Sugar Consumption And Cognitive Aging In The Swedish Adoption/Twin Study Of Aging, Shyam Seetharaman

USF Tampa Graduate Theses and Dissertations

Abstract

Consumption of foods high in sugar content has been linked with the development of metabolic abnormalities such as cardiovascular disease and type II diabetes, major sources of global health concerns. Although the detrimental consequences of high intake of sugar on abnormal metabolic processes are established, it is not known how this association affects (or accelerates) cognitive aging.

The current project was based on data from the Swedish Adoption/Twin Study of Aging (SATSA) to test the hypothesis that high refined sugar intake contributes to accelerated trajectories of cognitive decline assessed longitudinally. Trajectories of cognitive change were assessed as a function …

Quality Of Life In Adult Obsessive-Compulsive Disorder: The Role Of Moderating And Mediating Variables, Brittany Belle Speisman

USF Tampa Graduate Theses and Dissertations

Background: This study examined the contribution of various aspects of obsessive-compulsive disorder (OCD) on quality of life (QoL) in 102 adults with a principal diagnosis of OCD from an archival database.

Further information was attained using the Beck Depression Inventory II (BDI-II), the Obsessive Compulsive Inventory Revised (OCI-R) and the Medical Outcome Study-36 (MOS-36). Results: Results indicated that obsessive-compulsive symptom severity was positively correlated with diminished emotional health, social …

A Dual-Factor Model Of Mental Health In High School Students: Group Characteristics And Social Functioning, Amanda Lynn Thalji

USF Tampa Graduate Theses and Dissertations

A dual-factor model of psychological functioning examines the presence of wellness (i.e., subjective well-being; SWB) and psychopathology (i.e., internalizing and externalizing behavior problems) in explaining youth mental health functioning. Using a dual-factor model, previous research has yielded four unique groups of elementary and middle school youth as well as college-age adults with distinct levels of wellness and psychopathology. The present empirical investigation included valid data from 500 adolescents from two high schools (grades 9 to 11). This exploratory study produced four groups of students with unique mental health profiles aligned with previous studies investigating the dual-factor model. Tukey-Kramer comparisons determined …

The Mediating Role Of Regulatory Focus In The Relationship Between Transformational/Transactional Leadership And Follower Work Outcomes, Erin J. Walker

USF Tampa Graduate Theses and Dissertations

The purpose of this research was to integrate the areas of leadership and motivation by examining how leaders' behaviors affect their followers' regulatory foci. Specifically, a separate laboratory experiment and field survey were conducted to determine whether leader transformational and transactional behaviors shape followers' work-based promotion and prevention regulatory foci, which in turn affect followers' outcomes at work. Overall, there was limited evidence that inspirational motivation and contingent reward leader behaviors were related to follower work-based regulatory focus, and work-based regulatory focus was related to several work-related outcomes. The moderating role of chronic regulatory focus on the relationship between leader …

Autism Spectrum Disorders (Asd): Knowledge, Training, Roles And Responsibilities Of School Psychologists, Stacey Small

USF Tampa Graduate Theses and Dissertations

The number of students with autism spectrum disorders (ASD) has increased over the years and therefore it seems inevitable that school psychologists will encounter these students as part of their roles in assessment, consultation, and/or intervention. There are a multitude of articles and books on the signs and symptoms of ASD, as well as suggestions for assessment and intervention, but there are no published data related to school psychologists' knowledge, training, and roles and responsibilities for students with ASD. Therefore, the current study sought to inform the field of school psychology with respect to these issues. One hundred members of …

Gender Differences In Subtypes Of Workplace Aggression, Zhiqing Zhou

USF Tampa Graduate Theses and Dissertations

The purpose of the current study was to categorize workplace aggression into nine subtypes based on human aggression and workplace aggression literature, and to examine gender differences in engaging in these subtypes of workplace aggression. Data collected from 366 employed students showed that a significant gender difference was found only in direct workplace aggression and there were no gender differences in the other eight workplace aggression subtypes; verbal, direct, and passive workplace aggression was more frequently used than physical, indirect and active workplace aggression, respectively. Data collected from 83 employee-supervisor pairs showed that compared to supervisors' reports, female employees' self-reports …

The Effects Of Informational Prompts And Performance Feedback On Recyclign Behavior, Erin Marie Zandecki

