Does Transdermal Nicotine-Induced Withdrawal Suppression Depend On Smokers' Gender?, Sarah Ellen Evans

Theses and Dissertations

Nicotine replacement therapy (NRT) is a pharmacotherapy used commonly to help tobacco smokers quit smoking. All forms of NRT are demonstrably efficacious for this indication, and several forms, including transdermal nicotine (TN) are available over-the-counter in the United States. NRT is less efficacious in women than in men, although the specific reasons for this gender difference are unknown. NRT generally, and TN specifically, is thought to work, at least in part, by suppressing withdrawal symptoms in abstinent smokers. While TN-induced withdrawal suppression has been demonstrated, the degree to which this withdrawal suppression is influenced by smokers' gender is uncertain. The …

Relation Of Healthcare Provider-Patient Interpersonal Impacts And Health Related Control Appraisals To Patients' Satisfaction And Compliance With Treatment, Thomas A. Campbell

Theses and Dissertations

The current study examined healthcare provider-patient interpersonal impacts and health related control appraisals to patients' satisfaction and compliance with treatment recommendations. Secondary outcomes such as patient satisfaction are becoming increasingly important, and compliance with treatment can have direct effects on primary outcomes. Eighty-one patients at a large, urban university student health center participated in the current study. Participants completed participatory style and interpersonal impact measures both before and after the visit with their provider, and completed satisfaction questionnaires immediately following the visit, and at the two-week follow-up along with a measure assessing compliance with treatment recommendations. Providers also completed interpersonal …

Delivery Of Smoke Toxicants From Cigarettes Made In Developed And Developing Countries: A Comparison Of U.S. Full Flavor And Ultra Light Brands With Syrian Cigarettes, Lynn M. Anderson

Theses and Dissertations

Clinical research is needed to understand how cigarette toxicant yield affects smoker toxicant exposure. While there is much clinical research on yield and exposure in developed countries, there is little in developing countries. Forty smokers completed one, 4-hour session to compare yield and exposure of different cigarettes. Participants smoked three cigarettes under controlled topography conditions: one U.S. 111 flavor, one U.S. ultra light, and one Syrian cigarette, with 90 minutes between cigarettes. Sessions differed by Syrian brand; 21 participants smoked Alhamraa while 19 smoked A1 Sham cigarettes. Blood nicotine and breath CO samples were obtained, HR was monitored and subjective …

Innovative Interventions For Disordered Eating: A Pilot Comparison Between Dissonance-Based And Yoga Interventions, Karen S. Mitchell

Theses and Dissertations

Disordered eating, including bingeing, dieting, purging, and clinical and subclinical forms of anorexia nervosa, bulimia nervosa, and binge eating disorder, is prevalent among college-aged women. To date, few interventions have successfully reduced risk factors related to disordered eating. One promising intervention utilizes principles of cognitive dissonance to reduce thin-ideal internalization among women at risk for eating disorders. Additionally, the benefits of yoga, including increased awareness of bodily processes, offer hope that this practice might reduce disordered eating symptomatology. The current study compared cognitive dissonance and yoga interventions for disordered eating attitudes and behaviors. Hierarchical regression analyses revealed that there were …

Psychosocial Adjustment Of Adolescent Cancer Survivors: Time Perspective And Positive Emotions As Mediators To Quality Of Life And Benefit Finding, Matthew John Bitsko

Theses and Dissertations

Adolescents with cancer are surviving at improved rates with levels of psychopathology in line with their healthy peers. Thus, recent psycho-oncology research is focusing on finding significant predictors to their positive adjustment and psychosocial functioning. The author examined adolescent cancer survivors (n = 50; diagnosis age = 10 – 21; 2 – 10 years post-diagnosis) to test the mediation effects of positive emotionns (satisfaction with life, subjective happiness, and optimism) and time perspective on the outcome variables quality of life and benefit finding with demographic/medical variables (gender, number of treatments received for cancer, and previous psychotherapy) as independent variables. Results …

Complementary And Alternative Medicine And Diet Change In Southern Rural Residents Enrolled In A Cancer Prevention Intervention Trial, Amanda Kracen

Theses and Dissertations

Using data from The Rural Physician Cancer Prevention Project, a dietary intervention trial, this cross-sectional, longitudinal study explored predictors of complementary and alternative medicine (CAM) use in a Southern, rural population (N = 375). Participants' dietary knowledge, stage of change, and dietary behavior were examined at baseline and 1 and 12 months after the intervention. More than half the participants (mean age = 48 years; 60% female; 60% Caucasian) reported using CAM. Logistic regression indicated that age, education, ethnicity and trust in physician affect the likelihood of CAM use. Hierarchical multiple regressions suggested that CAM use was associated with healthier …

