Electronic Cigarette User Plasma Nicotine Concentration And Puff Topography: Influence Of Liquid Nicotine Concentration And User Experience, Marzena M. Hiler

Theses and Dissertations

Electronic cigarettes (ECIGs) aerosolize an often nicotine-containing solution for user inhalation. ECIG nicotine delivery may depend on liquid nicotine concentration and user puffing behavior (topography). This study examined the relationship among liquid nicotine concentration, puff topography, and plasma nicotine concentration. Thirty-three ECIG-experienced and 31 ECIG-naïve individuals completed four laboratory sessions that differed by ECIG liquid nicotine concentration (0, 8, 18, or 36 mg/ml). A 3.3 volt “eGo” ECIG battery attached to a 1.5 Ohm dual coil “cartomizer” filled with 1 ml of 70% propylene glycol/30% vegetable glycerin nicotine liquid was used in two ECIG-bouts (10 puffs; 30 s IPI). Plasma …

Family Dynamics And Personal Strengths Among Dementia Caregivers In Argentina, Aaliah G. Elnasseh, Michael A. Trujillo, Silvina Victoria Peralta, Miriam E. Stolfi, Eliana Morelli, Paul B. Perrin, Juan Carlos Arango-Lasprilla

Psychology Publications

This study examined whether healthier family dynamics were associated with higher personal strengths of resilience, sense of coherence, and optimism among dementia caregivers in Argentina. Caregivers are usually required to assist individuals with dementia, and family members have typically fulfilled that role. Personal strengths such as resilience, sense of coherence, and optimism have been shown to protect caregivers from some of the negative experiences of providing care, though the family-related variables associated with these personal strengths are largely unknown. Hierarchical multiple regressions investigated the extent to which family dynamics variables are associated with each of the caregiver personal strengths after …

Personality Traits In College Students And Caregiving For A Relative With A Chronic Health Condition, Michael A. Trujillo, Paul B. Perrin, Aaliah Elnasseh, Bradford S. Pierce, Melody Mickens

Psychology Publications

The purpose of this study was to investigate among college students the relationship between personality traits and willingness to care for a relative with a chronic health condition. 329 undergraduate students completed an online questionnaire. Hierarchical multiple regressions found that after controlling for demographics personality traits explained 10% of the variance in willingness to provide emotional care, 7% in instrumental care, and 7% in nursing care. Within these models, greater empathy was uniquely associated with willingness to provide emotional, instrumental, and nursing care for a family member in the future. Similarly, participants with high agreeableness were more willing to provide …

Considerations In The Provision Of Mental Health Services Toward Arabs, Dalia Khoury

Theses and Dissertations

Existing evidence suggests that disparities exist in the use of mental health services by Arabs in the U.S. While there are likely many factors that contribute, lack of cultural competence of mental health providers is one potentially important barrier for mental health service use among racial/ethnic minorities, including Arabs. The primary purpose of this study was to identify and examine factors related to the development and existence of cultural competence toward Arabs. Variables measuring demographics, professional characteristics, familiarity with Arabs, prior experience and knowledge of Arabs, and readiness for change were tested with a randomly selected sample of mental health …

Abating Prejudice With Presence: Dispositional Mindfulness Increases Interracial Helping Behavior, Justin Tubbs, Daniel R. Berry, Kirk Warren Brown

Undergraduate Research Posters

Helping behavior is less frequently shown toward members of social out-groups (Cikra, Bruneau, & Saxe, 2011). Race defines a common source of social division in America and other countries, and although most condemn racial discrimination, helping is undermined in interracial interactions (Saucier, Miller, & Doucet, 2005). Recent theory suggests that mindfulness, a receptive attention to one’s present experience, can attenuate the conceptual boundaries that typically separate and distance oneself from others (Trautwein, Schmidt, & Naranjo, 2014). We designed an experiment to examine whether dispositional mindfulness would be associated with increased helping behavior in interracial contexts. Self-identifying White participants ( …

Body Image Perception: Adolescent Boys And Avatar Depiction In Video Games, Usha Raman

Auctus: The Journal of Undergraduate Research and Creative Scholarship

Research on mass media’s impact on body image has mostly been focused on females thus far. Of the little research that has been done on male body image, most of it has been focused on adult males, and therefore the effect of mass media on adolescent boys’ body image is still a relatively primitive field of knowledge. Through comparing the exposure of adolescent boys to muscular avatars in popular video games, a source of mass media that a majority of adolescent boys are exposed to, and relating it to research done on the effects of frequent ideal image exposure through …

