The Effect Of Early Life Photoperiod Manipulation On Cocaine-Induced Behavioral Sensitization In Male And Female Japanese Quail, Shannon Elizabeth Eaton

Theses and Dissertations--Psychology

Estrogens seem to play a role in the locomotor activating effects of cocaine. Japanese quail provide a good model for hormonal manipulation as alterations of their photoperiod controls hormone levels. The current study aims to examine the role of early life photoperiod manipulation in cocaine-induced behavioral sensitization in quail. It was expected that if quail were raised on a short photoperiod, they would have a reduction in gonadal hormones and this reduction in hormones would affect the acquisition of cocaine-induced behavioral sensitization. Quail were raised on an 8L:16D or a 16L:8D light cycle. Following 2 days of habituation, quail were …

Cocaine Choice: A Novel Procedure For Investigating Neuronal Activation Mediating Cocaine Preference, Jonathan Jenn-Sheng Chow

Theses and Dissertations--Psychology

Cocaine use disorder is a significant health problem, negatively impacting individuals afflicted. While preclinical self-administration research has provided invaluable insight into the neurobehavioral mechanisms that underlie cocaine abuse, cocaine use outside of the laboratory occurs within an environment where other goods are also available ubiquitously. Although there is an ever-increasing literature investigating drug vs. non-drug choice in rodent models and how alternative goods can compete with the subjective value of cocaine, the neurobiological mechanisms that are associated with cocaine preference remains largely unknown. Additionally, current drug vs. non-drug choice studies use procedures that confound preference with intake, such that preference …

Development And Preliminary Validation Of A Five Factor Model Measure Of Machiavellianism, Katherine L. Collison, Colin E. Vize, Joshua D. Miller, Donald R. Lynam

Department of Psychological Sciences Faculty Publications

Machiavellianism is characterized by planfulness, the ability to delay gratification, and interpersonal antagonism (i.e., manipulativeness and callousness). Although its theoretically positive relations with facets of Conscientiousness should help distinguish Machiavellianism from psychopathy, current measurements of Machiavellianism are indistinguishable from those of psychopathy in large part because of their assessment of low Conscientiousness. The goal of the present study was to create a measure of Machiavellianism that is more in line with theory using an expert-derived profile based on the 30 facets of the five-factor model (FFM) and then test the validity of that measure by comparing it with relevant constructs. …

Antecedents And Consequences Of Burnout Among Professional Psychologists, Alisha Miller

Dissertations

Mental health professionals are thought to be uniquely at risk for burnout due to the personal nature of their work and the types of clients with whom they work. But, while the phenomenon of burnout has received attention in the general occupational health literature, research focused on the predictors and outcomes of burnout among professional psychologists remains relatively limited. This study focused on the antecedents and consequences of the emotional exhaustion and client depersonalization components of burnout and, guided by the job demands-resources model, had three main aims: a) examine job demands and job resources as predictors of emotional exhaustion …

Genetic And Environmental Influences Of Bullying Involvement: A Longitudinal Twin Study, Ellyn Dunbar

Theses and Dissertations

Introduction—Bullying involvement is associated with many long-term adverse outcomes. Bullied children are at risk for internalizing disorders including anxiety, depression and suicidal behavior in childhood and adulthood. Bullies are also at risk for psychiatric disorders, specifically externalizing disorders. Bully victims—children who are both bullied and bullies—have a particularly poor prognosis, with a higher risk for internalizing and externalizing disorders. The purpose of this study is to study the epidemiology, risk of psychiatric disorders, and genetic and environmental influences of being bullied, a bully, and a bully victim—in the sample and individually in males and females.

Methods—Twins (N=2,844, aged …

Aerobic Exercise Exposure Targeting Anxiety Sensitivity: Effects On Associated Health Behaviors In Young Adults, Autumn Lanoye

Theses and Dissertations

Anxiety sensitivity (AS) is associated with health behaviors such as low rates of physical activity, overeating, alcohol use, and poor sleep; however, interventions targeting AS via exercise-based interoceptive exposure have not assessed these as outcomes. In addition, previous studies are limited by brief follow-up periods. This study aimed to replicate previous aerobic exercise interoceptive exposures with an extended (6-week) follow-up and measurement of health behaviors.

