Examining The Role Of Stress In Binge Eating Disorder, Stephanie M. Lamattina

Electronic Theses and Dissertations

[In lieu of Abstract, excerpt from Conclusion of Examining the Role of Stress in Binge Eating Disorder]:

Results from the present study support growing evidence which demonstrates that stress can negatively impact binge eating. However, given the paucity of research examining these variables in clinical samples of individuals diagnosed with BED, additional research is warranted. Therefore, future studies should continue to recruit clinical samples utilizing clinical interviews. Research is also needed to further explore the relationship between cortisol and binge eating in individuals diagnosed with BED. Interestingly, individuals diagnosed with BED perceived the stress task (and situations in general) …

Dismantling An Act-Based Intervention For Work Stress: Do Values Really Matter?, Barbara A. Hermann

Electronic Theses and Dissertations

Acceptance and Commitment Therapy (ACT), a multi-component intervention within the third-wave of behavioral therapy, has been shown to improve various outcomes in diverse populations and administration formats. This study utilized a dismantling design to investigate whether the values components of an ACT-based intervention for work stress add to the effects of the intervention beyond those of the mindfulness components and to explore possible mediators of change. Expanding beyond existing studies of ACT, a broad range of outcomes were examined pretreatment, post-treatment, and at three follow-up assessments in a small sample (N = 16) of employees of a university in the …

Role Of Perceived Partner Responsiveness On Mexican American Males' Pain Severity And Depressive Symptomatology, Carolyn M. Freedman

Electronic Theses and Dissertations

This study examined the role of cultural indicators in moderating the influence of perceived partner responses and relationship satisfaction on pain severity and depressive symptomatology among a sample of 62 married and cohabiting Mexican American men, the majority of whom were first generation Mexican Americans, with chronic back and/or neck pain. The cultural indicators were not found to act as moderators in the analyses that involved pain severity and depressive symptomatology as outcome variables. Nevertheless, this study's findings are an important initial step in understanding the relationship dynamics among an understudied population with chronic pain and raise many important questions …

Resisting And Transforming: Pastoral Theology And Care Of Korean Military Wives, Bocheol Chang

Electronic Theses and Dissertations

Korean military wives have been symbolized as "dirty," "nothing," and "evil" by Koreans, Korean Americans, and their American families. They also experience same level of oppression and discrimination within Korean American congregations. In Korea, the women suffered poverty, sexual violence, and Confucian gender discrimination. They have also experienced racial and sexual oppression, intercultural familial conflicts and violence, and identity crisis in America. All of those experiences are caused the sense of not belonging of Korean military wives.

The sense of not belonging and desperation can be explained well by Andrew Sung Park's theology of han. The theology of han …

Self-Esteem In Relation To Casual Sex Behavior, Attitudes, And Affect., Kathryn Bieda

Electronic Theses and Dissertations

Casual sex is common on college campuses and is potentially relevant to a person's self-esteem. Unfortunately, data are mixed regarding how self-esteem is influenced by casual sex. This thesis is an attempt to understand how casual sex influences women's self-esteem through a series of questionnaires. Three hypotheses were of interest. The first predicted that sociosexuality and desire would explain casual sex engagement. Second, that casual sex behaviors and attitudes would predict self-esteem. Third, looking only at those who engaged in casual sex; casual sex attitudes and affect would predict self-esteem. Using hierarchical regression, results indicated that there was a curvilinear …

College Student Vulnerability To Harmful Religious Groups Based On Perceptions., Kevin Clark Dreher

Electronic Theses and Dissertations

This study was conducted in an attempt to understand which, if any, groups of college students are susceptible to cult influence based on false perceptions. Religion is a powerful practice that, if used for the wrong reasons, can influence a person to dissolve social and financial relationships with family, friends, and the surrounding community. Surveys were given to randomly selected cluster samples of students currently enrolled at the university. These surveys consisted of demographic questions and a scale designed to measure perceptions. Also devised was a scale to measure traits of depression. Both bivariate and multivariate analysis showed that the …