USF Tampa Graduate Theses and Dissertations

Recycling behavior was examined by the implementation of Informational Prompts and Performance Feedback. Prompts containing facts on recycling and waste along with group performance feedback were studied at The Florida Mental Health Institute at The University of South Florida (Tampa campus). Informational Prompts were introduced by placing informational facts about recycling and waste by 26 bins throughout the building. Performance feedback signs were placed by the same bins and included the frequency of recycled material and trash discarded in the recycling bins on a daily basis when the campus was open. The results showed that both interventions increased recycling. Informational …

Training Deictic Relational Responding In People With Schizophrenia, John O'Neill

USF Tampa Graduate Theses and Dissertations

The purpose of this study was to replicate and extend recent findings in the functional contextual literature by 1) establishing complex deictic relational responding skills in 3 persons diagnosed with Schizophrenia and mild-moderate Mental Retardation and 2) assessing generalization through pre and post-instructional measures of Social Anhedonia and Theory of Mind functioning. Results suggest that increasingly complex levels of deictic relational responses were acquired and mastered by all 3 participants and that generalization extended to the Deceptive Container Task (ToM levels 4 & 5) and Hinting Task. Support is provided for the notion that perspective taking skills might be shaped …

Inter-Rater Reliability Of The Anxiety Disorders Interview Schedule For Dsm-Iv In High Functioning Children And Adolescents With Autism Spectrum Disorder, Danielle Ung

USF Tampa Graduate Theses and Dissertations

The present study examined inter-rater agreement on the Anxiety Disorder Interview Schedule DSM-IV Child and Parent Interview (ADIS-IV-C/P) in youth with autism spectrum disorder and if age and ASD diagnosis moderated agreement. Diagnoses established for 70 7-16-year-old youth with ASD during a live administration of the ADIS-IV-C/P were compared to diagnoses identified by a second rater after listening to audiotaped recordings of the interviews. Inter-rater agreement on parent and child reports was excellent (k=1.00). Inter-rater agreement on principal diagnoses (k=0.91), individual anxiety diagnoses (k=0.85-0.97), and other comorbid diagnoses (i.e., major depressive disorder, dysthymia, oppositional defiant disorder, attention deficit hyperactivity disorder-Inattention/Hyperactivity/Combined …

Trust Development In Distributed Teams: A Latent Change Score Model, Evgeniya Pavlova

USF Tampa Graduate Theses and Dissertations

Advances in collaborative work tools and communication technologies have made computer-mediated teams a part of virtually every organization. One of the challenges for members of virtual teams is the development of trust. This study examined the reciprocal relationship between trust and effectiveness in virtual teams, employing an input-process-output-input approach. Data were collected from 183 individuals comprising 61 teams. Teams participated in a computer-simulated search and rescue mission. Three alternative latent change score structural equation models were fit to the data to examine the bidirectional relationships between trust and effectiveness. Results revealed that the two

factors of trust, cognition-based trust and …

For Better Or Worse: An Examination Of The Antecedents And Outcomes Of Mentor Commitment In Mentoring Relationships, Laura Poteat

USF Tampa Graduate Theses and Dissertations

This study examined a model of the antecedents and outcomes of mentor commitment to workplace mentoring relationships. The proposed model was based on the investment model of commitment. A total of 180 pairs of mentors and their protégés completed surveys that assessed model constructs. Results indicated that mentor relationship satisfaction and investment size predict mentor commitment, whereas mentor quality of alternatives and perceptions of managerial support for mentoring do not predict mentor commitment. Additionally, mentor commitment is associated with information exchange behaviors engaged in by mentors and protégés. These findings suggest that commitment plays an important role in mentoring relationships, …

Emotion-Modulated Startle And The Course Of Major And Minor Depression, April Taylor-Clift

USF Tampa Graduate Theses and Dissertations

Major depressive disorder (MDD) is highly recurrent. Researchers have proposed that certain traits predispose people to repeated episodes of this disorder. The current study examined the hypothesis that maladaptive emotional responding to stimuli would predict a worse depression outcome over six months. Participants were 58 individuals--18 controls, 22 individuals with MDD, and 18 individuals with minor depression (mD; subthreshold depression)--who participated in a diagnostic interview and emotion-modulated startle procedure at time one, and who returned for a second diagnostic interview six months later at time two. An identical emotion-modulated startle procedure was then repeated at time two with 33 individuals--12 …

