Stigma And Disclosure Of Chronic Pain In Higher Education: A Qualitative Study, Jennifer K. Davenport

Graduate Theses and Dissertations

Students with chronic pain represent an overlooked population in higher education institutions, due to the barriers their conditions present and the stigma associated with chronic pain. There is existing research examines treatment of elderly populations and best practices for university students with disabilities, facing discrimination. This study sheds light on a gap in the existing research, where a niche population of students in chronic pain navigated disclosure issues and stigma in the academic environment. The purpose of the qualitative research study was to examine how anticipated or experienced stigma associated with chronic pain conditions influenced disclosure of chronic pain for …

An Interdisciplinary Study To Understand Treatment Seeking Behavior Among Female Survivors Of Anorexia Nervosa, Meaghan Victoria Tipton

Graduate Theses and Dissertations

This study was done to examine what psychosocial factors influence treatment seeking behavior among female survivors of eating disorders. This study uses a mixed methods survey consisting of open-ended item questions regarding treatment experience and social environment, and close-ended items to measure constructs from the Health Belief Model. Fourteen participants were recruited for this study to retrospectively detail their experiences of treatment during their eating disorder. All fourteen participants identified as Caucasian, thirteen identified as female, one identified with other gender, each with a history of medically diagnosed anorexia nervosa. The mean of age of current participants was 29.46, and …

Behavioral Effects Of Early Postpartum Offspring Removal In Rats, Jayda Melnitsky

Psychology

The maternal experience has been associated with alterations in behavior and in many different areas of the brain. Soon after giving birth and throughout the postpartum period, maternal behavior and care of offspring in particular have been shown to stimulate the dopaminergic system in postpartum women and rats alike. Around 15% of women who give birth develop postpartum depression (PPD), which has been associated with downregulation of dopamine activity. This experiment tested whether the removal of offspring immediately after parturition would alter the anxiety and depressive-like behavior of dams, as well as the expression of dopaminergic neurons. Adult female Sprague-Dawley …

The Effects Of Metformin On High-Fat Diet-Induced Neuroinflammation And Cognitive Impairment, Caleb Levine

Psychology

Chronic high-fat feeding is associated with neuroinflammation, cognitive impairment, and anxiety-linked behaviors in rats. Metformin, a popular treatment for type II diabetes, has been shown to attenuate metabolic dysregulation and weight gain associated with an obesogenic diet. We demonstrated that HFD caused elevated fasting blood glucose, glucose intolerance, and increased body weight without cognitive impairment or anxiety as measured by novel object recognition and open field testing. Further, we demonstrated that metformin did not produce cognitive impairment, which was a concern associated with its chronic use. Further work will elucidate the impact of chronic HFD and metformin treatment on molecular …

Streamlined Prevention And Early Intervention For Pediatric Anxiety Disorders: A Randomized Controlled Trial, Armando A. Pina, Nancy A. Gonzales, Gina L. Mazza, Heather J. Gunn, Lindsay E. Holly, Ryan D. Stoll, Julia Parker, Amanda Chiapa, Henry Wynne, Jenn-Yun Tien

Psychology Faculty Research and Publications

There is a need to optimize the fit between psychosocial interventions with known efficacy and the demands of real-word service delivery settings. However, adaptation of evidence-based interventions (EBI) raises questions about whether effectiveness can be retained. This randomized controlled trial (RCT) evaluated a streamlined package of cognitive, behavior, and social skills training strategies known to prevent and reduce anxiety symptom and disorder escalation in youth. A total of 109 youth (M_age = 9.72; 68% girls; 54% Latinx) at risk based on high anxiety were randomized to the streamlined prevention and early intervention (SPEI) (n = 59) or control (n …

Beyond Physical Entrainment: Competitive And Cooperative Mental Stances During Identical Joint-Action Tasks Differently Affect Inter-Subjective Neural Synchrony And Judgments Of Agency, Philip S. Cho, Nicolas Escoffier, Yinan Mao, Christopher Green, Richard C. Davis