Disappointment Domains, Quality Of Life, And The Impact Of Mental Illness : An Evaluation Of Demographic Differences., Christina Lynn Adkins

Electronic Theses and Dissertations

The concept of quality of life (QOL) has been the topic of many research projects, yet several clinically relevant aspects of this concept have been overlooked. Specifically, few studies have addressed the impact of such demographic variables as race and sex on the life domains that have been particularly disappointing to patients with mental illnesses. The current research project aims to contribute to the understanding of the impact these variables have on quality of life, specifically addressing the following hypotheses: (1) Domains of disappointment will vary according to race and sex; (2) Race and sex will interact to predict which …

Predicting Behavior From Psychopathic And Antisocial Personality Traits In A Student Sample., Maryann Stone

Electronic Theses and Dissertations

Psychopathic personality is associated with a myriad of social and behavioral problems including violence, criminal activity, and overall failure to conform to social standards. In this study, psychopathic and antisocial personality traits are measured in a sample of college students via self-report surveys using questions derived from Hare's Psychopathic Checklist-Revised (PCL-R; 1991). Reliability and factor analyses were used to validate the inventory and create factor-based indices that were used to predict antisocial behavioral outcomes including violence, seeking revenge on persecutors, and suicidal ideation, in addition to other analogous and deviant behaviors. Findings showed a relationship between personality and behavior indicating …

Characteristics For Success: Predicting Intervention Effectiveness With The Job Characteristics Model, Sallie Weaver

Electronic Theses and Dissertations

The current study examines the effects of the five core job characteristics (skill variety, task significance, task identity, autonomy, and feedback) proposed by Hackman-Oldham (1974) at the team level by investigating whether the model variables are related to the effectiveness of a motivationally-based team-level productivity enhancement intervention. Previous literature has almost exclusively focused on the effects of these job characteristics at the individual level and their direct relationships with employee attitudes and subjective measures of performance. This thesis aims to further the job characteristics literature by exploring the effects of the characteristics at the team level, as well as the …

You Scratch My Back And I'Ll Scratch Yours: Mentor-Perceived Costs And Benefits And The Functions They Provide Their Proteges, Julia Fullick

Electronic Theses and Dissertations

Mentoring relationships can have both costs and benefits for mentors and their proteges. The present research examined the degree to which mentors' perceived costs and benefits affect the functional and dysfunctional mentoring they provide to their proteges. Additionally, I investigated whether mentor-perceived costs and benefits were associated with the mentors' own goal orientation and the goal orientation of their proteges. Data were collected from 86 proteges and their current supervisory mentors. Consistent with expectations, when mentors reported greater costs of embarrassment associated with their relationship, the proteges reported receiving greater dysfunctional mentoring. Proteges who reported receiving greater functional mentoring tended …

Field Of View Effects On Reflexive Motor Response In Flight Simulation, Javier Covelli

Electronic Theses and Dissertations

Virtual Reality (VR) and Augmented Reality (AR) Head Mounted Display (HMD) or Head Worn Display (HWD) technology represents low-cost, wide Field of Regard (FOR), deployable systems when compared to traditional simulation facilities. However, given current technological limitations, HWD flight simulator implementations provide a limited effective Field of View (eFOV) far narrower than the normal human 200[degrees] horizontal and 135[degrees] vertical FOV. Developing a HWD with such a wide FOV is expensive but can increase the aviator's visual stimulus, perception, sense of presence and overall training effectiveness. This research and experimentation test this proposition by manipulating the eFOV of experienced pilots …

Hyperactivity In Boys With Attention-Deficit/Hyperactivity Disorder: A Ubiquitous Core Symptom Or Manifestation Of Working Memor, Jennifer Bolden

Electronic Theses and Dissertations

Hyperactivity is currently considered a core and ubiquitous feature of attention-deficit/hyperactivity disorder (ADHD); however, an alternative model challenges this premise and hypothesizes a functional relationship between working memory (WM) and activity level. The current study investigated whether children s activity level is functionally related to WM demands associated with the domain-general central executive and subsidiary storage/rehearsal components using tasks based on Baddeley s (2007) WM model. Activity level was objectively measured 16 times per second using wrist- and ankle-worn actigraphs while 23 boys between 8 and 12 years of age completed control tasks and visuospatial/phonological WM tasks of increasing memory …

