Further Validation Of The Realness Scale: Are Celebrity Worshipers Unreal?, Lynn E. Mccutcheon, Lillian Donahue, Joshua L. Williams, Sarah K. Nielson, Scott Peterson, Terry F. Pettijohn Ii

Psychology: Faculty Publications

We administered the Realness Scale (RS), Celebrity Attitude Scale (CAS), and the modified Authentic Living Subscale (ALS) from the Authenticity Scale (AS) to undergraduate students from four American institutions of higher learning. We sought to further validate the RS by showing that it correlated positively with the ALS and negatively with the CAS. We also hypothesized that African Americans would score lower than Whites on the RS. Our results supported the first hypothesis, but we found only weak or non-existent support for the other two hypotheses. Discussion focused on reasons why our latter two hypotheses yielded mostly negative results and …

The Impact Of Video-Taped Social Modeling On Alcohol Outcome Expectancies Of Young Adults And The Role Of Social Anxiety, Kyle Kevin Jackson

Graduate Theses and Dissertations

Alcohol outcome expectancies (AOEs) represent people’s ideas about the effects of alcohol (Fromme, 1993). Positive AOEs particularly have been identified as a potential risk factor for hazardous drinking (e.g., Brown et al., 1985). The exact mechanisms that modify AOEs are not fully understood. Further, people higher in social anxiety may be especially receptive to social modeling due to attentional bias shift towards others in social contexts (Rapee & Heimberg, 1997). The current study examined how social anxiety and social modeling associate with AOEs. It was hypothesized that 1) those in the social modeling treatment condition would have higher social anxiety-adjacent …

Distress In The Workplace: Characterizing The Relationship Of Burnout Measures To The Occupational Depression Inventory, Irvin Sam Schonfeld, Renzo Bianchi

Publications and Research

Burnout has been found to problematically overlap with depression. However, the generalizability of this finding remains disputed. This study examined burnout–depression overlap using the recently developed Occupational Depression Inventory (ODI) and two burnout measures, the Maslach Burnout Inventory (MBI) and the Copenhagen Burnout Inventory (CBI). The study involved two teacher samples employed in France (N = 1,450) and New Zealand (N = 492). We found the correlations of the ODI with (a) the MBI’s emotional exhaustion (EE) subscale and (b) the CBI to reach .80. An explanation of these high correlations based on content overlap in fatigue-related items was ruled …

Dysregulation Of Complement System In Neuropsychiatric Disorders: A Mini Review, Danny Perez Sierra, Ashutosh Tripathi, Anilkumar Pillai

Faculty, Staff and Student Publications

Complement system is one of the most important defense mechanisms of the innate immune system. In addition to their roles in immune regulation, complement proteins are also involved in neurodevelopment and adult brain plasticity. Complement dysregulation has been shown in neurodevelopmental disorders including schizophrenia and autism spectrum disorder as well as in mood disorders. A number of clinical as well as genetic studies suggest the role of complement proteins in the cortical thinning and excessive synaptic pruning frequently associated with schizophrenia. The changes in complement proteins are also associated with the pathophysiology of autism spectrum disorder, major depressive disorder and …

Pediatric Lung Transplantation For Covid-19: Unique Clinical And Psychosocial Barriers, Anupam Kumar, Gloria W Li, Justin M Segraves, Aladdein Mattar, Maheshwari Ramineni, Gabriel Loor, Puneet S Garcha

Faculty, Staff and Students Publications

BACKGROUND: SARS-CoV-2 infection in the age group of 0-17 years contributes to approximately 22% of all laboratory-confirmed SARS-CoV-2 infections. Fortunately, this age group has a lower death rate (0.5 per 100 000) that accounts for only 4% of the total deaths due to COVID-19. Despite the low mortality rate in the pediatric population, children of minority groups represented 78% of the deaths highlighting the existing disparities in access to health care.

METHODS: With the emergence of the more contagious COVID-19 variants and the relatively slow pace of vaccination among the pediatric population, it is possible to see more cases of …

Does Time Equal Money? Temporal Discounting And Self-Control: Insight Into The Rationality Of Personal Financial Decision-Making, Joshua Epstein

USF Tampa Graduate Theses and Dissertations

Exponential and hyperbolic intertemporal choice models have been widely investigated to measure an individual’s degree of impulsivity in behavioral economics. Hyperbolic discounting research identifies subject’s disproportionately high subjective value to immediate rewards, to the extent that it is not in their best interest. Furthermore, preference reversals have shown subjective value demonstrates an inversely relationship proportional to delay.

