A Mixed-Methods Study Exploring Free Nicotine Replacement Therapy As A Strategy To Promote Tobacco Treatment Equity At Cancer Center Cessation Initiative Sites, Marguerite A. Webster
A Mixed-Methods Study Exploring Free Nicotine Replacement Therapy As A Strategy To Promote Tobacco Treatment Equity At Cancer Center Cessation Initiative Sites, Marguerite A. Webster
Theses and Dissertations--Psychology
Nicotine replacement therapy (NRT) is a safe, efficacious smoking cessation treatment for cancer patients; however, equitable access is limited due to insurance gaps. Offering free NRT to patients with cancer has potential to increase tobacco treatment engagement and promote equity. This mixed-methods study aims to describe how some Cancer Center Cessation Initiative (C3I) sites implemented free NRT within their tobacco treatment programs (TTPs) to inform future development of equitable TTPs. Participating sites’ (N=9) TTP and patient population characteristics were assessed via survey and analyzed with descriptive statistics. Semi-structured interviews were conducted with 16 individuals and analyzed using directed …
Fluctuations In Alcohol Impairment Of Working Memory Across The Menstrual Cycle, William Mcgarrigle
Fluctuations In Alcohol Impairment Of Working Memory Across The Menstrual Cycle, William Mcgarrigle
Theses and Dissertations--Psychology
Behavioral endocrinology studies in women suggest that higher circulating levels of the ovarian sex hormone estradiol (E2) may be linked to better working memory performance, especially under conditions of cognitive impairment (e.g., age-related cognitive decline). Phases of the menstrual cycle characterized by different levels of E2 may therefore influence the degree to which women are vulnerable to alcohol impairment of working memory. The current thesis used a within-subjects design to test the hypothesis that women are less sensitive to acute alcohol-induced impairment of working memory when E2 is elevated during the menstrual cycle. A sample of 75 premenopausal women completed …
Disinhibition And Bac Estimation As Predictors Of Risky Driving Behavior While Intoxicated, Sarah Heymsfeld
Disinhibition And Bac Estimation As Predictors Of Risky Driving Behavior While Intoxicated, Sarah Heymsfeld
Theses and Dissertations--Psychology
Alcohol-related driving fatalities persist as a public health problem in the United States. Recent studies have begun focusing on driver risk-taking as a factor in DUI occurrences and consequent driving fatalities. Key factors that could contribute to risky intoxicated driving are a lack of self-awareness concerning intoxication levels and consequent risk in addition to alcohol-induced increases in the driver’s impulsivity. Fifty young adult drivers received 0.65 g/kg of alcohol (target BAC = 80 mg/dl) or a placebo in a counterbalanced order on two different days and performed a simulated driving test that measured driver risk-taking as reduced distance to other …
Power Of Perception: The Role Of Perceived Caregiver Mindset Beliefs On Undergraduate Student Academic Engagement, Katherine R. Tanaka
Power Of Perception: The Role Of Perceived Caregiver Mindset Beliefs On Undergraduate Student Academic Engagement, Katherine R. Tanaka
Theses and Dissertations--Psychology
Promoting academic engagement is vital for college student success. Researchers have explored factors like growth mindset, the belief that intelligence can improve with effort, as a driver of academic engagement. Beyond personal mindset, students’ perceptions of key social influences, such as caregivers, also play a role. This study examined how undergraduate students’ own mindsets and perceptions of their caregivers’ mindsets relate to four components of academic engagement: behavioral and emotional engagement, and behavioral and emotional disaffection. Data from undergraduates (N = 1417) were analyzed using surveys, descriptive statistics, hierarchical regression, and exploratory moderation. Students generally reported both a personal …
Cognitive-Behavioral Effects And Sex Differences In Alcohol Use, Mia Radevski
Cognitive-Behavioral Effects And Sex Differences In Alcohol Use, Mia Radevski
Theses and Dissertations--Psychology
Addiction models (e.g., iRISA model) suggest that excessive substance use can result in behavioral consequences such as decreased response inhibition and increased salience attribution toward alcohol cues. The primary goal of this project was to explore potential sex differences in these characteristics of addiction. This dissertation is comprised of two separate but related studies. Study 1 investigated sex differences in inhibitory control and attentional bias. The central hypotheses are 1) women who reported heavy-drinking would display greater disruptions in behavioral inhibitory control following alcohol-related cues, 2) men who reported heavy-drinking would display greater attentional bias toward alcohol-related cues, and 3) …
