Memory Complaint Profiles In Dementia Populations Utilizing The Memory Complaints Inventory, Becca N. Johnson

Graduate Theses/Dissertations

The Memory Complaints Inventory (MCI) is a self-report questionnaire developed by Paul Green to provide further effort-related evidence in neuropsychiatric practice. It is comprised of nine subscale scores, in addition to the imbedded Plausible and Implausible symptom validity scales. The current study utilized archival MCI scores in dementia populations to determine the presence of, and difference between, genuine memory impairment profiles in separate subgroups of cognitive impairment. The study sample consisted of 244 adults presenting to an outpatient neuropsychology practice for evaluation of memory impairment. The diagnostic categories of the sample consisted of Alzheimer’s Disease (n = 21), Vascular …

Detecting Suicide Risk From Wristworn Activity Tracker Data Using Machine Learning Approaches, Pallavi Atluri

Electrical Engineering Theses

Suicide is a prevalent cause of death worldwide and depression is a primary concern of many suicidal acts. It is possible that an individual during depression never has any suicidal thoughts at all. On the other hand, some individuals in stable condition with no apparent symptoms of depression feel urges to commit suicide (suicidal ideation). Many such individuals never let anyone know what they are feeling or planning. Suicidal ideation considered an important precursor to suicidal acts.

Detecting the suicide risk in individuals with mood disorders is a major challenge. The current clinical practice to assess suicide risk in these …

Neural Hypervigilance In Trauma-Exposed Women, Seungyeon A. Yoon

Dissertations, Theses, and Capstone Projects

Trauma-exposed people often experience hypervigilance, which is a tonic condition of elevated alertness and excessive scanning for potential threat. A cardinal feature of hypervigilance is that no actual threat is needed to evoke or maintain the over-alertness and heightened affective response. However, most neuroimaging research in trauma to date has only focused on reactivity to an actual threat. Thus, the overarching aim of this dissertation was to investigate neural signatures and salivary markers of post-trauma hypervigilance in the absence of threat that can cause impairment in daily functioning and contribute to developing other trauma-related symptoms such as heightened threat reactivity. …

Burnout Syndrome And Depression, Renzo Bianchi, Irvin Sam Schonfeld, Eric Laurent

Publications and Research

In this chapter, we proposed an overview of burnout, from the introduction of the construct in the mid-1970s to the growing realization that the syndrome was better conceived of as a depressive condition. Recent studies have shown that the distinction between burnout and depression is problematic, both theoretically and empirically. The history of burnout research suggests that transdisciplinary communication and methodological standards should be strengthened to avoid the proliferation of constructs that, in fact, refer to the same phenomena. Construct proliferation, a transgression of the scientific canon of parsimony, is considered a major problem today because it undermines theory building …

Effects Of Nicotine Exposure On Methamphetamine Oral Self-Administration, Extinction, And Reinstatement In Adolescent Rats, Zachary Robert Harmony

Electronic Theses, Projects, and Dissertations

Adolescence is a vulnerable developmental period in regards to drug initiation and use. The gateway hypothesis suggests that adolescent cigarette smoking may result in a heightened risk for methamphetamine use. However, little is understood about the role of nicotine on adolescent methamphetamine addiction. The aim of the present study was to determine whether early, late, or continuous adolescent nicotine exposure would alter oral methamphetamine self-administration, extinction, or reinstatement. A total of 164 male and female Sprague-Dawley rats were pretreated with saline or nicotine (0.16, or 0.64 mg/kg, sc) beginning on postnatal day (PD) 25 for 10 consecutive days. On PD …

Activation And Habituation Of The Cingulate Cortex During Emotion Processing In Healthy Controls, Borderline, And Schizotypal Personality Disorder, Emily Balevich

Dissertations, Theses, and Capstone Projects

Disturbances in emotional functioning are central features of the clinical profiles of both borderline and schizotypal personality disorder (BPD and SPD, respectively). BPD is characterized by a high sensitivity to emotional stimuli and unusually strong and long-lasting reactions, indicative of impaired habituation to emotional stimuli (Linehan, 1993). Previous research suggests that SPD patients demonstrate limbic hyper-reactivity to unpleasant stimuli, at least initially, but intact habituation to repeated presentation of unpleasant stimuli (Hazlett et al., 2012). The cingulate cortex supports various aspects of emotion processing and regulation, and abnormalities of this region have been related to emotion dysfunction in SPD and …

Cumulative Trauma, Emotion Reactivity And Salivary Cytokine Response Following Acute Stress Among Healthy Women., Yvette Z. Szabo

