Summary

The SWITCH (School Wellness Integration Targeting Child Health) project is a multi-component intervention designed to support school wellness programming and contribute to youth obesity prevention. Consistent with social-ecological models, SWITCH is designed to reach multiple settings within schools while also facilitating engagement with families and community partners. The program focuses on three distinct behaviors known to impact obesity (i.e., physical activity (PA), sedentary behavior (SB) and fruit and vegetable consumption (FV)) in a creative way by challenging children to "switch what they do, view and chew".

Detailed description

Schools provide an ideal setting for coordinated youth obesity prevention but it has proven difficult to widely disseminate evidence-based programs in a cost-effective way. Multi-component programs that target multiple behaviors and reach multiple settings have been widely recommended in both scientific literature and in public health guidelines documents, but there are few examples of integrated social-ecological approaches that offer promise for broad dissemination. SWITCH initially began as a controlled childhood obesity intervention trial. A limitation of the original SWITCH program is that the print-based materials made it cost-prohibitive to promote broader dissemination, or to engage other schools. Therefore, the focus of subsequent work focused on developing and testing implementation strategies that would enable SWITCH to be more widely disseminated. In a controlled effectiveness study, we demonstrated that a web-based version had similar utility and outcomes as the print-based program, but effects were directly related to the degree of engagement within the school. Through a USDA-funded project, we developed a novel training method designed to facilitate greater adoption and more effective implementation of SWITCH in schools. The focus in this revised SWITCH model was on helping schools to independently manage the implementation of the evidence-based SWITCH program as part of overall school wellness programming. Thus, we have gradually evolved SWITCH from a school-based intervention conducted through schools to a school wellness training method provided for schools. Schools received Before moving to broader dissemination efforts it was important to determine the dose of training and support needed to assist schools with implementation. Therefore, the focus of this study was on comparing two different implementation approaches. An enhanced capacity building model that included personalized webinars with school leaders (Enhanced) was compared to a streamlined model based on email communication (Standard). Thus, a key goal is to determine the additive benefit of the enhanced school support relative to the standard implementation. Past work has demonstrated that there is considerable variability in the capacity of schools to take on and lead school wellness programming. Therefore, the analyses also directly examined the moderating influence of school capacity on implementation as well as the impact of implementation on outcomes.

Interventions

Type	Name	Description
BEHAVIORAL	Standard Implementation	Schools in the Standard implementation model received web-based training, access to on online education / tracking system and programming resources (modules, posters, trinkets) to facilitate wellness programming in their school. They completed audit tools at the beginning to facilitate goal setting and received weekly emails during the 12-week implementation process.
BEHAVIORAL	Enhanced Implementation	Schools in the Enhanced implementation model received the same training, web-access, and programming resources as those in the Standard implementation, but also received enhanced monthly support during implementation from the project team. The supplemental web calls (completed jointly by Extension leaders and SWITCH staff) utilized motivational interviewing to help schools build capacity and to enhance motivation for wellness programming.
