A Social Learning Approach To The Examination Of The Temporal Directionality Between Parenting Behavior And Early Adolescents' Affect., Shelby M. Burton

Electronic Theses and Dissertations

This study contributes to current literature by being the first to longitudinally examine the relation between early adolescents’ negative and positive affect and specific parenting behaviors. The five parenting behaviors examined in the current study are rooted within the social learning theory constructs of effective discipline (i.e., corporal punishment, inconsistent discipline), positive involvement (i.e., parental involvement), monitoring (i.e., poor monitoring and supervision), and social skills encouragement (i.e., positive parenting). Two research questions were addressed: (1) how are parenting behaviors at baseline associated with early adolescent-reported NA and PA at a later timepoint, and (2) how are early adolescents’ NA and …

Factors Related To Cognitive Reserve In Healthy Older Adults, Ann Tram Nguyen

Loma Linda University Electronic Theses, Dissertations & Projects

Background. Physical and cognitive impairments are two of the most prevalent age-related conditions, with evidence that both factors interact prior to or concurrently with the earliest detectable stages of cognitive impairment. Cognitive reserve (CR) allows an individual to cope more successfully with age-related brain and functional changes and is associated with better cognitive function and reduced risk of cognitive decline. However, it remains unclear to date the specific roles of individual markers of CR, and whether or not this relationship is modified by genetic risk (ApoE-4 genotype) and/or physical function. Method. We assessed cognitive functioning (global cognition, psychomotor …

Symptoms, Executive Function, Mentalization, And Functional Capacity In Schizophrenia, Yasmine Kolahi

Loma Linda University Electronic Theses, Dissertations & Projects

One of the core features in schizophrenia is a deficit in real-world functioning as expressed through difficulties in the ability to work, engage in social relationships, attend to self-care, and participate in recreational and community activities. Due to this impact on overall quality of life, experts have investigated possible links between the observable symptoms of the illness, such as negative symptoms, with functional outcomes. Ample research has shown that neurocognition is one possible candidate, although fewer studies have explored the specific contributions of executive functioning, or the cognitive process associated with top-down regulation of cognition and behavior. The links between …

Exploration Of Patient Variables And Characteristics Best Suited For Medical Marijuana Treatment For Anxiety And Depressive Disorders, Corey Gazoo

Dissertations

Individuals with posttraumatic stress, anxiety and depressive disorders are currently being prescribed medical marijuana as a treatment in many states across the United States. However, marijuana is still considered a schedule one narcotic by the Drug Enforcement Administration and federal government, which provides several barriers and challenges to conduct research such as approval from the U.S. Food and Drug Administration and following guidelines from the National Institute on Drug Abuse issued by the DEA. Additionally, individuals prescribed medical marijuana for mental health disorders are not always thoroughly instructed on the type of medical marijuana, the dosage, and how frequently to …

Predicting Parent Attendance For Group-Delivered Pcit Workshops In Head Start Centers, Jennifer Tannehill

Dissertations

Group PCIT was offered to parents of Head Start children as part of a larger study that investigated the Impact of a Preschool Obesity Prevention (IPOP) Program Enhanced with Positive Behavioral Supports. The dependent variable (DV) in this study was number of group PCIT sessions attended. The independent variables were marital status, income, education level, parenting practices measured by the Alabama Parenting Questionnaire-PR, and responses from the Caregiver Feeding Style Questionnaire. Predictions were made regarding the impact each of these variables had on attendance to group PCIT sessions. An ordinal logistic regression model was used to analyze the data. No …

Latent Variables Predicting Drug Use In Adolescents With High Versus Low Protective Factors, Jessica Jorgenson

Dissertations

The present study utilized archival data provided from the Minnesota Student Survey (2013). The study consisted of two levels of analysis. The first level involved the development of measurement models for various latent constructs (i.e., disaffiliation, normalized use, internalizing behaviors, and externalizing behaviors). Utilizing Structural Equation Modeling (SEM), the second level applied the observed (i.e., abuse) and measured latent variables to the prediction of the outcomes of interest (i.e., a latent variable estimate of substance use) for middle- and high school-aged youth. Models for adolescent girls and boys were examined separately based on sex and high vs low protective factors. …

The Power Of Presentation: How Attire, Cosmetics, And Posture Impact The Source Credibility Of The Female Expert Witness, Alexandra Repke

