Gaining Computational Insight Into Psychological Data: Applications Of Machine Learning With Eating Disorders And Autism Spectrum Disorder, Natalia Rosenfield

Computational and Data Sciences (PhD) Dissertations

Over the past 100 years, assessment tools have been developed that allow us to explore mental and behavioral processes that could not be measured before. However, conventional statistical models used for psychological data are lacking in thoroughness and predictability. This provides a perfect opportunity to use machine learning to study the data in a novel way. In this paper, we present examples of using machine learning techniques with data in three areas: eating disorders, body satisfaction, and Autism Spectrum Disorder (ASD). We explore clustering algorithms as well as virtual reality (VR).

Our first study employs the k-means clustering algorithm to …

A Brief Online Acceptance And Commitment Training For Enhancing Outcomes Of A Cultural Competence Intervention, Elizabeth Tish Hicks

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

In an increasingly diverse and multicultural society, there is a pressing and practical need for interventions to help professionals improve their cultural competence. Cultural competence trainings that target psychological flexibility in addition to knowledge, awareness, and skills may produce more efficacious results. The current study will examined the utility of targeting psychological flexibility (the ability to maintain contact the present moment and current internal experiences and to choose contextually appropriate, values-consistent behaviors, regardless of what one’s internal experiences are) as a process to enhance the impact of a cultural competence intervention with an Acceptance and Commitment Training (ACT)-enhanced cultural competence …

Gratitude In Adolescents: Examining The Role Of Attachment, Parental Gratitude, And Discounting, Savannah C. Rupp

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

From early childhood, parents often teach their children to use their manners by saying "Thank you"; however, are there any benefits from experiencing gratitude during youth? Understanding the relationship between gratitude and other areas, such as happiness and decision-making, can potentially help researchers in planning interventions for youth. The purpose of this study was to determine the relationship between gratitude and decision-making in youth, as well as the role of maternal gratitude and the mother-child attachment in determining gratitude in youth. Two hundred four participants (102 mothers, 102 adolescents) completed an online survey. Mothers and adolescents completed two gratitude questionnaires …

Rumination And Quality Of Life Among Northern Plains Indians, Devon S. Isaacs

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Native Americans (NAs) share unique risk factors for poor mental health. In response, mental health providers must address barriers to treatment while making the most of low resource situations. One way to increase usefulness of treatment is to address the mechanisms underlying multiple mental health disorders. Rumination is a style of thinking marked by repeated thoughts about distress and is well-recognized as a diagnostic factor for underlying disorders in the general population. Secondary data from the Mood Disorder Assessment Validation with Northern Plains Indians (NPI) pilot study was used to examine the relationship between rumination and anxiety, depression, and substance …

College Prescription Opioid Misuse: An Exploration Of Social Learning, Social Control, And Strain Theories, Julie Murray

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Prescription opioids, when used as medically intended, can be effective in pain management. However, the consequences and costs of widespread misuse of prescription opioids in the United States are cause for concern. Prescription opioids are related to increased risk of death and injury. Young adults, between the ages of 18 and 25, have the highest rates of misuse nationally and within this age group, college students may be particularly at risk. In order to effectively curb the growing misuse of prescription opioids within college populations, we must have a better understanding of the factors that potentially lead to misuse.

Stereotypic Morality: The Influence Of Group Membership On Moral Foundations, Jeremy R. Winget, R. S. Tindale

Psychology: Faculty Publications and Other Works

Today’s modern world affords many benefits, one of which is the ability to have near-instantaneous interactions with groups and cultures other than our own. Though advantageous in many situations, one challenge for these groups is navigating what they perceive to be right and wrong in a cooperative manner despite having different modes of morality. Moral foundations theory holds groups use the same moral foundations to guide their judgments and decision making, but there has been little research on how the perception of these foundations differs within and between groups. Thus, the current study examined how moral foundations operate from a …

Resilience And The Mental Health Of Bullying Victims: The Role Of Peer Relationships On The Relation Between Bullying Victimization And Social Anxiety, Michelle Catherine Zochowski

UNLV Theses, Dissertations, Professional Papers, and Capstones

Bullying is a pervasive issue in today’s schools that has a significant impact on the mental health of students. Resilience has a positive impact on the outcomes related to facing adversity including bullying. The following dissertation study asks whether the relation between bullying victimization and social anxiety differs as a function of resilience and gender. It was hypothesized that bullying victims with increased resilience would show lower levels of social anxiety, as would students that report their gender as female. Chapter one discusses the significance of the problem, defines relevant constructs, and introduces the problem statement. Chapter two outlines the …

