Medical Interpreters' Experience Working With Distressed Families In Pediatric Settings, Paulina Lim

Theses and Dissertations

Effective communication between families and pediatric clinicians is essential for mitigating family stress and improving quality of care. Families who speak a primary language other than English must contend with the added stress of language barriers during stressful encounters, which could impact the quality of patient care and health outcomes. Trained medical interpreters facilitate communication, including distress expressions, during interpreted medical encounters (IME). Little is known about how interpreters identify distress and what factors impact distress identification during IME. This project describes how interpreters identify distress of families during IME, and how they identify cultural nuances in distress expression and …

Behavioral And Eye-Movement Correlates Of Item-Specific And Relational Memory In Autism, Greta Nicole Minor

Theses and Dissertations

Recent work has challenged past findings that documented relational memory impairments in autism. Previous studies have often relied solely on explicit behavioral responses to assess relational memory integrity, but successful performance on behavioral tasks may rely on other cognitive abilities (e.g., executive functioning) that are impaired in some autistic individuals. Eye-tracking tasks do not require explicit behavioral responses, and, further, eye movements provide an indirect measure of memory. The current study examined whether memory-specific viewing patterns toward scenes differ between autistic and non-autistic individuals. Using a long-term memory paradigm that equated for complexity between item and relational memory tasks, participants …

Pinpointing The Cognitive Structure Of The Cpt-3: A Case For Distribution Appropriate Statistical Methods, Chandler J. Zolliecoffer

Theses and Dissertations

The present study used the CPT-3 as a model to illustrate the complementary use of distribution-appropriate statistical methods to analyze non-normally distributed empirical datasets. Study results reaffirmed that while group-level analysis (e.g., via traditional parametric group-level analysis or distribution-appropriate group-level analysis procedures) offers insights into performance of the group in aggregate, it is oftentimes inappropriate to presume that patterns reflected by the group are, necessarily, applicable to a smaller subset of respondents. Thus, understanding how subgroups within the population navigate and approach a given task can have direct implications for more personalized/individualized assessment and treatment, especially in clinical and research …

Impact Of Childhood Maltreatment And Endocannabinoid Function On Posttraumatic Stress Symptoms In Traumatically-Injured Adults, Elizabeth Parisi

Theses and Dissertations

The ECSS plays a crucial role in regulation of the stress response, is modulated by exposure to acute and chronic stressors, and shows potential as a biomarker for PTSD. Changes in ECSS function are apparent in adults with a history of childhood maltreatment. Further, childhood maltreatment is a well-established pre-trauma risk factor for development of PTSD following a traumatic event in adulthood. No study to date has examined the contribution of ECSS function to the relationship between childhood maltreatment and PTSD following a subsequent trauma in adulthood. The current study aimed to investigate the relationship between exposure to threat and …

The Impact Of Racial Discrimination And Peritraumatic Dissociation On The Development Of Ptsd Symptoms, Farah Harb

Theses and Dissertations

Racial discrimination is a traumatic stressor that increases risk for posttraumatic stress disorder (PTSD), but mechanisms to explain this relationship remain unclear. Peritraumatic dissociation, the complex process of disorientation, depersonalization, and derealization during a traumatic event, has been found as a consistent predictor of PTSD. Experiences of racial discrimination may force many Black Americans to detach from their environment to mitigate stress and protect their well-being, which, in turn, increases risk for dissociation. However, this has not been specifically explored with peritraumatic dissociation. The current study explored the role of peritraumatic dissociation in the impact of racial discrimination on PTSD …

Acceptability And Feasibility Of Telehealth Delivered Written Exposure Therapy With College Students, Maya Anais Krek

Theses and Dissertations

Full and subthreshold presentations of posttraumatic stress disorder (PTSD) are both functionally impairing and chronic. Therefore, development of feasible and acceptable treatments for both is imperative. Written Exposure Therapy (WET), a brief five-session in-person PTSD treatment, has the potential to be successfully administered accessibly via a telehealth format due to minimal therapist contact and short duration of treatment. This study explored the feasibility and acceptability of WET delivered via a telehealth format to college students experiencing posttraumatic stress symptoms.

