The project is designed to evaluate a participatory implementation model in HealthCorps (HC) high schools and to assess outcomes within and across school settings . The behavioral objectives from the 2010 Dietary Guidelines to address obesity in youth include: 1) decreasing sugary beverage intake; 2) increasing frequency of breakfast; 3) increasing vegetable and fruit intake to 2½ cups per day;4) decreasing frequency of fast food meals;5) becoming physically active (goal of 1 hour per day); and 6) reducing sedentary behavior time (<2 hour day). The study is employing system dynamics modeling (SDM) to assess wellness programming options and to evaluate the program implementation within the context of diverse school ecologies. The RE-AIM evaluation metric (Reach, Effectiveness, Adoption, Implementation, and Maintenance) is used to guide SDM development and validation.

The Specific Aims are:

1. To use PAR (Participatory Action Research) methods to refine the school wellness program model and toolkit components that address institutional/community level program implementation barriers and individual level barriers to achieving healthy lifestyle recommendations.
2. To assess the effectiveness of program components using process evaluation techniques guided by the RE-AIM (Reach, Effectiveness, Adoption, Implementation, and Maintenance) model.
3. To evaluate implementation with system dynamics modeling to facilitate dissemination. The simulation analysis will apply the RE-AIM framework to address: Reach (participation rates), effectiveness (outcomes), adoption (acceptability), implementation (intervention fidelity), and maintenance (sustainability of lifestyle changes by students and programs by schools), in order to facilitate refining the toolkits and training program for dissemination to other school setting and diverse educational venues.

This research project focuses on enhancing implementation of school wellness activities with the goal of achieving federal lifestyle recommendations to reduce obesity. The study will evaluate whether using a toolkit approach with problem-solving and other strategies helps schools and students develop healthier lifestyle choices.

At the school level, we will focus on implementation barriers identified by (or brought to) the school Wellness Champion Network (e.g., crowded gym, lack of equipment, food service issues) using a toolkit approach that builds on the Alliance for a Healthier Generation school toolkits.

At the student level, the toolkit will focus on a self-assessed health-behavior feedback mechanism to personalize behavioral goal setting when addressing obesity related lifestyle recommendations.

An iterative intervention dissemination will be used to achieve sequential roll out to all HealthCorps-affiliated Living Lab schools over time. This design allows for an increasingly larger selection of schools to receive the enhanced support through participation research principles to determine how to address obesity-related school mandates. Consistent with participatory research principles, all HealthCorps coordinators have received training to function as Wellness Council facilitators. This study will evaluate a participatory implementation model designed to extend wellness and stakeholder collaborations towards achieving policy standards and goals focusing on the school wellness network. By the end of the study, all HealthCorps Living Labs schools will be implementing this participatory implementation for wellness programming.

This implementation approach increases the potential for learning lessons that can be generalized more widely as in pragmatic trials. In keeping with participatory research principles, school Wellness Councils will use data obtained during the trial as feedback for potential refinement of their toolkit components.

The research team will work with school Wellness Councils and key stakeholders to develop additional school toolkit items utilizing problem-solving strategies and low-cost methods to address implementation barriers. The elements of participatory action research focus on forming a school Wellness Council partnership to build trust, shared vision, and mutual capacity, and includes engagement at multiple levels as well as active participation of stakeholders to create more salient and effective programs. The HealthCorps coordinator will guide stakeholders via the Wellness Council network and by specific program area to engage in a 6-step iterative process listed below:

1. Examine local indicator data e.g., FitnessGram, Health Behavior Survey with Youth Behavioral Risk Factor Surveillance System (YBRFSS) items, food service data, school environment/climate data, community data
2. Consider how current programs/curricula and alternatives relate to behavioral indicators (using a social ecological framework) to student, family, school, and community consideration of media and other spheres of influence,
3. Develop program/curriculum S.M.A.R.T. (specific, measurable, attainable, realistic and time limited (considering semester/school year)) goals focusing on Dietary Guidelines, mental resilience, and FitnessGram indicators
4. Identify barriers and develop strategies for the school and student toolkit
5. Implement school program elements with ongoing monitoring by stakeholders and the Wellness Council
6. Use an iterative process to adapt to new needs and sustain program

Basic simulation models will be used to demonstrate the potential effects of implementing a given toolkit option. The school and student toolkits developed during the formative evaluation will serve as a template to be used with the intervention schools. The initial training and guide/toolkit formatting will be based on those used by the Alliance for a Healthier Generation in their school wellness programming. Initial feedback from HealthCorps coordinators indicates that the Alliance Wellness Council guide/toolkit can be readily implemented in HealthCorps high schools. The HealthCorps coordinators will build on the Alliance's collaborative guidelines and training to enhance collaboration as an active Wellness Council. In addition, to build youth leadership thereby obtaining student support, the toolkit will include demonstration exercises to be lead by HealthCorps coordinators in collaboration with student leaders and school wellness stakeholders. These demonstration activities, linked to the intervention's behavioral objectives, provide share-able knowledge and skills to promote positive health behavior change.

The outcomes simulation will expand the types of data used to include the survey's psychosocial variables and extensive administrative data such as attendance, demographics, and reduced/free lunch and student, teacher and parent school evaluations.