Implicit Bias And Voluntarily Childfree Adults, Virginia Elizabeth Powell

Electronic Theses and Dissertations

This quantitative study aimed to determine if there is a negative bias towards voluntarily childfree adults or an association of negative views and attitudes with voluntarily childfree adults, controlling for other participant characteristics such as race, religion, or sexual orientation. At this stage in the research, voluntarily childfree adults are generally defined as legal adults who have the intention to remain childfree for the rest of their lives, due to reasons other than fertility issues. A negative view or bias is defined as any attitude which is not a desirable interpretation of behavior or lifestyle. A negative bias against voluntarily …

Can A Brief Online Intervention Change Low-Income Caregivers’ Reported Use Of Spanking? A Randomized Controlled Trial, Hilary L. Richardson

Dissertations

Spanking is commonly used by parents (64-94%) in the United States as a strategy for managing undesirable child behaviors. Research has found that the use of spanking is particularly high among young mothers, low-income parents, and African American families. Decades of literature on the use of spanking has identified abundant detrimental outcomes for children such as increased externalizing behaviors, decreased long-term compliance, and less guilt following misbehavior, as well as serious outcomes in adulthood such as depressed mood and alcohol/drug use. There is also a risk for spanking to escalate to physical abuse. Thus, safer, more effective discipline strategies are …

Testing A Model Of Sexual Minority Orientation In Individuals With And Without The Broad Autism Phenotype, Lydia Ruth Qualls

Psychology Theses & Dissertations

Individuals with Autism Spectrum Disorder (ASD) and the Broad Autism Phenotype (BAP) are more likely than individuals with typical development (TD) to report a sexual minority orientation (e.g., Bejerot & Eriksson, 2014; DeWinter et al., 2017; Qualls, Hartmann, & Paulson, 2018). There has been no research on how existing theories of sexual orientation might explain the development or increased likelihood of sexual minority orientation in these individuals. The aim of this study was to operationalize and test the fit of an existing model of sexual orientation (Worthington, Savoy, Dillon, & Vernaglia, 2002) in individuals with TD, BAP, and ASD.

Assessment Of Coordination And Proprioception In Youth With Autism Spectrum Disorder, Taylor Kristina Jones

Human Movement Studies & Special Education Theses & Dissertations

Autism spectrum disorder (ASD) is characterized by social and communicative delays. It is known that those with ASD exhibit lower activity levels and decreased proprioception to some extent. The biomechanics of movement in ASD has not been assessed thoroughly enough to provide information on ASD specific movement patterns, and no studies have been performed examining work and recovery. The purpose of this study is to examine whether 1) inter-limb and intra-limb coordination patterns during walking and running differ between youth with ASD and neurotypical sex, age, and BMI-matched controls. Youth with ASD (N=8) and their BMI, age, and sex matched …

Morally Injurious Experiences, Trauma-Related Guilt, And Substance Use Among Iraq And Afghanistan Combat Veterans, Allison T. Battles

Psychology Theses & Dissertations

Exposure to morally injurious experiences (MIEs), or stressors that transgress deeply held moral beliefs, are risk factors for hazardous alcohol use and drug abuse among combat veterans. Guilt following a traumatic event also has a negative impact on veteran’s mental health and is conceptualized as a core symptom of moral injury that may elicit secondary outcomes, including substance use. Significant gaps remain in our understanding of the way MIEs and trauma-related guilt relate to hazardous alcohol use and drug abuse symptoms. Most prior research on MIEs and substance use have been limited to veterans sampled from the general population and …

A Phenomenological Investigation Of Counselors’ Experiences With Clients Affected By Problematic Internet Pornography Use, Kendall R. Sparks

Counseling & Human Services Theses & Dissertations

The primary researcher conducted a phenomenological study examining the experiences of licensed professional counselors (n = 8) who have worked with clients affected by problematic Internet pornography use. There were five female participants with an average age of 49 and three males with an average age of 63. All eight participants identified as Christian. Four participants reported their highest level of education was a Master’s degree, three participants reported holding a Ph.D. and one participant reported holding an Ed.S. Through semi-structured interviews, the primary researcher of this study sought to gain an understanding of how counselors were experiencing and navigating …

The Role Of Masculinity In The Development Of Capability For Suicide, Claire Houtsma

Dissertations

Males account for over two-thirds of suicide deaths annually. Additionally, more than 50% of American suicide deaths annually are firearm-related. Suicide risk is elevated within firearm owning households and men are more likely to own firearms, which suggests that male firearm owners are at disproportionate risk for suicide. Prior research has argued that certain stereotypically male traits (e.g., lack of help-seeking) may explain sex differences in suicide death; however, this remains a poorly understood phenomenon. Male gender norms (e.g. physical toughness, self-reliance) may contribute to the development or expression of capability for suicide, primarily through their impact on behavior. The …

