Sleep-Wake Disorders And A Look At Insomnia Through Biological And Behavioral Perspectives, Mia Fontanarosa Apr 2017

Sleep-Wake Disorders And A Look At Insomnia Through Biological And Behavioral Perspectives, Mia Fontanarosa

The Review: A Journal of Undergraduate Student Research

Insomnia is defined by difficulties in falling asleep, maintaining sleep, and problems with early morning awakenings. Unfortunately, due to these symptoms daytime fatigue often follows. Daytime fatigue may have a severe impact on an individual’s day. Insomnia symptoms may not exist alone, however. Individuals who are diagnosed with insomnia have another disorder present as well. Often insomnia is paired with anxiety and mood disorders. Therefore, insomnia can be viewed through the biological and behavioral perspectives. Insomnia is a disorder that can be treated. The most common treatment would be cognitive behavioral therapy for insomnia, but treatment is not limited to …


Reconnecting The Mind And Body: A Pilot Study Of Developing Compassion For Persistent Pain, Sarah L. Parry Dr, Zoey Malpus Dr Apr 2017

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 …


Examination Of Neurocorrelates Of Mild Traumatic Brain Injury In Young Adults, Rachel J. Raucci Apr 2017

Examination Of Neurocorrelates Of Mild Traumatic Brain Injury In Young Adults, Rachel J. Raucci

Neuroscience Honors Papers

In recent years, there has been an upswing in the number of concussion diagnoses per year in the United States, particularly in young athletes with still-developing brains. Accompanying this recent trend is an increased amount of research on concussions and their long-term impacts. This ongoing research project collects and compares data from concussed and non-concussed individuals using various neuropsychological batteries, self-report surveys and participants’ EEG readings. Data analysis of the results from 51 participants indicates that previously concussed individuals differ from their non-concussed counterparts. Specifically, individuals who have suffered a concussion exhibit specific and occasionally idiosyncratic deficits in executive control …


The Phenomenon Of Teacher Burnout: Mitigating Its Influence On New Teachers, Kaila Sanford Apr 2017

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 …


The Relationship Between Promoting Self-Efficacy And Informed Decision-Making In Pregnant Nulliparous Women And Method Of Delivery, Crystal Hunter Apr 2017

The Relationship Between Promoting Self-Efficacy And Informed Decision-Making In Pregnant Nulliparous Women And Method Of Delivery, Crystal Hunter

Scholarly and Creative Works Conference (2015 - 2021)

This presentation will cover the relationship between the concepts of decreased self-efficacy in pregnant women’s abilities to deliver their babies vaginally, fear of the pain and duration of labor process, and the acceptance of medical intervention without sufficient intrapartum education surrounding delivery methods. These interrelated variables impede the concept of informed choice. The current state of the problem surrounds women with low self-efficacy who are predicted to have negative childbirth experiences such as, consenting to an astronomically high rate of cesarean sections. The focus for nursing is that low-risk, healthy women who elect cesarean sections without the knowledge that permanent …


An Analysis Of Positive Coping Mechanisms Utilized To Overcome Trauma In Post-Genocidal Rwanda, Danielle Marvin Apr 2017

An Analysis Of Positive Coping Mechanisms Utilized To Overcome Trauma In Post-Genocidal Rwanda, Danielle Marvin

Independent Study Project (ISP) Collection

From April 7th to July 1st of 1994, one million Rwandan people were brutally murdered by their friends and neighbors in the meticulously planned and government-sponsored Genocide against the Tutsi. Survivors witnessed killings and sexual assault, had their lives threatened, lost multiple family members, and hid under dead bodies to evade the killers. To make matters worse, trust within communities and even within families was destroyed as Hutu perpetrators turned against Tutsis they had, days earlier, been inviting to family events. After the genocide, PTSD rates among adults in Rwanda were estimated at 20.5% for men and 30% for women …

Temperament Factors And Dimensional, Latent Bifactor Models Of Child Psychopathology: Transdiagnostic And Specific Associations In Two Youth Samples, Benjamin L. Hankin, Elyssia Poggi Davis, Hannah Snyder, Jami F. Young, Laura M. Glynn, Curt A. Sandman

Psychology Faculty Articles and Research

Common emotional and behavioral symptoms co-occur and are associated with core temperament factors. This study investigated links between temperament and dimensional, latent psychopathology factors, including a general common psychopathology factor (p factor) and specific latent internalizing and externalizing liabilities, as captured by a bifactor model, in two independent samples of youth. Specifically, we tested the hypothesis that temperament factors of negative affectivity (NA), positive affectivity (PA), and effortful control (EC) could serve as both transdiagnostic and specific risks in relation to recent bifactor models of child psychopathology. Sample 1 included 571 youth (average age 13.6, SD = 2.37, range 9.3–17.5) …