On Workaholism: Do Parental Work Behaviors Predict The Work Behaviors Of Undergraduates?, Jesse A. Wingate

Theses and Dissertations

This cross-sectional study examined the associations among perceived parental behavior and personality on work behaviors of undergraduate students from a large Southeastern university. Past research suggests that children who perceive their parents to be workaholics are more likely to exhibit workaholic behavior themselves (Chamberlin & Zhang, 2009). Moreover, personality factors including conscientiousness and neuroticism, have been categorized as antecedents of workaholic behavior in previous studies (Andreassen, Hetland, & Pallesen, 2010; Aziz & Tronzo, 2011; Burke, Matthiesen, & Pallesen, 2006). Students (N = 209) completed questionnaires assessing Big Five personality factors, dispositional optimism, and perceptions of parental work drive, parental …

Rage And Social Media: The Effect Of Social Media On Perceptions Of Racism, Stress Appraisal, And Anger Expression Among Young African American Adults, Morgan Maxwell

Theses and Dissertations

Recently, social media has become a sociopolitical hotbed for discussions of racism. However, no extant studies have questioned if social media use increases how often African Americans vicariously and/or personally experience discrimination in America. The current study sought to answer this question. By examining the relationships between social media use, general stress, race-related stress, and anger expression, and the mediating role of perceived racism, this study explored if frequent social media use influences young African American adults’: a) perceptions of racism, b) experiences with general and race-related stress, and/or c) expressions of anger. The current study conducted an online survey …

The Role Of N-Acetyl-L-Cysteine (Nac) As An Adjuvant To Opioid Treatment In Patients With Inadequately Controlled Chronic Neuropathic Pain, Thomas B. Moore

Theses and Dissertations

Introduction. While opioid medications are commonly prescribed for management of neuropathic pain (NP), long-term use has been associated with increased risk for overdose, drug interactions and addiction. New strategies are necessary to better manage chronic pain, thereby reducing need for opioid medications and their associated adverse consequences. N-acetyl-L-cysteine (NAC), an over-the-counter supplement, has shown promise in the treatment of psychiatric and addictive disorders. In addition, NAC has shown promise for reducing physiological signs of NP in laboratory rat models, prompting this study.

Purpose. The present study was an open-label clinical trial of NAC as an adjuvant to opioid treatment for …

Positivity Ratio: Predicting Sleep Outcomes Across The Adult Lifespan, Janna L. Imel

Theses and Dissertations

Although sleep has been linked to changes in positive and negative affect across the lifespan, the prediction of sleep from affect has not been explored completely. As such, the main objective of this study was to examine the association between affect and sleep across the adult lifespan, using a novel gauge of affect, the positivity ratio. Both subjective and objective assessments of sleep were used in analyses. This study was an archival analysis of data collected as a part of the Midlife in the United States Study (MIDUS-II), with participants ranging from 34 to 83 years of age. Results revealed …

Urban Stressors And Child Asthma: An Examination Of Child And Caregiver Models, Gillian G. Leibach

Theses and Dissertations

The purpose of the present study was to examine how low-income, racial and ethnic minority, urban families experience and manage their child’s asthma. The rationale for this study stems from existing literature on asthma disparities and documented predictors of increased asthma morbidity and mortality. In particular, this study considered how specific types of stress may disproportionately impact low-income, racial and ethnic minority, urban families that have a child with asthma. This study aimed to determine associations between urban stressors (stressful life events, perceived discrimination, subjective socioeconomic status) and child asthma outcomes (emergency department visits, school days missed, asthma control), and …

An Examination Of The Technical And Relational Hypotheses Of Motivational Interviewing In A Sample Of African American Adolescent Girls Seeking Obesity Treatment, Rachel L. Boutte

Theses and Dissertations

Adolescent obesity has increased exponentially over the past three decades in the United States. In response, behavioral interventions have been developed and implemented to address this epidemic; however, treatment adherence is often suboptimal. Motivational interviewing (MI) is a directive, person centered approach to reducing patient ambivalence about change, which has been shown to increase engagement in obesity interventions. The current study investigated the underlying process of MI by exploring two different, but related pathways that explain how change happens (e.g., the technical and relational hypotheses) in the context of a multidisciplinary obesity intervention with African American adolescent girls (N …