Participants (N = 4) were college students who were impacted by at least one traumatic event and had associated posttraumatic stress …

Utilizing Structural Equation Modeling To Examine Factors Impacting Health-Related Quality Of Life For Emerging Adults With Chronic Pain As They Transition To Adulthood, Amy Coral Lang

Theses and Dissertations

Approximately 5% to 30% of adolescents and emerging adults are living with chronic pain as they navigate the transition from pediatric- to adult-focused health care. However, there is a paucity of research investigating the health care transition experience for emerging adults with chronic pain. The current study aimed to utilize structural equation modeling in a sample of community-recruited emerging adults with chronic pain to: 1) assess a hypothesized measurement model and validate pertinent measures in this understudied population; and 2) assess a hypothesized structural model based in the Individual and Family Self-Management Theory. Findings provide preliminary validation of measures of …

The Impact Of Emotional Cues On Response Inhibition In Obsessive-Compulsive Symptoms, Ashleigh M. Harvey

Theses and Dissertations

Response inhibition (RI; the ability to inhibit a pre-potent response) has been proposed as a cognitive vulnerability underlying obsessive-compulsive disorder (OCD). However, extant mixed findings about this purported relationship have raised questions of how robust this relationship might be, and whether other contextual factors may not be fully captured by existing study methodologies. Given rates of comorbid depression and real-world clinical observations of the effects of dysphoric mood on OCD, the present study examined the associations between RI, OCD, and dysphoric mood by utilizing an analogue sample and a cross-sectional, within-subjects design. Participants completed the stop-signal and go/no-go tasks to …

The Relationship Between Response Inhibition Deficits And Intimate Partner Violence Perpetration, Bryce Arseneau

Theses and Dissertations

Victims of intimate partner violence (IPV) perpetration suffer from lasting deleterious impacts of trauma. Although various risk factors of IPV have been explored, fewer studies have focused on executive functioning as potential risk factors for IPV perpetration. Response inhibition is a form of cognitive control which serves to stop the initiation of a maladaptive action/response. Within the context of IPV, adaptive response inhibition may inhibit utilizing aggression as a conflict strategy. Therefore, exploring the relationship between response inhibition deficits and IPV may further our understanding of IPV perpetration.

This study sought to explore the relationship between response inhibition and IPV …

Cross-Day Associations Between Relational Factors And Intimate Partner Violence In Young Adult Couples, Lauren Grocott

Theses and Dissertations

The prevalence of intimate partner violence (IPV) is alarmingly high, with young adults at increased risk, underscoring the importance of identifying risk factors for perpetration of IPV. IPV is largely understood as a dyadic process, as it involves both partners and is inherently influenced by the behaviors of both partners. Thus, it is important that research poised to better understand risk factors for IPV utilize young adult samples that include both dyad members. Previous research examining risk factors for IPV perpetration has identified multiple relational factors (i.e., relationship characteristics influenced by both partners) that impact risk. In particular, findings suggest …

Anti-Bisexual Discrimination, Hazardous Alcohol Use, And Sexual Victimization Among Bi+ Individuals, Benjamin Katz

Theses and Dissertations

Bi+ individuals are at an elevated risk of sexual victimization compared to other sexual minorities. Hazardous alcohol use and minority stress are two factors proposed to contribute to increased rates of sexual victimization among bi+ individuals. The present study investigated the roles of distal and proximal minority stress, general life stress, negative affect, and hazardous alcohol use as predictors of sexual victimization in a sample of 192 bi+ young adults. Results indicated that experiences of anti-bisexual discrimination were associated with an increased likelihood of experiencing past year rape victimization. A direct, positive association between hazardous alcohol use and past year …

Alcohol Use, Trait Anger, And Intimate Partner Violence In College Student Couples, Cayla O'Hair

Theses and Dissertations

Intimate Partner Violence (IPV) is a significant public health problem, and risk for IPV is often highest among young adults. Numerous studies have found alcohol use to temporally precede and increase the risk for IPV perpetration. Trait anger is also associated with greater levels of physical, sexual, and psychological IPV perpetration. Daily diary research using one member of the dyad has found that alcohol is associated with increased physical IPV perpetration among men high, but not low, in levels of trait anger. However, IPV is a dyadic process that is impacted by the behavior of both partners, and little is …

