Improv To Improve Interprofessional Communication, Team Building, Patient Safety, And Patient Satisfaction, Candace A. Campbell May 2014

Improv To Improve Interprofessional Communication, Team Building, Patient Safety, And Patient Satisfaction, Candace A. Campbell

Doctor of Nursing Practice (DNP) Projects

The purpose of this process improvement project was to implement a test of change within a healthcare team utilizing applied improvisational exercises (AIEs), and to lay the groundwork for more effective inter- and intra-professional communication.

Literature review: AIEs have been shown to facilitate individual participant communication strengths through a process of un-learning certain common behavioral habits, and learning new habits that assist in creating and expanding closed-loop communication. Such un-learning and learning enriches the participant’s awareness of the environment and encourages participant adaptability through positive group interactions.

Method: An all-day AIE seminar/workshop was conducted with members of two healthcare teams …


The Effect Of Patient Education On Anxiety Levels In Patients Receiving Chemotherapy For The First Time, Sarah Garcia May 2014

The Effect Of Patient Education On Anxiety Levels In Patients Receiving Chemotherapy For The First Time, Sarah Garcia

Evidence-Based Practice Project Reports

Cancer affects approximately 1.5 million people every year throughout the United States.Comprehensive care that includes psychosocial aspects is important to help patients effectively adapt to their diagnosis and treatment plan. Improper prevention and management of anxiety can lead to poor psychosocial outcomes, dissatisfaction with care, and decreased adherence to treatment. Current evidence suggests that education is effective at helping reduce anxiety in patients receiving chemotherapy for the first time. The purpose of this evidenced based practice project was to determine if nurse-led patient education regarding chemotherapy side effects, side-effect management, and orientation to the infusion center was effective at decreasing …


The Use Of Stress Reduction Techniques In Nursing Education, Jennifer S. Bauer May 2014

The Use Of Stress Reduction Techniques In Nursing Education, Jennifer S. Bauer

Evidence-Based Practice Project Reports

Stress is a complex phenomenon that has significant effects on students which may disturb their physiological, psychological, and spiritual health and well-being. Nursing students have been identified to be at high risk for stress during their education. Stress can arise from new clinical experiences, academic load, and personal stressors (Jones & Johnston, 2006). This increase in stress can lead to the student’s inability to assimilate and learn within the classroom and clinical settings. A review of the literature provided evidence that reported a positive relationship between guided imagery and a decrease in stress and anxiety. This evidence-based practice (EBP) project …


Physical Activity And Nutritional Behavior Of Overweight College Students Trying To Lose Weight 2014, Santino Vallejos M.S. May 2014

Physical Activity And Nutritional Behavior Of Overweight College Students Trying To Lose Weight 2014, Santino Vallejos M.S.

Master's Theses

Although there are numerous benefits to increased physical activity and proper dietary behaviors, the decreased participation in physical activity and poor dietary behaviors has emerged as a significant problem within the college student population. The focus of this research study was to identify the relationship between physical activity and dietary behavior to weight loss behaviors within an undergraduate student sample of a small, comprehensive northeastern university. College-aged students (age range: 17 to 27 years old) completed the American College Health Association’s (ACHA) National College Health Assessment II (NCHA) during the years 2009 and 2012. According to the results, there were …


Do Culture And Biological Sex Influence People Who Engage In Non-Suicidal Self-Injury?, Rachel Berger May 2014

Do Culture And Biological Sex Influence People Who Engage In Non-Suicidal Self-Injury?, Rachel Berger

Graduate Theses

Non-Suicidal Self-Injury (NSSI) refers to behaviors in which a person intentionally harms and causes tissue damage to oneself, without the desire to end his or her life. There have been contradictory findings with regard to differences in NSSI by biological sex and culture. In this study, I sought to examine if adults with independent cultural self- construals would report more occurrences of NSSI in comparison to those with interdependent cultural self-construals. Furthermore, I was interested in whether females would report more instances of NSSI in comparison to males in independent based cultures, and I examined whether the methods and reasons …