Cultivating An Engaged Workforce: The Roles Of Leader Personality, Motivation, And Leadership Style, Amy Marie Taylor

USF Tampa Graduate Theses and Dissertations

This study explored the links between leadership style, leader personality, and motivation to lead, with employee engagement. Transformational leadership, transactional leadership, and abusive supervision styles were examined in relation to levels of employee engagement via a sample of n=195 employees and n=130 managers. Consistent with findings from Christian, Garza, and Slaughter (2011), transformational leadership showed a positive link to employee engagement (r= .38, p< .05). On the opposite end, abusive supervision was negatively related to employee engagement (r= -.27, p< .05). Contingent reward leadership showed a positive link to employee engagement (r= .32, p< .05).

Relationships between personality and leadership style were framed according to the socioanalytic framework (Hogan & Shelton, 1998). This study did not find any significant differences in the relationships between the expected leadership behaviors and the traits …

Deconstructing The "Power And Control Motive": Developing And Assessing The Measurability Of Internal Power, Shelly Marie Wagers

USF Tampa Graduate Theses and Dissertations

Despite the increased social recognition, law and policy changes within the criminal justice system, and the widespread use of court mandated batterer intervention programs (BIPs) domestic violence continues to be a persistent problem. The lack of significant decline in incidence rates along with a growing body of empirical evidence that indicates BIPs are, at best, only moderately effective raises serious concern. Effective policies and programs are based upon empirically tested theory. The assertion "the batterer's motive is power and control" has become fundamental to almost all of our currently used and accepted mainstream theoretical explanations regarding domestic violence. However, the …

Enhancing Training Outcomes In The Context Of E-Learning: The Impact Of Objective Learner Control, Training Content Complexity, Cognitive Load, Learning Goal Orientation, And Metacognitive Strategies, Benjamin P. Granger

USF Tampa Graduate Theses and Dissertations

Learner-controlled e-learning has become a preferred medium for the delivery of organizational training. While e-learning offers organizations and trainees many advantages, it also comes with several potential disadvantages. The aim of this study was to explore the relative efficacy of learner- and program-controlled e-learning for content that differs in its complexity. This study also explored cognitive load as a differential mediator of the interaction between learner control and training content complexity for predicting cognitive and behavioral learning outcomes. Finally, learning goal orientation was explored as a motivational individual difference that helps learners cope with complex, learner-controlled e-learning environments. Results suggest …

A Longitudinal Examination Of High School Students' Group Membership In A Dual-Factor Model Of Mental Health: Stability Of Mental Health Status And Predictors Of Change, Melanie M. Mcmahan

USF Tampa Graduate Theses and Dissertations

A dual-factor model of mental health includes indicators of wellness (i.e., subjective well-being; SWB) and psychopathology (i.e., internalizing and externalizing behavior problems) in defining youth mental health. In this model, four categories of psychological functioning with distinct levels of SWB and psychopathology emerge, including two that are overlooked (i.e., Vulnerable and Symptomatic but Content) in traditional assessments that assume SWB and psychopathology are opposite ends of the same continuum. The present study investigated the 1-year stability of adolescent mental health as classified by a dual-factor model, and identified predictors of stability and change, in a sample of 425 high school …

Listening In Action: Students' Mobile Music Experiences In The Digital Age, Rebecca Marie Rinsema

USF Tampa Graduate Theses and Dissertations

Since the introduction of the iPod in 2001, portable music listening devices that play or stream compressed music files have steadily become the standard devices used to listen to music. Despite this, few music education researchers have investigated the role that such devices have in shaping students' music listening experiences. This dissertation is meant to fill that gap in the literature and contribute to the existing sociological and psychological literature on music listening in everyday life.

Phenomenology served as the theoretical framework for the design of the study. 10 college students from three institutions underwent iterative interviews and were asked …

An Analysis Of Shifting Preferences For Tasks Involved In Contingency Schedules, Sarah Sinai

USF Tampa Graduate Theses and Dissertations

Abstract

This experiment evaluated the effects of noncontingent and contingent access on relative preference for items identified through a series of preference assessments. Four typically developing children participated in multiple stimulus without replacement preference assessments to establish a relative hierarchy of preferred activities. Following the MSWO, the participants were exposed to contingent access or noncontingent access conditions that were separated by preference assessments to assess stability of the preference hierarchy. Results were discussed in terms of preference, preference shifts, and the response deprivation hypothesis.

