The Effects Of Full Spectrum Hemp Oil On Extinction Of Stress Enhanced Fear Learning In A Rodent Model Of Ptsd, Tiphanie Chanel

Psychology ETDs

There are only 2 FDA-approved treatments for Post-Traumatic Stress Disorder (PTSD) despite the overwhelming evidence of the need for safer and more effective treatments. For example, roughly 50% of treatment seeking patients with PTSD experience relief from conventional pharmaceutical medications and only one third experience full remission. The Cannabis plant is a promising novel treatment for PTSD for several reasons. The endocannabinoid system plays a role in stress, emotion, cognition, suicidal phenotypes, fear memory consolidation, retrieval and reconsolidation and extinction. Cannabidiol (CBD), one of the most widely studied phytocannabinoids found in the Cannabis plant, has both anxiolytic and antidepressant qualities. …

Wise Mind Program Evaluation, Molly Pylypciw

Psychology ETDs

Addressing adolescent mental health, especially among low-SES and racial-ethnic minority youth is imperative. This study evaluated the effectiveness and acceptability of a school-based socio-emotional learning program, called Wise Mind, delivered to a low-income, racially-ethnically diverse population. Participants (n=45 total; n = 25 intervention; n = 20 control) were ninth graders in both Special and General Education classes at a low-income racially-ethnically diverse high school in the Southwest United States. Eight one-hour sessions of Wise Mind were delivered to the intervention group over the course of eight weeks. Participants responded to questionnaires pre- and post- intervention assessing emotion regulation, mindfulness, interpersonal …

Do I Listen To You, Or Do I Listen To Me? An Individual Difference Investigation Into Advice Utilization, Danielle Nicole Sanchez-Combs

Psychology ETDs

This work addresses three fundamental questions. First, can the source of the advice (crowd or single advisor) be leveraged to enhance advice use? Second, does high skill and high metacognitive ability predict greater advice use or are these individuals also blind to the need for advice? Finally, can personality, performance, and pre-advice confidence factors be used to profile those most likely to benefit from advice? Results indicated surprisingly low advice taking rates (~25% to ~26%) from both advisors, despite the advice being 100% accurate. Advice taking was even lower when individuals were in a high-confidence state, with high-skilled …

Affective Liking Influences Reward Processing In Depression: A Computational Eeg Approach, Garima Singh

Psychology ETDs

Reinforcement learning (RL) enables agents to learn through interaction with their environment. This empowers individuals to optimize actions in complex and dynamic settings. The component of event related potential (ERP) termed as the Reward Positivity (RewP) evidently signifies a fundamental reward prediction error (RPE) associated with rewards. This characteristic implies that it represents a fundamental computational process in the assessment of RL. When a reward is particularly pleasurable or liked by an individual, it tends to elicit an amplified RewP signal, reflecting the heightened positive affect. RPE arises from disparities between anticipated and actual rewarding outcomes and is known to …

Identifying Psychosocial And Neural Correlates Associated With Future Homicide In A Sample Of Incarcerated Boys, Samantha N. Rodriguez

Psychology ETDs

Previous research has observed significant group differences regarding neuroanatomical and psychosocial variables between incarcerated boys who have and have not previously committed a homicide, resulting in successful postdictive classification (Cope et al., 2014). However, no study to date has investigated whether similar group differences characterize future homicide offenders. Following the methodology of Cope et al. (2014), the current study aimed to identify baseline neural, clinical, and environmental deficits (collected in a sample of n = 242 incarcerated juvenile offenders) associated with future homicidal behavior as adults. Results indicated that youth who went on to commit homicide as adults were characterized …

Beyond Stressors: Identifying Protective Cultural Factors And Coping Strategies For Mental Health Symptoms Among Aging Latino/Hispanic Immigrants, Juan M. Pena

Psychology ETDs

Within the next decade, Latino immigrants will constitute the largest middle-aged and older immigrant group living in the U.S. This cross-sectional study investigated traumatic stressors, acculturative stress and perceived structural injustices and their associations with mental health symptoms. This study also examined the linkages between cultural factors, social support, and coping strategies and mental health outcomes. Eighty Latino/Hispanic immigrants who were 45 years of age or older completed a series of questionnaires and optional open-ended questions. A greater exposure to traumatic events, higher acculturative stress, and perceived injustices were associated with greater psychological distress and symptoms of anxiety, depression, and …

