Physical Aggressiveness And Gray Matter Deficits In Ventromedial Prefrontal Cortex, David S. Chester, Donald R. Lynam, Richard Milich, C. Nathan Dewall

Psychology Faculty Publications

What causes individuals to hurt others? Since the famous case of Phineas Gage, lesions of the ventromedial prefrontal cortex (VMPFC) have been reliably linked to physically aggressive behavior. However, it is unclear whether naturally-occurring deficits in VMPFC, among normal individuals, might have widespread consequences for aggression. Using voxel based morphometry, we regressed gray matter density from the brains of 138 normal female and male adults onto their dispositional levels of physical aggression, verbal aggression, and sex, simultaneously. Physical, but not verbal, aggression was associated with reduced gray matter volume in the VMPFC and to a lesser extent, frontopolar cortex. Participants …

Influence Of Dietary Salt Knowledge, Perceptions, And Beliefs On Consumption Choices After Stroke In Uganda, Martin N. Kaddumukasa, Elly Katabira, Martha Sajatovic, Svetlana Pundik, Mark Kaddumukasa, Larry B. Goldstein

Methods

Convergent parallel mixed methods triangulation design comprised a cross-sectional survey (n = 81) and 8 focus group discussions with 7-10 poststroke participants in each group. We assessed participant characteristics and obtained insights into their salt consumption attitudes, perceptions, and knowledge. Qualitative responses were analyzed using an inductive approach with thematic analytic procedures. Relationships …

High Trait Shame Undermines The Protective Effects Of Prevalence Knowledge On State Shame Following Hpv/Cin Diagnosis In Women, Sarah Mcqueary Flynn, Tory A. Eisenlohr-Moul, Suzanne C. Segerstrom, Christen T. Logue, Jamie L. Studts

Psychology Faculty Publications

Human papillomavirus (HPV), and the related, cervical intraepithelial neoplasia (CIN), are common yet poorly understood physical conditions. The diagnosis of HPV often elicits shame and guilt, which in turn may undermine psychological and physical health. The current study compared shame and guilt responses to diagnosis among two groups: women diagnosed with HPV/CIN and women diagnosed with Epstein–Barr Virus (EBV/IM). Eighty women recently diagnosed with HPV/CIN or EBV/IM completed measures of shame- and guilt-proneness, shame and guilt following diagnosis, and disease knowledge including prevalence estimates (HPV and EBV, respectively). HPV/CIN (vs. EBV/IM) predicted more diagnosis-related shame and guilt. Estimates of high …

Pathway Of Protection: Ethnic Identity, Self-Esteem, And Substance Use Among Multiracial Youth, Sycarah Fisher, Tamika C. B. Zapolski, Chelsea Sheehan, Jessica Barnes-Najor

Educational, School, and Counseling Psychology Faculty Publications

Fifty percent of adolescents have tried an illicit drug and 70% have tried alcohol by the end of high school, with even higher rates among multiracial youth. Ethnic identity is a protective factor against substance use for minority groups. However, little is known about the mechanisms that facilitate its protective effects, and even less is known about this relationship for multiracial youth. The purpose of the present study was to examine the protective effect of ethnic identity on substance use and to determine whether this relationship operated indirectly through self-esteem, a strong predictor of substance use for among adolescent populations. …

A Longitudinal Study Of The Reciprocal Relationship Between Ever Smoking And Urgency In Early Adolescence, Jessica L. Burris, Elizabeth N. Riley, Gabriella E. Puleo, Gregory T. Smith

Psychology Faculty Publications

Background—Among early adolescents in the United States (U.S.), the prevalence of cigarette smoking is at its lowest level in recent decades. Nonetheless, given the risks of smoking in early development, it remains critically important to study both risk factors for smoking and risks from smoking. This longitudinal study with U.S. early adolescents examines smoking initiation and tests a model of reciprocal prediction between ever smoking and the personality trait of urgency (i.e., mood-based impulsivity), a trait that increases risk for multiple forms of dysfunction.

