Embodied Co-Regulation: A Neuroregulatory-Informed Dance/Movement Therapy Transition Intervention Method For Arousal Regulation For Adolescents In A Partial Hospitalization Program, Anamaria Guzman

Expressive Therapies Capstone Theses

This thesis introduces a novel Dance/Movement Therapy (DMT) approach, focusing on nervous system arousal regulation during transitions between therapy groups. The core of the method involves a brief 5-minute exercise designed to modulate arousal levels, encompassing alertness and energy, aiming to establish a baseline homeostasis. Rooted in Polyvagal Theory and Developmental Neurobiology, the approach assumes the co-regulation of nervous systems within a group therapeutic setting. Two primary outcomes are self-assessed: 1) somatic experiences documented through narratives and 2) nervous system biodata measured using the Flowtime headband monitoring of brainwaves, heart rate, and other biomarkers. Results indicated that all six sessions …

Walden Dissertations and Doctoral Studies

Unethical organizational behavior negatively impacts organizations, and despite the benefits of whistleblowing, some employees are hesitant to report employee misconduct. The specific research problem examined factors that influence employee silence when confronted with employee misconduct. Prior researchers have explored how organizational climate and organizational commitment can contribute to or inhibit the decision to report misconduct. What remained unclear is how these factors may interact on their influence on employee silence. The purpose of this study was to examine whether organizational commitment mediated the relationship between organizational climate and employee silence. The theoretical foundations for this study were the social information …


The Impact Of Levodopa Administration On Learning From Short-Term And Long-Term Action Consequences: A Paradigm Validation., Masood Rezaei Oct 2020

The Impact Of Levodopa Administration On Learning From Short-Term And Long-Term Action Consequences: A Paradigm Validation., Masood Rezaei

Electronic Thesis and Dissertation Repository

Behavioral and neuroimaging studies have identified two valuation systems in the human brain for controlling behavior known as model-free (MF) and model-based (MB). MF is based on immediate evaluation and MB is based on long-term evaluation of the outcome of our decisions. Previous studies suggest that dopamine baseline activity may play an important role in the balance between the two systems and determine how they compete or interact in controlling our actions. The overarching aims of this study is to investigate the impact of levodopa administration on learning from immediate and long-term action consequences, and to dissociate the role of …

Atheoretical Versus Theory-Based Approaches In Promoting Safer Adhd-Medication Prescribing For Adults, Kathleen A. Fairman Jan 2020

Atheoretical Versus Theory-Based Approaches In Promoting Safer Adhd-Medication Prescribing For Adults, Kathleen A. Fairman

Walden Dissertations and Doctoral Studies

Gaps between treatment guidelines and medical decisions persist despite interventions with physicians, which are mostly atheoretical. The purpose of this retrospective cross-sectional study was to compare atheoretical and theory-based logistic regression models of a binary outcome: potentially unsafe prescribing of attention-deficit hyperactivity disorder (ADHD) medications to adults. Social cognitive theory and self-determination theory provided the framework for the study. Predictors were framed as social cognitive theoretical constructs: knowledge (e.g., physician specialty) and environmental influence (e.g., interventions). Atheoretical hypotheses were based on legislation mandating meaningful use of electronic health records and computerized decision support (CDS). Theory-based hypotheses were derived from literature …


An Examination Of Social Connectedness On Ptsd And Freezing In A Student Military Population, Jessica Marie Ledwith Jan 2020

An Examination Of Social Connectedness On Ptsd And Freezing In A Student Military Population, Jessica Marie Ledwith

UNF Graduate Theses and Dissertations

This study investigates the impact of social connectedness (SC) and post-traumatic stress disorder (PTSD) in a military college population, and their relation to physiological measures such as body sway, heart rate (HR), and heat rate variability (HRV). According to previous research, people with PTSD are more likely to exhibit a freezing response to affective images. In the present study, we explore the potential freezing response for military personnel at the levels of PTSD symptom groups and social connectedness. We also investigate the possible buffering effect social connectedness has on the outcome of PTSD and freezing. There was a total of …


Fight, Flight, Or Freezing? Investigating The Immobility Response In Military Veterans, Paige Elizabeth King Jan 2020

Fight, Flight, Or Freezing? Investigating The Immobility Response In Military Veterans, Paige Elizabeth King