Electronic Theses and Dissertations

This study furthers understanding of how trauma exposure may be connected to the development and maintenance of poor health by focusing on cytokines, tightly regulated proteins of the immune system. Cytokine responses to acute stress have been associated with the onset of poorer mental health in physically healthy women. The present study examined how two factors recently associated with cytokine reactivity –cumulative trauma and emotion reactivity– are associated with salivary cytokine reactivity among healthy women. Seventy-one women, screened to be physically and mentally healthy, completed a laboratory acute stress paradigm and self-report measures of state emotion and trauma exposure. Participants …

Cognitive Functioning During Conflict In Intimate Partner Relationships Between Traumatized And Non-Traumatized Samples, Kylie N. Coleman

Doctor of Psychology (PsyD)

Significant differences have been found in neural connectivity of the brain in frontal, central, temporal, and parietal areas of individuals who experienced childhood trauma compared to those who had not (Cook, Ciorciari, Varker, & Devilly, 2009). This study investigated the relationship between the number of distressing and traumatic life experiences and participants’ neural responses to observing simulated conflict in intimate relationship. Graduate students (n = 11) answered conflict resolution and emotional activation questions while watching a simulated, escalating marital conflict. The participants’ neural responses were recorded via EEG mean power data from frontal and temporal brain regions. Heart rate (bpm) …

Neuroendocrine And Psychological Factors Associated With Burnout, Compassion Fatigue, And Reduced Compassion Satisfaction In Mental Health Professionals, Michelle Huffman

UNO Student Research and Creative Activity Fair

Mental health professionals are at increased risk for burnout, compassion fatigue, and reduced compassion satisfaction. Burnout is characterized by emotional exhaustion, depersonalization, and loss of personal accomplishment. Compassion fatigue is a more progressed disruption relative to burnout marked by insomnia/nightmares, arousal, loss of objectivity, isolation, and intrusive thoughts. Compassion satisfaction buffers against burnout and compassion fatigue. Although links between demographic, psychological, and biological factors have been documented, interactions between these factors have not been explored. Mental health professionals completed psychological inventories measuring depression, anxiety, burnout, compassion fatigue, and compassion satisfaction. Saliva samples were collected during the Trier Social Stress Test …

Restoration Of Attentional Deficits After Concussion, Katharine B. Earle

Cal Poly Humboldt theses and projects

Difficulties with concentration and attention are among the most prevalent symptoms experienced after concussion. Rest has been the most common form of recovery from concussion; however, new research is suggesting mild mental exertion to be an effective aid in recovery. Drawing from Attention Restoration Theory, this study evaluated the idea that cognitive engagement with natural environments can mitigate post-concussion directed-attention deficits. A between subjects repeated measures design was used to test directed-attention after video exposure to restorative/nature and nonrestorative/city environments. Measures of mood, connectedness to environment, and symptomology scores were also collected. No meaningful difference between exposure type was found …

The Impact Of Stress On Steroid Hormones And Cue Reactivity In Smokers And Gamblers, Stephanie Elaine Wemm

Legacy Theses & Dissertations (2009 - 2024)

Addictions, both substance and behavioral, have been conceptualized as having similar biopsychosocial processes with different opportunistic expressions (Shaffer et al., 2004). Biological processes such as the hormonal response to stress as measured by cortisol, dehydroepiandrosterone (DHEA), and the ratio of the DHEA/cortisol may be among the variables underlying the disposition to develop an addictive disorder, regardless of whether it is a substance-based or a so-called behavioral addiction. The current study aimed to examine whether physiological and psychological reactions to stress are similar in high-frequency smokers and gamblers. The subjective (urges, cravings) and physiological responses (skin conductance and heart rate) of …

Differentiating The Effects Of Animal-Assisted Versus Equine Facilitated Psychotherapy On Positive Psychological Outcomes Through A Stress Induction Context, Catherine J.V. Jones

College of Graduate Studies: Theses & Dissertations

The unique benefits of Equine Facilitated Psychotherapy (EFP) such as the human-horse bond, a non-traditional therapy setting, and performing altruistic acts are thought to facilitate positive change in humans. One mechanism by which positive changes occur is through improved coping and resilience in the face of stress. To date, only a handful of correlational studies speak to the potential effects of EFP on resilience-based outcomes. Thus, this study sought to address this gap in the literature by exploring the benefits of EFP compared to traditional Animal Assisted Therapy (AAT) in an experimental context. Specifically, we examined the effects of different …