Research Collection School Of Computing and Information Systems

Little work has examined how mental stance alone, apart from physical entrainment, affects between-participant neural synchrony during joint social interaction. We report the first findings on how cooperative and competitive mental stances, even during identical visuomotor joint-action tasks, result in distinct neural oscillatory signatures in low beta and theta band between-participant phase synchrony. Two participants jointly controlled a cursor and were instructed to either compete or cooperate to move it to one of three targets. The visuomotor output was identical for both the compete and cooperate conditions because participants were privately given the same target for experimental trials. Cooperation enhanced …

Patterns Of General- And Eating Disorder-Related Psychopathology In Relation To Weight Change In Treatment-Seeking Children, Anne Claire Grammer

Arts & Sciences Graduate Student Theses and Dissertations

Few studies have examined the compounded impact of general psychopathology and eating disorder (ED) psychopathology on weight change in youth with overweight/obesity (OW/OB). We characterized patterns of general psychopathology and ED psychopathology in children with OW/OB and examined the impact on weight change following family-based behavioral obesity treatment (FBT). Children (n=172) with OW/OB participated in 4 months of FBT. General psychopathology (i.e., anxiety, depression), ED psychopathology (i.e., shape concern, weight concern, loss of control (LOC) eating), and child percent overweight (%OW) were assessed at baseline. Latent profile analysis identified patterns of general and ED psychopathology at baseline. Multiple linear regression …

Body-Focused Repetitive Behaviors And Non-Suicidal Self-Injury: A Comparison Of Clinical Characteristics And Symptom Features, Abel S. Mathew, Taylor P. Davine, Ivar Snorrason, David C. Houghton, Douglas W. Woods, Han-Joo Lee

Psychology Faculty Research and Publications

Body-focused repetitive behaviors (BFRBs) and non-suicidal self-injury (NSSI) are recognized as distinct categories in the DSM-5. However, definitions and assessment of NSSI sometimes encompasses behaviors similar to BFRBs, and little data exist about their clinical differences. The current study examined clinical characteristics and symptom features associated with NSSI vs. BFRBs. The current sample included 1523 individuals who endorsed moderate to severe NSSI (n = 165) or BFRBs: hair pulling group (n = 102), skin picking group (n = 216), nail picking group (n = 253), nail biting group (n = 487), and cheek biting group …

Examining The Factor Structures Of The A-Des And Ptci To Identify Unique Predictors Of Ptsd Symptom Clusters In Maltreated Youth, Amanda Howard

UNLV Theses, Dissertations, Professional Papers, and Capstones

Research on childhood posttraumatic stress disorder (PTSD) has increased over the past decade. Youth who experience maltreatment are more likely to exhibit symptoms of PTSD. At present, the literature largely focuses on youth who have experienced general trauma or PTSD symptoms, while maltreated youth are understudied. To date, no studies have examined the psychometric properties of the Adolescent Dissociative Experiences Scale (A-DES) or the Posttraumatic Cognitions Inventory (PTCI) in a sample of maltreated youth. Predictors of childhood PTSD for maltreated youth remain unknown. The present study was the first research study to date to examine the factor structures of the …

The Relation Between Positive Stereotypes, Negative Stereotypes, And Discriminatory Behavior Toward Hispanic And White Populations, Aileen Ynez Lovitt

UNLV Theses, Dissertations, Professional Papers, and Capstones

Research examining positive stereotypes has suggested a possible connection between positive stereotype endorsement and prejudice. This literature, however, has not investigated the relation between positive and negative stereotypes endorsement. Additionally, the combined impact of positive and negative stereotype endorsement predicting prejudice or discrimination has not been considered. Two studies were conducted to address the limitations in past research and gain a better understanding of positive stereotypes relating to behaviors toward out-group racial groups using Hispanic and White participants. Positive stereotypes endorsement was hypothesized to be positively associated with negative stereotype endorsement and was expected to increase the predicted power of …

