Evaluating The Acute Effect Of Vaping On Food Intake, Gabrielle Maldonado
Evaluating The Acute Effect Of Vaping On Food Intake, Gabrielle Maldonado
Theses and Dissertations
Background: Weight control is a common motive for continued cigarette smoking, and weight concerns pose a barrier to quitting. These effects are driven in part by nicotine’s ability to reduce overall appetite and ultimately body weight. Electronic nicotine delivery systems (ENDS) have been marketed and used for weight control, suggesting that the use of these products potentially may share similar effects as well as barriers to quitting as observed for cigarette smoking. However, little to no controlled clinical lab evidence exists supporting ENDS use for weight control. The present study tested the influence of an ENDS on acute eating behavior …

Sleep Self-Efficacy, Loneliness, And Physical Activity: Assessing The Pathways Between Sleep Quality And Mental Health Using Structural Equation Modeling, Amber M. Fox
Theses and Dissertations
Although there is robust empirical support that poor sleep contributes to declines in mental health, explanations of this relationship remain unclear. The purpose of the present study was to examine the pattern of associations between sleep quality, sleep self-efficacy, loneliness, physical activity, and mental health among U.S. adults across the lifespan, and whether they differed by gender or age group. A structural equation model with invariance analysis was developed and examined data from 2,300 adults (Mage = 44.1, SD = 16.78) participating in the online study Investigating Sleep Longitudinally Across Normal Development (ISLAND). Sleep quality was measured by …
Defiantly Childlike: Using Aesthetic Resistance To Heal, Sarah K. Reagan
Defiantly Childlike: Using Aesthetic Resistance To Heal, Sarah K. Reagan
Theses and Dissertations
This thesis examines an alternative processing mechanism surrounding the act of healing after traumatic experiences in life. Using a methodology of iterative patterning and tool-pathing, a collection of inflatable garments and wooden mannequins analyzes defense mechanisms learned in early childhood development. This work highlights an essential body of recent scholarship that takes cuteification seriously to restore a childlike approach to mastering fear. This paper will review the definitions of cuteness and childlike humor and then describe how visual culture has implemented these components to subvert established power.

Direct And Indirect Effects Of Alcohol Craving And Demand On Obsessive And Compulsive Drinking Characteristics: The Role Of Impulsivity, James V. Turner Iv
Theses and Dissertations
This study’s goal was to test a novel model of obsessive-compulsive thoughts about drinking. Young adults completed tasks measuring potential drinking characteristics. Findings indicated demand was related to higher OCTD, a significant effect of CIC on OCTD via demand, and that the relationship was particularly strong for impulsive individuals.
Investigating Cannabinoid Type-1 Receptor (Cb1r) Positive Allosteric Modulators (Pams) In Mouse Models Of Overt Cannabimimetic Activity, Subjective Drug Effects, And Neuropathic Pain, Jayden Elmer
Theses and Dissertations
Chronic pain affects between 20 and 30 percent of the adult population in western countries and represents a wide array of specific etiologies (Berge, 2011). Neuropathic pain secondary to traumatic nerve injury, chemotherapeutic toxicity, or diseases (e.g., diabetes mellitus) is often refractory to conventional analgesics, with patients receiving less than 50% pain relief compared to placebo (Finnerup et al. 2010). The endocannabinoid system has shown potential as a therapeutic target for neuropathic pain wherein CB1 agonism via administration of exogenous agonists or pharmacological blockade of endocannabinoid catabolic enzymes exhibits efficacy in reversing allodynia in the chronic constriction injury (CCI) model …
Opioid System's Involvement In Ketamine's Antidepressant-Like Effects, Fan Zhang
Opioid System's Involvement In Ketamine's Antidepressant-Like Effects, Fan Zhang
Theses and Dissertations
Depression is one of the most debilitating disorders in the world. The currently available medications typically have a 2-4 week delay in their therapeutic effects and are ineffective for about 40% of patients. In 2000, a subanesthetic dose (0.5 mg/kg i.e.) of the dissociative anesthetic ketamine was reported to have both rapid and robust antidepressant effects in in treatment-resistant depressed patients. However, the mechanisms responsible for ketamine’s antidepressant effects remain unclear. In 2018, a clinical study reported that pretreatment with the nonselective opioid antagonist naltrexone attenuated the rapid antidepressant effect of ketamine in depressed patients. The current study investigated the …