Establishing The Feasibility Of Crowdsourcing To Study Value-Based Decision-Making In Substance Use Disorders, Thomas Shellenberg
Establishing The Feasibility Of Crowdsourcing To Study Value-Based Decision-Making In Substance Use Disorders, Thomas Shellenberg
Theses and Dissertations--Psychology
Substance use disorders (SUDs) are characterized by repeated choices to use drugs despite adverse consequences. Value-based decision-making theory posits that choices are guided by predicted values of available options which are updated based on outcomes. Computational modeling of reinforcement learning (RL) during choice tasks has shown promise for uncovering latent mechanisms of decision-making. Recruiting people with SUD is difficult, but crowdsourcing offers an alternative for accelerating data collection. However, the validity of computational modeling using online choice task data has not been well-established. This thesis aimed to use the online crowdsourcing platform Prolific to 1) compare online and in-person choice …
Menstrual Cycle Phase And Hormonal Effects On Emotional Eating In Females With Attention-Deficit/Hyperactivity Disorder, Urveesha Nirjar
Menstrual Cycle Phase And Hormonal Effects On Emotional Eating In Females With Attention-Deficit/Hyperactivity Disorder, Urveesha Nirjar
Theses and Dissertations--Psychology
Previous research has shown that cyclical fluctuations in ovarian hormones can predict changes in ADHD symptoms as well as eating behaviors, particularly emotional eating across the menstrual cycle. Previous studies have so far only examined the effects of estrogen (E2), progesterone (P4) and cycle phase in predicting individual symptoms or disorders such as ADHD or eating disorders or related behaviors separately. The aim of this study is to examine how emotional eating is influenced by naturally occurring hormonal and cycle changes in a sample overrecruited for ADHD. Seventy-eight individuals (assigned female at birth) with menstrual cycles overrecruited for ADHD provided …
Intimate Partner Violence And Parent Perceptions Of Their Emotional Bond To Their Children, Lia T. Mclanahan
Intimate Partner Violence And Parent Perceptions Of Their Emotional Bond To Their Children, Lia T. Mclanahan
Doctor of Psychology (PsyD)
As research on intimate partner violence (IPV) continues to grow and there are more ways of defining IPV and identifying its differing forms, a related topic of interest has become the impact IPV has on families (Fong et al., 2019). Similarly, research on IPV as a form of trauma and its implications is well-researched for both children and adults, as is the research on trauma and attachment (Cook et al., 2017). However, there seems to be a lack of research on how parent–child attachment is predicted by IPV. The present study aimed to assess how parent perceptions of their level …
Weathering The Storm: Risk And Resiliency Factors In Transgender And Gender-Diverse Youth, Haley R. Hedrick
Weathering The Storm: Risk And Resiliency Factors In Transgender And Gender-Diverse Youth, Haley R. Hedrick
Doctor of Psychology (PsyD)
Compared with their cisgender peers, transgender and gender-diverse (TGD) youth face unique and significant risk factors and are at increased risk for health disparities due to intersectional psychosocial factors including high prevalence of childhood trauma, discrimination and minority stress, societal stigma, and lack of access to competent, comprehensive, gender-affirming healthcare. A total of 180 participants were included in the current study, comprised of a clinically-derived sample of TGD youth aged 8–20 years (M = 14.42, SD = 2.17), and their parents. The current study examined risk and resilience variables relevant to TGD youth, with specific focus on adverse childhood events, …
Fatigue Reporting In Hellenic Skies: Attitudes, Barriers And Insights From Military, Commercial And General Aviation Pilots, Panagiotis Kioulepoglou, Katerina M. David, Vassilios Nikolaidis, Ilias Makris
Fatigue Reporting In Hellenic Skies: Attitudes, Barriers And Insights From Military, Commercial And General Aviation Pilots, Panagiotis Kioulepoglou, Katerina M. David, Vassilios Nikolaidis, Ilias Makris
International Journal of Aviation, Aeronautics, and Aerospace
