Examining Mental Health In Mass Shooters, Christina K. Robison, Brooke Mann

SACAD: Scholarly Activities

Mass shootings are defined as shootings that cause 4 or more deaths not including the shooter (excluding those committed in connection to underlying criminal activity, such as gangs or drugs); examples include workplace shootings, school shootings, public shootings, shootings at places of worship, etc. There have been 195 mass shootings since 1966, with 1,398 reported deaths. While several factors influence mass shootings, research points to psychological, sociological, and economic influences. This analysis is over 3 separate studies, having between 172-177 shooters each with the same basic demographics, but separate focuses. Overall, the main focus is looking for patterns that could …

Food For Thought: The Impact Of The Gut-Brain Axis On Mental Health, Emily S. Miiller

Honors Thesis

Research regarding the role of the human microbiome has grown over the years as professionals develop a better understanding of the gut-brain axis. New studies and expanding knowledge on the relationship between the nervous system and gut microbiome promote a deeper understanding of the impact of diet on mental health. Diet plays a crucial role in maintaining a healthy balance between the gut and the brain. Incorporating nutritional modulators, such as probiotics, prebiotics, and vitamins, is crucial for supporting the gut-brain axis by influencing neurotransmitter production, managing inflammation, and promoting the growth of beneficial gut bacteria. On the other hand, …

Let's Grow: Investigating The Relationship Between Houseplants And Mental Health In College Students, Makia G. Adler

Honors Thesis

This literature review explores the potential mental health benefits of houseplants for college students, a population increasingly affected by anxiety and depression. With traditional mental health services strained and often inaccessible, simple and low-cost alternatives are urgently needed. This review examines whether the presence and interaction with houseplants can improve psychological well-being, specifically symptoms of anxiety and depression. Drawing from ten peer-reviewed studies, this review finds a generally positive association between houseplants and mental health, though results vary. Notably, the duration of exposure appears to have little effect, while setting and autonomy in plant interaction are more influential. Interactions in …

Using Musical Interventions As A Non-Pharmacological Strategy To Improve Chronic Pain Levels And Satisfaction Among Patients With Sickle Cell Disease, Fredeline Metellus

Doctor of Nursing Practice Final Project Abstract

Background

Sickle Cell Disease (SCD) is a chronic, inherited blood disorder characterized by severe pain episodes that are often poorly managed with standard pharmacological treatments. In response to patient dissatisfaction with pain control and the desire for holistic alternatives, this quality improvement project explored music therapy as a non-pharmacological pain management strategy.

Purpose

The primary aim was to reduce chronic pain by at least 20% and improve patient satisfaction with pain management among adults with SCD using a structured musical intervention.

This project was implemented at a comprehensive outpatient SCD clinic using the Plan-Do-Study-Act (PDSA) model. Five adult patients …

Investigating Child-Informed Considerations For Animated Picture Symbols Representing Emotion For Aac Use In Children With Asd, Hannah Kitsmiller

College of Education and Human Sciences: Dissertations, Theses, and Student Research

Development of emotional competence is an important area of consideration when supporting individuals who use augmentative and alternative communication (AAC). Emotional competence includes skills related to identifying and communicating about one’s emotions. Individuals who use AAC may struggle to develop strong skills in emotional competence. One potential barrier to developing emotional competence may be access to symbols that facilitate understanding of the represented emotion. Emotions are abstract and challenging to represent in visual symbols. Additionally, evidence suggests individuals with autism spectrum disorder (ASD) may have visual perceptual differences when viewing faces. Current emotion symbols are often depicted using isolated facial …

Transgender And Gender Diverse Young Adults’ Navigation Of Sexuality: What Mental Health Providers Need To Know, Sage A. Volk

Dissertations and Doctoral Documents, University of Nebraska-Lincoln, 2023–

Though literature has documented that TGD individuals may face unique challenges when attempting to develop healthy romantic and sexual relationships (Hill-Meyer & Scarborough, 2014), research has also identified that intimate partners can serve as an immeasurable source of support and resilience for their TGD partners (Coppola et al., 2021; Galupo et al., 2019). While there is strong evidence to support the importance of TGD individuals developing healthy intimate relationships, there is little guidance in the literature for mental health providers wanting to discuss these domains with TGD clients in psychotherapy (Spencer and Vencill, 2017).