Factors Affecting Mental Health Seeking Behaviors Of Law Enforcement Officers, Vincent M. Haecker Feb 2017

Factors Affecting Mental Health Seeking Behaviors Of Law Enforcement Officers, Vincent M. Haecker

Dissertations

The intent of this study was to elicit perspectives from law enforcement counselors, clinicians, chaplains, and peer group leaders for factors affecting law enforcement officer’s (LEOs) seeking mental health assistance. The law enforcement and mental health communities have gone to great lengths to ensure assistance is available to LEOs in an effort to counter the stress and trauma associated with the policing profession. Past studies attempted to elicit LEOs attitudes on mental health services, generating mixed results and were unable to establish why available services were underutilized. This study employed a qualitative methodology to elicit perspectives on this phenomena from …


Quantifying Cerebral Contributions To Pain Beyond Nociception, Choong-Wan Woo, Liane Schmidt, Anjali Krishnan, Marieke Jempa, Mathieu Roy, Martin A. Lindquist, Lauren Y. Atlas, Tor D. Wager Feb 2017

Quantifying Cerebral Contributions To Pain Beyond Nociception, Choong-Wan Woo, Liane Schmidt, Anjali Krishnan, Marieke Jempa, Mathieu Roy, Martin A. Lindquist, Lauren Y. Atlas, Tor D. Wager

Publications and Research

Cerebral processes contribute to pain beyond the level of nociceptive input and mediate psychological and behavioural influences. However, cerebral contributions beyond nociception are not yet well characterized, leading to a predominant focus on nociception when studying pain and developing interventions. Here we use functional magnetic resonance imaging combined with machine learning to develop a multivariate pattern signature—termed the stimulus intensity independent pain signature-1 (SIIPS1)—that predicts pain above and beyond nociceptive input in four training data sets (Studies 1–4, N¼137). The SIIPS1 includes patterns of activity in nucleus accumbens, lateral prefrontal and parahippocampal cortices, and other regions. In cross-validated analyses of …


Weight Loss Maintenance: Women's Experience During Perimenopause, Karren B. Liebert Feb 2017

Weight Loss Maintenance: Women's Experience During Perimenopause, Karren B. Liebert

Dissertations, Theses, and Capstone Projects

Women’s health may be at risk during middle age, a time when women in the United States often gain weight. Being overweight or obese during perimenopause increases a woman’s vulnerability to disabling health sequela in later life, such as cardiovascular disease, diabetes, depression and osteoarthritis, all of which increase morbidity, mortality, health care costs and decrease quality of life. Stigma and discrimination related to overweight and obesity are associated with delay and avoidance of health care, and with poorer quality health care. Weight loss often is followed by weight regain within three to five years. This qualitative study was designed …


Sociocultural Risk Factors For Elevated Perceived Stress Among African American Smokers, Monica Webb Hooper, Noella A. Dietz, Joseph C. Wilson Jan 2017

Sociocultural Risk Factors For Elevated Perceived Stress Among African American Smokers, Monica Webb Hooper, Noella A. Dietz, Joseph C. Wilson

Journal of Health Disparities Research and Practice

Introduction: African Americans experience unique stressors that may inhibit smoking cessation and enhance relapse rates. Few studies, however, have focused on risk factors for perceived stress among treatment seekers. Because African Americans are less likely to quit compared to the larger community, understanding factors associated with perceived stress among smokers has the potential to improve intervention outcomes. This study examined psychosocial and cultural correlates of stress in a sample of African American participants in a randomized controlled trial.

Methods: At baseline, participants reported demographic factors and completed assessments of smoking history, alcohol use, friend and household smoking, weight concerns, acculturation, …


The Effects Of Abilify On Memory, Coordination, And Stereotypy In Cd-1 Mice, Jostein Andersen Jan 2017

The Effects Of Abilify On Memory, Coordination, And Stereotypy In Cd-1 Mice, Jostein Andersen

Undergraduate Honors College Theses 2016-

The atypical antipsychotic Abilify is the second most popular treatment for schizophrenia and other related disorders. Its popularity and wide use is due to its unique pharmacological profile, working differently at dopamine and serotonin receptors compared to other antipsychotics. Schizophrenia is an infamous mental dysfunction involving cognitive impairment, positive symptoms, and negative symptoms. The current study investigated Abilify’s effect in a dose-dependent manner on memory, coordination and stereotypic movement. The sample consisted of 15 male and 15 female CD-1 mice. Memory was tested in a cognitive maze, the Rota-Rod series 8 model measured coordination, and the Coulbourn Tru-Scan Activity Box …