Examining The Measurement Invariance Of The Revised Sociosexual Orientation Inventory Among Hispanic And Non-Hispanic White College Women, Christina Nicole Gillezeau

Psychology ETDs

I examined whether the Revised Sociosexual Orientation Inventory (SOI-R) was invariant between Hispanic/Latina and Non-Hispanic White (NHW) undergraduate women. I performed confirmatory factor analysis to assess model fit and used increasingly restrictive models to test invariance. I included 208 Hispanic/Latina women and 190 NHW women. The CFI and RMSEA model fit statistics (CFI=0.98, RMSEA=0.06 (90% confidence interval=0.04-0.08, p-value=0.16) showed that the model fit well. I constrained factor loadings to be equal in both groups to test metric invariance. I observed non-significant differences in model fit (deltaX² (9)=88.67, p>0.95, deltaCFI=0.003, deltaRMSEA=-0.011). I also constrained intercepts to be equal to …

Electrophysiological Signatures Of Error Commission And Adjustment, Mark Lavelle

Psychology ETDs

Errors inhibit attainment of our goals. Behavioral and neural adjustments following errors are often framed as independent aspects of decision-making termed threshold (or response caution) and drift rate (or evidence accumulation). We replicated and extended the association of single-trial threshold with frontal midline theta power from the previous trial, as measured from EEG in 21 participants completing a flankers task. Surprisingly, theta power also predicted next trial drift rate. Variation in brightness of the stimuli was associated with drift rate and various EEG and time-frequency features, including posterior alpha/beta power. Posterior alpha/beta power also correlated with drift rate and significantly …

An Examination Of The Associations Between Covid-19 Vaccine Hesitancy, Trust In Media, And Trust In Science And Scientists, Jegason Phosphorus Diviant

Psychology ETDs

Recent evidence suggests corroded trust in scientific institutions, but particularly among political conservatives. The current investigation examined the potential role of trust in conservative media sources by capturing associations between trust in politically-biased media sources, trust in science and scientists, and COVID-19 vaccine hesitancy. A total of 1,117 participants completed an online cross-sectional self-report study. Results revealed that: (1) the less trust respondents had in science and scientists, the greater their overall COVID-19 vaccine hesitancy (and perceived risks and fears of COVID-19 vaccines); and (2) the more respondents trusted conservative-leaning news media sources, the greater their overall COVID-19 vaccine hesitancy …

Feasibility And Acceptability Of An Online Empathy Skills Training For Substance Use Providers, Emily L. Starratt

Psychology ETDs

The ability to train counselors to convey empathy is critical, given the importance of therapist empathic skill level in substance use disorder treatment outcomes (Moyers & Miller, 2013). To date, no studies have examined the efficacy of an online empathy skills training for clinicians, where competency is evaluated using objectively rated standardized client sessions. This study evaluated the acceptability, feasibility, and fit of an online empathy skills training for substance use disorder providers. METHOD: Therapist empathy was measured pre-post training using standardized client actor interviews and evaluated with a global rating yielded by the Motivational Interviewing Treatment Integrity Code 4.2 …

Effects Of Childhood Health And Adversity On Women’S Estrous And Extended Sexuality In Romantic Relationships, Tran Dinh

Psychology ETDs

Variations in childhood conditions may favor different strategies of investment in pair-bonds and reproduction. The current study followed 213 romantically-involved women up to four times across the ovulatory cycle. Analyses find that childhood health and adversity moderate hormone-dependent changes in women’s sexual interests, oxytocin responses, and mate preferences. In light of proposed paternity assurance functions of extended (non-conceptive) sexuality, results suggest women with poorer, compared to better, childhood conditions prioritize bond formation but invest less in maintaining or bolstering partner investment. The estrous (conceptive) sexuality of women with poor childhood health may reflect greater investments in current reproduction, even when …

Validation Of The Addictions Neuroclinical Assessment Among Diverse Individuals With Alcohol Use Disorder, Elena R. Stein