The Interrelationships Among Family Stress, Parenting Behavior, And Behavior Problems: An Investigation Of Internationally Adopted Chinese Girls, Cheryl Gelley

USF Tampa Graduate Theses and Dissertations

Although there have been many studies investigating international adoptees' outcomes in relation to their pre-adoption experiences, there is a paucity of research investigating the influence of post-adoption experiences. Guided by the proximity of the family to the child in Bronfenbrenner's (1979) ecological systems theory of human development, this study addressed a gap in the literature by investigating the interrelationships among family-related variables (e.g., stress in family environment, parenting behavior) and 648 internationally adopted Chinese girls' behavior problems. Moderate, positive relationships were found between family stress and both internalizing (r = .43, p < .001) and externalizing (r = .59, p < .001) behavior problems. Modest, inverse relationships were found between authoritative parenting and both internalizing (r = -.08, p < .01) and externalizing (r = -.15, p < .001) behavior problems. Additionally, modest to moderate, positive relationships were found between authoritarian and permissive parenting and internalizing (r = .18, p < .001; r = .19, p < .001, respectively) and externalizing (r = .39, p < .001; r = .34, p < .001, respectively) behavior problems. Finally, authoritarian and permissive parenting behaviors were partial mediators between family stress and both internalizing (R² = .08, p < .001; R² = .08, p …

The Relationships Between Individual Characteristics, Work Factors, And Emotional Labor Strategies In The Prediction Of Burnout Among Mental Health Service Providers, Jessica Belle Handelsman

USF Tampa Graduate Theses and Dissertations

Relatively few empirical studies in the professional burnout literature have examined mental health providers (MHPs). Research on other professional groups has demonstrated that certain emotion regulation strategies, known as emotional labor (i.e., deep acting and surface acting), are common responses to perceived display rules (i.e., professional guidelines for emotional expression), and are differentially associated with burnout. The present study aimed to fill a gap in the literature by evaluating the empirical links between work stressors (i.e., role conflict, role ambiguity, and lack of autonomy), personality (i.e., extraversion), emotional labor (i.e., surface acting and deep acting), and burnout in a sample …

Does Crowding Obscure The Presence Of Attentional Guidance In Contextual Cueing?, Steven William Fiske

USF Tampa Graduate Theses and Dissertations

The contextual cueing effect was initially thought to be the product of memory guiding attention to the target location. However, the steep search slopes obtained in contextual cueing indicate an absence of attentional guidance. We hypothesized that crowding could be obscuring the presence of attentional guidance and investigated this possibility in 2 experiments. Crowding was manipulated by varying the density of items in the local target region in a contextual cueing task. We observed a significant reduction in search slopes between the novel and repeated conditions when crowding was reduced. Enhancing crowding eliminated the contextual cueing effect. These findings suggest …

Emotional Reactivity And Regulation In Current And Remitted Depression: An Event Related Potential Study, Lauren M. Bylsma

USF Tampa Graduate Theses and Dissertations

Major Depressive Disorder (MDD) is thought to be characterized by emotion regulation deficits, including decreased use of adaptive strategies such as reappraisal, but little is known about the exact nature of these deficits and whether or not they are specific to the depressed mood state. The late positive potential (LPP) is a sustained positive deflection of the event-related potential (ERP) associated with responding to emotionally-valenced stimuli, and reappraisal strategies have been found to reduce LPP magnitude in response to emotional stimuli in healthy individuals, but this effect has not been examined in MDD. This study utilized ERPs to examine emotional …

A Retrospective And Prospective Comparison Of Hungarian Children Who Have One Or Two Episodes Of Depression, Vanessa Panaite

USF Tampa Graduate Theses and Dissertations

Early onset depression is associated with high recurrence rates later in life. Recurrent depressive episodes during childhood may be particularly problematic, if additional episodes have a scarring effect that hinders healthy development. Distinguishing between first onsets and recurrences has been useful in understanding adult depression. This distinction has seldom been examined in pediatric depression, in part because it is difficult to enroll adequate samples of children with recurrent depression. We conducted archival analyses of carefully-diagnosed pediatric probands with depression first onset between ages of 4 and 12. Probands who reported one depressive episode (N = 435) were compared with probands …

