an important area of research in young adult samples, given the saliency of peer and social networks to addiction. Cannabis, via opioid pathways, has been shown to reduce, or potentially buffer, the effects of social pain and rejection. Thus, cannabis may be protective against the painful feelings of social stress, particularly for heavier or more frequent users. However, findings are not wholly positive, as other research indicates cannabis may blunt affective responses and impair social processing. The effects of cannabis use in young adults are understudied, as well as its …

Fatalism And Pain Experience In Hispanic And Non-Hispanic White Patients With Chronic Pain, Esmeralda Ibette Nuñez

Loma Linda University Electronic Theses, Dissertations & Projects

The purpose of this dissertation was to explore fatalistic beliefs about pain among Hispanic and Non-Hispanic White (NHW) patients with chronic pain in order to assess the assertion that fatalism is a uniquely important cultural determinant of pain experience among Hispanics. Hypotheses were that across both Hispanic and NHW patients, lower socioeconomic status and lack of access to a usual source of healthcare for chronic pain, rather than ethnicity, would relate to greater pain fatalism. Secondly, it was hypothesized that greater pain fatalism would relate to higher pain severity and pain interference for both groups. Pearson product-moment correlations were used …

Subjective Experience Of Autonomy And Psychological Well-Being: A Cross-Cultural Study With Korean American And European American Young Adults, Esther J. Lee

Dissertations, Theses, and Capstone Projects

This study aimed to explore whether parenting beliefs and practices that might promote academic or professional achievements also undermine aspects of psychological well-being. Specifically, the study focused on the relationship between the experience of subjective autonomy and psychological well-being measured in terms of self-esteem, flourishing, and life satisfaction. The sample consisted of 86 second-generation Korean Americans (KAs) and 99 European Americans (EAs) ages 25-35. Perceived parental autonomy support (versus psychological control) and perceived parental modernity (versus traditionalism) were also examined for group differences and associations with psychological well-being. As a group, KAs perceived greater parental psychological control and parental traditionalism …