Psychology ETDs

Individuals with alcohol use disorder (AUD) are heterogeneous in terms of etiology, maintenance, symptoms, and recovery, yet current diagnostic categories fail to adequately capture this heterogeneity. Corresponding to the neurobiological addiction cycle, the Alcohol and Addictions Research Domain Criteria proposes a framework of three core domains disrupted in AUD: negative emotionality, incentive salience, and executive function. The Addictions Neuroclinical Assessment (ANA) is a hypothesized multimodal assessment battery of these three domains, which may better characterize AUD heterogeneity. The current study validated the ANA in a sample of drinkers (N=245) who were diverse with respect to ethnicity and alcohol treatment-seeking status. …

How Children Make Sense Of Fear Of The Dark: A Qualitative Study Of Russian Preschoolers, Maria Mccready

Psychology ETDs

Children’s fear of the dark—as well as its more extreme manifestation in the form of nyctophobia—is a major problem for many families with smaller children. Different treatments exist for nyctophobia, but no consensus has yet emerged on why these treatments work or on what facets of the treatments are more effective than others. Several methodologies and assessments allow for the quantitative measurement of children’s “normative,” or typically developing, fear of the dark, but most were created and conducted from an adult perspective. How children themselves explain what makes darkness scary remains largely unknown, in large part because children have traditionally …

The Reward Positivity As An Additive And Temporally Independent Event-Related Potential Feature, Trevor C J Jackson

Psychology ETDs

The reward positivity (RewP) is a feedback-related event-related potential elicited in response to reward with two distinct defining features. First, it reflects an axiomatic reward prediction error signal. Second, it is spectrally represented within the delta band. We propose a third defining feature, namely that it is an additive and temporally independent event-related potential feature. Across five datasets and ten studies, this dissertation tested three major hypotheses. First, we show that stimulus modality (e.g. visual and auditory stimuli) and parametric delays can shift the RewP in time, which empirically indicates an additive and temporally independent feature. Second, we provide some …

Impact Of Emotional Processing On Working Memory In Preadolescents With High Autistic And Anxiety Traits, Teagan Mullins

Psychology ETDs

Adolescence is an important neurodevelopmental period that confers both opportunity for positive change, and a risk for emerging psychopathology. In particular, anxiety disorders and autism spectrum disorder (ASD) both cause significant challenges during adolescence that impact individuals throughout their lifespan. Notably, functional impacts of anxiety and ASD are not limited to those who meet diagnostic criteria, and can be present at sub-clinical levels. However, despite high rates of co-morbidity of ASD and anxiety symptomology, the degree to which the neural bases of anxiety are similar or qualitatively different in individuals with and without autistic traits is unknown. One candidate neurobehavioral …

Mental Distress Among Adults With Serious Mental Illness In A Criminal Legal Setting: A Secondary Data Analysis Of The Mcarthur Mental Health Court Study Data, Violette Cloud

Psychology ETDs

Chronic criminal legal system (CLS) involvement among individuals with serious mental illness (SMI) is of growing concern. Mental health courts (MHCs) are a known diversion strategy currently used by the CLS to address this problem. MHCs are seen as an effective method for linking individuals with SMI to needed treatment, removing them from a detention setting, and subsequently reducing recidivism. However, less is known about the impact of MHC enrollment on mental health related outcomes (mental distress). Using the McArthur Mental Health Court Study data, this study aimed to inspect the impact of MHC participation, legal coercion, and treatment motivation …

Assessing Verbal Memory Task Performance And Intractable Epilepsy: The Associations Among Hippocampal Volume Ratio, Seizure Demographic Factors And Memory Indices, Alexis Gabrielle Burks

Psychology ETDs

Epilepsy affects 3.4 million people in the United States and may affect their memory performance. This study investigated the relationships between memory performance, hippocampal volume ratio, and demographic factors in adults with intractable epilepsy in standardized memory tasks and an experimental memory task designed to be repeated daily. Participants underwent electrode implantation surgery and completed comprehensive neuropsychological assessments prior to surgery including an experimental memory task during their stay in the hospital. Correlation, ANOVA, and regression analyses were completed. The standardized memory tasks and the experimental memory task were significantly correlated. Hippocampal volume ratio was not significantly correlated to memory …

Examining The Relationship Between Anxiety And Depression Symptoms, Protective Behavioral Strategies And Opioid Use Outcomes, Melissa Rose Hatch

