Understanding Behavioral Health And Treatment Engagement With Former Users Of Prenatal Substances: A Strengths-Focused Mixed Methods Inquiry, Jennifer G. Benson, Peggy Maclean, Andrew Hsi, Sarah J. Erickson

Psychology ETDs

Accessible services for users of prenatal substances are lacking, and treatment engagement is poor with services that are available. Furthermore, legal consequences are often punitive, which ultimately damages the well-being of mother and child. Milagro and FOCUS are two New Mexico programs that provide comprehensive, coordinated care, including medication-assisted treatment, to former users of prenatal substances during pregnancy (in the Milagro Program) and for three years post-birth (in the FOCUS Program). This mixed methods study explored the lived experiences of women from this complex, high-risk population, using a high-engagement sample of women who utilized services at both Milagro and FOCUS. …

Seeking An Operational Definition Of Dieting: A Daily Diary Study, Elizabeth Anne Mclaughlin

Psychology ETDs

Dieting is commonly considered a weight loss technique, but research consistently shows that it does not result in weight loss. Thirty to fifty percent of women report that they are dieting at any given time, typically by responding to a single “yes/no” item asking whether they are dieting. To explain why dieting may not result in weight loss, a detailed picture was needed as to people’s behavior when they report that they are dieting, including weight loss strategies and dietary intake. Other constructs previously studied as similar to dieting were “watching what I eat” and “eating healthy.” More information was …

Mindfulness-Based Stress Reduction And Transcranial Direct Current Stimulation As An Intervention For Chronic Pain Management, Elizabeth A. Mccallion

Psychology ETDs

Chronic pain is a public health concern impacting approximately 100 million Americans; more than the rates of diabetes, coronary heart disease, stroke, and cancer combined. Mindfulness-based stress reduction (MBSR) is an effective treatment for chronic pain; however, the effects of MBSR tend to be small. A recent study suggests that tDCS in combination with a mindfulness-based intervention may enhance the learning of mindfulness skills (Witkiewitz et al., 2015). The current study used a randomized design to examine the effectiveness of active tDCS (2.0 mA) -enhanced MBSR compared to sham tDCS (0.1 mA)- enhanced MBSR. Participants were individuals diagnosed with chronic …

An Investigation Of The Neural Components And Saccade Sequences That Enable Direct Navigation Through Virtual Space, Daniel R. Barto

Psychology ETDs

Spatial navigation is a critical behavior for nearly all life forms. The ability to navigate to a destination and to remember how to return to that destination involves numerous brain processes such as perception, attention, memory, learning, proprioception, and distance estimation. The study of spatial navigation, in various organisms and on different sorts of maze-apparatuses, has revealed what is required of the brain and what is required of the environment to enable successful navigation. This dissertation adds to this vast literature by examining the physiological and behavioral components involved in human navigation in a virtual environment.

The primary aim of …

Alone In A Crowd: Perceived Social Relationships And Health Outcomes For Clergy, Christopher G. Ford

Psychology ETDs

The purpose of this study was to understand more about the relative contributions of different measures of social relationships to mental and physical health. This was done through secondary analysis of a clergy health intervention (n = 616), a population with unique professional and personal relationship characteristics. Hierarchal multiple regression was used in three steps to control for demographics, measures of perceived social relationships (e.g., social support, social engagement, social isolation, and relationship satisfaction), and whether or not clergy worked alone or with clergy colleagues. The results demonstrated that the relationship variables entered together, after controlling for demographics, were particularly …

Sex Specific Spatial Navigation And Memory Impairment In The Tgf344-Ad Rat Model Of Alzheimer’S Disease, Laura Elizabeth Berkowitz

Psychology ETDs

Spatial navigation and memory are impaired in early stages of Alzheimer’s disease (AD), and may be a defining behavioral marker of preclinical AD. Nevertheless, limitations of diagnostic criteria for prodromal AD and within animal models of AD make characterization of preclinical AD difficult. A new rat model (TgF344-AD) of AD overcomes many of these limitations, though spatial navigation and memory has not been comprehensively assessed. This study aimed to characterize. Using three paradigms of the Morris Water Maze, spatial navigation and memory were assessed in TgF344-AD (n=16) and Fischer 344 (n=12) male and female rats over three time points. TgF344-AD …

Functional Neural Connectivity Associated With Moral Processing In Healthy And Antisocial Samples, Samantha Jean Fede

Psychology ETDs

Although research finds that brain abnormalities during moral decisions underlie traits that lead to crime, understanding of these neural dynamics is limited. Here we use two samples to explore the role network engagement and components during moral processing. We used independent component analysis and functional network connectivity analysis to examine hemodynamic response during an fMRI task of moral processing. Eighty-four community and 539 incarcerated adult men and women participated; MANCOVA and machine learning algorithms were used to identify individual and group differences in both samples. We found patterns of neural engagement and connectivity consistent with proposed models of moral cognition …

Defining High Functioning Ocd (Hfocd), Samuel Meyer

Psychology ETDs

Individuals with moderate-to-severe form of OCD symptoms may display exceptional creativity and productivity. This study aimed to define the characteristics of individuals who demonstrate high life achievement/creativity and display clinically significant OC symptomatology. The main hypothesis was that OC phenomena is significantly correlated with high levels of creativity, and that individuals displaying this characteristic will demonstrate a neurocognitive profile similar to subjects with clinical OCD.