Gamma Hydroxybutyrate Use Among College Students: Application Of A Memory Model To Explore The Influence Of Outcome Expectancies, Pamela Brown

Electronic Theses and Dissertations

Gamma Hydroxybutyrate (GHB) was banned from the consumer market by the Food and Drug Administration in 1991. Despite the ban, use of GHB has continued to contribute to thousands of emergency department visits and numerous fatalities in recent years. Efforts to reduce the use of this drug have had limited impact, which may be the result of using traditional prevention strategies that focus exclusively on educating people about of negative consequences of substance use rather than addressing the factors that motivate use. In an effort to identify motivational factors that could be targeted in future prevention efforts, the present study …

Hysteresis Effects In Driving, Justin Morgan

Electronic Theses and Dissertations

This dissertation presents two studies examining the interaction between workload history and driver mental workload. The first experiment focuses on testing for the presence of a hysteresis effect in the driving task. The second experiment examines the proposition that cueing impending periods of higher task demand can reduce the impact of any such potential hysteresis effects. Thirty-two licensed drivers served as participants and all served in both studies. Using the directions provided by a Heads-Up-Display navigation system, participants followed a pre-set route in the simulated environment. At specified points within the drive, the navigation system would purposefully fail which required …

Tactile Working Memory And Multimodal Loading, Peter Terrence

Electronic Theses and Dissertations

This work explored the role of spatial grouping, set size, and stimulus probe modality using a recall task for visual, auditory, and tactile information. The effects of different working memory (WM) loading task modalities were also examined. The Gestalt spatial organizing principle of grouping showed improvements in response times for visual and tactile stimulus probes with large set sizes and apparently allowed participants to effectively chunk the information. This research suggests that tactile information may use spatial characteristics typically associated with visual information, as well as sequential characteristics normally associated with verbal information. Based on these results, a reformulation of …

Multimedia Computer-Based Training And Learning: The Role Of Referential Connections In Supporting Cognitive Learning Outcomes, Sandro Scielzo

Electronic Theses and Dissertations

Multimedia theory has generated a number of principles and guidelines to support computer-based training (CBT) design. However, the cognitive processes responsible for learning, from which these principles and guidelines stem from, are only indirectly derived by focusing on cognitive learning outcome differences. Unfortunately, the effects that cognitive processes have on learning are based on the assumption that cognitive learning outcomes are indicative of certain cognitive processes. Such circular reasoning is what prompted this dissertation. Specifically, this dissertation looked at the notion of referential connections, which is a prevalent cognitive process that is thought to support knowledge acquisition in a multimedia …

Using A Contingency-Based Method For Combining Individual Assessment Center Dimension Ratings Into Overall Assessment Ratings, Keisha Wicks

Electronic Theses and Dissertations

The current study applies a newly proposed mechanical combination method along with four traditional mechanical combination methods to assessment center scoring. These comparisons were made for two job levels (Fire Lieutenant and Fire Captain). The study further assesses the level of adverse impact for the various methods at three cut-off scores. Results indicated that the new contingency-based scoring method was successfully implemented in the assessment center. Results were mixed regarding whether the contingencies developed for the two job levels were different. Further, results indicated that although the various combination methods were highly correlated as expected, there were clear distinctions in …

Investigating The Effects Of Tactile Stress On A Military Touniquet Application Task, Razia Nayeem

Electronic Theses and Dissertations

In combat, soldiers encounter stress from multiple sources including loss of sleep, extremely high levels of physical and psychological discomfort, extended periods of increased vigilance, and intense danger. Therefore, it is imperative to train such personnel on how to cope with these stressors. One way to do this is to include stressors in different forms of training to acclimate soldiers to the subsequent stress of combat. Due to their advantages, tactile trainers are being investigated increasingly for the use of training Army medics in this context. The present work examines how vibrating tactile sensors, or tactors, can be used as …

