Therapeutic Horseback Riding With Military Veterans: Perspectives Of Riders, Instructors, And Volunteers, Leslie Lafleur

Antioch University Dissertations & Theses

Statistics reveal that over 353,000 military members have been diagnosed with PTSD and/or TBI resulting from war-related activities. With the rising number of war stress injuries, there have not been enough psychotherapeutic services to meet the current demand for the care of returning veterans from Iraq and Afghanistan. Although some intervention strategies have been deemed successful, the current standards of care (e.g., exposure therapy, cognitive therapy) are limited by training inadequacies, accessibility, and outcomes (e.g., retention, early drop out, resistance, non-responsiveness). Furthermore, it is unclear whether these treatments are efficacious in addressing the unique symptom presentations of this population. The …

The Effect Of Emotion On Associative And Item Memory, Priyanga Jeyarathnarajah

Theses and Dissertations (Comprehensive)

Numerous studies to date have demonstrated superior memory for emotional compared to neutral stimuli (Kensinger & Corkin, 2004; Bennion et al., 2013). This finding, although relatively stable across the item memory literature, becomes less consistent when examined in tasks measuring memory for associative or source information (Chiu et al., 2013). For this reason, the present study set out to examine how emotional content (negative, positive and neutral word pairs) influences memory in two distinct associative and item recognition tasks: associative identification (AI), associative reinstatement (AR), paired-item recognition, and single-item recognition. In measuring the influence of emotion on associations using an …

The Role Of Heart Rate Variability In The Treatment Of Migraines, Thomas M. Ledoux

Antioch University Dissertations & Theses

This dissertation assessed the role of heart rate variability (HRV) in the treatment of migraine headaches. The extent of this relationship was measured through a 12-session HRV biofeedback protocol to increase HRV and decrease migraine frequency through resonance frequency breathing (RFB) training. This project used a single-case design methodology to analyze phase changes in physiological variables with a specific focus on changes in HRV and migraine symptoms from baseline to completion of the biofeedback protocol. The prevalence of migraine headaches is discussed, the history of biofeedback as an intervention for migraine is reviewed, and the rationale for the relationship between …

Behavioral Adjustment In Children With Life Threatening Illness A Qualitative Study, E. Joseph Becher Jr.

Antioch University Dissertations & Theses

This study investigated factors that affect adjustment in children with life-threatening illness from the viewpoint of the parents/caregivers. The data were collected from parents/caregivers whose children have a life threatening diagnosis. Parents/caregivers were interviewed and asked to complete the Parent Request Questionnaire (PRQ) which was given to them after the in-person interview. This newly developed PRQ was utilized into prior research to predict the levels of adjustment in children. It includes age, whether the child has been informed of the diagnosis, whether the child engages in age-appropriate activities, the child's prior experience with death, the child's family's involvement in treatment, …

My Heart Is In The East: Exploring Theater As A Vehicle For Change, Inspired By The Poetic Performances Of Ancient Andalucía, Jessica Litwak

Antioch University Dissertations & Theses

This study addresses the research question “How Do I Inspire Personal and Social Change Through My Theater Practice?” I implement the theory and practice of H.E.A.T., a fusion theater system, combining use of theater arts as healing practice, educational asset, activist tool, and an art form.I research different ways that theater can affect change, focusing specifically on the use of history in performance.I dramatically interpret a period of history where performance and poetry contributed to change.I utilize qualitative methods including performance ethnography, auto ethnography, arts-based research, and historical research.I describe the fieldwork in conflict zones in the Middle East, which …

Using A Delayed Match-To-Samples Task To Investigate The Isolated Processing Of Geometric Shapes And Their Corresponding Shape Words, Joshua E. Edwards

College of Graduate Studies: Theses & Dissertations

Evidence suggests an isolated system dedicated to processing geometric information (Spelke, Lee, & Izard, 2010), but isolating geometric processing from semantic processing has remained difficult. Recently, Sturz, Edwards, and Boyer (2014) utilized a delayed match-to-sample (DMTS) task to present participants with a sample composed of a shape, shape word, or a bi-dimensional stimulus composed of a shape and a shape word. After a delay, participants were required to identify the sample shape or the sample word by selecting between two shapes or two shape words. Results suggested that sample shapes did not interfere with selecting a correct match in the …

