Understanding Veteran Perceptions About Mental Health And Its Treatment, Quinn Turner Stoddard Jul 2023

Understanding Veteran Perceptions About Mental Health And Its Treatment, Quinn Turner Stoddard

Dissertations and Theses

Mental health illnesses are a growing issue for a large part of the country, and veterans in particular are vulnerable to the numerous negative effects they pose. Despite the high number of people that may benefit from treatment, a variety of issues with trust, stigma, and attitudes may act as barriers to care utilization. In response, this study investigated the perceptions that veterans within the Pacific Northwest hold in regards to mental health treatment as well as their intentions to seek it out should they require it. Using the integrated model of behavioral prediction (IMBP), data was gathered about veterans’ …


Investigating Interpersonal And Community Drivers Of Taenia Solium Prevention To Reduce Acquired Seizure Disorders In Northern Peru: An Analysis Of Social Networks, Social Capital, And Community-Identified Barriers And Facilitators, Angela Gayle Spencer Jun 2023

Investigating Interpersonal And Community Drivers Of Taenia Solium Prevention To Reduce Acquired Seizure Disorders In Northern Peru: An Analysis Of Social Networks, Social Capital, And Community-Identified Barriers And Facilitators, Angela Gayle Spencer

Dissertations and Theses

Background: In Northern Peru and other low- and middle-income countries (LMICs) worldwide, the Taenia solium parasite causes an estimated 30% of acquired epilepsy -- an entirely preventable disease burden. Sanitation development and pork production regulation would reduce infection risk in endemic communities, but large-scale systemic improvements are not likely to occur in the near future. In the meantime, communities can reduce infection risk by adopting protective behaviors. Social networks can provide role modeling and support for health-promoting behaviors, and deliver social capital in the form of trusting relationships, norms of reciprocity, and information exchange in support of T. solium control. …

It also provides perspectives on CDSS adoption in the context of Information Systems and Health Technology. The review helped identify research gaps, objectives, and questions. …


Experiences Of People With Serious Mental Illness Seeking Services At Community Mental Health Centers During The Covid-19 Pandemic, Emily Leickly May 2023

Experiences Of People With Serious Mental Illness Seeking Services At Community Mental Health Centers During The Covid-19 Pandemic, Emily Leickly

Dissertations and Theses

Community mental health centers (CMHCs) have been underfunded and overburdened since Reagan-era disinvestment and the United States' move toward neoliberalism. Rates of mental illness have been rising consistently, particularly in Oregon, as CMHCs face continuing financial pressures and staff retention issues. This was before the COVID-19 pandemic. Today, we are still trying to understand the ongoing pandemic's impact on people with serious mental illnesses (SMI). Most of the studies in this area thus far are quantitative, and first-hand accounts of the pandemic from people with SMI are largely absent. Additionally, research in this area fails to draw on critical alternative …

Health Literacy And People Diagnosed With Mental Illness, Beckie Child Aug 2022

Health Literacy And People Diagnosed With Mental Illness, Beckie Child

Dissertations and Theses

Health literacy is a well-studied concept that has a large literature base. Yet, little is known about health literacy and people diagnosed with mental illnesses, and even less health literacy research speaks to people diagnosed with mental illness. I used a framework and approach of lived experience of psychiatric diagnosis and psychiatric survivor research to conceptualize and inform the study. It explores health literacy with people diagnosed with mental and physical health diagnoses using a small quantitative survey, focus groups, and an individual interview. The findings suggest that health literacy is a dynamic and complex construct that interacts with the …

Treatment Disparities In Emergency Medical Services: The Influence Of Race/Ethnicity, Obesity, And English Proficiency, Jamie Kennel

Dissertations and Theses

Different treatment in healthcare settings provided to different social groups of people may lead to disparities in health, quality of life, and life span. Despite the critical role among healthcare services that Emergency Medical Services (EMS) provides disproportionately for marginalized communities, it remains unclear if and to what extent treatment disparities take place in the pre-hospital setting. Guided by the theoretical frameworks of social worth, aversive racism, and stigma, this study utilizes medical chart data from three different public and private datasets to investigate treatment disparities by Emergency Medical Service providers for racial minority, obese, and limited English proficiency patients. …


The Effects Of Language Proficiency On Narrative Macrostructure In Spanish-English Bilinguals, Jenny Magallon Jun 2022

The Effects Of Language Proficiency On Narrative Macrostructure In Spanish-English Bilinguals, Jenny Magallon