The Cumulative Impact Of Childhood Adversity On Bold Responses To Inhibitory Control During Early Adolescence In The Abcd Study Cohort, Elizabeth Ashley Stinson

Theses and Dissertations

Adolescence is characterized by dynamic neurodevelopment, which poses opportunities for risk and resilience. Adverse childhood experiences (ACEs) pose additional risk to the developing brain, where ACEs have been associated with alterations in functional magnetic resonance imaging (fMRI) BOLD signaling in brain regions underlying inhibitory control. Potential resiliency factors, like positive family environment, may attenuate the risk associated with ACEs. Using baseline to 2-year data from the Adolescent Brain Cognitive Development (ABCD) Study, the current study examined how ACEs relate to fMRI BOLD signaling during successful inhibition on the Stop Signal Task (SST) in regions underlying inhibitory control during early adolescence …

Characterizing Coping Among Parents Of Children With Medical Complexity, Julia Barbara Tager

Theses and Dissertations

Children with medical complexity (CMC) are characterized by intensive healthcare needs. Given the centrality of the relationship between parent and child well-being, an investigation of the experiences of parents who care for CMC is warranted. Parents of CMC experience significant challenges relating to practical matters and their own well-being, but there is a dearth of research examining parental coping strategies used in response to these challenges. Informed by the revised Transactional Model of Coping, the current study aimed to characterize coping among a sample of parents of CMC. Twenty parental caregivers of CMC served by the Complex Care Program at …

Patterns Of Therapist Use Of Play And Humor And Child Behavioral Fear Response In An Exposure Therapy For Children With Williams Syndrome, Brianna Young

Theses and Dissertations

Children with Williams syndrome struggle with fears and phobias that significantly impact their daily lives. Yet there are few psychosocial and no empirically supported behavioral interventions to treat anxiety and phobias in this population of children. This study is part of a larger project examining the effectiveness of an exposure-based play- and humor-infused intervention aimed to provide developmentally appropriate behavioral therapy to reduce fear and anxiety in children aged 4 to 10 with Williams syndrome. This approach was piloted with 9 children (3 females; 6 males) in the context of developing a website to disseminate the approach to university-based and …

The Role Of Alcohol Use, Drinking Context, And Alcohol Expectancies In Sexual Assault Perpetration Among College Men, Joseph D. Censor

Theses and Dissertations

Sexual assault is a major public health and criminal justice problem in our society. The high prevalence rate of sexual assault victimization and perpetration among college students is even more disturbing. Additionally, the prevalence of alcohol use among college students is higher than in the general population, and alcohol use is associated with more than half of sexual assaults. The goal of the present study was to gain a deeper understanding of the role of various alcohol related factors in sexual assault perpetration among college men. Specifically, this study assessed the association of perpetration with general problematic alcohol use, general …

Resting State Functional Connectivity In The Default Mode Network: Relationships Between Cannabis Use, Gender, And Cognition In Adolescents And Young Adults, Megan Ritchay

Theses and Dissertations

Introduction: Cannabis is the most commonly used illicit substance in the United States, and nearly 1 in 4 young adults are current cannabis users. The psychoactive component of cannabis, THC, is active at cannabinoid receptors, type 1, or CB1 receptors. CB1 receptors play a critical role in neural development, and chronic cannabis use causes desensitization and downregulation of these receptors. Chronic cannabis use is associated with changes in resting state functional connectivity (RSFC) in the default mode network (DMN) in adolescents and young adults, although results are somewhat inconsistent across studies, likely due to differing methodologies. Additionally, cannabis effects appear …

The Influence Of Relationship History On Sexual Consent: A Comparison Of Idealized And Actual Sexual Experiences, Cari Beth Lee

Theses and Dissertations

Objective: The study assessed how sexual consent varied from imaginary ideal scenarios and actual sexual experience while taking into consideration gender and relationship status. Methods: College students completed an online survey in which they were randomized to one of two imaginary scenarios in which they were about to have sex in an ideal setting with either their most recent sexual partner or a new sexual partner. Participants were asked what external consent behavior they would use to indicate their consent and to rank which consent behaviors they considered the most important for indicating their consent. They were also asked to …