Methods—Participants (n=1906; 90% 10–11 years old, 50% female, 39% racial minorities at …

The Development And Evaluation Of A Smartphone Nutrition Intervention For Adolescents, Sarah A. Cappuccitti

Electronic Thesis and Dissertation Repository

A diet high in fruit and vegetables is associated with the prevention of many chronic diseases; however, only one in ten Canadian students in grades 6 to 12 consume the recommended daily intake of fruits and vegetables. Using smartphones to deliver nutrition interventions is an emerging area of research, although to-date these interventions typically limit their focus to weight loss. The overarching purpose of this research is to redevelop and evaluate an existing smartphone application for an adolescent population. This thesis used a mixed-methods approach to gain adolescent perspectives on how to redevelop the app and to evaluate its use …

An Initial Application Of A Biopsychosocial Framework To Predict Posttraumatic Stress Following Pediatric Injury, Meghan L. Marsac, Nancy Kassam-Adams, Douglas L. Delahanty, Jeffrey Ciesla, Danielle Weiss, Keith F. Widaman, Lamia P. Barakat

Pediatrics Faculty Publications

Objectives—Each year millions of children suffer from unintentional injuries that result in poor emotional and physical health. This study examined selected biopsychosocial factors (i.e., child heart rate, peritrauma appraisals, early coping, trauma history) to elucidate their roles in promoting emotional recovery following injury. The study evaluated specific hypotheses that threat appraisals (global and trauma-specific) and coping would predict subsequent posttraumatic stress symptoms (PTSS), that coping would mediate the association between early and later PTSS, and that heart rate would predict PTSS and appraisals would mediate this association.

Method—Participants were 96 children hospitalized for injury and assessed at 3 …

Examining The Protective Effect Of Ethnic Identity On Drug Attitudes And Use Among A Diverse Youth Population, Tamika C. B. Zapolski, Sycarah Fisher, Devin E. Banks, Devon J. Hensel, Jessica Barnes-Najor

Educational, School, and Counseling Psychology Faculty Publications

Ethnic identity is an important buffer against drug use among minority youth. However, limited work has examined pathways through which ethnic identity mitigates risk. School-aged youth (N = 34,708; 52 % female) of diverse backgrounds (i.e., African American (n = 5333), Asian (n = 392), Hispanic (n = 662), Multiracial (n = 2129), Native American (n = 474), and White (n = 25718) in grades 4–12 provided data on ethnic identity, drug attitudes, and drug use. After controlling for gender and grade, higher ethnic identity was associated with lower past month drug use …

Implementation Of The National Asthma Guidelines In A Residential Pediatric Clinic, Patricia A. Foster-Staples

Dissertations

Abstract

Purpose: Foster care children admitted to residential facilities are a unique and vulnerable group, many presenting with undiagnosed or poorly managed asthma. The alarming rate of residents admitted to a particular residential primary care clinic with a diagnosis of asthma led to the project question: “Based on record reviews, does staff education about the importance of utilizing the national guidelines for asthma education influence the implementation of such guidelines in a residential pediatric clinic?” The purpose of this quality improvement project was to implement a systematic process to influence practice change. The project was conducted over a period …

Traumatic Brain Injury In Adolescence: The Relationship Between High School Exiting And Future Productivity, Jeffrey S. Garofano

USF Tampa Graduate Theses and Dissertations

Traumatic brain injury (TBI) is the leading cause of death and disability among children and adolescents. Brain injury survivors are often left with persistent impairments that have the potential to impede daily functioning, delay or prevent the attainment of developmental milestones, and subsequently limit future productivity in adulthood. A shared goal of both neurorehabilitation and the educational system is to prepare youth for a productive adulthood with both systems of care having substantial, yet independent, literature bases regarding factors associated with productivity (e.g., engagement in employment or post-secondary education). It is currently assumed that because type of high school exiting …

Social Rejection Magnifies Impulsive Behavior Among Individuals With Greater Negative Urgency: An Experimental Test Of Urgency Theory, David S. Chester, Donald R. Lynam, Richard S. Milich, C. Nathan Dewall

Psychology Faculty Publications

Impulsivity is a multifaceted trait with substantial implications for human well-being. One facet of impulsivity is negative urgency, the tendency to act impulsively in response to negative affect. Correlational evidence suggests that negative affect magnifies impulsive behavior among individuals with greater negative urgency, yet causal evidence for this core pillar of urgency theory is lacking. To fill this gap in the literature, participants (N = 363) were randomly assigned to experience social rejection (a situation shown to induce negative affect) or acceptance. Participants then reported their subjective negative affect, completed a behavioral measure of impulsivity, and reported their negative …

Rapid Statistical Learning Supporting Word Extraction From Continuous Speech., Laura J Batterink

Brain and Mind Institute Researchers' Publications

The identification of words in continuous speech, known as speech segmentation, is a critical early step in language acquisition. This process is partially supported by statistical learning, the ability to extract patterns from the environment. Given that speech segmentation represents a potential bottleneck for language acquisition, patterns in speech may be extracted very rapidly, without extensive exposure. This hypothesis was examined by exposing participants to continuous speech streams composed of novel repeating nonsense words. Learning was measured on-line using a reaction time task. After merely one exposure to an embedded novel word, learners demonstrated significant learning effects, as revealed by …

