Summary of Process Evaluation Methods

Characteristic of Change Model Addressed	Year	Data Sources	Timing for Implementation Assessment	Procedures
Completeness: children have opportunity to obtain MVPA Move Inside: ≥ 10 min/day Move Outside: ≥ two 20-min sessions of recess & 5 min of structured PA daily Move to Learn: ≥ two 5-min activities daily	1	Observe intervention implementation	Fall: 4 days Spring: 4 days	Process evaluator used checklist to observe throughout school day; daily mean calculated
		Teachers	Once per year in Spring	Self-completed survey; % weekly goal met calculated
	2 & 3	Observe intervention implementation	Fall: 1 day Spring: 1 day	Process evaluator used checklist to observe throughout school day; daily mean calculated
		Teachers	Once per year in Spring	Self-completed survey; % weekly goal met calculated
Fidelity-PA: children were physically active during opportunity Characteristics of PA Opportunities: ≥ 50% of opportunity time in MVPA	2 & 3	Observe classroom level PA at 5-min intervals	Fall: 1 day Spring: 1 day	Process evaluator used OSRAC-P to observe child PA during intervention components; mean daily % time in PA calculated
Total PA for whole school day: % time spent in Total PA during school day	1	Observe classroom level PA at 5-min intervals	Fall: 4 days Spring: 4 days	Process evaluator used OSRAC-P to observe a subset of children throughout school day; % time in activity calculated
	2 & 3		Fall: 1 day Spring: 1 day
Fidelity-Social environment: modeling & prompting for PA and enjoyment Social Environment: -Teachers and adult staff verbally encourage PA in children during all PA time -Teachers and adult staff actively participate in PA with children during all PA time	1	Observe intervention implementation	Fall: 4 days Spring: 4 days	Process evaluator used checklist to observe throughout school day; daily mean calculated
	2 & 3		Fall: 1 day Spring: 1 day
	2 & 3	Teachers		Self-completed survey; mean % weekly goal met calculated
	2 & 3	Interventionists		Interventionists used rating scale; mean calculated
Enjoyment: Children enjoy PA	2 & 3	Observe intervention implementation	Fall: 1 day Spring: 1 day	Process evaluator used checklist to observe throughout school day; daily mean calculated
	2 & 3	Teachers	Once per year in Spring	Self-completed survey; % weekly goal met calculated
Overall Implementation	1–3	Interventionists	Once per year in Spring	Interventionists used rating scale; mean calculated

Move Inside: adult-led, structured physical activity; Move Outside: recess; Move to Learn: daily lessons; Total PA: light + moderate + vigorous physical activity.

Abbreviations: PA, physical activity; MVPA, moderate to vigorous physical activity.