The present study addresses this gap …

Transgender And Gender Diverse Youth Navigating Relationships And Sexuality: Recommendations For Affirming Clinical Practice, Hannah Marie Coffey

Dissertations and Doctoral Documents, University of Nebraska-Lincoln, 2023–

Healthy relationship development is critical for adolescents’ social-emotional wellbeing, and shifting social expectations and identity development in adolescence can be challenging (Kenny et al., 2013; Roach, 2018). This can be particularly complex for transgender and gender diverse (TGD) youth given the occurrence of identity development alongside navigating safety, access to affirming spaces, and limited availability of queer-inclusive education (Levitt and Ippolito, 2014; Xing et al., 2015). The positive psychosocial impacts of comprehensive sex education and the relevance of discussing relationships in therapy with adolescents situate mental health providers well to address some of the gaps in knowledge and access to …

From Victimization To Offense: A Scoping Review Of Attachment Theory And Social Learning Theory In Explaining Hypersexual Behaviors In Male Sexual Offenders With Histories Of Childhood Sexual Abuse, Madison R. Rivers

Senior Theses

The association between childhood sexual abuse (CSA) and hypersexual behaviors in both juvenile and adult male sexual offenders has been investigated; however, a clear theoretical framework explaining this connection remains debated. This review aims to evaluate which theoretical frameworks—such as Social Learning Theory and Attachment Theory—best explain the link between CSA and hypersexuality in male sexual offenders. A systematic search and analysis of existing literature was conducted, including studies on the psychological, behavioral, and developmental impacts of CSA on hypersexual behaviors. Both Social Learning Theory and Attachment Theory were critically assessed, particularly focusing on the pathways from victimization to offending …

Methods Comparison For Collecting Subjective Valence And Arousal Judgements, Esha Gandhi

Senior Theses

Human emotion and affect are critical for regulating behavior, guiding decision-making and facilitating social communications. In everyday language, emotion and affect are interchangeable. However, in psychology, they are conceptualized as two distinct constructs. Emotion refers to discrete, prototypical subjective experiences elicited by specific stimuli. Affect, in contrast, refers to more elementary feelings that can be described along two continuous dimensions: valence (positive-negative) and arousal (low-high). According to the circumplex model (Russell, 1980), emotion can be represented within a two-dimensional core affective space defined by valence and arousal. Although valence and arousal are conceptually interrelated, most studies measure them separately using …

Investigation Of Coordinated Visual Attention Using Head-Mounted Eye Tracking In Infants With An Elevated Risk For Autism Spectrum Disorder, Edith L. Violi

Senior Theses

Autism spectrum disorder (ASD) is a prevalent condition characterized by persistent deficits in social communication and restricted, repetitive behaviors. Coordinated visual attention (CVA), the ability to share attention with others through gaze coordination, is a key component of early social development, and differences in CVA may serve as a potential early marker of ASD. Given the increased likelihood of ASD among siblings of diagnosed individuals, research has focused on studying CVA differences to improve early detection and intervention strategies. The thesis aims to examine group differences between elevated likelihood (EL) and low likelihood (LL) infant-parent dyads in toy-directed attention and …

Beyond The Cell: The Impact Of Parental Incarceration On Children Based On The Factors Of Age, Gender, And Race, Ella M. Zeigler

Senior Theses

Incarceration is a life-changing event. It is humbling to be surrounded by three cement walls and a row of metal bars reaching from the floor to the ceiling. Millions of individuals are impacted by the adverse effects of incarceration, but millions more feel the effect of their incarceration as well. There are obvious negative impacts on those who have personally experienced incarceration, but one of the largest impacts is widely overlooked; one that comes from beyond the cell. This thesis considers the variation in the impact of parental incarceration on children, specifically based on the factors of age, gender and …

Expanding The Framework Of Childhood Adversity: Structural Violence And Aggression In Childhood, L. Petrovic, C.N. Baker, Samantha Francois, M. Wallace, S. Overstreet

Psychology

Background: Structural violence harms youth by preventing them from meeting basic needs for safety, belonging, dignity, and agency, leading to negative outcomes like increased aggression. Such behaviors harm children's social and emotional well-being and academic success, particularly affecting Black youth who disproportionately experience structural violence. Although predictors of student aggression have been explored, the specific influence of structural violence—as measured through socioeconomic and racial disparities—remains under examined in the literature. This gap highlights the need for further investigation into how these external factors contribute to aggressive behaviors in school settings, Objective: This study sought to examine the relationship between structural …

Examining The Features Of Former Research Regarding Substance Abuse Treatment, Autumn Gonzales

