Effects Of Transcranial Direct Current Stimulation On Urge During Cue-Exposure To Body-Focused Repetitive Behaviors, Hannah Rebecca Wild

Theses and Dissertations--Psychology

Body-focused repetitive behaviors (BFRBs) are unnecessary, repetitive grooming behaviors linked to abnormalities in sensory and reward processing, as well as top-down inhibition. The left dorsolateral prefrontal cortex (dlPFC) is implicated in these processes and plays a key role in cravings among individuals facing addiction. Transcranial direct current stimulation (tDCS) targeting the left dlPFC shows promise in reducing craving for addictive substances. Despite phenomenological similarities between BFRBs and addictive disorders, no controlled studies have examined tDCS’s effect on BFRBs. This study used a randomized, double-blind design to examine whether a single session of anodal multifocal tDCS targeting the left dlPFC reduced …

Comparing Domain- And Facet-Based Models Of Personality Disorder: Incremental Predictive Validity And Model Fit, Alexandra Hines

Theses and Dissertations--Psychology

Personality disorders (PDs) have historically been conferred using a categorical diagnostic framework (i.e., present versus absent). However, recent research supports a transition toward dimensional models of PDs wherein personality traits are measured along a continuum. Some dimensional models contain personality domains only, whereas other models contain both personality domains and facets of each of those domains. The leading models of each type are the PD model in the eleventh edition of the International Classification of Diseases (ICD-11) and the Alternative Model of Personality Disorders (AMPD) in the fifth edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-5), respectively. …

A Mixed Method Investigation On The Effects Of Information And Motivation On Self-Regulation Skills And Fruit And Vegetable Consumption, Kristen Buford

Theses and Dissertations--Psychology

Introduction: The purpose of this research study is to understand the interplay between health information and health motivation on eating behaviors in African American emerging adults. Greater knowledge of nutrition is linked to healthier eating outcomes, but the motivations that individuals possess about their ability to improve their health also play a pivotal role. However, the joint effect of such constructs (i.e., information and motivation) on eating behaviors is unknown. Emerging adults are still developing their capacities to exercise their health autonomy, and this developmental period represents an opportunity to intervene before the onset of age-related chronic diseases in middle …

The Prevalence And Perception Of Maltreatment In Elite Dance Training, Cara Elena Guglielmino

Doctor of Psychology (PsyD)

Participation in elite dance training often requires navigating environments with heightened risk of physical and psychological maltreatment. This risk has historically been embedded and normalized through rigid pedagogical practices and professional expectations (Gregory & Interiano-Shiverdecker, 2021). Additional vulnerabilities for dancers include age of participation, training methodologies and culture, the dancer–instructor relationship, intensity and proximity of residential programs, and level of parental involvement. Existing research on elite dance training has predominantly focused on ballet-specific stressors, culture, and professional commitments using qualitative analysis. The present study examined the prevalence and perception of maltreatment, the psychological impact of harm, and identified implications for …

Exploring The Impact Of Pre-Assessment Rapport-Building On Children’S Evaluation Outcomes, Alyssa N. Springstead Knutz

Doctor of Psychology (PsyD)

Psychological assessment with children is vulnerable to inequities that arise from cultural mismatch, situational anxiety, and the interpretive nature of examiner judgement. This pilot study examined whether a brief, standardized pre-assessment sandtray activity could enhance children’s assessment experience and observational richness by supporting rapport prior to testing. Using a within-subjects, counterbalanced crossover design, 10 children (ages 7-10) completed two assessment sessions on separate days: one session included a 20-minute guided sandtray task immediately before testing and one session proceeded directly to testing. Quantitative outcomes included state anxiety (SAI-CH-6), general self-efficacy (GSE), and performance on brief standardized tasks (WJ-IV Math Fluency …

Let's Not Talk About Sex? Exploring Sexual Pain In Orthodox Jewish Women, Zehava Gros Schwartzblatt M.S.

Selected Full Text Dissertations, 2011-

Vaginismus, a genito-pelvic pain disorder characterized by involuntary muscle contraction that renders vaginal penetration painful or impossible, is estimated to affect between 1% and 7% of women worldwide (Laskowska & Gronowski, 2022). Although commonly conceptualized as a medical condition, growing evidence suggests that its etiology is significantly shaped by sociocultural and religious factors (Tugrul & Kabakci, 1997). In particular, belief systems that associate sexuality with immorality, sin, or shame (Cotter, 2015; Lewis et al., 2004), combined with limited sexual education, stigma, and misinformation (Nasserzadeh, 2015), may contribute to the development and maintenance of the disorder. These dynamics are especially salient …

The Adjustment Of Autistic First-Generation Students To Higher Education, Paris J. Cumba

Honors Undergraduate Theses

The purpose of the current study is to investigate how first-generation students on the autism spectrum adjust to higher education compared to their continuing generation and neurotypical peers through the lens of intersectionality. Previous research has studied how first-generation students and autistic students transition into college environments, but little research has explored how these identities intersect and affect college adjustment.

