Collaborative Models Of Care In The Appalachian Region Of Tennessee: Examining Relationships Between Level Of Collaboration, Clinic Characteristics, And Barriers To Collaboration, Jeffrey Ellison

Electronic Theses and Dissertations

Decades of research have shown that there are significant advantages to maintaining close communicative and collaborative relationships between primary care and behavioral health providers. Fiscal, structural, and systemic barriers, however, often restrict the degree to which such interprofessional collaboration can occur. In the present study the authors examined relationships between primary care clinics in the Appalachian region’s characteristics (i.e., clinic type, rurality, and clinic size), barriers (i.e., fiscal, structural, and systemic) reported to using increased collaboration, and the level of collaboration used at a particular clinic.

For the present study 136 surveys were completed by providers working in primary care …

Impulsivity, Venturesomeness, And Pride: Potential Moderators Of The Relationship Between Childhood Trauma, Substance Use, And Physical Aggression, Joshua P. Hatfield

Electronic Theses and Dissertations

Impulsivity, venturesomeness, and pride variables were examined as potential moderators of the associations between childhood trauma and physical aggression, alcohol use and physical aggression, and drug use and physical aggression. Participants (n = 457) were college students recruited from a university in the Southeast. It was hypothesized that childhood trauma, alcohol use, and drug use would be associated with increased scores of physical aggression. In addition, it was hypothesized that impulsivity, venturesomeness, authentic pride, and hubristic pride would moderate these relationships. Linear, multivariate hierarchical regression analyses were used to examine these variables as potential moderators. Hypotheses concerning hubristic pride as …

Utilizing Visual Attention And Inclination To Facilitate Brain-Computer Interface Design In An Amyotrophic Lateral Sclerosis Sample, David B. Ryan

Electronic Theses and Dissertations

Individuals who suffer from amyotrophic lateral sclerosis (ALS) have a loss of motor control and possibly the loss of speech. A brain-computer interface (BCI) provides a means for communication through nonmuscular control. Visual BCIs have shown the highest potential when compared to other modalities; nonetheless, visual attention concepts are largely ignored during the development of BCI paradigms. Additionally, individual performance differences and personal preference are not considered in paradigm development. The traditional method to discover the best paradigm for the individual user is trial and error. Visual attention research and personal preference provide the building blocks and guidelines to develop …

The Phenomenon Of Abstract Cognition Among Scholastic Chess Participants: A Case Study, Brent C. Laws

Electronic Theses and Dissertations

A qualitative investigation was conducted to explore the phenomenon of abstract cognition among a purposive sample of 5 secondary scholastic chess club participants. The case study enabled the researcher to explore the faculties of abstract cognition among students of contrasting skills and abilities in playing chess. The study also allowed for the consideration of potential visual-spatial, logical, academic, social competency and life benefits of chess play. Through analysis of interviews, chess simulations, blindfold chess play, and narration of chess lines and sequences, the investigator was able to extract meaning and code schemata into a holistic understanding of the phenomenon of …

Mental Health Referral In Primary Care: Influence Of A Screening Instrument And A Brief Educational Intervention, Michael T. Miesner

Electronic Theses and Dissertations

Although less than half of all patients with mental disorders seek mental health treatment per se, approximately 80% of all people will visit their primary care physician (PCPs) within a year (Strosahl, 1998). However, it is not well understood how to best handle patients presenting with mental health issues in primary care practices. The purpose of this project was to implement an intervention involving a screening measure for anxiety and mood disorders in a primary care setting to increase the volume of anxiety and mood disorder screening, to increase the accuracy of disorder detection, and to also enhance PCPs patterns …

An Examination Of Risk And Protective Factors For Suicidal Behavior In A Low-Income, Underserved Primary Care Sample, Kristin L. Walker

Electronic Theses and Dissertations

Suicidal behavior, including ideation and attempts, is a significant public health problem. Due to the complexity of suicidal behavior, it is necessary to consider an array of factors that could serve as risk and protective factors. Previous research has shown that deficits in social problemsolving ability are associated with increased risk for suicidal ideation and attempts; conversely, problem solving strengths are associated with reduced risk. This dissertation project, consisting of 3 individual manuscripts, was designed to explore the relationship between social problemsolving ability and suicidal behavior in low-income primary care patients. Furthermore, additional constructs including health related quality of life, …

The Effect Of Romantic Jealousy On Self-Control: An Examination Of Trait Constructs And Sex Differences Based On Survey And Experimental Data, Lyndsay A. Nelson

Electronic Theses and Dissertations

A large body of research has demonstrated that the experience of romantic jealousy is often associated with a variety of negative outcomes. However, evolutionary psychologists have provided evidence that jealousy is an adaptive emotion that can aid with mate retention. Together these lines of research suggest that jealousy may at times work to protect and enhance one’s relationship, whereas in other cases it could lead to harmful consequences. Considering the varying outcomes of jealousy, it is critical that research explore more specifically how this complex state operates and how it affects individuals’ functioning. In the present research I conducted 2 …