Intracellular Ph, The Proximate Signal For Cell Volume Changes That Are Mediated By The Actin Cytoskeleton, William Pasley

Theses and Dissertations

The relationship between initial intracellular pH (pHi) and associated cell volume change was investigated by simultaneous measurement of pHi and cell volume with fluorescence imaging in polarized fungiform taste receptor cells (TRCs) loaded with BCECF in vitro. Ammonium pulses caused a brief, reversible alkalinization in pHi and induced cell swelling. Sodium-acetate pulses reversible decreased TRC pHi and induced cell shrinkage. Removal weak acids and return to Control Ringer's solution (CR) causedTRC pHi and volume to overshoot baseline levels before fully recovering. Replacing CR with zero-sodium solution resulted in irreversible acidification of TRC pHi and induced cell swelling. Addition of sodium …

Parental Memory Predictors Of Children's Daily Diabetes Management And Metabolic Control, Sheryl J. Kent

Theses and Dissertations

This study examined, for the first time, specific links between parents' memory and children's diabetes behaviors and metabolic control. Data revealed that parental memory and responsibility predicted children's percentage of calories from fat and carbohydrates, and metabolic control, accounting for 7.3% of the variance in calories from fat and 18.5% of the variance in metabolic control for the total sample. These effects were stronger when limited to dietary behaviors of younger youth; parental memory accounted for 30.3% and 33.6% of the variance in percentage of calories from fat and carbohydrates, respectively, for younger children. Level of parent responsibility, with memory, …

Assessing The Effects Of Momentary Priming On Memory Retention During An Interference Task, Paul Cameron Schutte

Theses and Dissertations

A memory aid, that used brief (33ms) presentations of previously learned information (target words), was assessed on its ability to reinforce memory for target words while the subject was performing an interference task. The interference task required subjects to learn new words and thus interfered with their memory of the target words. The brief presentation (momentary memory priming) was hypothesized to refresh the subjects' memory of the target words. 143 subjects, in a within subject design, were given a 33ms presentation of the target memory words during the interference task in a treatment condition and a blank 33ms presentation in …

Influences On Career Self-Efficacy: Examining Attachment, Anya Elizabeth Moon

Theses and Dissertations

This study examined the influences of attachment style and level of optimism on career self-efficacy. It was hypothesized that level of optimism moderates the relationship between attachment style and career self-efficacy. Participants were 173 college students who completed the Experiences in Close Relationships (ECR; K.A. Brennan, C.L. Clark, & P.R. Shaver, 1998), the Life Orientation Test - Revised (LOT-R; M. Sheier, C. Carver, & M. Bridges, 1994), and the Career Decision-Making Self-Efficacy - Short Form (CDMSE-SF; N. Betz, K. Klein, & K. Taylor, 1996). The moderator model was not supported, but hierarchical regression revealed a positive relationship between optimism and …

An Exploration Of Impediments To Attachment In A Juvenile Offender Population: Comparisons Between Juvenile Sex Offenders, Juvenile Violent Offenders And Juvenile Non-Sex, Non-Violent Offenders, Sharon Kay Funari

Theses and Dissertations

This current study addresses potential impediments to attachment that may differentiate between incarcerated juveniles who have committed sexual crimes and incarcerated juveniles who have not committed such offenses. The exploration of such potential barriers to attachment has been organized around Bronfenbrenner's Ecological Model. Subjects were 2948 incarcerated male adolescents adjudicated to the Virginia Department of Juvenile Justice and were divided based solely upon adjudicating offense: Juvenile non-violent, non-sexual offenders (JNVNSO, n=1149), Juvenile violent, non-sexual offenders (JVNSO, n=1433) and Juvenile sexual offenders (JSO, n=366). Results indicated that JSOs differed from JNVNSOs and JVNSOs in their histories of sexual abuse as well …

Substance Abuse And Psychosocial Factors In The Hepatitis C Population: Identifying Risk Factors In Disease Severity And Quality Of Life, Jill Courtney Clarida

Theses and Dissertations

Hepatitis C is the most common chronic blood-borne infection in the United States. Research has focused on contributing factors to the development and progression of liver disease, but few studies have considered nicotine use as a potential prognostic factor with CHC. Research has commonly found that CHC patients report with a diminished quality of life. Several factors have been proposed to account for a decrease in QOL; however, the mechanisms underlying the impairment in QOL have not yet been elicited. 76 CHC patients completed self-report measures on a variety of psychosocial variables and biochemical data for determining the patient's liver …

Estimating The Beginning Of The Waterpipe Epidemic In Syria, Samer Rastam, Kenneth D. Ward, Thomas Eissenberg, Wasim Maziak

Psychology Publications

Background

Waterpipe smoking is becoming a global public health problem, especially in the Eastern Mediterranean region (EMR).