A System To Monitor Cognitive Workload In Naturalistic High-Motion Environments, Bethany K. Bracken, Seth Elkin-Frankston, Noa Palmon, Michael Farry, Blaise De B Frederick

H-Workload 2017: Models and Applications (Works in Progress)

Across many careers, individuals face alternating periods of high and low attention and cognitive workload can impair cognitive function and undermine job performance. We have designed and are developing an unobtrusive system to Monitor, Extract, and Decode Indicators of Cognitive Workload (MEDIC) in naturalistic, high-motion environments. MEDIC is designed to warn individuals, teammates, or supervisors when steps should be taken to augment cognitive readiness. We first designed and manufactured a forehead sensor device that includes a custom fNIRS sensor and a three-axis accelerometer designed to be mounted on the inside of a baseball cap or headband, or standard issue gear …


Towards A Not Obtrusive Low Cost Biosystem To Assess Risk Perception In Workplace Through Stress Detection, Emanuele Bellini, Serena Benevenuti, Chiara Batistini Jan 2017

Towards A Not Obtrusive Low Cost Biosystem To Assess Risk Perception In Workplace Through Stress Detection, Emanuele Bellini, Serena Benevenuti, Chiara Batistini

H-Workload 2017: Models and Applications (Works in Progress)

The main aim of the article is to build a method to assess risk perception in real time in order to early detect and prevent risk behaviors and possible human errors. To this end, the relation between mental workload and stress as critical factors affecting risk perception has been investigated. In particular the mental-physical activation generated by an increment of the workload has the effect of reducing the resources needed to perceive risk increasing the worker vulnerability. The complexity of the stress phenomenon suggested the adoption of an integrated view. The Functional Model has been adopted to for its holistic …

Rowan-Virtua School of Osteopathic Medicine Departmental Research

BACKGROUND: Huntington's disease (HD), is a neurodegenerative disorder that is associated with cognitive, behavioral, and motor impairments that diminish health related quality of life (HRQOL). The HD-PRO-TRIADTM is a quality of life measure that assesses health concerns specific to individuals with HD. Preliminary psychometric characterization was limited to a convenience sample of HD participants who completed measures at home so clinician-ratings were unavailable.

OBJECTIVES: The current study evaluates the reliability and validity of the HD-PRO-TRIADTM in a well-characterized sample of individuals with HD.

METHODS: Four-hundred and eighty-two individuals with HD (n = 192 prodromal, n = 193 early, and n …

Defining A Person: The Nurse At Risk For Compassion Fatigue, Ellen Johnston

Honors Undergraduate Theses

The intent of this thesis was to examine compassion fatigue in nurses through analysis of research studies conducted within the past five years in an effort to identify predisposing factors to the experience of compassion fatigue. Individual and institutional factors were identified as well as current strategies to assist with management of compassion fatigue. Findings indicated that being new to practice, having a trait negative affect, being younger in age, having a history of exposure to trauma and working in high emotionally stressful units predisposed individuals to the experience of compassion fatigue. Institutional factors included a lack of managerial support, …


The Physiological & Psychological Effects Of Sleep Deprivation, Nilson Aguilar Jan 2017

The Physiological & Psychological Effects Of Sleep Deprivation, Nilson Aguilar

Nebraska College Preparatory Academy: Senior Capstone Projects

Sleep deprivation is a serious issue that affects this nation as a whole and is sadly ignored, overlooked, and even dismissed. Through extensive research one could see that sleep deprivation causes several unwanted health issues: some of which include obesity, insomnia, and anxiety. From this research conducted over the physical and psychological effects of sleep deprivation one can conclude that with simple education over this serious topic the effects of sleep deprivation would in fact significantly decrease. This in turn would benefit several people, families, and even society as a whole.

