Positive Emotions And Favorable Cardiovascular Health: A 20-Year Longitudinal Study, Julia K. Boehm, Ying Chen, Farah Qureshi, Jackie Soo, Peter Umokoro, Rosalba Hernandez, Donald Lloyd-Jones, Laura D. Kubzansky

Psychology Faculty Articles and Research

No studies have examined whether positive emotions lead to favorable cardiovascular health (CVH) early in the lifespan, before cardiovascular disease is diagnosed. Moreover, the direction of the association has not been thoroughly investigated. Among younger adults, we investigated whether baseline positive emotions were associated with better CVH over 20 years. We also considered whether baseline CVH was associated with subsequent positive emotions during the same period.

Participants included 4196 Black and White men and women from the Coronary Artery Risk Development in Young Adults Study. Positive emotions and cardiovascular-related parameters were each assessed in 1990 (this study's baseline), with repeated …

391— Mental Health Supports Readily Available For College Students, Heidi Granville Apr 2020

391— Mental Health Supports Readily Available For College Students, Heidi Granville

GREAT Day Posters

College students who struggle with mental illness need more resources and support services readily available to them while they are in school. This would help them succeed both as students and as maturing adults. Data collected from Penn State conclude that mental health issues are increasing as time goes on, more students are seeking counseling services, and more students have considered suicide. This data serves a purpose that the current public policy is not enough. Ultimately, when schools are ill-equipped to helping students who suffer from mental illnesses, those students cannot reach their maximum potential, and consequently, the suicide rate …


Anxiety In Alzheimer's Disease, Zachary Cooper Apr 2020

Anxiety In Alzheimer's Disease, Zachary Cooper

Senior Honors Theses

Researchers familiar with Alzheimer’s disease have often noted the presence of comorbid anxiety symptomatology. Likewise, the occurrence of anxiety before the development of Alzheimer’s disease has been prevalent enough to warrant attention. This review seeks to elaborate on the pathophysiology behind these two conditions, and to accentuate overlapping aspects that promote a causal relationship between these two pathologies on the macroscopic and cellular levels. Subsequent evidence will show that these pathologies are not independent of each other, and that cellular mechanisms of pathology hint at their interrelatedness. Areas requiring further research that would clarify the relationship between Clinical Anxiety and …


Public Stigma And Self-Stigma Of Depression In College Students, Peyton Lee Apr 2020

Public Stigma And Self-Stigma Of Depression In College Students, Peyton Lee

DNP Projects

A large body of literature portrays the long-term, increased presence of mental illness stigma in college students, a vulnerable population at high risk of victimization. However, literature lacks sufficient research differentiating between the separate forms of mental illness stigma as well as consistent research examining stigma specific to the mental illness of depression in college students. A cross-sectional, web-based survey design was utilized to collect quantitative data from 432 students at a private, four-year university in the southeastern United States. The primary investigator both described the presence of and relationship between levels of perceived public stigma, personal public stigma, and …


Eye-Tracking Guilt Induction, Cassandra Ellison, Jordan Cooper, Wendy M. Rote, Max Owens Apr 2020

Eye-Tracking Guilt Induction, Cassandra Ellison, Jordan Cooper, Wendy M. Rote, Max Owens

USF St. Petersburg campus Student Research Symposium

Previous studies have shown a difference in perceptions of maternal guilt induction when there are variations in the situation of the event and the structure of the maternal guilt inducting statement (Rote, 2017). This research expands on this by examining whether differences in attention to specific words within guilt inductive statements may underly previously observed variations. Using eye-tracking methodology and hypothetical vignettes, this study examined which words college-aged students attended to most within maternal guilt inductive statements. Vignettes varied in the topic over which guilt was induced (e.g., moral transgression vs personal choice), the focus of the mother’s criticism (behavior …


The Impact Of The Illness Label ‘Gout’ On Illness And Treatment Perceptions In Māori (Indigenous New Zealanders), Nicola Dalbeth, Meihana Douglas, Kate Mackrill, Leanne Te Karu, Maria Kleinstäuber, Keith J. Petrie Apr 2020

The Impact Of The Illness Label ‘Gout’ On Illness And Treatment Perceptions In Māori (Indigenous New Zealanders), Nicola Dalbeth, Meihana Douglas, Kate Mackrill, Leanne Te Karu, Maria Kleinstäuber, Keith J. Petrie

Psychology Faculty Publications

Background: Despite contemporary advances in understanding pathogenesis and effective management of gout, beliefs about the disease continue to be focused on gout as a self-inflicted illness. The illness label itself may contribute to inaccurate perceptions of the disease and its management. In Aotearoa/New Zealand, Māori (Indigenous New Zealanders) have high prevalence of severe gout. The aim of this study was to examine the impact of the illness label ‘gout’ on perceptions of the disease and its management for Māori. Methods: Māori supermarket shoppers (n = 172) in rural and urban locations were recruited into a study examining the perceptions about …

How Do Counselors Support Clients During The Coronavirus Pandemic?, Yoon Suh Moh, Katharine Sperandio

Counseling and Behavioral Health Faculty Papers

It is impossible to deny the extraordinary societal impact of the outbreak of the novel coronavirus, severe acute respiratory syndrome 2 (SARS-Cov-2). All of us are bombarded daily with messages and information related to the pandemic. As this virus garners heightened attention from the media, individuals may have difficulty delineating between misinformation and accurate information about the illness.

