Traumatic Brain Injury In Adolescence: The Relationship Between High School Exiting And Future Productivity, Jeffrey S. Garofano Jul 2017

Traumatic Brain Injury In Adolescence: The Relationship Between High School Exiting And Future Productivity, Jeffrey S. Garofano

USF Tampa Graduate Theses and Dissertations

Traumatic brain injury (TBI) is the leading cause of death and disability among children and adolescents. Brain injury survivors are often left with persistent impairments that have the potential to impede daily functioning, delay or prevent the attainment of developmental milestones, and subsequently limit future productivity in adulthood. A shared goal of both neurorehabilitation and the educational system is to prepare youth for a productive adulthood with both systems of care having substantial, yet independent, literature bases regarding factors associated with productivity (e.g., engagement in employment or post-secondary education). It is currently assumed that because type of high school exiting …

Optimizing Emergency Department Throughput Using Best Practices To Improve Patient Flow, Puneet Freibott Dnp, Rn, Nea-Bc, Ccrn-K'S Jul 2017

Optimizing Emergency Department Throughput Using Best Practices To Improve Patient Flow, Puneet Freibott Dnp, Rn, Nea-Bc, Ccrn-K'S

Journal of Nursing & Interprofessional Leadership in Quality & Safety

Emergency Department (ED) crowding and bottle necks are the reality of hospitals across the country. Patients seeking care and needing inpatient beds via the emergency rooms are facing delays with attaining the right level of care. Orchestrating a patient through an ED admission requires a multidisciplinary effort to provide safe, effective and efficient care. This quality improvement project conducted in a tertiary acute care hospital focused on Centers for Medicare and Medicaid metrics to measure Emergency Department (ED) throughput. This multidisciplinary initiative focused on reducing time stamps for patient arrival to the ED through departure to hospital or home. Outcomes …

The Relationships Between Nonsuicidal Self-Injury Frequency And Suicidal Behaviors, Depression, And Anxiety: A Curvilinear Analysis, Sherry Elizabeth Woods Jul 2017

The Relationships Between Nonsuicidal Self-Injury Frequency And Suicidal Behaviors, Depression, And Anxiety: A Curvilinear Analysis, Sherry Elizabeth Woods

Masters Theses & Specialist Projects

Nonsuicidal self-injury (NSSI) involves the deliberate damage of one’s own bodily tissue without suicidal intent. A number of psychological disorders and indicators of distress are correlated with the behavior, including suicidal behaviors (e.g. Whitlock & Knox, 2007), depression (e.g. Ross & Heath, 2002), and anxiety (e.g. Victor & Klonksy, 2014), and yet the research literature has been mixed on whether increased frequency of NSSI is correlated with increased levels of these variables. The present study hypothesized that these relationships are curvilinear. Data from a larger study were analyzed using curvilinear regression analyses, and hypotheses were partially supported. Curvilinear relationships were …

Rapid Statistical Learning Supporting Word Extraction From Continuous Speech., Laura J Batterink Jul 2017

Rapid Statistical Learning Supporting Word Extraction From Continuous Speech., Laura J Batterink

Brain and Mind Institute Researchers' Publications

The identification of words in continuous speech, known as speech segmentation, is a critical early step in language acquisition. This process is partially supported by statistical learning, the ability to extract patterns from the environment. Given that speech segmentation represents a potential bottleneck for language acquisition, patterns in speech may be extracted very rapidly, without extensive exposure. This hypothesis was examined by exposing participants to continuous speech streams composed of novel repeating nonsense words. Learning was measured on-line using a reaction time task. After merely one exposure to an embedded novel word, learners demonstrated significant learning effects, as revealed by …

Social Rejection Magnifies Impulsive Behavior Among Individuals With Greater Negative Urgency: An Experimental Test Of Urgency Theory, David S. Chester, Donald R. Lynam, Richard S. Milich, C. Nathan Dewall Jul 2017

Social Rejection Magnifies Impulsive Behavior Among Individuals With Greater Negative Urgency: An Experimental Test Of Urgency Theory, David S. Chester, Donald R. Lynam, Richard S. Milich, C. Nathan Dewall