Fatigue has long been a concern in aviation, especially today, with the ever-increasing traffic volume, pilot shortage, and operations that often disrupt the body’s natural biological rhythms. Despite the implementation of sophisticated fatigue reporting schemes, aviation organizations still face challenges, as many studies indicate that pilots often encounter barriers to effectively report their fatigue. As relevant research in Greece was scarce, the main objective of this study was to explore Greek pilots' attitudes towards fatigue reporting, identify the most significant barriers, and recommend mitigation measures based on the participants' perspectives. To that end, 18 semi-structured interviews were conducted and analyzed …
Pain Anxiety And Pain Interference As Mediating Factors In The Relation Of Childhood Trauma And Fear Of Cancer Recurrence, Jennifer Kuo
Pain Anxiety And Pain Interference As Mediating Factors In The Relation Of Childhood Trauma And Fear Of Cancer Recurrence, Jennifer Kuo
Dissertations and Theses
Fear of cancer recurrence (FCR), which is broadly defined as “the fear that cancer could return or progress in the same place or in another part of the body” (Vickberg, 2003), is often identified as an unmet need among cancer survivors, with rates ranging from 20-79% (Simard et al., 2013). Pain, another symptom commonly endorsed in cancer survivorship, is positively associated with fear of cancer recurrence (Janz et al., 2011; van den Beuken-van Everdingen et al., 2008). The Cancer Threat Interpretation Model suggests that cognitive biases exist in interpreting threat appraisal and pain coping by increasing the saliency of pain …
Online Perceived Social Support And Its Association With Psychopathology In Rural And Urban Youth, Ellen Alexandra Knowles
Online Perceived Social Support And Its Association With Psychopathology In Rural And Urban Youth, Ellen Alexandra Knowles
Dissertations and Theses
Social support is a fundamental aspect of development throughout adolescence. It has been found to buffer against the negative impacts of stress and provide general benefits to one’s well-being. Youth today are exposed to a range of opportunities for socialization with peers, both in-person and online, including interacting with others through texting, social media, video games, and other digital means. These online interactions have begun to be investigated as accessible methods through which adolescents can connect with others and maintain healthy relationships. Furthermore, digital social networks may be most critical for youth from isolated communities, including those from rural areas. …
Childhood Maltreatment And Posttraumatic Stress Symptom Clusters: The Mediating Role Of Early Maladaptive Schemas, Sydney Nichole Stamatovich
Childhood Maltreatment And Posttraumatic Stress Symptom Clusters: The Mediating Role Of Early Maladaptive Schemas, Sydney Nichole Stamatovich
Dissertations and Theses
The current study tested a structural equation model to examine the associations between types of childhood maltreatment (i.e., neglect, punishment, and sexual abuse), Jeffrey Young’s early maladaptive schemas (EMSs), and posttraumatic stress disorder (PTSD) symptom clusters (i.e., avoidance, hyperarousal, intrusion, and negative alterations in cognitions and mood) in a sample of college students. Childhood maltreatment is a pervasive problem in the United States of America and has several short- and long-term physical and psychological consequences. Of note, victims of childhood maltreatment are at an elevated risk of developing PTSD. Further, childhood maltreatment and PTSD are associated with negative alterations in …
Crisis Intervention Model Effectiveness In South Dakota City And Rural Schools, Nicole Ann Bechen
Crisis Intervention Model Effectiveness In South Dakota City And Rural Schools, Nicole Ann Bechen
Dissertations and Theses
Little information is known on crisis prevention and intervention plans in schools across South Dakota. A review of the existent literature revealed gaps within school-based crisis intervention models, their objectives, and their effectiveness in addressing the psychological and physical safety needs of students, staff, teachers, families, and community members. Gaps in understanding rural crisis response were noted. The purpose of this study was to assess whether crisis prevention and intervention plans in South Dakota schools adequately protected students, staff, families, and community members. To achieve this, a stratified random sample of 53 PreK-12 public schools in the state of South …
Music And Perceived Stress: An Investigation Into The Effects Of Music On Chemistry Students' Perceived Stress Levels, Alice Young, Eric Malina
Music And Perceived Stress: An Investigation Into The Effects Of Music On Chemistry Students' Perceived Stress Levels, Alice Young, Eric Malina
Honors Program: Senior Projects (Public)