Effects Of (R,S)-Ketamine And (2r,6r)-Hydroxynorketamine: A Preclinical Study, Remington Rice
Effects Of (R,S)-Ketamine And (2r,6r)-Hydroxynorketamine: A Preclinical Study, Remington Rice
Theses and Dissertations
In 2017, 7.1% of US adults were diagnosed with depression, and 50% of patients received medication to treat their depression. Depression can cause severe interruptions in an individual's cognitive functioning and behaviors like sleeping, eating, working, and socializing. Unfortunately, approximately 40% of patients do not respond to treatment with monoaminergic medications (e.g. Prozac) and therapeutic effects may be delayed 2-8 weeks. Due to these therapeutic shortcomings, faster acting and more efficacious treatments are needed. Recent preclinical findings indicate potential for glutamatergic drugs like (R,S)-ketamine and (2R,6R) hydroxynorketamine to produce more rapid and longer-acting therapeutic effects. The antidepressant effectiveness of (R,S)-ketamine …
Signaling Mechanism Responsible For 5-Ht2a Receptor Tolerance To Psychedelic Induced Head-Twitch Behavior In Mice, Audrey R. Mcmurtrie
Signaling Mechanism Responsible For 5-Ht2a Receptor Tolerance To Psychedelic Induced Head-Twitch Behavior In Mice, Audrey R. Mcmurtrie
Theses and Dissertations
In recent years, there has been a growing interest in psychedelic compounds stemming from their promising use as therapeutic agents and research tools that can be used to treat and study several neuropsychiatric disorders. Psychedelics have proven useful in a broad range of these diseases - they serve as models for psychosis in schizophrenia but have also had promising results in treating major depressive disorder, anxiety, and other common disorders. Decreased stigmatization surrounding psychedelics has further increased their use in research and clinical settings. In light of these trends and the promising nature of their use, a thorough understanding of …
Transcriptomic Profiling Of Postmortem Prefrontal Cortex And Nucleus Accumbens From Chronic Alcohol Abusers., Eric S. Vornholt
Transcriptomic Profiling Of Postmortem Prefrontal Cortex And Nucleus Accumbens From Chronic Alcohol Abusers., Eric S. Vornholt
Theses and Dissertations
Alcohol use disorder (AUD) is a debilitating psychiatric illness that develops from a combination of genetic and environmental factors. While it is well documented that AUD is heritable, the shift from recreational alcohol use to abuse/dependence is poorly understood. In this dissertation, using postmortem brain tissue from individuals with alcohol dependence (AD), we profiled the genome-wide expression of circular RNA (circRNA), microRNA (miRNA), and messenger RNA (mRNA) to better understand the impact of gene expression on the development of AUD. To achieve this, we performed two independent studies that explore transcriptome differences between AD cases and controls. The first of …
Impact Of Sickle Cell Disease On Executive Functioning In An Adult Population, Christina Wade
Impact Of Sickle Cell Disease On Executive Functioning In An Adult Population, Christina Wade
Theses and Dissertations
Children diagnosed with sickle cell disease (SCD) struggle with executive functions (EF); however, there is a paucity of research on neuropsychological outcomes in adults with SCD. This study aimed to examine differences in EF between adults with SCD and healthy controls. Thirty- one patients with SCD and 34 healthy controls (ages 18-45) participating in an IRB-approved Children’s Hospital Los Angeles (CHLA) study of cerebral blood flow underwent neuropsychological evaluation using the Delis–Kaplan Executive Function System (D-KEFS) Trail Making and Color Word Interference Tests and the Wechsler Adult Intelligence Scale - Fourth Edition (WAIS-IV) Digit Span subtest to assess various aspects …
Construction And Validation Of A Non-Medical Use Of Prescription Opioids Outcome Expectancies Scale Among College Students In China, Cheuk Chi Tam
Construction And Validation Of A Non-Medical Use Of Prescription Opioids Outcome Expectancies Scale Among College Students In China, Cheuk Chi Tam
Theses and Dissertations
Background:Non-medical use of prescription opioids (NMUPO) has become a clear threat to public health. Young adults (aged 18 to 25) have a high risk of NMUPO. My prior work on Chinese undergraduates indicates a high prevalence of lifetime NMUPO (49.2%). Health behavior theories propose that outcome expectancies are robust psychosocial determinants of substance use. Literature has identified the influence of outcome expectancies on alcohol and drug use. However, the role of outcome expectancies in NMUPO in China is unknown, and a scarcity of a valid measures for NMUPO outcome expectancies may be a barrier. Our previous research also found …