Investigation into whether visual representations influence conservative personal finance savings behavior was demonstrated in this study by presenting a multitude of visualizations before allocation of limited monetary resources. Evaluation of the neighbor effect was tested to determine whether comparing individuals to their peers …

Patterns Of Suicide And Self-Harm In Pakistan: A Retrospective Descriptive Study Protocol, Nargis Asad, Shahina Pirani, Summaiya Tariq, Asra Qureshi, Mohammad Zaman, Mustafa Aslam, Farhat Mirza, Murad M. Khan

Department of Psychiatry

Introduction: Suicide is a major global public health problem. Low-income and middle-income countries contribute 78% of all suicidal deaths. Pakistan, a South Asian country, lacks official statistics on suicides at national level. Statistics on suicide are neither collected nationally nor published in the annual national morbidity and mortality surveys. Medicolegal reports on suicides and self-harm are extremely rich and important source of information but greatly underused in Pakistan. We aim to examine the patterns of suicides and self-harm retrospectively in patients who were registered with medicolegal centres (MLCs) in Karachi, during the period January 2017 to December 2021.

Hiv And Early Life Stress On Neuroimaging And Risky Behavior, Paola Garcia Egan

Dissertations

This study examined the interactive effects of early life stress (ELS) and HIV on brain morphometry, diffusion-basis-spectrum-imaging (DBSI), risky decision-making, and sex-risk behavior. 122 people with HIV (PWH) and 113 people without HIV (PWoH), free of major psychiatric illness and neurological confounds, were stratified into high (≥ 3 events) vs. low (< 3 events) ELS [PWoH/low ELS (n = 57), PWoH/high ELS (n =56), PWH/low ELS (n = 43), PWH/high ELS (n = 79)] and underwent structural magnetic resonance imaging, DBSI, neuropsychological, and risky-behavior assessment; all PWH were virologically controlled. Compared to PWoH, PWH had smaller orbitofrontal cortex (OFC), parietal lobes, insula, caudate and anterior cingulate. No ELS effects were detected in volumetric measures. Significant interactions were found between HIV serostatus and ELS on the OFC and on cellularity of the inferior fronto-occipital fasciculus after multiple comparisons adjustment. Specifically, PWH/high ELS exhibited significantly smaller OFC and PWoH/high ELS show significantly larger OFC than the other groups. PWoH/high ELS exhibited higher DBSI cellularity (neuroinflammation proxy) of the inferior-occipital-fasciculus compared to PWoH/high ELS. Regardless of HIV status, executive function moderated the relationship between the OFC and sex-risk behavior such that individuals within the sample who performed above average on a measure of executive function and had a larger OFC reported fewer sex partners in past six months than individuals with smaller volumes. No interaction was found between HIV serostatus and ELS on risky behavior measures. Clustering analyses defined ELS subgroups in PWH that were determined by demographic characteristics, duration of infection, recent CD4+ T-cell count, nadir CD4+ T-cell count and high/low ELS.Even in PWH that are virologically controlled, without major current psychiatric comorbidities, there is evidence of a synergistic impact of ELS and HIV on OFC volumes. Higher volumes in the OFC were detrimental when associated with lower executive function scores or advantageous when associated with higher executive function. Findings suggest that ELS is associated with different brain signatures among PWoH and virally suppressed PWH. However, ELS was not directly associated with risky behaviors, and subgroups in PWH were characterized by demographic variables, past substance use and HIV clinical variables.