Functional Responding To Appetitive Faces Among Cannabis-Using Adolescents And Young Adults, Ryan Michael Sullivan

Theses and Dissertations

Cannabis use is associated with attenuated reward signaling, yet few studies have examined this relationship when viewing rewarding appetitive faces while undergoing functional neuroimaging. Furthermore, few neuroimaging analyses have examined the moderating role of gender on task-based fMRI outcomes. This study explored functional BOLD response elicited by appetitive faces while engaged in an affective go/no-go task, and specifically investigated the differences between cannabis-using and control groups, whether gender moderate findings, and brain-behavior associations. Participants (ages 16-26 years) were scanned after at least 3-weeks of monitored abstinence (cannabis-using group = 35; control group = 33). The findings demonstrated aberrant activation in …

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 …

Identification And Response To Parent Distress By Medical Providers In The Pediatric Intensive Care Unit, Kathryn Anne Balistreri

Theses and Dissertations

During hospitalization in the pediatric intensive care unit (PICU), approximately 25-60% of parents experience clinical levels of distress (i.e., traumatic stress, anxiety, and depression). Despite this, PICU providers rarely refer parents to formal psychological services, and parents describe room for improvement in provider response to their emotional needs. Difficulty identify and/or responding to distress in parents may contribute to these deficiencies. The present study aimed to evaluate how medical providers identify and respond to parent distress in the PICU. Thirty-seven medical providers (78% female; 73% White) from the Children’s Wisconsin PICU completed a semi-structured interview. Providers perceived supporting distressed parents …

Proactive And Reactive Cognitive Control Under Threat Of Unpredictable Shock: A Combined Eye-Tracking And Eeg Study Using Multilevel Modeling, Salahadin Lotfi

Theses and Dissertations

We are constantly bombarded by environmental distractors in daily life which interfere with internal, ongoing goals, thus cognitive control processes need to be in place to adapt to maintain these goals in light of the environmental demands. These cognitive processes (generally referred to cognitive control) are thought to be adjusted reactively or proactively to deal with distractors. There is little evidence on how state anxiety dynamically interacts with these two modes of cognitive control. Taking advantage of a multimodal methodology, through two experiments, we replicated existing findings of reactive and proactive control processes via utilizing a Flanker task in a …

Data-Driven Approach To Dynamic Resting State Functional Connectivity In Post-Traumatic Stress Disorder, Carissa Weis

Theses and Dissertations

Posttraumatic stress disorder (PTSD) is a heterogenous psychological disorder that may result from exposure to a traumatic event. Using functional magnetic resonance imaging (fMRI), symptoms of PTSD have been associated with aberrations in brain networks that emerge in the absence of a given cognitive demand or task, called resting state networks. Most previous research in resting state networks and PTSD has focused on aberrations in the static functional connectivity among specific regions of interest (ROI) in the brain and within canonical networks constrained by a priori hypotheses. However, dynamic fMRI, an approach that examines changes in brain network characteristics over …

Stability And Predictive Value Of Intellectual Functioning In Neurofibromatosis Type 1 Beginning In The Preschool Years, Gregor Nathanael Pau Schwarz

Theses and Dissertations

Neurofibromatosis type 1 (NF1) is a rare genetic disorder that affects multiple aspects of cognitive functioning, including intellectual functioning, attention, and executive functioning. The predictive value of intellectual functioning (IF) in the preschool years for IF in the school- age and early adolescent years has not been examined in youth with NF1. In this study, the reliability and predictive value of preschool IF for school-age IF were examined using both bivariate correlation and more complex linear mixed models. The participants were 55 youth with NF1 from ages 3 to 13 years. Intellectual functioning was measured with the Differential Ability Scales …

Utilizing Cognitive Assessment To Predict Exposure And Response Prevention Treatment Response, Gregory Samuel Berlin