Adhd And Stop-Signal Behavioral Inhibition: Is Mean Reaction Time Contaminated By Exposure To Intermittent Stop-Signals?, Robert Alderson

Electronic Theses and Dissertations

The current study investigates two recently identified threats to the construct validity of behavioral inhibition as a core deficit of attention-deficit/hyperactivity disorder (ADHD) based on the Stop-signal task: calculation of mean reaction time from go-trials presented adjacent to intermittent stop-trials, and non-reporting of the stop-signal delay metric. Children with ADHD (n=12) and typically developing children (TD) (n=11) were administered the standard stop-signal task and three variant stop-signal conditions. These included a No-Tone condition administered without the presentation of an auditory tone; an Ignore-Tone condition that presented a neutral (i.e., not associated with stopping) auditory tone; and a second Ignore-Tone condition …

The Effects Of Training On Goal Orientation, Mentoring Relationship Processes, And Outcomes, Shannon Scielzo

Electronic Theses and Dissertations

The purpose of the current study was to examine the effectiveness of preparatory training for mentors and proteges with respect to relationship processes and outcomes. Specifically, it was proposed that training provided to mentors and their proteges should foster a high learning goal orientation and a low avoid goal orientation. The former is associated with learning for the sake of continuous improvement and the latter is associated with a willingness to be perceived by others as having failed at a task. It was hypothesized that mentors and proteges who received goal orientation training prior to beginning their formal mentoring sessions …

Feedback-Based Alcohol Interventions For Mandated Students: A Comparison Of Individual, Group, And Electronic Formats, Jacqueline Alfonso

Electronic Theses and Dissertations

The present study examined the effectiveness of personalized alcohol feedback interventions in three different delivery formats on alcohol use and related negative consequences in a sample of mandated college students referred for alcohol-related violations. Participants were randomized to one of three conditions: an individually-delivered face-to-face intervention, a group-delivered face-to-face intervention, or a web-based electronically-delivered intervention. Given that the current study sought to modify factors associated with alcohol use, analyses were conducted using only those participants who reported alcohol use at the baseline assessment. The final sample resulted in 173 participants, 18-years-of-age and over, and consisted of 57% males (n = …

Work-Family Conflict And Performance Evaluations: Who Gets A Break?, Kara Hickson

Electronic Theses and Dissertations

Forty percent of employed parents report that they experience work-family conflict (Galinsky, Bond, & Friedman, 1993). Work-family conflict (WFC) exists when role pressures from the work and family domains are mutually incompatible. WFC is associated with decreases in family, job, and life satisfaction and physical health; intention to quit one's job; and increases in workplace absenteeism. Women may be more impacted by WFC than men, as women report completing 65-80% of the child care (Sayer, 2001) and spend 80 hours per week fulfilling work and home responsibilities (Cowan, 1983). Research suggests that WFC can be reduced with social support, such …

The Influence Of Cultural Diversity On Initial Decisions To Trust In Newly Forming Teams: A Policy Capturing Approach, Heather Priest Walker

Electronic Theses and Dissertations

This study investigated the impact of diversity on the decision to trust at team formation when no history or prior relationship exists. The study consisted of two phases: 1) a selection phase and 2) a policy capturing phase. The first phase consisted of demographics, propensity to trust, and prejudice scales that were used to select participants for phase 2. The second phase consisted of a full factorial design, policy capturing study which consisted of 64 scenarios which varied the level (i.e., high and low) of 6 variables: cultural diversity, attribution, perceptions of risk, trustworthiness, third party information, and role clarity. …

The Relationships Between Leader Behavior, Follower Motivation, And Performance, Melissa Harrell

Electronic Theses and Dissertations

The primary goal of this study was to examine ways in which leaders can influence followers motivation. Motivation is a key construct in industrial and organizational psychology due to its impact on employee performance. Modern motivation theories adapt a more sophisticated view of motivation in terms of definition, relationships, and operationalization. In particular, one new theory of motivation is the Pritchard and Ashwood Theory (2008). This theory proposes that motivation is comprised of four perceived relationships that, in combination, reflect the extent to which employees believe that their actions on the job will lead to need satisfaction. These four relationships …

