Effects Of Sleep On Intrusive Symptoms And Emotional Reactivity In A Laboratory-Based Film Analog Study, Anna Marie Thi Thanh Nguyen May 2021

Effects Of Sleep On Intrusive Symptoms And Emotional Reactivity In A Laboratory-Based Film Analog Study, Anna Marie Thi Thanh Nguyen

Graduate Theses and Dissertations

Posttraumatic stress disorder (PTSD) is characterized by four symptom clusters. Recently, research highlights the need to focus on the impact of intrusive symptoms as a possible risk factor for the development and maintenance of PTSD. Cognitive and sleep models contribute to further understanding of intrusive symptoms. Recent work also highlights disgust as an emotion closely associated with the emergence of posttraumatic stress symptomology following traumatic events. This study used a film eliciting disgust in order to examine the effects of sleep on the intensity of intrusion symptoms and emotion reactivity. The sample consisted of 49 college students randomly assigned to …


The Impact Of Mindfulness On Healthy Food Choices, Kaylea Hopfer May 2021

The Impact Of Mindfulness On Healthy Food Choices, Kaylea Hopfer

Graduate Theses and Dissertations

The practice of mindfulness has a long history in research, particularly psychological studies. In this paper I examine the effects of a short mindfulness intervention on healthy food purchases. Specifically, I developed an online survey and recruited 634 participants via Prolific between July 24 - July 27, 2020. I randomly assigned participants to either a mindfulness manipulation or a control condition. Following treatment (or control) participants completed a food choice task and various other control. Following the survey, I analyzed data using R version 4.0.2 (2020-06-22) and R-Studio. I estimated three different regression models, ordinary least squares (OLS), Poisson, and …


Barriers To Integrated Primary Care And Specialty Mental Health Services: Perspectives From Latinx And Non-Latinx White Primary Care Patients, Elizabeth A. Anastasia May 2020

Barriers To Integrated Primary Care And Specialty Mental Health Services: Perspectives From Latinx And Non-Latinx White Primary Care Patients, Elizabeth A. Anastasia

Graduate Theses and Dissertations

High need, low access, and rising health care costs reveal the inadequacies of the current mental health system in the U.S. Racial/ethnic minorities, including Latinxs, face substantial disparities in accessing mental health treatment compared with non-Latinx Whites. Integrated primary care (IPC) offers an alternate model for meeting mental health needs by providing care in a way that is accessible to the general population. Though it has been suggested that IPC may reduce health disparities by decreasing barriers to mental health treatment, empirical data relevant to this question are limited. A series of three studies were conducted using a mixed methodology …


An Experimental Test Of The Effects Of Sleep Deprivation On Approach Behavior, Rebecca L. Campbell May 2020

An Experimental Test Of The Effects Of Sleep Deprivation On Approach Behavior, Rebecca L. Campbell

Graduate Theses and Dissertations

Emotion regulation and sleep have been identified as mechanisms that may be involved in the development and maintenance of many mental health disorders. However, there has been little research into the relation between sleep and emotion regulation. To address this gap in knowledge, a novel study was conducted. We hypothesized that sleep deprived individuals would demonstrate less approach behavior toward a negatively valenced stimulus, as well as increased self-reported avoidance, compared to a control group. To test this, a randomized controlled experiment using a behavioral measure of approach and a self-report measure of avoidance was conducted. Fifty-two healthy individuals ages …


The Effects Of Auditory And Olfactory Cues On Visual Attention Toward Food Images Under Acute Stress, Reza Moltaji May 2020

The Effects Of Auditory And Olfactory Cues On Visual Attention Toward Food Images Under Acute Stress, Reza Moltaji

