Grief On The Margins: The Death Of A Family Member To Substance Use, Adair Shaw

Theses and Dissertations (Comprehensive)

Despite Canada's high death rates from substance use, there is limited research on the sociopsychological impact on families, who often face stigma and disenfranchised grief. This study explores how family members make meaning of a substance-related death. Through qualitative inquiry, eleven family members were interviewed on their experience of grief from substance death. The imprint of losing a family member to mental illness and substance use is fraught with intergenerational grief, ambiguity, prolonged mental-emotional distress, and relationship challenges. Substance death was also associated with stigma, social withdrawal, and shame for many participants. However, grievers reconstructed the socially prescribed negative perceptions …

2slgbtq+ Contact As A Vehicle For Promoting Alternative Sexual Scripts Through Exposure To Queer And Trans Ways Of Knowing, Sophie R. Landry

Theses and Dissertations (Comprehensive)

Research on the Traditional Sexual Script (TSS) suggests it can have harmful repercussions, such as sexual violence, gender inequity, and the undermining of communication. My research explores the novel idea that intergroup contact with 2SLGBTQ+ individuals can promote CisHet (cisgender, heterosexual) individuals to value alternative sexual scripts that emphasize communication, authenticity, and equity, and to question the TSS. In Study 1, I found that CisHet people who had more 2SLGBTQ+ contact reported greater concern for consent and were less likely to agree with traditional gender norms relative to those who made less contact. In both Study 2 and Study 3, …

The Effects Of Mindfulness On Chronic Pain In Children And Adolescents: A Systematic Review, Sophie Parks

Electronic Theses & Dissertations (2024 - present)

Mindfulness and mindfulness-based interventions have become increasingly popular in recent years. Typically, mindfulness-based interventions and their effects on mental health and/or adult populations have been explored in the literature. Limited research has been completed looking at mindfulness’ impacts on other facets, including chronic pain symptoms. Additionally, some research has been conducted to analyze mindfulness and its effects on school aged children and their day-to-day functioning with promising results. In this systematic literature review, mindfulness interventions and their effects on children and adolescents who experience chronic pain were explored. The Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) framework was …

Integration Of Theoretical Frameworks For Problematic Exercise: Toward A Comprehensive Model Of Maladaptive And Adaptive Exercise, Christina M. Sanzari

Electronic Theses & Dissertations (2024 - present)

Exercise can promote health and well-being, and yet a proportion of individuals who exercise develop a maladaptive relationship with physical activity. Problematic exercise is often associated with significant impairment and psychological distress, yet a consensus has not been reached regarding how problematic exercise should be conceptualized. The literature distinguishes between primary exercise dependence, or excessive exercise driven by its intrinsic reinforcement, and secondary exercise dependence, or excessive exercise driven by compensatory motivations related to weight and shape concerns. However, to date, little is known about the prevalence and nature of exercise dependence in the absence of eating pathology. This incongruity …

Risk Factors For Executive Functioning Development In Preschool Children With Type 1 Diabetes, Victoria L. Ledsham

Electronic Theses & Dissertations (2024 - present)

Links between Type 1 diabetes (T1D) and decreased cognitive functioning in children are well documented, but research on executive functioning (EF) in this population is more limited. Multiple T1D-related risk factors (e.g., hypoglycemia, hyperglycemia, glycemic variability, diabetic ketoacidosis) for EF have been established throughout the literature, but their individual effects have been difficult to determine given their interrelated nature. In result, cumulative risk has been proposed as a more robust predictor of EF differences in children with T1D. Moreover, despite the importance of early T1D onset as a risk factor for EF impairment, no studies have previously investigated EF in …

Concurrent Parasympathetic Synchrony In Romantic Couples Exposed To Childhood Maltreatment Subtypes, Kate L. Senich

Electronic Theses & Dissertations (2024 - present)

Early responsive caregiving hones children’s physiological systems and subsequently supports social interactions (Feldman, 2007; Porges 2001; Steelman et al, 2002). Conversely, mis-attuned interactions with caregivers, such as exposure to maltreatment subtypes, might hinder social engagement capacities at both behavioral and biological levels (Kim & Cicchetti, 2004; Sheridan & McLaughlin et al., 2014). These early adverse influences endure across development and can affect behavioral and physiological interactions with romantic partners (Mayo et al., 2021; River et al., 2020; Zamir, 2022). Specifically, temporally coordinated patterns of physiological responses between partners (i.e., synchrony) are linked with important relationship behaviors, including conflict behaviors …