Dark Tetrad Responses To Moral Dilemmas, Kayli Wrenn

UNLV Theses, Dissertations, Professional Papers, and Capstones

The Dark Tetrad consists of four socially malevolent personality traits: psychopathy, sadism, narcissism, and Machiavellianism. The current study assessed the relationships among each dimension of the Dark Tetrad and moral decision making using sacrificial moral dilemma vignettes. Participants (n = 212 undergraduates) completed two measures of each of the four Dark Tetrad constructs then read a series of 16 sacrificial moral dilemma vignettes. These dilemmas manipulated whether the participant would personally perform the sacrifice and described either the disgusting or sad emotional consequences of the sacrifice. After each vignette, participants rated the moral rightness/wrongness, moral permissibility, and behavioral intention to …

Coping On The Fly: School Psychologists' Perceptions Of Cultural Competence, Jennifer Wynn

UNLV Theses, Dissertations, Professional Papers, and Capstones

The goal of this qualitative ethnographic study is to explore how school psychologists demonstrate multicultural competence (MC) when testing students for K-12 special education. As the population of the United States (US) becomes increasingly diverse, mental health professionals are encouraged to become culturally competent. Cultural competence is the ability to work with culturally and linguistically diverse populations; and being aware of stereotypes, biases and microaggressions. Cultural competence is taught within some psychology preparation programs; however, courses are often limited. Although cross-cultural competencies have been explored in clinical and counseling psychology, they have yet to be explored in the field of …

Hi God: An Autoethnography Of Loneliness In Graduate School, Grace Elisabeth Mertz

Dissertations and Theses @ UNI

I may have started college too early. My fifteen-year-old homeschooled mind could not have predicted the identity shift that higher education would demand of me. I did not expect academia to be filled with people who shared my background and beliefs, but I was, in many ways, unprepared for the way my Christianity would be challenged in the classroom and in my professors’ offices. After seven years of education within the structures of academia, I certainly have not lost my faith, but the way I think about, talk about, and practice it has tangibly changed. The questions I ask of …

Through Their Eyes: Exploring The Relationship Between College Females' Body Perceptions And Recreation Center Messaging, Sydney Leigh Ann Cindrich

Dissertations and Theses @ UNI

The study aimed to investigate the influence that recreation center promotional messaging had on college females’ body perceptions. Body perceptions among young adult females have been linked to mental health (McKay, 2013; Miner-Rubino, Twenge, & Fredrickson, 2002). Female participants 18 to 25 years of age (N = 137, Mage = 20.41) from a mid-sized, Midwestern university completed two separate body perception questionnaires. These questionnaires assessed body appreciation (functionality) and body shame (objectification). Participants were divided into three groups and shown a collage of recreation center messages that were portraying one of three conditions (a) body functionality, (b) self-objectification, or (c) …

Depressive Symptoms As A Moderator Of Diurnal Trends In Reward Seeking, Erick Albert William Rogers

UNLV Theses, Dissertations, Professional Papers, and Capstones

Anhedonia, a cardinal symptom of a major depressive episode, is the decreased motivation to seek rewards. Individuals with depressive symptoms tend to report reduced positive affect, a distal measure of reward motivation, and engage in less reward-motivated behavior (i.e., reward seeking). However, diurnal rhythms may also influence reward-seeking. Both self-reported positive affect and behavioral measures of reward-seeking increase from the morning to the afternoon and then decreased in the evening. Therefore, the aim of this study was to examine whether reward-seeking varied across time of day and whether anhedonia moderated variation. Overall, reward-seeking did not vary across time of day. …

A Temporal Information-Theoretic Model Of Suboptimal Choice, Paul J. Cunningham

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Humans and animals often make decisions not in their long-term best interest. In one example, called suboptimal choice, pigeons sacrifice food for food-predictive stimuli. The study of suboptimal choice can reveal insights into the role of reward-predictive stimuli in maladaptive decision-making that characterizes numerous behavioral disorders. However, there is currently little evidence that rats engage in suboptimal choice, thereby raising questions about the species-generality of suboptimal choice. According to the temporal information-theoretic model, developed in Chapter 2, suboptimal choice emerges when pigeons pay more attention to the bits of temporal information conveyed by food-predictive stimuli than the rate of food …