Decreased Sound Tolerance (Dst): Prevalence, Clinical Correlates, And Development Of A Dst Assessment Instrument, Therese Verkerke Cash

Theses and Dissertations

Decreased sound tolerance (DST) conditions, including misophonia and hyperacusis, are emerging clinical conditions in behavioral medicine. Misophonia involves an extreme emotional response (often anger, disgust, or annoyance) to specific sounds (such as people chewing, swallowing, tapping their foot on the floor, etc.), while hyperacusis is defined by high sensitivity to sounds below normal sound sensitivity thresholds. Although research on these DST conditions is increasing, clearly defined prevalence rates, associations with other mental health conditions, and development of assessment tools that can identify and differentiate DST symptoms are needed. Research and clinical reports also suggest that DST problems are more likely …

Evaluating And Increasing The Range Of Reinforcers For Individuals With Autism Spectrum Disorder, Megan Kliebert Wiggins

LSU Doctoral Dissertations

Prior research has demonstrated the utility of several preference-assessment methodologies to identify stimuli more likely to function as reinforcers for individuals with limited verbal repertoires. However, differing results have been obtained from studies evaluating the reinforcement effects of stimuli identified as high preference by one assessment method but low preference by another assessment method. The first focus of the project was to evaluate the reinforcing efficacy of edible and leisure items based on predictions from preference assessments. Results indicated that edible and leisure items approached frequently during a single-stimulus preference assessment but infrequently during a paired-stimulus preference assessment produced less …

The Feasibility Of Implementing A Novel Electrical Stimulation Device In The Self-Management Of Hand Burn Pain, Katrina Liddiard

Theses : Honours

Burns are widely acknowledged as one of the most painful injuries experienced, and poorly controlled pain following burn injury has been linked to reduced psychological adjustment, lower quality of life, and increased risk of developing a chronic pain state. Transcutaneous electrical nerve stimulation has been used for pain relief in a range of medical conditions, and may have the potential to reduce pain and analgesic consumption for burns patients. The burn care environment presents unique challenges to the introduction of new interventions, and the feasibility of introducing a novel form of electrical stimulation into this environment has not been tested. …

Gabapentin Alleviates Affective Pain After Traumatic Nerve Injury, Ryan B. Griggs, Michael T. Bardo, Bradley K. Taylor

Psychology Faculty Publications

Gabapentin reduces behavioral signs of stimulus-evoked allodynia and hyperalgesia in preclinical studies of traumatic nerve injury, but its effects on more clinically relevant measures of stimulus-independent pain are unclear. To address this gap, we determined whether gabapentin would relieve affective pain after spared nerve injury (SNI). Twelve days after sham or SNI surgery, we administered gabapentin over three consecutive conditioning days and then evaluated conditioned place preference. Gabapentin produced conditioned place preference and reversed mechanical hypersensitivity in SNI but not sham rats at a dose (100 mg/kg) that did not change open-field activity. These results show for the first time …

Role Of Ionotropic Glutamate Receptors In Delay And Probability Discounting In The Rat, Justin R. Yates, Seth R. Batten, Michael T. Bardo, Joshua S. Beckmann

Psychology Faculty Publications

Rationale Discounting of delayed and probabilistic reinforcement is linked to increased drug use and pathological gambling. Understanding the neurobiology of discounting is important for designing treatments for these disorders. Glutamate is considered to be involved in addiction-like behaviors; however, the role of ionotropic glutamate receptors (iGluRs) in discounting remains unclear.

Objectives The current study examined the effects of N-methyl-D-aspartate (NMDA) and α-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid (AMPA) glutamate receptor blockade on performance in delay and probability discounting tasks.

Methods Following training in either delay or probability discounting, rats (n=12, each task) received pretreatments of the NMDA receptor antagonists MK-801 (0, 0.01, 0.03, 0.1, …

The Use Of Psychological Defense Mechanisms – By Librarians And The Public – In Response To Traditional And Binary Librarian Stereotypes, Beth Posner

Publications and Research

Images of librarians in popular culture include the traditional stereotype - of a mousy spinster who cares more for protecting books than for helping people - as well as several contrasting or binary images - such as librarians who are wild by night (although quiet by day), know-it-alls (rather than know-nothings), or high-tech (instead of old-fashioned.) In response to the anxiety provoked by the more pernicious aspects of these images, both librarians and the public may employ a variety of common unconscious defense mechanisms. This chapter examines some of those used by the public - including stereotyping, and splitting or …