Participants were 44 sedentary young adults with elevated AS randomized to intervention (6 20-minute sessions of moderate-intensity treadmill walking) or assessment-only control. Assessments took place at baseline, week 2 (post-treatment), week 4, and week 8 …

A Sensory-Based Program To Enhance Occupational Performance For Dementia, Naomi Grace Wong, Jacob Joseph Gantan, Ivy Annahi Torres-Flores, Heather Anne August

Student Research Posters

Dementia is a neurological disease, causing behavioral and cognitive symptoms, that progressively impairs an individual’s ability to engage in meaningful activities. Progressive deterioration associated with dementia impacts occupational performance and independence and quality of life. Sensory based interventions, such as drumming groups, have been hypothesized to be a non-pharmacological intervention for individuals with dementia. The purpose of this study was to analyze the effects of a sensory based intervention program, in this case participation in a drumming group, on functional engagement during self-feeding for individuals with dementia. Researchers gathered data over the course of two days using the Functional Behavior …

When Fatigue Symptoms Are Associated With . . . Fatigue Symptoms, Renzo Bianchi, Irvin Sam Schonfeld, Eric Laurent

Publications and Research

The study by Gül et al. (2017) is problematic in its conceptualization. We note that while "sluggish cognitive tempo” (SCT) remains an ill-defined entity, the same is true of burnout (e.g., there are no binding or consensual diagnostic criteria for either SCT or burnout). The concomitant use of such constructs is thus unlikely to promote clarity in research. Rather, it tends to escalate confusion.

On The “Bubble” Of Burnout's Prevalence Estimates, Eric Laurent, Irvin Sam Schonfeld, Renzo Bianchi, Laura Hawryluck, Peter G. Brindley

Publications and Research

Hawryluck and Brindley (2018) addressed the issue of burnout—a syndrome thought to be induced by job stress—among critical care medicine (CCM) practitioners. Although we agree that the practice of CCM can be stressful, relying on burnout as an indicator of the practitioners’ response to occupational adversity is unwarranted. Despite its popularity, burnout remains poorly defined. Disconcertingly, investigators have widely relied on the Maslach Burnout Inventory (MBI) for “diagnosing” burnout in spite of the fact that the MBI is not a diagnostic instrument.Experiencing fatigue or distancing oneself from one’ work—what burnout is about—is not necessarily a sign of ill-being in itself. …

Is A Meta-Analytic Approach To Burnout’S Prevalence Timely?, Eric Laurent, Irvin Sam Schonfeld, Renzo Bianchi

Publications and Research

Cañadas‐De la Fuente et al. performed a meta‐analysis of the prevalence of emotional exhaustion, depersonalization, and diminished personal accomplishment—the three definitional components of the burnout syndrome—among nursing professionals working in oncology units. All in all, their meta‐analysis was inconclusive because of the very state of burnout research. Because there is mounting evidence that burnout is a depressive condition, we recommend that investigators focus on depression, rather than burnout, in occupational health research and practice.

When We Say 'Physician Burnout,' We Really Mean Depression, Irvin Sam Schonfeld

Publications and Research

There has been controversy regarding the extent to which burnout overlaps depression. I enumerate eight reasons explaining to why depression is at the heart of burnout. Some of these reasons pertain to the highly similar work-related causes of burnout and depression, burnout adherents' faulty categorical and dimensional conceptualizations of burnout and depression, problematically high correlations between emotional exhaustion (the core of burnout) and depressive symptoms, research on physicians and dentists that underline burnout-depression overlap, and the problem of alexithymia being similarly related to burnout and depression. Suggestions for addressing the problem of burnout-depression among physicians are presented.

What Is The Difference Between Depression And Burnout? An Ongoing Debate, Irvin Sam Schonfeld, Renzo Bianchi, Stefano Palazzi

Publications and Research

Il burnout è concepito come una sindrome che si sviluppa in risposta a condizioni di lavoro cronicamente avverse. Si ritiene che il burnout comporti esaurimento emotivo, depersonalizzazione e riduzione della realizzazione personale. Storicamente, tuttavia, il burnout è stato difficile da separare dalla depressione. In effetti, i sintomi del burnout coincidono con i sintomi della depressione. L'evidenza della validità discriminante del burnout nei confronti della depressione è debole, sia a livello empirico sia a livello teorico. L'esaurimento emotivo, il nucleo del burnout, riflette una combinazione di umore depresso e affaticamento / perdita di energia e si correla molto bene con altri …

Burnout And Depressive Symptoms Are Not Primarily Linked To Perceived Organizational Problems, Renzo Bianchi, Eric Mayor, Irvin Sam Schonfeld, Eric Laurent