For this study, 189 undergraduate students completed a survey that measured different dimensions of college adjustment, such as academic motivation, self-efficacy, and current life satisfaction. ANOVA tests showed that there was no significant interaction between first-generation status and autism status …

Leadership and Strategy Faculty Publications

This study explores the relationship between employee grit and organizational resilience, focusing on perceptions from Filipino teachers during the COVID-19 pandemic. Utilizing a quantitative survey, data from 108 teaching faculty from a Southern Luzon university were analyzed using Spearman correlation to identify potential associations between these constructs. Findings reveal significant but weak to moderate correlations between dimensions of grit and facets of organizational resilience. Notably, adaptability to situations emerged as the most substantial grit component linked to organizational resilience, indicating its critical role in fostering organizational adaptability and planning strategies during uncertain times. The results suggest that individuals with high …

Exploring What Parents And Their Twice-Exceptional Children Need From The Mental Health System, Mehrnaz Mirhosseini M.S.

Selected Full Text Dissertations, 2011-

Twice-exceptional (2e) students, defined broadly as those with both high cognitive abilities and disabilities, have unique psychological needs. Many 2e students struggle in school and at home, and their abilities and disabilities tend to mask each other, making it more difficult to diagnose twice-exceptionality (Foley-Nipcon et al., 2013). Additionally, no gold-standard interventions have been identified (Foley-Nicpon & Candler, 2018). These factors and the relative obscurity of twice-exceptionalism can leave parents feeling helpless, confused, and isolated when seeking care for their 2e child. There is no research on which mental health interventions parents believe their 2e children need, as well as …

Real Talk: Piloting A Brief Digital Body Image Intervention For College Students, Logan Faith

Research Honors

The present study examines data from 20 participants who were randomly assigned to a brief digital body image intervention and a waitlist control group. The program, Real Talk, incorporated elements from several evidence-based approaches, namely affirming one’s values, making cognitive reappraisals, building body functionality, and self-compassion. The main outcome measures were body appreciation, functionality appreciation, self-kindness, and self-judgment. We hypothesized that Real Talk participants would experience greater increases in positive body image constructs and self-kindness and lower levels of self-judgment as compared to the waitlist control group. Data were analysed using nonparametric analyses due to the small sample size. Mann-Whitney …

Self-Compassion And Sexual Assault Victimization: A Systematic Review, Alexis A. Adams-Clark, Jerin Lee, Lucy W. Naughton, Anna Purcell, Ananya Sharma, Siena Candullo, Kelsey Sawyer, Prachi H. Bhuptani, Lindsay M. Orchowski

Student Publications [Scholarly]

Sexual assault survivors demonstrate substantial resilience, prompting calls for strength-based approaches to understanding recovery. One construct receiving increasing attention is self-compassion (i.e., treating oneself with kindness and understanding in the face of suffering), which may buffer against the negative mental health effects of assault victimization. The current systematic review synthesized data from 31 peer-reviewed studies examining self-compassion, sexual assault exposure, and mental health. Reported in accordance with Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) standards and registered in PROSPERO (CRD420250648494), the review included observational and experimental studies assessing sexual assault victimization and self-compassion across the lifespan. Most studies …

Startle Habituation And Vagally Mediated Heart Rate Variability Influence The Use Of Emotion Regulation Strategies, Xiao Yang, Fang Fang, Angela Ximena Babb

Psychology Faculty Publications

Emotion regulation refers to the processes through which people modulate their emotional experiences and expressions, and difficulties in these processes underpin many forms of psychopathology. According to the process model, emotion regulation encompasses five classes of strategies, commonly grouped into antecedent-focused strategies (e.g., cognitive reappraisal) and response-focused strategies (e.g., expressive suppression). These strategies involve both explicit and implicit processes, which can be objectively assessed using physiological indices. The present study examined the effects of startle habituation and vagally mediated heart rate variability (vmHRV) on the use of cognitive appraisal and suppression. Forty-nine college-aged participants were recruited, and their resting heart …

Maternal Child Maltreatment And Intimate Partner Violence: Effects On Perceptions Of Infant Temperment And The Mediating Role Of Emotion Regulation And Responsiveness, Jewelian N. Fairchild, G. Anne Bogat, Amy K. Nuttall, Alytia A. Levendosky, Joseph S. Lonstein, Maria Muzik

Psychology Faculty Publications

Purpose

Maternal adverse experiences, such as maltreatment in childhood and later intimate partner violence (IPV) during pregnancy, can disrupt the mother-child relationship and influence maternal perceptions of infant temperament. The present study explored how these adversities influence mothers’ views of their infants’ temperaments and examined the role of maternal emotion regulation and responsiveness to their infants as mediators of these relationships.