Contributions Of Birthing People’S Prenatal Parasympathetic Nervous System Functioning And Postnatal Sensitivity On Infant Temperament, Amanda M. Flagg

Electronic Theses & Dissertations (2024 - present)

Grounded in developmental psychobiology, this research aimed to elucidate how birthing people’s physiological regulation during pregnancy may shape the early emergence of socioemotional development in early infancy. The present study examined how birthing people’s prenatal parasympathetic nervous system (PNS) activity, specifically baseline high-frequency heart rate variability (HF-HRV) and HF-HRV withdrawal, and postnatal sensitivity contributes to infant temperamental reactivity at six months of age. The study aimed to clarify early developmental mechanisms through which birthing people’s PNS shapes emerging infant temperament. Data were drawn from a longitudinal cohort of Black and African American birthing people, a population underrepresented in psychophysiological research, …

Clinical Experiences In Conducting Empirically Supported Treatments For Insomnia, Sondra S. Tiab

Electronic Theses & Dissertations (2024 - present)

Controlled research shows that cognitive-behavioral therapy (CBT) is an effective treatment for insomnia, yet clinician experiences with applying CBT in routine settings has received limited attention. This study replicated and extended upon the Two-Way Bridge initiative (Goldfried et al., 2014), which aimed to establish a dialogue between researchers and clinicians on the identification of variables that promote and interfere with the effectiveness of evidence-based therapies. This survey study asked clinicians to identify variables they have encountered that make it challenging to implement CBT and related interventions for insomnia. N = 182 clinicians completed an online survey on typical assessment practices, …

Postnatal Programming Of Infant Temperament At 12-Months: A Test Of Lactation Programming Theory, Lydia Bierce

Electronic Theses & Dissertations (2024 - present)

The current study examined how maternal cortisol and breastfeeding duration across the first six months postpartum might relate to infant temperament profile membership at 12 months in 322 low-income Mexican American mother-infant dyads (46.3% male). Results revealed that maternal postnatal cortisol levels were significantly moderated by breastfeeding duration to predict infant temperament profile (β = 0.14, p = .030) such that more maternal cortisol was linked to higher likelihood of belonging to a high positive affect, well-regulated profile when mothers breastfed for above average durations. This suggests that while maternal cortisol in breastmilk might initially shape infant negative temperament, …

Data‐Driven Approach To Dynamic Resting State Functional Connectivity In Post‐Traumatic Stress Disorder: An Enigma‐Pgc Ptsd Study, Jacklynn M. Fitzgerald

Psychology Faculty Research and Publications

Using functional magnetic resonance imaging (fMRI), symptoms of posttraumatic stress disorder (PTSD) have been associated with aberrations in brain networks in the absence of a given cognitive demand or task, called resting-state networks. Prior work has focused on disruption in the static functional connectivity (FC) among specific regions constrained by a priori hypotheses. However, dynamic FC, an approach that examines brain network characteristics over time, may provide a more sensitive measure to understand the network properties underlying dysfunction in PTSD. Further, using a data-driven analytic approach may reveal the contribution of other larger network disturbances beyond those revealed by hypothesis-driven …

A Pilot Study Of The Freeze Response: Physiological Markers Under Threat Versus Safety Video Conditions, Ula Mccarthy

UNF Graduate Theses and Dissertations

This pilot study examined physiological markers of the human freeze response during exposure to threat and safety-based video stimuli. The freeze response is an adaptive defense mechanism characterized by reduced heart rate and heightened sympathetic arousal (Roelofs, 2017; Hagenaars et al., 2014; Sagliano et al., 2014; Hermans et al., 2013). 20 university students were randomly assigned to view either a threatening or safety-based video clip while heart rate and electrodermal activity (EDA) were recorded using Biopac Bionomadix wireless systems. Trauma severity and PTSD symptomatology were assessed through validated self-report measures (BTQ; Schnurr et al., 1999), (PCL-5; Weathers et al., 2013). …

Children's Interpretation Of Others' Faces Covered With Medical Masks, Sevval Cinar

Theses and Dissertations (Comprehensive)

How we recognize and regulate emotions is fundamental to overall health and wellbeing. Emotional recognition and understanding are key to proper communication and emotion regulation. Barriers, such as masks, might have an impact on the way children recognize and interpret others' emotions, and therefore the way they learn, communicate, and regulate their own. The COVID-19 pandemic necessitated widespread mask-wearing, raising questions about its impact on children’s emotional development. Using a sample of children with varying levels of exposure to mask wearing adults (N= 13, ages 4 to 6), we investigated how prolonged mask wearing predicts emotion recognition, particularly …

