Navigating Analytical Challenges In Clinical Trials Using The Multiverse Approach, Alexander O. Crenshaw, Nicole Pukay-Martin, Anne Wagner

Faculty Articles

Making decisions regarding data processing and analysis are crucial steps toward extracting insights from data in clinical trials. Trial registries like clinicaltrials.gov promote transparency about these decisions and encourage making them in advance. However, clinical studies often face decisions with multiple reasonable options outside the bounds of preregistration, such as when studies conduct post hoc analyses, deviate from preregistered plans, or simply were not preregistered. Additionally, even a priori decisions often have multiple reasonable options from which to choose. Methods that maximize transparency and minimize bias in such situations are needed. This paper advocates for applying a “multiverse” approach to …

Teachers And Administrators' Perceptions Of School Resource Officers, Shameka J. Duncan

Walden Dissertations and Doctoral Studies

School Resource Officers (SROs) play a significant role in middle and high schools in Metro Atlanta; however little research has included the perceptions of school administrators and teachers about their roles. The purpose of this descriptive qualitative study was to explore the perceptions of teachers and administrators regarding the roles of SROs and their perspectives on the practices that could enhance collaboration among these stakeholders in ensuring school safety. Informed by Gregory’s theory of perception, the study investigated how educators and administrators described their interactions with SROs. Data was gathered via semi-structured interviews with three teachers and three administrators and …

Determinants Of Clinical Supervisor Self-Efficacy In Substance Use Disorder Counseling, Victoria A. Nagel

Walden Dissertations and Doctoral Studies

Substance use disorder counselors face increasing challenges in responding to a growing and more severely affected population, often presenting with co-occurring mental health conditions and complex clinical needs. Clinical supervision plays a critical role in supporting counselor development, yet little is known about the factors that contribute to clinical supervisors’ self-efficacy in providing supervision for alcohol and drug counselors. The purpose of this quantitative correlational study was to examine whether years of counseling experience, years of substance use disorder (SUD) counseling experience, years as a clinical supervisor, professional counseling credentials, and supervisory credentials predicted self-efficacy among clinical supervisors. This study …

Community Reintegration Programs For Successful Reentry For Individuals Deemed Not Guilty By Reason Of Insanity, Joanna Baker

Walden Dissertations and Doctoral Studies

Very little research has been conducted on the institution of community reintegration programs for individuals deemed not guilty by reason of insanity (NGRI). In the United States, each state can determine the path for community reentry with the NGRI population. California has a strategic and supportive reentry program that requires services such as drug testing, individual therapy, and close monitoring. Other states, including North Carolina, do not have a reentry program in place for the NGRI population. No research exists comparing states with conditional release programs and states without these programs. Consistence in community reintegration programs among all states can …

Psychological Correlates Of Audiological And Self-Report Indicators Of Hyperacusis In Adults With Misophonia, Mercedes G. Woolley, Karen F. Muñoz, Guadalupe G. San Miguel, Anderson Clements, Julie M. Petersen, Michael P. Twohig

Psychology Student Research

Purpose:

Misophonia and hyperacusis are distinct sound sensitivity conditions that can co-occur and are linked to heightened emotional distress and impaired functioning. This study investigated the convergence between audiometric-based and self-reported indicators of hyperacusis and examined how each related to misophonia severity and psychological outcomes in adults with misophonia.

Method:

Participants (N = 60) completed self-report measures and underwent loudness discomfort level (LDL) testing.

Results:

Analyses revealed discrepancies between self-reported and LDL-defined hyperacusis, with no significant associations between LDL-based classifications and psychological or misophonia-related outcomes. In contrast, hyperacusis identified via a standardized self-report measure was significantly …

Utility Of The Wasi–Ii 2-Subtest Full Scale Iq For Identifying Impaired Cognitive Functions, Joseph J. Ryan, David S. Kreiner, Samuel T. Gontkovsky

Archives of Assessment Psychology

This study focused on how accurately the WASI–II 2FSIQ predicts the 4FSIQ. If two subtests can identify intellectual disability, a low score might prompt a switch to the WAIS–IV or WISC–V prior to completing the four WASI–II subtests. Participants were 94 individuals with psychiatric or neurological disorders (age M = 49.04 yrs, education M = 13.48 yrs) seem for clinical evaluation. The correlation between the 2FSIQs and 4FSIQs in the total sample was high, r(92) = .96, p < .001, but the former cannot be relied upon to predict 4FSIQs. It overestimated 4FSIQs in 69.1% of the cases, with only 50% of the 2FSIQs falling within + 3 points of the 4FSIQs. However, classification accuracy statistics indicated that the 2FSIQ effectively screened for the presence of intellectual disability. A 2FSIQ standard score cutoff of ≤ 79 yielded a high probability that the 4FSIQ was also at or below the cut score.

