The Examination Of A Mobile Application For The Reduction Of Posttraumatic Stress Related Symptoms In Emergency Dispatchers, Emy Willis May 2019

The Examination Of A Mobile Application For The Reduction Of Posttraumatic Stress Related Symptoms In Emergency Dispatchers, Emy Willis

Electronic Theses and Dissertations

Emergency dispatchers report that their jobs are stressful, yet there are few controlled investigations examining their specific psychological complaints. Additionally, research examining the use of interventions directed at alleviating their work-related stress is limited. This study aims to examine the efficacy and feasibility of a mobile application (PTSD Coach) on various indicators of psychosocial well-being among emergency telecommunicator dispatchers. A sample of 117 emergency dispatchers completed self-report psychological mood assessments at baseline, weekly for five weeks during PTSD Coach use and post-treatment. Participant report of psychological symptoms showed statistically significant decreases in mood severity over the period of one month.


Group Composition Characteristics As Predictors Of Shared Leadership: An Exploration Of Competing Models Of Shared Leadership Emergence, Richard Currie May 2019

Group Composition Characteristics As Predictors Of Shared Leadership: An Exploration Of Competing Models Of Shared Leadership Emergence, Richard Currie

Electronic Theses and Dissertations

The study of leadership in organizations has received much research attention over the past several decades. However, most of this research has examined hierarchical structures of leadership wherein one individual leads, or is perceived to lead, several other individuals. With a growing number of organizations structuring employees within teams or work groups, researchers have begun studying the ways in which leadership operates in groups. One alternative to the traditional hierarchical structure is for leadership to be distributed or shared in groups such that multiple group members contribute to the overall leadership function of the group. As a result, researchers have ...

The Profession Of Modeling And Simulations: Unifying The Organization, John Lord

Electronic Theses and Dissertations

The organization of Modeling and Simulation (M&S) as a profession started in the early twenty-first century spurred by the advent of computers and the vast networking capabilities of contemporary computing. M&S is still in its infancy when compared to other disciplines, such as engineering, computer science and mathematics. However, the profession has experienced significant growth in part due to the varied use of M&S techniques and tools within almost every discipline. Professional organizations and academic programs supporting M&S across the country have started to materialize. In a short timeframe, the growth of these supporting organizations has ...


Predicting Counterproductive Work Behavior With Explicit And Implicit Measures Of Conscientiousness, Agreeableness, And Emotional Stability, Jimmy Zheng May 2019

Predicting Counterproductive Work Behavior With Explicit And Implicit Measures Of Conscientiousness, Agreeableness, And Emotional Stability, Jimmy Zheng

Electronic Theses and Dissertations

The current study leveraged the stressor-emotion model of CWB, the reflective-impulsive model of behavior, and theories of explicit and implicit personality to investigate the roles explicit and implicit aspects of personality, and work stressors have in influencing CWB. The stressor-emotion and reflective-impulsive models suggest that in addition to reflective (i.e., explicit) processes, impulsive (i.e., implicit) processes may also influence CWB because the act can be motivated by negative emotions induced by frustrating working conditions. Theories of personality and motivation suggest that conscientiousness, agreeableness, and emotional stability predict CWB because these traits motivate people to pursue goals that reduce ...


The Path Of A Stressed Temporary Worker To Cwb, Jamie Striler Jan 2019

The Path Of A Stressed Temporary Worker To Cwb, Jamie Striler

Electronic Theses and Dissertations

Temporary workers may experience unique and oftentimes stressful work situations that can precipitate negative outcomes for these workers, their coworkers, and their organizations. The current study considered broader implications of the various work experiences among temporary workers by testing the relationships of workplace stressors to temporary workers' behaviors. The workplace stressors examined were chosen based on their salience to temporary workers as shown throughout the current temporary worker literature, and included economic stressors, interpersonal mistreatment, and organizational constraints. It was hypothesized that these stressors would predict temporary workers' behaviors via emotional exhaustion and moral disengagement pathways, predicting the performance of ...