"Can’T Touch This": Empowering Children With Severe Food Allergy In The Residential Camp Setting 2014, Alexsandra Dubin May 2014

"Can’T Touch This": Empowering Children With Severe Food Allergy In The Residential Camp Setting 2014, Alexsandra Dubin

Master's Theses

The purpose of this project was to create an empowerment program for children with severe food allergy (SFA) in a residential camp setting. Despite recent advancements in research, there is no cure for SFA, thus there is a need for programs to help children manage their allergies and cope with the ramifications of their condition. Quality of life is a major concern for children with SFA, as the constant fear of exposure to an allergen can lead to high levels of anxiety. This is particularly noteworthy because, barring exposure to an allergen, these children are otherwise healthy and symptom free. …


Haptic And Exoskeleton Devices For Neurorehabilitation Of Upper Limb Paralysis: A State Of Art And A Night Landing Task, Samantha Renee Wagner May 2014

Haptic And Exoskeleton Devices For Neurorehabilitation Of Upper Limb Paralysis: A State Of Art And A Night Landing Task, Samantha Renee Wagner

All NMU Master's Theses

Rehabilitation is an important training phase for those suffering from upper limb paralysis as a result of brain injury. When successfully completed, the re-trained limb should be able to successfully complete daily life activities. An alternative to traditional therapy is the usage of effective rehabilitation by using haptic devices in a virtual environment. The type of haptic device and task are crucial for the success of the therapy training sessions. After presenting a state-of-art literature review of several haptic devices that has been used in research and clinical facilities, we thought to use the black hole illusion (BHI), a night …


Rural Pediatric Primary Care Practice Patterns As A Result Of An On-Site Behavioral Health Consultant: A Retrospective Analysis, Kayla D. Mccarter May 2014

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 …


Neuromodulation Therapy Mitigates Heart Failure Induced Hippocampal Damage, Timothy P. Diperi May 2014

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 …


The Reversal Effects Of Curcumin, An Herbal Remedy, On The Impairments Induced By Vmat-2 Inhibitor Tetrabenazine, Emily Qian, Samantha E. Yohn May 2014

The Reversal Effects Of Curcumin, An Herbal Remedy, On The Impairments Induced By Vmat-2 Inhibitor Tetrabenazine, Emily Qian, Samantha E. Yohn

Honors Scholar Theses

Substantial evidence has shown that dopamine (DA), particularly in the nucleus accumbens (NAc), is involved in behavioral activation and effort-related processes, such as overcoming work related response costs. Interference with accumbens DA transmission through administration of the vesicular monoamine transportor-2 (VMAT-2) inhibitor tetrabenazine (TBZ) produces an alteration of response allocation in the concurrent FR5/chow choice procedure, biasing animals toward the lower effort alternative. It has been suggested that these drug-induced shifts in effort-related choice behavior seen in rodents are analogous to symptoms such as psychomotor retardation, anergia, and fatigue, which can be observed in people with depression and other related …


Evaluation Of Video Modeling To Teach Children Diagnosed With Asd To Avoid Poison Hazards, Shannon Eileen King May 2014

Evaluation Of Video Modeling To Teach Children Diagnosed With Asd To Avoid Poison Hazards, Shannon Eileen King

USF Tampa Graduate Theses and Dissertations

Accidental poisonings are one of the leading safety threats for young children, so it is important to teach children to avoid ingesting poisonous substances. Research has shown that behavioral skills training (BST) and in situ training (IST) are effective in teaching children safety skills to prevent gun play, abduction, and poison ingestion. However, little research on safety skills has been conducted with children with autism. Video modeling has been shown to be effective in teaching abduction prevention skills to children diagnosed with Autism Spectrum Disorder (ASD). The purpose of this study was to evaluate the effectiveness of video modeling to …


An Animal Model Of The Motivational Symptoms Of Depression: Testing The Antidepressant Desipramine On An Effort-Related Choice Task, Samantha L. Collins May 2014