Crowdsourcing Hypothesis Tests: Making Transparent How Design Choices Shape Research Results, Justin F. Landy, Miaolei Jia, Isabel L. Ding, Domenico Viganola, Warren Tierney, Andree Hartanto

Research Collection School of Social Sciences

To what extent are research results influenced by subjective decisions that scientists make as they design studies? Fifteen research teams independently designed studies to answer five original research questions related to moral judgments, negotiations, and implicit cognition. Participants from two separate large samples (total N > 15,000) were then randomly assigned to complete one version of each study. Effect sizes varied dramatically across different sets of materials designed to test the same hypothesis: materials from different teams rendered statistically significant effects in opposite directions for four out of five hypotheses, with the narrowest range in estimates being d = -0.37 to …

Depletion Manipulations Decrease Openness To Dissent Via Increased Anger, Ming-Hong Tsai, Norman P. Li

Research Collection School of Social Sciences

We investigated a potential outcome of ego depletion manipulations and an importantfactor behind cooperative failure: a lack of openness to others’ dissenting opinions.Across five studies in a variety of task settings, we examined the effect of depletionmanipulations on openness to dissent and investigated two negative emotions as potentialmediators of this process: fatigue and anger. The results demonstrated a negative effect ofdepletion manipulations on openness to dissent through increased anger rather thanfatigue (Studies 1–5). In Studies 3 and 4, we also eliminated perceived trust towards a taskcounterpart as a significant mediator of the relationship between depletion manipulationsand openness to dissent. These …

Argumentative Synthesis Essay On Enhanced Interrogation Techniques, Gwendolyn D. Wheatley

The Downtown Review: An Interdisciplinary Journal Written and Peer-Reviewed by Mandel Honors College Students at Cleveland State University

This essay discusses enhanced interrogation techniques. For reference, enhanced interrogation techniques are interrogation techniques that involve “physically coercive interventions” (Duke & Puyvelde, 2017). The U.S. government supported these techniques after the attacks on September 11, 2001. This essay argues that enhanced interrogation techniques should not be used in interrogations because they are unethical, ineffective, and negatively impact the mental health of the interrogators using these techniques. Additionally, the essay references articles on the varied viewpoints as well as explains information on these interrogation techniques. Also, the essay argues that enhanced interrogation techniques encourage people to be cruel and inhumane. Moreover, …

Interactive Effect Of Maternal Activation And Disc-1 Knockout On Pup Preference Of Postpartum Rats, Barbara Bueno

UCARE: Research Products

The main purpose of the study was to find a three-way interaction between genotype, treatment and interacted subjects. Interestingly, and not expected, the KO*MIA rats spent more time with the pups compared to time spent with the male rat. This unexpected results from this study are evidence that there is a complex spectrum of behavioral symptoms due to genetics, environment and their interactive effect (Schwartzer et aI., 2013). For that reason, the interaction between genetics (DISCI) and environment (MIA) might be more complex than what is believed.

Mindfulness And Testing: An Exploration Of The Benefits Of Mindfulness Based Cognitive Meditation Practice On Test Anxiety, Anastasia Quirk

Graduate Theses, Dissertations, and Capstones

Test anxiety is a growing concern for students as it can negatively impact student performance. Mindfulness is a practice of focused breathing meditation intended to increase awareness of oneself and the present moment and decrease anxiety. With the recent increase in mindfulness practices in schools, this research examines the potential impact of mindfulness-based cognitive practice on anxiety levels, test anxiety, and standardized test scores through the use of the ACT standardized placement test, the TAI-G, a self-administered Test Anxiety Inventory, and the Biodot, a device measuring physiological indications of anxiety. Using analysis of variance and paired samples t-tests, a significant …

Evaluating The Diverted Attention Condition In A Trial-Based Functional Analysis, Kyle Frank

