Relationship Education And Marital Satisfaction In Newlywed Couples: A Propensity Score Analysis., Rebecca J. Cobb, Kieran T. Sullivan Oct 2015

Relationship Education And Marital Satisfaction In Newlywed Couples: A Propensity Score Analysis., Rebecca J. Cobb, Kieran T. Sullivan

Psychology

The purpose of this study was to investigate whether premarital relationship education and characteristics of relationship education in a community sample of newlywed couples predicted marital trajectories over 27 months. Newlywed couples (N = 191) completed measures of marital satisfaction 9 times over 27 months, and prior to marriage they provided information about relationship education and demographic, personal, and relationship risk factors for marital distress. Propensity scores (i.e., the probability of receiving relationship education) were estimated using the marital distress risk factors, and used to derive a matched sample of 72 couples who participated in relationship education and 86 couples …


“Respect The Way I Need To Communicate With You”: Healthcare Experiences Of Adults On The Autism Spectrum, Christina Nicolaidis, Dora Raymaker, Katherine E. Mcdonald, Amelia E.V. Baggs, Sebastian Dern, Steven K. Kapp, Michael Weiner, Cody Boisclair, Elesia Ashkenazy Oct 2015

“Respect The Way I Need To Communicate With You”: Healthcare Experiences Of Adults On The Autism Spectrum, Christina Nicolaidis, Dora Raymaker, Katherine E. Mcdonald, Amelia E.V. Baggs, Sebastian Dern, Steven K. Kapp, Michael Weiner, Cody Boisclair, Elesia Ashkenazy

School of Social Work Faculty Publications and Presentations

Our objective was to obtain an in-depth understanding of autistic adults’ experiences with healthcare and their recommendations for improving care. Our academic-community partnership used a community based participatory research (CBPR) approach to conduct semi-structured, open-ended interviews with 39 autistic adults and 16 people who had experience supporting autistic adults in healthcare settings. Participants identified patient-level, autism-related factors that impact healthcare interactions, including verbal communication skills, sensory sensitivities, challenges with body awareness, slow processing speed, atypical non-verbal communication, and challenges with organization. However, the success of healthcare interactions largely depended on the interplay between patient- and provider-level factors, as well as …


A Neurobiological Pathway That Mediates Stress-Induced Drug Use, Oliver Vranjkovic Oct 2015

A Neurobiological Pathway That Mediates Stress-Induced Drug Use, Oliver Vranjkovic

Dissertations (1934 -)

Cocaine addiction represents a tremendous health and financial burden on our society and the high rate of relapse to cocaine use in abstinent addicts represents a major barrier to effective therapy. Thus, understanding the factors that contribute to relapse and the underlying neurobiological processes is important for guiding the development of treatment for addiction. Stressful life events often trigger drug use in recovering addicts. The contribution of stress to drug use is problematic due to the unpredictable and often uncontrollable nature of stress. A growing literature indicates that norepinephrine and corticotropin releasing factor (CRF) in the brain play key roles …


Developmental Coordination Disorder: The Relationship Between Gait And Attention With Possible Implications For Early Identification And Intervention, Yocheved Bensinger-Brody Sep 2015

Developmental Coordination Disorder: The Relationship Between Gait And Attention With Possible Implications For Early Identification And Intervention, Yocheved Bensinger-Brody

Dissertations, Theses, and Capstone Projects

The aim of this research was to evaluate how increased levels of challenge to attentional capacity would affect the motor planning and coordination in the gait of children at risk of Developmental Coordination Disorder (DCD) across developmental ages. The study incorporated a dual task paradigm requiring both motor and attention performance, with the primary hypothesis that children who are at risk of DCD across different ages (3- to 8 yrs.-of-age) would demonstrate an alteration in their motor strategies if they were simultaneously engaging in an attention task. A secondary hypothesis of this study was that there is an underlying deficit …


The Effects Of Parent-Adolescent Communication And Parenting Style On The Physical Activity And Dietary Behaviors Of Latino Adolescents, Dianna Mary Boone Sep 2015

The Effects Of Parent-Adolescent Communication And Parenting Style On The Physical Activity And Dietary Behaviors Of Latino Adolescents, Dianna Mary Boone

