Item Anxiety and Anxiety-Coping in Children's Picture Books(2023) Hui, Janisa; Wang, Cixin; Psychology; Digital Repository at the University of Maryland; University of Maryland (College Park, Md.)The contribution of this study is to provide an understanding of how picture books educate young children on the common experiences of anxiety. This qualitative study used thematic analysis to analyze 82 English children’s picture books for infants and young toddlers (0 to 5 years old) that were published in 2020. Picture books in this sample portray anxiety in a way that match with the clinical knowledge of childhood anxiety in terms of characterization and signs of anxiety. This study identified five major themes of anxiety-eliciting situations, namely schools, bad things happen, being alone, health and diversity. The findings of this study also include themes and patterns of coping strategies that were used by the protagonists; finding comfort, inhibiting emotions, solving problems, recognizing and expressing emotions and culturally-related strategies are the five themes that summarize the coping strategies found in this sample. Across all types of anxiety-eliciting situations, finding comfort is the most frequently presented coping strategy. This study holds implications for caregivers, teachers and clinicians, through which they can have an idea of how anxiety is presented in some recently published children’s picture books in their use of the books for educational or clinical purposes. Publishers may also take reference on the gaps noted in this study to diversify the content of anxiety-related picture books.Item Will there be a season? The impact of COVID-19 on anxiety within NCAA student athletes compared to non-athlete university students(2021) Peterman, Kirsten; Smith, J. Carson; Kinesiology; Digital Repository at the University of Maryland; University of Maryland (College Park, Md.)COVID-19 triggered psychological stress. College aged students and student athletes are among those vulnerable to mental health. The purpose of this study was to compare anxiety and potential moderators between student athletes and non-athlete students during the pandemic. Data were retrieved using survey methodology via Qualtrics. Student/athlete status was not related to anxiety (p=0.503). CF (p=<0.001), FFC (p=<0.001), and TFC (p=0.016) were associated with anxiety. There were no differences in coping between groups, however, greater TFC was related to greater anxiety in non-athlete students (p=< 0.001). Communication from AD’s (p=0.010) and teammates (p=0.033), as well as access to resources (p=0.036) were associated with anxiety in student athletes. Communication from coaches did not impact anxiety (p=0.545). Overall, anxiety during the pandemic was high. FFC may act as a protective factor, whereas TFC may worsen anxiety. Social support, access, and communication are crucial in times of uncertainty.Item THE STATE OF GRADUATE STUDENT MENTAL HEALTH IN THE UNITED STATES: ELEVEN YEARS AND 200,000 STUDENTS(2020) DeYoung, Kathryn Alyce; Leslie, Leigh A; Shackman, Alexander J; Family Studies; Digital Repository at the University of Maryland; University of Maryland (College Park, Md.)Graduate students are an essential part of the academic enterprise. Converging lines of evidence suggests that many graduate students experience high levels of emotional distress. Yet the true depth and breadth of this public health “crisis” has remained unclear. The present study used survey data collected from 187,427 American graduate students between 2008 and 2019 as part of the ACHA-NCHA II to demonstrate that moderate-to-severe emotional distress, psychiatric illness, and suicidality are common among graduate students. Remarkably nearly 1 in 3 students were diagnosed with or treated for one or more psychiatric disorders. Notably, every indicator of emotional distress and illness increased over the past decade, in some cases substantially, above and beyond contemporaneous shifts in demographic and institutional characteristics. This study represents the most comprehensive assessment to date, provides crucial information for refining research and policy, and sets the stage for efforts aimed at developing effective intervention strategies.Item Understanding Secondary Educators’ Knowledge of Mental Health and Their Perceptions of Their Role in Addressing Student Mental Health(2019) Ross, Ana-Sophia; Wang, Cixin; Psychology; Digital Repository at the University of Maryland; University of Maryland (College Park, Md.)Adolescents have significant unmet mental health needs and schools represent the most common place for youth to receive mental health services. Teachers are primarily responsible for recognizing and working with students with mental health needs. Scholarship has investigated teachers’ knowledge pertaining to signs and symptoms for mental illness and found that teachers report little confidence in their knowledge, and have difficulty accurately identifying students struggling with mental illness. Research has provided some insight into how teachers can promote positive mental health amongst their students but little is known about classroom educators’ perceptions about how they can address student mental health concerns. Thus, this qualitative study utilized thematic analysis to investigate 27 teacher/classroom educators’ perceptions about how they can help students who struggle with mental health problems. Five main themes emerged from the analysis: 1) school collaboration, 2) student support, 3) family involvement/family-school partnership, 4) school reform/systematic change, and 5) teacher professional development training. Additionally, the study also investigated educator’s knowledge of signs and symptoms of depression, anxiety, and eating disorders. Eighty-five percent of teachers were able to correctly identify depression from a vignette while all participants were able to identify an eating disorder from a vignette. This study provides