Description
Anxiety and depression are among the most prevalent disorders in youth, with prevalence rates ranging from 15% to 25% for anxiety and 5% to 14% for depression. Anxiety and depressive disorders cause significant impairment, fail to spontaneously remit, and have been prospectively linked to problematic substance use and legal problems in adulthood. These disorders often share a high-degree of comorbidity in both clinical and community samples, with anxiety disorders typically preceding the onset of depression. Given the nature and consequences of anxiety and depressive disorders, a plethora of treatment and preventative interventions have been developed and tested with data showing significant pre to post to follow-up reductions in anxiety and depressive symptoms. However, little is known about the mediators by which these interventions achieve their effects. To address this gap in the literature, the present thesis study combined meta-analytic methods and path analysis to evaluate the effects of youth anxiety and depression interventions on outcomes and four theory-driven mediators using data from 55 randomized controlled trials (N = 11,413). The mediators included: (1) information-processing biases, (2) coping strategies, (3) social competence, and (4) physiological hyperarousal. Meta-analytic results showed that treatment and preventative interventions reliably produced moderate effect sizes on outcomes and three of the four mediators (information-processing biases, coping strategies, social competence). Most importantly, findings from the path analysis showed that changes in information-processing biases and coping strategies consistently mediated changes in outcomes for anxiety and depression at both levels of intervention, whereas gains in social competence and reductions in physiological hyperarousal did not emerge as significant mediators. Knowledge of the mediators underlying intervention effects is important because they can refine testable models of treatment and prevention efforts and identify which anxiety and depression components need to be packaged or strengthened to maximize intervention effects. Allocating additional resources to significant mediators has the potential to reduce costs associated with adopting and implementing evidence-based interventions and improve dissemination and sustainability in real-world settings, thus setting the stage to be more readily integrated into clinical and non-clinical settings on a large scale.

Description
The goal of our study is to identify socio-economic risk factors for depressive disorder and poor mental health by statistically analyzing survey data from the CDC. The identification of risk groups in a particular demographic could aid in the development of targeted interventions to improve overall quality of mental health in the United States. In our analysis, we studied the influences and correlations of socioeconomic factors that regulate the risk of developing Depressive Disorders and overall poor mental health. Using the statistical software STATA, we ran a regression model of selected independent socio-economic variables with the dependent mental health variables. The independent variables of the statistical model include Income, Race, State, Age, Marital Status, Sex, Education, BMI, Smoker Status, and Alcohol Consumption. Once the regression coefficients were found, we illustrated the data in graphs and heat maps to qualitatively provide visuals of the prevalence of depression in the U.S. demography. Our study indicates that the low-income and under-educated populations who are everyday smokers, obese, and/or are in divorced or separated relationships should be of main concern. A suggestion for mental health organizations would be to support counseling and therapeutic efforts as secondary care for those in smoking cessation programs, weight management programs, marriage counseling, or divorce assistance group. General improvement in alleviating poverty and increasing education could additionally show progress in counter-acting the prevalence of depressive disorder and also improve overall mental health. The identification of these target groups and socio-economic risk factors are critical in developing future preventative measures.

Description
In Memory of an Emily is a piece of creative nonfiction and a short film that together detail the author’s experience with mental illness in the collegiate environment. In its 45 pages, Jackman begins to detail the realities of living with depression, anxiety, and anorexia nervosa. The piece includes five sections of writing, including a preface and four portions describing freshman to senior year. Each section endeavors to explore simplistic and purposefully cliché events common in young adult/collegiate life and juxtapose the banal nature of these events with the experience of the mentally ill. Her story endeavors to explore the emotional truths of pain and suffering, revealing that beneath her tender façade lies a very different existence, one tangled in eating disorders, panic attacks, and overwhelming sadness. While maintaining a story-like quality traditional to creative non-fiction, Jackman ventures to warn with a cautionary tale of pathologizing abnormality and exploring the long lasting effects of childhood trauma. Weaving careful storytelling into an exploration of the mentally ill mind, Jackman keeps the reader both terrifyingly close and far away, whispering painful secrets and then desperately running away with the truth. She speaks frankly of all aspects of life, ranging from far more mundane events, such as break ups and college rejection letters, to complicated issues, such as the suicide of her grandfather and her admission into an eating disorder facility. The author attempts to establish a balanced rapport with the reader, recognizing the need to maintain distance and elicit emotion simultaneously. Jackman writes In Memory of an Emily as a heartbreaking but authentic tale, playing with stream of consciousness and paralyzing emotional description. She opens the door and invites the reader into her mind so as to share in the physical and emotional discomfort of the storyteller, but then promptly slams the door once inside.