Psychology ETDs

Protective behavioral strategies (PBS), behaviors individuals use to reduce negative consequences of substance use, have been shown to mediate and moderate the relationship between mental health and substance use outcomes. The present study aimed to examine the relationships between anxiety and depression symptoms and opioid PBS on risky opioid use and opioid-related consequences. Participants in this secondary data analysis were non-treatment seeking individuals who reported past-month opioid use (n=257). Structural equation modeling was used to examine 1) PBS as a mediator of the relationship between anxiety/depression symptoms and opioid use outcomes, and 2) anxiety/depression symptoms as a moderator …

Trait Sadism In Bdsm Practitioners And Non-Practitioners, Marley Russell

Psychology ETDs

Sadism is an elusive construct within psychology. Multiple types are studied without clear psychometric or theoretical distinctions, and operationalizations of these respective sub-constructs lack validity. This study explores the empirical distinction between two sadism types: consensual sexual sadism (i.e. in the context of BDSM) and trait sadism. Trait sadism is widely synonymized with “everyday sadism”, but here conceptualized as a higher-order construct encompassing both everyday and a novel “prosocial sadism”. I develop and pilot the BDSM Identities and Behaviors (BIB) checklist in a sample of BDSM practitioners. I then compare those practitioners to non-practitioners on trait sadism and dark triad …

Non-Abstinent Recovery In Mindfulness-Based Relapse Prevention: Exploring Mechanisms Of Change And Social Moderators, David I.K Moniz-Lewis

Psychology ETDs

Recovery from substance use disorder (SUD) is heterogeneous by nature. Yet, over the last 50 years, substance use treatment providers and researchers have often defined success as sustained abstinence from substances. An often overlooked but equally valid pathway to recovery for persons with SUD is non-abstinent recovery. However, the majority of the literature on non-abstinent recovery exists for individuals with alcohol use disorder (AUD) with little empirical inquiry into non-abstinent recovery for other types of SUD. Additionally, there is also no known literature, to date, that explores the mechanisms that lead to non-abstinent recovery for individuals who have engaged in …

Humor Styles, Psychological Well-Being, And Distress: Examining The Importance Of Resilience And Hope, Naila V. Decruz-Dixon

Psychology ETDs

The current research study investigated the relationship between different adaptive and maladaptive styles of humor, psychological well-being, and distress measures. The sample for this cross-sectional analysis included 237 undergraduate students at the University of New Mexico. Zero-order correlation analyses of all the study variables revealed that adaptive humor styles were associated with greater psychological well-being and lower psychological distress symptoms while maladaptive humor styles were generally related to lower well-being and greater distress symptoms. All four humor styles were significantly associated with hope, while only affiliative and self-defeating humor were associated with resilience. Mediation analyses revealed that resilience was a …

Precision Medicine Approaches To Alcohol Use Disorder For American Indians: Assessment And Phenotypic Differentiation Of Reward And Relief Drinking, Hanna M. Hebden

Psychology ETDs

American Indian (AI) communities endorse high rates of abstinence from alcohol and substance use, yet experience disparate rates of alcohol and substance-related consequences. Alcohol and substance use is conceptualized as interwoven with unique AI contextual factors, which are often not incorporated into examination of related constructs. Current knowledge gaps exist in study of precision medicine approaches to treatment for reward and relief drinking in AI. This study aimed to understand reward and relief substance use phenotypes in AI. We described a contextually-informed model of relief assessment and to compare this assessment to the original reward and relief models using latent …

Effects Of A Psychological Stressor On Methamphetamine Seeking In Rats., Kayla B. Cox

Psychology ETDs

Although methamphetamine abuse and fatality rates are on the rise in the United States, there are currently no FDA approved drugs to treat methamphetamine use disorder (MUD). To better understand factors contributing to addiction, researchers have designed various rodent models of stress including the use of footshock, social defeat and maternal separation, however, these models involve physical or early life stress exposure and thus are less translatable to human psychological stress. The present study implemented predatory odors as a model of psychological stress and examined whether chronic exposure to these stressors enhanced subsequent vulnerability to a subthreshold dose of methamphetamine. …