Theses and Dissertations

Exposure and response prevention (ERP) is the first-line treatment for the obsessive-compulsive disorder (OCD). However, a substantial portion of individuals in treatment may not see benefit, and efforts to find predictors of treatment outcomes have been challenging. Response inhibition (RI), which has been linked to OCD symptoms, is theoretically promising as a predictor of ERP treatment outcomes. In this study, we utilized inhibitory capabilities, measured at admission to partial hospitalization programs (PHP) at Rogers Memorial Hospital, to predict treatment outcomes in ERP. We hypothesized that worse performance in RI subdomains of action cancellation, action withholding, and interference control, as well …

The Association Of Aerobic Fitness With Resting State Functional Connectivity And Verbal Learning And Memory In Healthy Young Adults, Kyle Joseph Jennette

Theses and Dissertations

The beneficial effects of exercise and cardiopulmonary fitness on general health, quality of life, and reduction of mortality are well known in older adults. There is evidence to support the positive effects of exercise and aerobic fitness on psychiatric and neurocognitive function in children, adults, and older adults. Indeed, many studies have explored the positive effects of aerobic fitness on slowing cognitive decline associated with normal and pathological aging. However, comparatively fewer empirical studies in the literature exist to support and understand the effects of aerobic fitness on the developing brain, particularly during adolescence and young adulthood, especially as it …

Factors Contributing To Executive Functioning In Children With Neurofibromatosis Type 1, Brianna Yund

Theses and Dissertations

Despite variability in the neurofibromatosis type 1 (NF1) cognitive phenotype, attention and executive functioning (EF) difficulties are often described, and high rates of attention-deficit/hyperactivity disorder (ADHD) have long been associated with NF1. Despite the known clinical relation between NF1 and ADHD, there is a paucity of research exploring potential factors that contribute to ADHD vulnerabilities in children and adolescents with NF1. Furthermore, recent research suggests that impairment in EF, a construct highly associated with ADHD, occurs in children with NF1 independent of ADHD diagnosis suggesting that the presence of EF impairment in children with NF1 may not be uniquely associated …

Treatment Predictors Of Dialectical Behavior Therapy Among Adolescent Females In Residential Care, Taylor Davine

Theses and Dissertations

Dialectical Behavior Therapy (DBT) is a comprehensive intervention for the treatment of borderline personality disorder (BPD), which is characterized by significant emotion dysregulation and associated parasuicidal behaviors. Findings from 21 randomized-controlled trials indicated that DBT is effective in the treatment of BPD symptoms. While effective, some individuals do not obtain symptoms reductions after completing DBT. The aim of the current study was to identify factors that predict treatment response among adolescent females (N = 107) receiving DBT in a residential setting. It was hypothesized that residents with elevated scores of emotion regulation difficulties, intolerance of uncertainty, experiential avoidance, social anxiety …

A Psychometric Evaluation Of Computerized Attention Measures In Young Children With Neurofibromatosis Type 1, Sara Katharine Pardej

Theses and Dissertations

Children with neurofibromatosis type 1 (NF1) often demonstrate difficulties with attention and executive functioning that can be evident even starting at a young age. Despite this consistent finding in the literature, there has been no research to determine which measures of attention are most suitable for use with children with NF1. Recently, there have been several computerized measures of attention and executive abilities that have become available to researchers and clinicians. This study explored the National Institute of Health Toolbox Flanker, Dimensional Change Card Sort, and List Sort Working Memory; Cogstate Identification; and Conners Kiddie Continuous Performance Test, second edition …

Shaped By The Environment: The Influence Of Childhood Trauma Exposure, Individual Socioeconomic Position, And Neighborhood Disadvantage On Brain Morphology, Elisabeth Kathleen Webb

Theses and Dissertations

The relationship between an individual’s socioeconomic position (SEP) and their overall physical and mental health has been well demonstrated. Far less is known about how area-level factors, such as neighborhood disadvantage, “get under the skin”. Previous research indicates lower SEP and childhood trauma negatively effects brain structure and function. The hippocampus, amygdala, and ventromedial prefrontal cortex (vmPFC) are particularly vulnerable to adversity. The current study investigated how individual SEP, childhood trauma, and neighborhood disadvantage impact these structures. Two-hundred and fifteen individuals were recruited from an Emergency Department in southeastern Wisconsin. Two-weeks post-traumatic injury, participants completed a structural magnetic resonance imaging …