Description
Campaign finance regulation has drastically changed since the founding of the Republic. Originally, few laws regulated how much could be contributed to political campaigns and who could make contributions. One by one, Congress passed laws to limit the possibility of corruption, for example by banning the solicitation of federal workers and banning contributions from corporations. As the United States moved into the 20th Century, regulations became more robust with more accountability. The modern structure of campaign finance regulation was established in the 1970's with legislation like the Federal Election Campaign Act and with Supreme Court rulings like in Buckley v. Valeo. Since then, the Court has moved increasingly to strike down campaign finance laws they see as limiting to First Amendment free speech. However, Arizona is one of a handful of states that established a system of publicly financed campaigns at the state-wide and legislative level. Passed in 1998, Proposition 200 attempted to limit the influence of money politics. For my research I hypothesized that a public financing system like the Arizona Citizens Clean Elections Commission (CCEC) would lead to Democrats running with public funds more than Republicans, women running clean more than men, and rural candidates running clean more than urban ones, and that Democrats, women, and rural candidates would win in higher proportions than than if they ran a traditional campaign. After compiling data from the CCEC and the National Institute on Money in State Politics, I found that Democrats do run with public funds in statistically higher proportions than Republicans, but when they do they lose in higher proportions than Democrats who run traditionally. Female candidates only ran at a statistically higher proportion from 2002 to 2008, after which the difference was not statistically significant. For all year ranges women who ran with public money lost in higher proportions than women who ran traditionally. Similarly, rural candidates only ran at a statistically higher proportion from 2002 to 2008. However, they only lost at higher proportions from 2002 to 2008 instead of the whole range like with women and Democratic candidates.

Description
The current study utilized data from two longitudinal samples to test mechanisms in the relation between a polygenic risk score indexing serotonin functioning and alcohol use in adolescence. Specifically, this study tested whether individuals with lower levels of serotonin functioning as indexed by a polygenic risk score were vulnerable to poorer self-regulation, and whether poorer self-regulation subsequently predicted the divergent outcomes of depressive symptoms and aggressive/antisocial behaviors. This study then examined whether depressive symptoms and aggressive/antisocial behaviors conferred risk for later alcohol use in adolescence, and whether polygenic risk and effortful control had direct effects on alcohol use that were not mediated through problem behaviors. Finally, the study examined the potential moderating role of gender in these pathways to alcohol use.
Structural equation modeling was used to test hypotheses. Results from an independent genome-wide association study of 5-hydroxyindoleacetic acid in the cerebrospinal fluid were used to create serotonin (5-HT) polygenic risk scores, wherein higher scores reflected lower levels of 5-HT functioning. Data from three time points were drawn from each sample, and all paths were prospective. Findings suggested that 5-HT polygenic risk did not predict self-regulatory constructs. However, 5-HT polygenic risk did predict the divergent outcomes of depression and aggression/antisociality, such that higher levels of 5-HT polygenic risk predicted greater levels of depression and aggression/antisociality. Results most clearly supported adolescents’ aggression/antisociality as a mechanism in the relation between 5-HT polygenic risk and later alcohol use. Deficits in self-regulation also predicted depression and aggression/antisociality, and indirectly predicted alcohol use through aggression/antisociality. These pathways to alcohol use might be the most salient for boys with low levels of socioeconomic status.
Results are novel contributions to the literature. The previously observed association between serotonin functioning and alcohol use might be due, in part, to the fact that individuals with lower levels of serotonin functioning are predisposed towards developing earlier aggression/antisociality. Results did not support the hypothesis that serotonin functioning predisposes individuals to deficits in self-regulatory abilities. Findings extend previous research by suggesting that serotonin functioning and self-regulation might be transdiagnostic risk factors for many types of psychopathology.

Description
The nature and correlates of emerging internalizing symptoms in young children are largely unknown. Maternal factors such as psychological symptoms and detached parenting style have been found to be present in children with anxiety and depression. Further, child attentional control in task completion has been associated with difficulty related to internalizing problems. This study tested hypotheses that child anxiety and depression at age five could be predicted by a combination of maternal distress and maternal detached behavior recorded at age three. An additional hypothesis was tested to determine if child attentional control at age four may be a partial mediator of the relation between maternal symptoms and parenting to child internalizing symptoms. Using structural equation modeling, no hypotheses were supported; child internalizing problems were not significantly predicted by maternal distress nor detached parenting. Further, child attentional control was not predicted by maternal distress or detached behavior, nor did attentional control predict internalizing problems. Findings indicate that over a two-year interval, childhood internalizing problems at age five are likely best predicted by early internalizing problems at age three. There was no support that the mother or child factors tested were predictive of child outcomes.