Don’T Stop Believin’: Emotion Beliefs And Daily Affective Experiences Across Adulthood, Jocelyn A. Rutledge

Theses and Dissertations (Comprehensive)

Emotion control beliefs reflect the extent to which people believe emotions “should” and “can” be controlled and have been linked to psychological well-being. Research has yet to examine age-related differences in these beliefs and their daily associations with affective experiences. The present study examines age differences in daily emotion control beliefs and their within-person associations with positive and negative affect. The study used 14-day daily diary data from an adult lifespan community sample (younger adults: 18-36 years old, N = 72; older adults: 66-92 years old, N = 66). The results revealed that older adults reported …

Terpenes Mitigate Thc-Induced Working Memory Deficits: Behavioural Evidence Of The Entourage Effect Using A 2-Component Operant Memory Task, Lara Mitchell

Theses and Dissertations (Comprehensive)

Most research on cannabis and cognitive function has focused on delta-9-tetrahydrocannabinol (THC). However, this approach overlooks the complex chemical composition of cannabis products consumed by the public, which often includes cannabidiol (CBD) and various terpenes. These additional constituents may interact with THC to modulate its effects, a phenomenon known as the entourage effect. While this theory has gained traction, experimental evidence for the cognitive impact of terpenes in combination with THC remains limited. This study aimed to assess whether terpenes can mitigate THC-induced cognitive deficits using a 2-Component Operant Memory task. Male Sprague-Dawley rats received intraperitoneal injections of either …

Severe Aggression Among Zoo-Housed Coconut (Trichoglossus Haematodus) And Rainbow (Trichoglossus Moluccanus) Lorikeets: Wellbeing Considerations For Free-Flight Aviaries, Emily Simkins

UNF Graduate Theses and Dissertations

As conservation and education institutions, modern zoos balance the needs of animals with the interests of visitors through several strategies which can increase animal wellbeing and improve visitor experience. Environmental enrichment is frequently employed to increase the suitability of anthropogenic environments for zoo-housed animals, such as through walkthrough habitats and free-flight aviaries. While habitats such as these are important for visitor experience and can be enriching to animals, there are also wellbeing considerations for these spaces. Walkthrough habitats can be a potential source of fear and stress for animals, as shown by increased frequencies of vigilance, undesirable behavior, and aggression. …

Beyond My Control: The Role Of Sense Of Control On Cognitive Functioning And Depressive Symptoms In Older Adults, Sabine Lohmar

Graduate Theses, Dissertations, and Problem Reports (ETD)

Depression and depressive symptoms commonly coincide with mild cognitive impairment (MCI) and dementia in older adults (Ismail et al., 2017; Panza et al., 2010), with its prevalence varying based on dementia severity, diagnostic criteria, and dementia subtype (Chi et al., 2015; Ismail et al., 2017; Leung et al., 2021; Lopez et al., 2003). This relationship is hypothesized to exist for a variety of reasons, including that depressive symptoms occur as an emotional response to cognitive functioning (Bennett & Thomas, 2014; Richard et al., 2013). Emotional responses may be explained by a decline in sense of control, or the belief in …

Adolescent Attachment And Anxiety: Examining Implicit Emotion Beliefs And Emotion Regulation As Mediators, Jeanette Pool

Graduate Theses, Dissertations, and Problem Reports (ETD)

Anxiety is a growing issue in adolescents, with teens reporting worse and more severe symptoms in recent years (Kajastus et al., 2023; Solmi et al., 2022). There are several risk factors for developing anxiety symptoms, including cognitive, behavioral, and social factors. Effective emotion regulation (ER) has been shown to be helpful in decreasing anxiety symptom levels (Arbulu et al., 2023; Cho et al., 2019). A better understanding of precursors of ER could aid in prevention of anxiety. ER may stem from our personal beliefs about emotions (Ford et al., 2018; Schroder et al., 2015; Tamir et al., 2007) and to …

What Does It All Mean? Differences In Self-Defining Memories Between Community And Adjudicated Youth, Hannah Elias

Graduate Theses, Dissertations, and Problem Reports (ETD)

Identity development is driven in large part by self-defining memories, or memories though which we base our definition of who we are (Habermas & Bluck, 2000). In adolescence, cognitive skills are gained that allow us to make meaning, or learn lessons and gain insight, from self-defining memories (Bluck & Habermas, 2001; McLean & Thorne, 2003). To determine whether there are differences in their ability to make meaning from their self-defining memories, this study compares narratives of self-defining memories between community youth and adjudicated youth. Additionally, the ability to be specific in self-defining memory recollection may differ between these groups, which …