We investigated cognitive, intellectual, emotional and clinical characteristics of real-world high-achievers (HAs, n=28) as compared to “standard achievers” (SAs, n=29) by measuring OC symptoms, depressive moods, levels of creativity/flexibility, Verbal and Visual-Spatial Reasoning proficiency and …

The Modulation Of Reward To Nicotine And Ethanol By Sex And Stage Of Exposure, Kyle L. Dixon

Psychology ETDs

Tobacco and alcohol are among the most widely used and abused drugs in America, resulting in disastrous health consequences and a massive resource drain on society. Nicotine (the primary reinforcing component in tobacco) and alcohol are often used together, though there is limited research on exposure to both drugs at the same time. The present study attempted to fill this gap in knowledge by examining the reward for a cocktail of nicotine and alcohol in male and female Long-Evans rats with differing histories of drug exposure. The conditioned place preference paradigm was used to examine the effects of sex as …

Relationship Between Structure And Functional Connectivity Within The Default Mode Network, Andrei A. Vakhtin

Psychology ETDs

We proposed a novel measure of conceptualizing dynamic functional network connectivity (FNC) in the human brain using flexibility of functional connectivity (fFC), which captures the variance of functional connectivity across time. In task-free fMRI scans (N = 122), this measure was demonstrated to correspond to the underlying structural connectivity (SC) within the default mode network (DMN), while static functional connectivity (sFC) did so to a relatively low degree. As SC likely does not develop to facilitate task-free brain function, but rather to integrate information during cognitive engagement, we argue that fFC can estimate the potential functional connectivity exhibited outside of …

Modeling The Trauma-Antisociality Relationship As Mediated By World Assumptions: Associations With Gender And Drinking Outcomes, Kathryn Fokas

Psychology ETDs

Previous research has established links between traumatic experiences and externalizing pathology including substance use and antisocial behavior, but little is known about potential mechanisms linking these phenomena. This study proposed a novel conceptual model linking these phenomena via the cognitive mechanism of negative world assumptions, or beliefs about the inherent dangerousness and unpredictability of life and others. Given previous mixed findings, this study also sought to explore potential interactions between gender and these phenomena. It was hypothesized that, within a sample of adults seeking alcohol treatment, world assumptions would mediate and gender would moderate the trauma-antisociality association. It also was …

A Community Well-Being Model: Considering Audit Scores And Social Class In Non-Hispanic White And American Indian College Students, Violette Marie Cloud

Psychology ETDs

Although American Indian (AI) ethnic/racial identity and lack of social support have been linked with alcohol use problems in AI populations, little research has examined the impact of socioeconomic status, or the protective benefits of high ethnic identity with strong social connection in AI samples. This study developed and investigated a latent construct labeled community well-being (CWB) and tested it as a predictor of scores on the Alcohol Use Disorder Identification Test (AUDIT) in a sample of non-Hispanic White (NHW) and AI college students with consideration of self-reported childhood social class (birth to 18). Using structural equation modeling (SEM) this …

Social Risks As Costly Trait Signals, Ruth E. Sarafin

Psychology ETDs

Costly signaling theory posits that people will sometimes engage in seemingly irrational behavior to show off attractive qualities about themselves. These behaviors may end in or incur a cost to the actor such that only individuals who are highly fit are able to succeed at the behavior, and therefore behavior success is an honest signal of fitness. Previous research has used costly signaling to explain human physical risk taking behaviors such as rock climbing, but the current study seeks to apply them to social risk taking, such as raising one’s hand in class. Should social risk taking prove to be …

The Role Of Perceived Stress In The Relationship Between Purpose In Life And Mental Health., Anne Guzman

Psychology ETDs

Although purpose in life (PIL) has been consistently related to better mental health, there is little understanding of whether that may be explained by reducing appraisal of or reactivity to stress. The sample consisted of 546 undergraduate students who completed measures of PIL, perceived stress, and measures of both positive mental health (positive affect, life satisfaction) and negative mental health (negative affect, anxiety, depression). The hypotheses were that PIL would (1) be related to more positive and less negative mental health and (2) be related to less perceived stress, and (3) reduce the effects of perceived stress in increasing negative …

The Effects Of Comorbid Mild Traumatic Brain Injury And Alcohol Use Disorder, Brandi Seaman

Psychology ETDs

Objective: Sustaining a mild traumatic brain injury (mTBI) may influence alcohol consumption. The current study investigated the impact of self-reported mTBIs on alcohol use in a sample of individuals with alcohol use disorder (AUD) or a history of seeking treatment.

Participants and Methods: 173 individuals recruited for a neuroimaging/genetic study of alcohol abuse completed the Alcohol Use Disorders Identification Test (AUDIT) to assess consequences of consumption, and the Time Line Follow-back to assess average drinks per drinking day (DPDD). The Rivermead Concussion Scale was completed for each injury reported. The effects of the number of mTBIs (0,1, more than one) …