We are not writing this article to perpetuate increased fear among the counseling community regarding the spread of the novel coronavirus, but rather to:

  • Provide resources helpful for staying informed about the impact of COVID-19, which is a disease caused by SARS-Cov-2 …


The Tipping Point In Psychopathy: Role Of Psychopathic Traits In Trauma Exposure, Sneha M. Gupta Apr 2020

The Tipping Point In Psychopathy: Role Of Psychopathic Traits In Trauma Exposure, Sneha M. Gupta

Student Theses

Though psychopathy has been associated with a socially deviant lifestyle, the idea of “successful” psychopathy has gained increased attention. Previous research has explored whether psychopathic traits play a role in trauma exposure/ PTSD, using clinical and forensic populations. Results from these studies suggest that Factor 1 traits may protect from trauma exposure (Factor 1 Theory) while Factor 2 traits may worsen the impact of trauma through exacerbated exposure to traumatic events. The objective of this study was to explore the relationship between each of Factor 1 traits and Factor 2 traits with trauma exposure and PTSD. In a sample of …

Reproductive Health Needs Among Women In Treatment For Substance Use Disorder, Jaanki Bhakta, Elizabeth Morse, David Phillippi

DNP Projects

Integrated care models for substance use disorder (SUD) and reproductive health care have been proposed as a strategy to increase access to reproductive health care for women in treatment for SUD. This cross-sectional, survey-based study measured how women of childbearing age in residential treatment report their demand for and access to reproductive health care, their pregnancy intention, contraceptive utilization and preference for integrating reproductive health care with their current SUD treatment milieu. Eighty-five percent of the women interviewed (N=108) expressed a desire to prevent pregnancy in the next year, although only one-third (33.6%) were using a form of contraception at …

2019/2020 Lrsp: Ricardo Andres Pimentel, Ricardo Andres Pimentel

Library Research Scholars Program

Decades of constant wars have produced millions of military personnel returning home after their stints protecting their country. Though many of these military members are able to fully reintegrate into society, a significant minority return with psychical and psychological difficulties. Included in this vast list of difficulties is Post Traumatic Stress Disorder (PTSD). This disorder is particularly endemic to military populations, and although numerous treatment modalities are available to veterans with PTSD, they are not all effective for every individual. Thus, numerous grassroots and private organizations have been working to pair veterans with service dogs for the treatment of PTSD. …


Alexithymia Symptoms Are Not Associated With Childhood Trauma Or Crhr1 Rs110402 Genotype, Emily Wiatr, Grace Sullivan, Scott Stoltenberg Apr 2020

Alexithymia Symptoms Are Not Associated With Childhood Trauma Or Crhr1 Rs110402 Genotype, Emily Wiatr, Grace Sullivan, Scott Stoltenberg

Center for Brain, Biology, and Behavior: Faculty Publications

Alexithymia is associated with difficulties in emotional self-regulation, and alexithymia is specifically associated with an absence of emotional experience and cognition of emotion. Past research has indicated a potential association between alexithymia and the CRHR1 gene . Situational factors may also impact the expression of the CRHR1 gene within an individual. Berenbaum (1996) found associations between PTSD/childhood trauma and alexithymia. This study examined these associations using the Online Alexithymia Questionnaire-G2 (OAQ-G2) as well as DNA samples gathered from 657 participants at the University of Nebraska-Lincoln (72% women; 78.6% white; mean age= 20.34; standard deviation of 2.6). It was hypothesized that …


The Sound Of Music: Correlates Of Harmonious Relationships In Stepfamilies, Emily R. Monnik Apr 2020

The Sound Of Music: Correlates Of Harmonious Relationships In Stepfamilies, Emily R. Monnik

Selected Honors Theses

Family structure has always been an integral part of the nurturing of children and adolescents. In the past fifty years, the number of stepfamilies formed after remarriage superseded the number of stepfamilies following the death of a parent. These new stepfamilies contribute to a more challenging adjustment for children and adolescents as they figure out the role the new stepparent plays in their life, in addition to the non-residential biological parent. This study surveyed undergraduate students at a private university in the United States using a positive and negative interaction questionnaire and family harmony measure. The researcher attempted to find …