Music has long been a prevalent intervention when trying to lower stress in certain populations (Thoma et al., 2013). This study aimed to explore the possible usefulness of music as an intervention for students experiencing stress in the chemistry laboratory setting. Students in general chemistry laboratories were surveyed regarding their stress at the ends of periods in which music was or was not played in their laboratory classes. While the results were not statistically significant, mean stress scores did lower in those groups where music was played. Further research into this topic should focus on type of music, the effects …

Teen-to-teen (t2t) crisis lines are a special type of crisis service where youth volunteers help their peers. Although prior research has examined the experience of adult crisis line responders, no research has examined the experience of adolescents who do this work. In collaboration with two of the largest t2t lines in the U.S., this pilot study is the first examination of t2t crisis line work. Volunteers (ages 14–20) reported: their primary motivation for joining the crisis lines was to help others and give back to the community; responding to a range of peers’ problems on the t2t crisis line, …

The potential and threat of digital tools to achieve health equity has been highlighted for over a decade, but the success of achieving equitable access to health technologies remains challenging. Our paper addresses renewed concerns regarding equity in digital health access that were deepened during the COVID-19 pandemic. Our viewpoint is that (1) digital health tools have the potential to improve health equity if equitable access is achieved, and (2) improving access and equity in digital health can be strengthened by considering behavioral science-based strategies embedded in all phases of tool development. Using behavioral, equity, and access frameworks allowed for …
A Meta-Analysis Of Attachment At Work, Kate N. Warnock, Christina S. Ju, Ian M. Katz
A Meta-Analysis Of Attachment At Work, Kate N. Warnock, Christina S. Ju, Ian M. Katz
Psychology Faculty Publications
This meta-analysis aimed to confirm and clarify the relationships between attachment style and various workplace correlates, including job performance, burnout, personality, and job satisfaction (K = 109 independent samples, N = 32,278 participants). Results provided the strongest support for the relationships between attachment style and the Big Five personality traits, burnout, and job performance. Anxious attachment was also related to a host of other correlates, including job stress, turnover intentions, job satisfaction, and work engagement. Additionally, dominance analysis was used and found that attachment style had incremental validity beyond the Big Five in the prediction of job performance, job satisfaction, …
Neuroticism Mediates The Association Between Autistic Traits And Choice Reaction Time Among Young Adults, Kassandra De Jesus Cintron, Xiao Yang
Neuroticism Mediates The Association Between Autistic Traits And Choice Reaction Time Among Young Adults, Kassandra De Jesus Cintron, Xiao Yang
Psychology Faculty Publications
Autism spectrum disorder (ASD) is a neurodevelopmental disorder that influences an individual’s cognitive functions and social interaction. While most studies have focused on children and adolescents diagnosed with ASD, elevated levels of autistic traits in subclinical populations may also influence individuals’ daily functioning. Autistic traits are also linked to the Big Five personality. In particular, neuroticism (emotion instability) has been shown to be positively associated with autistic traits, which may contribute to behavioral symptoms of autistic traits. The present study aimed to investigate the association between autistic symptoms and sensorimotor processing among a subclinical population. One hundred young adults (M …
Evaluation Of Resurgence Following Differential Reinforcement Of Alternative Behavior With And Without Extinction In A Human-Operant Model, Skylar Dewitt
Master's Theses and Doctoral Dissertations
Differential reinforcement of alternative behavior (DRA) plus extinction for problem behavior is an evidence-based intervention for individuals diagnosed with autism. However, researchers have recently begun investigating DRA without extinction, given this treatment component may be unsafe or impractical to implement in practice. Although preliminary research has indicated DRA without extinction as an effective intervention alternative, little is known about the long-term implications of this intervention, especially as it relates to resurgence. This study investigated resurgence following DRA with and without extinction using a three-phase resurgence assessment in a human-operant arrangement across 60 college-aged participants. Several study iterations were required to …
