Exploring Primary Care Providers’ Compassionate Care And Their Evidence-Based Practice With Death, Grief, And Loss: Patient Experience And Perspective, Kathryn Krzykala

Dissertations

Research on primary care providers’ (PCPs) education regarding Death, Grief, and Loss (DGL) remains limited. Specifically, data is lacking regarding patients' perceptions and opinions on what they need and expect from their PCPs regarding grief and loss. This exploratory mixed-method study comprised 146 participants who had experienced death and non-death loss. It examined participants' perceptions of 1) PCP compassion, 2) PCP utilization of evidence-based grief and loss practices, 3) their own level of comfort discussing DGL with their PCPs during medical visits, and 4) their personal grief and loss experiences. The findings revealed that PCPs' grief-informed evidence-based treatment, as reflected …

Children and Families

Bullying remains a significant public health and educational concern worldwide and is particularly prevalent in Philippine public schools, with Grade 7 students identified as a vulnerable group. Although the Anti-Bullying Act of 2013 (Republic Act No. 10627) mandates school-based policies and procedures, persistent implementation gaps underscore the need to strengthen home–school partnerships and equip parents with practical, culturally grounded response strategies. This paper describes the development of the Da Mosang Tarsier Series, a set of digital psychoeducational comic strips designed for Filipino parents of Grade 7 students. Guided by a user-centered design (UCD) framework, the project began with a Generative …


Influence Of Self-Reported Maternal Mental Health Diagnosis And Parenting Practice On Child Externalizing Behavior, Caitlin E. Smith Jul 2026

Influence Of Self-Reported Maternal Mental Health Diagnosis And Parenting Practice On Child Externalizing Behavior, Caitlin E. Smith

All-Inclusive List of Electronic Theses and Dissertations

Maternal psychopathology generally has been associated with greater likelihood of childhood pathology (e.g., Bellina et al., 2020) which is likely due to both genetic (e.g. heritability of mental health diagnoses) and environmental (e.g., parenting) influences. ADHD, in particular, is a disorder with a high heritability rate (Kuja-Halkola et al., 2015). Other parent mental health difficulties, such as anxiety or depression, can also influence parenting behavior as well as child behavior. Broadly, maternal psychiatric history is related to child ADHD symptom severity (López Seco et al., 2015). Positive parenting may be especially important when parenting a child with ADHD as positive …

Background: Posttraumatic stress disorder (PTSD) is a mental disorder that may occur in the aftermath of severe psychological trauma. Epigenetic changes in the brain may play a critical role in understanding the neurobiology of PTSD by linking environmental traumatic stress exposure to lasting alterations in gene expression that shape neuronal function.

Methods: We examined 1,065,750 DNA methylation (DNAm) sites from 171 donors including neurotypical controls and PTSD and major depressive disorder (MDD) cases across 6 regions implicated in the fear circuitry of the brain. We performed RNA sequencing (RNA-seq) to examine changes in gene expression and linked these changes to …

Using Contingency Mapping To Decrease Disruptive Behavior And Increase On-Task Behavior For Students With Autism Spectrum Disorder, Carelis Y. Pabey Pagan Jun 2026

Using Contingency Mapping To Decrease Disruptive Behavior And Increase On-Task Behavior For Students With Autism Spectrum Disorder, Carelis Y. Pabey Pagan

USF Tampa Graduate Theses and Dissertations

Visual aids have been widely used in educational and therapeutic settings to support individuals with developmental disabilities, particularly autism spectrum disorder (ASD). Among these, contingency maps, a graphic tool that visually represents the outcomes of alternative behaviors and problem behavior, have shown promise in reducing problem behavior, increasing communication, and promoting independence. However, existing research on contingency mapping is limited. The proposed study extended this literature by evaluating the effects of contingency maps on academic engagement and disruptive behavior for children with ASD in a school setting during natural classroom activities. A multiple baseline design across participants was used to …

The Prevalence Of Moral Injury Among Veterans Diagnosed With Post-Traumatic Stress Disorder (Ptsd): Analyses By Combat Exposure, Gender, Age Group, And Military Service, Carl B. Forkner Jun 2026

The Prevalence Of Moral Injury Among Veterans Diagnosed With Post-Traumatic Stress Disorder (Ptsd): Analyses By Combat Exposure, Gender, Age Group, And Military Service, Carl B. Forkner

