Pre-Exposure Prophylaxis (Prep) Uptake Among Black Men Who Have Sex With Men (Bmsm) In The Southern U.S., Oluwafemi Atanda Adeagbo, Sayward Harrison, Shan Qiao, Xiaoming Li

Faculty Publications

Black men who have sex with men (BMSM) living in the United States (U.S.) South are disproportionately affected by HIV and experience significant disparities in HIV incidence, access to HIV care, and prevention across ages and socio-economic statuses. The aim of this commentary is to critically review current literature on the state of PrEP use among BMSM in the U.S. South, including identifying barriers and facilitators to PrEP use in order to inform intervention development. Extant literature shows that despite the documented benefits of PrEP as an effective HIV-prevention method, its uptake among BMSM is limited across the U.S. South. …

Trigger Warnings In Psychology Classrooms?: Comparing Sexes From A Diverse Religious Institution, Jasmine Collard, Herbert W. Helm Jr

Faculty Publications

Sensitive, oftentimes unsettling topics are inherent, especially in psychology education (Boysen et al., 2018). Prior notification - also known as trigger warnings - to help students prepare for, or avoid, possibly disturbing, upcoming education topics (Boysen, 2017, p. 164) are being pushed for by college students on potentially disturbing content. We previously replication Guy A. Boysen’s “Trigger Warnings in psychology Classes: What Do Students Think?” and found that students from a diverse, religious institution had few significant differences, but, in general, the results from the two data sets were quite similar (Kim et al, 2020). To expand on this knowledge, …

Concurrent Associations Between Expressive Language Ability And Independence In Adolescents And Adults With Fragile X Syndrome, Leonard Abbeduto, Jessica Klusek, Julie Lounds Taylor, Nadia Abdelnur, Nicole Sparapani, Angela John Thurman

Faculty Publications

BACKGROUND: Few individuals with fragile X syndrome (FXS) successfully meet adult normative expectations in education, employment, peer relations, and habitation, although there is within-syndrome variability in this regard. The primary goal of this study was to determine whether expressive language skills contribute to the capacity for independent functioning in adulthood even after controlling for nonverbal cognitive ability. METHODS: Participants were 18- to 23-year-olds with FXS. Expressive language was assessed using the psychometrically validated Expressive Language Sampling (ELS) conversation and narration procedures. The language produced was transcribed and analyzed to yield measures of expressive vocabulary, syntax, and intelligibility. Parents concurrently completed …

Examining Associations Between Knowledge And Vaccine Uptake Using The Human Papillomavirus Knowledge Questionnaire (Hpv-Kq), Sayward Harrison, Valerie Yelverton, Yunfei Wang, Jan Ostermann, Laura J. Fish, Charnetta L. Williams, Lavanya Vasudevan, Emmanuel B. Walter

Faculty Publications

Objectives: Understanding the relationship between human papillomavirus (HPV) knowledge and vaccination behavior is important to inform public health interventions, yet few validated HPV knowledge scales exist. This study describes development of the Human Papillomavirus Knowledge Questionnaire (HPV-KQ) and its validation with parents residing in the southern United States (US). Methods: Drawing on previously published measures, we developed the 13-item HPV-KQ and administered the scale via Web-based survey to parents (N=1105) of adolescents ages 9 to 17 years. Dimensionality, internal consistency, model fit, and predictive validity were assessed. Results: The scale was bidimensional. One factor captured general HPV knowledge, and the …

Multilevel Modeling Of Interval-Contingent Data In Neuropsychology Research Using The Imertest Package In R, Richard S. Pond Jr., Matison W. Mccool, Brian A. Bulla

However, to fully capitalize on the wealth of data yielded by these designs, researchers have to understand the nature of multilevel data structures. The purpose of the present article is to describe some of the basic concepts and techniques involved in modeling multilevel data structures. In addition, this article serves as a step-by-step tutorial to demonstrate how neuropsychologists can implement basic multilevel modeling techniques with real data and the R package, lmerTest. R …

Eye Movement Desensitization And Reprocessing (Emdr) Practitioners’ Beliefs About Memory, Sanne T.L. Houben, Henry Otgaar, Jeffrey Roelofs, Ineke Wessel, Lawrence Patihis, Harald Merckelbach