An Animal Model Of The Motivational Symptoms Of Depression: Testing The Antidepressant Desipramine On An Effort-Related Choice Task, Samantha L. Collins

Honors Scholar Theses

Patients with depression, schizophrenia, and other related disorders often show effort-related motivational symptoms such as anergia, psychomotor slowing, lassitude, and fatigue. Several studies have indicated that dopamine (DA) within the nucleus accumbens (NAc) is involved in the regulation of effort-related behavior. Interference with NAc DA alters response allocation in effort related choice procedures, biasing animals towards the alterative that can be obtained with minimal effort. Previous studies have shown that administration of the vesicular monoamine transporter-2 (VMAT-2) inhibitor tetrabenazine (TBZ) shifts behavior in rats responding on the FR5/chow choice procedure causing a decrease in lever pressing and a compensatory increase …

Antioxidant Gene Therapy Against Neuronal Cell Death, Juliana Navarro-Yepes, Laura Zavala-Flores, Anandhan Annadurai, Fang Wang, Maciej Skotak, Namas Chandra, Ming Li, Aglaia Pappa, Daniel Martinez-Fong, Luz Maria Del Razo, Betzabet Quintanilla-Vega, Rodrigo Franco

Department of Psychology: Faculty Publications

Oxidative stress is a common hallmark of neuronal cell death associated with neurodegenerative disorders such as Alzheimer's disease, Parkinson's disease, as well as brain stroke/ischemia and traumatic brain injury. Increased accumulation of reactive species of both oxygen (ROS) and nitrogen (RNS) has been implicated inmitochondrial dysfunction, energy impairment, alterations in metal homeostasis and accumulation of aggregated proteins observed in neurodegenerative disorders, which lead to the activation/modulation of cell death mechanisms that include apoptotic, necrotic and autophagic pathways. Thus, the design of novel antioxidant strategies to selectively target oxidative stress and redox imbalance might represent important therapeutic approaches against neurological disorders. …


The Mental Health Disparity Among Nonheterosexuals: Risk, Resiliency, And New Perspectives To Consider In The Context Of Mormonism, Katherine Ann Crowell May 2014

The Mental Health Disparity Among Nonheterosexuals: Risk, Resiliency, And New Perspectives To Consider In The Context Of Mormonism, Katherine Ann Crowell

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Nonheterosexuals disproportionately experience mental illness when compared with heterosexuals. Although it has been well established that the apparent mental health disparity among sexually diverse populations is almost exclusively derived from minority stress (i.e., the excess stress associated with culturally maintained sexual stigma), our understanding of how specific aspects of minority stress lead to specific psychological syndromes (e.g., depression) remains limited. On the other hand, in attempts to destigmatize individuals who do not identify as heterosexual, researchers have increasingly begun to shift the focus of their work towards understanding the specific characteristics or experiences that facilitate individuals’ capacity to adapt and …


Global Malnutrition: Challenges Associated With Current Intervention Strategies And Prevention Initiatives, Duncan Stiller May 2014

Global Malnutrition: Challenges Associated With Current Intervention Strategies And Prevention Initiatives, Duncan Stiller

Senior Honors Projects

Few, if any, tribulations in the field of public health have managed to transcend the epidemiological transition from acute to chronic disease as malnutrition has. Officially, malnutrition is a category of diseases that includes micronutrient deficiency, under-nutrition (calories/protein), as well as excessive nutrition. The World Food Program estimates that 842 million people worldwide do not have access to enough food, approximately 146 million of which are children. The most serious types of hunger are known as Severe Acute Malnutrition (SAM) and Moderate Acute Malnutrition (MAM), with 20 million and 35 million respective cases each year occurring in children less than …

The aim of this study was to determine the knowledge, attitude and practices regarding HIV/AIDS among adult fishermen in a coastal area of Karachi, Pakistan.