Graduate Theses and Dissertations

Psychological stress has been shown to increase preference for high calorie foods containing high levels of sugar and fat. Since excessive intake of high calorie foods may increase potential risk of obesity and other relevant health issues, relieving psychological stress may help in maintaining a balanced diet and good health status. Although a variety of strategies for relieving psychological stress has been suggested, little attention has been paid to regarding whether such strategies can result in balanced diets. Since music therapy and aromatherapy have proven popular approaches to relieving psychological stress, this thesis aimed at determining whether listening to music …


Effects Of Multivitamin-Mineral Supplementation On Mental Health Among Young Adults, Ya-Hsuan Chang Aug 2019

Effects Of Multivitamin-Mineral Supplementation On Mental Health Among Young Adults, Ya-Hsuan Chang

Graduate Theses and Dissertations

The percentage of young adults who had mental illnesses has increased from 2008 to 2015. However, few existing studies investigating the potential benefits of multivitamin-mineral (MVM) supplementation on mental health focused on young adults (18-24 years of age), whose eating behaviors are often unhealthy. The purpose of this study was to examine the effects of a MVM supplement on mental health in young adults. One hundred and thirty-three college students (Mage=20.59, SD=1.77; 80.15% female) participated in this randomized, double-blind, placebo-controlled trial. Participants consumed either a MVM supplement or a placebo for 30 days. The supplement contained B Vitamins, Vitamin C, …


Alcohol Use, Dietary, And Exercise Behaviors: A Latent Profile Analysis Of Young Adult Lifestyle Behaviors, Ryan Wesley Grant May 2019

Alcohol Use, Dietary, And Exercise Behaviors: A Latent Profile Analysis Of Young Adult Lifestyle Behaviors, Ryan Wesley Grant

Graduate Theses and Dissertations

As individuals enter adulthood, their lifestyles and lifestyle behaviors begin to change drastically. These lifestyle behavior changes in emerging adulthood provide a foundation for future health behaviors that often persist through all of adulthood. The aim of this study was to use Latent profile analyses (LPA) to discover distinct profiles of homogenous groups of young adults based on alcohol, diet, and exercise behaviors. Overall, five distinct profiles for both males and females were identified: Moderates, Unhealthy Eaters, Medium Drinkers, Healthier Eaters and Exercisers, and Heavy Drinkers. Heavy Drinkers and Unhealthy Eaters were the highest risk groups and reported the highest …


Reducing The Risk: Psychological And Technological Approaches For Improving Handwashing Practices In The Foodservice Industry, Jeffrey Allan Clark May 2019

Reducing The Risk: Psychological And Technological Approaches For Improving Handwashing Practices In The Foodservice Industry, Jeffrey Allan Clark

Graduate Theses and Dissertations

As Americans are spending greater portions of their dollar on food consumed outside the home, the foodservice industry plays more of an integral part of daily existence compared to previous generations. Given the numerous annual foodborne illness outbreaks that threaten human lives while undermining confidence in the food supply, food safety is a pertinent issue for industry stakeholders, government regulators, and consumers. Food worker handwashing reduces the risk of foodborne illness transmission, yet compliance with this simple behavior is a complex problem. This dissertation addresses, predominantly, the issue of sub-optimal handwashing practices through applying psychology and technology, including wearable computers …

A Behavioral Test Of Contamination Fear In Excessive Health Anxiety, Robert Edwin Brady May 2012

A Behavioral Test Of Contamination Fear In Excessive Health Anxiety, Robert Edwin Brady

Graduate Theses and Dissertations

Hypochondriasis and health anxiety are characterized by preoccupation with the fear of currently having a serious physical illness. The Diagnostic and Statistical Manual of Mental Disorders conceptualization of hypochondriasis does not include consideration of the fear of acquiring an illness; however, many individuals with severe health anxiety report concern about contamination, suggesting that the current conceptualization of hypochondriasis may be incomplete. The present study utilized behavior approach tasks (BATs) to examine the degree to which contamination fear is present in severe health anxiety. Additionally, perceived vulnerability to disease (PVD) and disgust were tested as potential mechanisms in health anxiety and …