Faculty Publications

Eye movement desensitization and reprocessing (EMDR) is a widely used treatment for posttraumatic stress disorder. The idea behind EMDR is that lateral eye movements may mitigate the emotional impact of traumatic memories. Given the focus on changing patients’ memories, it is important that EMDR practitioners have detailed knowledge about human memory. We explored beliefs and ideas about memory in samples of EMDR practitioners (Study 1: n = 12; Study 2: n = 41), students (Study 1: n =35; Study 2: n = 24), and researchers (Study 2: n = 30). All groups seemed to be aware of the fallibility of …

Cortical Microstructural Changes Associated With Treated Aphasia Recovery, Allen J. Chang, Janina Wilmonskoetter, Julius Fridriksson, Emilie R. Mckinnon, Lorelei P. Johnson, Alexandra Basilakos, Jens H. Jensen, Chris Rorden, Leonardo Bonilha

Faculty Publications

Objectives

To investigate the hypothesis that language recovery in post-stroke aphasia is associated with structural brain changes.

Methods

We evaluated whether treatment-induced improvement in naming is associated with reorganization of tissue microstructure within residual cortical regions. To this end, we performed a retrospective longitudinal treatment study using comprehensive language-linguistic assessments and diffusion MRI sequences optimized for the assessment of complex microstructure (diffusional kurtosis imaging) to evaluate the relationship between language treatment response and cortical changes in 26 individuals with chronic stroke-induced aphasia. We employed elastic net statistical models controlling for baseline factors including age, sex, and time since the stroke, …

Independent Contributions Of Structural And Functional Connectivity: Evidence From A Stroke Model, Lynsey M. Keator, Grigori Yourganov, Alexandra Basilakos, Argye E. Hillis, Gregory Hickok, Leonardo Bonilha, Chris Rorden, Julius Fridriksson

Faculty Publications

Altered functional connectivity is related to severity of language impairment in poststroke aphasia. However, it is not clear whether this finding specifically reflects loss of functional coherence, or more generally, is related to decreased structural connectivity due to cortical necrosis. The aim of the current study was to investigate this issue by factoring out structural connectivity from functional connectivity measures and then relating the residual data to language performance poststroke. Ninety-seven participants with a history of stroke were assessed using language impairment measures (Auditory Verbal Comprehension and Spontaneous Speech scores from the Western Aphasia Battery-Revised) and MRI (structural, diffusion tensor …

Faculty Publications

Objective: To evaluate associations between executive functioning and caregiver adherence monitoring with objective antihypertensive medication adherence over 24 months in adolescents with chronic kidney disease (CKD).

Methods: Adolescents (N = 97, 11–20 years old) with CKD taking antihypertensive medication and their caregivers were recruited from three pediatric nephrology clinics. At baseline, adolescents and caregivers reported on adolescents’ executive functioning and caregivers reported on their adherence monitoring. Antihypertensive medication adherence was objectively assessed via electronic monitoring at baseline and every 6 months after for 24 months. Associations between executive functioning, caregiver monitoring, and longitudinal adherence were evaluated with linear mixed models. …

Using Generalizability Theory And The Erp Reliability Analysis (Era) Toolbox For Assessing Test-Retest Reliability Of Erp Scores Part 1: Algorithms, Framework, And Implementation, Scott A. Baldwin, Peter E. Clayson, Kalie A. Carbine, Joseph A. Olsen, Michael J. Larson

Faculty Publications

The reliability of event-related brain potential (ERP) scores depends on study context and how those scores will be used, and reliability must be routinely evaluated. Many factors can influence ERP score reliability; generalizability (G) theory provides a multifaceted approach to estimating the internal consistency and temporal stability of scores that is well suited for ERPs. G theory's approach possesses a number of advantages over classical test theory that make it ideal for pinpointing sources of error in observed scores. The current primer outlines the G-theory approach to estimating internal consistency (coefficients of equivalence) and test-retest reliability (coefficients of stability). This …

Ugandan Adolescents’ Descriptive Gender Stereotypes About Domestic And Recreational Activities, And Attitudes About Women, Flora Farago, Natalie Eggum-Wilkens, Linlin Zhang