Observational Assessment Of Empathy In Parent-Child Verbal Exchanges And Their Influence On Child Behavior, Patty Carambot

Dissertations, Theses, and Capstone Projects

Empathy, the ability to both experientially share in and understand others’ thoughts, behaviors, and feelings, is vital for human adaptation. Deficits in empathy development have implications across the lifespan for the development of prosocial behavior, social functioning, mental health disorders, and risk for antisocial behavior (e.g., Guajardo, Snyder, & Petersen, 2009; Moreno, Klute & Robinson, 2008). In light of these societal and individual burdens, it is imperative to foster and strengthen the development of this ability early in life to prevent or ameliorate such negative outcomes. This type of prevention can take a variety of forms, but parent and child …

Ptsd From Childhood Trauma As A Precursor To Attachment Issues, Christy Owen

Fidei et Veritatis: The Liberty University Journal of Graduate Research

The past 20 years have been turbulent regarding Reactive Attachment Disorder (RAD), with conflicting research about its causes, effects, treatment, and prognosis. The current diagnostic criteria in the DSM-5 fails to adequately address this disorder. A number of deviant and maladaptive behaviors common amongst children with RAD are not even mentioned in the diagnostic criteria. As such, the diagnostic definition is almost unidentifiable or incompatible with real-life conduct manifestations of the disorder. Rather, this author contends that RAD is foundationally a unique and extreme form of Posttraumatic Stress Disorder (PTSD) from Early Childhood Trauma. The child endured unspeakable neglect and/or …

Nicotine And Methylphenidate Chornic Exposure On Adult Cannabinoid Receptor Agonist (Cp 55,940) Place Conditioning In Male Rats, Christopher P. Plant

Electronic Theses, Projects, and Dissertations

A problematic connection has been reported between those who use nicotine related products alone or in combination with ADHD medications, like methylphenidate (MPH), in late childhood or early adolescence and the increased likelihood of later marijuana abuse in adulthood. Pre-clinical studies have found that the use of nicotine during the early adolescence period produces enduring changes to the endocannabinoid system in the brain. Since CB agonists, like marijuana, exert their effect through the eCB system, it is possible that early nicotine use may alter the rewarding nature of CB agonists in adulthood. In addition, MPH has also been shown to …

Previous Exposure To Lsd Fails To Enhance The Psychomotor Stimulant Effects Of D-Amphetamine In Male Sprague-Dawley Rats, Keli Herr

Research and Creative Activities Poster Day

• The hallucinogenic effects of lysergic acid diethylamide (LSD) have been largely attributed to its high affinity for 5-HT2A receptors. However, LSD also has a high affinity at several other monoamine receptors (Nichols, 2004; Passie et al., 2008).
• The contribution of dopaminergic mechanisms to LSD’s behavioral effects have not been investigated to the same extent that serotonergic mechanism have been studied. Some authors have hypothesized that chronic treatment of rats with LSD may produce a persistent behavioral state characterized by sensitivity to dopamine agonists (Marona-Lewicka and Nichols, 2007).
• Repeated exposure to psychostimulant drugs is known to produce progressive increases in locomotor …

Understanding Mental Toughness And Stress: The Role Of Cortisol, Alexis K. Satterwhite Ms.

Honors Program Theses

Mental toughness research aims to understand how two people of the same skill level, experience, and background react to pressure and stress, with one succumbing to the pressure while another succeeds (Clough & Strycharczyk, 2012). This study used Clough, Earle, and Sewell’s (2002) four C’s of mental toughness (commitment, challenge, control, and confidence) as a theoretical framework. The current study aims to explore physiological aspects of mental toughness through cortisol, a stress hormone that is released as an internal reaction to some type of threat occurring externally to the body (Kottler & Chen, 2011). The relationships between mental toughness and …

Relation Between Harsh Parenting Exposure In Childhood And Adult Externalizing Symptoms : Moderating Role Of The Autonomic Nervous System, Samantha Aldea Barry

Legacy Theses & Dissertations (2009 - 2024)

Though literature suggests that many individuals with childhood attention-deficit/hyperactivity disorder (ADHD) and oppositional defiant disorder (ODD) report having symptoms of the respective disorder as adults, little is known about potential predictors of adulthood externalizing symptoms. The proposed study examines the impact of the parasympathetic nervous system (PNS), as measured by respiratory sinus arrhythmia (RSA), and the sympathetic nervous system (SNS), as measured by skin conductance levels (SCL), on the link between harsh parenting experienced during childhood and ADHD and ODD symptoms during young adulthood. Results yielded a significant two-way interaction between harsh parenting and resting RSA, which significantly accounted for …