USF Tampa Graduate Theses and Dissertations

The obesity epidemic among children and adolescents has been growing rapidly over the past 10 years, particularly in Latino children. Multiple researchers have found support for positive associations between parent-child communication and healthy nutrition and exercise behaviors. The present study examined the relations between parent-adolescent communication and parenting style and the dietary and exercise behaviors of Latino adolescents. The study included 79 adolescents between the ages of 13 and 18 years and their parents (100% are Latino). Correlation and hierarchical regression analyses were conducted to determine which parenting style and communication variables are significantly associated with adolescents’ dietary and physical …


Finding The Engram., Sheena A Josselyn, Stefan Köhler, Paul W Frankland Sep 2015

Finding The Engram., Sheena A Josselyn, Stefan Köhler, Paul W Frankland

Brain and Mind Institute Researchers' Publications

Many attempts have been made to localize the physical trace of a memory, or engram, in the brain. However, until recently, engrams have remained largely elusive. In this Review, we develop four defining criteria that enable us to critically assess the recent progress that has been made towards finding the engram. Recent 'capture' studies use novel approaches to tag populations of neurons that are active during memory encoding, thereby allowing these engram-associated neurons to be manipulated at later times. We propose that findings from these capture studies represent considerable progress in allowing us to observe, erase and express the engram.


Development Of A Technology-Based Behavioral Vaccine To Prevent Adolescent Depression: A Health System Integration Model, Benjamin W. Van Voorhees, Tracy Gladstone, Stephanie Cordel, Monika Marko-Holguin, William Beardslee, Sachiko Kuwabara, Mark Allan Kaplan, Joshua Fogel, Anne Diehl, Chris Hansen, Carl Bell Sep 2015

Development Of A Technology-Based Behavioral Vaccine To Prevent Adolescent Depression: A Health System Integration Model, Benjamin W. Van Voorhees, Tracy Gladstone, Stephanie Cordel, Monika Marko-Holguin, William Beardslee, Sachiko Kuwabara, Mark Allan Kaplan, Joshua Fogel, Anne Diehl, Chris Hansen, Carl Bell

Publications and Research

Efforts to prevent depression have become a key health system priority. Currently, there is a high prevalence of depression among adolescents, and treatment has become costly due to the recurrence patterns of the illness, impairment among patients, and the complex factors needed for a treatment to be effective. Primary care may be the optimal location to identify those at risk by offering an Internet-based preventive intervention to reduce costs and improve outcomes. Few practical interventions have been developed. The models for Internet intervention development that have been put forward focus primarily on the Internet component rather than how the program …


Six Principles To Consider When Working With Roman Catholic Clients, Thomas G. Plante Sep 2015

Six Principles To Consider When Working With Roman Catholic Clients, Thomas G. Plante

Psychology

Although the majority of Americans consider themselves to be Christian and affiliated with various Protestant denominations, a quarter of the American population identify themselves as Roman Catholics who are the largest single religious denomination in the country. Yet, surprisingly, fairly little research has been published in the professional psychology literature about working with this very large and diverse group. Psychologists have an ethical responsibility to be aware of and respectful to diversity including diversity based on religious background, affiliation, and perspectives. The purpose of this brief reflection is to offer 6 important principles to keep in mind for professional psychologists …

The project provides guideline recommendations for implementing a comprehensive and developmentally appropriate AYA oncology program at Loma Linda University.


Music Listening As Therapy, David M. Rosenblatt Sep 2015

Music Listening As Therapy, David M. Rosenblatt

Loma Linda University Electronic Theses, Dissertations & Projects

Music is a universal phenomenon and is a real, physical thing. It is processed in neural circuits that overlap with language circuits, and it exerts cognitive, emotional, and physiological effects on humans. Many of those effects are therapeutic, such as reduced symptoms of physical and mental ailments. Music is the result of the elements rhythm, melody, harmony, timbre, dynamics, and form. Rhythm is the focus of pop music, and melody is the focus of classical music. The mind perceives and organizes music in learned, consistent ways in order to generate predictions and extract meaning. There are perceptual laws and information …


Indicators Of Ambiguous Loss In Families With Traumatic Brain Injured Members, Mynda Ohs Sep 2015

Indicators Of Ambiguous Loss In Families With Traumatic Brain Injured Members, Mynda Ohs