Faculty Publications

In Eastern Uganda, 201 adolescents aged 11- to 17-years old (48% girls; M_age = 14.62) answered close- and open-ended questions about gender stereotypes of domestic and recreational activities and gender-role attitudes about women’s behavior, rights, and roles. Adolescents answered questions such as “who is more likely to . . .?” assessing descriptive stereotypes (i.e., stereotype knowledge) and questions such as “is it ok for women to . . .?” assessing prescriptive stereotypes (i.e., stereotype endorsement) about gender roles. Data were analyzed via descriptive statistics, correlations, and thematic coding. Findings indicate that Ugandan adolescents were fairly egalitarian in some domains …

Investigating Developmental Changes In Scalp-To-Cortex Correspondence Using Diffuse Optical Tomography Sensitivity In Infancy, Xiaoxue Fu, John E. Richards

Faculty Publications

Significance: Diffuse optical tomography (DOT) uses near-infrared light spectroscopy (NIRS) to measure changes in cerebral hemoglobin concentration. Anatomical interpretations of NIRS data require accurate descriptions of the cranio-cerebral relations and DOT sensitivity to the underlying cortical structures. Such information is limited for pediatric populations because they undergo rapid head and brain development.

Aim: We aim to investigate age-related differences in scalp-to-cortex distance and mapping between scalp locations and cortical regions of interest (ROIs) among infants (2 weeks to 24 months with narrow age bins), children (4 and 12 years), and adults (20 to 24 years).

Approach: We …

A Qualitative Study Of Stress And Coping To Inform The Leads Health Promotion Trial For African American Adolescents With Overweight And Obesity, Mary Quattlebaum, Colby Kipp, Dawn Wilson-King, Allison Sweeney Ph.D.

Faculty Publications

The purpose of this study was to conduct in-depth individual interviews with 30 African American adolescents with overweight and obesity and their families (caregiver/adolescent dyads) to gain a better understanding of how to integrate stress and coping essential elements into an existing family-based health promotion program for weight loss. Interview data from 30 African American adolescents with overweight and obesity (Mage = 15.30 ± 2.18; MBMI%-ile = 96.7 ± 3.90) were transcribed and coded for themes using inductive and deductive approaches by two independent coders. Inter-rater reliability was acceptable (r = 0.70–0.80) and discrepancies were resolved to 100% agreement. The …

A Systematic Literature Review Of Sexual Harassment Studies With Text Mining, Amir Karami, Melek Yildiz Spinel, Nicole White, Kayla Ford, Suzanne Swan

Faculty Publications

Sexual harassment has been the topic of thousands of research articles in the 20th and 21st centuries. Several review papers have been developed to synthesize the literature about sexual harassment. While traditional literature review studies provide valuable insights, these studies have some limitations including analyzing a limited number of papers, being time-consuming and labor-intensive, focusing on a few topics, and lacking temporal trend analysis. To address these limitations, this paper employs both computational and qualitative approaches to identify major research topics, explore temporal trends of sexual harassment topics over the past few decades, and point to future possible directions in …

Age-Related Changes In Diffuse Optical Tomography Sensitivity Profiles In Infancy, Xiaoxue Fu, John E. Richards

Faculty Publications

Diffuse optical tomography uses near-infrared light spectroscopy to measure changes in cerebral hemoglobin concentration. Anatomical interpretations of the location that generates the hemodynamic signal requires accurate descriptions of diffuse optical tomography sensitivity to the underlying cortical structures. Such information is limited for pediatric populations because they undergo rapid head and brain development. The present study used photon propagation simulation methods to examine diffuse optical tomography sensitivity profiles in realistic head models among infants ranging from 2 weeks to 24 months with narrow age bins, children (4 and 12 years) and adults (20 to 24 years). The sensitivity profiles changed systematically …

S-Equol Mitigates Motivational Deficits And Dysregulation Associated With Hiv-1, Kristen A. Mclaurin, Sarah J. Bertrand, Jessica M. Illenberger, Steven B. Harrod, Charles F. Mactutus, Rosemarie M. Booze

Faculty Publications

Motivational deficits (e.g., apathy) and dysregulation (e.g., addiction) in HIV-1 seropositive individuals, despite treatment with combination antiretroviral therapy, necessitates the development of innovative adjunctive therapeutics. S-Equol (SE), a selective estrogen receptor beta agonist, has been implicated as a neuroprotective and/or neurorestorative therapeutic for HIV-1 associated neurocognitive disorders (HAND); its therapeutic utility for motivational alterations, however, has yet to be systematically evaluated. Thus, HIV-1 transgenic (Tg) and control animals were treated with either a daily oral dose of SE (0.2 mg) or vehicle and assessed in a series of tasks to evaluate goal-directed and drug-seeking behavior. First, at the genotypic level, …