Publications and Research

In this 257-participant study (76% female; mean age: 44.84), we examined two ideas that are widespread among burnout researchers: (a) the idea that burnout is primarily related to occupational-level factors; and (b) the idea that burnout should be considered a sentinel indicator in research on negative occupational outcomes. We investigated the links between burnout and a series of generic and work-related variables, namely, depressive symptoms, neuroticism, extraversion, effort-reward imbalance in the job (ERI), social support at work (SSW), and turnover intention. Burnout was assessed with the Shirom-Melamed Burnout Measure, depressive symptoms with the PHQ-9, neuroticism and extraversion with the NEO-Five …

A Neglected Problem In Burnout Research, Renzo Bianchi, Irvin Sam Schonfeld, Eric Laurent

Publications and Research

Although we share with Eckleberry-Hunt et al. (2018) some of their criticisms regarding the problematic conceptualization of burnout, we are perplexed by the authors’ silence regarding burnout–depression overlap, which is arguably the most troubling problem attached to the burnout construct. The extensive research suggests that burnout reflects a combination of depressive responses. The emotional exhaustion component of burnout involves fatigue and depressed mood, two diagnostic criteria for depressive disorders. Maslach et al. (2001) wrote that there is “a predominance of dysphoric symptoms” in burnout. Depersonalization symptoms are commonly found in depressed individuals. Diminished personal accomplishment reflects well-known depressive manifestations of …

Inflammation As A Central Mechanism In Alzheimer's Disease, Jefferson W. Kinney, Shane M. Bemiller, Andrew S. Murtishaw, Amanda M. Leisgang, Arnold M. Salazar, Bruce T. Lamb

Psychology Faculty Research

Alzheimer's disease (AD) is a progressive neurodegenerative disorder that is characterized by cognitive decline and the presence of two core pathologies, amyloid β plaques and neurofibrillary tangles. Over the last decade, the presence of a sustained immune response in the brain has emerged as a third core pathology in AD. The sustained activation of the brain's resident macrophages (microglia) and other immune cells has been demonstrated to exacerbate both amyloid and tau pathology and may serve as a link in the pathogenesis of the disorder. In the following review, we provide an overview of inflammation in AD and a detailed …

Internal Medicine, East Africa

Aims:To assess the effectiveness of community-based alcohol brief interventions (ABI) implemented by community-health workers with and without motivational talks (MT) by former drinkers, in reducing harmful and hazardous alcohol consumption. Methods:We conducted a three-arm quasi-experimental study (one control and two intervention groups) between May and December 2015 in Kakamega County, Kenya. Participants were hazardous or harmful alcohol drinkers with an Alcohol Use Disorders Identification Test (AUDIT) score of 8–19 at baseline. One intervention group received only ABI while the other received ABI + MT. The interventions’ effects on AUDIT scores were analysed using linear mixed models. Logistic regression …

Analysis Of Ptprk Polymorphisms In Association With Risk And Age At Onset Of Alzheimer’S Disease, Cancer Risk, And Cholesterol, Yang Chen, Chun Xu, Sam Harirforoosh, Xingguang Luo, Ke-Sheng Wang

Health & Biomedical Sciences Faculty Publications

The human receptor-type protein-tyrosine phosphatase kappa (PTPRK) gene is highly expressed in human brain and is previously associated with neuropsychiatric disorders and cancer. This study investigated the association of 52 single nucleotide polymorphisms (SNPs) in the PTPRK with the risk and age at onset (AAO) of Alzheimer’s disease (AD) in 791 AD patients and 782 controls. Five SNPs (top SNP rs4895829 with p=0.0125) were associated with the risk of AD based on a multiple logistic regression (p

Personality Oriented Job Analysis To Identify Non-Cognitive Factors For A Doctor Of Physical Therapy Program In The United States, Maureen A. Conard, Kristin Schweizer

Psychology Faculty Publications

It aimed to conduct a personality oriented job analysis to identify non-cognitive factors that may predict successful performance or performance difficulties in doctorate in physical therapy (DPT) students. The study employed focus groups and a survey with 9 DPT subject matter experts. Focus group participants including 3 DPT faculty members and 4 recent graduates of the DPT program identified 22 non-cognitive factors. Out of them, 15 factors were possibly associated with successful performance and 7 factors were possibly associated with performance difficulties. The questionnaire employing the Combination Job Analysis Method resulted in 12 factors which could be used in selection, …