Psychology Faculty Publications

Impulsivity is a multifaceted trait with substantial implications for human well-being. One facet of impulsivity is negative urgency, the tendency to act impulsively in response to negative affect. Correlational evidence suggests that negative affect magnifies impulsive behavior among individuals with greater negative urgency, yet causal evidence for this core pillar of urgency theory is lacking. To fill this gap in the literature, participants (N = 363) were randomly assigned to experience social rejection (a situation shown to induce negative affect) or acceptance. Participants then reported their subjective negative affect, completed a behavioral measure of impulsivity, and reported their negative …

Trigger Warnings: From Panic To Data, Francesca Laguardia, Venezia Michalsen Jul 2017

Trigger Warnings: From Panic To Data, Francesca Laguardia, Venezia Michalsen

Department of Justice Studies Faculty Scholarship and Creative Works

Following a practice originated online, university faculty and staff have increasingly used “trigger warnings” to alert students to the possibility that they might be affected or even harmed by potentially traumatic material. This practice has led to a passionate debate about whether such warnings stifle or encourage student expression and academic freedom, and whether they are beneficial or detrimental to learning. In this article, we illustrate the history and current state of this debate, and examine the scientific support for the arguments for and against the use of such warnings. Specifically, we question the scientific basis for the suggestion that …

Aging, Executive Function, Fronto-Parietal Network Cortical Thickness: Insights From Cognitive Reserve, Katherine Reiter Jul 2017

Aging, Executive Function, Fronto-Parietal Network Cortical Thickness: Insights From Cognitive Reserve, Katherine Reiter

Dissertations (1934 -)

Cognitive reserve (CR) indexes the nonlinear relationship between neurological insult and behavioral change. CR is manifested in both static factors (e.g., childhood environment, education) and modifiable lifestyle factors, (e.g., leisure activities). Detailed investigation of the influence of CR on cortical thickness, which indexes neuropathology, and cognitive functioning could be particularly important in understanding the heterogeneity of Alzheimer’s disease (AD). While memory decline is the hallmark of AD, executive functioning (EF) decline often predates memory changes, making EF an important target for investigating CR influences. The current study examines the relationship of CR and genetic risk for AD (ε4) on EF …

Examining The Durability Of Peers For Adolescents With Asd: Maintenance Of Neurological And Behavioral Effects, Bridget Kathleen Dolan Jul 2017

Examining The Durability Of Peers For Adolescents With Asd: Maintenance Of Neurological And Behavioral Effects, Bridget Kathleen Dolan

Dissertations (1934 -)

To date, there are no known published studies that have assessed the maintenance of treatment effects in the context of neurological changes and their relationship to behavioral outcomes following a social skills intervention for adolescents with Autism Spectrum Disorder (ASD). The few studies that have incorporated long-term assessment into their design have focused exclusively on sustained behavioral responses to treatment. Individuals with ASD across the lifespan exhibit aberrant neural activity, which is thought to underlie social skill deficits noted in persons on the spectrum. Thus, this study sought to examine the impact of a social skills intervention, the Program for …

Predictive Value Of Adhd Symptomatology On Motives And Outcomes Of Stimulant Misuse, Alexander Laszlo Peterkin Jul 2017

Predictive Value Of Adhd Symptomatology On Motives And Outcomes Of Stimulant Misuse, Alexander Laszlo Peterkin

Psychology Theses & Dissertations

ADHD stimulant misuse is defined as taking a stimulant used to treat ADHD either without having a prescription for that stimulant or in a manner that deviates from the prescription’s instructions. This has been a growing trend among undergraduate students over recent years. Prior research has found that misusers are likely to have severe symptoms of ADHD, misuse for primarily academic reasons, and display problems associated with substance abuse. The current study aimed to determine the predictive value of ADHD symptomatology on frequency of ADHD stimulant misuse, mediated by academic motives for misuse and substance abuse problems. The survey for …

Breaking The Silence: A Phenomenological Exploration Of Secondary Traumatic Stress In U.S. College Student Affairs Professionals, Robert Jason Lynch Jul 2017

Breaking The Silence: A Phenomenological Exploration Of Secondary Traumatic Stress In U.S. College Student Affairs Professionals, Robert Jason Lynch