Potential Mediators In The Relationship Between Racial Identity And Neuropsychological Performance In A Retired Nfl Cohort, Claire Stafford, Charles Golden, Ryan Bennett

Archives of Assessment Psychology

Historically, Black Americans have consistently performed more poorly than White Americans on various neuropsychological tests, with debates surrounding the causes of these differences ranging from genetic to societal factors. These differences have been documented across various cognitive domains, including memory, attention, executive function, and processing speed. Findings from previous research suggest that individuals with higher levels of education and stable marital relationships tend to exhibit better cognitive functioning, while certain football positions are linked to differences in cognitive abilities. However, the specific effects of these factors on neuropsychological performance require further investigation. The present archival study was derived from a …

Incarceration’S Impact On Young Adults’ Psychological Development, Well-Being, And Reintegration Into Society, Monica Murrell

Walden Dissertations and Doctoral Studies

This qualitative phenomenological study explored how individuals who experienced incarceration during emerging adulthood understood and made meaning of their developmental, emotional, and psychosocial experiences. Emerging adulthood, defined as ages seventeen through twenty-five, is a critical developmental stage, and incarceration during this period may disrupt identity formation and emotional maturation. The purpose of the study was to examine the perspectives and coping mechanisms of individuals incarcerated during this stage to better understand how early adult imprisonment shapes trauma responses, identity development, and reintegration. Social learning theory served as the conceptual framework. Data was collected through interviews with six formerly incarcerated adults …

Daily Coping Strategies, Unmet Needs And Daily Health Outcomes Among Family Caregivers Of Persons Living With Alzheimer's Disease And Related Dementias, Henrietta Armah Bennett

ETDs from 2020-2029

Providing care for an individual with Alzheimer’s Disease and Related Dementias (ADRD) is considered the most stressful type of family caregiving that impacts caregivers’ health. More than one in five ADRD family caregivers report their overall health as poor to fair. These adverse health outcomes are often exacerbated when caregivers’ emotional, informational, and practical needs remain unmet throughout the caregiving trajectory. Numerous studies have shown that the ways in which caregivers cope to caregiving-related stressors significantly shape their health outcomes. Despite this evidence, a clear and consistent understanding of caregivers’ own appraisals of their unmet needs, coping strategies and mental …

Bare-Knuckled Public Service: Donald Rumsfeld’S Political Ideology Before The War On Terror, Chris Paskewich

Commonwealth Review of Political Science

Abstract Donald Rumsfeld (1932-2021) is perhaps most well known for being Secretary of Defense under President George W. Bush. However, he had a nearly fifty-year career in public and private sector work at the highest levels. Research into his political ideology, especially prior to his time under Bush, has never been undertaken. This article outlines Rumsfeld’s ideology for the first time, and shows it is a distinct strain of limited-government conservatism that I term “managerial conservatism.” Managerial conservatism aims to manage public resources well, maximize the gains from the public’s tax dollars, and make sure the federal government is only …

Texture Density Discrimination Is More Precise Than Number Discrimination, Frank H. Durgin, Nichole Suero Gonzalez , '27, P. Wen, A. C. Huk

Psychology Faculty Works

Density information is a possible primitive for the perception of numerosity. It has been argued, however, that the perception of numerosity is more precise than density perception at low numbers, whereas density is more precise for high numbers. An interpretive problem with the stimuli used to make those claims is that actual stimulus density was often mis-specified owing to an ambiguity regarding the idealized versus actual filled area. This ambiguity had the effect of underestimating density precision at low numerosities. Here we used a novel method of stimulus generation that allows us to accurately specify stimulus density independent of patch …