Examining Sleep And Family Functioning In Pediatric Craniopharyngioma Using Ecological Momentary Assessment, Nour Al Ghriwati
Examining Sleep And Family Functioning In Pediatric Craniopharyngioma Using Ecological Momentary Assessment, Nour Al Ghriwati
Theses and Dissertations
Craniopharyngiomas are among the most common brain tumors in children and are associated with greater rates of sleep problems compared to other pediatric cancers. However, research examining sleep among youth with craniopharyngioma has been limited by a reliance on retrospective reports or sleep studies. Families also play a crucial role in children’s adjustment following a pediatric cancer diagnosis, yet remarkably little is known about transactional associations between family functioning and sleep in pediatric cancer. This study examined cross-sectional and daily associations among family functioning, affect, and sleep difficulties for youth with pediatric craniopharyngioma using retrospective reports and ecological momentary assessment …
Pharmacological Assessment Of Adjuncts To Enhance Mu-Opioid Receptor Agonist Antinociception In Male Rhesus Monkeys: Does One + One = Three?, Jeremy Cornelissen
Pharmacological Assessment Of Adjuncts To Enhance Mu-Opioid Receptor Agonist Antinociception In Male Rhesus Monkeys: Does One + One = Three?, Jeremy Cornelissen
Theses and Dissertations
Mu-opioid receptor (MOR) agonists are effective agents for pain management, but are also limited by a number of undesirable effects. One approach to enhance the therapeutic effects and minimize the undesirable effects of MOR agonists may be to combine MOR agonists with an adjunct targeting a different receptor system. This targeted medical approach, known as “combination therapy”, aims to augment the desired effects of the MOR agonist (i.e. antinociception) and/or diminish the undesirable deleterious side effects of the MOR agonist. This dissertation investigated the utility of this approach in an assay of thermal nociception and schedule-controlled responding in male rhesus …

A Qualitative Study Exploring Motivation And Engagement Among Millennial Volunteers In Nonprofit Organizations, Joanne Quinones
Theses and Dissertations
This applied dissertation focused on capturing the lived experiences of Millennials and explore their motivation and engagement for volunteering in a nonprofit organization. This study illustrates the importance of civic and social engagement in our society. The Millennials have been labeled as “Genme or the me generation” (Twenge, Campbell, Hoffman, & Lance, 2010, p. 1117; Twenge, 2006, p. 1), as they have been criticized for focusing on their own self-interest. While millennials have been considered as being technologically savvy, since they grew up with the internet. The millennials, have a social interest in offering support to a cause versus an …

Cognitive Effects Of Short Duration Short Wavelength Visible Light, Sarah J. Bolton
Theses and Dissertations
This thesis research looks at the effects of short duration, high intensity, short wavelength light with the goal of determining if converting typically white colored lights in breakrooms and bathrooms to blue will cause workers who normally work in a low light environment to be more alert and productive. Sixteen participants were outfitted with Electroencephalography (and Electrooculography (EOG) equipment before being exposed to 200 lux of either 460 nm blue light or D6500 white light for 30 minutes. Afterwards, the light levels were changed to 3.5 lux of D6500 light and the participants were asked to perform six cognitive tests …
Aerobic Exercise Exposure Targeting Anxiety Sensitivity: Effects On Associated Health Behaviors In Young Adults, Autumn Lanoye
Aerobic Exercise Exposure Targeting Anxiety Sensitivity: Effects On Associated Health Behaviors In Young Adults, Autumn Lanoye
Theses and Dissertations
Anxiety sensitivity (AS) is associated with health behaviors such as low rates of physical activity, overeating, alcohol use, and poor sleep; however, interventions targeting AS via exercise-based interoceptive exposure have not assessed these as outcomes. In addition, previous studies are limited by brief follow-up periods. This study aimed to replicate previous aerobic exercise interoceptive exposures with an extended (6-week) follow-up and measurement of health behaviors.