Educational Leadership & Workforce Development Theses & Dissertations

Breaking the Silence: A Phenomenological Exploration of Secondary Traumatic Stress in U.S. College Student Affairs Professionals is a qualitative-intensive mixed methods study using phenomenology and art-based research techniques to uncover the essence of secondary traumatic stress in U.S. college student affairs professionals. Researchers in the fields of psychology, counseling, social work and other helping professions suggest that repeated exposure to individuals experiencing trauma, or hearing repeated details of an individual’s trauma, have negative outcomes on professional helpers. Coined secondary traumatic stress, this phenomenon may be defined as “the stress resulting from helping or wanting to help a traumatized or suffering …

Protective Factors Against Peer And Social Media Sex Messages: The Moderating Role Of Parental Influences On African American Emerging Adult Students' Sexual Behaviors, Jacqueline Eunice Haywood Jul 2017

Protective Factors Against Peer And Social Media Sex Messages: The Moderating Role Of Parental Influences On African American Emerging Adult Students' Sexual Behaviors, Jacqueline Eunice Haywood

Psychology Theses & Dissertations

The most recent research on risky sexual behaviors is primarily based on adolescent, predominately White, or multiple race (e.g., African American and White) samples. There is a paucity of literature focused exclusively on African Americans, particularly African American emerging adults between the ages of 18 and 25. Given the increased risk for sexually transmitted infections (STIs) for college aged African Americans, it is important to understand factors that may decrease engaging in risky sexual behaviors that are specific to this group. The current study examined the roles of parental warmth and communication about sex as protective factors. Participants (n = …

The Relationship Of Early Class Start Times On Sleepiness And Driving Behaviors In An Emerging Adult Population, Jessica L. Fry Jul 2017

The Relationship Of Early Class Start Times On Sleepiness And Driving Behaviors In An Emerging Adult Population, Jessica L. Fry

Psychology Theses & Dissertations

Teenage driver sleepiness is a recent concern for preventing motor vehicle fatalities. Early school start times limit the amount of sleep teenage high school students acquire during the week and have been related to increased crash risk. The current study extends this finding to teenage and emerging adult college students. The author examined the link between sleepiness and teenage driving behaviors, including the relationship between school start times and sleepiness. In all, 536 participants were recruited to participate in an online survey assessing driving and sleep behaviors. Correlations and path analysis found that sleepiness fully mediated the relationship between early …

Using Business Modeling To Streamline Cost Of Anesthesia In A Cardiopulmonary Laboratory, Johnny Dang Dnp, Crna, Kristen Starnes-Ott Phd, Crna Jun 2017

Using Business Modeling To Streamline Cost Of Anesthesia In A Cardiopulmonary Laboratory, Johnny Dang Dnp, Crna, Kristen Starnes-Ott Phd, Crna

Journal of Nursing & Interprofessional Leadership in Quality & Safety

The Time Driven Activity Based Costing (TDABC) measurement system, a model used in the business arena, can capture clinical processes and costs that other costing models often overlook. Use of this system permitted tying costs to time and resources and identified areas of inefficiency such as depleted supplies and health care and emergency supplies placed inconveniently. A multidisciplinary team developed an anesthesia checklist for use in a remote cardiopulmonary laboratory. The compliance rate for checklist completion was approximately 85%. Checklist implementation translated to a decrease in case delays and time expenditure in patient care by 58% with a cost savings …

Understanding Gender Differences In Sports-Related Concussions Among High School Athletes: Implications For Diagnosis, Treatment, And Management, Hillary Grady-Speckhals Jun 2017

Understanding Gender Differences In Sports-Related Concussions Among High School Athletes: Implications For Diagnosis, Treatment, And Management, Hillary Grady-Speckhals

Graduate School of Professional Psychology: Doctoral Papers and Masters Projects

Growing research on both the immediate and long-term effects of sports-related concussions (SRCs) in professional athletes has called attention not only to understanding the impact of concussions in high school athletes, but has also focused on understanding how SRCs may impact female athletes differently than male athletes (Covassin & Elbin, 2011; Kirkwood, Yeates, & Wilson, 2006). There are many studies that have highlighted the neurocognitive, academic, and socioemotional implications of these brain injuries on developing youth, but there are few studies that focus on gender differences in adolescent athletes (Daneshvar, Nowinski, McKee, & Cantu, 2011; Kirkwood, et al., 2006). Understanding …