UNF Graduate Theses and Dissertations

When the body is faced with threat to life or limb, the autonomic nervous system works to overcome the danger – by either fight, flight, or freezing. While immobility may not appear to be the most logical solution, theories exist that it allows for judgement of the situation and preparation for action. This study investigated the stress response that military veterans, with or without post-traumatic stress disorder (PTSD), demonstrate when shown unpleasant images. Researchers wanted to determine the extent to which veterans would show freezing or immobile responses when under an unpleasant image condition. It was hypothesized that veterans who …

Stress, Social Support, And Mindfulness In Parents Of Children With Neurodevelopmental Deficits: A Quantitative Analysis, Branden D. Syrotchen

Walden Dissertations and Doctoral Studies

Parenting children with neurodevelopmental deficits (NDDs) is very stressful, more so than the parenting of typically developing children. There is considerable research on the topic of chronic stress experienced by caregivers; however, less is understood of parental stress experienced when raising children with NDDs. The purpose of this study was to examine how parental traits and habits, in the forms of mindfulness and social support levels, affect this cohort's general stress levels. The study was guided by Self-Determination Theory, which explored how parental acts could be classified along a continuum of being intrinsically or extrinsically derived. A convenience sample of …

Surgical Perioperative Leadership: The Association Between Leadership Style And Team Job Satisfaction, Corey Louise Jamison Jan 2019

Surgical Perioperative Leadership: The Association Between Leadership Style And Team Job Satisfaction, Corey Louise Jamison

Walden Dissertations and Doctoral Studies

Abstract

The perioperative operating room (OR) is a highly complex, fast-paced environment where countless transactions must be executed with efficiency, speed, and accuracy, and where mistakes of any kind could lead to adverse patient outcome, injury, or death. The surgeon, as leader of the procedure and the OR team, sets the overall climate of the OR and determines how willing (or unwilling) team members are to speak up about potential errors or unsafe patient conditions. This exploration of the relationship between perioperative surgeon leadership style and OR team member job satisfaction fills a gap unaddressed in the literature using items …


Examining Fear Of Recurrence In Cancer Survivors, Christina L. Dixon Jan 2019

Examining Fear Of Recurrence In Cancer Survivors, Christina L. Dixon

Walden Dissertations and Doctoral Studies

Improvements in the medical field have given many cancer patients and survivors better odds of long-term survival. As more patients become survivors, the demand for psychological treatment becomes greater. The most prevalent concern of survivors is getting help with a psychosocial condition known as fear of recurrence (FOR). Prior to this study, few researchers had explored how having a more aggressive cancer influences the development of FOR. The purpose of this quantitative study was to determine whether cancer stage and type (a measurement of severity) are predictive of FOR development in the high-risk cancer groups lung and bronchus and female …

Neurobehavioral Measurements Of Natural And Opioid Reward Value, Aaron Paul Smith Jan 2019

Neurobehavioral Measurements Of Natural And Opioid Reward Value, Aaron Paul Smith

Theses and Dissertations--Psychology

In the last decade, (non)prescription opioid abuse, opioid use disorder (OUD) diagnoses, and opioid-related overdoses have risen and represent a significant public health concern. One method of understanding OUD is as a disorder of choice that requires choosing opioid rewards at the expense of other nondrug rewards. The characterization of OUD as a disorder of choice is important as it implicates decision- making processes as therapeutic targets, such as the valuation of opioid rewards. However, reward-value measurement and interpretation are traditionally different in substance abuse research compared to related fields such as economics, animal behavior, and neuroeconomics and may be …


A Laboratory-Based Experimental Test Of Reasons For Living: Effects On Behavioral Approach Toward A Suicide-Related Stimulus, Sasha Micaella Rojas May 2018

A Laboratory-Based Experimental Test Of Reasons For Living: Effects On Behavioral Approach Toward A Suicide-Related Stimulus, Sasha Micaella Rojas

Graduate Theses and Dissertations

There are few laboratory-based experiments that examine the effects of suicide-related risk or protective factors on suicide-related outcomes. Consistent with extant evidence-based theoretical models and treatments for suicidal behavior, it appears that increasing awareness of reasons for living may reduce risk for suicidal behavior. Thus, the current study represents an initial effort to experimentally examine the impact of bringing awareness to one’s most important reason for living on behavioral approach towards a suicide-related stimulus. Random assignment was used to assign an unselected undergraduate sample of 78 participants to complete either a script-driven imagery procedure specific to the most important reason …


Assessing The Ordinality Of Response Bias With Item Response Models: A Case Study Using The Phq-9, Venessa N. Singhroy May 2018

