P300 Event-Related Potentials To A Phoneme Discrimination Task Requiring A Motor Response, Kaitlyn Chelsea Turner

Theses and Dissertations

Speech perception typically takes place within the auditory cortex as evidenced by data collected using quantitative electroencephalography (qEEG). The purpose of this study was to determine if motor responses influence speech perception. We examined P300 event-related potentials during oddball stimulus recognition tasks that either required or did not require a motor response. Based on a review of the literature, it was hypothesized that similar areas of the brain would be activated in both the motor response task and the same task without a motor response immediately following the button-push condition. Two syllables, /ba/ and /ga/, were presented to 20 native …

Cost Of Caring: The Effects Of Euthanasia On Animal Shelter Workers, Kim L. Nguyen-Finn

Theses and Dissertations

This mixed-methods study focuses on animal shelter workers, a population that has often been overlooked in research and clinical practice, and the emotional strains of the task of euthanasia. The effects of employment in a kill or no-kill shelter, participation in euthanasia, and number of years employed on mental health issues of substance abuse, anxiety, depression, secondary traumatic stress, and burnout were examined. A three-way MANOVA was run to test the hypothesis that there is a cell effect among the type of shelter employed in, participation in euthanasia, and years of experience on mental health, which was not supported by …

The Influence Of Therapist-Patient Religious/Spiritual Congruence On Satisfaction With Therapy: A Review Of Research, Tammy E. Henderson

Theses and Dissertations

The goal of this review was to examine the relationship between mental health and religion and/or spirituality. Specifically, it was believed that religion and spiritual congruence had a positive influence on satisfaction with therapy. Indeed, the literature reviewed suggests that therapists should be more open to addressing a patient's religious and/or spiritual beliefs as it could lead to more attuned therapeutic sessions. The importance of congruence between patient and therapist is a factor that can impact the therapeutic alliance, based on the literature, this concept appears to hold true for those that are or are not religiously and/or spiritually inclined.

Quantitative Phenotype Analysis To Identify, Validate And Compare Rat Disease Models, Yiqing Zhao

Theses and Dissertations

Introduction

The laboratory rat has been widely used as an animal model in biomedical research. There are many strains exhibiting a wide variety of phenotypes. Capturing these phenotypes in a centralized database provides researchers with an easy method for choosing the appropriate strains for their studies. Current resources such as NBRP and PhysGen provided some preliminary work in rat phenotype databases. However, there are drawbacks in both projects: (1) small number of animals (6 rats) used by NBRP; (2) NBRP project is a one-time effort for each strain; (3) PhysGen web interface only enables queries within a single study – …

Perceptual Proficiency Ratings Of Obstruent Productions In L2 Learners Of English As A Function Of Speech Task Type, Word Position, And Listener Expertise, Rachel Mcpherson Zitting

Theses and Dissertations

Second language (L2) learners of English must learn to produce English phonemes, words, and sentences. These L2 learners make many errors when learning English; they may change the place or manner of articulation, insert vowels, or delete consonants. Obstruent sounds, such as fricatives, affricates, and stops, can be especially difficult for L2 learners. This study analyzed native English speakers’ perception of the quality of obstruents produced by native Mandarin Chinese and Korean speakers. Target words containing obstruents had been produced in three different tasks: in a carrier phrase, in a paragraph, and in a spontaneous speech sample. Obstruents were produced …

Framed Text Messages As A Nutrition Education Intervention, Michael James O'Halloran

Theses and Dissertations

A youth’s college years is a critical period in health behavior formation, during which body mass index (BMI) and other health behaviors such as diet and physical activity are strong predictors of adult health status. Text messaging is prominent in the lives of most college-age adults. Despite this, relatively few studies have investigated the potential of utilizing a text message-based intervention to target fruit and vegetable consumption, a measure for weight management behaviors. Additionally, few studies utilizing a text message-based intervention have utilized a theory specific to the creation of behavior-motivating text messages. The gain-framed health behavior messages of Prospect …

Queer Health Equity And Cervical Cancer: Identifying Social Determinants Of Papanicolaou Test Uptake In A Sample Of Sexual Minority Women And Gender Nonbinary Individuals, Ariella R. Tabaac

Theses and Dissertations

Sexual minority women (SMW) demonstrate lower rates of cervical cancer screening than heterosexual women. This is concerning as lesbian and bisexual women tend to engage in higher rates of substance-related cancer risk behaviors, unprotected sex, and tend to have higher body mass indices, all of which are risk factors for cancer development. Another major risk factor, screening avoidance, places SMW at increased risk for the development of high grade cervical lesions in the absence of early detection practices, which is likely to impact overall cervical cancer morbidity in this population. The aim of the present study was to utilize the …

Evaluating And Reducing The Effects Of Misclassification In A Sequential Multiple Assignment Randomized Trial (Smart), Jun He