Parental Behavioral Control Across Domains In Indian And Indian American Families, Avneet Batra

Graduate Theses, Dissertations, and Problem Reports (ETD)

Prior research literature has often found parental behavioral control to have mixed associations with varied adolescent outcomes (Bean et al., 2006; Finkenauer et al., 2005). However, a relatively lesser explored topic of research focusses on the domain specificity of this kind of control and its association with internalizing and externalizing behaviors in sample of Indian and Indian American parents (Arim et al., 2010). The current study adds to the limited literature by emphasizing the five domains of control (e.g., moral, conventional, prudential, personal and overlapping) based on the social cognitive domain theory and explores their association with adolescent adjustment outcomes …

Neurobiological Variables Mediating The Relationship Between Breast Cancer And Sleep Disruption, Brittany Domenique Elliott

Graduate Theses, Dissertations, and Problem Reports (ETD)

Neurobiological Variables Mediating the Relationship between

Breast Cancer and Sleep Disruption

Brittany D. Elliott, MS

Breast cancer is the most commonly diagnosed malignancy in women, with more than two million new cases diagnosed world-wide each year. Improvements in screening technology and diagnostics have increased survival rates, but cancer-associated sleep disruptions persist for the majority of breast cancer survivors well beyond the treatment period. In addition to reducing quality of life, reduced sleep quality is associated with greater incidences of affective dysfunction, reduced treatment efficiency, aggressive cancer progression, increased symptom severity, and increased mortality by all causes. Thus, identifying the variables …

Simulated Slot Machine Gambling In Relation To Sign-Tracking, Polina Krom

Graduate Theses, Dissertations, and Problem Reports (ETD)

The propensity to attribute incentive salience to reward-related cues, or sign-tracking (ST) has been linked to addiction in animal models and some initial human data. The current study explores the role of sign-tracking (ST), as a potential risk factor for problematic slot machine gambling, which abundantly features audiovisual reward-related cues, henceforth sensory features. A sample of healthy participants without gambling problems (n = 30) completed a Pavlovian-to-Instrumental Transfer (PIT) paradigm to assess ST propensity and played on a realistic slot machine simulator consisting of two versions: with sensory features (SF+) and without (SF-). Each game version had fixed bet sizes, …

The Combined Role Of Sexual Selection And Socioeconomic Environment In Explaining Everyday Risk-Taking Behavior In Human Males, Hannah Goodman, Cyril C. Grueter, David A. Coall

Research outputs 2022 to 2026

Sexual selection theory predicts that males, especially in their prime reproductive years, are more risk-prone than females. Risk-taking is a means to convey mate quality or “good genes” to members of the opposite sex or competitive ability to members of the same sex. Therefore, risk-taking should be more common in the presence of potential mates (intersexual selection or female choice) or in the presence of male competitors (intrasexual selection or male–male competition). Risk-taking can also be situated within a life history/ecological perspective, according to which environmental unpredictability promotes more present-oriented and risky behavioral strategies. Therefore, people living in areas of …

The Inward Gaze: White Faculty's Self-Perceptions Of Racial Identity, Privilege, And Its Impact On Pedagogy, David E. Houle

Antioch University Dissertations & Theses

This dissertation examines the evolving self-perceptions of racial consciousness among White faculty in higher education and its impact on pedagogical practices for fostering diversity, equity, and inclusion. This study is guided by Mezirow’s transformative learning theory and Rowe et al.’s White racial consciousness model and uses interpretative phenomenological analysis (IPA) to explore participants’ narratives of White racial identity, disorientating dilemmas, critical self-reflection, and pedagogical transformation. The research highlights key moments of self-reflection and transformation that influence inclusive teaching strategies, such as prioritizing marginalized voices in course content and rethinking classroom dynamics to respond to systemic inequities. The findings reveal how …

Bisexuality: An Individual's Direction Is Society's Detour, Madisyn J. Roberts

Antioch University Dissertations & Theses

This dissertation explores the lived experiences of self-identified bisexual adults through a qualitative, narrative inquiry approach that centers how folx construct their story of sexuality and individual meaning making capacities based on held intersections of identity. Using Queer theory and intersectionality as a theoretical framework, this study investigates and advocates that sexual orientation is not validated or invalidated by its fluidity but aims to understand how bisexuality is an integrative part of an individual’s identity. This dissertation explores how society’s tendency to view sexuality as divided between heterosexuality and homosexuality erases the complexity and spectrum of sexual orientations that exist …

Geriatric Care In Corrections: An Exploratory Study Of Cross-Disciplinary Perspectives On The Needs Of An Aging Prison Population, Cynthia A. Scheiderer