Participants were 44 sedentary young adults with elevated AS randomized to intervention (6 20-minute sessions of moderate-intensity treadmill walking) or assessment-only control. Assessments took place at baseline, week 2 (post-treatment), week 4, and week 8 …
The Influence Of Genetic And Environmental Factors On Quit Attempt In Adolescent And Young Adult Twins, Gladys Langi
The Influence Of Genetic And Environmental Factors On Quit Attempt In Adolescent And Young Adult Twins, Gladys Langi
Theses and Dissertations
The purpose of this study was to examine the genetic and environmental influences on lifetime quit attempt in three US adolescent and young adult twin samples (N total = 6,322). The study utilized a common-contingent-causal (CCC) model to estimate these factors for lifetime quit attempts, after accounting for the factors for lifetime cigarette use and cigarettes per day. The study also examined age and sex differences, as well as the degree of relationship between these smoking phenotypes. The results demonstrated significant genetic influences for lifetime quit attempts in adolescents and young adults. No sex differences were observed for the contributions …
Motives For Participation In Triathlons Among Midlife To Older Black Women: A Mixed Method Study, Candace Brown
Motives For Participation In Triathlons Among Midlife To Older Black Women: A Mixed Method Study, Candace Brown
Theses and Dissertations
BACKGROUND: Research has established the positive link between physical activity and its impact on health among adults. Generally, as people get older, they are less likely to be active. Black women comprise 13% of the women in the US but constitute 52% of women who are inactive. Existing articles on exercise motivation among Black women have generally assessed sedentary individuals. Little research has examined the motivations to exercise among physically active Black women. METHODS: Guided by the regulators of the Self Determination Theory, the 56 item Motivations of Marathoners Scales for Triathletes (MOMS-T) was used to assess the motives of …
A Longitudinal Study Of The Motivations For The Non-Medical Use Of Prescription Drugs In A National Sample Of Young Adults, Tess K. Drazdowski
A Longitudinal Study Of The Motivations For The Non-Medical Use Of Prescription Drugs In A National Sample Of Young Adults, Tess K. Drazdowski
Theses and Dissertations
Young adults are most at-risk for the non-medical use of prescription drugs (NMUPD) and many of its associated negative consequences. Understanding this population’s motivations for use can help to inform efforts to reduce NMUPD. Past research has been limited in scope, consisting primarily of cross-sectional work with college students focusing on prescription stimulants. The current study researched how motivations for NMUPD changed over young adulthood using three waves of data from a longitudinal, nationally representative sample of 14,990 19 to 24 year olds in the Monitoring the Future study cohorts collected between 1976 to 2013. Prescription stimulants, central nervous system …
Exploring The Role Of Intersectionality On Cardiovascular Disease Risk In Sexual Minorities, Leia Harper
Exploring The Role Of Intersectionality On Cardiovascular Disease Risk In Sexual Minorities, Leia Harper
Theses and Dissertations
Background: Previous research has shown that sexual minority individuals (SM) are twice as likely to smoke, twice as likely to be overweight or obese, and less likely to be physically active than heterosexual persons; all of which place SMs at an increased risk for cardiovascular disease (CVD). While information on CVD risk by race/ethnicity and socioeconomic status is well documented, there is scant literature examining race, gender, and the potential CVD risk in SMs. The purpose of this study was to examine CVD risk in sexual minorities.
Method: The current study used data from the National Longitudinal Study of Adolescent …
Agentive Theory As Therapy: An Outcome Study, Daniel K. Judd
Agentive Theory As Therapy: An Outcome Study, Daniel K. Judd
Theses and Dissertations
The present study evaluated the efficacy of a four-week seminar which emphasized the principles of Agentive Theory. This theory, which is compatible with theories of a phenomenological/ existential perspective, was first developed by C. T. Warner, an American philosopher. Agentive Theorists/Therapists emphasize that our negative emotions, ie., depression, anger, etc. , are assertions or judgments we make and not merely feelings we are responsible for controlling or expressing. Forty-eight outpatients who sought help with personal/emotional problems from a department of behavioral medicine were assigned to either a treatment or waiting-list control Group. Following a four-week treatment phase, the treatment group …