Dissertations

While previous research has examined behavior-based presentation styles of the female expert witness in light of source credibility, further research is required to examine the effect of other modifiable factors on her credibility, since perceived credibility affects the intermediate judgments that lead to ultimate legal decisions. This study investigated the impact of both behavior-based (i.e., posture) and appearance-based (i.e., attire and cosmetic use) factors on the female expert witness’ source credibility Model attractiveness served as a covariate in this study. A four-way (2 x 2 x 2 x 2) between-subjects analysis of covariance (ANCOVA) revealed that, beyond an effect of …

Attachment Quality Across Contexts: The Mediating Role Of Cognitive-Affective Traits, Christian Ammons

Dissertations

Attachment quality throughout the lifespan has been found to be impacted by a variety of factors including prior attachments with parents and other adults (Rholes, Simpson, & Friedman, 2006). The mechanisms that impact the transmission of attachment to parent-child attachment quality has not been fully explored. Individual differences such as traits involving appraisal of self and others and affective components have been found to be important in relationship functioning across contexts (Eisenberg, 2000). Thus, the current study evaluated the relationship between adult attachment quality and parent-child attachment quality and specifically examined the mediating effects of cognitive-affective traits (i.e. trait forgiveness, …

Serotonin 1b/1a Receptor Modulation On Behavioral Flexibility In C57bl/6j Mice, Brandon L. Oliver

Electronic Theses, Projects, and Dissertations

Pharmacological activation of the 5-HT1B and 1A receptors has been implicated in OCD-like behaviors in rodents such as increased perseverative circling, checking behaviors, and locomotor stereotypy. However, little is understood about the effects of 5-HT1B and 1A receptor activation on behavioral inflexibility, a common symptom associated with OCD. The present study utilized the 5-HT1B/1A receptor agonist RU24969 at 0.01, 0.1, and 1.0 mg/kg to test three hypotheses. The first hypothesis predicted RU24969 would lead to a dose-dependent impairment on behavioral flexibility in C57BL/6J mice. It was also predicted that male C57BL/6J mice would be more inflexible than female C57BL/6J mice …

Interpersonal Needs And Suicide Risk: Examining Indirect Effects Of Internal Hostility And Feeling Forgiven, Kelley C. Berto

Electronic Theses and Dissertations

Suicide is a national public health concern, and unmet interpersonal needs (i.e., perceived burdensomeness, thwarted belongingness) may contribute to enhanced risk. However, mechanisms of action and certain protective variables are not well understood. The present study examined simple mediation models, with internal hostility as a mechanism of action between interpersonal needs and suicide risk. Additionally, our study examined the moderating role of various aspects of receiving forgiveness on the association between interpersonal needs and internal hostility in these simple mediation models. A community-based convenience sample was surveyed (N=712). Our findings indicated that internal hostility partially mediated the association …

Forgiveness, Gratitude, Humility, And Spiritual Struggle: Associations With Religious Belief Status And Suicide Risk, Benjamin B. Hall

Electronic Theses and Dissertations

Religion is a known contributor to suicide risk, with both positive and negative effects. Negative religious experiences, such as spiritual struggle, can exacerbate suicide risk. Alternatively, religion may promote positive psychological characteristics associated with reduced suicide risk, such as forgiveness, gratitude, and humility. However, research has yet to assess how religious changes, including conversion and deconversion, affect the linkage between religious risk and protective factors and suicidal behavior. We conducted three studies assessing these associations across four belief status groups: life-long religious believers, former religious non-believers who now believe, life-long religious non-believers, and former religious believers who no longer believe. …

Attachment And Intimate Partner Violence In Predominantly Hispanic Young Adult Couples, Deanna Pollard

Theses and Dissertations

Some research suggests that conflicting insecure attachment needs between romantic partners exacerbate the association between insecure attachment dimensions and physical intimate partner violence (IPV) perpetration in men and women. However, the current literature examining this association are not without their limitations (i.e., small sample sizes, collapsing both partners' reports together to create their IPV variables, predominantly White samples, and utilizing attachment instruments that do not assess attachment dimensions directly). The present study aimed to address some of the limitations in previous research by examining the association between partners' opposing insecure attachment dimensions and male and female-perpetrated physical IPV in a …

The Influence Of Human Attentional State And Familiarity On Bengal Tiger (Panthera Tigris Tigris) And Siberian Tiger (Panthera Tigris Altaica) Sociability, Jenna J. Dail