Acute And Chronic Effects Of Inhalants In Intracranial Self-Stimulation, Matthew Tracy

Theses and Dissertations

Inhalants are a loosely defined diverse group of volatile substances which people abuse. Despite widespread misuse of inhalants, there are limited preclinical methods available to study the reinforcement-like properties of inhalants. One procedure which has demonstrated substantial promise as a tool to investigate inhalant pharmacology is the intracranial self-stimulation (ICSS) procedure. ICSS utilizes pulses of electrical stimulation to the mesolimbic reward pathway to serve as a temporally defined and controlled operant reinforcer with a highly adjustable efficacy. The first aim of the project was to characterize the effects of commonly abused inhalants: including toluene, trichloroethane, nitrous oxide, isoflurane and R134a …

Exploring The Outcomes Of Rehabilitative Care For Veterans And Service Members Treated For A Disorder Of Consciousness In The Vha Emerging Conciousness Program, Janette A. Hamilton

Theses and Dissertations

Over the past several years, there has been an influx in patients being treated for polytraumatic injuries within the Veterans Health Administration (VHA), largely due to the wars in Afghanistan and Iraq, but also due to advances in life sustaining medical interventions. The polytrauma population includes veterans who have sustained a severe traumatic or non-traumatic brain injury, and a significant loss in cognitive and physical functioning, referred to as a disorder of consciousness. The purpose of the current study was to explore factors related to successful emergence from a disorder of consciousness, using a sample of veterans who were treated …

Development Of A Two-Factor Self-Forgiveness Scale, Brandon J. Griffin

Theses and Dissertations

Notwithstanding progress made in description, prediction, and manipulation of self-forgiveness, the extant literature continues to be wrought with theoretical and empirical quandaries. In the current dissertation, I conceptualize self-forgiveness within the framework of Social Cognitive Theory and develop a two-factor scale to assess distinct decisional and emotional aspects of self-forgiveness among perpetrators of interpersonal transgressions. In Study One, I test the hypothesized two-factor structure in a new measure of state self-forgiveness and provide preliminary evidence supporting construct validity via associations of that measure with perceived responsibility, guilt, and shame. In Study Two, I replicate the factor structure and provide preliminary …

Internal And External Validity Of Sluggish Cognitive Tempo In Young Adolescents With Adhd, Zoe Smith

Theses and Dissertations

Adolescents with Sluggish Cognitive Tempo (SCT) show symptoms of slowness, mental confusion, excessive daydreaming, low motivation, and drowsiness/sleepiness. Although many symptoms of SCT reflect internalizing states, no study has evaluated the utility of self-report of SCT in an ADHD sample. Further, it remains unclear whether SCT is best conceptualized as a unidimensional or multidimensional construct. In a sample of 262 adolescents comprehensively diagnosed with ADHD, the present study evaluated the dimensionality of a SCT scale and compared CFA and bifactor model fits for parent- and self-report versions. Analyses revealed the three-factor bifactor model to be the best fitting model. In …

The Influence Of Client-, Family-, And Therapist-Level Pretreatment Characteristics On Therapist Delivery Of Youth Psychotherapy Treatments, Adriana Rodriguez

Theses and Dissertations

The purpose of this exploratory study was to examine the extent to which pretreatment characteristics influence therapist treatment adherence by using data sampled from a randomized effectiveness trial and an efficacy study. Research suggests that youth-, family-, and therapist-level pretreatment characteristics influence therapist behavior; however, this area is underdeveloped as most studies have focused on externalizing problem areas, family-based approaches, and the use of parent or therapist report to assess for therapist adherence. To date, no research has examined this question with anxiety as the target problem, individual-focused CBT, and with observational therapist adherence data. An observational coding measure, Cognitive-Behavioral …

Representativeness Of Patients Enrolled In A Primary Care Clinical Trial For Substance Use Disorders, Sydney S. Kelpin