Exploring The Effects Of Interviewer Body Language Availability During A Videoconference Behavioral Health Interview, Efthymia Orkopoulou
Exploring The Effects Of Interviewer Body Language Availability During A Videoconference Behavioral Health Interview, Efthymia Orkopoulou
Master's Theses and Doctoral Dissertations
This experiment sought to explore whether an interviewer’s body language availability would have any effects on participants’ interactional engagement levels, positivity-negativity of interaction, and their nonverbal synchrony. Six participants answered questions about their well-being during a Zoom interview. Participants were exposed to three Near and three Far video framing conditions alternating every 10 min. Results showed that body language availability did not have reliable effects on the examined nonverbal communication indices. Time, however, did have some significant and close-to-significant effects on certain variables. Treatment reversal graphs showed that body language availability may reliably impact some participants’ responding. However, the rarity …
Neural Correlates Of Executive Functioning In Preschool Children, Michelle Lobermeier
Neural Correlates Of Executive Functioning In Preschool Children, Michelle Lobermeier
Master's Theses and Doctoral Dissertations
Healthy development of executive functioning (EF) provides an important foundation for emotional and behavioral regulation as well as academic success. Preschool is a time of rapid EF development, making this a target age group for identifying and intervening on EF weaknesses. Since EF has been historically difficult to behaviorally measure in preschoolers, the current study explores neural correlates of EF as another method by which to understand its development. The goal of the present study is to explore associations between resting state electroencephalography (EEG) power (i.e., theta, alpha, beta) and EF ability in preschool and examine how early regulatory ability …
The Biobehavioral Effects Of Embryonic Exposure To Neural Inflammation And Oxidative Stress In Zebrafish, Dalton J. Anderson
The Biobehavioral Effects Of Embryonic Exposure To Neural Inflammation And Oxidative Stress In Zebrafish, Dalton J. Anderson
Honors College Theses
The purpose of this research is to improve understanding of the neurodevelopmental effects of embryonic exposure to elevated inflammation and oxidative stress induced by the antipyretic drug acetaminophen (APAP). Our study was the first to examine the interactive effects of APAP and inflammation in zebrafish embryos and how the treatments affect brain development and larval behavior. Experimental groups of zebrafish larvae were exposed to lipopolysaccharide (LPS) to induce inflammation, APAP, or LPS + APAP and larval behavior was analyzed using Ethovision automated behavioral tracking software. We also measured changes in whole-brain Glycogen Synthase Kinase 3 Beta (GSK3B) and GSK3B phosphorylation, …
Performance Activism Versus Collective Action, Grace Belt
Performance Activism Versus Collective Action, Grace Belt
Cal Poly Humboldt theses and projects
Collective action is how groups can change society. According to the social identity model of collective action (SIMCA), facets of group identification can motivate or discourage collective action. However, no current research has focused on motivations for engagement in performance activism (i.e., displaying support for a mobilized group without engaging in mobilization) from an ingroup perspective. The current study investigates this literature gap, focusing on the dynamics of group membership, specifically feelings of self-prototypicality, as motivation to engage in performance activism or collective action. Participants (N = 189) were made to feel they were core members (prototypical) or fringe …
The Exceptionalist-Normalist Continuum: Contents, Correlates, And Consequences Of Beliefs About The Psychological (A)Typicality Of Perpetrators Of Mass Atrocities, Dylan Campbell
Electronic Theses & Dissertations (2024 - present)
A consensus view within the literature on perpetrator behavior in mass atrocities holds that perpetrators tend to be psychologically typical rather than atypical and thus, that even “ordinary” people are capable of extreme acts of violence against civilians when the right combination of social-psychological forces is at work. Whereas much prior research speaks in some way to this claim’s validity, no prior study of which I am aware has directly investigated laypeople’s beliefs regarding the truth of this proposition. Here, I report findings from four preregistered studies (total N = 1,256) investigating the contents, correlates, and consequences of lay theories …