Central And Peripheral Contributions To Dynamic Changes In Nucleus Accumbens Glucose Induced By Intravenous Cocaine, Ken Wakabayashi, Eugene A. Kiyatkin

Department of Psychology: Faculty Publications

The pattern of neural, physiological and behavioral effects induced by cocaine is consistent with metabolic neural activation, yet direct attempts to evaluate central metabolic effects of this drug have produced controversial results. Here, we used enzyme-based glucose sensors coupled with high-speed amperometry in freely moving rats to examine how intravenous cocaine at a behaviorally active dose affects extracellular glucose levels in the nucleus accumbens (NAc), a critical structure within the motivation-reinforcement circuit. In drug-naive rats, cocaine induced a bimodal increase in glucose, with the first, ultra-fast phasic rise appearing during the injection (latency 6–8s; ∼50μM or ∼5% of baseline) followed …

Role Of The Α1 Blocker Doxazosin In Alcoholism: A Proof-Of-Concept Randomized Controlled Trial, George A. Kenna, Carolina L. Haass-Koffler, William H. Zywiak, Steven M. Edwards, Michael B. Brickley, Robert M. Swift, Lorenzo Leggio

Department of Psychology: Faculty Publications

Evidence suggests that the norepinephrine system represents an important treatment target for alcohol dependence (AD) and the α1-blocker prazosin may reduce alcohol drinking in rodents and alcoholic patients. The α1-blocker doxazosin demonstrates a more favorable pharmacokinetic profile than prazosin, but has never been studied for AD. A double-blind placebo-controlled randomized clinical trial was conducted in AD individuals seeking outpatient treatment. Doxazosin or matched placebo was titrated to 16 mg/day (or maximum tolerable dose). Drinks per week (DPW) and heavy drinking days (HDD) per week were the primary outcomes. Family history density of alcoholism (FHDA), severity of AD and gender were …

A Dream Best Forgotten: The Phenomenology Of Karen Refugees’ Pre-Resettlement Stressors, Theodore T. Bartholomew, Brittany E. Gundel, Neeta Kantamneni

Department of Educational Psychology: Faculty Publications

Refugees are often forced into states of imposed vulnerability in which loss is common and migration is normative. Karen refugees from Myanmar have endured a long civil war with the Burmese government, followed by their forced relocation to refugee camps and subsequent global resettlement. This phenomenological study aimed to understand the meanings ascribed to pre-resettlement stress among resettled Karen refugees. We interviewed six participants who were identified through purposeful sampling in a Karen refugee community. Using phenomenological analysis, we identified and interpreted 286 meaning units. The meaning units were then grouped into four themes: (a) Loss From Oppression, (b) Resignation …

Spirituality, Religious Coping, And Depressive Symptoms In Hospice Patients: A Terror Management Perspective, Janine Siegel

Walden Dissertations and Doctoral Studies

Facing imminent death can be an unremitting problem for hospice patients who lack psychological support for existential concerns that contribute to depressive symptoms and suffering. According to terror management theory, spiritual and religious beliefs are a common means of coping with mortality at the end of life, and few studies have considered how hospice patients feel about their impending death. This was a quantitative, cross-sectional study that examined whether spirituality and religious coping moderated the relationship between imminent death concerns and depressive symptoms in 54 hospice patients. Participants completed a self-administered survey that included the Templer Death Anxiety scale, Brief …

Computer Anxiety And Computer Self-Efficacy Of Older Adults, Elizabeth Diane Cooper-Gaiter

Walden Dissertations and Doctoral Studies

Many older adults (aged 55 and older) need training to acquire computer knowledge and skills. Using computers and the Internet could provide access to vital resources for improving older adults' health and maintaining their connections with family and society. This study examined 2 psychological constructs--computer anxiety and computer self-efficacy--that have been shown to impact a person's successful use of computers and related technology. Guided by Bandura's self-efficacy theory, which emphasizes the importance of adult learners being motivated and taking charge of their learning, this study examined the impact of a computer knowledge and skills workshop on older adults' computer anxiety …

Utilizing The Rorschach In Analyzing Characteristics Of Women Who Have Experienced Domestic Violence, Mary Aleksandra Iwanski