Posters - 2025

“Drug misuse is one of the major social, legal, and publichealth challenges in the modern world” (Nutt et al., 2007). This study explored the characteristics of former research on substance abuse treatment approaches and treatment settings. Past literature showed short-term treatment can be beneficial depending on what works best for the individual and studies have shown short-term treatment has helped individuals with Substance Use Disorder (SUD). However, long-term treatment is the preferred method for individuals as it has a lower chance of relapse. A small systematic review was conducted from which data were coded of former published articles. A frequency …

The Role Of Asd On The Reality Television Dating Show, "Love On The Spectrum", Priscilla Muñoz

Posters - 2025

• Autism Spectrum Disorder (ASD), a neurodevelopmental disorder that is determined by early challenges in social and communicative behaviors (Taddei et al., 2024), has been studied widely in all stages of life, from toddlers to the elderly (Heijnen-Kohl et al, 2017; Debodinance et al., 2017). • Every case of ASD is unique in that each can present different behaviors, however, there are three behaviors that are prevalent in many cases of ASD. The behaviors that are found and studied often include repetitive behavior (Martinez-Gonzalez, 2022), emotional meltdowns (Lewis & Stevens, 2023), and restricted interests (Jasim & Perry, 2023).

The Silent Pandemic: Link Between Depression, Marijuana Usage And Mental Health Services After The Covid-19 Pandemic, Elias Ciudad, Lori Boies

Posters - 2025

The National Surveys on Drug Use and Health (NSDUH) measure substance use, mental illness, and treatment in the civilian noninstitutionalized population 12 or older. Depression is a public health epidemic that disproportionately affects young adult populations aged 18-25. At the same time, the consumption of marihuana is on the rise and more popular in this demographic group.

This statistical study aims to identify and model predictors of major depressive disorders (MDE) and marijuana abuse among populations older than 18 via standard tests, modeling, odds ratios, and epidemiological approaches for 2023 NSDUH data.

A Research Proposal: Morality As A Social Construct, Samantha Gonzales

Posters - 2025

Separating our minds from the constraints of our social constructs allows us to analyze problems from a place somewhere remotely close to unbiased. However, it is only after we understand that our sense of morale [i.e. right and wrong] originated as social constructs—that is to say, right and wrong have no reason to exist in an objective world. The very concept of right and wrong have been socially constructed from the beginning; they are, in their most simplistic nature, entirely subjective. Subjective in this sense means outside of the very people who speak of the words right and wrong in …

Discrimination At Work: Recognizing And Addressing Systemic Bias, Briana Heggy

Posters - 2025

Race-based workforce discrimination remains a significant issue in the U.S., particularly affecting African Americans, Latinos, and other minority groups. In 2021, the EEOC received over 60,000 workplace discrimination charges, with race discrimination being the most common complaint. Discrimination levels vary by state, influenced by factors like education, minority population size, and political affiliation. Higher education levels can increase awareness of discrimination laws, but also affect job opportunities and earnings. States with larger minority populations may experience different forms of racial discrimination, while political party influence can impact the enforcement of anti-discrimination laws. This research examines how these factors interact to …

Understanding The Experiences Of Nonprofit Leaders In Psychotherapy, Anna Bramlett

Dissertations (1934 -)

Nonprofit leaders are at the helm of organizations that contribute significantly and meaningfully to society. Nonprofit organizations provide a range of services across sectors that include healthcare, education, mental health, civic engagement, and many others. Existing literature attends to the challenges nonprofit leaders face in their work roles, with managing boards and fundraising frequently cited as stressors. Little is known about the mental health experiences of nonprofit leaders, including common mental health diagnoses they experience, prevalence of mental health symptoms, or effective interventions for mental health concerns. The present study sought to explore the experiences of nonprofit leaders who attend …

Perceptions Of Reactions To Trauma Disclosure And Posttraumatic Growth, William David Ewing

Dissertations (1934 -)

This dissertation explores the associations between trauma disclosure likelihood, perceptions of positive and negative social reactions to trauma disclosure, trauma impact, trauma type, and posttraumatic growth (PTG). The study aimed to clarify the ability of these variables to predict PTG, with a particular focus on the mediating roles of positive and negative social reactions to trauma disclosure in the relationship between trauma disclosure likelihood and PTG. Using a cross-sectional design, data were gathered from 184 participants recruited primarily through an undergraduate participant pool, as well as through various trauma-related organizations and online forums. The findings suggest survivors of Type 2 …

A Factor Analytic Investigation Of The Millon Adolescent Clinical Inventory - Second Edition In Justice Involved Youth, Mary Alicia Tait

Dissertations (1934 -)