Methods

Using data from a longitudinal study of highly stressed, vulnerable women, 355 mothers retrospectively reported on their own childhood maltreatment, as well as their experiences of IPV and emotion regulation during pregnancy. Maternal responsiveness was coded using mother-infant …

Advancing Models Of Ptsd-Aud Comorbidity: Protocol For A Multimethod Framework Using Genetics And Ecological Momentary Assessment, Elizabeth A. Stinson, Samhita Lellapalli, Sage E. Hawn, Natalie Merrill, Lance M. Rappaport, Christina M. Sheerin, Vasiliki Michopoulos, Silviu-Alin Bacanu, Roseann E. Peterson, Abigail Powers, Ananda B. Amstadter

Psychology Faculty Publications

Background: Posttraumatic stress disorder (PTSD) and alcohol use disorder (AUD), which are moderately heritable, frequently co-occur and contribute to significant public health burdens, particularly among economically disadvantaged urban communities. There are noted sex differences in PTSD and AUD outcomes, with evidence suggesting women have heightened susceptibility to stress-related alcohol use. Preliminary PTSD-AUD ecological momentary assessment (EMA) findings support bidirectional associations across clinical outcomes. However, no studies to date have used PTSD-AUD comorbidity models as organizing frameworks to examine the temporal ordering and stability of within-person symptom dynamics underlying the maintenance or exacerbation of PTSD and AUD symptoms, including bidirectional and …

Establishing Hierarchical Classification Responding: Directly Trained And Emergent Responses, George H. Noell, Kristin A. Gansle, Hannah M. Sliman, Danielle M. De Lucia

Psychology Faculty Publications

Hierarchical classification responding (HCR) describes a collection of responses that require discrimination of logical relationships between stimuli based on their position in a categorical hierarchy. This study established HCR for a new hierarchy in young children through discrete trial instruction. Participants selected pictures corresponding to different hierarchical levels of categorization. We tested for the emergence of naming that matched the level of hierarchy presented, transformation of function, and class inclusion responding for the trained and novel stimuli. Correct responding to the target hierarchy was established and resulted in the emergence of class naming and transformation of function without direct instruction. …

Parental Psychological Distress And Perceived Child Externalizing Behaviors: Examining Mediators And Bidirectional Effects, Abigail J. Anderson, Christina M. Rodriguez, James M. Henson

Psychology Faculty Publications

Parental psychological distress is a commonly examined risk factor for the emergence of child problem behaviors, but the factors that contribute to that relationship—such as limited parental resources like greater social support and coping skills—have not been adequately explored, particularly with attention to potential bidirectional relations that incorporate child evocative effects. The current longitudinal study examined maternal and paternal psychological distress in relation to perceived child externalizing behaviors, considering parental resources as mediators within a bidirectional model. The sample included a racially and socioeconomically diverse group of 201 primiparous mothers and 151 fathers. Mothers and fathers reported their current psychological …

I Can't Stop: The Effects Of Psychological Climate For Overwork On Recovery Experiences, Jeffrey Drake Terry, Konstantin P. Cigularov

Psychology Faculty Publications

Recovery experiences are important for many health and well-being outcomes. One potential threat to an individual's recovery experiences in the workplace is psychological climate for overwork. The purpose of the present study was to examine the relationship between psychological climate for overwork and recovery experiences. Using a multi-wave research design (N = 202), we found that psychological climate for overwork had direct effects on psychological detachment and indirect effects on psychological detachment and relaxation through cognitive workaholism and work-recovery guilt. These results suggest that psychological climate for overwork may contribute to an individual's experience of cognitive workaholism and work-recovery guilt, …

Rude Awakening: An Examination Of The Incivility-Sleep Relationship Via Affect, Mallory A. Mccord, Gargi Sawhney, Nastassia M. Savage, Kristen M. Fisher

Psychology Faculty Publications

Despite the prevalence of incivility at work and the essential nature of sleep, study of this relationship is comparatively sparse in the organizational sciences literature. Further, although impaired sleep could logically impact how one interprets subsequent interpersonal interactions at work, the dominant approach is to study sleep as an outcome of perceived incivility. Therefore, we drew upon affective events theory, the affect-as-information hypothesis, and sleep physiology to argue that state affect, both positive and negative, can explain the relationship between perceived incivility and sleep quality in either direction. The hypotheses were tested using a between-subjects design with one-month time lags …