Moderating Effects Of Parental Feeding Practices And Emotional Eating On Dietary Intake Among Overweight African American Adolescents, Mary Quattlebaum, Dawn K. Wilson-King, Allison M. Sweeney, Nicole Zarrett

Faculty Publications

This study examined the effects of parental feeding practices and adolescent emotional eating (EE) on dietary outcomes among overweight African American adolescents. Based on Family Systems Theory, it was hypothesized that parental feeding practices, such as parental monitoring and responsibility, would buffer the effects of EE on poor dietary quality, whereas practices such as concern about a child’s weight, restriction, and pressure-to-eat would exacerbate this relationship. Adolescents (N = 127; Mage = 12.83 ± 1.74; MBMI% = 96.61 ± 4.14) provided baseline data from the Families Improving Together (FIT) for Weight Loss trial and an ancillary study. Dietary outcomes (fruit …

Spiritual Well-Being - A Proactive Resilience Component: Exploring Its Relationship With Practices, Themes, And Other Psychological Well-Being Factors During The Covid-19 Pandemic In Cism-Trained First Responders, Justine Jaeger, Harvey J. Burnett Jr., Kristen R. Witzel

Faculty Publications

Research suggests spiritual resilience may ameliorate the negative effects of exposure to traumatic events among disaster mental health first responders. Our study examined the relationship between spiritual wellness and associated resilience factors among four groups of first responders (law enforcement, fire services, emergency medical services and 911 dispatchers) trained in Critical Incident Stress Management (CISM) during a global pandemic. Utilizing a mixed methods-survey with transcendental phenomenological design, data was collected from 107 participants with membership in the International Critical Incident Stress Foundation (ICISF) or the Michigan Crisis Response Association (MCRA). Participants completed the Connor-Davidson Resilience Scale, Spiritual Well-Being Scale-Shortened Version, …

Manipulations Of List Type In The Drm Paradigm: A Review Of How Structural And Conceptual Similarity Affect False Memory, Jennifer H. Coane, Dawn M. Mcbride, Mark J. Huff, Kai Chang, Elizabeth M. Marsh, Kendal A. Smith

Faculty Publications

The use of list-learning paradigms to explore false memory has revealed several critical findings about the contributions of similarity and relatedness in memory phenomena more broadly. Characterizing the nature of “similarity and relatedness” can inform researchers about factors contributing to memory distortions and about the underlying associative and semantic networks that support veridical memory. Similarity can be defined in terms of semantic properties (e.g., shared conceptual and taxonomic features), lexical/associative properties (e.g., shared connections in associative networks), or structural properties (e.g., shared orthographic or phonological features). By manipulating the type of list and its relationship to a non-studied critical item, …

Effects Of Psychosocial Support Interventions On Survival In Inpatient And Outpatient Healthcare Settings: A Meta-Analysis Of 106 Randomized Controlled Trials, Timothy B. Smith, Julianne Holt-Lunstad

Faculty Publications

We evaluated randomized controlled trials (RCTs) of psychosocial support interventions in inpatient and outpatient healthcare settings reporting survival data, including studies reporting disease-related or all-cause mortality. LOdds ratio (OR) and hazard ratio (HR) data were analyzed separately using random effects weighted models. Of 42,054 studies searched, 106 RCTs including 40,280 patients met inclusion criteria. Across 87 RCTs reporting data for discrete time periods, the average was OR = 1.20 (95% CI = 1.09 to 1.31, p < 0.001), indicating a 20% increased likelihood of survival among patients receiving psychosocial support compared to control groups receiving standard medical care. Among those studies, psychosocial interventions explicitly promoting health behaviors yielded improved likelihood of survival, whereas interventions without that primary focus did not. Across 22 RCTs reporting survival time, the average was HR = 1.29 (95% CI = 1.12 to 1.49, p < 0.001), indicating a 29% increased probability of survival over time among intervention recipients compared to controls. Among those studies, meta-regressions identified 3 moderating variables: control group type, patient disease severity, and risk of research bias. Studies with patients having relatively greater disease severity tended to yield smaller gains in survival time relative to control groups. In this meta-analysis, OR data indicated that psychosocial behavioral support interventions promoting patient motivation/coping to engage in health behaviors improved patient survival, but interventions focusing primarily on patients’ social or emotional outcomes did not prolong life. HR data indicated that psychosocial interventions, predominantly focused on social or emotional outcomes, improved survival but yielded similar effects to health information/classes and were less effective among patients with apparently greater disease severity.

