Brief 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.

Primary Outcome Measures
NameTimeMethod
Moderate to Vigorous Physical Activity (minutes / day); Youth Activity Profile (YAP) assessmentChange from baseline to 12 weeks

The estimate of daily MVPA is obtained from the calibrated , online self-report tool (Youth Activity Profile) built into the web-based content management system. Students complete 5 items capturing school activity and 5 items capturing home activity. The data are then processed using validated algorithms to create estimates of time spent in physical activity behavior.

Sedentary Behavior (hours / day); Youth Activity Profile (YAP) assessmentChange from baseline to 12 weeks

The estimate of time spent in sedentary behavior (outside of school) is obtained from a calibrated, online self-report tool (Youth Activity Profile) built into the web-based content management system. Students complete 5 items capturing general amounts of sedentary behavior. The data are then processed using validated algorithms to create estimates of time spent in sedentary behavior.

School Capacity for Wellness Programming; School Wellness Readiness AssessmentChange from baseline to 12 weeks

The assessment of school capacity for wellness programming is obtained at both pre and post time points using the School Wellness Readiness Assessment (SWRA) based on work by Holt et al. (2009). The instrument developed specifically for SWITCH captures Structural barriers (Individual and Organizational) and organizational barriers (Individual and Organizational). The instrument will be completed by the school core teams and the subscale scores will be averaged to create an overall indicator of School Capacity.

Secondary Outcome Measures
NameTimeMethod
Average Weekly Tracking Rate (%); Web-based SWITCH tracking toolChange from baseline to 12 weeks

Indicators of school, class and student implementation are obtained by computing engagement and utilization of the web-based SWITCH tracking system. Self-monitoring is a key mediating variable in the SWITCH program, so emphasis in training was placed on helping to promote utilization of the SWITCH tracking system to promote behavior change in the three target behaviors: PA ("do"), SB ("view"), and FV consumption ("chew").

Adherence to Quality Element (average score); Checkpoint Implementation SurveyChange from baseline to 12 weeks

The Checkpoint Implementation Surveys (CIS) were used in a formative way to guide to evaluate the degree to which schools followed the SWITCH 'quality elements' for overall school implementation. School teams self-reported the degree to which they followed each of the five quality elements using a 3-point scale (none = 1, somewhat = 2, and fully = 3). The average score was used as the overall indicator

Adherence to Best Practices (average score); Checkpoint Implementation SurveyChange from baseline to 12 weeks

The Checkpoint Implementation Surveys (CIS) were used in a formative way to guide to evaluate the degree to which schools followed the SWITCH 'best practices' in the three targeted settings (classrooms, physical education, and lunchroom). School teams self-reported the degree to which their school followed the 3 best practices in each setting using a 3-point scale (none = 1, somewhat = 2, and fully = 3). The average score is used as an overall indicator.