Loma Linda University Electronic Theses, Dissertations & Projects

People who have encountered medical traumas can experience significant changes in their lives. As a result, the family members become caregivers and experience increased stress and ambiguous losses (AL). These losses are often unacknowledged even by the family and cause significant distress. It is important that the family acknowledge these losses and allow themselves time to grieve and adapt to the changes in their lives. While it is widely known that caregivers experience this stress, and programs exist to help support these families, there is less known about the effectiveness of these programs. This study has been designed to explore …


Mental Health Screening Of Veterans Diagnosed With Cancer: Analyzing Psychological Distress And Attitudes Towards Seeking Professional Psychological Help, Jessica Jean Baptiste Aug 2015

Mental Health Screening Of Veterans Diagnosed With Cancer: Analyzing Psychological Distress And Attitudes Towards Seeking Professional Psychological Help, Jessica Jean Baptiste

Seton Hall University Dissertations and Theses (ETDs)

Studies analyzing mental health care utilization in veterans with a co-occurrence of a medical and psychological diagnosis are still underrepresented in the literature. The primary purpose of this study is to examine psychological screening methods of veterans diagnosed with cancer and determining when these veterans are more likely to endorse psychological symptoms. This information can contribute to the discussion of effective ways of integrating mental health screening in specialty care settings. A correlational, causal-comparative research design is employed to answer the study research questions and hypotheses. The participants include Vietnam, Korean, and World War II veterans seeking oncology services at …


Clinical Psychology Students’ Perceived Training In Working With Transgender Clients: An Exploratory Study, Vanessa Zimmerman Aug 2015

Clinical Psychology Students’ Perceived Training In Working With Transgender Clients: An Exploratory Study, Vanessa Zimmerman

Graduate School of Professional Psychology: Doctoral Papers and Masters Projects

Literature on appropriate psychological care for the transgender population has been sparse (American Psychological Association [APA], 2009; Carroll, Gilroy, & Ryan, 2002; Israel, Gorcheva, Walther, Sulzner, & Cohen, 2008; Korell & Lorah, 2007; Maguen, Shipherd, Harris, & Welch, 2007; Walker & Prince, 2010). Historically, the focus of research has been on medical care for transgender individuals, and this literature has tended to pathologize the population (APA, 2009). More recently, individuals who identify as transgender have been included under the umbrella of lesbian, gay, bisexual, and transgender (LGBT) studies, where their unique needs are often overlooked or ignored (APA, 2009; Carroll …


Living With Dignity: A Pilot Study Implementing Dignity Therapy With Allogeneic Blood Or Marrow Transplant Recipients, Emily Newman Aug 2015

Living With Dignity: A Pilot Study Implementing Dignity Therapy With Allogeneic Blood Or Marrow Transplant Recipients, Emily Newman

Graduate School of Professional Psychology: Doctoral Papers and Masters Projects

Dignity Therapy is a relatively novel therapeutic intervention designed to address psychosocial and existential distress among those facing life threatening circumstances. This narrative psychotherapy approach invites patients to reflect and speak about issues that are most important to them and hopes to elicit feelings of purposefulness and autonomy, characteristics that are typically waning when nearing end of life. Dignity Therapy consists of a ten question semi-structured interview designed to integrate themes of accomplishments and sources of pride, things that may feel unsaid, and/or particular lessons or wisdom that the patient hopes to pass on to loved ones. The interview is …


Apples And Oranges: An Argument For Psychopathy As A Formal Diagnosis, Katherine K. Mcmann Aug 2015

Apples And Oranges: An Argument For Psychopathy As A Formal Diagnosis, Katherine K. Mcmann

Graduate School of Professional Psychology: Doctoral Papers and Masters Projects

When one thinks of the psychopath, an image of one of the notorious serial killers of the 1980s generally pops in their head- Ted Bundy, Jeffrey Dahmer, or the Green River Killer. While still rare, psychopaths encompass much more than just serial killers, and they have a unique presentation that lies outside the confines of any current diagnosis. Characteristics such as lack of empathy, impulsivity, grandiosity, and poor behavioral controls are included in various personality disorders. The Narcissist will show lack of empathy and grandiosity while the Borderline will have poor behavioral controls and impulsivity, for example. However, the construct …


Visual Hallucinations Differential Diagnosis Annotated Decision Tree, Shelly D. Davis Aug 2015

Visual Hallucinations Differential Diagnosis Annotated Decision Tree, Shelly D. Davis

Graduate School of Professional Psychology: Doctoral Papers and Masters Projects

Differential diagnosis of the etiology of visual hallucinations is challenging. Although visual hallucinations can be symptomatic of psychiatric disorder, they more commonly indicate neurological or medical disorders, sensory impairment, or substance intoxication or withdrawal. Accurate diagnosis and treatment is crucial given that misdiagnosis and incorrect treatment intervention can have profound consequences. The purpose of this paper is to summarize the most prevalent causes of visual hallucinations, review the DSM-5 hallucination decision tree, and provide an annotated visual hallucination differential diagnosis decision tree.


