Description
The tendency for psychopathology to aggregate within families is well-documented, though little is known regarding the level of specificity at which familial transmission of symptomology occurs. The current study first tested competing higher-order structures of psychopathology in adolescence, indexing general and more specific latent factors. Second, parent-offspring transmission was tested for broadband domain specificity versus transmission of a general liability for psychopathology. Lastly, genetic and environmental mechanisms underlying the familial aggregation of psychopathology were examined using nuclear twin-family models. The sample was comprised of five hundred adolescent twin pairs (mean age 13.24 years) and their parents drawn from the Wisconsin Twin Project. Twins and parents completed independent diagnostic interviews. For aim 1, correlated factors, bifactor, and general-factor models were tested using adolescent symptom count data. For aim 2, structural equation modeling was used to determine whether broadband domain-specific transmission effects were necessary to capture parent-offspring resemblance in psychopathology above and beyond a general transmission effect indexed by the latent correlation between a parental internalizing factor and offspring P-factor. For aim 3, general factor models were fitted in both generations, and factor scores were subsequently extracted and used in nuclear twin-family model testing. Results indicated that the bifactor model exhibited the best fit to the adolescent data. Familial aggregation of psychopathology was sufficiently accounted for by the transmission of a general liability. Lastly, the best fitting reduced nuclear twin-family model indicated that additive genetic, sibling-specific shared environmental, and nonshared environmental influences contributed to general psychopathology. Parent-offspring transmission was accounted for by shared genetics only, whereas co-twin aggregation was additionally explained by sibling-specific shared environmental factors. Results provide novel insight into the specificity and etiology of the familial aggregation of psychopathology.

Description
Development of effective therapeutic interventions for the treatment of mental health disorders has been a significant driving force in the search to understand the human brain. Current treatments for mental health disorders rely on modulating neurotransmitter systems such as norepinephrine (NE), serotonin (5-HT), dopamine (DA) and γ-aminobutyric acid (GABA) to achieve clinically relevant relief of symptoms. While many medications are available to the clinician that individually target these neural systems, treatment often results in patients reporting unwanted side effects or experiencing incomplete relief. To counter this lack of treatment efficacy, further investigation of other avenues for achieving similar or better outcomes and potentially reach patients refractory to common therapies must be undertaken. One of these potential new target systems is the endogenous cannabinoid system (ECS), which is currently composed of cannabinoid receptor 1 (CB1) and cannabinoid receptor 2 (CB2). These metabotropic seven transmembrane (7-TM) loop G-protein coupled receptors (GPCR) are responsible for mediating the effects of acute Cannabis ingestion as well as modulating several core functions of the nervous system including emotion, memory, and learning behavior. Due ubiquitous expression of ECS proteins, there is broad overlap between brain regions that show high levels of receptor expression and those thought to be involved in the etiology of a range of mental health disorders including depression, anxiety and schizophrenia. Consequently, modulation of cannabinoid receptor function is a novel and potentially clinically relevant mechanism for influencing the levels of other neuromodulators and neurotransmitters, such as dopamine, that are known to play crucial roles in the progression of mental illness. In addition, characterization of endogenous cannabinoids and cannabinoid receptors with respect to their normal physiological function and possible roles in pathophysiology may provide insight for the development of future ECS-based therapies.

Description
By focusing on photojournalists for LIFE and Ladies’ Home Journal, I investigate mental health care in state institutions located in America during the Great Depression and World War II immediately prior to the great deinstitutionalization that began in the 1950s. Relying upon scholars of medical humanities, social theory, disability studies, feminist studies, the history of psychiatry, and the history of art, I consider the iconography used to represent mental illness in photography during the first half of the twentieth century to explore the ways mentally ill individuals were presented as disordered and lacking humanity. I explore the didactic nature of both photography and film, emphasizing how the artists and directors imbued their mediums with medical credibility and authority. The photographs of Alfred Eisenstaedt, Jerry Cooke, and Esther Bubley from the 1930-40s reveal the state of mental health care in America during the Great Depression and World War II. I will investigate the stereotypes seen in representations of mental illness in photographs and how these depictions shaped and were in dialogue with popular films like Spellbound (1945), The Snake Pit (1948), The Three Faces of Eve (1957), and Marnie (1964). As a point of contrast to the images and films representing mental illness, I examine depictions of healthy people in mental health clinics during this time. Finally, I offer four examples of public, contemporary art, including House for a Gordian Knot (2013), Bloom (2013), 1000 Shadows (2013), and Faces of Mental Health Recovery (2013), that explore mental illness to illustrate the enduring legacy of the iconography and stereotypes represented in the photography and films explored in the first half of this dissertation.

Description
Youth who turn 18 in the foster care system often face the difficulty of transitioning to adulthood without traditional emotional and financial supports. Early experiences of trauma impact their mental health and receipt of services both while in care as well as decisions whether to continue services after leaving care.
Using the behavior analytic model, this dissertation explores the challenging and supportive situations former foster youth experience with mental health services while transitioning to adulthood. Qualitative interviews and focus groups inform the development of a quantitative instrument in a mixed methods, sequential exploratory research design. The resulting instrument identifies the most intense and frequently encountered situations former foster youth experience, related to their mental health and transitions to adulthood.
Results indicate the most challenging situations foster youth experience during the transition are related to overwhelming expectations, receiving mixed messages from professionals, feelings of isolation, and a lack of voice and choice with regard to mental health services. Young adults in this study also emphasized the importance of responsive engagement, self-efficacy, and consistency in relationships both formally and informally.
This research provides important implications for social work practice, policy, and education. Acknowledging the voice of foster youth gives them a choice in services and allows for realistic transition planning. Developing problem-solving skills and a support network beyond foster care are necessary strategies of preparation to age out. Finally, practitioners should recognize the impact of trauma and other contextual factors when conducting assessment and treatment, to promote positive outcomes.