Source Estimation Of The Reward Positivity And Related Resting State Network Activity In Major Depressive Disorder, Christopher J.H. Pirrung

Psychology ETDs

Anhedonia is a complex symptom of Major Depressive Disorder (MDD) that presents itself through multiple behavioral phenotypes of diminished reward processing. In order to better understand this deficit, we aim to look at a marker of reward that is sensitive to information content and valence, the Reward Positivity (RewP). The source of this signal is, however, up for debate. This study used concurrent EEG and MEG to establish the source of the RewP as a distributed network involving ventromedial prefrontal cortex (vmPFC), anterior midcingulate cortex (aMCC), and insulae. Additionally, only vmPFC showed a deficit in MDD. fMRI resting state functional …

Traumatic Brain Injury And Psychopathy In Incarcerated Men And Women, Tessa Cappelle

Psychology ETDs

Traumatic brain injury (TBI) is one of the most suffered injuries with detrimental effects on the individual’s health, personality, and behavior. Overlap exists between TBI sequelae and symptoms of psychopathy. Both conditions are especially prevalent in incarcerated populations which makes studying their interrelation critical. Two studies examined the relationship between history of TBI (TBI+ vs. TBI-) and psychopathy (via the Hare Psychopathy Checklist-Revised; PCL-R) in adult incarcerated men and women at correctional facilities in New Mexico and Wisconsin. Study 1 included 342 women, study 2 included 1049 men. Measurement invariance was evident for TBI+ and TBI- for both studies. TBI+ …

Exploring The Role Of Dieting Style In Nutritional And Psychological Health Among College Women, Hayley L. Vanderjagt

Psychology ETDs

The current study aimed to profile styles of eating among dieting and non-dieting college-aged women, and to explore the extent to which dieting attitudes were associated with both nutritionally healthy eating and psychological well-being. A latent profile analysis was conducted using indicators of self-reported intuitive eating, binge eating, and two psychometric measures of dietary restraint; various measures of eating restraint were utilized to potentially capture distinct characteristics of dieting, such as self-discipline and disinhibition (Polivy et al., 2020; Stice et al., 2010). Four distinct probabilistic profiles emerged, indicating that individuals within the study population could be meaningfully categorized as Intuitive …

An Application Of Tajfel’S Social Identity Theory To Understand Gamer As A Social Identity Among Saudi College-Level Students, Mohammad M. Assiri

Language, Literacy, and Sociocultural Studies ETDs

Understanding the social identity construction of Saudi college-level students who self-identify as gamers in Saudi Arabia is essential when designing a student-centered education. Although support exists within the literature for exploring what it means to be a gamer from the perspective of gamers, a review of the literature revealed a gap in this regard in the context of Saudi Arabia. Therefore, this grounded theory study explored self-identification as a gamer in Saudi Arabia using Tajfel's (1981) three tenets of self-identification with a group. A social identity framework was used to understand the characteristics of Saudi gamers, their positive or negative …

Development Of A Measure Of Physical Distancing: The O'Sickey Distancing Test, Anthony J. O'Sickey

Psychology ETDs

Introduction: Covid-19 has swept the globe and has disproportionately affected the United States with over 600,000 deaths in just over one year. The Centers for Disease Control recommendations for reducing the spread of Covid-19 have focused on physical distancing (PD), the practice of maintaining a distance greater than 6 feet from individuals not in the same household. When employed, this health behavior has been found to reduce the incidence of Covid-19. A review of the measurement literature evaluating PD indicates that PD has been measured at the community level via GPS, using proxy measures of the behavior, or as a …

Exploring Components For A Family-Focused Intervention For Families With A Child Diagnosed With Cancer And Other Chronic Illnesses, Nicole Kubinec

Psychology ETDs

Chronic illnesses are often life-long and affect academic performance, social development, psychological well-being, and family functioning. The broad effects of childhood chronic illnesses are often assessed using measures of child health-related quality of life (HRQL). Parent factors (parental distress, perceptions of child vulnerability, overprotection) and family factors (maintaining rituals, open communication, positive coping) have been associated with changes in child HRQL. This study sought to discover how parent and family factors were associated with child HRQL, and how such factors were perceived by families for inclusion in future interventions. Results demonstrated that parental perceptions of child vulnerability were associated with …