Therapeutic Assessment In Sport Psychology, Fernando Frias Aug 2015

Therapeutic Assessment In Sport Psychology, Fernando Frias

Graduate School of Professional Psychology: Doctoral Papers and Masters Projects

This paper outlines the history of assessment in sport psychology and provides a summary of controversies and criticisms of psychological testing in athletics that have persisted throughout the development of the field. Such concerns include the use of personality inventories and tests for talent identification, the misuse of tests and related ethical concerns, cultural sensitivity of tests, and debates about the validity and reliability of assessment measures. In spite of these concerns, interest and demand for psychological assessment in sport remains. Therapeutic Assessment, an emerging but not yet well-known model of collaborative psychological assessment, addresses many of these criticisms and …


Integrating Clinical Training & Self-Care: Overview, Analysis & Recommendations For Relieving Stress Among Clinicians In Training, Erich Haezebrouck Aug 2015

Integrating Clinical Training & Self-Care: Overview, Analysis & Recommendations For Relieving Stress Among Clinicians In Training, Erich Haezebrouck

Graduate School of Professional Psychology: Doctoral Papers and Masters Projects

Numerous studies over the past two decades have highlighted the prevalence of stress, mental health disorders and interpersonal problems among psychologists. These statistics parallel those for students currently enrolled in clinical psychology graduate programs where such problems have become even more severe. This results in a significant ethical issue in that clinician competency is negatively impacted by emotional problems. This paper seeks to provide an analysis of current self-care literature. The importance of addressing graduate student self-care is first explored and followed by a literature review on interventions that have been successful in maintaining trainee wellness and competence. Recommendations to …


Best Practices In Team-Based Treatment Termination, Leslie Minna Aug 2015

Best Practices In Team-Based Treatment Termination, Leslie Minna

Graduate School of Professional Psychology: Doctoral Papers and Masters Projects

Termination of psychological treatment is a necessary part of the therapeutic process, but it can pose complex clinical, ethical, legal, logistical, and social challenges. This complexity becomes even more evident in the current era of treatment delivered by a team of healthcare professionals. Appropriate termination will usually involve a team decision and synthesis of the various team members’ recommendations for appropriate follow-up, medications, or transfer of care into an integrated formal document to be communicated to the patient. The healthcare team may also face other considerations such as record keeping and communication responsibilities when the patient (or the patient’s insurer) …


Acceptance And Commitment Therapist Views On The Sacred, Amal Abuzalaf Mull Aug 2015

Acceptance And Commitment Therapist Views On The Sacred, Amal Abuzalaf Mull

Graduate School of Professional Psychology: Doctoral Papers and Masters Projects

Spirituality and/or religion (S/R) continue to be an important topic in mental health treatment, especially regarding their relationship to a psychotherapist’s theoretical orientation and practice with clients. Given the increased relevance of spirituality to third-wave cognitive behavioral therapies, the current study explores the S/R of Acceptance and Commitment Therapy (ACT) psychotherapists and how their S/R is associated to their attitudes and behaviors within mental health and their use of ACT. Online surveys were administered, producing a sample of 97 ACT psychotherapists in the United States. Results indicated low levels of religiosity and high levels of spirituality among ACT psychotherapists in …


Human Trafficking & Commercial Sex Exploitation: Treatment Recommendations For An Invisible Population, Abigail K. Wolfe Aug 2015

Human Trafficking & Commercial Sex Exploitation: Treatment Recommendations For An Invisible Population, Abigail K. Wolfe

Graduate School of Professional Psychology: Doctoral Papers and Masters Projects

This article addresses the issue of human trafficking, also termed modern slavery, specifically focusing on the treatment of survivors of Commercial Sexual Exploitation (CSE). Treatment recommendations are made based on a trauma-focused, relational model aimed at reinstating psychological well-being in the survivor. This article reviews the literature on three related bodies of research due to the absence of direct psychological literature. Literature on captivity, control and torture, literature on the treatment of refugees and asylum seekers, and literature on sexual abuse treatment for those who have been victimized through the sex trade. Additionally, practical aspects of human trafficking are discussed …


