You Can Only Take Your Clients As Far As You’Ve Been Yourself: Examining The Intersections Between Psychedelic-Assisted Therapy, Lived-Living Experience, And Clinical Practice, Jordan J. Negrine, Stephen J. Bright, Monica J. Barratt, Matthew Pennell, Anthony Barnett, James Bennett-Levy, Timothy Piatkowski

Research outputs 2022 to 2026

Background: Following Australia’s landmark 2023 decision to approve psilocybin and MDMA for clinical use, psychedelic-assisted therapy (PAT) is beginning to emerge within regulated mental health settings. This study investigates psychologists’ views on the relevance of psychedelic therapists’ lived-living experience (LLE) with psychedelics. While discussion around LLE is growing, little is known about how psychologists perceive its role in clinical preparedness for PAT. Methods: Twenty Australian psychologists were recruited through purposive and snowball sampling. Semi-structured interviews explored perceptions of LLE in therapist training and practice. Data were coded and thematically analyzed to identify patterns in how experiential knowledge is valued within …

Improving Psychiatric Paraprofessional Preparedness Through Mental Health First Aid Training In An Outpatient Mental Health Clinic, Anisha Hampton

DNP Scholarly Projects

BACKGROUND: Paraprofessional staff in outpatient mental health clinics play a critical role in monitoring clients with serious mental illness (SMI) and supporting continuity of care in community-based settings. However, the absence of standardized training contributes to variability in staff knowledge, confidence, and ability to recognize early signs of mental health deterioration. Mental Health First Aid (MHFA) is an evidence-based training designed to improve mental health literacy and crisis response skills among frontline workers.

METHODS: This quality improvement project utilized a pre-post design within a Plan-DoStudy-Act (PDSA) framework at an outpatient mental health clinic. Paraprofessional staff completed the Mental Health Literacy …

Socio-Spatial Patterns Of Suicide Mortality In The United States, Kushagra Tiwari, M. Amin Rahimian, Marie-Laure Charpignon, Philippe J. Giabbanelli, Praveen Kumar

VMASC Publications

Suicides cause more than 49,000 deaths per year in the United States, including 55% associated with the use of a firearm. Across states and counties in the US, suicide mortality exhibits substantial geographical and sociodemographic heterogeneity. However, the role of large-scale social networks in shaping this variation remains underexplored. To assess how both the risk of suicide mortality and the effect of firearm restriction policies propagate through inter-county social ties, we integrate data on county-level suicide mortality (2010–2022) and the Facebook Social Connectedness Index (SCI), a continuous measure of the strength of social ties between counties used to derive weighted …

The Effects Of Stress-Related Hormones On Excitatory Synapse Formation, Autumn C. Garvey

Honors Undergraduate Theses

Stress profoundly influences brain function through neuromodulatory hormones that regulate synaptic plasticity, yet how temporal patterns of hormone exposure shape excitatory synapse formation remains poorly understood. This study investigates how exposure to stress hormones, norepinephrine and cortisol, affects excitatory synapse development. While existing research primarily compares concentration models, real-world stress occurs in variable patterns that may produce distinct neural outcomes. To address this gap, differentiated Neuro2A neuronal cells are exposed to norepinephrine or cortisol under a continuous treatment paradigm designed to model chronic stress conditions. Following treatment, immunofluorescence imaging is utilized to quantify excitatory synapse formation through analysis of presynaptic …

Studying Chronotypes And Their Role In Sleep And Mental Health: A Scoping Review, Evan Nguyen

Honors Undergraduate Theses

Sleep patterns remain a significant public health concern globally, impacting several aspects of life, including mental health. This scoping review examined how chronotype and circadian typology predict mental health, with sleep quality serving as a crucial mediator. While the importance of sleep is widely acknowledged, there is a lack of studies specifically investigating chronotype-aligned interventions to reduce psychological distress. To address the shortage, a comprehensive review of the peer-reviewed literature was conducted, identifying six papers for analysis. These studies mostly utilized cross-sectional designs to assess diverse global groups, including university students, healthcare workers, and military personnel. The results indicate that …

Pillpetz: A Smarter Way To Encourage Medication Adherence In Children, John H. Begley

CMC Senior Theses

Medication adherence is usually framed as a problem of patient behavior, but this thesis argues that it is equally a problem of design. Children who take daily medication face barriers that adults often do not: developing executive function, dependence on caregivers, shifting school and home routines, privacy concerns, and stigma around being perceived as different. The standard prescription bottle, by contrast, was designed primarily for dispensing efficiency, safety, and accidental ingestion prevention—not for sustained daily use by a developing child.

This thesis proposes PillPetz, a smart pill case and digital companion that uses routine, play, dose confirmation, and caregiver-connected support …

Examining The Effects Of Virtual Nature Exposure And Video Immersion On State Hope With Nature Relatedness As A Covariate, Zachary Arneson

All Master's Theses

Previous work in the field of environmental psychology has shown that virtual nature exposure can produce many psychological benefits for the viewer. Within this literature, however, there has been no examination of the effects of virtual nature exposure on levels of state hope, a goal-directed positive psychological construct made up of two types of thought: agency and pathways. Additionally, there has been no direct examination of the effect of immersion level of the virtual nature exposure on psychological measures. To fill this gap in the literature, the current study examined the effects of virtual nature exposure and video immersion on …