Thesis Projects

The diverted attention condition of a functional analysis is similar to the standard attention condition; however, instead of the therapist engaging in another task and ignoring the participant, the therapist provides attention to a confederate while diverting attention away from the participant. Contingent upon the occurrence of problem behavior, attention is diverted back to the participant. This study evaluated the diverted attention condition using a trial-based functional analysis format. Results of the standard functional analysis for both subjects were undifferentiated, whereas results of the trial-based functional analysis showed an attention function for one subject through the use of a diverted …

Express Yourself : A Study Of Expressive Writing And State Anxiety, Emerald Danielle Norman

Honors Theses

This study is under a larger study on the efficacy of psychological first aid compared to expressive writing as a crisis intervention method for individuals exposed to a traumatic event using a randomized controlled trial (RCT). Research has shown that expressive writing can be beneficial to improve the mental and physical health of patients (Gortner, Rude, & Pennebaker, 2006). Research has shown that the use of positive emotion and insight words through expressive writing can reduce state anxiety (Shen, Yang, Zhang, & Zhang, 2018). This study examined the effect of expressive writing on state anxiety by comparing the intervention with …

El Trastorno Por Déficit De Atención / Hiperactividad (Tdah) Según Apoderados De Escolares, Romina F. Ferretti Mg., Joaquín Gaete Dr.

The Qualitative Report

El diagnóstico de trastorno por déficit de atención/hiperactividad (TDAH) es el más frecuente en la población escolar de Chile. La búsqueda de ayuda profesional para esta condición es mayoritariamente gestionada por los apoderados de los escolares, quienes experimentan esta situación (y toman decisiones) a partir de su propia comprensión del TDAH. El objetivo de este estudio fue explorar la “situación” del apoderado TDAH, y en particular, cómo su experiencia se configura a partir de los discursos culturalmente disponibles acerca del TDAH. Mediante un análisis situacional (Clarke, 2005) se encontró que los apoderados toman cinco posiciones subjetivas a la hora de …

Job Knowledge Tests, Michelle Graef

Umbrella Summaries

What are job knowledge tests?

In an employment context, job knowledge tests are hiring tools that assess candidates’ knowledge of facts, principles, concepts, and other information that is important for performance of a job (Hunter, 1983). This knowledge falls into two general categories: (a) technical information and (b) the processes and judgmental criteria required to perform correctly and efficiently on the job (Hunter, 1983). Measures of job knowledge vary in the level of specificity of the content. Some measures are intended to test a candidate’s knowledge of specific content for a specific job, whereas other measures are designed to assess …

Effects Of Anodal Tdcs On Neural Correlates Of Cognitive Control In Mild-To-Moderate Traumatic Brain Injury, Nickolas A. Mertens

Psychology ETDs

Traumatic brain injury is a worldwide epidemic and currently there is no successful treatment to combat the cognitive deficits sustained from a mmTBI. The goal of this analysis is to determine if active tDCS paired with cognitive training can aid in an individual’s recovery on one specific consequence of mmTBI: cognitive control. To examine this novel treatment on cognitive control, EEG was recorded, and FM-theta activity collected from electrode FCz was analyzed. Three analyses were run to address the hypotheses of the present study: 1. A cluster analysis; 2. A series of repeated-measures ANOVAs; and 3. A series of multiple …

The Links Between Locus Of Control, Trauma History, And Death Anxiety In Cancer Patients, Joanna Mallary

Honors Scholar Theses

This thesis project used cross-sectional survey data from a larger longitudinal study of cancer patients' psychological adjustment to analyze correlations between a history of traumatic life experiences, personal control beliefs, and death anxiety in cancer patients who had been diagnosed between 1 and 3 years prior. Contrary to hypotheses, lifetime trauma history was not found to predict an external locus of control in patients but, in fact, was related to greater feelings of control over the course of their illness. However, results did confirm the hypothesis that control beliefs would be related in specific ways to anxiety about cancer-related death. …