Assessing The Ordinality Of Response Bias With Item Response Models: A Case Study Using The Phq-9, Venessa N. Singhroy

Dissertations, Theses, and Capstone Projects

Improper scale usage in psychological and clinical assessment is an important problem. If respondents do not use the scales in a consistent manner, the reliability of a composite is likely to be attenuated. This is particularly problematic when particular items are singled out for special treatment or when subscales are of interest, not just a total score. This study used both non-parametric and parametric item response theory (IRT) methods to gain further insight into the validity of the PHQ-9, a dual purpose instrument that assesses the severity of depressive symptoms using nine Likert-scale items and allows the investigator to establish …

Amputee Social Support: A Quantitative Investigation Of Peer-To-Peer And Group Influence, Dirrick Anthony Williams Jan 2018

Amputee Social Support: A Quantitative Investigation Of Peer-To-Peer And Group Influence, Dirrick Anthony Williams

Walden Dissertations and Doctoral Studies

Previous research has indicated that vascular disease, trauma, and cancer lead to amputations and that 1.7 million Americans are living with an amputation. The social problem of this study is that amputees have limited places to obtain social support. Alderfer's Existence, Relatedness, and Growth Theory provided the foundation for this research. The current study examined the following questions. First, does type of social support impact amputee perceived social support satisfaction? Second, does type of social support impact life satisfaction? Survey methodology was used following attendance at either peer-to-peer or group support. A purposeful sample of 184 participants were assessed using …


Sexism, Just-World Beliefs, And Defensive Attribution: Relationship To Online Discourse And Child Sexual Abuse, Andrea M. Barbis Jan 2018

Sexism, Just-World Beliefs, And Defensive Attribution: Relationship To Online Discourse And Child Sexual Abuse, Andrea M. Barbis

Walden Dissertations and Doctoral Studies

Research has shown that individuals' willingness to believe a disclosure of childhood sexual abuse (CSA) is related to just-world beliefs, ambivalent sexism, and defensive attribution. However, researchers do not know whether these variables relate to posts made in response to online articles describing CSA. Negative or disbelieving posts may impact not only the author, but also readers who view these comments via hindrance of disclosures, increased self-blame, and avoidance of help seeking. In this quantitative study, just-world, ambivalent sexism, and defensive attribution theories provided the theoretical basis used to determine whether just-world beliefs, ambivalent sexism, and defensive attribution influenced comments …


Black Individuals' Lived Experiences With Racial Microaggressions And Implications In Counseling, Letitia V. Browne-James Jan 2018

Black Individuals' Lived Experiences With Racial Microaggressions And Implications In Counseling, Letitia V. Browne-James

Walden Dissertations and Doctoral Studies

The problem of racial microaggressions in the United States has important implications for counseling due to the mental and physical health concerns individuals who experience them may develop. Although the current literature addresses racial microaggressions among Black individuals and implications for counseling, no qualitative studies that included the voices of Black individuals using relational cultural theory were found. Therefore, the purpose of this study was to explore the lived experiences of Black individuals who have encountered racial microaggressions and learn their perspectives on what counselors can do to help them in counseling.

Holistic Health And Hawaii's Renewable Energy Future, Richard M. Esterle Jan 2018

Holistic Health And Hawaii's Renewable Energy Future, Richard M. Esterle

Walden Dissertations and Doctoral Studies

Collective efficacy, time urgency, and health literacy have been a focus of research since the 1970s. Researchers have demonstrated that these factors influence health and decision making. However, researchers have yet to establish how these factors may be connected to the achievement of policy aims that impact holistic or environmental health. This study utilized the health belief model, social cognitive theory, time urgency theory, health education and promotion theory, Bronfenbrenner's ecological systems theory, and the Meikirch model. The purpose of this quantitative study was to determine if the factors of collective efficacy, perceived time urgency, perceived health literacy, ethnicity, age, …

Individual Understanding Of The Risks Associated With Polypharmacy, Michelle Patricia Mchenry

Walden Dissertations and Doctoral Studies

With many individuals experiencing multimorbidity, individuals are being prescribed more medications. Although there are benefits to taking medications to manage symptoms and treat disease processes, there are also risks to taking multiple medications. The purpose of this phenomenological study was to explore participants' understanding of the risks associated with practicing polypharmacy. Game theory, credibility theory, and belief bias were the conceptual frameworks used to explain how individuals experienced their care and being prescribed 5 or more medications. Eight participants residing in subsidized housing in a small Midwest city, who were taking 5 or more medications volunteered to take part in …