Effect Of Prior Trauma Exposure On Alpha Amplitude, Heart Rate, And Self-Reported Negative Affect, Gina L. Denoble

All Master's Theses

This study was conducted to investigate whether the number of traumatic events an individual has previously experienced influences that individual’s physiological and psychological reactions when exposed to a negative affective stimulus followed by a mindfulness-based stress reduction (MBSR) intervention. Twenty-eight participants were placed into intact quasi-experimental groups based on their scores on the Traumatic Life Events Questionnaire (TLEQ). The negative affective stimulus consisted of a series of photos bearing negative affective valence. The photos were selected from the International Affective Picture System (IAPS), and paralleled the areas of trauma exposure evaluated by the TLEQ. All participants were exposed to the …

Slam Poetry: An Online Intervention For Treating Depression, Spencer J. Ruchti, Mercedes Becker, Cara Mckee, Austin Herron, Alex Swalling

Undergraduate Theses, Professional Papers, and Capstone Artifacts

Given that depression is the “leading cause of disability worldwide,” and that less than 50% of people suffering from depression receive treatment, this study aims to provide support for a globally accessible depression treatment (WHO, 2012). The study conducted implemented an internet-based treatment for depression in which users were provided an opportunity to watch slam poetry videos related to mental health issues and write free responses regarding the content of the videos and their subjective experience of depression. Numerous studies provide support for the effectiveness of expressive writing, online mental health interventions, and slam poetry in particular for reducing symptoms …

Initiation And Retention In Couples Outpatient Treatment For Parents With Drug And Alcohol Use Disorders, Abbly L. Braitman, Michelle L. Kelley

Psychology Faculty Publications

The focus of the current study was to identity mental health, relationship factors, substance use related problems, and individual factors as predictors of couples-based substance abuse treatment initiation and attendance. Heterosexual couples with children that met study criteria were invited to attend 12 sessions of outpatient behavioral couples therapy. Men were more likely to initiate treatment if they had a higher income, had greater relationship satisfaction, were initiating treatment for alcohol use disorder only, were younger when they first suspected a problem, and had higher depression but lower hostility or phobic anxiety. Men attended more treatment sessions if they reported …

The Effects Of Pet Ownership On Anxiety And Depression Among Trauma-Exposed College Students, Dung N. Nguyentran, Marlene A. Michniak, James J. Jung, Christine Q. Do

Undergraduate Research Posters

Rates of anxiety and depression are prevalent in college students and can be attributed in part to stress and trauma-related events. However, studies suggest that pet ownership has the possibility of alleviating symptoms of anxiety, depression, negative emotions, and suicide. The purpose of this study was to determine the relationship between pet ownership and levels of anxiety and depression among those who have experienced a traumatic event. The sample was comprised of five hundred and forty-seven VCU students who completed an online survey from Spit for Science during their junior year. Linear regressions were performed to determine the nature and …

Are Women Higher In Anxiety Than Men? United States Surveys, 2003‐2013, Rabale Hasan

Honors Scholar Theses

A large proportion of the U.S. population suffers from anxiety and related mental illnesses. An in-depth analysis needs to examine all possible factors that may explain why anxiety is on an upward trend and why women are more likely than men to present with anxiety. This study examined the anxiety in five cross-sectional United States surveys (Total N=19,630) taken in 2003, 2006, 2009, 2011, and 2013. Predictors such as demographics (e.g., race, age, gender), medical conditions, behavioral choices (e.g., BMI, exercise, sleep), and psychosocial stressors were investigated. Linear regression and logistic regression analyses were used to examine trends. Anxiety is …

Interactions With Horses Is Associated With Higher Mindfulness And Heart Rate Variability And Lower Electrodermal Response In College Students, Sarah Mary Wach

USC Aiken Psychology Theses

A wealth of research has revealed psychological and physiological benefits of interactions with animals. As yet, research is limited to smaller animals such as dogs and cats and has not examined the benefits of human-horse interactions. The present study examined the effects of video-simulated human-horse interactions compared with simulated interactions with a car and a person on state mindfulness and physiological arousal. The relationship between trait mindfulness and horse experience was also examined. Undergraduate students with (n = 16) and without experience with horses (n = 26) were recruited with the exclusion criteria of a fear of horses. …