Graduate Theses/Dissertations

An essential element of an animal’s character is sociability (Gosling and John, 1999) and is demonstrated through interactions with other individuals (Capitanio, 2002). Although it is common to believe that domestic cats are not social beings, they have exhibited variance in solitary and social behavior, contingent on their environment and history (Turner, 2014). Much of the research on sociable behavior of animals has been completed between conspecifics. There has been less examination into interspecies sociability, and that which has been reviewed is focused on the relationship between humans and the domestic dog (Udell et al., 2010). Following this work, Vitale …

Why Am I Like This? An Examination Of The Impact Of Early Childhood Experiences On Adult Attachment Style, Amaris Clay

Graduate Theses/Dissertations

Early childhood experiences and parental relationships have a lasting influence on future interpersonal relationships and the associated behaviors (Cortazar and Herreros 2010; Raby et al. 2015; Simons et al. 2014; Treger and Sprecher 2011). The proposed study is investigating the complex links between adverse childhood experiences, parenting style, and attachment style. The purpose of this study was to examine the lasting impact of early childhood factors and how they affect relationships in adulthood. The study intends to replicate previous research on parenting style and attachment style. The results of this study will add to the body of research centered on …

The Moderating Role Of Social Support In Stigma And Symptoms Of Anxiety And Depression, Taylor Phillips

Undergraduate Honors Theses

In this study, we examine the relationship between having a support system and the stigma individuals face with depression and anxiety symptoms. The aim of this study was to examine if having a support system acts as a buffer between perceived stigma and mental health symptoms. For this study, I conducted an online survey to measure symptoms of depression and anxiety, experiences with both perceived and internalized stigma, and social support. While 93 total participants engaged in the survey, only 52 fully completed the survey and passed two attention-check questions to ensure no invalid participation (e.g., BOTS) were present. In …

Inducing Proactive Control With High Load Ax-Cpt, Mina Selim

Electronic Theses, Projects, and Dissertations

A central hypothesis of cognitive control is that goal maintenance operates via two distinct modes: proactive control and reactive control (Braver, Gray, & Burgess, 2007). Individuals using a proactive strategy, focus on actively maintaining goal-relevant information in memory, whereas reactive individuals store goal-relevant information and retrieve it when cues are present. This theoretical framework for understanding the sources of variation in cognitive control is termed the dual mechanisms of control (DMC). When compared to high working memory capacity (WMC) individuals, low WMC individuals tend to utilize reactive control more often. However, some factors influence an individuals’ bias towards one type …

The Relationship Between Sex Role, Mindfulness, Perceived Stress, Anxiety, And Flow In Team Sport Female Athletes, Vanessa Chafos

Seton Hall University Dissertations and Theses (ETDs)

In recent years, studies have emerged that support the use of mindfulness interventions to enhance sport performance (Cathcart et al, 2014; Gardner & Moore, 2012; Jekauc et al., 2017; Kee & Wang, 2008; Moen et al., 2015). Among these studies, there is a gap in the literature in regards to sex role and mindfulness, perception of stress, and ability to reach a flow state. This study discusses current sport psychology literature and explores the relationship between sex role, mindfulness, perceived stress, anxiety, and flow among 185 team sport female athletes. Correlational Analyses from this study indicated that there is a …

Is Pristine Inner Experience Linked To Biology? An Examination Of Experience Across The Menstrual Cycle Among Women With Premenstrual Distress, Alek E. Krumm

UNLV Theses, Dissertations, Professional Papers, and Capstones

The link between mind and biology is intuitively known: We notice changes in our mood and behavior when hungry, in pain, or under the influence of substances. Yet, the specifics of this link—for example, how changes in biology affect directly apprehended conscious experience— are not well known. The present study was an exploratory attempt toward filling that gap by using a state-of-the-art, beeper-driven method for exploring directly apprehended conscious experience (Descriptive Experience Sampling; DES) across one of the most predictable and wellknown biological cycles: menstruation. We screened approximately 300 college women to identify those who reported clinically significant symptoms of …

Modeling Real And Fake News Sharing In Social Networks, Abishai Joy

Boise State University Theses and Dissertations

Online media is changing the traditional news industry and diminishing the role of journalists, newspapers, and even news channels. This in turn is enhancing the ability of fake news to influence public opinion on important topics. The threat of fake news is quite imminent, as it allows malicious users to share their agenda with a larger audience. Major social media platforms like Twitter, Facebook, etc., are making it easy to spread fake news due to the minimal moderation/ fact-checking on these platforms.

