Exploring A Multifactorial, Clinical Model Of Thought Disorder : Application Of A Dimensional, Transdiagnostic Approach., Mara Ann Hart

Electronic Theses and Dissertations

Background: Bleuler saw thought disorder as the core defining feature of psychotic phenomena, reflective of the “splitting of the psychic functions” that occurred when, in the process of thinking, one’s ideas and feelings disconnect, becoming fragmented and competing functions. Unfortunately, interest in thought disorder as the conceptual core of psychosis was lost with rise of the modern DSM system, paralleling the shift towards a more simplistic, categorical way of defining psychiatric disorders. Aims: This study examined thought disorder from a dimensional perspective, with the aim of disentangling qualitative heterogeneity and diverse sources of influence. Analyses were based on …

Examining The Protective Effect Of Ethnic Identity On Drug Attitudes And Use Among A Diverse Youth Population, Tamika C. B. Zapolski, Sycarah Fisher, Devin E. Banks, Devon J. Hensel, Jessica Barnes-Najor

Educational, School, and Counseling Psychology Faculty Publications

Ethnic identity is an important buffer against drug use among minority youth. However, limited work has examined pathways through which ethnic identity mitigates risk. School-aged youth (N = 34,708; 52 % female) of diverse backgrounds (i.e., African American (n = 5333), Asian (n = 392), Hispanic (n = 662), Multiracial (n = 2129), Native American (n = 474), and White (n = 25718) in grades 4–12 provided data on ethnic identity, drug attitudes, and drug use. After controlling for gender and grade, higher ethnic identity was associated with lower past month drug use …

Impulsive Personality Dimensions Are Associated With Altered Behavioral Performance And Neural Responses In The Monetary Incentive Delay Task, Ruolei Gu, Yang Jiang, Seth Kiser, Chelsea L. Black, Lucas S. Broster, Yue-Jia Luo, Thomas H. Kelly

Behavioral Science Faculty Publications

Individual differences in dimensions of impulsivity personality including disinhibition and sensation seeking modulate approach responses to reinforcing stimuli, such as drugs and money. The current study examined the effects of monetary incentive on both behavioral performance and electrophysiological activity among individuals varying in disinhibition and sensation seeking. The monetary incentive delay (MID) task was completed under electroencephalogram (EEG) recording. Behavioral data showed that higher disinhibition and sensation-seeking were associated with lower performance accuracy. Event-related potential (ERP) data showed that high reinforcement cues elicited a larger late positive component (LPC) than other conditions among high disinhibition participants, indicating its strong emotional …

Do Eye Movements During Shape Discrimination Reveal An Underlying Geometric Structure?, Bradley R. Sturz, Ty W. Boyer, John F. Magnotti, Kent D. Bodily

Psychology: Faculty Publications

Using a psychophysical approach coupled with eye-tracking measures, we varied length and width of shape stimuli to determine the objective parameters that corresponded to subjective determination of square/rectangle judgments. Participants viewed a two-dimensional shape stimulus and made a two-alternative forced-choice whether it was a square or rectangle. Participants’ gaze was tracked throughout the task to explore directed visual attention to the vertical and horizontal axes of space. Behavioral results provide threshold values for two-dimensional square/rectangle perception, and eye-tracking data indicated that participants directed attention to the major and minor principal axes. Results are consistent with the use of the major …

Cahost: An Excel Workbook For Facilitating The Johnson-Neyman Technique For Two-Way Interactions In Multiple Regression, Stephen W. Carden, Nicholas S. Holtzman, Michael J. Strube

Psychology: Faculty Publications

When using multiple regression, researchers frequently wish to explore how the relationship between two variables is moderated by another variable; this is termed an interaction. Historically, two approaches have been used to probe interactions: the pick-a-point approach and the Johnson-Neyman (JN) technique. The pick-a-point approach has limitations that can be avoided using the JN technique. Currently, the software available for implementing the JN technique and creating corresponding figures lacks several desirable features–most notably, ease of use and figure quality. To fill this gap in the literature, we offer a free Microsoft Excel 2013 workbook, CAHOST (a concatenation of the first …

Pilot And Feasibility Test Of An Implementation Intention Intervention To Improve Fruit And Vegetable Intake Among Women With Low Socioeconomic Status, Michele A. Debiasse Phd, Rdn, Deborah J. Bowen Phd, Sherry L. Pagoto Phd, Joseph M. Massaro Phd, Nawfal Istfan Md, Phd, Lisa M. Quintiliani Phd, Rd

Journal of Health Disparities Research and Practice

Fruit and vegetable intake (FVI), a modifiable risk factor for chronic diseases, is lower in low socioeconomic status (SES) populations. Implementation intentions (a specific type of planning that extends the Theory of Planned Behavior) has been studied to improve FVI, but not exclusively with low SES groups. Using mixed methods, we evaluated the feasibility, acceptability, and preliminary efficacy of an implementation intention intervention (versus a general plan) to increase FVI in women with low SES. For the pilot randomized controlled trial, demographics, body mass index, attitude, perceived behavioral control, goal intention strength, and FVI were measured at baseline and FVI …