Doctoral Dissertations and Projects

The attacks on the United States on September 11, 2001, and the ensuing wars in Afghanistan and Iraq, heralded in a new concept affecting our combat and support military personnel. This concept is known today as moral injury. Military personnel were already familiar with post-traumatic stress disorder (PTSD), whether from personal experience or from reading and training on the subject, but no training addresses the prevalence or effects of moral injury. The term moral injury (MI) was first coined by psychiatrist Jonathan Shay and his colleagues based on feedback from military and veteran patients in 1998; however, it remains that …

The Relationship Between Estimated Vo2max And Poor Mental Health: A Study Of Brfss Data, Angelina Somadina Oputa

Doctoral Dissertations and Projects

Mental health conditions are one of the leading contributors to the global burden of disease. Despite advancements in mental health therapies and psychiatric medications, significant numbers of patients continue to struggle with mental illness. Despite these challenges, exercise can serve as a powerful tool to address mental health concerns. Current literature has referenced the value of physical fitness to support mental health, however there is limited large-scale research assessing the estimated maximal oxygen uptake (VO2Max) as a predictor of poor mental health days. In response, this quantitative secondary analysis was conducted to examine the relationship between estimated VO2Max and poor …


A Caveat Regarding The Unfolding Argument: Implications Of Plasticity, Viknas N. O'Reilly-Shah, Alessandro Maria Selvitella, Aaron Schurger Jun 2026

A Caveat Regarding The Unfolding Argument: Implications Of Plasticity, Viknas N. O'Reilly-Shah, Alessandro Maria Selvitella, Aaron Schurger

Psychology Faculty Articles and Research

The unfolding argument in the neuroscience of consciousness posits that causal structure cannot account for consciousness because any recurrent neural network (RNN) can be “unfolded” into a functionally equivalent feedforward neural network (FNN) with identical input–output behavior. Subsequent debate has focused on dynamical properties and philosophy of science critiques. We examine a boundary condition on the unfolding argument for RNN systems with rapid plasticity in their connection weights. We demonstrate through rigorous mathematical proofs that rapid plasticity negates the functional equivalence between the RNN and the FNN. Our proofs address history-dependent plasticity, dynamical systems analysis, information-theoretic considerations, perturbational stability, complexity …

Using In-Home Air Quality Monitoring To Reduce Cannabis Secondhand Smoke Exposure In Children: Quantitative Pilot Feasibility Study, Vincent Berardi, Bradley N. Collins, Laura M. Glynn, Eusabeia Silfanus, Darby G. Lyons, Stephen J. Lepore

Psychology Faculty Articles and Research

Background: An estimated 5 to 8 million US children live with a parent who uses cannabis, and most cannabis users report smoking cannabis inside their homes, placing children at risk for cannabis secondhand smoke (cSHS) exposure. Indoor air quality (IAQ) monitoring provides real-time feedback on airborne pollutants and has shown promise in reducing in-home tobacco secondhand smoke exposure, suggesting its potential as an effective harm reduction strategy for cSHS.

Objective: This pilot study evaluated the feasibility, acceptability, and preliminary effectiveness of using low-cost, off-the-shelf IAQ monitors to increase caregivers’ awareness of children’s cSHS exposure risk and to change …


(Re)Claiming Homeplace: Dance As Embodied Resistance & Healing For Health & Spatial Justice, Preeya G. Kannan Jun 2026

(Re)Claiming Homeplace: Dance As Embodied Resistance & Healing For Health & Spatial Justice, Preeya G. Kannan

University Honors Theses

This thesis argues that dance functions as both an upstream public health intervention and a form of radical spatial resistance; creating healing, agency, and belonging among historically marginalized communities. Drawing on bell hooks' concept of homeplace, Jasbir Puar's assemblage theory, Nancy Krieger's eco-social theory, and Katherine McKittrick's Black geographies, I position the body as both an ecological and political landscape shaped by histories of colonialism, racial capitalism, displacement, and resilience.