Change In Implicit Alcohol Associations Over Time: Moderation By Drinking History And Gender, Scott A. Baldwin, Kristen P. Lindgren, Kirsten P. Peterson, Reinout W. Wiers, Bethany A. Teachman

Faculty Publications

Implicit measures of alcohol-related associations or implicit alcohol associations are associated with drinking outcomes over time and can be understood as vulnerability markers for problem drinking. Longitudinal research remains rare, leaving open questions about how implicit alcohol associations themselves change over time and what factors moderate that change. We examined these questions with data from a larger study of first and second year U.S. college students. We investigated how these implicit alcohol associations change over time and potential moderators of those changes (gender, lifetime drinking history, family history of problem drinking, and class standing). A sample of 506 students (57% …

Symptom Presentation Of Sexually Abused Youth: Associations With Abuse Attributions, Brittany Biles

Department of Psychology: Dissertations, Theses, and Student Research

Child sexual abuse (CSA) outcomes are heterogeneous. Some victims display a combination of externalizing behaviors (e.g., aggression) and internalizing symptoms (e.g., depression), while others present with minimal symptoms (Domhardt, Munzer, Fegert, & Goldbeck, 2015). Among the factors that have been explored as relating to CSA outcomes are child characteristics (e.g., age; Dube et al., 2005), abuse-specific variables (e.g., abuse severity; Stroebel et al., 2012), and family variables (e.g., familial social support; Ryan, Kilmer, Cause, Watanabe, & Hoyt, 2000). Although much of the literature supports these factors as contributing to outcomes following CSA, conclusions have been inconsistent. Research has begun to …

Consider The Agent In The Arthropod, Nicolas Delon, Peter Cook, Gordon Bauer, Heidi Harley

Animal Sentience

Whether or not arthropods are sentient, they can have moral standing. Appeals to sentience are not necessary and retard progress in human treatment of other species, including invertebrates. Other increasingly well-documented aspects of invertebrate minds are pertinent to their welfare. Even if arthropods are not sentient, they can be agents whose goals—and therefore interests—can be frustrated. This kind of agency is sufficient for moral status and requires that we consider their welfare.

Using Therapeutic Photography Techniques To Increase The Wellbeing Of College Students, Licia Tourigny, Ivelina Naydenova

Journal of Counseling and Psychology

In this study the benefits of therapeutic photography techniques were analyzed for people with varying degrees of depression and anxiety. In study 1, participants were placed in groups after taking the Beck’s Depression Inventory. After they were placed in groups, they also took Beck’s Anxiety Inventory and the Life Satisfaction Scale. For four weeks, participants were asked to take pictures of what makes them happy and share and discuss them with their groups. After four weeks, they took all three inventories a second time. We found significant results between the pretest and posttest scores of the depression and anxiety inventories; …

His And Hers: Gender-Specific Design In Mid-Twentieth Century North America Through Film And Television, Morgan O'Shaughnessy

Architecture Masters of Science Program: Theses

The built environment exists as a variety of ‘spaces’ which are constructed by, and for, the people who occupy them. What is the relationship between social constructs of gender and our built environment in the 20^th century? How does film and television representing the mid-20^th century exemplify this relationship? The overall theme of this topic will include a positive relationship between social gender constructs and our built environment. Through the exploration of select film and television, this study attempts to answer the question of how gender-focused design reinforces traditional gender roles in North American society in mid-20^{th …}

Online Civic Engagements Among College Students: Exploring Well-Being, Tanupreet Suri

Individual, Family, and Community Education ETDs

Ways in which college students use social media for civic engagements and how that usage interplays with their identity development and general well-being have been explored in this study. Civic engagement among college students is imperative to their growth and development. Additionally, social networking sites (SNS) have a great potential for fostering a sense of community and enhancing wellbeing. Thus, how college students’ online civic engagement and general wellbeing interplay was examined. This study employed an interpretative phenomenological analysis (IPA) alongside photo elicitation to explore the experiences of college students. Key findings suggest online civic engagements interplays with college students’ …

Examining Patterns Of Executive Functioning Across Dimensions Of Psychopathology, Scott Roye

LSU Doctoral Dissertations

Executive functioning is a multifaceted collection of higher-order cognitive processes used to perform goal-oriented tasks. Although this construct is heavily researched, a major issue regarding the current literature stems from the influence of task impurity, which interferes with how executive functioning performance is interpreted. Additionally, while executive functioning has been previously explored in clinical populations, less work has evaluated this topic measuring dimensional psychopathology. The present study sought to examine the role of executive functioning, as it relates to dimensional psychopathology. Data was analyzed from a total of 731 individuals between the age of 18-59 years who took part in …