Subjective Measures Of Implicit Categorization Learning, Audrey Zlatkin Jan 2019

Subjective Measures Of Implicit Categorization Learning, Audrey Zlatkin

Electronic Theses and Dissertations

The neuropsychological theory known as COVIS (COmpetition between Verbal and Implicit Systems) postulates that distinct brain systems compete during category learning. The explicit system involves conscious hypothesis testing about verbalizable rules, while the implicit system relies on procedural learning of rules that are difficult to verbalize. Specifically from a behavioral approach, COVIS has been supported through demonstrating empirical dissociations between explicit and implicit learning tasks. The current studies were designed to gain deeper understanding of implicit category learning through the implementation of a subjective measure of awareness, Meta d', which until now has not been validated within a COVIS framework ...


Telephone-Delivered Cognitive Behavioral Therapy For Insomnia In Patients With Cancer: A Randomized Controlled Trial, Andel Nicasio Jan 2019

Telephone-Delivered Cognitive Behavioral Therapy For Insomnia In Patients With Cancer: A Randomized Controlled Trial, Andel Nicasio

Electronic Theses and Dissertations

This study examined the efficacy and feasibility of a brief telephone-delivered CBT-I (TeleCBT-I) intervention in cancer patients compared to a control group. The study used a randomized controlled trial design. The TeleCBT-I program consisted of a brief four-week CBT-I program adapted for cancer patients. Patients completed assessment measures at pre-treatment, post-treatment and one-month follow-up. Out of 184 patients screened, 39 were randomly assigned, and 35 (TeleCBT-I, n = 19; Control, n = 16) completed pre- and post-treatment measures and were included in the analyses. Compared to control group, the TeleCBT-I group reported decreased insomnia severity symptoms (p < .014), improved sleep quality (p < .023), and reduced dysfunctional beliefs about sleep (p = .039) at post-treatment with sustained treatment effects at one-month follow-up. Sleep measures yielded large effect sizes (Hedges' g, 0.84-2.7). Although the TeleCBT-I group indicated improvements in fatigue, general functioning, physical well-being, functional well-being, and physical quality of life, effects at follow-up were observed only for fatigue, functional well-being and physical quality of life. No effects were found on depression at any of the time points. In terms of feasibility, TeleCBT-I demonstrated high adherence, high homework completion and high overall satisfaction. These results advance the empirical evidence of CBT-I in cancer patients and support the use of telephone-delivered CBT-I to widely disseminate and implement among patients with cancer.


Habituation Trajectory During Exposure Therapy: Comparing Trauma Frequency And Trauma Type, Madeline Marks Jan 2019

Habituation Trajectory During Exposure Therapy: Comparing Trauma Frequency And Trauma Type, Madeline Marks

Electronic Theses and Dissertations

The current DSM-5 criteria for Posttraumatic Stress Disorder (PTSD) affords heterogeneous symptom presentations; however, current treatment fails to consider differences in trauma frequency and trauma type. These different symptom profiles that exist within the PTSD framework lead to questions about the generalizability of treatment outcomes from one group to another group. One group of interest is those that experience multiple traumatic events and report multiple index traumas (trauma frequency). The second group of interest is those with a PTSD diagnosis from occupational exposure to traumatic events (trauma type). Appreciation of the reinforcement schedule may be particularly crucial for understanding treatment ...


The Role Of Resilience On Second-Victim Outcomes: Examining Individual And External Factors Of Medical Professionals, Claudia Hernandez Jan 2019

The Role Of Resilience On Second-Victim Outcomes: Examining Individual And External Factors Of Medical Professionals, Claudia Hernandez

Electronic Theses and Dissertations

The present work is intended to bring awareness to medical professionals impacted by the occurrence of errors they have committed or witnessed (i.e., second-victims) and highlight the negative effects that may result from such errors. The purpose of this research is to test whether resilience and negative affect that is experienced after a medical error are related. Additionally, four variables are tested as moderators of this relationship, two of which are considered individual variables (i.e., self-efficacy and work meaningfulness), and two of which are characterized as external variables (i.e., co-worker support and organizational support). Twenty-two healthcare professionals ...