Methods

We try in this study, which is a cross sectional survey among a representative sample of waterpipe smokers in cafes/restaurants in Aleppo-Syria, to assess the time period for the beginning of this new smoking hype. We recruited 268 waterpipe smokers (161 men, 107 women; mean age ± standard deviation (SD) 30.1 ± 10.2, response rate 95.3%). Participants were divided into 4 birth cohorts (≤ 1960, 1961–1970, 1971–1980, >1980) and year of initiation of waterpipe smoking and daily cigarette smoking were plotted according …

The Effects Of Aniracetam Treatment On Cognitive Performance And Ampa Receptor Glur2 Subunit Expression After Moderate Fluid Percussion Injury In Rats, Anna Igorevna Baranova

Theses and Dissertations

In addition to the acute pathology produced by traumatic brain injury, there are chronic alterations that occur after the trauma, including a depressed state of neuronal activity (Feeney, 1991). This study included a preclinical testing of a novel treatment strategy focusing on increasing neuronal activity during the chronic hypofunctional posttraumatic stage. The present investigation tested the effects of repeated post-injury aniracetam administration on cognitive performance in the Morris water maze (MWM) and on the GluR2 - immunoreactivity and protein expression by Western blot analysis in the hippocampus. The first study examined the optimal dose of aniracetam in the MWM task. …

The Social Network And Attachment Bases Of Loneliness, David M. Ouellette

Theses and Dissertations

This thesis tests Robert S. Weiss's 1973 theory of loneliness, which claims two types of loneliness: emotional and social. Emotional loneliness is the affective reaction to the absence of a close attachment bond. Social loneliness stems from inadequate integration into a social network. Undergraduate residents of a university dormitory completed questionnaires on loneliness, attachment, personality, and relationships with other dorm residents. Patterns of relational ties among participants were evaluated using social network analysis, specifically density, tie strength, and four forms of centrality. Results reveal that, while controlling for neuroticism, the network measure of outdegree and the two attachment dimensions accounted …

Gender And Ethnic Differences In Perceived Stress As A Predictor Of Smoking Behaviors In Rural Adolescents, Lashanda R. Jones

Theses and Dissertations

Cross-sectional and longitudinal analyses were conducted to examine the impact of perceived stress on current and future smoking behaviors of rural Virginia middle school students. Data were analyzed for 685 sixth grade students and 554 seventh grade students. Sixth grade students were 52% male, 53% Caucasian American (CA), and 47% African American (AA). For 7th graders, the sample was 53% female and 56% CA (44% AA). Of the 685 sixth grade students, 7% reported that they had smoked cigarettes at least once during the past 30 days (n=46,63% male and 67% CA). By the 7th grade, the percentage of smokers …

Childhood Exposure To Interparental Conflict: Memory Biases And Intergenerational Patterns Of Conflict In Romantic Relationships, Christine A. Nelson

Theses and Dissertations

Testing a model that explains the ways in which interparental conflict shapes later intimate relationships was the goal of the present study. Participants were 94 college students at Virginia Commonwealth University, a large state university with a diverse student body. The study found that violence occurs with alarming frequency in the dating relationships of university students. Analyses also revealed an intergenerational pattern of violence in which individuals from high conflict homes were more likely to use violent conflict resolution strategies in their own adult romantic relationships. Specifically, young adults from homes characterized by high levels of verbal conflict and minor …

Memory Matters Ii: Predictors Of Self-Care Behaviors In Young Adults With Type 1 Diabetes, Sari A. Soutor

Theses and Dissertations

Type 1 diabetes and associated hypoglycemia can result in verbal memory difficulties, yet the role of memory in daily diabetes self-care has not been evaluated for young adults. Subtests from two well-standardized memory measures were administered to 34 young adults with type 1 diabetes, aged 18-29, in this pilot study. Self-care behaviors were assessed through 24-hour diabetes care interviews, while HbAlc indicated metabolic control. Verbal associative memory uniquely accounted for 12% of the variance in blood glucose testing frequency (p p p p = .06. Single-trial verbal memory uniquely predicted 10% of the variance in metabolic control (p p < .05. Importantly, memory was the only significant predictor in each model, which indicates memory, rather than overall cognitive capacity or financial/educational resources, relates to self-care behaviors/health status. Memory, a novel factor not previously evaluated in the quest to better understand daily disease management for young adults with diabetes, is significantly related to central self-care behaviors and metabolic control. Memory predictors likely warrant additional research and clinical attention such that eventually, intervention studies might identify strategies or compensatory aids that could improve young adults' self-care behaviors and health status through facilitating better memory functioning.