This work aims at predicting fake and real news sharing in social media. Specifically, we employ a multi-level …

Doing More With Less: A Quantitative Analysis Of Mindfulness, Meditation, Sustainable Consumption Awareness And Practice Among University Undergraduates, Teresa Van Horn

Dissertations

ABSTRACT

Climate change, overconsumption, air, and water pollution continue to be pressing issues for society. Given the significant impact of overconsumption, the search for strategies to promote more sustainable behavior has become a topic for investigation. Universities are uniquely positioned to help students work toward sustainable solutions. This research explored the role of mindfulness in university students' sustainable consumption awareness and practice as there are gaps in the literature concerning definitions, constructs, and research regarding mindfulness and sustainable consumption.

To address these disparities, this research used stepwise regression analysis to investigate the extent to which mindfulness and select demographic measures …

Non-Affirmation As A Moderator Between Social Support And Quality Of Life For Transgender Populations, Michael Evitts

Dissertations

This research builds upon scholarship exploring the quality of life of transgender populations. Knowledge on quality-of-life (QOL) for transgender populations has been limited due to the fact that most studies have focused on gender affirming medical procedures as interventions (Nobili et al., 2018). Other protective factors, such as social support, have been identified in the literature but have been defined in broad terms. The purpose of the study was to better understand additional factors that promote QOL and psychological well-being, specifically social support. It is unclear how non-affirmation of gender identity affects the protective effects of social support for QOL. …

Exploring Generational Difference Of Acculturation, Ethnic Identity And Racial Identity In Liberian Immigrants And Their Children Living In The United States, Breezie J. Gibson

Dissertations

Prior literature on immigrants has focused on the impact of acculturation for groups such as Asians and Hispanic or Latinx immigrants (Orjiako & So, 2014; Sall, 2019). Compared to these two groups, the literature on Black immigrants’ experience of acculturation is scarce. In addition to the minimum visibility of Black immigrants in the acculturation literature, there is also limited knowledge relating to differences in the ethnic identity and racial identity of Black immigrants because these immigrants are often grouped monolithically with minimum attention to their diverse countries of origin. Understanding the influence of acculturation, ethnicity, and race is important because …

Preclinical Behavioral Assessment Of Chronic, Intermittent Low-Dose Psilocybin In Rodent Models Of Depression And Anxiety, Harmony I. Risca

Dissertations

Recent studies have demonstrated the clinical efficacy of psychedelic-assisted psychotherapy for treatment-resistant depression and anxiety. Amidst the overall success of recent clinical trials using a single high dose of psilocybin, anecdotal reports indicate anxiolytic and antidepressant effects following a repeated low dose regimen. As therapeutic outcomes are often tightly intertwined with the individual’s subjective experience, animal models are used as objective measures to investigate the underlying mechanisms responsible for the putative antidepressant/anxiolytic effects of psychedelics. Three rodent models predictive of anxiolytic or antidepressant effects were used to evaluate effects of chronic intermittent low dose (CILD) psilocybin treatment; the Light/Dark conflict …

Stability Of Hippocampal Subfield Volumes After Trauma And Relationship To Development Of Ptsd Symptoms, C. N. Weis, E. Kate Webb, Ashley A. Huggins, Maddy Kallenbach, Tara A. Miskovich, Jacklynn M. Fitzgerald, Kenneth P. Bennett, Jessica L. Krukowski, Terri A Deroon-Cassini, Christine L. Larson

Psychology Faculty Research and Publications

Background

The hippocampus plays a central role in post-traumatic stress disorder (PTSD) pathogenesis, and the majority of neuroimaging research on PTSD has studied the hippocampus in its entirety. Although extensive literature demonstrates changes in hippocampal volume are associated with PTSD, fewer studies have probed the relationship between symptoms and the hippocampus’ functionally and structurally distinct subfields. We utilized data from a longitudinal study examining post-trauma outcomes to determine whether hippocampal subfield volumes change post-trauma and whether specific subfields are significantly associated with, or prospectively related to, PTSD symptom severity. As a secondary aim, we leveraged our unique study design sample …

Inclusion Toward Transformation: Psychosocial Disability Advocacy And Global Mental Health, Justin M. Karter