Walden Dissertations and Doctoral Studies

Intimate partner violence (IPV) affects millions of women, men, and families throughout the world each year, with more than a million incidents of domestic partner abuse reported to law enforcement officials each year in the United States. Being able to accurately assess and help a woman who is experiencing this type of violence can be difficult for even a seasoned mental health or medical professional. The purpose of this study was to determine whether clinicians can gain insight into the personality structure of women who have experienced IPV by clinical interview and administration of the Rorschach alone. This study analyzed …

The Effects Of Frequent Exposure To Violence And Trauma On Police Officers, Ternarian A. Warren

Walden Dissertations and Doctoral Studies

Police officers who maintain negative or traumatic information in long-term memory are vulnerable to mental illness, unstable emotional and behavioral responses, interpersonal problems, and impaired social relationships. The cognitive theory suggests that police officers externalize various negative or maladaptive behaviors as a result of frequent exposure to traumatic events. Researchers have found that police officers tend to either not seek mental health treatment, try to fix their own mental health problem, or if in treatment will not be forthcoming with internalized thoughts of psychological distress. The intention of this research was to examine the relationship between police officers' frequent exposure …

Women’S Experiences Of Pregnancy Loss: An Interpretative Phenomenological Analysis, Esther Lea Kint

Theses: Doctorates and Masters

Over the past three decades, research has proliferated on the incidence of grief severity following pregnancy loss, with many research studies citing the existence of ‘complicated’ and ‘unresolved’ grief. It is argued that this emphasis on grief severity has overshadowed other aspects of the bereavement experience that might differ from grief as it has been defined. Understanding the experience of loss in pregnancy instead of categorising it, would allow for new and varied understandings of the meaning women attribute to their experience of losing a baby. Furthermore, paying attention to women’s interpretations and understandings of pregnancy loss provides valuable insight …

A Model For Measuring The Contribution Of Form To Perception Of Biological Sex In Point-Light Actors, Michael Mintz

Dissertations and Theses @ UNI

People are able to judge the sex of actors represented in point-light displays. Much of the previous literature has focused on the contribution of motion information to this judgment, or has focused specifically on information gathered from the shoulders and hips. The purpose of the current study is to model how form information, based upon the distance between the dots representing a point-light actor’s key joints, the shoulder, hip, elbow, knee, wrist, and ankle points, contributes to the perception of biological sex. In a pilot study, 6 naïve observers responded to 63 computer generated stimuli that ranged from extremely female …

School District Stress Prevention Practices In A Southern U.S. State, Stephen Field Keohane

Walden Dissertations and Doctoral Studies

The growing recognition that stress is a risk factor for youth health problems has spawned research on school-based stress prevention programs and services. While such programs and services are now available for adoption by schools, there is an absence of data on their use in U.S. schools systems. In the current study, Everett Rogers's diffusion of innovations model provided the theoretical framework for the investigation of school district stress prevention practices in one southern U.S. state. The sample for this quantitative descriptive study consisted of 135 out of 136 active public districts, and 72% of school systems completed and returned …

Best Predictors Of A Person's Long-Term Success With Quitting Tobacco, Nhu-Tam P. Villar

Walden Dissertations and Doctoral Studies

Smoking relapse rates among tobacco users remain high after quit attempts, with or without interventions. Though researchers have examined stress-related factors contributing to high relapse rate, little empirical research has concentrated on variables predicting long-term quit maintenance. The purpose of this study was to determine the predictability of stress management tools, including exercise motivation, eating behaviors, social support, and self-compassion, as well as the significant combined variance of these variables, in a person's long-term maintenance with tobacco use abstinence. Bandura's social cognitive theory was used to highlight the factors contributing to health behavior such as tobacco use. This study involved …

Personality Traits Associated With Environmental Concern, Tara Rae Wuertz

Walden Dissertations and Doctoral Studies

The 5 factor model of personality, including the traits of openness, conscientiousness, extraversion, agreeableness, and neuroticism, is a well-established theoretical model for describing how personality is structured. Hirsh (2010) demonstrated the big 5 personality traits, excluding extraversion, were correlated with pro-environmental attitudes. The purpose of this quantitative study was to replicate previous findings, and discover if there was a correlation with a person's pro-environmental behaviors and the big 5 personality traits. A total of 100 participants from an online participant pool completed a survey, which included the Environmental Concern Scale to measure concern and attitudes about the environment, and the …