Brief Behavioral Health Intervention Program For Patients With Stable Coronary Artery Disease, Chelsea Wiener Jan 2019

Brief Behavioral Health Intervention Program For Patients With Stable Coronary Artery Disease, Chelsea Wiener

Electronic Theses and Dissertations

Healthy eating, physical activity, stress management, and smoking cessation are widely recognized as essential for preventing and treating coronary artery disease (CAD). Research on lifestyle programs for patients with CAD has largely focused on long-term interventions (e.g., several months to one-year in duration). Further, many studies have recruited patients immediately post-cardiac event. By contrast, evaluation of brief lifestyle interventions for stable patients treated in outpatient cardiology is lacking. The present study evaluated the feasibility, acceptability, and efficacy of a 3-session behavioral health lifestyle program for patients with stable CAD being treated in an outpatient cardiology clinic. Thirty-three patients were ...


Cognitive And Vascular Risk Factors For Depression: Testing An Integrated Theoretical Framework, Rosanna Scott Jan 2019

Cognitive And Vascular Risk Factors For Depression: Testing An Integrated Theoretical Framework, Rosanna Scott

Electronic Theses and Dissertations

Objective: Theoretical models that have guided the study of later-life depression include the vascular depression hypothesis, depression-executive dysfunction syndrome, and the CaR-FA-X model. Evidence suggests these can be integrated into a single developmental model of disordered mood (and its associated overgeneral memory feature) in later-life to delineate a mechanism of the vascular depression effect and identify modifiable intervention targets. Methods: In older adults, four serial mediation models evaluated the relationships between (1) vascular burden and depressive symptoms via executive control and rumination, and (2) vascular burden and autobiographical memory specificity (AMS) via executive control and rumination. In younger adults, four ...


The Creation And Validation Of A Compromising Scale For Nurses, Matthew Ng Jan 2019

The Creation And Validation Of A Compromising Scale For Nurses, Matthew Ng

Electronic Theses and Dissertations

For reasons such as job context and different interactions, compromising as performed by nurses is likely fundamentally different than compromising performed by other occupations. The following study proposes the creation and validation of a compromising scale for nurses. The first study aims to create the compromising scale for nurses through contemporary methods then test the reliability as well as the factor structure using an exploratory factor analysis on currently employed nurses recruited through a Qualtrics panel study. The second study then takes the final compromising scale for nurses and conducts a confirmatory factor analysis among a sample of employed nurses ...


Neurological Reactivity To Personalized Odors And Sounds In Combat-Related Posttraumatic Stress Disorder, Michael Gramlich Jan 2019

Neurological Reactivity To Personalized Odors And Sounds In Combat-Related Posttraumatic Stress Disorder, Michael Gramlich

Electronic Theses and Dissertations

Functional near-infrared spectroscopy (fNIRS) is a neurophysiological procedure that offers immense clinical utility due to its cost effectiveness, ease of use, and mobile application. Using fNIRS to measure neurological reactions to personalized trauma-related cues might strengthen diagnostic screening, tailor treatment planning, and improve detection of remission among individuals with posttraumatic stress disorder (PTSD). Odors elicit strong emotional responses but remain underutilized in clinical research. This fNIRS study examined whether personalizing combat-related odors and sounds to have a higher or lower match to distressing combat experiences increased the observed neurological effect among combat veterans with and without combat-related PTSD. This study ...


Designing Calorie Counter Smartphone Applications For Effective Weight Loss, Sharlin Milliard Jan 2019

Designing Calorie Counter Smartphone Applications For Effective Weight Loss, Sharlin Milliard

Electronic Theses and Dissertations

Poor dietary choices and lack of physical activity are two main contributing factors for the increasing prevalence of overweight and obesity in the United States. Overweight and obese individuals are at risk for developing major life-threatening diseases. Weight loss is an effective means for reversing these adverse health effects, and smartphone applications (apps) may be an effective means for supporting weight loss outside of formal clinical settings. This study involved identifying factors that contribute to effective weight loss to compare with functionality commonly found in a sample of calorie counter apps. A content analysis was performed using a design framework ...


The Effects Of Presence And Cognitive Load On Episodic Memory In Virtual Environments, Paul Barclay Jan 2019

The Effects Of Presence And Cognitive Load On Episodic Memory In Virtual Environments, Paul Barclay

Electronic Theses and Dissertations

Episodic memory refers to an individual's memory for events that they have experienced in the past along with the associated contextual details. In order to more closely reflect the way that episodic memory functions in the real world, researchers and clinicians test episodic memory using virtual environments. However, these virtual environments introduce new interfaces and task demands that are not present in traditional methodologies. This dissertation investigates these environments through the lenses of Presence and Cognitive Load theories in order to unravel the ways that basic technological and task differences may affect memory performance. Participants completed a virtual task ...