Through this community-based participatory research study, Homeplace, I explore dance as a form of social prescription that centers liberation rather than pathology. Movement is often reduced in public health discourse …


Determinants Of Corporal Punishment And Severe Physical Punishment In Egypt: A Mixed-Methods Analysis For Child Protection Policy, Marwa Moustafa Nassef Jun 2026

Determinants Of Corporal Punishment And Severe Physical Punishment In Egypt: A Mixed-Methods Analysis For Child Protection Policy, Marwa Moustafa Nassef

Theses and Dissertations

Corporal punishment (CP) and severe physical punishment (SPP) remain a major public health, child rights, and child protection policy concern. In Egypt, despite legislative reforms, survey-weighted analysis of the 2021 Egypt Family Health Survey (EFHS) 2021 (CAPMAS, 2022) reveals prevalence rates of 60.5% for CP and 27.4% for SPP among children aged 1–14 (author’s calculations using EFHS-2021, n=7623), yet evidence distinguishing the determinants of routine corporal punishment from escalation to severe physical punishment remains limited in low- and middle-income contexts. Guided by Bronfenbrenner’s ecological framework, this mixed-methods study identifies key drivers of CP and its escalation to SPP among Egyptian …

Nutritional Neurocriminology Today

Although often difficult to discuss with clients, gastrointestinal (GI) issues affect an estimated 60 to 70 million Americans (American Gastroenterological Association, 2022). Yet only about 25% of those experiencing these conditions receive treatment. This is troubling because GI issues frequently co-occur with clinically significant consequences for physical health, psychological well-being, daily functioning, and overall quality of life. Designed for behavioral health and healthcare professionals, this brief article introduces the field of psychogastroenterology, with emphasis on symptoms, stigma, diagnosis, and treatment. Key topics include the gut-brain axis, common digestive health conditions, and the mental health implications associated with gastrointestinal disorders.


Seizure-Induced Resolution Of Depressive And Psychotic Symptoms In A Pregnant Patient: A Case Of Spontaneous Neuromodulation, Ariel E. Sosa Gomez, Ryan M. Go, David Valdez Jun 2026

Seizure-Induced Resolution Of Depressive And Psychotic Symptoms In A Pregnant Patient: A Case Of Spontaneous Neuromodulation, Ariel E. Sosa Gomez, Ryan M. Go, David Valdez

School of Medicine Publications

Many individuals with epilepsy often develop major depressive disorder (MDD), creating a complex interplay that exacerbates outcomes for affected individuals. The relationship between these disorders may be mediated by overlapping neurobiological mechanisms, including disturbances in the limbic system, neurotransmitter imbalances, and the psychosocial stressors of chronic illness. While the co-occurrence typically leads to a worsening of symptoms, rare instances have been reported in which seizure activity appears to ameliorate psychiatric symptomatology. We present the case of a 23-year-old pregnant Hispanic female with a longstanding history of treatment-resistant depression with psychotic features and epilepsy, who demonstrated full remission of depressive and …

An Exploratory Study: The Presence Of Imposter Syndrome In New Graduate Allied Health Professionals And Its Relationship To Location Of Practice, Samantha J. Barber, Carol A. Flavell Dr, Moira Smith Dr Jun 2026

An Exploratory Study: The Presence Of Imposter Syndrome In New Graduate Allied Health Professionals And Its Relationship To Location Of Practice, Samantha J. Barber, Carol A. Flavell Dr, Moira Smith Dr

Internet Journal of Allied Health Sciences and Practice

Purpose: Imposter syndrome (IS) explores the feelings of fraudulence within personal and professional settings. Commonly IS results in impaired self-confidence, and self-perceptions of one’s own abilities, their mental health, and places them at a higher risk of burnout. Imposterism is linked to transitionary periods, such as being newly graduated, and while IS addressed amongst the medical community [doctors and nurses], there is a gap in literature relating to IS amongst allied health professionals (AHPs). Additionally, there is no known literature in which IS presence or severity is explored in relation to an individual’s geographic location. The aim of this study …


Fentanyl Mediated Distortions Of Phasic Dopamine Release Dynamics Encoding Natural Reward And Aversive Processing In The Mammalian Mesolimbic Circuit, Oliver P. Culver Iv Jun 2026

Fentanyl Mediated Distortions Of Phasic Dopamine Release Dynamics Encoding Natural Reward And Aversive Processing In The Mammalian Mesolimbic Circuit, Oliver P. Culver Iv

MUSC Theses and Dissertations

Mu opioid receptor (MOR) agonists are recognized to disinhibit tonic dopamine (DA) in the ventral striatum (VS), contributing to opioid addiction and euphoria. However, MOR agonists can also inhibit non-drug reward-seeking, and disrupt conditioned responding to aversive stimuli, a phenomenon not readily explained by tonic DA disinhibition. We hypothesized that this effect could be due in part to disruption of phasic DA responses to conditioned stimuli (CS) which critically shape and maintain behaviors during naturalistic reward and aversive processing. Because MOR effects on CS-evoked phasic DA are largely unexamined, we conducted in vivo fiber photometric recordings in water-deprived male and …