Qualitative Analysis Of A Twitter-Disseminated Survey Reveals New Patient Perspectives On The Impact Of Urinary Tract Infection, Marissa Valentine-King, Lindsey Laytner, Casey Hines-Munson, Kiara Olmeda, Barbara Trautner, Sheryl Justice, Christina Ching, Larissa Grigoryan

Faculty, Staff and Students Publications

Few studies have harnessed social media to explore patients’ experiences with urinary tract infection (UTI); therefore, we captured UTI experiences and future research suggestions through a Twitter-disseminated survey. The survey posed three qualitative questions inquiring about the impact of UTIs, greatest UTI management hurdle, and research suggestions. We also asked participants to rate how seriously others perceive UTIs and the importance of UTIs in their life (scale: 1–100 (highest)). The study period spanned from January to June 2021. Coding was performed in duplicate, followed by thematic analysis. Of 466 participants from 22 countries, 128 considered their UTIs recurrent (n …

How Things Take Up Space: A Grounded Theory Of Presence And Lived Space, Aleš Oblak, Asena Boyadzhieva, Jaya Caporusso, Borut Škodlar, Jurij Bon

The Qualitative Report

In cognitive science, it is unclear what precisely presence (both in the sense of objecthood and immersion) refers to in lived experience. The present study addresses the research question of what the relationship between presence is and lived space. A hundred and seventeen phenomenological interviews were conducted with 14 participants. We sampled their experience in a transdiagnostic manner. That is, we observed how the experience of presence changes both in circumstances appraised as positive (e.g., sexual intimacy) and negative (e.g., psychopathology). Our grounded theory suggests that presence is a phenomenon that is comprised of all available sensory knowledge, however, it …

Genome-Transcriptome-Functional Connectivity-Cognition Link Differentiates Schizophrenia From Bipolar Disorder, Jiayu Chen, Zening Fu, Juan R Bustillo, Nora I Perrone-Bizzozero, Dongdong Lin, Jose Canive, Godfrey D Pearlson, Julia M Stephen, Andrew R Mayer, Steven G Potkin, Theo G M Van Erp, Peter Kochunov, L Elliot Hong, Bhim M Adhikari, Ole A Andreassen, Ingrid Agartz, Lars T Westlye, Jing Sui, Yuhui Du, Fabio Macciardi, Faith M Hanlon, Rex E Jung, Jessica A Turner, Jingyu Liu, Vince D Calhoun

Faculty, Staff and Student Publications

BACKGROUND AND HYPOTHESIS: Schizophrenia (SZ) and bipolar disorder (BD) share genetic risk factors, yet patients display differential levels of cognitive impairment. We hypothesized a genome-transcriptome-functional connectivity (frontoparietal)-cognition pathway linked to SZ-versus-BD differences, and conducted a multiscale study to delineate this pathway.

STUDY DESIGNS: Large genome-wide studies provided single nucleotide polymorphisms (SNPs) conferring more risk for SZ than BD, and we identified their regulated genes, namely SZ-biased SNPs and genes. We then (a) computed the polygenic risk score for SZ (PRSSZ) of SZ-biased SNPs and examined its associations with imaging-based frontoparietal functional connectivity (FC) and cognitive performances; (b) examined the spatial …

Cerebral Blood Flow And Cardiovascular Risk Effects On Resting Brain Regional Homogeneity, Bhim M Adhikari, L Elliot Hong, Zhiwei Zhao, Danny J J Wang, Paul M Thompson, Neda Jahanshad, Alyssa H Zhu, Stefan Holiga, Jessica A Turner, Theo G M Van Erp, Vince D Calhoun, Kathryn S Hatch, Heather Bruce, Stephanie M Hare, Joshua Chiappelli, Eric L Goldwaser, Mark D Kvarta, Yizhou Ma, Xiaoming Du, Thomas E Nichols, Alan R Shuldiner, Braxton D Mitchell, Juergen Dukart, Shuo Chen, Peter Kochunov

Faculty, Staff and Student Publications

Regional homogeneity (ReHo) is a measure of local functional brain connectivity that has been reported to be altered in a wide range of neuropsychiatric disorders. Computed from brain resting-state functional MRI time series, ReHo is also sensitive to fluctuations in cerebral blood flow (CBF) that in turn may be influenced by cerebrovascular health. We accessed cerebrovascular health with Framingham cardiovascular risk score (FCVRS). We hypothesize that ReHo signal may be influenced by regional CBF; and that these associations can be summarized as FCVRS→CBF→ReHo. We used three independent samples to test this hypothesis. A test-retest sample of N = 30 healthy …

