The SNAP-Ed Toolkit is moving!

The Toolkit and its resources, including evidence-based interventions and the SNAP-Ed Evaluation Framework, will soon be housed within the SNAP-Ed Connection website. Please look for future communication regarding that transition. Thanks. — The Toolkit Team

School Physical Activity & Nutrition-Environment Tool (SPAN-ET)

Oregon State University Extension

Overview

The School Physical Activity and Nutrition Environment Tool (SPAN-ET) is a PSE Change tool used by school sector stakeholders to assess elementary and middle/high school resources and readiness to improve nutrition and physical activity (PA) environments, suggest appropriate improvement strategies, score and measure outcomes resulting from environmentally-based treatments. The elementary SPAN-ET includes 28 items-Area of Interest and middle/high HSPAN-ET includes 29 items-Areas of Interest in two main component categories, PA and nutrition, and considers the policy, situational, and physical environment within each component. 

Target Behavior: Healthy Eating, Physical Activity

Intervention Type: PSE Change

Intervention Reach and Adoption

SPAN-ET targets elementary school-aged youth (grades k-5/6) in SNAP-Ed eligible (>50% students eligible for free/reduced meals) elementary school settings. HSPAN-ET targets middle and high school-aged youth (grades 7-12) in SNAP-Ed eligible middle and high school settings.   

Setting: School

Age: Elementary School; Middle/High School

Race/Ethnicity: All

Intervention Components

SPAN-ET includes direct observation, interview, document review, and school wellness coalitions. Coalitions include SNAP-Ed staff, utilize the SPAN-ET Results and Resource Guide that provides assessment details to individual schools as to which criteria were met relative to their SPAN-ET scores, and links appropriate research-based, practice-based or emerging PSE strategies with each criterion to tailor school-based PSE implementation to unmet criteria. The HSPAN-ET engages middle and/or high school students as auditors to conduct direct observation, interview, and document review and participate as members of school wellness coalitions. These intervention components contribute to school environmental and policy improvements aimed at supporting students’ healthy weight, healthy dietary, and PA behaviors at school. 

Intervention Materials

Online materials (SPAN-ET) and self-directed online training modules are under development (pending funding).

Intervention Costs

SPAN-ET implementer training (4 modules), facilitated in person by Oregon State Extension master trainers using remote deliver (6 contact hours), costs $1650 to SPAN-ET adopting organization

 

Evidence Summary

The SPAN-ET was evaluated to be a reliable instrument for assessing the quality of elementary school PA and nutrition environments and a sensitive measure for objectively identifying specific attributes of SPAN-ET areas of interest (PSEs) to target for school environmental and policy improvements aimed at supporting students’ weight healthy dietary and PA behaviors at school.

Classification: Research-tested

Evaluation Indicators

Based on the SNAP-Ed Evaluation Framework, the following outcome indicators can be used to evaluate intervention progress and success.

Readiness and Capacity – Short Term (ST) Changes – Medium Term (MT) Effectiveness and Maintenance – Long Term (LT) Population Results (R)
Individual
Environmental Settings ST5ST7 MT5, MT6 LT5, LT6, LT9, LT10
Sectors of Influence

 

Evaluation Materials

The SPAN-ET is an environmental evaluation tool for assessing and prioritizing PSE interventions in schools; SPAN-ET population dose evaluation materials are now available (launched 2022). Developers proposed (pending funding) to validate the SPAN-ET item (Area of Interest) effectiveness relative to population-level dose (reach X strength). To date, examination has included only select SPAN-ET-driven PA PSE change relative to changes in reached students’ in-school PA bout behaviors and weekly levels.
