NP18 (continued) Evaluation: CK, NE, and CD were poorly attended, and ID showed little change for the amount of time/cost, sug- gesting these four components lacked feasibility. Given small cell sizes, we utilized descriptive analyses of pre- post changes in mean scores and present Cohen’s d effect sizes comparing the MD/CW to the control condition. The MD/CW combination showed pre-post increased fruit/ vegetable intake (0.16), decreased sugar sweetened beverages (-0.22), decreased fast food consumption (-0.36), de- creased parental low preferences for cooking (-0.20), increased use of more whole foods in meal preparation (0.24), decreased food insecurity (0.22), increased basic cook- ware sufficiency (0.42), and increased family functioning (0.36). However, the effect size for changes in parents/ children eating together was negligible (0.05). We are partnering with Meals on Wheels as the preparation/ delivery modality in evaluating MD/CW in an RCT. Conclusions and Implications: Results will inform policy (e.g. where limited resources may be best allo- cated) and interventions (e.g. supports most effective in promoting family meals).

NP19 Farm Fresh Foods for Healthy Kids: Innovative Cost-Offset Community Supported Agriculture Intervention Rebecca Seguin, PhD, rs946@cornell.edu, Cornell University, 412 Savage Hall, Ithaca, NY 14853; Alice Ammerman, DPH, University of North Carolina, Chapel Hill; Karla Hanson, PhD, Cornell University; Jane Kolodinsky, PhD, University of Vermont; Stephanie Jilcott Pitts, PhD, East Carolina University; Marilyn Sitaker, MPH, The Evergreen State College Objective: To better understand potential supports and barriers to cost-offset community supported agriculture (CO- CSA) for low-income families. Description: Formative interviews were conducted with adults (n = 41) and children (n = 20) from low-income households and cooperative extension nutrition educa- tors (n = 20). Adults from low-income households also completed a choice experiment to examine willingness to participate in CSA under a variety of price, distance, and content conditions. Evaluation: Formative interviews revealed parents were unfamiliar with CSA, and most were worried about cost, accessibility, produce quality, and selection. Their optimal CSA share would have 8 to 9 items of mixed variety, pick- up every other week, price less than $15, no more than 10 minutes further than the supermarket, and preferably less expensive but no more than 20% more expensive than supermarket prices. Formative interviews with educators revealed positive views toward local foods and the impor- tance of integrating local foods into extension programming. Conclusions and Implications: Findings from the for- mative research informed the Farm Fresh Foods for Healthy Kids (F3HK) intervention which included a 15–24 week summer CO-CSA share (50% subsidy), weekly payments (allowing SNAP-EBT), 2–4 cooking tools, and 9 CSA- tailored education classes. Fourteen focus groups were conducted with F3HK participants following the first year of CSA participation to understand challenges faced and support received. Unfamiliar foods, storage, and spoilage were challenges with CO-CSA; the CSA-tailored classes and farmer advice and newsletters helped in this regard. F3HK participants generally thought the CO-CSA was afford- able; they reported that farmers were helpful working out alternate payment arrangements when needed. The F3HK intervention trial incorporates modest adaptions to the tra- ditional CSA model in order to make participation feasible for low-income families. Despite these adaptations, addi- tional support may be needed to promote full participation and enhance produce use. Funding: 2015-68001-23230. NP20 Feasibility of the SWITCH™ Implementation Framework for Enhancing School Wellness Gregory J. Welk, PhD, gwelk@iastate.edu, Iowa State University, 534 Wallace Avenue, Ames, IA 50010; Lorraine Lanningham-Foster, PhD; Spyridoula Vazou, PhD; Doug Gentile, PhD; Senlin Chen, PhD, Louisiana State University; David A. Dzewaltowski, PhD, University of Nebraska Medical Center; Richard R. Rosenkranz, PhD, Kansas State University; Joey Lee, MS, Iowa State University; Maren M. Wolff, MS; Kyle J. Braun, BS, Kansas State University Objective: There is a need to identify strategies that enhance the implementation of evidence-based school well- ness interventions in real-world settings. The present study evaluates the feasibility of empowering school wellness leaders to deliver an evidence-based, childhood obesity- prevention initiative called SWITCH™ (School Wellness Integration Targeting Child Health). We specifically evalu- ated the utility of a new implementation process, based on the robust Healthy Youth Places (HYP) framework, to increase capacity of school leaders to lead SWITCH™ school wellness programming. Description: The implementation process was piloted in a convenience sample of eight Iowa elementary schools. Teams of three leaders from each school attended an in- person school wellness conference, followed by five online webinar sessions delivered by two trained facilitators. The capacity building and quality improvement process was designed to empower schools to lead school wellness change using methods and concepts from the original 12-week SWITCH™ program. School coordinators completed check- lists on two occasions to assess overall school-level implementation as well as setting-level changes in phys- ical education, classrooms, and lunchroom. Student acceptability of SWITCH™ was evaluated by the degree of behavior tracking within the online SWITCH™ “Tracker” system that promoted self-monitoring.