A Pilot Study On The Effects Of Exercise On Depression Symptoms Using Levels Of Neurotransmitters And Eeg As Markers, Timothy H. Barclay, Scott Richards, James Schoffstall, Chad Magnuson, Christine Mcphee, Josh Price, Stephen Aita, Audrey Anderson, Dan Johnson, Jerry Price

Faculty Publications and Presentations

Context: The prescribing of exercise by physicians has become a popular practice, yet the effectiveness of exercise on symptoms of depression is difficult to determine due to a lack of randomized controlled trials with clinical populations. Reports also indicate that only a small percentage of physicians advise their patients regarding exercise and confusion still exists as to how much and what types are best. Aims: To understand the mechanisms that make exercise a viable treatment in depression. Settings and Design: This study employed a six‑week, two group, single‑level trial, pre‑ and posttest design using self‑report of symptoms, blood …

Stress, Anxiety, And Somatic Symptoms: A Comparison Of Biomarkers In A Clinical Sample, David J. Finitsis

Master's Theses

Anxiety disorders are the most prevalent class of mental disorders, often characterized by a chronic course and comorbid psychopathology. The anxiety-stress literature utilizing cortisol as a biomarker of the hypothalamus pituitary adrenal (HPA) axis has been inconsistent. The establishment of salivary alpha-amylase (sAA) as a biomarker of sympathetic nervous system (SNS) activation allows researchers an opportunity to examine the stress response more fully. This study sought to explore relationships between trait anxiety and salivary stress biomarkers in an outpatient sample attending a specialized anxiety treatment center. Multiple regression and moderator analyses were conducted to examine associations between psychosocial and physiological …

Expression Of Borderline Personality Disorder Symptoms Across The Ovulatory Cycle: A Multilevel Investigation, Tory A. Eisenlohr-Moul

Theses and Dissertations--Psychology

Borderline Personality Disorder (BPD) is a disabling condition characterized by chronic emotion dysregulation and behavioral impulsivity. Prospective studies that test proposed mechanisms of within-person change in BPD hold the key to improving symptom predictability and control in this disorder. A small body of evidence suggests that fluctuations in estradiol such as those occurring naturally at ovulation during the monthly female reproductive cycle may increase symptoms in women with BPD (DeSoto et al., 2003). Furthermore, there is preliminary evidence that both self-esteem and feelings of social rejection are highest at ovulation, when estradiol peaks (Durante and Hill, 2009; Eisenlohr-Moul et al., …

The Relationship Between Suicide Ideation And Parasuicide: An Electrophysiological Investigation Using The Loudness Dependence Of Auditory Evoked Potential, Angelika Marsic

Dissertations

The loudness dependence of the auditory evoked potential (LDAEP) has been proposed as a promising valid and a non-invasive indicator of behaviorally relevant central 5-HT functioning. There is limited research on the utility of the LDAEP in discriminating individuals who engage in various degrees of suicidal behavior. The primary purpose of the present study was to examine if the LDAEP, as a measure of central serotonergic functioning, can be useful in distinguishing groups of individuals who: (a) solely experience suicidal ideation (SI group); (b) experience suicidal ideation and have engaged in deliberate self-harm acts (SH group); and (c) individuals with …

The Effects Of An Online Sleep Hygiene Intervention On Students' Sleep Quality, Giuliana Farias

Psychology Theses & Dissertations

Students in college or in their first year of medical school undergo increased educational and social pressure. To cope, students may sacrifice sleep to meet demands. Poor sleep affects learning, performance, and health. Studies have been successful at improving sleep quality through the use of in-person recruitment or cognitive-behavioral therapy delivered over the internet (Trockel, Manber, Chang, Thurston, & Tailor, 2011). The purpose of the current study was to investigate whether an online sleep hygiene intervention could improve sleep quality. One hundred thirty-eight students from one undergraduate institution in Southeast Virginia completed this study. Students were divided into groups; one …

The Association Of Cognitive Function With Autonomic-Cardiovascular Reactivity To And Recovery From Stress, Sanjay Mehta

Psychology Theses & Dissertations

The contribution of stress in the development of chronic and terminal disease has garnered significant interest in contemporary research. The current study aims to look at how performance in domains of cognitive function may affect autonomic-cardiovascular reactivity and recovery to psychologically stressful tasks as such reactions, over time, may contribute to the development of cardiovascular disease.

The current study analyzed data from 209 healthy middle-age adults. This included four neuropsychological tests utilized here to represent abilities in four different cognitive domains: response inhibition, mental flexibility, verbal memory, and nonverbal memory. The participants were also introduced to three psychologically stressful tasks …