METHODS:

Community based cross sectional study was conducted among fishermen in coastal area of Karachi from June to September 2012. A total of 297 adult …


Psychometric Evaluation Of A Standardized Set Of Alcohol Cue Photographs To Assess Craving, David Edison Lovett May 2014

Psychometric Evaluation Of A Standardized Set Of Alcohol Cue Photographs To Assess Craving, David Edison Lovett

Graduate Theses and Dissertations

To date, research paradigms using alcohol-related stimuli have been limited in their reliability and generalizability due to a lack of published studies examining the psychometric properties of alcohol cues. The primary aim of the current study was to examine the factor structure of a set of alcohol cues and the associated validity and reliability of examining craving for alcohol in an alcohol cue-reactivity paradigm. Participants (N = 195, 74.4% male, 56.4% Asian, Asian American, or Pacific Islander) completed a web-based survey in which valence, arousal, and craving ratings were obtained following presentation of picture cues. Prior to picture cues, participants …


The Impact Of Body Image On Women In Later Life: Effects On Quality Of Life And Body Perception, Rachel L. Avants May 2014

The Impact Of Body Image On Women In Later Life: Effects On Quality Of Life And Body Perception, Rachel L. Avants

Graduate Theses and Dissertations

Physical, mental, and emotional changes can occur throughout the aging process, making it important to treat different age groups as separate populations when researching body image. Yet, very few instruments have been validated for middle-aged and older adults. An online survey was used to perform a validation of the Body Image Quality of Life Inventory (BIQLI) and examine demographic relationships, with a sample of 947 women, ages 40-79, from across the United States. A principal component analysis (PCA) and convergent validity supported the use of the BIQLI for women ages 40 to 79. A one-factor model was validated for comparing …


Openness, Neuroticism, Conscientiousness, And Family Health And Aging Concerns Interact In The Prediction Of Health-Related Internet Searches In A Representative U.S. Sample, Tim Bogg, Phuong T. Vo Apr 2014

Openness, Neuroticism, Conscientiousness, And Family Health And Aging Concerns Interact In The Prediction Of Health-Related Internet Searches In A Representative U.S. Sample, Tim Bogg, Phuong T. Vo

Psychology Faculty Research Publications

Recent estimates suggest 60 % of the U.S. adult population uses the Internet to find health-related information. The goal of the present study was to model health-related Internet searches as a function of an interdependent system of personality adaptation in the context of recent health and aging-related concerns. Assessments of background factors, Big Five personality traits, past-month health and aging-related concerns, and the frequency of past-month health-related Internet searches (via Google, Yahoo, AOL, Bing, or some other search engine) were obtained from a representative U.S. sample (N = 1,015). Controlling for background factors, regression analyses showed more frequent health-related …


Possible Psychosocial Benefits Of Having A Sibling With A Disability, Jenna M. Talbott Apr 2014

Possible Psychosocial Benefits Of Having A Sibling With A Disability, Jenna M. Talbott

Senior Honors Theses

Possible psychosocial benefits resulting from exposure to siblings with disabilities are investigated in the current study. Previous literature has generally overlooked the possibility of psychosocial benefits by exclusively focusing on the negative effects of having a sibling with disabilities. Contact theory suggests that the increased exposure to individuals with disabilities should increase positive attitude toward those who are struggling with disadvantages. This investigation hypothesized that this tendency would be manifested as elevated empathy and compassion in individuals who have siblings with disabilities, and that these traits would be influenced by certain demographic variables. A survey was distributed, and the responses …

Effector-Independent Motor Sequence Representations Exist In Extrinsic And Intrinsic Reference Frames., Tobias Wiestler, Sheena Waters-Metenier, Jörn Diedrichsen Apr 2014

Effector-Independent Motor Sequence Representations Exist In Extrinsic And Intrinsic Reference Frames., Tobias Wiestler, Sheena Waters-Metenier, Jörn Diedrichsen