Protective Behavioral Strategies And Alcohol-Related Sex Among College Students, Roselyn Peterson Jan 2019

Protective Behavioral Strategies And Alcohol-Related Sex Among College Students, Roselyn Peterson

Electronic Theses and Dissertations

Adverse sexual outcomes (e.g., sexual regret, sexual risk, and sexual assault) are a common experience among college students. In particular, regretted sex is reported by a third of college students and may result in psychological harm. Previous literature has found that alcohol is involved in approximately one third of regretted sex experienced by college students. A gap exists in the literature identifying who is more susceptible to experiencing a regretted sexual experience. Previous research has shown that students who implement protective behavioral strategies (PBS) while drinking are able to reduce alcohol-related negative consequences, including regretted sexual experiences. Three sub-types ...


Predictors Of Territorial Work Behavior: An Investigation Of Individual Differences In Personality Using The Hexaco Model, Andrew White Jan 2019

Predictors Of Territorial Work Behavior: An Investigation Of Individual Differences In Personality Using The Hexaco Model, Andrew White

Electronic Theses and Dissertations

To date, little research has examined the relationship between territorial work behavior and individual differences in personality. Using hierarchical multiple regression, dimension-level and facet-level personality traits of the HEXACO model of personality were examined to determine whether personality traits predict territorial work behaviors. Based on a sample of 160 workers from Amazon's Mechanical Turk, it was observed that the dimensions of Honesty-Humility, Emotionality, Openness to Experience, and Altruism predicted territorial work behaviors. In addition, facet-level traits from these dimensions, in addition to facets from the Extraversion and Agreeableness dimension, explained variance in each of the territorial behaviors. Furthermore, quantile ...


The Efficacy Of A 6-Week Evidence-Based Support Group For Caregivers Of Dementia In A Primary Care Setting, Mona Shah Jan 2018

The Efficacy Of A 6-Week Evidence-Based Support Group For Caregivers Of Dementia In A Primary Care Setting, Mona Shah

Electronic Theses and Dissertations

More than 16 million Americans provide unpaid care for those with Alzheimer's disease and other dementias. Extant literature has well documented the increased risk for physical, emotional, social and financial burden associated with caregiving. While intensive support groups may be well-suited to caregiver needs, they are often difficult to implement given financial, personnel and resource constraints. Thus, the purpose of this study is to examine the efficacy of a theoretically-based, 6-week caregiver support group in a community primary care setting. The group focuses on self-care, behavior management techniques and interdisciplinary caregiver resources. A total of 22 participants completed the ...


The Relationship Between Team Role Sub-Dimensions, Personality, And Team Effectiveness, Ryan Howell Jan 2018

The Relationship Between Team Role Sub-Dimensions, Personality, And Team Effectiveness, Ryan Howell

Electronic Theses and Dissertations

A manned mission to Mars would be the longest manned mission (both by distance and duration) to date by a considerable margin. Such a mission poses a unique set of challenges to astronaut teams, including extreme levels of isolation and confinement never before experienced by Earth-bound teams. A crucial step in ensuring the team will arrive back on Earth safely is selecting those individuals who are most apt for the job. To facilitate the selection process and development of countermeasures, this work (as part of a larger NASA research grant) involves examining the relationship between personality (Big 5; openness, conscientiousness ...


Young Adult Development And Caregiving: Disposition And Involvement In Care, Nicholas James Jan 2018

Young Adult Development And Caregiving: Disposition And Involvement In Care, Nicholas James

Electronic Theses and Dissertations

Caregivers are a diverse group of individuals with a variety of backgrounds and roles; however, research has widely overlooked young adults in this population. This study investigated young adult caregiver circumstance, burden, and use of support services with the purpose of improving future caregiving research and interventions. Study 1 compared burden and circumstance among young, middle aged, and older adult caregivers (N = 285) in addition to developmental indicators among young adults caregiver and demographically matched non-caregiver peers (n = 225). Study 2 surveyed caregivers from each age group (N = 151) on barriers to care, treatment preferences, and interest in services. Results ...