Unpredictable Positive Experience Response (Uper) Training In Male And Female Rats: Effects On Cognition, Emotional Resilience, And Neuroplasticity Markers, Eve M. Barringer
Unpredictable Positive Experience Response (Uper) Training In Male And Female Rats: Effects On Cognition, Emotional Resilience, And Neuroplasticity Markers, Eve M. Barringer
Honors Theses
This study investigated the effects of positive anticipation on depression-like symptoms in Long Evans male and female rats, using Unpredictable Positive Experience Response (UPER) training. Rats that received UPER training (UPER group) were exposed to cues followed by a positive reward at random times, fostering anticipation of three different positive experiences. Along with the UPER rats, there was a group of rats that received positive rewards without anticipation (ENR group) and a group that received no positive reward or anticipation (CTRL group). After 7 weeks of behavioral… training, we examined how training impacted the animal’s cognition, emotional resilience, and neurobiological …
(Re)Constructing Race: How Essentialist Beliefs Shape Social Justice Support, Abbey Alvarado
(Re)Constructing Race: How Essentialist Beliefs Shape Social Justice Support, Abbey Alvarado
Honors Theses
The political climate and social discourse around social justice has grown increasingly tense and hostile in recent years. The current study investigated potential predictors of the opposition to support for racial equity and social justice reforms. Research illustrates that a biological conceptualization of race (“essentialism”) has powerful implications on information processing and social-psychological outcomes regarding issues of race and racism. In the current study, we conducted a survey of 164 University of Richmond undergraduate students. The survey examined the interplay of essentialism and beliefs about systemic racism and white privilege on social justice support. The results showed that essentialist beliefs …
Black And Blue All Over: Whose Lives Matter?, Bella Purvis
Black And Blue All Over: Whose Lives Matter?, Bella Purvis
Honors Theses
This study investigated the influence of beliefs about race on support for the Black Lives Matter (BLM) and Blue Lives Matter (BluLM) movements, mediated by attitudes towards police and beliefs about white privilege. Utilizing a sample of undergraduate university students, data were obtained through a survey measuring beliefs in the biological and social constructs of race, support for police, belief in white privilege, and attitudes toward BLM and BluLM. Results indicated that individuals who perceive race as a biological construct are less likely to support BLM and more likely to support BluLM, while beliefs in white privilege and attitudes towards …
Longitudinal Associations Between Peer Victimization And School Belonging In Elementary-Aged Children, Bridget E. Mcguiness
Longitudinal Associations Between Peer Victimization And School Belonging In Elementary-Aged Children, Bridget E. Mcguiness
Honors Theses
Belonging is crucial for children’s social adjustment, and peer victimization has the potential to threaten belonging. Alternatively, it is possible that low levels of belonging can elicit higher victimization. My study determined the directionality of the relationship between peer victimization and belonging and whether gender moderated the relationship. There was no evidence that peer victimization was associated with decreases in classroom belonging, but low belonging was associated with higher levels of peer victimization. Gender did not moderate the relationship.
Prototypicality And Need To Belong: How One’S Standing In The Group Affects Parochial Cooperation, Huidi Yuan
Prototypicality And Need To Belong: How One’S Standing In The Group Affects Parochial Cooperation, Huidi Yuan
Honors Theses
This study explores the dynamics of parochial cooperation within intergroup social dilemmas, specifically examining the roles of harm, prototypicality, and the need to belong (NTB). Utilizing an experimental design and an adapted investment game, the study investigates how these factors influence individuals' decisions to engage in cooperation that is biased towards their own group, especially when such actions potentially harm outgroup members. The findings reveal a strong preference for parochial cooperation over universal cooperation and free-riding, consistent with previous research on ingroup favoritism. Notably, this preference is significantly moderated by the harm condition, where participants reduced their parochial investments when …