High School Course-Completion Trajectories And College Pathways For All: A Transcript Analysis Study On Elective Computer Science Courses, Hsun-Yu Chan, Ting-Lan Ma, Guan K. Saw, Yen-Ming Huang

Faculty Publications

Abstract: Whereas researchers regard high school math and science coursework as the best indicator of college readiness for students in the United States, computer science coursework and its relationship to college attendance, particularly for minoritized students, have not received due attention despite its root in the mathematical and scientific reasoning ability. We examined students’ high school course completion patterns across subjects and grade levels with a special focus on elective computer science courses and whether the coursework pattern transitions worked differently for minoritized students in Texas, USA. Latent profile analysis and latent transition analysis revealed multiple patterns of coursework, including …

Online-Delivered Over Staff-Delivered Parenting Intervention For Young Children With Disruptive Behavior Problems: Cost-Minimization Analysis, Justin B. Ingels, Phaedra S. Corso, Ron Prinz, Carol W. Metzler, Matthew R. Sanders

Faculty Publications

Background: High-prevalence childhood mental health problems like early-onset disruptive behavior problems (DBPs) pose a significant public health challenge and necessitate interventions with adequate population reach. The treatment approach of choice for childhood DBPs, namely evidence-based parenting intervention, has not been sufficiently disseminated when relying solely on staff-delivered services. Online-delivered parenting intervention is a promising strategy, but the cost minimization of this delivery model for reducing child DBPs is unknown compared with the more traditional staff-delivered modality.

Objective:This study aimed to examine the cost-minimization of an online parenting intervention for childhood disruptive behavior problems compared with the staff-delivered version of the …

Development Of The Mentalizing Network Structures And Theory Of Mind In Extremely Preterm Youth, Xiaoxue Fu Ph.D., Andy Hung, Aryanne D. De Silva, Tyler Busch, Whitney I. Mattson, Kristen R. Hoskinson, Hudson Gerry, Eric E. Nelson

Faculty Publications

Adolescents born preterm (<37 weeks of gestation) are at elevated risk for deficits in social cognition and peer relationships. Theory of Mind (ToM) is a complex form of social cognition important for regulating social interactions. ToM and the underlying mentalizing network continue to develop across adolescence. The present study recruited 48 adolescents (12–17 years old) who were either born extremely preterm (EPT; <28 weeks of gestation) or full-term (FT) at birth. Cortical thickness, gray matter volume and surface area were measured in four regions of the mentalizing network: the temporoparietal junction, anterior temporal cortex, posterior superior temporal sulcus and frontal pole (mBA10). We also assessed the adolescents’ performance on a ToM task. Findings revealed both group differences and group-by-age interaction effects in the gray matter indices within the temporal lobe regions of the mentalizing network. The EPT group also performed significantly worse than the FT group on the ToM task. The cortical structural measures that discriminated the EPT and FT groups were not related to ToM performance. These results highlight altered developmental changes in brain regions underlying mentalizing functions in EPT adolescents relative to FT controls.

Phubbing And Fear Of Missing Out As Mediators Between Problematic Social Media Use And Life Satisfaction Among Young Adults, Najeera Peer Meera Levai

Theses

Recent studies have shown certain risk indicators for young adults' decreased life satisfaction as a result of excessive social media use. However, few studies have looked at possible impact of problematic social media on life satisfaction, and less information is known about the mediating factors that contribute to this association. The purpose of the current study was to determine whether problematic social media use predicts life satisfaction among young adults. It also explored whether phubbing behaviour and fear of missing out might both serve as mediators in this relationship. A sample of 351 young adults (18–25, M_age = 19.74 …

Severe mental illnesses (SMI), including major depressive (MDD), bipolar (BD), and schizophrenia spectrum (SSD) disorders have multifactorial risk factors and capturing their complex etiopathophysiology in an individual remains challenging. Regional vulnerability index (RVI) was used to measure individual's brain‐wide similarity to the expected SMI patterns derived from meta‐analytical studies. It is analogous to polygenic risk scores (PRS) that measure individual's similarity to genome‐wide patterns in SMI. We hypothesized that RVI is an intermediary phenotype between genome and symptoms and is sensitive to both genetic and environmental risks for SMI. UK Biobank sample of N = 17,053/19,265 M/F (age = 64.8 …