Emotion Perception In Asperger's Syndrome And High-Functioning Autism: The Importance Of Diagnostic Criteria And Cue Intensity, Carla Ann Mazefsky

Theses and Dissertations

Asperger's syndrome (AS) is a pervasive developmental disorder that is associated with marked social dysfunction. Deficits in the perception of nonverbal cues of emotion may be related to this social impairment. Research has indicated that children with autism are limited in their emotion perception abilities, but studies that have addressed this issue with individuals with AS or high-functioning autism (HFA) have yielded inconsistent findings. These inconsistencies may be related to methodological differences across studies including diagnostic criteria and failure to consider the intensity of the emotion cues. It was hypothesized that children with AS and HFA would both have deficits …

Theses and Dissertations

ABSTRACTRECOVERY FROM SUBSTANCE ABUSE: THE ROLE OF UNSUPPORTIVE SOCIAL INTERATIONSBy Michelle M. Schmitt, M.A., M.S. A dissertation submitted in partial fulfillment of the requirements for the degree of Doctor of Philosophy at Virginia Commonwealth University.Virginia Commonwealth University, 2003Major Director: Kathleen M. Ingram, Ph.D., Assistant Professor, Department of Psychology It has been estimated that over 20 million individuals struggle with substance abuse and/or dependence each year. Theories of addiction and recovery have long incorporated the notion of social support and helping relationships to facilitate adjustment. However, the literature investigating the role of social support is fraught with contradictions. In addition, in …

Parental Reports Of The Development Of Autism In Their Children: The Relevance Of Regression, Comorbidity, And Genetics In The Detection Ofearly Characteristics, Robin Page Goin

Theses and Dissertations

Early detection of autism plays an important role in enhancing developmental outcomes for affected children. Identifying potential characteristics of the disorder evident during infancy and toddlerhood aids efforts to screen for such symptoms, which may lead to earlier and more accurate diagnoses; however, it is unclear to what extent certain factors encourage or impede early detection. Because parents are responsible for making decisions on behalf of their children based upon their perceptions of children's developmental progression, caregivers were queried in terms of their beliefs about the development of autism characteristics in their children. Participants included 393 caregivers of children with …

Effects Of Domestic Violence Exposure In Colombian Adolescents: Pathways To Violent And Prosocial Behavior, Roberto Mejia

Theses and Dissertations

A multidimensional model of associations between domestic violence exposure and risk of violence and prosocial behavior was tested in a sample of Colombian adolescents, with attention to impulsivity and substance use problems as mediators of these associations. A representative sample of 1,152 school youths and a convenience group of 148 juvenile offenders aged 11-19 years was recruited from Medellin, the second largest city in this South American country. Assessment was carried out in classrooms in the school sample and in correctional institutions for juvenile offenders. Structural Equation Modeling (SEM) was utilized to test the conceptually derived models. Similarly, multisample analyses …

Environmental Factors That Predict Adolescent Smoking Behavior: The Influence Of Parent, Peer, And Sibling Smoking, Christopher J. Hogan

Theses and Dissertations

The majority of adult smoking begins during adolescence, and in order for prevention programs to be optimally effective it is critical to understand the influences of smoking initiation during this developmental period. However, little research has focused on how environmental factors, such as parent and peer smoking. influence smoking initiation exclusively within a rural population. The current study surveyed students from 23 middle schools in rural Virginia and New York State at the end of the sixth grade and then one-year later at the end of the seventh grade. Logistic regressions were used to predict changes in levels of adolescent …

Gaba-A Receptor Subunit Alterations Following Experimental Traumatic Brain Injury And The Effects Of An Nmda Antagonist: A Western Blot Analysis, Cynthia J. Gibson

Theses and Dissertations

Traumatic brain injury (TBI) produces an acute phase of neuronal excitation followed by a chronic phase of depressed neuronal function. Alterations in excitatory and inhibitory receptor interactions may be dynamically involved in subsequent long-term detriments in neuronal and cognitive functioning. TBI- induced elevations in intracellular calcium concentrations ([Ca²⁺]_i) are mediated primarily by the NMDA receptor. Elevated [Ca²⁺]_i may trigger intracellular mechanisms which drive changes in GABA-A receptor protein synthesis and expression, ultimately resulting in receptor dysfunction.