Theses and Dissertations

Understanding the characteristics of research participants is crucial to ensuring sample representativeness and generalizability of findings to broader patient groups with substance use disorders. Using anonymous computer-administered health survey data, the present study had a unique opportunity to compare patients who chose to participate in an RCT for heavy/problem drinking or drug use (N=713; consenters) with those that chose not to participate (N=625; non-consenters). The sample was 40% male, 76% African American, and had a mean age of 45.2 years. Using multivariate regression, the most parsimonious model found older age, unemployment, prescription misuse, positive screen for drug problems (CAGE), having …

Evaluating A Brief Web-Based Prevention Intervention For Risky Alcohol Use Among College Students, Zoe Neale

Theses and Dissertations

The purpose of this study was to evaluate a brief, web-based alcohol prevention intervention program as a universal approach to addressing the range of alcohol behaviors present on college campuses. The sample of freshman college students recruited from Spit for Science (Dick et al., 2014) included 153 intervention participants, and 151 control participants matched on demographics and baseline alcohol variables. Hierarchical multiple regression, logistic regression, and moderated multiple regression were used to compare intervention and control participants on post-intervention alcohol variables. Treatment predicted lower alcohol use disorder (AUD) symptoms, particularly among baseline drinkers. For non-drinkers, the intervention was associated with …

Reciprocal Relations Between Traumatic Stress And Physical Aggression During Middle School, Erin L. Thompson

Theses and Dissertations

There is convincing evidence that demonstrates traumatic stress and aggressive behavior are highly related among adolescents. The evidence is less clear regarding the direction of this relation. The purpose of this study was to examine the reciprocal longitudinal relations between physical aggression and traumatic stress among a predominantly African American sample of middle school students. Support was found for traumatic stress predicting increased levels of physical aggression across the winter to the spring of the sixth grade for boys and across all waves from the fall of the seventh grade to the fall of the eighth grade for both boys …

Gender And Sexual Health: Applying Gender Role Theory To Men And Women’S Intention To Engage In Sexual Health Information Seeking Behaviors, Ariella R. Tabaac

Theses and Dissertations

The purpose of the present study is to examine the pathways between gender and behavioral intention to engage in sexual HISB through application of the Theory of Planned Behavior (TPB). It was found that feminine and masculine gender role stress differentially influence perceived behavioral control and behavioral attitudes, and that intention to engage in HISB was higher among women than men. Attitudes and PBC significantly predicted behavioral intention in this model. Further, women in the sample were more likely to search for sexual health information, with online sources being the most frequently reported resource. Additionally, past HISB was a significant …

From Intra- To Inter-Personal: Effects Of Mindfulness Training On Emotion Regulation In Social Contexts, Jordan T. Quaglia

Theses and Dissertations

The social and emotional lives of people are highly interdependent. Incipient evidence suggests that attention may also play an essential role in determining one’s social and emotional well-being. Mindfulness, as a manner of attending, entails greater moment-to-moment awareness to internal and external events, and is thought to have both intra- and inter-personal benefits. Here a study of mindfulness training (MT) examined whether training mindful attention would improve emotion regulation in social contexts as indexed by neural, behavioral, and experience sampling measures. More specifically, 60 participants in romantic relationships were randomly assigned to either four brief (20 min.) MT sessions or …

Behavioral Phenotyping Of Vmat1 Knockout Mice: Relevance To Neuropsychiatric Disorders, Kevin A. Webster Ph.D.

Theses and Dissertations

Schizophrenia is a debilitating mental disorder that causes a large economic burden and is prevalent across all cultures and countries around the world. Although both environmental factors and genetics are known to play an important role in the etiology of schizophrenia, the exact role of genetics and its interaction with environmental factors in an individual’s predisposition to develop schizophrenia is poorly understood. Schizophrenia is characterized by symptoms that include positive symptoms (e.g. delusions, hallucinations, disorganized thinking and speech), negative symptoms (e.g. avolition, anhedonia, depressive-like behavior), and cognitive dysfunctions (e.g. executive functioning deficits in learning and memory, attention, and vigilance). Genomic …

Identifying Profiles Of Resilience Among A High-Risk Adolescent Population, Anna W. Wright

Theses and Dissertations

The purpose of the present study was to determine whether distinct patterns of adolescent adjustment existed when four domains of functioning were considered. The study included a sample of 299 high-risk urban adolescents, predominantly African American, ages 9-16 and their maternal caregivers. Cluster analysis was used to identify patterns of adjustment. Logistic regression analyses were used to explore whether variations in levels of five theoretically and empirically supported protective factors predicted cluster membership. A four-cluster model was determined to best fit the data. Higher rates of goal directedness and anger regulation coping predicted membership within the highest functioning cluster over …

Loneliness, Cynical Hostility, And Cognitive Decline In Americans Above Age 50, Sarah C. Griffin

Theses and Dissertations

Background. Research identifies isolation (being alone) as a risk factor for cognitive decline— yet it is possible that subjective dimensions of isolation are more critical. Potential risk factors are loneliness (the distress stemming from feeling alone) and cynical hostility (an attitude of distrust and cynicism). The present study examined the relationship between these factors and cognitive functioning and decline.