Bullying By Teachers: Preventative Measures In Hogwarts, Zenobia Allen (1), Shannon Eshman (1), Ashley Mayer (1), Caitlin Schwartz (1)

Student Bibliography

In our case study, the Battle of Hogwarts, we decided to address the problem of bullying by teachers against students in the forms of discrimination, indoctrination, and maltreatment of students and how that might result in negative educational outcomes such as a lack of self-esteem, racist beliefs, discrimination, and stress. Students who were bullied before, during, and after the battle may have long-lasting problems that resulted from such instances of mistreatment. For example, professors such as Snape and the Carrows discriminated against Muggle-born students like Hermione. During the take-over of Hogwarts by the Death Eaters, Defense Against the Dark Arts …

Critical Wisdom In The Training Of Clinical Psychologists, Ross B. Renfroe

Doctor of Psychology (PsyD)

The construct of wisdom has been studied over the past 30 years with the majority of the research focused on wisdom as “expert knowledge in the fundamental pragmatics of life” (Baltes & Staudinger, 2000). In the Christian tradition, wisdom can be divided into two categories: conventional and critical. Conventional wisdom bears striking similarities to the understanding of wisdom used in psychological research. In contrast, critical wisdom addresses the difficult paradoxes of life, but has not been the focus of much empirical study. Critical wisdom could be a helpful construct for clinical psychologists who hope to practice psychology from an integrative …

Zones Of Precaution, Jonathan Birch

Animal Sentience

My commentary focusses on Mikhalevich & Powell’s criticisms of the Animal Sentience Precautionary Principle. I emphasize the pragmatic nature of my rationale for proposing that, rather than extending the scope of animal welfare protection on a species-by-species basis, we should be willing to protect entire Linnaean orders on the basis of evidence from a single species.

Brain Complexity, Sentience And Welfare, Donald M. Broom

Animal Sentience

Neither sentience nor moral standing is confined to animals with large or human-like brains. Invertebrates deserve moral consideration. Definition of terms clarifies the relationship between sentience and welfare. All animals have welfare but humans give more protection to sentient animals. Humans should be less human-centred.

Invertebrate Cognition, Sentience And Biology, Georges Chapouthier

Animal Sentience

All animal species have adapted for survival and no species is superior overall. For cognitive capacities and sentience, invertebrates such as the octopus, although quite unlike vertebrates, can achieve similar performance levels. So can other invertebrates with small brains; hence they too, as sentient beings, deserve moral consideration from humans. How are we to identify these species? Only though a detailed analysis of their behavior. The decision, which is a moral judgment, depends on biological knowledge that still needs to be acquired.

Convergent Evolution Of Sentience?, Culum Brown Prof.

Animal Sentience

Mikhalevich & Powell make a compelling case that some invertebrates may be sentient and that our moral obligations in the context of welfare should hence extend to them. Although the case is similar to that made for fishes, there is one obvious difference in that examples of invertebrate sentience probably arose independently from vertebrate sentience. We have unequivocal proof that complex cognition arose multiple times over evolutionary history. Given that cognition is our best tool for indirectly quantifying sentience, it seems highly likely that this multiple polygenesis may also have occurred for sentience. In acknowledging this, we must accept that …

Attitudes Towards Mental Illness In American Evangelical Communities, Supernaturalism, And Stigmatisation, Nahanni Freeman

Faculty Publications - Doctor of Psychology (PsyD) Program

Social-cognitive variables and religious attributions regardingmental illness were examined with a homogeneous sample of 180American Evangelical Christians, using a novel tool and the MentalHealth Knowledge Scale (MAKS). In the first trial, participants wererandomly assigned to one of two Bible verse priming conditions,which made salient willpower, faith and anxiety-reduction or thesuffering Christ. Priming effects revealed that those exposed tothe willpower-faith admonishment condition showed lowerstigma on the MAKS and stronger condition recognition scores.Participants who endorsed unilateral religious causes andsolutions to mental illness also presented with less knowledgeabout mental health disorders and lower condition recognition,but the latter was unrelated to positive views regardingreligiously-informed …

Perceptions Of Police Use Of Force At The Intersection Of Race And Pregnancy, Emma Elizabeth Lee Money

Dissertations and Theses

Attention surrounding forceful policing largely focuses on men's experiences, but Black women, even when pregnant, are also harmed by police use of force. Previous research demonstrating anti-Black biases in perceptions of police use of force toward men cannot be directly applied towards women, due to unique stereotypes of Black women and mothers. How do race and pregnancy influence perceptions of police use of force against women? It was expected that pregnancy would elicit more positive responses in the current study, but only when pregnant women were also White. Benevolent sexism (BS) and social dominance orientation (SDO) were tested as moderators …