Abnormal Dendritic Maturation Of Developing Cortical Neurons Exposed To Corticotropin Releasing Hormone (Crh): Insights Into Effects Of Prenatal Adversity?, Megan M. Curran, Curt A. Sandman, Elysia Poggi Davis, Laura M. Glynn, Tallie Z. Baram Jun 2017

Abnormal Dendritic Maturation Of Developing Cortical Neurons Exposed To Corticotropin Releasing Hormone (Crh): Insights Into Effects Of Prenatal Adversity?, Megan M. Curran, Curt A. Sandman, Elysia Poggi Davis, Laura M. Glynn, Tallie Z. Baram

Psychology: Faculty Scholarship

Corticotropin releasing hormone (CRH) produced by the hypothalamus initiates the hypothalamic-pituitary-adrenal (HPA) axis, which regulates the body’s stress response. CRH levels typically are undetectable in human plasma, but during pregnancy the primate placenta synthesizes and releases large amounts of CRH into both maternal and fetal circulations. Notably, placental CRH synthesis increases in response to maternal stress signals. There is evidence that human fetal exposure to high concentrations of placental CRH is associated with behavioral consequences during infancy and into childhood, however the direct effects on of the peptide on the human brain are unknown. In this study, we used a …

Can We Talk?: Synergistic Effects Of Cognitive And Behavioral Frameworks To Address Substance Use And Abuse, Lauren Jaye Adams Jun 2017

Can We Talk?: Synergistic Effects Of Cognitive And Behavioral Frameworks To Address Substance Use And Abuse, Lauren Jaye Adams

USF Tampa Graduate Theses and Dissertations

Behavioral economic accounts of substance use have provided a novel framework to examine constraints that affect behaviorally driven outcomes. Several behavioral studies support the application of such frameworks to examine impulsive decision-making processes as well as how subjective reward influences substance use. Based on stimulus-response models, behavioral economic research often applies mathematical formulas to draw conclusions about behavioral outcomes. These mathematical formulas, while useful, largely ignore decades of cognitive psychology research that have examined state-based influences (e.g., mood, environment, motivational processes, etc.) on behavioral sequelae. To address this issue, the present study merged a cognitive framework into two behavioral economic …

Latent Profile Analysis Of The Five Facet Mindfulness Questionnaire In A Sample With A History Of Recurrent Depression, Jenny Gu, Anke Karl, Ruth A. Baer, Clara Strauss, Thorsten Barnhofer, Catherine Crane

Psychology Faculty Publications

Background: Extending previous research, we applied latent profile analysis in a sample of adults with a history of recurrent depression to identify subgroups with distinct response profiles on the Five Facet Mindfulness Questionnaire and understand how these relate to psychological functioning. Method: The sample was randomly divided into two subsamples to first examine the optimal number of latent profiles (test sample; n = 343) and then validate the identified solution (validation sample; n = 340). Results: In both test and validation samples, a four-profile solution was revealed where two profiles mapped broadly onto those previously identified in nonclinical samples: “high …

The Implications Of Using A Broad Versus Narrow Set Of Criteria In Research, Leonard A. Jason, Kristen D. Gleason Phd, Pamela Fox

Faculty Publications

The Fukuda et al. criteria is the most widely used clinical case definition for diagnosing patients with chronic fatigue syndrome (CFS). Despite the frequency with which the Fukuda criteria are applied, the list of symptoms outlined in this case definition were not well enough specified to be easily applied to research settings. In 2005, Reeves et al. laid out a set of standards for operationalizing the Fukuda definition, specifying scales and cutoff scores for measuring the symptom criteria. This operationalization, often known as the empirical criteria, has been shown to identify an unexpectedly large number of patients, seemingly widening the …

Spatial-Relational Learning And Memory Deficits Associated With Nmdar Autoantibodies In Systemic Lupus Erythematosus, Brittany L. Bascetta Jun 2017

Spatial-Relational Learning And Memory Deficits Associated With Nmdar Autoantibodies In Systemic Lupus Erythematosus, Brittany L. Bascetta