Reimagining Safety And Justice: Experiences Of And Resistance To Police Sexual Violence In New York City, Priscilla Bustamante

Dissertations, Theses, and Capstone Projects

In the era following both Black Lives Matter and #MeToo, police sexual violence (PSV) currently constitutes the second most commonly reported police complaint after excessive force. Police across the U.S. are caught for some form of sexual misconduct once every five days, with on-duty officers found to commit sexual assaults at more than double the rate of the general population. The gendered and racialized perpetration of sexual violence extends far beyond policing; however, it has been intensified within the masculine, militarized carceral structures designed to legally control and punish.

Accordingly, this dissertation utilizes an interdisciplinary, multi-method approach to offer what …

Somatosensory Cortex Responses To Illusory Touch In A Visual-Tactile Integration Task, Aditi Surendra Pawar

Dissertations, Theses, and Capstone Projects

Perceptual illusions arising from multisensory integration reveal how the brain constructs subjective experience from sensory input, and provide a powerful means of allowing the investigation of neural processes that track perceptual interpretation rather than physical stimulation alone. While visual illusions induced by auditory or tactile stimuli have been fairly well studied, the neural mechanisms underlying visually-induced illusory touch remain unclear. This study investigated whether illusory tactile perception engages the somatosensory cortex in a manner similar to veridical touch. Twenty healthy adults participated in an event-related functional magnetic resonance imaging (fMRI) study while performing a tactile numerosity judgment task. Each trial …

A Critical Lens On Emotions And Learning: Shame, Loneliness, And Alienation In Community College, Mike Rifino

Dissertations, Theses, and Capstone Projects

This dissertation explores how community college students make sense of and navigate their emotions related to learning. Community colleges are two-year public higher education institutions that primarily serve working-class and students of color, enrolling almost half of all current undergraduates in the United States, yet their experiences are rarely addressed by researchers. Drawing on critical theories (e.g., feminist politics of emotions, Black feminist/queer women of color theorizing), emotions in this study are conceptualized as socio-politically situated, shaped by institutions and ideologies distributed through power across intersecting social identities. Although emotion research in higher education has grown substantially in the past …

Derivation Of An Updated Brief Multivariable Prediction Model To Detect Panic-Related Anxiety In Emergency Department Patients With Cardiopulmonary Complaints, Sharon C. Sung, Felicia J. L. Ang, Arul Earnest, Leslie E. C. Lim, Shreshtha Jolly, Gilaine Rui Ng, A. John Rush, Marcus E. H. Ong

Research Collection School of Social Sciences

Background Patients with panic related-anxiety (i.e., panic attacks or panic disorder) frequently present to emergency departments (EDs) with cardiopulmonary complaints but are often undiagnosed, which can lead to recurrent visits and prolonged distress. This study aimed to derive a new symptom-based multivariable diagnostic prediction model to detect panic-related anxiety in ED patients with cardiopulmonary symptoms.Methods We conducted a single-blind prospective derivation study over 15 months in the ED of a major tertiary hospital in Singapore. Patients presenting with symptoms of palpitations, chest pain, dizziness, or difficulty breathing were assessed using the Structured Clinical Interview for DSM Disorders (SCID) to diagnose …

Examining The Effects Of Viewing Nature And Animal Smartphone Wallpapers On Affect, Behaviour, And Cognition: A Randomised Cross-Over Trial, Nadyanna M. Majeed, Nicole R. Y. Chen, Adalia Y. H. Goh, Meilan Hu, Kenneth J. J. Koh, Yuolmae H. G. Ang, Andree Hartanto

Research Collection School of Social Sciences

This study aims to investigate the effects of different smartphone lock screen wallpapers on weekly perceived well-being, procrastination, and productivity in young adults. Through a pre-registered within-subject experiment, 60 participants were exposed to three smartphone wallpaper conditions: nature, animal, and neutral (control). Each participant experienced each condition over three weeks, with the order of conditions counterbalanced. Using Frequentist and Bayesian analyses, we did not find any differences between conditions across the pre-registered confirmatory outcomes (i.e., life satisfaction, positive affect, negative affect, stress, productivity, and procrastination). Exploratory outcomes related to lock screen engagement, however, revealed some meaningful effects. Animal-themed smartphone wallpapers …