The Millon Adolescent Clinical Inventory – Second Edition (MACI-II; Millon et al., 2020) is an adolescent self-report measure of personality and psychopathology. Its predecessor, the Millon Adolescent Clinical Inventory (MACI; Millon et al., 1993) is one of the most frequently used measures in forensic evaluation of justice involved youth (Archer et al., 2006; Baum et al., 2009; Viljoen et al., 2010). The factor structure of the MACI has been evaluated in diverse psychiatric and juvenile justice samples (e.g., Adkisson et al., 2002; Newman et al., 2015; Romm et al., 1999, Salekin, 2002; Woodland et al., 2014) and inconsistent findings have …

Distinct Neuropsychological Profiles Of Acute Pediatric Traumatic Brain Injury, Mary Ursula Simons

Dissertations (1934 -)

Traumatic brain injury (TBI) can cause significant impairment in a child’s life, particularly impacting their cognitive and psychological functioning. Despite these significant consequences, there are currently no validated treatments to alleviate or mitigate the negative impact of TBI. Failed clinical trials in pediatric TBI are thought to be due to simplistic diagnostic criteria and coarse classification nomenclature (i.e., mild, moderate, severe), which results in significant variability in recovery within a classification category. Furthermore, other variables, such as age, preinjury functioning, social determinants of health (SDOH), and post-injury cognitive functioning, more effectively predict long term outcomes than classification nomenclature, highlighting the …

The Masculine Way, Jessica Asuquo

be Still

This painting was conceptualized after a particularly impactful patient visit. During the visit, the patient described a traumatic event in greater detail, stating that the doctor and I were the first people he had ever spoken to about the event.

I felt both honored and disheartened by this statement. I was honored that this man trusted us with this knowledge. Still, I was immensely sad that he dealt with the trauma of this event alone for decades. I believe he released some of the grief, pain, anger, fear, and hurt when he shared his burden with us, and I will …

Gender Differences In Perceived Organizational Support Among Veterans With Posttraumatic Stress Disorder, Elizabeth Gomez

Dissertations

Posttraumatic stress disorder (PTSD) is a well-studied issue within the U.S. military, with data showing military personnel face a higher risk of trauma than the civilian population. Many veterans and service members suffer from PTSD related to their military experiences (Renshaw, 2011). As research has largely focused on protective factors such as social and familial support, little attention has been given to organizational support (Meredith et al., 2011). Perceived organizational support (POS) refers to how individuals perceive the support they receive from their employers, with the military as the primary employer for veterans. This study was designed to explore whether …

Social Support As A Buffer Of The Association Between Intimate Partner Violence And Anxiety Among Sexual And Gender Minorities Assigned Female At Birth, Shariell T. Crosby

Theses and Dissertations from DePaul University

Sexual and gender minority (SGM) individuals experience similar to higher rates of intimate partner violence (IPV) compared to the general population (Basile et al., 2020; Whitfield et al., 2021). Additionally, exposure to IPV has been linked to negative mental health outcomes including anxiety (Charak et al., 2019; Henry et al., 2021; Reuter et al., 2017; Strauss et al., 2020). One possible factor that may buffer against the negative effects of IPV on anxiety is social support. The theoretical model of the buffering effect of social support suggests that social support may “buffer” against the harmful mental health effects of stressful/traumatic …

The Effects Of Internalizing Symptoms And Attentional Difficulties On Adolescent Outcomes Of The Peers Intervention, Madeleine Kathleen Guell

Master's Theses (2009 -)

The Program for the Education and Enrichment of Relational Skills (PEERS) is effective at improving the social skills of autistic youth. However, few studies have examined the suitability of PEERS for youth with comorbid mental health concerns. Research suggests that autistic youth are highly likely to have co-occurring disorders such as internalizing and attentional disorders, which are linked with poorer social skills in autistic youth. The current study explores the effects of internalizing symptoms and attentional difficulties on outcomes of the PEERS intervention by examining the relationship between these symptoms and 3 composite outcome variables (i.e., social awareness, social interaction, …

Traditional Gender Roles And Intimate Partner Violence: Exploring Relationships Between Religion, Self-Control, And Alcohol, Carina J. Pawlak

Posters - 2025

IPV is the physical, psychological, or sexual aggression by a married, unmarried, or live-in partner (Patra et al., 2018).

- Male perpetrators are reported for 92% of the IPV cases compared to females and are more likely to severely injure or kill their partners (Levitt et al., 2008).

- In a traditional community that had lax attitudes toward IPV, there was an 80% increase in the likelihood of perpetration and women’s consent to the violence increased their likelihood of victimization by 11% (Linos et al., 2013).

- To maintain traditional gender roles found within religious communities, some men may use …