From the research conducted one can see that as …


Buying Happiness: Property, Acquisition, And Subjective Well-Being, David Fagundes Jan 2017

Buying Happiness: Property, Acquisition, And Subjective Well-Being, David Fagundes

Faculty Articles

Acquiring property is a central part of the modern American vision of the good life. The assumption that accruing more land or chattels will make us better off is so central to the contemporary preoccupation with acquisition that it typically goes without saying. Yet an increasing body of evidence from psychologists and economists who study hedonics—the science of happiness—yields the surprising conclusion that getting and having property does not actually increase our subjective well-being. In fact, it might even decrease it. While scholars have integrated the insights of hedonics into other areas of law, no scholarship has yet done so …


Role Of Food Preoccupation And Current Dieting In The Associations Of Parental Feeding Practices To Emotional Eating In Young Adults: A Moderated Mediation Study, Natalie A. Williams, Dipti A. Dev, Maren Hankey, Kimberly A. Blitch Jan 2017

Role Of Food Preoccupation And Current Dieting In The Associations Of Parental Feeding Practices To Emotional Eating In Young Adults: A Moderated Mediation Study, Natalie A. Williams, Dipti A. Dev, Maren Hankey, Kimberly A. Blitch

Department of Child, Youth, and Family Studies: Faculty Publications

Parental feeding practices reflecting coercive control are related to children’s later eating behaviors, but the mechanisms underlying these effects remain poorly understood. This study examined the relationships between recalled childhood experiences of parental pressure to eat and restriction and current food preoccupation, dieting, and emotional eating in a racially diverse sample of college students (N = 711). Results revealed that parental restriction, but not pressure to eat, was associated with more emotional eating (r = 0.18, p < 0.0001). Food preoccupation mediated the association between restriction and emotional eating (95% CI [3.6495–7.2231]); however, a moderated mediation model revealed that the strength of the indirect effect of restrictive feeding on emotional eating through food preoccupation was significantly different for dieters and non-dieters (index of moderated mediation = 1.79, Boot SE = 0.79; 95% bias-corrected bootstrap CI [–3.5490 to –0.4515]). These findings provide unique insight into the mechanisms linking parental feeding practices with emotional eating in young adulthood. Future studies attempting to clarify the processes through which child feeding practices impact later eating behaviors should consider the role of current dieting.


Trial 1 Versus Trial 2 Of The Test Of Memory Malingering: Evaluating Accuracy Without A “Gold Standard”, Douglas Mossman, Dustin B. Wygant, Roger O. Gervais, Kathleen J. Hart Jan 2017

Trial 1 Versus Trial 2 Of The Test Of Memory Malingering: Evaluating Accuracy Without A “Gold Standard”, Douglas Mossman, Dustin B. Wygant, Roger O. Gervais, Kathleen J. Hart

EKU Faculty and Staff Scholarship

This study examines the accuracy of the Test of Memory Malingering (TOMM), a frequently administered measure for evaluating effort during neurocognitive testing. In the last few years, several authors have suggested that the initial recognition trial of the TOMM (Trial 1) might be a more useful index for detecting feigned or exaggerated impairment than Trial 2, which is the source for inference recommended by the original instruction manual (Tombaugh, 1996). We used latent class modeling (LCM) implemented in a Bayesian framework to evaluate archival Trial 1 and Trial 2 data collected from 1198 adults who had undergone outpatient forensic evaluations. …


Just World Beliefs, Identity Development, And Social Justice Advocacy Of Counselor Trainees, Sara Rundlett Jan 2017

Just World Beliefs, Identity Development, And Social Justice Advocacy Of Counselor Trainees, Sara Rundlett

All Master's Theses

This was the first study exploring the relationship between the belief in a just world, identity development, and social justice advocacy (SJA). A mixed methods design was conducted using a nationwide sample of ninety-seven counselor-in-training participants. Hypotheses included positive correlation between identity development and SJA, negative correlation between belief in a just world and SJA, and negative correlation between belief in a just world and identity development. Results were not significant but provided implications for future research and counselor training programs.


Non-Medical Use Of Prescription Drugs, Stress, Cultural Orientation, Utilization Of Healthcare, And Protective Factors Among College Students In China, Cheuk Chi Tam Jan 2017

Non-Medical Use Of Prescription Drugs, Stress, Cultural Orientation, Utilization Of Healthcare, And Protective Factors Among College Students In China, Cheuk Chi Tam

Theses and Dissertations

Background: Non-medical use of prescription drugs (NMUPD) refers to the use of prescription drugs which are traditionally utilized to manage pain or treat psychiatric problems but without a doctor’s prescription. In 2010, an investigation by the Substance Use and Mental Health Services Administration (SAMHSA) revealed that 5.3% of young adults (18 to 25-year-olds) in the United States reported past-month NMUPD. NMUPD has become a growing concern owing to associations with consequences such as college dropout, poor academic achievement, and health jeopardizing behaviors. College students' NMUPD has been well documented in the United States. Limited studies, however, have been conducted among …


Distress And Worry As Mediators In The Relationship Between Psychosocial Risks And Upper Body Musculosketal Complaints In Highly Automated Manufacturing, Fiona Wixted, Leonard O'Sullivan Jan 2017