Behavioral Science Faculty Publications

Aims: This study characterized the heterogeneity of opioid withdrawal by comparing naturally occurring withdrawal during opioid abstinence (spontaneous withdrawal) with abrupt, pharmacologically induced naloxone-precipitated withdrawal in adults with Opioid Use Disorder (OUD).   Methods: A secondary analysis was conducted on de-identified data from 86 adults meeting DSM-5 criteria for moderate-to-severe OUD. Participants either presented in spontaneous withdrawal (n = 28) or underwent naloxone challenge to precipitate withdrawal (n = 58). Withdrawal symptoms were rated using the Wang procedure. Principal Component Analysis (PCA) of binary symptom data was performed to identify dominant patterns of symptom co-occurrence. Separate PCAs were then …

Cognitive Load Classification Using Functional Near-Infrared Spectroscopy, Pratham Shah

Theses and Dissertations (Comprehensive)

This thesis investigates the classification of cognitive load using functional near-infrared spectroscopy (fNIRS) signals recorded during an N-back working memory task. The study introduces a novel short-channel correction layer designed to suppress superficial physiological noise adaptively, addressing limitations of traditional General Linear Model (GLM) based regression. A single participant dataset comprising 69 validated sessions was analyzed using both conventional machine learning and deep learning approaches. Traditional classifiers: Linear Discriminant Analysis (LDA), Support Vector Machines (SVM), Random Forests, and Gradient Boosting were first evaluated using statistical features (mean, variance, peak, and slope). Among these, Gradient Boosting achieved the highest accuracy (55.6%), …

Havens, Brittney D. Williams, Takako Schaninger, Virginia A. Shepherd-Tackett, Michelle R. Lofwall, Michele Staton, Sharon L. Walsh, Hannah K. Knudsen

Behavioral Science Faculty Publications

Introduction: The advent of curative direct acting antiviral (DAA) drugs to treat those actively infected with the hepatitis C virus (HCV) has allowed for discussion around HCV elimination. Restrictive state-by-state policies for the coverage of DAAs for Medicaid recipients may hamper elimination efforts in the United States by limiting access to these curative treatments. Methods: The purpose of the current analysis was to examine the sociodemographic, drug use and clinical characteristics of participants in the Kentucky Viral Hepatitis C Treatment (KeY Treat) study in the context of Medicaid policies in the United States. The goal of KeY Treat was to …

The Interaction Of Tobacco Retailer Density And Rurality With Tobacco Use Prevalence In Kentucky, Shyanika W. Rose, W. Jay Christian, Judy Van De Venne, Delvon T. Mattingly, Bethany Shorey Fennell, Saber Feizy, Mary Kay Rayens

Behavioral Science Faculty Publications

Purpose: Tobacco retailer density is a key correlate of tobacco use prevalence in the United States, but this relationship has typically been examined in urban areas. We examined the relationship between retailer density and tobacco use across Kentucky counties, a state with high smoking rates and a substantial rural population.

Methods: We obtained a list of tobacco retailers from the 2021 Kentucky Synar program, used for minor’s access inspections. We merged these data with county-level prevalence estimates for cigarette and smokeless tobacco use for each county in Kentucky, calculated using pooled 3-year estimates (2017-2019) of Kentucky Behavioral Risk Factor Surveillance …

Acceptability And Appropriateness Of Harm Reduction Vending Machines Compared To Syringe Service Programs In Appalachian Kentucky, Hannah K. Knudsen, Jennifer R. Havens, April M. Young

Behavioral Science Faculty Publications

Objective:

Many rural people who inject drugs do not use syringe service programs (SSPs). In addition, people who use drugs but do not inject may perceive that SSPs are not intended for their use. Harm reduction vending machines (HRVMs) may be preferred by some individuals. This study examines attitudes and preferences regarding HRVMs to consider possibilities for enhancing the reach of harm reduction services. Method:

Structured surveys were conducted with 712 people who use drugs in two rural Appalachian counties in Kentucky. Participants rated the acceptability/appropriateness of SSPs and HRVMs; HRVM preference was the difference between the two scales. Linear …

Perceived Neighborhood Disadvantage And Current Nicotine Pouch Use Among U.S. Youth, Delvon T. Mattingly, Meman Diaby, Jing Zhang, Juhan Lee, Melinda J. Ickes

Behavioral Science Faculty Publications

Introduction: Nicotine pouches (NPs) are emerging nicotine products that appeal to youth due to their discreet use, tobacco-free formulation, and flavor availability. However, given their recent introduction to the market, little is known about how neighborhood environments may influence US youth NP use.

Methods: We imputed cross-sectional data from the 2023 National Youth Tobacco Survey (n = 22,069, ages 9 + years) and developed a neighborhood risk score (range: 1–4) by averaging 10 items related to neighborhood disorder, safety, and disadvantage. To estimate associations between the risk score and current (past 30-day) NP use, we fit logistic regression models adjusted …

Beyond Weak Ties In Prison: An Investigation Of Core Support Networks Of Incarcerated Persons, Siyun Peng, Martha Tillson, Maria Rockett, Marisa Booty, Carrie B. Oser

Behavioral Science Faculty Publications

Tie formation has been a core interest of network researchers. However, most existing research on tie formation in prisons has focused on weak ties, assuming that a core network approach is less applicable within total institutions such as prisons. Drawing on egocentric network data from 389 incarcerated individuals and 1352 named network members, this study demonstrates that relationships between incarcerated persons can be examined using a core support network framework. We find that about 20 % of participants include at least one incarcerated peer in their core support networks, with these ties providing both practical and emotional support comparable to …