Towards Wide Implementation Of Dance Therapy In Mental Health, Pin-Wen Chou Apr 2020

Towards Wide Implementation Of Dance Therapy In Mental Health, Pin-Wen Chou

Dissertations and Theses

In recent years, Dance Movement Therapy (DMT) has been increasingly mentioned in the field of mental health counseling. Despite the progress of DMT in terms of studies showing its efficiency for various forms of mental health conditions such as depression and trauma, the implementation of DMT amongst mental health therapists is still not as widespread as other forms of therapies such as verbal and art therapies. In this project, we aim to determine the underlying causes of its low implementation by surveying a set of populations, specifically mental health patients, mental health therapists that do not specialize in dance/movement therapy, …


Prevalence Of Mental Health History Intake By Medical Trainees, Raymond H. Wen, Laura A. Weingartner, Emily J. Noonan Apr 2020

Prevalence Of Mental Health History Intake By Medical Trainees, Raymond H. Wen, Laura A. Weingartner, Emily J. Noonan

Undergraduate Arts and Research Showcase

BACKGROUND:

In the US, 1 in 5 adults experiences a mental illness. Over 9.8 million adults and youths have serious suicidal thoughts, and LGBTQ+ communities experience an even greater burden of mental health disparities. Mental illness is often recognized late by providers, which prevents timely and effective treatment.

METHODS:

We estimated the frequency and response of healthcare trainees asking about mental health using video-recorded standardized patient interviews conducted by third-year medical students (M3s). Standardized patients are trained to give out specific health history information only when prompted by the student. Students had 30 minutes to complete new patient interviews in …

The present study examines the relationship between social functioning and general anxiety in children with ASD compared to typically developing (TD) children. The first objective of this study was to examine group differences in social impairments and anxiety symptoms between children diagnosed with ASD and TD children. …


Recognizing The Need For Mental Health Reform In The Texas Department Of Criminal Justice, Kara Mchorse Apr 2020

Recognizing The Need For Mental Health Reform In The Texas Department Of Criminal Justice, Kara Mchorse

St. Mary's Law Journal

The ways in which mental health care and the criminal justice system interact are in desperate need of reform in Texas. The rate of mental illness in Texas is higher than the current state of mental health care can provide for. While state hospitals were once the primary care facilities of those with mental illness, the Texas Department of Criminal Justice (TDCJ) has taken on that role in the last few decades; and when the criminal justice system becomes entangled with mental health care, it often leads to “unmitigated disaster.” If Texas continues to allow the TDCJ to act as …


Biological And Social Links Between Eating Behavior And Stress Among College Students, Kailyn M. Mutsch Apr 2020

Biological And Social Links Between Eating Behavior And Stress Among College Students, Kailyn M. Mutsch

Honors Thesis

Stress and eating behaviors are known to be correlated in all ages but is primarily associated with young adults. This correlation can be attributed to both biological and social links. In this review, I detail the effects of stress on the brain in a biological manner and the areas of the brain associated with eating behavior. I will also discuss social factors that could contribute to the correlation between stress and eating behavior in college students. Stress is a major factor in optimal digestion and health. A majority of students report experiencing times of stress or feeling overwhelmed throughout their …

Psychology: Faculty Publications

Circadian rhythms are daily oscillations in physiology and behavior that can be assessed by recording body temperature, locomotor activity, or bioluminescent reporters, among other measures. These different types of data can vary greatly in waveform, noise characteristics, typical sampling rate, and length of recording. We developed 2 Shiny apps for exploration of these data, enabling visualization and analysis of circadian parameters such as period and phase. Methods include the discrete wavelet transform, sine fitting, the Lomb-Scargle periodogram, autocorrelation, and maximum entropy spectral analysis, giving a sense of how well each method works on each type of data. The apps also …

Deconstructing Circadian Disruption: Assessing The Contribution Of Reduced Peripheral Oscillator Amplitude On Obesity And Glucose Intolerance In Mice, Vincent Van Der Vinne, Blanca Martin Burgos, Mary E. Harrington, David R. Weaver

Psychology: Faculty Publications

Disturbing the circadian regulation of physiology by disruption of the rhythmic environment is associated with adverse health outcomes but the underlying mechanisms are unknown. Here, the response of central and peripheral circadian clocks to an advance or delay of the light-dark cycle was determined in mice. This identified transient damping of peripheral clocks as a consequence of an advanced light-dark cycle. Similar depression of peripheral rhythm amplitude was observed in mice exposed to repeated phase shifts. To assess the metabolic consequences of such peripheral amplitude depression in isolation, temporally chimeric mice lacking a functional central clock (Vgat-Cre+ Bmal1fl/fl) were housed …