Situation Descriptions In Situational Judgment Tests: A Matter Of Including Trait-Relevant Situational Cues?, Philipp Schapers, Stefan Krumm, Filip Lievens, Jan-Philipp Freudenstein, Julian Schulze, Cornelius J. Konig

Research Collection Lee Kong Chian School Of Business

SJTs have traditionally been conceptualized as low-fidelity simulations of how respond to work-related situations. Yet, several studies demonstrated that situation descriptions were necessary to solve some SJT items, whereas they were not needed for other SJT items. So far, no solid support was found for various factors (e.g., item characteristics, presentation format, instructions, and content domain) that make some situation descriptions relevant and others irrelevant for responding to SJT items. Building on trait activation theory, we posit that trait-relevant situational cues serve as an ignored factor in SJT situation descriptions. Across two main studies (N-1 = 269, N-2 = 1,092), …

Perceptions Of Game-Based Assessments: The Role Of Test Takers' Occupational Background, Marie L. Ohlms, Klaus G. Melchers, Filip Lievens

Research Collection Lee Kong Chian School Of Business

Game-based assessments (GBAs) have become increasingly popular in personnel selection. However, research on perceptions of GBAs has yielded mixed results, highlighting the need to explore variables that may shape perceptions of GBAs. Therefore, we examined whether test takers' occupational background and other person-related characteristics (i.e., gender, age, video game usage, openness to experience) are associated with their perceptions of GBAs. N = 179 individuals from technical and social occupational backgrounds rated their perceptions of GBAs and non-gamified tests. We found that GBAs were generally rated more positively than non-gamified tests in terms of organizational attractiveness, behavioral intentions toward the organization, …

How Consistent Friendlike Conversation With Ai Companions Influences Our Attitudes And Perceptions Toward Ai: An Exploratory Experiment, Qi Hui Jerlyn Ho, Meilan Hu, Adalia Yin Hui Goh, Emma Jane Pragasam, Andree Hartanto

Research Collection School of Social Sciences

Despite skepticism and distrust in artificial intelligence (AI), it is increasingly integrated into daily life, with its potential benefits drawing interest. Yet little is known about the attitudinal and psychological effects of human–AI interactions, and whether consistent interactions with AI chatbots can change users’ attitudes and perceptions. Our within-subjects experiment (N = 52) investigated how five days of socially oriented, friendlike interactions with an AI chatbot, versus a journaling control, influenced changes in attitudes and perceptions of AI. Participants’ attitudes towards AI, trust, perceived empathy, anthropomorphism, animacy, likeability, perceived intelligence and safety, dependency, and exploratory well-being indicators were recorded. Results …

Investigating Sex Offenders’ Experience Of Being Registered As A Sex Offender, Stacey Mitchell-Swingle

Walden Dissertations and Doctoral Studies

In society, sex offenders are subject to unforeseen consequences of the sex offender registry. The purpose of this qualitative study was to investigate how the sex offender registry contributes to the mental distress of registered sex offenders and their concerns about recidivism. This study addressed a gap in understanding the sex offender registry experiences from the offender’s perspective. The research question addressed how adult male registrants describe their experiences of mental distress associated with registration and how they perceive registration as shaping their risk of reoffending. The theoretical framework was John Braithwaite’s reintegrative shaming theory, with a specific focus on …