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 …

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 …

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 …

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 …

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 …

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 …

Neurophysiological Capacity In A Working Memory Task Differentiates Dependent From Nondependent Heavy Drinkers And Controls, Michael J. Wesley, Joshua A. Lile, Mark T. Fillmore, Linda J. Porrino

Behavioral Science Faculty Publications

Background—Determining the brain-behavior profiles that differentiate heavy drinkers who are and are not alcohol dependent will inform treatment efforts. Working memory is linked to substance use disorders and can serve as a representation of the demand placed on the neurophysiology associated with cognitive control.

Methods—Behavior and brain activity (via fMRI) were recorded during an N-Back working memory task in controls (CTRL), nondependent heavy drinkers (A-ND) and dependent heavy drinkers (A-D). Typical and novel step-wise analyses examined profiles of working memory load and increasing task demand, respectively.

Results—Performance was significantly decreased in A-D during high working memory load …

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 …

Increasing Access To Aba Intervention For Children With Developmental Disabilities In Taiwan, Noel Hsu

Master's Projects and Capstones

Applied Behavior Analysis (ABA) uses a behavioral approach to help clients and their behavioral challenges. This treatment has been proven to be a highly effective intervention for children with developmental disabilities, such as autism spectrum disorders. It is widely practiced in the United States and many other developed countries; however, this intervention is not widely available in Taiwan. This phenomenon requires our investigation because it raises questions about the available supports and interventions for children with special needs in Taiwan. This project is to explore factors that influence the development of ABA intervention in Taiwan. The goal of this project …

Computational Modeling Of Contrast Sensitivity And Orientation Tuning In Schizophrenia, Steven M. Silverstein, Docia L. Demmin, James A. Bednar

MODVIS Workshop

Computational modeling is being increasingly used to understand schizophrenia, but, to date, it has not been used to account for the common perceptual disturbances in the disorder. We manipulated schizophrenia-relevant parameters in the GCAL (gain control, adaptation, laterally connected) model (Stevens et al., 2013), run using the Topographica simulator (Bednar, 2012), to model low-level visual processing changes in the disorder. Our models incorporated: separate sheets for retinal, LGN, and V1 activity; gain control in the LGN; homeostatic adaptation in V1 based on a weighted sum of all inputs and limited by a logistic (sigmoid) nonlinearity; lateral excitation and inhibition in …

Sleep Deprivation And Voluntary Alcohol Consumption In Adult Rats, Charles M. Cowan Ii

Masters Theses, 2010-2019

Alcohol is a psychoactive drug with a large userbase among adults across the globe. However, alcohol use also reduces the quality of sleep in the user. Historically, research has focused on the effects of alcohol on sleep architecture, but recent research has started to examine the effects of sleep deprivation on alcohol consumption. This research examines the effects of sleep deprivation on voluntary alcohol consumption in adult rats. Twelve Sprague Dawley rats were given ad libitum access to food, alcohol (7% solution), and water for the duration of this study. Subjects were then placed into non-moving forced exercise wheels to …

Provider Based Interventions To Mitigate Risk For Opioid Pain Medication Abuse Among Adult Patients In A Primary Care Setting, Sheree Lamara Conley-Donaldson

Doctoral Projects

Mental and substance use disorders are predicted to exceed all physical disease processes causing major disability by 2020. Misuse and overdose of opioid pain medications is a significant public health concern in the United States. Approximately 1 in 4 patients receiving prescription opioids in primary care settings struggle with misuse. Half of all opioid prescriptions are written by primary care providers, including nurse practitioners. The purpose of this DNP project was to determine if nurse practitioner providers are implementing evidence-based practice guidelines including screening, brief intervention, and referral to treatment (SBIRT) to mitigate risk of prescription opioid pain medication misuse …

Mental Health 101: Teaching Students And Campus Leaders How To Help Those In Crisis, Megan B. Kuhnly

Senior Honors Projects

One in four Americans ages 18 and older live with a diagnosable mental health disorder. Due to this high prevalence it is very likely that everyone will encounter someone dealing with a mental health crisis in his or her lifetime. Many college students will experience a crisis during their four years of study due to the high levels of stress and psychological triggers. However, we are often not taught how to help these individuals and the resources available are not well advertised. This lack of education and awareness leads to many students being forced to suffer alone and their mental …

Humor In Medicine: A Literature Review Of Humor’S Potential Therapeutic Value In Health Care, Weston Michael Grant

