Table 4 PASE construct validity results

	Men (n = 25)		Women (n = 25)
	r	p-value	r	p-value
	Mean (95% CI)		Mean (95% CI)
PASE total score vs.:
aPAL (counts∙min^-1)	0.45 (0.09 to 0.71)	0.01	0.06 (-0.24 to 0.36)	0.39
PASE sub-scores vs. activity intensity:
low (min∙day^-1)	0.22 (-0.13 to 0.53)	0.15	-0.01 (-0.30 to 0.30)	0.48
moderate-to-high (min∙day^-1)	-0.14 (-0.41 to 0.30)	0.25	0.09 (-0.29 to 0.48)	0.33