Examining The Factor Structure And Subgroup Invariance Of The Deliberate Denial Of Disordered Eating Behaviors Scale, Lindsay Howard, Sage Hawn, Kayla D. Pitchford, Riley Mcgrath, Aubri Farniok, Arturo Sesma, Kristin E. Heron

Psychology Faculty Publications

The denial, concealment, or omission of disordered eating behaviors has received limited attention in the eating disorder literature, partly due to the lack of reliable and valid measures. This study re-examined the factor structure of the Denial of Disordered Eating Behaviors Scale (DDEBS-12) and tested measurement invariance across gender identity, racial identity, and levels of disordered eating in a non-clinical undergraduate sample (N = 3285). Confirmatory factor analyses did not support the original unidimensional structure. Instead, a seven-item model assessing denial of dietary restriction demonstrated the best fit and was renamed the DDEBS-restriction. The revised scale showed good internal consistency …

From Molecules To Minds: Integrative Multi-Omics In Psychiatry, Hossein Abbasi, Sage E. Hawn, Arash Javanbakht, Soraya Seedat, Kyle Bourassa, Sinead M. Sinnott, Antonia V. Seligowski, Sian Hemmings, Nathan A. Kimbrel, Alicia K. Smith, Leslie Brick, Divya Mehta

Psychology Faculty Publications

Psychiatric disorders are biologically complex conditions arising from interactions across genomic, epigenomic, transcriptomic, proteomic, metabolomic, and metagenomic layers. Single-omics approaches rarely capture more than a fraction of the variance in complex conditions, underscoring the importance of integrative multi-omics frameworks. This mini-review summarizes key methodologies and their application in psychiatric research, with a focus on systems-level integration of genomic risk scores, transcriptomic networks, and neuroimaging data to advance biological understanding of disorders such as depression, schizophrenia, and Alzheimer’s disease. We also outline the infrastructural requirements for effective multi-omics research, including standardized biobanking, Laboratory Information Management Systems, adherence to FAIR data principles, …

Best Practices For Using Biological Data In Psychological Research, Sage E. Hawn, Sinead M. Sinnott, Alicia K. Smith, Kyle Bourassa, Leslie Brick, Sian Hemmings, Soraya Seedat, Arash Javanbakht, Lauren Smith, Antonia V. Seligowski, Nathan A. Kimbrel, Divya Mehta, Hossein Abbasi, Erika Wolf

Psychology Faculty Publications

Advances in statistical techniques for analyzing biological data have driven the need for larger sample sizes, which are ultimately made possible through team science efforts. Findings from these efforts have led to a significant shift in approaches to biological data collection over the past decade, from traditional approaches relying on single measures or assays collected by individual investigators in small lab-based studies to high-dimensional methodologies embedded within large cohorts or multi-site studies. These recent large scale consortium efforts necessitate careful consideration across the full data pipeline, from pre-data generation and sample collection to processing and statistical analysis, while addressing challenges …

A Real-Time Examination And Comparison Of Differentiation Among Suicidal Thinking And Affect Items In An Adolescent Sample, Elizabeth A. Edershile, Kinjal K. Patel, Annabelle M. Mournet, Richard T. Liu, Catherine R. Glenn, Evan M. Kleiman

Psychology Faculty Publications

Suicide risk assessments require individuals to differentiate among types of suicidal thoughts (e.g., passive vs. active); yet most research relies on aggregate metrics that obscure this differentiation. Indeed, more severe forms of suicidal thinking are thought to involve the simultaneous experience of multiple forms of thoughts at high intensities. The present study draws on concepts from the affect differentiation literature to (a) examine different ways to operationalize differentiation in suicidal thinking and (b) compare differentiation in suicidal thinking with differentiation in affect. Adolescents (N = 200) recently hospitalized for suicidal thoughts and behaviors completed a 28-day ecological momentary assessment …

Increasing Honest Statements In Young Children Through Presentation Of Social Contingencies And Emotionally Evocative Stimuli, George Noell, Kristin Gansle, Ella Wheelbarger, Hannah Sliman, Danielle De Lucia

Psychology Faculty Publications

Honesty is fundamental to interpersonal relationships and civil society. Although immediate contingencies often favor lying, many individuals respond honestly even when lying would be more efficient for contacting reinforcement. Across two experiments, we evaluated strategies for increasing honest responding by young children through exposure to social contingencies and emotionally evocative stimuli when material contingencies continued to reinforce lying. The stimuli were pictures of faces of children displaying happiness and sadness. The first experiment found that presession pairing of happy faces with honesty and sad faces with lying did not affect behavior; however, pairings combining verbal rule statements and faces contingent …