Description
The purpose of this study is to understand and explore the perspectives of caregivers of children receiving mental health services in the Southwest. The data collected examines areas of caregiver satisfaction of services including, perceived barriers and agency’s ability to effectively apply the System of Care model’s core values. Participants (N=100) were interviewed using the System of Care Practice Review, Revised. Data results include descriptive quantitative analysis, correlation and means comparisons, and thematic analysis of qualitative responses. The research indicates that as a whole, caregivers are satisfied with child mental health services. Data suggests that providers should continue to strive for improvement and excellence in several areas of service, including intervention effectiveness, family participation, cultural competence, communication and interpersonal relationships.

Description
Procedural justice has become a widely researched topic in the criminological field with applicability to multiple arenas, including policing, corrections, and courts. Its main tenents suggest that through fair treatment, respectful dialogue and being given a proper voice, citizens will view their experiences with authority more justly. However, though the literature regarding procedural justice has grown immensely, it is still unclear whether certain characteristics of individuals, such as gender and mental health, play a role in their perceptions of procedural justice. Using secondary data originally collected for Rossman, Roman, Zweig, Rempel and Lindquist’s Multi-Adult Drug Court Evaluation (MADCE), an attempt is made to address the previously neglected association between procedural justice, gender, mental health and the added aspect of specialized drug court participation. Results suggest that both gender and mental health, namely depression, play a significant role in predicting procedural justice. Additionally, being a drug court participant was significantly related to higher levels of perceived procedural justice. Implications for theory, research, and policy are discussed.

Description
Romantic relationships are an important aspect of anyone's life. For individuals with an autism spectrum disorder, this is true as well. However, these people may experience relational dynamics and trajectories that are in some aspects either similar to or markedly different from those who are not on the spectrum. There are very few studies analyzing and understanding how adults with an ASD navigate romantic relationships. This particular study examined how turning points pertaining to relational escalation or de-escalation were recognized and understood by eight individuals (four men and four women) possessing an ASD. The Retrospective Interview Technique (RIT) was implemented in order to accrue data from participants. Each participant completed a RIT graph mapping out a romantic relationship of their choice by understanding when a turning point was identified and placing a mark next to the corresponding level of relational closeness or attachment. Once all turning points were mapped out, they were connected with lines so that a visual representation of the entire relationship may be viewed. Participants were then queried about how they knew that particular event (or mark) to be a turning point, how it impacted the relationship, and how they were, personally, influenced by it (how they responded to the event). Interviews were transcribed and explored through a grounded theory approach. Specifically, Braun and Clarke's thematic analysis method was applied to articulate interview data. The research revealed four main themes (Relational Genesis, Relational Escalation, Relational De-escalation and Conflict Management) as well as seventeen sub themes. Limitations for this study, information relating to discourses surrounding autism spectrum disorders and romantically intimate relationships, as well as, areas for future study are also discussed.

Description
The relationship between stress and policing has long been established in literature. What is less clear, however, is what departments are doing to help officers deal with the stress that comes with the job. Looking at a small Southwestern police agency and using a modified version of Speilberger’s (1981) Police Stress Survey, the present study sought to examine stressors inherent to policing, as well as to identify departmental services that may be in place to help officers alleviate those stressors and whether or not police officers would choose to take part in the services that may be offered. The findings suggest that a shift in stress in policing is occurring with operational stressors being reported at higher levels than organizational stressors, contrary to previous research.

Description
The purpose of this study was to examine the contributions of language anxiety, acculturation and social connectedness with American people to the counseling self-efficacy of international counseling students (ICSs) in the United States. The study used hierarchical multiple regression analysis with a sample of ICSs from counseling, counseling psychology and related programs in the U.S. (N=72). Major findings indicated that ICSs’ language anxiety was inversely associated with their counseling self-efficacy; neither ICSs’ acculturation nor social connectedness with American people had a significant relationship with counseling self-efficacy. Further, there was no significant interaction between language anxiety and social connectedness with American people; language anxiety, acculturation, social connectedness with American people, and the interaction between language anxiety and social connectedness with American people together did not account for a significantly different amount of variance in counseling self-efficacy over and above the variance accounted for by language anxiety alone. Implications, limitations and recommendations for future research are discussed.

Description
Many medical students are reluctant to seek help during the course of their four years of medical school. When they do finally ask for help, some are already burned out or in a crisis. One of the main reasons students are apprehensive about seeking help is stigma. This mixed methods action research study was conducted to explore whether a help-seeking, anti-stigma campaign improved help-seeking behaviors. The innovation was an anti-stigma campaign consisting of three components: (a) video vignettes of upper class students normalizing help-seeking, (b) a Friends and Family of Medical Students session to educate those closest to the student about medical school, and (c) an anonymous, online mental health screening tool. Data from the General Help-Seeking Questionnaire, individual interviews, and institutional data from the medical school provided information about the effects of the campaign and determined factors influencing help-seeking. Using these strategies, I hoped to normalize help-seeking and break down the barriers of stigma. Major findings included: Students were more likely to seek help from personal resources (close family and friends); Students may be more proactive with personal resources, but need prompting for college or formal resources; Students’ beliefs and attitudes were influenced by those closest to them and; First year students were more likely to seek help than their second year classmates. In addition, data inspired future research ideas and programming regarding the topic of help-seeking in medical school.