Dissertations, Theses, and Capstone Projects

Individuals with Systemic Lupus Erythematosus (SLE) experience inflammation that may target any organ within the body, including the central and peripheral nervous systems. Additionally, these individuals often demonstrate psychological dysfunctions including emotional and cognitive deficits; however, research is inconsistent as to the nature and cause of these dysfunctions. While there are multiple factors that may increase risk for variability in cognitive function, such as population differences, socioeconomic status (SES), mood disorders (depression and anxiety), medication effects, and disease activity, these factors do not reliably predict the severity and extent of cognitive deficits. A growing body of animal research associates autoantibodies …

Longitudinal Analyses Of The Sexual And Reproductive Health Knowledge And Parent-Adolescent Communication Of At-Risk Adolescents, Courage Chikomborero Mudzongo Jun 2017

Longitudinal Analyses Of The Sexual And Reproductive Health Knowledge And Parent-Adolescent Communication Of At-Risk Adolescents, Courage Chikomborero Mudzongo

Faculty Publications - Doctor of Psychology (PsyD) Program

Despite declining rates, unintended adolescent pregnancy remains a considerable public health challenge in the United States (Hamilton, Martin, & Osterman, 2015). Unintended pregnancy leads to a host of negative outcomes not only for adolescents, but also for their children who are more likely to get trapped in a cycle of poverty that is difficult to break (Rew & Wong, 2006). Factors such as poverty are difficult to address; nonetheless, sexual reproductive health (SRH) knowledge and parent-adolescent communication (PAC) have been identified as important tools for prevention, and potentially modifiable (Swenson et al., 2009; 2010). The goal of the current study …

Stimulus-Selectivity Of Drug Purchase Tasks: A Preliminary Study Evaluating Alcohol And Cigarette Demand, Justin Charles Strickland, William W. Stoops Jun 2017

Stimulus-Selectivity Of Drug Purchase Tasks: A Preliminary Study Evaluating Alcohol And Cigarette Demand, Justin Charles Strickland, William W. Stoops

Psychology Faculty Publications

The use of drug purchase tasks to measure drug demand in human behavioral pharmacology and addiction research has proliferated in recent years. Few studies have systematically evaluated the stimulus selectivity of drug purchase tasks to demonstrate that demand metrics are specific to valuation of or demand for the commodity under study. Stimulus selectivity is broadly defined for this purpose as a condition under which a specific stimulus input or target (e.g., alcohol, cigarettes) is the primary determinant of behavior (e.g., demand). The overall goal of the present study was to evaluate the stimulus selectivity of drug purchase tasks. Participants were …

Zohar and Luria’s (2005) safety climate (SC) scale, measuring organization- and group- level SC each with 16 items, is widely used in research and practice. To improve the utility of the SC scale, we shortened the original full-length SC scales. Item response theory (IRT) analysis was conducted using a sample of 29,179 frontline workers from various industries. Based on graded response models, we shortened the original scales in two ways: (1) selecting items with above-average discriminating ability (i.e. offering more than 6.25% of the original total scale information), resulting in 8-item organization-level and 11-item group-level SC scales; and (2) selecting …

Effects Of Low Dose Mixtures Of 3,4-Methylenedioxypyrovalerone And Cocaine On Locomotor Activity And Brain Monoamine Content In Sprague-Dawley Rats, Robert J. Kohler Jun 2017

Effects Of Low Dose Mixtures Of 3,4-Methylenedioxypyrovalerone And Cocaine On Locomotor Activity And Brain Monoamine Content In Sprague-Dawley Rats, Robert J. Kohler

Masters Theses

Synthetic cathinones, known as “bath salts” on the illicit drug market, pose a significant and growing public health concern. 3,4-Methylenedioxypyrovalerone (MDPV), one of several popular constituents of the illicit bath salts, produces similar pharmacological actions to cocaine, albeit with greater potency. The present study sought to characterize behavioral and neurochemical effects of repeated exposure to MDPV alone and in combination with cocaine. Male Sprague-Dawley rats were randomly assigned to one of four treatments: 1 mg/kg MDPV, 5 mg/kg cocaine, 1 mg/kg MDPV + 5 mg/kg cocaine, or saline. Locomotor activity was assessed for one hour immediately before and one hour …