Methods

SIREN is a transnational, multicenter study involving acute stroke patients and age-, ethnicity-, and sex-matched control subjects recruited from 9 sites in Ghana and Nigeria. Genomic and environmental risk factors and other relevant phenotypes for stroke and …

Serious Mental Illness Among Young Adult Women Who Use Drugs In The Club Scene: Co-Occurring Biopsychosocial Factors, Maayan Lawental, Hilary L. Surratt, Mance E. Buttram, Steven P. Kurtz

Center for Health Services Research Faculty Publications

Young women who regularly attend nightclubs are at risk for numerous health and social consequences, including mental distress, sexual and physical victimization and substance dependence. This paper uses a biopsychosocial framework to examine co-occurring mental health problems, victimization, substance dependence, sexual risk and physical pain among a sample of young women who use drugs (N = 222) in Miami’s club scene. The majority of women were under 24 years old, Hispanic, and identified as heterosexual. Almost all the women reported past 90-day use of alcohol, ecstasy/MDMA, marijuana, cocaine and prescription opioids and benzodiazepines; 32% of women reported being in a …

Online Neural Monitoring Of Statistical Learning., Laura J Batterink, Ken A Paller

Brain and Mind Institute Researchers' Publications

The extraction of patterns in the environment plays a critical role in many types of human learning, from motor skills to language acquisition. This process is known as statistical learning. Here we propose that statistical learning has two dissociable components: (1) perceptual binding of individual stimulus units into integrated composites and (2) storing those integrated representations for later use. Statistical learning is typically assessed using post-learning tasks, such that the two components are conflated. Our goal was to characterize the online perceptual component of statistical learning. Participants were exposed to a structured stream of repeating trisyllabic nonsense words and a …

The Juvenile Justice Behavioral Health Services Cascade: A New Framework For Measuring Unmet Substance Use Treatment Services Needs Among Adolescent Offenders, Steven Belenko, Danica Knight, Gail A. Wasserman, Michael L. Dennis, Tisha Wiley, Faye S. Taxman, Carrie B. Oser, Richard Dembo, Angela A. Robertson, Jessica Sales

Sociology Faculty Publications

Overview—Substance use and substance use disorders are highly prevalent among youth under juvenile justice (JJ) supervision, and related to delinquency, psychopathology, social problems, risky sex and sexually transmitted infections, and health problems. However, numerous gaps exist in the identification of behavioral health (BH) problems and in the subsequent referral, initiation and retention in treatment for youth in community justice settings. This reflects both organizational and systems factors, including coordination between justice and BH agencies.

Methods and Results—This paper presents a new framework, the Juvenile Justice Behavioral Health Services Cascade (“Cascade”), for measuring unmet substance use treatment needs to …

Intimate Partner Violence And Women's Cancer Quality Of Life, Ann L. Coker, Diane R. Follingstad, Lisandra S. Garcia, Heather M. Bush

CRVAW Faculty Journal Articles

Purpose

Because intimate partner violence (IPV) may disproportionately impact women’s quality of life (QOL) when undergoing cancer treatment, women experiencing IPV were hypothesized to have (a) more symptoms of depression or stress and (b) lower QOL as measured with the Functional Assessment of Cancer Therapy (FACT-B) and Functional Assessment of Chronic Illness Therapy—Spiritual Well-being (FACIT-SP) Scales relative to those never experiencing IPV.

Methods

Women, aged 18–79, who were included in one of two state cancer registries from 2009 to 2015 with a recent incident, primary, invasive biopsy-confirmed cancer diagnosis were recruited and asked to complete a phone interview, within 12 …

Protective Behavioral Strategies As A Context-Specific Mediator: A Multilevel Examination Of Within- And Between-Person Associations Of Daily Drinking, Abby L. Braitman, Ashley N. Linden-Carmichael, James M. Henson

Psychology Faculty Publications

Research indicates that a drinker’s environmental and social context can be differentially associated with drinking outcomes. Further, although many researchers have identified that more frequent use of protective behavioral strategies (PBS) is associated with lower alcohol consumption and negative consequences, scant research has examined how one’s drinking context may promote or hinder PBS use. The present study examined how the context of drinking each day (i.e., where and with whom) is associated with level of consumption and reported alcohol-related problems among n = 284 college drinkers (69.0% female) directly, as well as indirectly through the use of PBS. Two different …
