Table 3 Concurrent and Predictive Validity Tests for Original SEPA Scale

	SEPA at 6 months	SEPA at 12 months
7-day PAR at 6 months (minutes/week)	ρ = 0.464**	n/a
Accelerometer 6 months (minutes/week)	ρ = 0.273**	n/a
7-day PAR 6 months (meeting guidelines)	t(40) = −5.605**	n/a
Accelerometer 6 months (meeting guidelines)	t(18) = − 2.789*	n/a
7-day PAR at 12 months (minutes/week)^a	B = 0.368** SE = 0.109	ρ = 0.492**
Accelerometer 12 months (minutes/week)^a	B = 0.313** SE = 0.102	ρ = 0.340**
7-day PAR 12 months (meeting guidelines)	B = 0.129** SE = 0.472	t(64) = − 5.157**
Accelerometer 12 months (meeting guidelines)	B = 0.081 SE = 0.058	t(29) = − 2.565*

**p value < .01, *p value < .05, +p value < .1
Note a: In linear regression models, square root transformations were used for the outcome variables (7-day PAR and accelerometer-measured MVPA)