Graduate Doctoral Dissertations

The Movement for Global Mental Health (MGMH) has been met with criticism for reifying Western conceptions of mental disorders and diverting resources from the investigation, intervention, and education regarding the social determinants of mental health. Advocates identifying as a person with a psychosocial disability are organizing to transform the MGMH from a top-down, individualized, and universal approach toward a rights-based conception that accounts for the cultural, political, and economic conditions that produce distress and disability. Using a qualitative, hermeneutic, interpretative-phenomenological analysis (IPA), this research study focused on how people with a lived experience of mental distress and treatment come to …

Subjective Age And Inflammation Risk In Midlife Adults: Findings From The Midlife In The United States (Midus) Studies, Andree Hartanto, Nadyanna M. Majeed, Wee Qin Ng, Colin Kai Ning Chai, Verity Yu Qing Lua

Research Collection School of Social Sciences

Recent studies have suggested that subjective age—a subjective evaluation of one's own age—is a promising construct in gerontology that may contribute our understanding of risk for immune dysfunction. Nevertheless, studies documenting the association between subjective age and inflammatory biomarkers remain limited and provide mixed findings. In the present study, we revisited the relation between subjective age and systemic inflammation by utilizing a range of well-established inflammatory biomarkers (C-reactive protein, interleukin-6, fibrinogen, E-selectin, and intercellular adhesion molecule 1) through the collection of fasting blood samples before breakfast. In a large-scale dataset of midlife adults (N = 1800), we found some evidence …

The Influence Of Emotion Regulation, Maladaptive Coping, And Criminal Thinking On Maladaptive Behavior, Alondra Avila

Open Access Theses & Dissertations

Emotion regulation is a cognitive process that occurs due to emotional stimuli in the environment that promotes cognitive or behavioral action to soothe negative emotions. Emotion regulation can affect decision making that promotes maladaptive behavior, similar to criminal thinking. Criminal thinking patterns can be categorized as a form of maladaptive cognitive coping that promotes maladaptive behavior. The association between emotion regulation, criminal thinking, and maladaptive behavior is further explored. A total of (N = 227) MTurk workers participated in a cross-sectional study. Maladaptive emotion regulation and coping predicted willingness to engage in maladaptive behavior. Deficits in emotion regulation were further …

Neurotrophic Factor Genetics Of Cognitive Progression And Neuropsychiatric Symptom Presentation In Alzheimer's Disease And Related Disorders, Joshua Matthew Matyi

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The Cache County Study on Memory in Aging (CCSMA) and subsequent Dementia Progression Study (DPS) were two research studies that took place in Cache County, Utah. These studies followed 5092 participants aged 65 or older for approximately 12 years and looked at risk and protective factors for dementia, including Alzheimer’s disease. One of the factors investigated was genes that are known to influence brain health, such as brain-derived neurotrophic factor (BDNF), a protein found in the brain that helps with the survival of brain cells.

BDNF genes have been shown to be associated with Alzheimer’s disease and related dementia (ADRD) …

Extended Maternal And Paternal Hereditary Risk For Alzheimer’S Disease Examined By Sex In A Sample Of Community Dwelling Older Adults In Cache County, Utah, Elizabeth K. Vernon

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

More than 6 million Americans are living with Alzheimer’s Disease (AD) and this number is expected to rise and surpass 12.7million individuals by the year 2050. Currently there is no cure for the disease and prior research has focused on prevention by identifying risk factors. Known risk factors associated with AD include older age, female sex, genetics, family history of AD, genotype of the apolipoprotein E (APOE) gene, and vascular risk factors (e.g., cholesterol, hypertension) and conditions or events (e.g., CHF, stroke). The effects of many of the above risk factors have differed in men and women, but few studies …

Risk Factors For Early And Late Onset Depression And Subsequent Risk For Alzheimer's Disease And Related Dementias In An Older Adult Population, Jordan Kugler

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The Cache County Study on Memory in Aging (CCSMA) was a research study that followed 5092 participants aged 65 or older over the course of 12 years, examining risk and protective factors for dementia. One of these factors was depression history, which has evidence for a connection with dementia, such that those with a history of depression are more likely to develop dementia later in life. However, the existing literature has yet to examine sex differences, genetic and psychosocial factors that contribute to earlier or later onset of depression and how these factors in turn might later increase risk for …