Theses and Dissertations

SMART designs tailor individual treatment by re-randomizing patients to subsequent therapies based on their response to initial treatment. However, the classification of patients being responders/non-responders could be inaccurate and thus lead to inappropriate treatment assignment. In a two-step SMART design, by assuming equal randomization, and equal variances of misclassified patients and correctly classified patients, we evaluated misclassification effects on mean, variance, and type I error/ power of single sequential treatment outcome (SST), dynamic treatment outcome (DTRs), and overall outcome. The results showed that misclassification could introduce bias to estimates of treatment effect in all types of outcome. Though the magnitude …

A Stakeholder Examination Of Gestational Weight Gain Guidelines, Melissa Kwitowski

Theses and Dissertations

Obesity is a significant health concern for women of childbearing age. More than 40% of women have a Body Mass Index (BMI) in the overweight or obese ranges at the time they conceive, posing significant health risks for both mother and child. Excessive weight gain during pregnancy is common and associated with numerous deleterious complications. The Institute of Medicine published gestational weight gain (GWG) guidelines based on prepregnancy BMI. However, more than 50% of women gain in excess of these recommendations. Further, many women report receiving minimal guidance from their healthcare providers regarding weight gain, nutrition, and physical activity during …

How Do Health System Employees With Established Musculoskeletal Complaints Decide On Their Treatment Pathway? A Qualitative Approach, Noor Alshareef

Theses and Dissertations

Purpose: Non-pharmacologic treatment such as physical therapy (PT) are advocated for musculoskeletal pain for decreasing opioid use. Early access to PT has been shown to decrease costs and improve outcomes through direct access via self-referral. Although self-referral to PT is permitted in the majority of U.S states, health insurance coverage has been identified as a barrier preventing some patients with musculoskeletal complaints from using it. There are few studies examining patient factors related to early access to physical therapy via self-referral. The purpose of this study was to identify the factors outside of insurance that influence the choice to access …

Adult Nursing Students’ Perceptions Of Social Presence In Facilitator-Created Subject- Specific Videos In An Online Nursing Course, Jamie Anne Marcus

Theses and Dissertations

The literature established that online instruction consists of cognitive, teaching, and social presence.

Post-video viewing surveys yielded responses to pragmatic and emotional questions. Pragmatic questions were aimed at the visual impact of professor’s delivery of information. Emotional questions gauged the students’ feelings of connectivity with the facilitator. Triangulated …

Shared Genetic And Environmental Influences On Fear, Anxiety, Posttraumatic Stress, And Brain Morphometry, Chelsea Sawyers

Theses and Dissertations

Anxiety disorders (ADs) and stress-related disorders are some of the most common psychiatric disorders in the United States. Like other c0mplex psychiatric illness, genetics and neuroimaging research has focused on understanding their underlying neurobiology. Areas within the fear-network play important roles in threat perception, fear conditioning/learning, cognitive processing, and modulation of fear responses including contextual modulation and extinction and have been implicated in ADs as well as stress disorders such as posttraumatic stress disorder (PTSD). The primary gap in the current search for underlying biological mechanisms is in whether biomarkers associated with disorders share genetic influences with the disorders they …

Association Of Insurance And Provider Type With Patients’ Perceived Cost And Ease Of Access To Healthcare Services Among Medicare Beneficiaries Diagnosed With Diabetes, Metria Harris

Theses and Dissertations

Medicare beneficiaries diagnosed with diabetes are likely to have health complications or episodes associated with diabetes, resulting in higher health care utilization and costs. Andersen’s Health Care Utilization Behavior Model (HCBM) includes predisposing, enabling, and need factors, but it excludes perception. Ajzen’s Theory of Planned Behavior (TPB) shows that perception influences health service use. This study was performed using a real-world model integrating Andersen’s HCBM and Ajzen’s TPB to determine whether there was an association between insurance type (Medicare Part D versus non-Part D) and perceived ease of access or cost among Medicare beneficiaries with diabetes. The second objective was …

Effects Of A 2-Week Exercise Intervention On Heart Rate Variability In Individuals With Low And High Anxiety Sensitivity, Hannah M. Kotarski

Theses and Dissertations

Anxiety Sensitivity (AS), the belief that anxiety-related sensations may have harmful implications, can alter autonomic nervous system (ANS) function. Exercise has previously been shown to reduce AS; however, the effects of an exercise intervention on heart rate variability (HRV), a measure of ANS function, has not been evaluated in individuals with high AS. This study sought to 1) compare resting HRV in individuals with either low (LAS) or high AS (HAS) and 2) evaluate the effects of a 2-week exercise intervention on HRV and AS. Using the Anxiety Sensitivity Index (ASI-3), participants were identified as LAS (n=9; ASI-3=5.89±1.39) or HAS …