Impact Of Burnout And Empathy On Correctional Officers’ Aggression, Sagan Ladd

Walden Dissertations and Doctoral Studies

Correctional officers experience persistent occupational stress that places them at elevated risk for burnout, which may negatively affect emotional functioning and increase aggression. Guided by general strain theory, this quantitative nonexperimental correlational study examined the relationships between burnout, empathy, and aggression among uniformed correctional officers working in U.S. jails and prisons. Participants (N = 58) completed the Maslach Burnout Inventory, the Interpersonal Reactivity Index, and the Buss–Perry Aggression Questionnaire–Short Form through an anonymous online survey. Simple and multiple linear regression analyses were conducted to answer three research questions. Results indicated that burnout significantly predicted aggression, F(1, 56) = 12.38, p < .001, R² = .18, such that higher burnout was associated with higher aggression scores. Empathy did not significantly predict aggression, F(1, 56) = 2.32, p = .133, R² = .04, though the relationship trended negatively. A multiple regression analysis revealed that burnout and empathy together significantly predicted aggression, F(2, 55) = 7.74, p = .001, R² = .19; however, burnout remained the only significant predictor when controlling for empathy. Additional analyses indicated that burnout significantly predicted all four facets of aggression: verbal aggression, physical aggression, anger, and hostility. These findings suggest that burnout plays a central role in aggression among correctional officers and highlight the importance of organizational and mental health interventions aimed at reducing burnout to promote staff well-being and institutional safety.

Psychologists’ Attitudes On Capital Punishment And Interpretation Of The American Psychological Association’S Ethics Code, Darya Baugh-Ruschman

Walden Dissertations and Doctoral Studies

When defendants are sentenced to death due to the nature of the crime, psychologists may be asked to participate in these cases, performing tasks such as conducting competency evaluations. Because the American Psychological Association (APA) Ethics Code states that psychologists cannot participate in activities that violate human rights, an ethical debate has emerged regarding whether they should participate in capital cases. The present study examined psychologists’ opinions on capital punishment and their interpretation of the APA Ethics Code, which does not specifically define what constitutes a violation of human rights. The theoretical framework for the study is the ethical decision-making …

Relationships Between The Dark Triad And Justification Of Morally Debatable Behaviors In College Students, Emma P. Paulson, Terry F. Pettijohn Ii

Psychology

The present study examined the relationship between Dark Triad personality traits and moral judgments in a sample of 68 undergraduate students recruited from psychology courses at a southeastern university. All participants volunteered through an online system and received course research credit for participation. Participants completed the Short Dark Triad Measure to assess levels of psychopathy, Machiavellianism, and narcissism, as well as the Revised Morally Debatable Behaviors Scale (MDBS-R), in a controlled laboratory setting. Individuals with strong psychopathic traits were predicted to report greater endorsement of morally debatable behaviors. Pearson correlation analyses were conducted to examine associations between Dark Triad traits …

The Perception Of Fentanyl’S Harm, Rachel Antenucci

ETDs from 2020-2029

While drug overdose deaths have generally decreased in the past year, close to 60,000 overdoses involving opioids occurred in 2024. The opioid crisis has lasted over two decades and is now in the fourth wave. The fourth wave has been characterized by overdoses resulting from fentanyl adulteration in the drug supply and polysubstance overdoses involving fentanyl. The purpose of the current study is to compare the perceived harm of fentanyl to other drugs of abuse and identify differences in the perceived harm of fentanyl between groups of people who use substances. An online survey was conducted across 15 states in …

The present study investigated differences in MMPI-2-RF scale scores between individuals with and without a history of mild traumatic brain injury (mTBI). The goal was to identify distinct psychosocial functioning patterns in individuals with mTBI. Archival outpatient sample of 147 adults aged 18 to 70 (M = 43.28, SD = 11.13) was utilized, comprising 65 participants with mTBI and 82 without TBI. Significant differences were observed across multiple MMPI-2-RF scales. The group with mTBI history exhibited higher levels of symptom overreporting, symptom validity concerns, emotional and internalizing dysfunction, somatic and cognitive complaints, and negative emotionality, as compared to the …

Unpacking Shared Pessimism Between Citizen And Bureaucracy: A Socio-Psychological Barrier To Public Service Reform In Indonesia, Reza Fathurrahman, Christoph Hoennige

BISNIS & BIROKRASI: Jurnal Ilmu Administrasi dan Organisasi

In this study, we examine the existence of a reciprocal pattern of performance bias shared between citizens and street-level bureaucrats, which we term as ‘shared pessimism’, assumed to implicate public service reform. Primary data were collected using surveys administered to 207 public service providers and 248 citizen recipients across six Indonesian public service agencies operated in two regional governments. Statistical analysis was then conducted to examine bureaucrats’ self-enhancing bias and their pessimistic view of citizen ratings, as well as to clarify citizens’ tendency to underrate the performance of bureaucrats in public service organizations. Our findings confirm pervasive internal pessimism amongst …