Relations Among Classroom Support, Academic Self-Efficacy, And Perceived Stress During Early Adolescence, Krystle Kuzia Preece

USF Tampa Graduate Theses and Dissertations

The purpose of this study was to gain insight into the relations between support, academic self-efficacy, and stress during the transition into middle school. Research suggests that early adolescents experience an increase in stress across the middle school transition (e.g., Chung, et al., 1998), due to a mismatch between the individuals' developmental needs and the environment (Eccles et al., 1993). Stress has been found to be a risk factor for mental health disorders among adolescents (Grant et al., 2003). The current study examined if teacher and classmate support and academic self-efficacy served as external and internal resources for buffering stress …

Health-Promoting Behaviors And Subjective Well-Being Among Early Adolescents, Emily J. Shaffer-Hudkins

USF Tampa Graduate Theses and Dissertations

This study investigated the specific health-promoting behaviors employed by early adolescents (n = 246) and their subjective well-being (SWB) to provide an understanding of how mental and physical wellness relate in teens. Participants self-reported on their dietary habits, physical activity, sleep hygiene, safety habits, and attitudes toward substance use. A comprehensive assessment of SWB was also gathered (i.e., global life satisfaction, positive affect, and negative affect). The researcher hypothesized that each of the five health-promoting behaviors assessed in the current study would have significant, positive correlations with the SWB of early adolescents, in that youth who reported higher levels of …

Transition Experiences Of Adolescent Survivors Of Childhood Cancer: A Qualitative Investigation, Alana Delores Lopez

USF Tampa Graduate Theses and Dissertations

Adolescent survivors of childhood cancer are a growing population with unique needs as they face a combination of challenges associated with normal development and returning to life after treatment completion (Wakefield et al., 2010). One specific need identified in the research literature includes the effective delivery of transitional care and planning (Hewitt, Greenfield, & Stovall, 2005). It has been suggested that the provision of transition care and planning can help facilitate the shift from one phase of care to another and promote positive transition experiences (National Cancer Institute, 2008). The shift from off-treatment to post-treatment and school reintegration have been …

Links Between Parents' And Children's Levels Of Gratitude, Life Satisfaction, And Hope, Brenna D. Hoy

USF Tampa Graduate Theses and Dissertations

Positive psychology encourages a focus on identifying and promoting wellness in individuals rather than analyzing psychopathology. Although decades of research shows that mental illness is in part environmental and hereditary, little is known about the relationship between parental levels of positive emotions such as gratitude, life satisfaction, and hope, and their children's levels of the same constructs. This study utilized a past, present, and future framework of positive emotions to explore parental and child levels of gratitude, life satisfaction, and hope. This quantitative study analyzed correlations between self-reported levels of gratitude, life satisfaction, and hope among a sample of 153 …

An Investigation Into High Quality Leader Member Exchange Relationships And Their Relation To Followers' Motivation To Lead, Michael Rossi

USF Tampa Graduate Theses and Dissertations

This research further investigates the motivation to lead (MTL) construct and its antecedents. While existing research has investigated culture, personality, and direct experience as an antecedent to MTL, the indirect experience of observing an effective leader has not been studied. It was hypothesized that having an effective supervisor would be related to followers' leadership self efficacy and MTL. It was also hypothesized that this relationship would be moderated by the quality of the relationship between leader and follower. Little evidence was found supporting these hypotheses. In addition, the existing research into MTL has failed to establish the link between MTL …

Increasing Adolescents' Subjective Well-Being: Effects Of A Positive Psychology Intervention In Comparison To The Effects Of Therapeutic Alliance, Youth Factors, And Expectancy For Change, Jessica A. Savage

USF Tampa Graduate Theses and Dissertations

This study investigated the variance in subjective well-being (SWB) of early adolescents (n = 54) exposed to a positive psychology intervention aimed at increasing positive affect and life satisfaction as well as decreasing negative affect through intentional activities (e.g., gratitude journals, acts of kindness, use of character strengths, optimistic thinking). Understanding how to increase SWB among youth is important because of its associations with positive indicators of psychological and academic functioning. However, prior research is limited regarding interventions targeting SWB in youth and excludes the relation of common factors of therapeutic change. Based on the literature regarding therapeutic change, youth …