Distress And Worry As Mediators In The Relationship Between Psychosocial Risks And Upper Body Musculosketal Complaints In Highly Automated Manufacturing, Fiona Wixted, Leonard O'Sullivan

H-Workload 2017: Models and Applications (Works in Progress)

As a result of an upward trend in automation, the requirement for supervisory monitoring and consequently, cognitive demand has increased in automated manufacturing. The incidence of musculoskeletal disorders has also increased in the manufacturing sector. A model was developed based on survey data to test if distress and worry mediate the relationship between psychosocial factors (job control, cognitive demand, social isolation and skill discretion), stress states and upper body musculoskeletal complaints in highly automated manufacturing companies (n=235). Cognitive demand was shown to be related to higher distress in employees. The data raise the question about the link between job control …


Petrochemical Plant Console Operator Workload:The Issues, David A. Strobhar Jan 2017

Petrochemical Plant Console Operator Workload:The Issues, David A. Strobhar

H-Workload 2017: Models and Applications (Works in Progress)

The console operators of certain petrochemical processes must maintain high levels of performance during process upsets or endanger personnel safety and the environment. Mismanagement of an upset can result in explosions, fires, and the release of hazardous chemicals to the environment. The change in workload from steady state to upset operation is significant, with alarms and control changes that are of an order of magnitude. This paper describes the state of console activity in process plants, particularly the increase with key upsets. Quantitative data on the nature of the console operator’s position, its workload during normal operation, and the requirements …


Towards A Continuous Assessment Of Cognitive Workload For Smartphone Multitasking Users, Angel Jimenez-Molina, Hernan Lira Jan 2017

Towards A Continuous Assessment Of Cognitive Workload For Smartphone Multitasking Users, Angel Jimenez-Molina, Hernan Lira

H-Workload 2017: Models and Applications (Works in Progress)

The intermeshing of Smartphone interactions and daily activities depletes the availability of cognitive resources. This excessive demand may lead to several undesirable cognitive states, which can be avoided by continuously assessing the user cognitive workload. Recently, many attempts have emerged to assess this workload by using psycho physiological signals. This paper provides evidence that it is possible to train models that accurately identify in short time windows such cognitive workload by processing heart rate and blood oxygen saturation signals. This assessment could be applied in Smartphone notification delivery, interface adaptations or cognitive capabilities evaluation.

A Workload-Centered Perspective On Reduced Crew Operations In Commercial Aviation, Daniela Schmid Jan 2017

A Workload-Centered Perspective On Reduced Crew Operations In Commercial Aviation, Daniela Schmid

H-Workload 2017: Models and Applications (Works in Progress)

Mental workload of a pilot, in short workload, depends on various characteristics of different accumulated tasks on the flight deck. Exogenous task demands and endogenous supply of attentional or information processing resources determine workload [1]. Performance is expect to drop if the demand exceeds the available resources of the pilot. Expertise and experience modulate the endogenous sup- ply of resources like perceiving, updating memory, planing, making a decision, and executing and processing a response. Subsequently, workload manifests in performance variables, subjective experience, and physiological parameters [2]. This is how we can summarize workload very brie y to introduce a model …


Moving Between Automated And Manual Driving: Mental Workload And Performance Implications, Totsapon Butmee, Terry C. Lansdown Jan 2017

Moving Between Automated And Manual Driving: Mental Workload And Performance Implications, Totsapon Butmee, Terry C. Lansdown

H-Workload 2017: Models and Applications (Works in Progress)

Automated driving has been predicted to take-over from manual vehicle control in the near future. The driver’s role may then change from active operator to passive observer. Such technology offers the tantalising promise of improving driving safety. However, many studies have presented findings suggesting potentially adverse effects from automated driving systems, e.g., reduced situation awareness. Mental workload is also a key issue of concern for researchers in this area. Excessive mental workload has repeatedly been shown to be associated with degraded driving performance. Previously, most traffic psychology studies on mental workload have focused the manual driving task. However, a shift …

Reducing Peak Workload In The Cockpit: A Human In The Loop Simulation Evaluating New Runway Selection Tool, Tanja Bos, Rolf Zon, Wilfred Rouwhorst

H-Workload 2017: Models and Applications (Works in Progress)

In efforts to increase safety and reduce peak workload situations in the cockpit, a tool with a different interaction style was developed for use in case of a runway change instructed by Air Traffic Control during approach. In an experiment a workload comparison was made between the new tool and the conventional cockpit. Workload was measured by means of a self-rating after each experiment run, as well as eye blink frequency during each run. Results show that the self-rated workload decreases with the new tool for one of the two crew members and the blink frequency suggests a workload decrease …