Dissertations and Theses

Bilingual children of the same age may have different narrative skills depending on the quantity and quality of their experiences in the two languages. Thus, children's storytelling skills can vary depending on children's oral proficiency in each language. The present study examined the effects of oral proficiency on story structure in forty 5- to 7-year-old Spanish-English speaking children using Spanish and English samples from story retelling tasks. Language proficiency was measured as continuum of performance using the Spanish-English Language Proficiency Scale (SELPS; Smyk et al., 2013). To estimate the effects of Spanish and English proficiency on story structure, linear regressions …

Fortunate People In A Fortunate Land: Dwelling And Residential Alienation In Santa Monica's Rent-Controlled Housing, Lauren E.M. Everett

Dissertations and Theses

The importance of safe and stable housing for individual and community wellbeing is widely acknowledged. However, for the one third of Americans who rent their homes, housing-related stress and precarity (residential alienation) may undermine stability and a sense of home. Rent control is perhaps the most well-known tenant protection policy in the United States, but it remains highly controversial and its efficacy has been debated for decades. This research is the first academic inquiry to examine the policy through the experience of residents of rent-controlled housing. In academic discourse dominated by quantitative inquiry from the discipline of economics, this study …


Antipsychotic Medication Administration In Oregon Assisted Living/Residential Care Settings: Analyzing An Action Situation, Sarah Dys Dec 2021

Antipsychotic Medication Administration In Oregon Assisted Living/Residential Care Settings: Analyzing An Action Situation, Sarah Dys

Dissertations and Theses

Antipsychotic medication use (APU) in assisted living and residential care (AL/RC) settings is an under-studied and controversial health policy issue. APU in older adults with dementia is associated with an increased risk of falls, hospitalizations, and early mortality. I operationalize the Institutional Analysis and Development Framework using a situational analysis approach, an extension of grounded theory methods, to explore the APU in Oregon AL/RC settings. Regulatory deficiency citations, Oregon AL/RC population data, and semi-structured interviews suggest that staff role clarity, organizational characteristics, and perceived agency influence decision-making around APU. AL/RC providers and caregivers are forced to simultaneously balance and prioritize …


The Longitudinal Effects Of A Family And Sleep Supportive Intervention On Service Member Anger And Resilience, Shalene Joyce Allen Oct 2021

The Longitudinal Effects Of A Family And Sleep Supportive Intervention On Service Member Anger And Resilience, Shalene Joyce Allen

Dissertations and Theses

The vast majority of workplace intervention research on employee anger and resilience primarily focuses on individual-level strategies for mitigating employee anger and resilience outcomes in the workplace, with no studies having examined these outcomes with tangible occupational health interventions utilizing organizational-level techniques. Thus, the current study extends the literature on how to provide improvements in employee anger and resilience using higher system and organizational change mechanisms by providing evidence-based support for the effectiveness of a Total Worker Health® intervention, referred to as the Family and Sleep Supportive Intervention Training (FaSST). This approach employs both health protection and health promotion strategies …


Affecting Absenteeism Through School-Based Health Services Delivery: A Configurational Comparative Methods Study Of Oregon's Public Secondary Schools, Kelly Elizabeth Coates Jul 2021

Affecting Absenteeism Through School-Based Health Services Delivery: A Configurational Comparative Methods Study Of Oregon's Public Secondary Schools, Kelly Elizabeth Coates

Dissertations and Theses

A student's ability to attend school regularly can be profoundly affected by poor health-related behaviors, illnesses, and chronic diseases that are left unaddressed and unattended. The delivery of health services in the school environment is uniquely positioned to interrupt the effects these health barriers to learning (HBLs) can have on subsequent diminished educational and health outcomes. The literature widely acknowledges the intersectionality between health and education, but no comprehensive overview exists of how different structures and processes within a school work (or do not work) together to lead to higher or lower student absenteeism. This research sought to fill that …


Ancillary Data For Refining Computer Adaptive Algorithms For The Assessment Of Anomia, Emily Kathryn Tudorache Jul 2021

Ancillary Data For Refining Computer Adaptive Algorithms For The Assessment Of Anomia, Emily Kathryn Tudorache

Dissertations and Theses

Computer adaptive testing formats, based in item response theory (IRT), are becoming an increasingly popular approach to testing in healthcare because they offer numerous psychometric and practical advantages to assessment when compared to static tests that rely on classical test theory. Fergadiotis and colleagues (2015) have developed computer adaptive versions of the Philadelphia Naming Test (PNT) short-forms, which have demonstrated acceptable precision and standard error of measurement when compared to the static short-forms and original full-length assessment. This study sought to use synthetic data simulations using the catIrt R package (Nydik, 2014) to investigate possible advantages of the use of …

