Background: Healthcare providers are encouraged to prepare their practice to effectively manage the care of mild to moderate adolescent depression. Cost-effective screening, diagnostic, and newly developed pediatric primary care depression management guidelines have been established. To integrate guidelines into practice, primary care providers (PCPs) must document effectively to ensure a complete treatment plan is in place in the patient’s electronic health record (EHR).

Intervention: Elements from a flowsheet were implemented into the EHR to promote thorough assessment and documentation of care delivered to adolescents with depression.

Methods: An initial chart review was completed on patients diagnosed with depression. An updated depression template was implemented within the EHR for six weeks. A follow-up chart review was completed post-intervention to determine if documentation of elements from the adolescent depression guidelines improved after the EHR update. Pre-intervention and post- intervention surveys were delivered to PCP’s to understand their perspective on adolescent depression management.

Outcomes: The chart review revealed that baseline PHQ-9 screenings were documented in 91% (n=43) of the charts reviewed in the pre-intervention timeframe. Only 78% (n=7) of the charts reviewed during post-intervention included PHQ-9 screenings. Early intervention treatment options documented in the pre-intervention timeframe included education 100% (n=47), medication prescriptions 53% (n=25), and psychotherapy referrals 18% (n=18). During post- intervention, education 100% (n=9), medication prescriptions 78% (7), and psychotherapy referrals 22% (n=7) were documented by the PCPs.

Recommendation: The quality improvement project focused heavily on documentation completed over a one year pre-intervention timeframe compared to a six-week post-intervention timeframe. Further evaluation and chart review over the next year will provide a more adequate comparison of documentation within primary care practice.

There is an increase in the prevalence of mental health problems in the United States. Healthy People 2020’s leading mental health indicator is to increase the delivery of care to those with mental health issues and lower the number of youth who experience a major depressive disorder. Teachers and non-teaching staff are well placed in the community to identify youth undergoing emotional distress and facilitate early interventions, yet do not receive adequate training in mental health.

A project was undertaken to determine if a mental health training intervention affected the community youth mentors knowledge, attitude and self-efficacy towards helping youth with mental health issues. Three instruments with good validity and reliability namely Mental Health Literacy Scale (MHLS), Attitudes to Severe Mental Illness (ASMI) scale, and Gatekeeper Behavior Scale were used in pre intervention, immediately post intervention and two weeks post intervention questionnaires. The Wilcoxon Signed Ranks test indicated changes in the pre and post intervention scores as significant in knowledge, and attitude between pre intervention and immediately post intervention time periods. Cohen’s effect size value suggested large, medium, small, and minimum clinical significance in the variables over period of time.

Mental health literacy narrows the gap between symptom onset and intervention. Numerous mental health trainings are currently available worldwide. Schools and after school clubs in collaboration with hospital mental health and other community agencies are better equipped to bridge the gap. School staff report better confidence in addressing mental health and behavioral health issues among youth when equipped with additional resources within the school in the form of psychologists, social workers, and counselors.

Phoenix is the sixth most populated city in the United States and the 12th largest metropolitan area by population, with about 4.4 million people. As the region continues to grow, the demand for housing and jobs within the metropolitan area is projected to rise under uncertain climate conditions.

Undergraduate and graduate students from Engineering, Sustainability, and Urban Planning in ASU’s Urban Infrastructure Anatomy and Sustainable Development course evaluated the water, energy, and infrastructure changes that result from smart growth in Phoenix, Arizona. The Maricopa Association of Government's Sustainable Transportation and Land Use Integration Study identified a market for 485,000 residential dwelling units in the urban core. Household water and energy use changes, changes in infrastructure needs, and financial and economic savings are assessed along with associated energy use and greenhouse gas emissions.

The course project has produced data on sustainable development in Phoenix and the findings will be made available through ASU’s Urban Sustainability Lab.

Hybrid system models - those devised from two or more disparate sub-system models - provide a number of benefits in terms of conceptualization, development, and assessment of dynamical systems. The decomposition approach helps to formulate complex interactions that are otherwise difficult or impractical to express. However, hybrid model development and usage can introduce complexity that emerges from the composition itself.

To improve assurance of model correctness, sub-systems using disparate modeling formalisms must be integrated above and beyond just the data and control level; their composition must have model specification and simulation execution aspects as well. Poly-formalism composition is one approach to composing models in this manner.

This dissertation describes a poly-formalism composition between a Discrete EVent System specification (DEVS) model and a Cellular Automata (CA) model types. These model specifications have been chosen for their broad applicability in important and emerging domains. An agent-environment domain exemplifies the composition approach. The inherent spatial relations within a CA make it well-suited for environmental representations. Similarly, the component-based nature of agents fits well within the hierarchical component structure of DEVS.

This composition employs the use of a third model, called an interaction model, that includes methods for integrating the two model types at a formalism level, at a systems architecture level, and at a model execution level. A prototype framework using DEVS for the agent model and GRASS for the environment has been developed and is described. Furthermore, this dissertation explains how the concepts of this composition approach are being applied to a real-world research project.

This dissertation expands the tool set modelers in computer science and other disciplines have in order to build hybrid system models, and provides an interaction model for an on-going research project. The concepts and models presented in this dissertation demonstrate the feasibility of composition between discrete-event agents and discrete-time cellular automata. Furthermore, it provides concepts and models that may be applied directly, or used by a modeler to devise compositions for other research efforts.