Brain and Mind Institute Researchers' Publications

Many daily activities rely on the ability to produce meaningful sequences of movements. Motor sequences can be learned in an effector-specific fashion (such that benefits of training are restricted to the trained hand) or an effector-independent manner (meaning that learning also facilitates performance with the untrained hand). Effector-independent knowledge can be represented in extrinsic/world-centered or in intrinsic/body-centered coordinates. Here, we used functional magnetic resonance imaging (fMRI) and multivoxel pattern analysis to determine the distribution of intrinsic and extrinsic finger sequence representations across the human neocortex. Participants practiced four sequences with one hand for 4 d, and then performed these sequences …

Latinos' Health Perceptions: A Cross-Cultural Analyisis, Elizabeth Pappenfus Apr 2014

Latinos' Health Perceptions: A Cross-Cultural Analyisis, Elizabeth Pappenfus

Undergraduate Research Symposium 2014

The purpose of my study is to examine how Latinos’ cultural health beliefs impact their illness behaviors in a rural setting in comparison to White individuals. Illness behavior is defined as the manner in which a person monitors their body, interprets their symptoms, and their reactions to those symptoms. Although Latino immigrants suffer from higher rates of treatable diseases, they are largely underutilizing the healthcare system in the U.S. The Andersen model of healthcare utilization is the most commonly used model for predicting utilization based on the person's environment (i.e. healthcare system) and personal characteristics (i.e. personal need, available resources, …

Participants included 12 visually normal, young adults (mean age = 25.+- 5.2 years) who drove an instrumented research vehicle around a 4 km closed road circuit with three different levels of binocular spherical refractive blur (+0.50 diopter sphere [DS], +1.00 DS, +2.00 DS) compared with a baseline condition. The subjects wore optimal spherocylinder correction and the additional blur lenses were mounted in modified fullfield goggles; the order of testing of the blur conditions was randomized. Driving …


Role Ambiguity Of Counseling Supervisors, Aaron Gabriel Shames Apr 2014

Role Ambiguity Of Counseling Supervisors, Aaron Gabriel Shames

Counseling & Human Services Theses & Dissertations

Supervisors often find themselves in the midst of ambiguity seeking clarity of their role and professional identity within the counseling field. Supervisors wear many hats, the most prominent ones being educator, counselor, and gatekeeper for the profession. Counseling supervisors are expected to establish and maintain a complex blend of professional, educational, and therapeutic relationships with their supervisees. This process involving multiple roles often presents conflicts. One such conflict experienced by supervisors has been termed role ambiguity. The purpose of this phenomenological inquiry was to explore what experiences counseling supervisors have with role ambiguity and how they experience role ambiguity. Themes …

Psychology Faculty Research and Publications

This study investigated mechanisms for the stressor-induced changes in muscle fatigability in men and women. Participants performed an isometric-fatiguing contraction at 20% maximal voluntary contraction (MVC) until failure with the elbow flexor muscles. Study one (n = 55; 29 women) involved two experimental sessions: 1) a high-stressor session that required a difficult mental-math task before and during a fatiguing contraction and 2) a control session with no mental math. For some participants (n = 28; 14 women), cortical stimulation was used to examine mechanisms that contributed to muscle fatigability during the high-stressor and control sessions. Study two …


Impulsive Choice In Unmedicated And Medicated Children Diagnosed With Adhd: Examining The Variables Of Reward Type And Adhd Subtype, Nicole Henriksen Apr 2014

Impulsive Choice In Unmedicated And Medicated Children Diagnosed With Adhd: Examining The Variables Of Reward Type And Adhd Subtype, Nicole Henriksen

Dissertations

Developmentally inappropriate and impairing impulsive behaviors are often seen in attention-deficit/hyperactivity disorder (ADHD). One method for objectively assessing impulsivity is the Choice-Delay Task (C-DT) which presents repeated opportunities to choose between a smaller, sooner (SS) or larger, later (LL) reward. A preference for the SS reward that results in less total reward is considered impulsive. Many studies have found that participants diagnosed with ADHD choose the SS reward more than typical controls. However, less is known about the effects of different types of rewards, or the comparative performance of certain subgroups, such as children diagnosed with ADHD Predominantly Inattentive Type …