Psychological Science Undergraduate Honors Theses

Using humor and laughter within the health care field has the potential to be relevant to patients during treatment, to the patient-caregiver relationship, to the subjective well-being of health care providers, and to the environments’ (e.g., work settings) impact on group relationships (e.g., colleagues). A review of the literature examines how the psychological and physiological effects of laughter and humor within the human body impact health and well-being, how humor and laughter improve the patient-practitioner relationship, and if humor and laughter can potentially impact physician burnout. Several possible implications for these findings are discussed, such as professional medical comedians, improvements …

The Experience Of Generalized Anxiety Disorder Through The Lens Of Abraham Lincoln: The Effects Of Mental Health Stigma, Daryl Claude Medina

Senior Theses

Living with generalized anxiety disorder, also known as GAD, in the United States of America is difficult not only for the individual, but also for the people around him or her. Lifestyle changes have to be made, family dynamics need to be adjusted, and last but not least, all relationships must become flexible. In fact, these major life changes are never fixed and must continually adapt to the needs of the individual with generalized anxiety disorder since it is a lifelong medical condition. As with any other mental illness, dealing with generalized anxiety disorder takes great sacrifice in terms of …

Temperament And Behavior Factors In A Community Sample Of Youth With Selective Mutism, Rachele Alexandra Diliberto

UNLV Theses, Dissertations, Professional Papers, and Capstones

Children with selective mutism often present as a very diverse population, with both oppositional (APA, 2013; Cohan et al., 2008; Steinhausen & Juzi, 1996), and anxious symptoms (APA, 2013; Kristensen, 2000; Vecchio & Kearney, 2009) most commonly reported. The first aim of the current study was to validate the presence of previously identified anxious and oppositional behavior factors in a community sample of youth with selective mutism. These factors were previously identified in a clinic sample of youth with selective mutism (Diliberto & Kearney, 2016). The second aim was to examine the association of anxious and oppositional behavior factors with …

Reconnecting The Mind And Body: A Pilot Study Of Developing Compassion For Persistent Pain, Sarah L. Parry Dr, Zoey Malpus Dr

Patient Experience Journal

As an alternative to the more typical cognitive behavioural approach to pain management, a novel pain management group based on the principles of compassionate mind training was developed for a particular sub-group of patients. Participants were patients of a community pain clinic, who were invited to participate in this alternative approach to pain management. The eight-week Compassion in Pain Groups included psychoeducation around persistent pain, the underlying principles of compassionate mind training, practical exercises such as diaphragmatic breathing, followed by a series of compassionate imagery exercises and group discussions. Both quantitative and qualitative analyses were undertaken to gain further insights …

Psychotherapy Is Chaotic— (Not Only) In A Computational World, Günter K. Schlepek, Kathrin Vol, Wolfgang Aichhorn, Marc-Thorsten Hütt, Katharina Sungler, David Pincus, Helmut J. Schöller

Psychology Faculty Articles and Research

Objective: The aim of this article is to outline the role of chaotic dynamics in psychotherapy. Besides some empirical findings of chaos at different time scales, the focus is on theoretical modeling of change processes explaining and simulating chaotic dynamics. It will be illustrated how some common factors of psychotherapeutic change and psychological hypotheses on motivation, emotion regulation, and information processing of the client’s functioning can be integrated into a comprehensive nonlinear model of human change processes.

Methods: The model combines 5 variables (intensity of emotions, problem intensity, motivation to change, insight and new perspectives, therapeutic success) and …

The Effect Of Routine Adult Phq-2 Depression Screen And Scheduled Follow-Up Protocol In The Primary Care Setting, Alex F. Bikowski

Evidence-Based Practice Project Reports

Healthy People has projected depression to be the primary cause of disability by 2020; therefore routine depression screening has been prioritized as a national healthcare initiative. The purpose of this Evidence-Based Practice (EBP) project is to demonstrate that routine implementation of the 2-item Patient Health Questionnaire (PHQ-2) depression screener, along with a scheduled follow-up protocol for adults in the primary care setting, can improve current mental health practices regarding the identification of depression by clinicians. The evidence supports use of the PHQ-2 for routine adult depression screening, as long as a scheduled follow-up protocol is available for positive screens. This …

The Phenomenon Of Teacher Burnout: Mitigating Its Influence On New Teachers, Kaila Sanford

Scholarly and Creative Works Conference (2015 - 2021)

Burnout is a psychological condition with physical, emotional, and mental dimensions. Burnout often includes feelings of exhaustion, long-term fatigue, negative self-concept, despair or hopelessness, frustration, and a lack of productivity at work.

Teacher burnout is a well-known and researched field. It has been documented in the literature that teachers experience high levels of stress and emotional exhaustion, which leads to high levels of burnout and professional attrition. This study examined the incidence of burnout in new elementary school teachers and makes recommendations for changes to organizational structure that may reduce professional burnout.

For the purpose of this study five new …