Attitudes Toward Suicide, Mental Health, And Help-Seeking Behavior Among African Immigrants: An Ecological Perspective, Sheri A. Nsamenang

Electronic Theses and Dissertations

The population of Africans in the United States is growing, yet little is known about the impact of migration on the attitudes of African immigrants toward suicide, mental health, and helpseeking behavior. Migration entails movement from one cultural environment to another, and the process requires adaptation to the host country. According to Ecological Theory, interactions between the societal structures, values, and beliefs of the host country, cultural values from the country of origin, and individual-level characteristics may affect mental health-related attitudes and behaviors. As such, the current study used mixed methods, administered via online survey, to investigate socio-cultural predictors of …

The Effects Of Working Memory On Brain-Computer Interface Performance, Samantha A. Sprague

Electronic Theses and Dissertations

Amyotrophic lateral sclerosis and other neurodegenerative disorders can cause individuals to lose control of their muscles until they are unable to move or communicate. The development of brain-computer interface (BCI) technology has provided these individuals with an alternative method of communication that does not require muscle movement. Recent research has shown the impact psychological factors have on BCI performance and has highlighted the need for further research. Working memory is one psychological factor that could influence BCI performance. The purpose of the present study is to evaluate the relationship between working memory and brain-computer interface performance. The results indicate that …

The Mediating And Moderating Effects Of Coping Mechanisms Following High School Victimization, Kevin D. Hyatt

Electronic Theses and Dissertations

Victimization from bullying has become a more serious issue as available avenues for bullying have increased and as the media has been alerted to the devastating effects of the phenomenon. Victimization has been linked to increased externalizing and internalizing disorders including depression, anxiety, stress, and at its worst suicide. Research has been focused on the negative outcomes following victimization, with some authors only recently examining the buffering or exacerbating effects of coping mechanisms. Participants (n=642) from a moderately sized southeastern university completed a survey to examine problem-focused and emotion-focused coping as potential moderators and maladaptive coping as a potential mediator …

Explaining Combat Related Posttraumatic Stress Disorder: An Integrated Mental Illness And Military Process Model, Mandi F. Deitz

Electronic Theses and Dissertations

The purpose of the current study was to examine a process model of combat-related and mental-illness related processes that explain increased likelihood of Posttraumatic Stress Disorder (PTSD). This dissertation proposed the development of PTSD may occur due to cultural, social, and self-related pathways associated with veterans’ dual encounters with combat (i.e., severity) and mental illness symptoms. Participants were 195 military veterans recruited from multiple sites and strategies to maximize sample size and representation. Participants were asked to complete several self-administered assessment inventories, including: the Posttraumatic Stress Disorder Checklist-Military, the Trauma Symptom Checklist, the Combat Experiences scale, the Self-Stigma of Mental …

Addressing Self-Reported Depression, Anxiety, And Stress In College Students Via Web-Based Self-Compassionate Journaling, Jessica Rose Williamson

Electronic Theses and Dissertations

Depression, anxiety, and stress in the college undergraduate population have been steadily rising over the past decade. Trait self-compassion has been shown to be significantly and negatively related to perceptions of stress and symptoms of depression and anxiety. Research has indicated that self-compassion inductions are effective in increasing state self-compassion. In general, selfcompassion inductions are designed to be easily self-administered. Current research on Internetbased interventions indicates that self-administered therapeutic techniques are effective in reducing self-reported depression, anxiety, and stress. The goal of the current study was to compare the effects of self-compassionate journaling, narrative journaling, and a true control group …

Health-Related Quality Of Life And Suicidal Behaviors In Primary Care Patients: Conditional Indirect Effects Via Interpersonal Needs And Depressive Symptoms, Catherine Rowe

Electronic Theses and Dissertations

Suicide is a public health problem and complex relationships exist between intrapersonal suicide risk factors and interpersonal risk factors. Health-related quality of life (HRQL) may interact with difficulties with interpersonal relationships and psychopathology. We examined thwarted interpersonal needs and depressive symptoms as potential mediators on the association between HRQL and suicidal behaviors. It was hypothesized that thwarted interpersonal needs would mediate the association between HRQL and suicidal behavior, and that this mediating effect would be dependent on the moderating effect of depressive symptoms. It was hypothesized that thwarted interpersonal needs and then depressive symptoms would sequentially mediate the association between …

Role Of The Ventral Tegmental Area And Ventral Tegmental Area Nicotinic Acetylcholine Receptors In The Incentive Amplifying Effect Of Nicotine, Ashley B. Sheppard

Electronic Theses and Dissertations

Nicotine has multiple behavioral effects as a result of its action in the central nervous system. Nicotine strengthens the behaviors that lead to nicotine administration (primary reinforcement), and this effect of nicotine depends on mesotelencephalic systems of the brain that are critical to goal directed behavior, reward, and reinforcement. Nicotine also serves as a ‘reinforcement enhancer’ – drug administration enhances behaviors that lead to other drug and nondrug reinforcers. Although the reinforcement enhancing effects of nicotine may promote tobacco use in the face of associated negative health outcomes, the neuroanatomical systems that mediate this effect of nicotine have never been …