Returning To Rejection: Outcomes And Boundary Conditions Of Mental Illness Stereotypes, Stefanie Fox Mar 2021

Returning To Rejection: Outcomes And Boundary Conditions Of Mental Illness Stereotypes, Stefanie Fox

Dissertations and Theses

Mental illness is a common condition in the United States, with over 20% of working age adults managing a mental illness condition in a given year. Disclosure of mental illness is often required for workers to take advantage of employer-provided resources (e.g., accommodations), yet use of resources is exceedingly low (less than 10%). Negative stigma-related outcomes are a top reason for which individuals delay the use of resources. Using an experimental design in an online data collection of 242 participants over two time points, the current study builds on existing organizational diversity literature to examine the stereotypes associated with mental …

The program reveals how the state, through the public health service, partners with scholars, researchers, and community-based organizations to produce, reproduce and perpetuate …


Aligning Food Environments With Institutional Values: A Mixed Methods Study Of Oregon Health Care Organizations, Elizaveta Walker Dec 2020

Aligning Food Environments With Institutional Values: A Mixed Methods Study Of Oregon Health Care Organizations, Elizaveta Walker

Dissertations and Theses

A major driver of the obesity epidemic is obesogenic food environments, characterized by nutrient-poor and energy-dense foods that saturate the collective physical, economic and sociocultural conditions that influence nutritional status. Food environments in organizations such as hospitals and public health agencies warrant special consideration given their health-focused mission. Improving food environments within health care settings has been highlighted by the Centers for Disease Control and Prevention (CDC) as one of seven key strategies to prevent obesity. However, most of the refereed literature examining healthy food environment policies (HFEPs) within hospitals focuses on the inpatient dietary environment, leaving a paucity of …


Smoking Behaviors In Patients Offered Lung Cancer Screening, Sara Elizabeth Golden Nov 2020

Smoking Behaviors In Patients Offered Lung Cancer Screening, Sara Elizabeth Golden

Dissertations and Theses

In the United States, smoking causes preventable diseases, including lung cancer, which is the leading cause of cancer deaths. Improving smoking cessation rates is important to decrease lung cancer deaths. Health care visits with a discussion about lung cancer screening (LCS) may help in increasing prevalence of smoking cessation. Importantly, insurers now require clinicians to have a shared decision-making discussion with patients that includes discussion of smoking abstinence before they can receive an LCS scan (i.e., a low-dose computed tomography scan). This discussion may represent a unique opportunity to encourage smoking cessation since it may prompt positive smoking behavior change. …


Inclusion For Speech-Language Pathology Minority Graduate Students, Teresa Michelle Roberts Nov 2020

Inclusion For Speech-Language Pathology Minority Graduate Students, Teresa Michelle Roberts

Dissertations and Theses

Speech-language pathologists provide assessment and intervention for communication, cognition, and swallowing disorders for individuals across the lifespan in educational, medical, and private practice settings. The demographics of professionals in the field do not reflect those of the general public in regard to race and ethnicity, gender, socioeconomic status, LGBTQ+, and disability. Lack of representation of minorities limits research, policy, and services designed to serve diverse populations. Although initiatives have sought to address lack of diversity of speech-language pathologists, limited research on the graduate training experience for minority students is available. Since a master's degree is required to become a speech-language …

The current study examined implicit sound- and visual-meaning-mappings of children with and without Developmental Language Disorder (DLD).

One child with DLD and 29 children with typical language development (TLD) were included in the study, based on results from a hearing screening and standardized assessments of cognitive and expressive language skills. Participants completed two computer-based experiments, which were designed to investigate: 1) sound discrimination (pitch and duration), implicit mapping of sound stimuli to objects; 2) visual discrimination, implicit mapping of visual stimuli to objects.

The current study showed that children with TLD who implicitly learned pitch categories showed better mapping of …


The Role Of Strategic Governance In Reducing Infant Mortality Under Crisis Conditions, Lynn Christine Finley Jun 2020

The Role Of Strategic Governance In Reducing Infant Mortality Under Crisis Conditions, Lynn Christine Finley

Dissertations and Theses

The infant mortality rate (IMR) in some developing countries has decreased faster than the global average even though these countries lack strong economic growth, good governance, and democracy (often acknowledged precursors to improved health outcomes). What accounts for the improvement of the IMR in the absence of these traditional pathways to health gains? Some scholars suggest that the concept of "strategic governance" might help direct attention to intermediary factors that reduce neonatal deaths in countries that experience crisis conditions. The main objective of this dissertation is to investigate the set of governance practices that have reduced IMR in two such …