Working Memory Capacity And Executive Attention As Predictors Of Distracted Driving, Jennifer Louie Jan 2018

Working Memory Capacity And Executive Attention As Predictors Of Distracted Driving, Jennifer Louie

Electronic Theses and Dissertations

The present study empirically examined the effects of working memory capacity (WMC) and executive attention on distracted driving. Study 1 examined whether a Grocery List Task (GLT) distractor would load onto WMC. Forty-three participants completed a series of WMC tasks followed by the GLT. They then completed two driving trials: driving without the GLT and driving while completing the GLT. It was hypothesized that WMC would positively correlate with GLT performance. A bivariate correlation indicated that WMC was positively associated with performance on the GLT. Study 2 tested a series of distractor tasks (GLT, Tone Monitoring, and Stop Signal) to ...


Examining Followership Role Orientation, Douglas Monsky Jan 2018

Examining Followership Role Orientation, Douglas Monsky

Electronic Theses and Dissertations

This study attempts to make steps toward filling significant gaps in the followership literature. The study of followership has often been seen through the lens of leaders' ability to impart change in follower behavior. In doing so, the literature has primarily focused on leader behavior as the agent of change rather than acknowledging followers as active agents in their own behaviors. However, some recent research has shown the emergence of followers as the primary focus, even looking at how their actions can change the way leaders act. This research focuses primarily on followership role orientations as mental models which specify ...


Alcohol Pathology And The Triarchic Model Of Psychopathy: The Role Of Protective Behavioral Strategies And Impulsivity, Matthew Kramer Jan 2018

Alcohol Pathology And The Triarchic Model Of Psychopathy: The Role Of Protective Behavioral Strategies And Impulsivity, Matthew Kramer

Electronic Theses and Dissertations

OVERVIEW: Psychopathy has been an area of growing interest in psychology for the last half century. Currently, the most common conceptualization of psychopathy breaks it down into two factors: primary and secondary psychopathy. More recently, psychopathy has been viewed through a more nuanced model, the Triarchic Model of Psychopathy. The present study examines the relationship between the three facets of the Triarchic Model and alcohol pathology via aspects of impulsivity and Protective Behavioral Strategies (PBS). METHOD: A college student sample of n = 967 individuals who endorsed consuming alcohol completed surveys regarding the Triarchic Model, impulsivity, PBS use, and alcohol pathology ...


Dissecting The Components Of Neuropathic Pain, Dale George Jan 2018

Dissecting The Components Of Neuropathic Pain, Dale George

Electronic Theses and Dissertations

Pain is a public health issue affecting the lives of nearly 116 million adults in the US, annually. Understanding the physiological and phenotypic changes that occur in response to painful stimuli is of tremendous clinical interest, but, the complexity of pain and the lack of a representative in vitro model hinders the development of new therapeutics. Pain stimuli are first perceived and transmitted by the neurons within the dorsal root ganglia (DRG) which become hyperexcitable under these conditions. It has now been established that satellite glial cells (SGCs) that ensheathe the DRG cell body actively contribute to this neuronal dysregulation ...


Subjective-Objective Discrepancies Among Patients With Sleep Complaints In The Patient-Centered Medical Home, Keri Bayley Jan 2018

Subjective-Objective Discrepancies Among Patients With Sleep Complaints In The Patient-Centered Medical Home, Keri Bayley

Electronic Theses and Dissertations

Sleep misperception – the discrepancy between objective and subjective measures of sleep – has been shown to be prevalent among patients with insomnia and may be a promising target for sleep intervention. This study examined sleep misperception in a diverse outpatient medical sample using consumer-grade wearable actigraphs (i.e., Fitbit Charge HR™). Forty-four self-identified problem sleepers aged 20 to 79 participated in the study. Participants completed sleep diaries for one week while also tracking their sleep using the Fitbit Charge HR™. After receiving a personalized sleep report based on these data, participants repeated another week of sleep assessment. Sleep misperception was observed ...