Cross-Modal Effects In Tactile And Visual Signaling, James Merlo

Electronic Theses and Dissertations

Using a wearable tactile display three experiments were conducted in which tactile messages were created emulating five standard US Army and Marine arm and hand signals for the military commands, namely: "Attention", "Halt", "Rally", "Move Out", and "Nuclear Biological or Chemical event (NBC)". Response times and accuracy rates were collected for novices responding to visual and tactile representations of these messages, which were displayed either alone or together in congruent or incongruent combinations. Results indicated synergistic effects for concurrent, congruent message presentations showing superior response times when compared to individual presentations in either modality alone. This effect was mediated by …

Motorcycle Conspicuity: The Effects Of Age And Vehicular Daytime Running Lights, Lorenzo Torrez

Electronic Theses and Dissertations

Research has shown that riding a motorcycle can potentially be much more dangerous than operating a conventional vehicle. There are factors inherent in driving or riding a small two wheeled vehicle, such as a motorcycle, moped or even bicycle that can potentially decrease their ability to be seen or noticed by other drivers. This disadvantage is reflected in the disproportionate over-representation of injuries and/or fatalities incurred by this particular driving group. This creates a significant problem which deserves dedicated evaluation as to causative factors and/or influential variables. The following research was conducted with intentions to investigate the topic of motorcycle …

Trait Arousability And Its Impact On Adaptive Multimedia Training, Sae Schatz

Electronic Theses and Dissertations

Today's best intelligent, adaptive, multimedia trainers have shown excellent performance; however, their results still fall far-short of what good human tutors can achieve. The overarching thesis of this paper is that future intelligent, adaptive systems will be improved by taking into account relevant, consistent, and meaningful individual differences. Specifically, responding to individual differences among trainees will (a) form more accurate individual baselines within a training system, and (b) better inform system responses (so that they interpret and respond to observable data more appropriately). One variable to consider is trait arousability, which describes individual differences in sensitivity to stimuli. Individuals' arousability …

The Impact Of Organizational Politics On Mentoring Relationships, Nicholas Bencaz

Electronic Theses and Dissertations

Mentoring in the workplace has become an increasingly popular trend because of its touted success at addressing the career and social related needs of employees. While the majority of the research on mentoring has examined protege benefits, far fewer studies have examined the potential negative effects of mentoring. Moreover, little is known about the antecedents of negative mentoring experiences. A primary objective of the present study was to investigate relations between mentor and protege perceptions of organizational politics and reports of functional and dysfunctional mentoring. In addition, I examined the joint contribution of functional and dysfunctional mentoring to a number …

Food For Thought: The Relationship Between Thought Suppression And Weight Control, Rachel Peterson

Electronic Theses and Dissertations

The current study assessed the relationship between individuals' tendency to suppress thoughts, particularly related to food and body weight/shape, and outcomes such as weight loss maintenance and diet sabotaging experiences (e.g., binge eating). Community and university individuals (N = 347) who are or previously were overweight completed self-report measures of thought suppression, weight history, and eating behaviors. Suppression of specific thoughts about food/weight/shape was related to weight cycling, binge eating, and food cravings. Participants who believed thoughts of food lead to eating were more likely to attempt suppression of food-related thoughts. Results have implications for improving weight loss maintenance and …

Distributed Team Training: Effective Team Feedback, Kevin Oden

Electronic Theses and Dissertations

The United States Army currently uses after action reviews (AARs) to give personnel feedback on their performance. However, due to the growing use of geographically distributed teams, the traditional AAR, with participants and a moderator in the same room, is becoming difficult; therefore, distributed AARs are becoming a necessity. However, distributed AARs have not been thoroughly researched. To determine what type of distributed AARs would best facilitate team training in distributed Army operations, feedback media platforms must be compared. This research compared three types of AARs, which are no AAR, teleconference AAR, and teleconference AAR with visual feedback, to determine …