Antioch University Dissertations & Theses

The incarcerated population in the United States is aging. The proportion of adults 55 or older in prison rose from 3% in 1993 to 16% at year-end 2022 (Carson & Sabol, 2016; Carson & Kluckow, 2024). Researchers have consistently found evidence that the prevalence of disabilities and functional impairment is higher among older adults who are incarcerated than among those in the community. As the incarcerated population ages, corrections professionals responsible for providing safety, housing, and health care must respond to the needs of the population. In this qualitative study, 21 corrections professionals from the disciplines of custody, classification, medical, …

My Body My Choice: A Qualitative Study Of Volitional Female Sterilization In The U. S. Latina And Hispanic Female Population, Heather Morris Tuip

Antioch University Dissertations & Theses

This qualitative study, utilizing an interpretative phenomenological analysis methodology, elucidates the experience of Latina and Hispanic women living in the United States who have volitionally undergone sterilization or have sought the procedure out for birth control. Understanding the rich, contextual, lived experience of Latina and Hispanic women through an intersectional framework highlights how cultural influences and contemporary policies on reproductive rights informed their personal choice to undergo a female sterilization procedure. The participants of this study shared how they made meaning of their experiences. Within a homogenous sampling of study participants who share ethnicities and genders, six group experiential themes …

Embracing The Both/And: Learning From The Lived Experiences Of White Facilitators Of Racial Equity Workshops, Alicia M. Wargo

Antioch University Dissertations & Theses

This study focuses on the lived experiences of seasoned White facilitators of racial equity workshops to understand how they navigate the complexity of occupying a White racial identity while working to challenge the belief systems of white supremacy ingrained in themselves and others. Through applying Critical Race Theory as a framework to grounded theory methodology, this study examined whiteness as a sensitizing concept in micro, meso, and macro levels of analysis, situating this dissertation in the theoretical exploration of the multifaceted and pervasive nature of whiteness. Much of the research on racial equity work examines White participants in nascent stages …

Exploring Subjective Cognitive Decline And Ageism: At-Risk Older Adults' Lived Experience, Randal L. Williams

Antioch University Dissertations & Theses

Subjective Cognitive Decline (SCD), the self-perceived decline in cognitive abilities, is recognized as a preclinical marker for neurocognitive disorders (Jessen et al., 2014). Understanding the contextual factors informing SCD experience remains a research priority in this domain. At-risk older adults have heritable markers associated with dementia. Chronic exposure to embedded ageism burdens allostatic load (AL) and exacerbates epigenetic risk for cognitive decline (Levy, 2022; McEwen, 2020; Miller et al., 2021). The current qualitative study explored how ageism shapes the lived experience of SCD among at-risk older adults. Semi-structured interviews were conducted with 12 participants, all doctoral level clinical practitioners, aged …

Psychology's Questionable Research Fundamentals (Qrfs): Key Problems In Quantitative Psychology And Psychological Measurement Beyond Questionable Research Practices (Qrps), Jana Uher, Jan Ketil Arnulf, Paul T. Barrett, Moritz Heene, Jörg Henrik Heine, Jack Martin, Lucas B. Mazur, Marek Mcgann, Robert J. Mislevy, Craig Speelman, Aaro Toomela, Ron Weber

Research outputs 2022 to 2026

Psychology's crises (e.g., replicability, generalisability) are currently believed to derive from Questionable Research Practices (QRPs), thus scientific misconduct. Just improving the same practices, however, cannot tackle the root causes of psychology's problems—the Questionable Research Fundamentals (QRFs) of many of its theories, concepts, approaches and methods (e.g., psychometrics), which are grounded in their insufficiently elaborated underlying philosophies of science. Key problems of psychological measurement are critically explored from independent perspectives involving various fields of expertise and lines of research that are well established but still hardly known in mainstream psychology. This comprehensive multi-perspectival review presents diverse philosophies of science that are …

Legislating Trans Lives: An Archival Analysis On Trans Canadian Rights, Charlie E. C. Davis

Theses and Dissertations (Comprehensive)

Previous research has outlined trans histories within the United States and Europe, illustrating historic transphobia, oppression and the origins of gender identity clinics. This type of historical literature is limited in the Canadian context, with more contemporary research demonstrating that trans people experience significant barriers to accessing healthcare, aversive health outcomes, and high rates of discrimination. Trans activists and advocates have always been and continue to resist these oppressive systems and have worked to improve the social and physical wellbeing of trans people in Canada. Utilizing archival data of trans activism and community mobilizing, I sought to address the gap …