Examining The Relationship Between Bicultural Stress, Mental Well-Being, Perceived Social Support, And Education Among People Of African Descent, Zemed Beraki Berhe Aug 2015

Examining The Relationship Between Bicultural Stress, Mental Well-Being, Perceived Social Support, And Education Among People Of African Descent, Zemed Beraki Berhe

Seton Hall University Dissertations and Theses (ETDs)

Studies investigating the bicultural experiences of people of African descent are significantly underrepresented in the literature. The primary purpose of this exploratory study was to examine the relationship between experiences of bicultural stress and mental well-being. In investigating this relationship, perceived social support and education were examined as protective factors, and its relationship to bicultural stress for this population. With the ultimate goal of this information contributing to the understanding of bicultural processes within this population and the relationship to mental health outcomes. A non-experimental (non-randomized) research design was utilized to examine the study research questions and hypotheses. The participants …


Mistrust: An Exploration Of African Americans' Attitudes And Perspectives Toward Healthcare, Adolfo Gabriel Cuevas Aug 2015

Mistrust: An Exploration Of African Americans' Attitudes And Perspectives Toward Healthcare, Adolfo Gabriel Cuevas

Dissertations and Theses

This dissertation explored mistrust through focus group discussions (study 1), responses to standardized laboratory vignettes (study 2), and survey questionnaires (study 3). In the first study, I found that African American community members (N=60) experienced perceived discrimination, medical mistrust, and poor communication in numerous and interrelated ways. For example, medical mistrust occurred when clinicians did not convey respect to patients, leaving patients to wonder whether their clinician's treatment was discriminatory or not. Based on these findings, I wanted to see whether these experiences of perceived discrimination and mistrust were related to other dimensions of Black experience, such as racial identity. …


Mental Health Clinical Managers And Their Multicultural Leadership Practices, Christie Marie Melonson Aug 2015

Mental Health Clinical Managers And Their Multicultural Leadership Practices, Christie Marie Melonson

Theses & Dissertations

There is a general recognition that the United States has historically failed to provide adequate mental health services to ethnic minorities. The American Counseling Association has mandated multicultural competence of counseling professionals in today’s context of dramatic demographic change. Despite numerous studies on practitioners, organizations, models, and interventions geared toward minorities, disparities in access, usage, and outcomes in still exist. Simultaneously, counseling fields have emphasized leadership development as a key factor in improving services, yet training or research on leadership remains scarce. In response to these conditions, this basic interpretive qualitative study focused on exploring clinical managers’ perceptions of their …


A Brief Overview Of Amblyaudia, Raelynn Lamminen, Daniel Houlihan Aug 2015

A Brief Overview Of Amblyaudia, Raelynn Lamminen, Daniel Houlihan

Psychology Department Publications

Amblyaudia, a recent subcategory of auditory processing disorder, is characterized by asymmetrical auditory processing of an individual’s ears. Amblyaudia can result in speech comprehension difficulties, reading difficulties, information processing deficits, and inattention. These difficulties can be mistakenly attributed to Attention Deficit Hyperactivity Disorder (ADHD), Specific Learning Disorders (SLD), depression, anxiety disorders, and communication disorders. Unfortunately, traditional hearing tests do not place the two ears in competition and cannot detect asymmetry. Therefore, students who exhibit these difficulties and have normal performance on traditional hearing tests should be also evaluated for amblyaudia with dichotic listening tests. Amblyaudia can be addressed through dichotic …

Soldiers Returning From Deployment: A Qualitative Study Regarding Exposure, Coping, And Reintegration, Lisa A. Brenner, Lisa M. Betthauser, Nazanin Bahraini, Jaimie L. Lusk, Heidi Terrio, Ann I. Scher, Karen A. Schwab

Graduate School of Professional Psychology: Student Scholarship

Purpose/Objective: The purpose of this study was to qualitatively explore exposure to deployment-related physical and/or emotional trauma and associated symptoms among Operation Enduring Freedom/Operation Iraqi Freedom (OEF/OIF) soldiers. Interviews also focused on in-theater- and reintegration-related experiences. Research Method/Design: OEF/OIF soldiers (N = 103) participated in semistructured interviews, and a qualitative descriptive methodology was used to analyze the data. Results: Themes were identified regarding (a) common experiences related to emotional and physical traumas and associated symptoms and strategies for coping and making meaning of experiences and (b) how combat and reintegration experiences affected soldiers’ senses of self, relationships with others, …