Background

Hospitals, clinics, and health organizations have provided psychosocial support interventions for medical patients to supplement curative care. Prior reviews of interventions augmenting psychosocial support in medical settings have reported mixed outcomes. This meta-analysis addresses the questions of how effective are psychosocial support interventions in improving patient survival and which potential moderating features are associated with greater effectiveness.

Methods and findings

We evaluated randomized controlled trials (RCTs) of psychosocial support interventions in inpatient and outpatient healthcare settings reporting survival data, including studies reporting disease-related or all-cause mortality. Literature searches included studies reported January 1980 through October 2020 accessed from Embase, …

Cognitive Empathy And Longitudinal Changes In Temporo-Parietal Junction Thickness In Schizophrenia, Derin J. Cobia, Tatiana Karpouzian-Rogers, Julie Petersen, Lei Wang, Vijay A. Mittal, John G. Csernansky, Matthew J. Smith

Faculty Publications

Objective: Deficits in cognitive empathy are well-documented in individuals with schizophrenia and are related to reduced community functioning. The temporoparietal junction (TPJ) is closely linked to cognitive empathy. We compared the relationship between baseline cognitive empathy and changes in TPJ thickness over 24 months between individuals with schizophrenia and healthy controls. Methods: Individuals with schizophrenia (n = 29) and healthy controls (n = 26) completed a cognitive empathy task and underwent structural neuroimaging at baseline and approximately 24 months later. Symmetrized percent change scores were calculated for right and left TPJ, as well as whole-brain volume, and compared between groups. …

Roboethics In Covid-19: A Case Study In Dentistry, Wendy C. Birmingham, Yaser Maddahi, Maryam Kalvandi, Sofya Langman, Nicole Capicotto, Kourosh Zareinia

Faculty Publications

The COVID-19 pandemic has caused dramatic effects on the healthcare system, businesses, and education. In many countries, businesses were shut down, universities and schools had to cancel in-person classes, and many workers had to work remotely and socially distance in order to prevent the spread of the virus. These measures opened the door for technologies such as robotics and artificial intelligence to play an important role in minimizing the negative effects of such closures. There have been many efforts in the design and development of robotic systems for applications such as disinfection and eldercare. Healthcare education has seen a lot …

Moving Morality Beyond The In-Group: Liberals And Conservatives Show Differences On Group-Framed Moral Foundations And These Differences Mediate The Relationships To Perceived Bias And Threat., Brandon D. Stewart Phd, David S. M. Morris

Faculty Publications

Moral foundations research suggests that liberals care about moral values related to individual rights such as harm and fairness, while conservatives care about those foundations in addition to caring more about group rights such as loyalty, authority, and purity. However, the question remains about how conservatives and liberals differ in relation to group-level moral principles. We used two versions of the moral foundations questionnaire with the target group being either abstract or specific ingroups or outgroups. Across three studies, we observed that liberals showed more endorsement of Individualizing foundations (Harm and Fairness foundations) with an outgroup target, while conservatives showed …

The Benefit Of Gratitude: Trait Gratitude Is Associated With Effective Economic Decision-Making In The Ultimatum Game, Gewnhi Park, Charlotte Vanoyen-Witvliet, Jorge A. Barraza, Benjamin U. Marsh

Faculty Publications

The current research investigated the role of gratitude in economic decisions about offers that vary in fairness yet benefit both parties if accepted. Participants completed a trait/dispositional gratitude measure and then were randomly assigned to recall either an event that made them feel grateful (i.e., induced gratitude condition) or the events of a typical day (i.e., neutral condition). After the gratitude induction task, participants played the ultimatum game (UG), deciding whether to accept or reject fair offers (i.e., proposer: responder ratio $5:5) and unfair offers (i.e., proposer: responder ratios of $9:1, $8:2, or $7:3) from different proposers. Results showed that …