insights about how to improve school-based mental health efforts, with specific attention to classroom-based educators’ role in the provision of services.Item Medial Frontal Theta Negativities (MFTN) as Predictors of Anxiety Sensitivity Treatment Response(2019) Ellis, Jessica Steward; Bernat, Edward M; Neuroscience and Cognitive Science; Digital Repository at the University of Maryland; University of Maryland (College Park, Md.)Anxiety is one of the most prevalent mental health problems around the world. Despite a number of widely available interventions, it can take weeks or months to see effects, and nearly half of individuals may not respond. In an effort to better understand response rates, a large body of evidence indicates the most consistent predictor of treatment outcomes is activity in the anterior cingulate cortex (ACC). Although activity in ACC can be measured by medial frontal theta event related potentials (ERPs) at a finer temporal resolution, these neurophysiological components have not been evaluated as predictors of treatment response. There is also a lack of research on the functional networks associated with ACC treatment prediction, despite implications for prefrontal engagement of cognitive control processes. The present study aimed to examine these gaps in the literature by using task-based electroencephalography (EEG) and medial frontal theta negativities (MFTN) as predictors of anxiety sensitivity treatment response. Using amplitude as well as functional connectivity measures (i.e., inter-channel phase synchrony), baseline MFTN (i.e., Theta-FN, Theta-N2) were assessed as predictors of treatment response at mid-treatment, 1-week post treatment, and 6 months post treatment. Subjects underwent a baseline EEG before completing three sessions of a computerized cognitive behavioral intervention. Contrary to the hypothesis, findings revealed MFTN amplitude did not predict treatment response. However, medial to lateral prefrontal theta phase synchrony demonstrated significant prediction effects, such that lower phase synchrony was associated with greater symptom improvement at mid-treatment, 1-week post treatment, and 6 months post treatment. This effect was specific to certain task conditions (i.e., gain feedback and go stimuli), as well as to the combined anxiety and depression treatment group. Results demonstrated accuracy and consistency of treatment prediction, as well as incremental validity after controlling for self-report measures. Finally, results provide additional support for a convergent medial frontal theta process, and suggest that low engagement of regulatory and proactive control mechanisms may be predictive of better response to cognitive behavioral interventions. This work represents a novel finding that may contribute to the improvement in treatment efficacy by serving as a target for future interventions and individualized treatment selection.Item THE RELATIONSHIP BETWEEN PSYCHOLOGICAL AGGRESSION VICTIMIZATION AND WOMEN’S ANXIETY: ALCOHOL USE AS A MODERATOR(2018) Mauss, Jasmine Marie; Epstein, Norman B; Family Studies; Digital Repository at the University of Maryland; University of Maryland (College Park, Md.)Intimate partner aggression is a serious concern, creating problematic issues among individuals and couples in romantic relationships. Psychological aggression, specifically, has shown to have detrimental effects on physical and mental health. Victims of such abuse often times find different ways to cope with the negative feelings that accompany being a recipient of partner aggression. The present study examines psychological aggression in relationships and its resulting associations with female partner anxiety symptoms. Further, the study explores alcohol use as a possible coping strategy and the way this tactic moderates the relationship between partner aggression and anxiety. Results from the study show that there was no significant association between partner aggression and anxiety symptoms and that alcohol use did not act as a moderator for this association. However, it was found that for two subtypes of psychological aggression (domination/intimidation and denigration) there were negative associations between aggression victimization and anxiety. Unlike the other subscales of psychological aggression (hostile withdrawal and restrictive engulfment), which showed no significance, higher levels of domination/intimidation, restrictive engulfment, and denigration were associated with lower levels of anxiety. Implications of the findings for future research and clinical practice are discussed.Item LANDSCAPES OF TENSION: EXPLORING NERVOUSNESS AND ANXIETY ON A MARYLAND PLANTATION(2018) BAILEY, MEGAN; Shackel, Paul A; Anthropology; Digital Repository at the University of Maryland; University of Maryland (College Park, Md.)This dissertation examines a late eighteenth- and early nineteenth-century plantation site, L’Hermitage, which is located in Frederick, Maryland, on what is now Monocacy National Battlefield. It considers how the interactions among and between the plantation owners, the Vincendière family, and their enslaved workers, in order to investigate how negotiations of power and supremacy can be read through spatial organization, material culture, and interpersonal relations. I refer to Denis Byrne’s (2003) use of the phrase “nervous landscape” to explore how a landscape and its occupants can be literally and figuratively nervous when absolute power fails and a heterogeneity and multiplicity of power and identities are introduced. That is, the disruption of homogeneity and hegemony breeds nervousness. Byrne uses this concept to explore racial tension; however, this project recognizes that anxiety can emerge from uneasiness around other structural factors. This research relies on multiple sources, including historical documents, artifacts, and archaeological features in order to explore how race, gender, class, religion, and nationality interacted on the plantation