A Mindfulness-Based Stress Reduction Psychoeducational Program In Postpartum Support Groups, Marina Pesserl

Walden Dissertations and Doctoral Studies

Postpartum Depression (PPD) affects 15% of women after childbirth. Its etiology includes psychoneuroimmunologic factors with long-lasting postpartum stressors that lead to allostatic overload. Using mindfulness-based stress reduction (MBSR) for PPD has not yet been studied. Addressing this literature gap, the potential benefits of including an 8-week MBSR component based on Beck's theory of PPD at support groups were examined in this phenomenological study based on a sample of 10 women and 2 group facilitators. Purposes of the study included describing the experience of PPD and the MBSR program, identifying the stage of behavioral change of the participants, and describing the …

Learned Helplessness And Depression: Comparison Of Skilled Nursing And Assisted Living Facilities, Paul Lynn Susic

Walden Dissertations and Doctoral Studies

Research with geriatric populations suggests high levels of clinical depression and greater financial and psychological costs of treatment in long-term care facilities with more restrictive care. Research on learned helplessness, a construct separate from depression, suggests learned helplessness and perceived control are useful theories for the study of elder depression, but the relationship between depression and learned helplessness in this population is not clear. This cross-sectional quantitative study examined the relationship between depression and learned helplessness by comparing residents over age 65 in less restrictive assisted living (n =42) versus those in more restrictive skilled nursing facilities (n =63). Data …

Gender-Homogenous Mentoring, Spiritual Wellbeing, And Self-Efficacy Beliefs In African American Male Adolescents: A Test Of Three Models, Toussaint David Whetstone

Dissertations

Many African American male adolescents mature without the influence of an adequate social model, or a positive, same sex (or gender-homogenous) mentor. Thus, it may be difficult for African American male adolescents to reach adulthood having developed the perceived capability to be successful within specific domains that American society commonly associates with a healthy life course trajectory. A large body of research has suggested that vicarious experience or role modeling is a primary source of efficacy information in a variety of life domains. Research has also suggested that modeling effects are enhanced if the subject and model are similar, especially …

Why Some Women Eat Too Much: A Qualitative Study Of Food-Dependent Women, Gigi Van Ostrand

Walden Dissertations and Doctoral Studies

Obesity has become a worldwide epidemic and limiting one's food intake, or dieting, is usually unsuccessful. The purpose of the study was to explore the effect of food addiction (FA) on the current clinical and behavioral epidemic of obesity. FA, synonymous with food-dependency, is tentatively defined as an eating disorder based on substance dependence, as defined by the Diagnostic and Statistical Manual of Mental Disorders. Measurement of FA has been operationalized by the Yale Food Addiction Scale (YFAS) by applying the diagnostic criteria of substance dependence to eating behaviors. This study was based on the biological theory of chemical addiction …

Behavioral Effects Of Fluoxetine On Aggression And Associative Learning In Betta Splendens, Benjamin Eisenreich

Graduate Student Theses, Dissertations, & Professional Papers

While the link between serotonin and the behaviors of aggression and learning has been elucidated, few studies have examined the impact serotonin has on learning for aggressive rewards. In particular, the SSRI fluoxetine has been demonstrated to reduce aggression as well the acquisition of instrumental responding for rewards indicating that this drugs behavioral effect may be related to motivational processes important for learning. To examine the relationship between fluoxetine and motivational process important for learning, two experiments were conducted using Betta splendens, a species well known for their robust aggressive response and drive to engage in aggressive behaviors, to examine …

An Examination Of Social Desirability Confounds In A New Ipsative Measure Of Murray's Psychogenic Needs, Lisa Harris

Theses: Doctorates and Masters

A reliable and valid instrument for the direct measurement of the relative strength of psychological needs is currently lacking. In response to this shortcoming, a new ipsative instrument, the Psychogenic Need Scale (PNS), is currently being developed; this is a 190-item forced-choice self-report measure that is based upon Murray’s psychogenic needs. For the development of a valid forced-choice instrument, it is critical to minimise the confounding effects of social desirability (the tendency for respondents to describe oneself in the most favourable light). Whilst other measures typically use specifically designed scales to detect social desirability confounds, this approach is unsuitable for …