Early Rearing Conditions Affect Monoamine Metabolite Levels During Baseline And Periods Of Social Separation Stress: A Non-Human Primate Model (Macaca Mulatta), Elizabeth K. Wood, Natalia Gabrielle, Jacob Hunter, Andrea N. Skowbo, Melanie L. Schwandt, Stephen G. Lindell, Christina S. Barr, Stephen J. Suomi, James Dee Higley

Faculty Publications

A variety of studies show that parental absence early in life leads to deleterious effects on the developing CNS. This is thought to be largely because evolutionary-dependent stimuli are necessary for the appropriate postnatal development of the young brain, an effect sometimes termed the “experience-expectant brain,” with parents providing the necessary input for normative synaptic connections to develop and appropriate neuronal survival to occur. Principal among CNS systems affected by parental input are the monoamine systems. In the present study, N = 434 rhesus monkeys (233 males, 201 females) were reared in one of two conditions: as mother-reared controls (MR; …

Telepsychiatry Adoption Across Hospitals In The United States: A Cross-Sectional Study, Zhong Li, Sayward Harrison, Xiaoming Li, Peiyin Hung

Faculty Publications

Background: Access to psychiatric care is critical for patients discharged from hospital psychiatric units to ensure continuity of care. When face-to-face follow-up is unavailable or undesirable, telepsychiatry becomes a promising alternative. This study aimed to investigate hospital- and county-level characteristics associated with telepsychiatry adoption. Methods: Cross-sectional national data of 3475 acute care hospitals were derived from the 2017 American Hospital Association Annual Survey. Generalized linear regression models were used to identify characteristics associated with telepsychiatry adoption. Results: About one-sixth (548 [15.8%]) of hospitals reported having telepsychiatry with a wide variation across states. Rural noncore hospitals were less likely to adopt …

The Impact Of Short Sleep On Food Reward Processes In Adolescents, Kara Mcrae Duraccio, K. N. Krietsch, N. Zhang, C. Whitacre, T. Howarth, M. Pfeiffer, D. W. Beebe

Faculty Publications

Short sleep has been linked to adolescent obesity risk, but questions remain regarding the dietary mechanisms by which this occurs. We tested whether mildly shortening sleep influences how rewarding and appealing healthy adolescents find several kinds of foods. Eighty-eight healthy adolescents completed a within-subjects crossover sleep experiment comparing 5 days of Short Sleep (6.5 hour sleep opportunity) vs. 5 days of Healthy Sleep (9.5 hour sleep opportunity). Following each condition, adolescents completed measures of food appeal and reinforcing value of food across five food types: sweets/desserts, fruits/vegetables, lean meats/eggs, fast food entrees, and processed snacks. Adolescents averaged 2.2 hours/night longer …

A Commentary On Establishing Norms For Error-Related Brain Activity During The Arrow Flanker Task Among Young Adults, Peter E. Clayson, Emily S. Kappenman, William J. Gehring, Gregory A. Miller, Michael J. Larson

Faculty Publications

We suggest that a large data set for the error-related negativity (ERN) and error positivity (Pe) components of the scalp-recorded event-related brain potential (ERP) recently published as normative is not ready for such use in research and, especially, clinical application. Such efforts are challenged by an incomplete understanding of the functional significance of between-person differences in amplitudes and of nuisance factors that contribute to amplitude differences, a lack of standardization of methods, and the use of a convenience sample for the potentially normative database. To move ERPs toward standardization and useful norms, we encourage more research on the meaning of …

Structural Templates For Imaging Eeg Cortical Sources In Infants, Christian O'Reilly, Eric Larson, J. E. Richards, Mayada Elsabbagh

Faculty Publications

Electroencephalographic (EEG) source reconstruction is a powerful approach that allows anatomical localization of electrophysiological brain activity. Algorithms used to estimate cortical sources require an anatomical model of the head and the brain, generally reconstructed using magnetic resonance imaging (MRI). When such scans are unavailable, a population average can be used for adults, but no average surface template is available for cortical source imaging in infants. To address this issue, we introduce a new series of 13 anatomical models for subjects between zero and 24 months of age. These templates are built from MRI averages and boundary element method (BEM) segmentation …