landscape. This work applies particular attention to how the power dynamics around these hierarchies played out within the nervous frame, mitigating or contributing to a nervous landscape. The dissertation also uses this framework to explore nervousness in the literal sense; how anxiety was a fundamental element of the colonial experience, and more broadly how emotion is an important aspect of the human experience that should be considered in archaeological interpretations of the past. This research is intended to contribute to the National Park Service’s goal of enhancing its interpretation of the larger context of the Civil War. Monocacy National Battlefield (MNB) is primarily valued for the battle that took place in 1864, and this is reflected in much of its current interpretation. However, MNB is committed to expanding this interpretation to situate the Civil War battle in its historical, social, political, economic, and geographical context. Research on plantation life, including topics such as agriculture, slavery, and racism, will contribute toward this goal. Furthermore, the results of my study can be useful in framing the way Monocacy discusses power dynamics and identity in the context of L’Hermitage.Item Understanding the anxiolytic effects of alcohol on the central extended amygdala in humans(2017) Kaplan, Claire Marjorie; Shackman, Alexander J; Psychology; Digital Repository at the University of Maryland; University of Maryland (College Park, Md.)The anxiety-reducing properties of alcohol are thought to contribute to development of alcohol dependence, particularly among individuals with anxiety disorders. Remarkably little is known, however, about the neural circuitry underlying anxiolytic effects of alcohol in humans. In a sample of 72 healthy adults, we employed the novel MultiThreat Countdown (MTC) task to investigate the dose-dependent consequences of acute alcohol intoxication (BAL range: 0.061 - 0.145%) during anticipation of certain or uncertain threat, compared to placebo. Focal analyses of the central extended amygdala revealed significant activation during threat in the right, but not left, hemisphere for both the central nucleus [Ce] and bed nucleus of the stria terminalis [BST]. Increasing BALs were associated with decreasing activation in right BST and self-reported fear/anxiety levels during threat. This effect did not differ between certain and uncertain threat. These results build upon converging lines of evidence and suggest involvement of BST in alcohol-induced anxiolysis.Item Social Influences of Error Monitoring(2016) Barker, Tyson Vern; Fox, Nathan A; Human Development; Digital Repository at the University of Maryland; University of Maryland (College Park, Md.)Adolescence is characterized by dramatic hormonal, physical, and psychological changes, and is a period of risk for affective and anxiety disorders. Pubertal development during adolescence plays a major role in the emergence of these disorders, particularly among girls. Thus, it is critical to identify early biomarkers of risk. One potential biomarker, the error-related negativity (ERN), is an event-related potential following an erroneous response. Individuals with an anxiety disorder demonstrate a greater ERN than healthy comparisons, an association which is stronger in adolescence, suggesting that pubertal development may play a role in the ERN as a predictor of anxiety. One form of anxiety often observed in adolescence, particularly among girls, is social anxiety, which is defined as anxiety elicited by social-evaluative contexts. In adults, enhancements of the ERN in social-evaluative contexts is positively related to social anxiety symptoms, suggesting that the ERN in social contexts may serve as a biomarker for social anxiety. This dissertation examined the ERN in and its relation with puberty and social anxiety among 76 adolescent girls. Adolescent girls completed a flanker task in two differentItem THE EFFECT OF INTOLERANCE OF UNCERTAINTY ON ATTENTION BIASES AS INDICATED BY PERFORMANCE ON THE EMOTIONAL STROOP AND DOT-PROBE TASK(2014) Norwood, Earta; MacPherson, Laura; Psychology; Digital Repository at the University of Maryland; University of Maryland (College Park, Md.)Anxiety disorders affect about 28.8% of the United States population at some time in their lifetime. Current theoretical models of anxiety disorders include cognitive constructs that are believed to play a crucial role in the etiology and maintenance of these disorders. Intolerance of uncertainty is one such cognitive construct, and it has been defined as a negative emotional, cognitive, or behavioral response to uncertain situations and events. Intolerance of uncertainty results in selective encoding and interpretation of information, such that people with high intolerance of uncertainty pay more attention to uncertain stimuli, go through greater elaborative encoding of uncertain information, have enhanced recollection of uncertain stimuli, and have a greater tendency to interpret such stimuli as threatening. Studies investigating processing biases in intolerance of uncertainty have used verbal-linguistic stimuli and have assessed biases during the interpretive and elaborative phase of information processing. The current study investigates intolerance of uncertainty as a moderator in the relationship between anxiety and information processing biases. Attention biases were assessed with the emotional Stroop task (using neutral words, threatening words, and words denoting uncertainty), and the dot-probe task (using photographs displaying faces with neutral or fearful expression). Contrary to our hypothesis, IU was not a moderator in the relationship between anxiety and automatic information processing biases. Additionally, we found no evidence of a relationship between IU and reaction times in the emotional Stroop and dot-probe task. Unexpectedly, the current study did not demonstrate a relationship between anxiety and automatic information processing biases.