Western blot analysis was used to investigate alterations to GABA-A receptor subunits α1 and β33 in the …

Background

Patients with chronic forms of major depression are difficult to treat, and the relative efficacy of medications and psychotherapy is uncertain.

Methods

We randomly assigned 681 adults with a chronic nonpsychotic major depressive disorder to 12 weeks of outpatient treatment with nefazodone (maximal dose, 600 mg per day), the cognitive behavioral-analysis system of psychotherapy (16 to 20 sessions), or both. At base line, all patients had scores of at least 20 on the 24-item Hamilton Rating Scale for Depression (indicating clinically significant depression). Remission was defined as a score of 8 or less at weeks 10 and 12. For …

Acute Gaba-A Receptor Modulation By Diazepam Following Traumatic Brain Injury In The Rat: An Immunohistochemical Study, Cynthia J. Gibson

Theses and Dissertations

Traumatic brain injury (TBI) disrupts ionic balance and produces acute widespread depolarization. Restoration of ionic balance and neuronal function after TBI may be achieved by increasing inhibitory neurotransmission (e.g., stimulating GABA-A receptors). This study used antibodies specific for β2/3 subunits to examine changes in GABA-A receptors in the rat hippocampus 24 hours following moderate fluid percussion TBI. The β2/ 3 antibody primarily stained dendritic processes. No injury related changes were found in the CA1 but extensive morphological dendritic alterations were found in the CA3 region of the hippocampus. Analysis revealed decreased length of immunoreactive processes in CA3 apical dendrites of …

The Impact Of A Peer-Led Program On The Peer Leaders' Leadership-Related Skills, Christopher J. Hogan

Theses and Dissertations

Leadership and goal setting skills were examined for 49 high school students who implemented a peer-led health and life skills program for sixth grade students. Participants completed surveys that included a leadership scale and a goal setting scale constructed for this study. and an adapted version of the Goals Inventory. Surveys were administered to the participants prior to a 3-day training (Time Point I), immediately following the training (Time Point 2). and at the completion of leading 12. 1-hour workshops (Time Point 3). The results indicate that high school peer leaders perceived an increase in both their leadership and goal …

Theses and Dissertations

This study examined the effectiveness of couple enrichment using currently-accepted standards of meta-analytic research, including analysis based upon both fixed-effects and random effects models. Ninety published and unpublished studies comparing enrichment groups to control groups were included in the analyses. The overall mean effect size (0.23) for couple enrichment was heterogeneous, positive, and significantly different than 0. Mean effect sizes for both post-treatment and follow-up did not differ significantly. Methodological and substantive moderator variables associated with publication date, publication source, program type, program length, latency of measurement, mode of measurement, measure type, measure/program congruence, design quality, and researcher allegiance were …

Unsupportive Social Interactions As Moderators Of Adjustment In Acute Cardiac Patients, Scott L. Green

Theses and Dissertations

The purpose of the present study was to examine the impact of unsupportive social interactions, within Lazarus and Folkman's (1984) cognitive appraisal model, on individual's mood states following an acute cardiac event (i.e., myocardial infarction, percutaneous transluminal coronary angioplasty, coronary artery bypass grafting). It was hypothesized that unsupportive social interactions would exacerbate the effects of a patient's appraisals of threat secondary to an acute cardiac event. Participants in the present investigation were 67 patients from the cardiology unit of the Veterans Administration Medical Center in Richmond, Virginia. Each participant had incurred an acute cardiac event, as classified by the International …

The Use Of A Habit Reversal Treatment For Chronic Facial Pain In A Minimal Therapist Contact Format, Donald R. Townsend

Theses and Dissertations

The temporomandibular disorders (TMD) diminish quality of life and can be costly for both individuals and the health care system. Stress from a variety of factors, including daily hassles and maladaptive thought patterns, has been commonly cited as a contributing factor in TMD. Support for this hypothesis comes from research demonstrating masseter muscle hyperactivity in response to experimental stressors, such as painful or frustrating stimuli. Many believe the link between stress and increased masseter muscle pain is parafunctional oral habits, including teeth clenching, grinding, and lip biting. Habit reversal has been used effectively to treat parafunctional oral behaviors and facial …