Implicit And Explicit Contributions To Statistical Learning., Laura J Batterink, Paul J Reber, Helen J Neville, Ken A Paller Aug 2015

Implicit And Explicit Contributions To Statistical Learning., Laura J Batterink, Paul J Reber, Helen J Neville, Ken A Paller

Brain and Mind Institute Researchers' Publications

Statistical learning allows learners to detect regularities in the environment and appears to emerge automatically as a consequence of experience. Statistical learning paradigms bear many similarities to those of artificial grammar learning and other types of implicit learning. However, whether learning effects in statistical learning tasks are driven by implicit knowledge has not been thoroughly examined. The present study addressed this gap by examining the role of implicit and explicit knowledge within the context of a typical auditory statistical learning paradigm. Learners were exposed to a continuous stream of repeating nonsense words. Learning was tested (a) directly via a forced-choice …


Tract-Based Spatial Statistics In Preterm-Born Neonates Predicts Cognitive And Motor Outcomes At 18 Months., E G Duerden, J Foong, V Chau, H Branson, K J Poskitt, R E Grunau, A Synnes, J G Zwicker, S P Miller Aug 2015

Tract-Based Spatial Statistics In Preterm-Born Neonates Predicts Cognitive And Motor Outcomes At 18 Months., E G Duerden, J Foong, V Chau, H Branson, K J Poskitt, R E Grunau, A Synnes, J G Zwicker, S P Miller

Brain and Mind Institute Researchers' Publications

BACKGROUND AND PURPOSE: Adverse neurodevelopmental outcome is common in children born preterm. Early sensitive predictors of neurodevelopmental outcome such as MR imaging are needed. Tract-based spatial statistics, a diffusion MR imaging analysis method, performed at term-equivalent age (40 weeks) is a promising predictor of neurodevelopmental outcomes in children born very preterm. We sought to determine the association of tract-based spatial statistics findings before term-equivalent age with neurodevelopmental outcome at 18-months corrected age.

MATERIALS AND METHODS: Of 180 neonates (born at 24-32-weeks' gestation) enrolled, 153 had DTI acquired early at 32 weeks' postmenstrual age and 105 had DTI acquired later at …


Transient Visual Responses Reset The Phase Of Low-Frequency Oscillations In The Skeletomotor Periphery., Daniel K Wood, Chao Gu, Brian D Corneil, Paul L Gribble, Melvyn A Goodale Aug 2015

Transient Visual Responses Reset The Phase Of Low-Frequency Oscillations In The Skeletomotor Periphery., Daniel K Wood, Chao Gu, Brian D Corneil, Paul L Gribble, Melvyn A Goodale

Brain and Mind Institute Researchers' Publications

We recorded muscle activity from an upper limb muscle while human subjects reached towards peripheral targets. We tested the hypothesis that the transient visual response sweeps not only through the central nervous system, but also through the peripheral nervous system. Like the transient visual response in the central nervous system, stimulus-locked muscle responses (< 100 ms) were sensitive to stimulus contrast, and were temporally and spatially dissociable from voluntary orienting activity. Also, the arrival of visual responses reduced the variability of muscle activity by resetting the phase of ongoing low-frequency oscillations. This latter finding critically extends the emerging evidence that the feedforward visual sweep reduces neural variability via phase resetting. We conclude that, when sensory information is relevant to a particular effector, detailed information about the sensorimotor transformation, even from the earliest stages, is found in the peripheral nervous system.


Do Stress Levels Differ Between First Semester Nursing Student Early In The Semester Vs. The End Of The Semester?, Alissy Heisey Aug 2015

Do Stress Levels Differ Between First Semester Nursing Student Early In The Semester Vs. The End Of The Semester?, Alissy Heisey

Undergraduate Honors Theses

This study intends to determine how stress levels change over time in nursing students in the Baccalaureate program at East Tennessee State University. The instrument utilized for this survey was the Perceived Stress Scale by Mind Garden, Inc. This survey was passed at the beginning of the semester and at the end of the semester. There was no-significant difference found between the two time spots, leading us to conclude that the level of stress perceived by nursing students is a steady factor during their school semester.