The Sleep, Inhibition, And Performance (Sip) Study: An Erp Investigation Of Sleep, Stress, And Response Inhibition In Early Childhood, Alivia Overbee

Master's Theses and Doctoral Dissertations

Background: Inhibitory control (IC) is fundamental to academic achievement and mental health, yet limited research examines how modifiable environmental factors influence neural substrates of IC in early childhood. Sleep regulation and adversity may shape IC development through experiential canalization processes. Objective: The Sleep, Inhibition, and Performance (SIP) study investigates how sleep characteristics, socioeconomic status (SES), and stress predict neural markers of inhibitory control in children aged 5-8 using event-related potentials (ERPs). Methods: Twenty children were enrolled in this study, which assessed sleep assessment via actigraphy, sleep diaries, and questionnaires. SES and stress were measured through caregiver reports. IC was assessed …

A Narrative Review Of Bertolotti's Syndrome: Etiology, Classification, Diagnosis, And Treatment, Matyas Abel Tsegaye, Andrea Muffly

Rehabilitation Sciences Faculty Publications

Bertolotti's syndrome is a congenital condition characterized by chronic low back pain stemming from a lumbosacral transitional vertebra (LSTV). Because the condition is frequently overlooked, patients often face years of delayed diagnosis before the true source of their pain is identified. Furthermore, current information regarding the biological origins and clinical management of the condition remain scattered. To address this knowledge gap, this narrative review aims to provide a comprehensive overview of Bertolotti’s syndrome by consolidating these disparate sources and suggesting new connections. We synthesize the latest understanding of this condition, ranging from its genetic origins to modern clinical management. We …

Eeg Signatures Of Motor Development In Early Childhood: A Systematic Review, Sonia Khurana, Ashwini Kulkarni, Thomas C. Bulea, Hunter J. Bennett

Rehabilitation Sciences Faculty Publications

Background

Early identification of motor developmental disorders is limited due to lack of objective neural markers that characterize typical neurodevelopmental patterns. This systematic review interprets and synthesizes existing evidence to propose a framework of EEG signatures associated with motor development in children aged 0-5 years, which may help inform future benchmarks for early assessment and intervention.

Methods

Following PRISMA guidelines, we searched published and gray literature across five databases between 2000 and 2025 (registered protocol). Included studies examined EEG during task-based, resting-state, or sleep studies linked to motor milestones, task performance, or standardized motor assessments. Study quality was assessed using …

Walking It Off: Habituation Of Gait At Virtual High Elevation, Kelly Poretti, Toby J. Ellmers, Christopher K. Rhea, Tiphanie Raffegeau

Rehabilitation Sciences Faculty Publications

Introduction: Fear and anxiety about falling can disrupt gait control, leading to activity restriction and increased fall risk in older adults. VR can be used to induce postural threat (e.g., by simulating high elevation settings) within a controlled environment, inducing fall-related anxiety and cautious gait (i.e. slower, shorter steps) in young and older adults. However, it is unknown how emotional and motor responses to VR postural threat habituate across time because existing studies feature short exposures (10 seconds or less). Before VR-induced postural threat can be translated into an intervention, it is critical to understand threat-related gait habituation across time. …

Occasional Papers on Religion in Eastern Europe

The article presents a comprehensive study of the phenomenon of professional burnout among military chaplains in Ukraine in the context of their personal experience of being in extreme (combat) conditions. The relevance of the problem is due to the prolonged impact of combat operations, high psycho-emotional stress, and the special role of military chaplains in the system of moral and psychological support for Ukraine's security and defense sector. The theoretical and methodological basis of the study was the concept of professional burnout by K. Maslach, the provisions of the person-centered approach, and the theory of personal experience. The empirical study …

Reward-Based Gamification: Evaluating Game Mechanics That Promote The Implementation Of Personal Device Security Measures, Leah Lynne Branstetter

Dartmouth College Master’s Theses

Many everyday computer users lack the cybersecurity knowledge and motivation necessary to secure their personal devices. To better understand these barriers, we conducted an initial study with nine participants who were asked to complete simple laptop security tasks, such as reviewing firewall settings. We found two primary challenges: participants were unfamiliar with basic security features, and many expressed low motivation to engage in security practices even after learning about them. To address the motivational barrier, we developed a beginner-friendly cybersecurity game designed to reward users for completing real device security tasks. We compared this reward-based game to a version of …