Adaptation And Resilience Of Extreme Teams: A Qualitative Study Using Historiometric Analysis, Lauren Campbell Jan 2018

Adaptation And Resilience Of Extreme Teams: A Qualitative Study Using Historiometric Analysis, Lauren Campbell

Electronic Theses and Dissertations

The business and academic worlds agree that team resilience and team adaptation are in increasing need of study. This study explores the behavioral processes of team adaptation—specifically, those action phase and interpersonal processes mapped by Marks, Mathieu, and Zaccaro (2001) and overlapping with the team adaptation model by Burke, Stagl, Salas, Pierce, and Kendall (2006) and expanded by Rosen et al. (2011). Additionally, the impact of trigger type on adaptive behaviors is explored as suggested by Maynard and Kennedy (2016). These explorations are conducted within the context of extreme teams, and the primary method used is Crayne and Hunter ...


Olfaction, Memory, And Presence In Warfighters: Do The Scents Of War Matter?, Benson Munyan Jan 2018

Olfaction, Memory, And Presence In Warfighters: Do The Scents Of War Matter?, Benson Munyan

Electronic Theses and Dissertations

Background: Exposure therapy (EXP) is a first-line intervention for combat-related PTSD. EXP works by repeatedly exposing the patient to the feared stimuli, situation, or physical sensations in the absence of actual danger until the stimuli no longer evoke maladaptive responses. Over the past decade, multiple technologies have been introduced to augment the EXP process by presenting multi-sensory cues (e.g., sights, smells, sounds) to increase patients' sense of presence. Exploratory research has only broadly examined the effect of odorants on the patient's sense of presence during simulated exposure tasks. This study hypothesized that those with autobiographical memories similar to ...


Rumination And Executive Dysfunction: Risk Factors For Vascular Depression, David Brush Jan 2018

Rumination And Executive Dysfunction: Risk Factors For Vascular Depression, David Brush

Electronic Theses and Dissertations

Introduction: The widely-supported vascular depression hypothesis is underspecified with respect to cognitive mechanisms by which high cerebrovascular burden (CVB) and neuropathology relate to depressive symptoms. Integration of the vascular depression hypothesis with the CaR-FA-X model, a framework of affect regulation mechanisms, suggest that Rumination (R) and executive dysfunction (X) may increase due to altered recruitment of the dorsolateral prefrontal cortex resulting from high CVB and underlying neuropathology. This process would contribute to depressive symptomatology among older adults with high CVB. The progression of examined hypotheses included mediation models examining mechanistic relationships between predictors (CVB, DLPFC activation), cognitive correlates (rumination, executive ...


Childhood Experiences And Domestic Violence: The Role That Interpartner Violence Plays In Relationship Functioning And Parenting Behaviors In Adulthood., J'Nelle Stephenson Jan 2018

Childhood Experiences And Domestic Violence: The Role That Interpartner Violence Plays In Relationship Functioning And Parenting Behaviors In Adulthood., J'Nelle Stephenson

Electronic Theses and Dissertations

It is estimated that approximately 25% of women and 7.6% of men report experiencing violence from their romantic partner during their lifetime. Additionally, in households where interpartner violence occurs, there are between 3.3 and 10 million children in the United States alone. It is important to understand the cycle of domestic violence that can occur, as it can inform us about expected outcomes across time. This study examined mothers' childhood exposure to their own parents' domestic violence. It was hypothesized that childhood exposure to domestic violence would be related to unhealthy intimate relationships and to the development of ...


Potential Relationship Between Vascular Depression And Autobiographical Memory Specificity In An Older Adult Population According To The Car-Fa-X Model, Manuel Herrera Legon Jan 2018

Potential Relationship Between Vascular Depression And Autobiographical Memory Specificity In An Older Adult Population According To The Car-Fa-X Model, Manuel Herrera Legon

Electronic Theses and Dissertations

Vascular depression is a type of depression that has its onset later in life, and it has been associated with cardiovascular or metabolic diseases. Depression can be costly and associated with other health problems, which is why it becomes imperative to uncover the multiple mechanisms of action for depression symptomatology. A proposed mechanism of action for the emergence of depressive symptomatology is poor autobiographical memory specificity according to the CaR-FA-X model. However, it remains unclear whether this mechanism contributes somehow to the vascular depression specific type. The purpose of this research was to determine the potential relationship between the mechanisms ...