Prevalence, Types, Risk Factors, And Course Of Intimate Partner Violence In Appalachian Pregnant Women, Tifani Fletcher

Electronic Theses and Dissertations

Intimate partner violence (IPV) during pregnancy can lead to a myriad of poor physical and psychological outcomes for both mother and child. There is a paucity of research examining IPV risk factors for rural pregnant women and on information regarding the course of the specific types of IPV throughout pregnancy. The current project was an investigation of the prevalence of IPV and IPV risk factors for different types of IPV in an Appalachian pregnant sample that contained women from both rural and nonrural locations (Study 1), and was an examination of the occurrence of any IPV and the different types …

Traditional Masculinity & Advertising Image Approval, Danielle W. Kailing, Peggy Cantrell Phd

Undergraduate Honors Theses

This project investigates the relationship between adherence to traditional masculinity and approval of selected advertising images. Because traditional masculinity includes characteristics supportive of aggression and dominance; I hypothesize that an increase in adherence to traditional masculinity will correlate with approval of the violence found in some print advertisements. Participants include 259 men who completed an anonymous, online, survey. Adherence to masculinity is measured using the Male Role Norm Inventory-Revised (MRNI-R) (Levant, et. al, 2007). Each picture is scored on a 5-point Likert Scale. As hypothesized, an increase in total MRNI-R score, is significantly correlated with an increase in the approval …

The Effects Of Environmental Enrichment On Nicotine Sensitization In A Rodent Model Of Schizophrenia, Marjorie A. Schlitt, Elizabeth D. Cummins, Daniel J. Peterson, Russell W. Brown

Undergraduate Honors Theses

Environmental enrichment, for more than fifty years, has shown to increase learning in behaviors and to alter some brain structures (Renner and Rosenzweig). Some brain changes that occur when environmental enrichment is implemented include the following: increases in cortical thickness, especially the occipital cortex, increases in size of neuronal cell bodies, number of dendrites and dendritic spines, increases in astrocyte branching, increases in the number of brain blood capillaries, and increases in mitochondria (an indication of higher metabolic activity) (Stairs and Bard). It has been shown in research studies that rats in the environmental enrichment group are less sensitive to …

Rural Pediatric Primary Care Practice Patterns As A Result Of An On-Site Behavioral Health Consultant: A Retrospective Analysis, Kayla D. Mccarter

Undergraduate Honors Theses

Nationally, it has been estimated that 10 to 21% of children with psychosocial concerns are seen in primary care settings (Jellinek et al., 1999; McInerny, Szilagyi, Childs, Wasserman & Kelleher, 2000; Palermo et al., 2002). Often, however, children go undiagnosed with/treated for psychosocial concerns in pediatric primary care due to lack of physician time and poor referral rates to mental health providers. Evaluations of integrated care models, in which a behavioral health consultant is present in primary care practices, has shown to increase the availability of mental health services (Stancin, Perrin, & Ramirez, 2009). Using extant data from patient records …

Does Nicotine Alter What Is Learned About Non-Drug Incentives?, Tarra L. Baker

Undergraduate Honors Theses

Nicotine is one of the most addictive drugs known to man, yet it has limited reinforcing effects in humans and non-human animals when it is not self-administered in tobacco products. One hypothesis for these paradoxical effects of nicotine is that the effects of the drug in the brain alter acquisition of incentive learning. The hypothesis for this study is that nicotine will increase the value of cues paired with a reward. To test this hypothesis, 26 Sprague Dawley Male rats were randomly assigned to one of three groups Pre-NIC (the critical experimental group), Post-NIC and SAL. Each group received a …

Neuromodulation Therapy Mitigates Heart Failure Induced Hippocampal Damage, Timothy P. Diperi

Undergraduate Honors Theses

Cardiovascular disease (CVD) is the leading cause of death in the United States. Nearly half of the people diagnosed with heart failure (HF) die within 5 years of diagnosis. Brain abnormalities secondary to CVD have been observed in many discrete regions, including the hippocampus. Nearly 25% of patients with CVD also have major depressive disorder (MDD), and hippocampal dysfunction is a characteristic of both diseases. In this study, the hippocampus and an area of the hippocampal formation, the dentate gyrus (DG), were studied in a canine model of HF. Using this canine HF model previously, we have determined that myocardial …

Traumatic Life Events And Symptoms Of Anxiety: Moderating Effects Of Adaptive Versus Maladaptive Coping Strategies, Alishia Foster

Electronic Theses and Dissertations

The experience of trauma is prevalent among young adult college students and is often associated with poor mental health outcomes such as symptoms of anxiety. Not all individuals who have experienced trauma, however, develop anxiety, perhaps due to individual-level adaptive characteristics, such as use of adaptive rather than maladaptive coping strategies. Yet, little research has examined the interrelationships between the experience of trauma, specific types of coping strategies, and subclinical anxiety symptoms. A sample of 915 undergraduate students completed self-report measures of trauma, coping strategies, and anxiety symptoms. We hypothesized that traumatic life events would be associated with anxiety symptoms, …