Evaluating Behavioral Intervention Strategies For Reducing Hyperactivity In Children Diagnosed With Autism Spectrum Disorder And Comorbid Adhd, Murtadha M. Abd Noor, Dunya Habeeb Shnain Jun 2026

Evaluating Behavioral Intervention Strategies For Reducing Hyperactivity In Children Diagnosed With Autism Spectrum Disorder And Comorbid Adhd, Murtadha M. Abd Noor, Dunya Habeeb Shnain

Maaen Journal for Medical Sciences

One of the most difficult and complex symptoms in children with autism spectrum disorder (ASD) and comorbid attention deficit hyperactivity disorder (ADHD) is hyperactivity. This has a substantial negative impact on daily functioning, learning, and responsiveness to therapy interventions, as well as on intervention programs that aim to manage behavior in schools and clinical settings, thereby restricting children's engagement in these programs as management behaviors become more emphasized. Given marked heterogeneity in clinical presentations and a lack of consensus on the most effective behavioral strategies, there remains an imperative to systematically evaluate targeted, specific strategies for reducing hyperactivity in this …


Understanding And Enhancing Suicide Prevention Strategies In The Military: The Roles Of Culture, Leadership, And Command Climate, Kelly Johanna Pires Jun 2026

Understanding And Enhancing Suicide Prevention Strategies In The Military: The Roles Of Culture, Leadership, And Command Climate, Kelly Johanna Pires

Dissertations

Military service members are shaped and molded to fit a military culture that emphasizes mission readiness and continuous preparedness. Countless hours are spent training for various situations that can arise. Many trainings are geared toward worst-case scenarios that can cause an increase in stressors and traumatic events. They are expected to demonstrate resilience and overcome adversity to remain mission-ready. This expectation to be mission-ready creates the space for mental health difficulties as well as stigma and avoidance of help-seeking behaviors. In many cases, the desire to stay mission-ready creates a barrier for conversations around mental health. The military emphasizes qualities …

A Predictive Coding Account Of Spatial Working Memory Following Prophylactic Levetiracetam Administration Prior To Traumatic Brain Injury, Omeima Mutwali

Dissertations, Theses, and Capstone Projects

Traumatic brain injury (TBI) symptom prevention and remediation is an important area of research that would benefit vulnerable groups, including active-duty and veteran soldiers. These patients can sustain penetrative forces in fields of combat or in training, which result in focal lesions that trigger inflammatory and degenerative processes in the brain. Both primary and secondary injuries are associated with changes to cognition, behavior and affective state. This disease poses increased risk of epileptogenesis, as well. Given these outcomes, prior research has evaluated levetiracetam (LEV) as a prophylactic treatment for seizures, cognitive deficits and negative emotionality. LEV acts as a presynaptic …


Investigating Individual And Group Level Mediators Of Fear Acquisition, Rachel S. Lese Jun 2026

Investigating Individual And Group Level Mediators Of Fear Acquisition, Rachel S. Lese

Dissertations, Theses, and Capstone Projects

The ability to discriminate between cues predictive of threat vs. safety (fear acquisition) and subsequently update fear responding when contingencies change (fear extinction) is crucial to survival for all organisms. While these processes have been the subject of intense experimental scrutiny for several decades, most human fear learning studies have focused primarily on extinction learning and fear recovery processes, with less focus on fear acquisition itself. Indeed, researchers typically aim to minimize variability during fear acquisition in order to rule out differences in extinction being driven by variability during the initial learning phase. Thus, experimental protocols are often optimized to …

Approach–Avoidance Motivation And Goal Adaptation In Chronic Pain: Predicting Pain Intensity And Interference, Paria Eshraghi, Deirdre Drake, Joanne Iddon, Joanne M. Dickson

Research outputs 2022 to 2026

Chronic pain is a major public health concern associated with disability, reduced functioning and psychological distress. Compared with biological studies, relatively little research has studied chronic pain from a psychological perspective, specifically motivation. Yet, motivation is considered fundamental to human functioning and drives human behaviour. The present study aimed to investigate whether distinct motivational and adaptive goal processes are implicated in chronic pain. The sample comprised 190 adult community participants who reported chronic pain for 3 months or more. Participants completed self-report measures of approach and avoidance motivation, adaptive goal processes, pain intensity, and interference. As hypothesised, avoidance motivation (but …