Methods. Data came from the Health and Retirement Study, a nationally representative longitudinal study of US adults over 50. Loneliness was measured using the Hughes Loneliness Scale; cynical hostility was measured using items from the Cook-Medley Hostility Inventory. Cognitive functioning was …

Longitudinal Relations Between Parental And Peer Support For Violent And Nonviolent Responses To Conflict And Early Adolescent Dating Aggression, Rachel C. Garthe

Theses and Dissertations

High prevalence and the negative legal, health, and psychological consequences of adolescent dating aggression underscore the need to identify risk and protective processes associated with this type of aggression. Studying dating aggression in early adolescence is important, as this is the developmental time frame when most youth are establishing attitudes, beliefs, and norms for dating behaviors. The current study investigated longitudinal associations between perceived parental and peer support for violent and nonviolent responses to conflict and dating aggression perpetration among middle school students. Participants included 1,399 adolescents (52% female) in the sixth (n = 466), seventh (n = …

The Transition From The Psychical To The Psychological: An Examination Of William James’ Influence On Henry James’ “The Turn Of The Screw”, Harry A. Jones Iv

Theses and Dissertations

This thesis will show that, in its original form, “The Turn of the Screw” acted as a monument to the intellectual unity shared between Henry James and his brother William. Through evaluating James’ biography, memoirs, and letters with William, this thesis will illustrate the subtle collaborative inspirations that initially helped James write the first twelve-part serial edition of “The Turn of the Screw” for Collier’s Weekly, which ran from January 27, 1898 until April 16, 1898. I will also demonstrate the effect of William’s philosophy and his death on the revisions James’ made to his story as published in the …

Exploring The Influence Of Socioeconomic Status On The Executive Function And Theory Of Mind Skills Of Preschoolers, Andrea Molzhon

Theses and Dissertations

Executive function (EF) and theory of mind (ToM) skills develop rapidly during the preschool years and have been found to directly and indirectly contribute to school readiness. Evidence indicates that EF may influence ToM development, though this relation may not be consistent across children from different backgrounds. Additionally, socioeconomic status (SES) has been shown to affect preschoolers’ EF, while the literature is mixed regarding the effects – if any – that SES may have on ToM development. Though the relation between EF and ToM appears robust across the literature, the possible effects of SES on this relation have yet to …

Are You Covered? Examining How Knowledge Of The Patient Protection And Affordable Care Act Influences Use Of Preventive Reproductive Health Services, Ashlee Sawyer

Theses and Dissertations

The Patient Protection and Affordable Care Act (PPACA) expanded access to insurance coverage and health care services for many citizens, and has increased access for women in particular by including preventive reproductive health services as essential health benefits. The current national rates of sexually transmitted infections (STIs), reproductive cancer diagnoses, and unintended pregnancy serve as major areas of concern for women’s health and public health. The present study examined how knowledge of the PPACA influences receipt of preventive reproductive health services among women. Results indicate that higher levels of knowledge of the PPACA are associated with a greater likelihood of …

Identifying Misconceptions Associated With Inaccurate Survey Reporting In The Combined Use Of Caffeine And Alcohol, Kathryn Polak

Theses and Dissertations

Research on college student use of caffeine combined with alcohol (CAC) and public health concern over such use has been hampered by the absence of psychometrically sound measures of caffeine and CAC use. The present study examined agreement between survey (CAS) and interview (TLFB) methods for collecting data on caffeine, alcohol and CAC use. Participants were N=50 college students randomized to complete CAS followed by TLFB or the reverse. Qualitative follow-up interviews with N=15 participants were used to identify factors contributing to CAS-TLFB discrepancies. Responses varied by method of administration, with largest discrepancy magnitudes found for CAC, followed …
