Eigen value	3.4	1.5	1.3
Cronbach's alpha (α)	0.7	0.7	0.5
Percent variance explained (%)	28.5	12.1	11.0
Weighted factor based scale score^a (median & IQR)	16.7 (15.1, 17.8)	10.5 (9.2, 13.0)	4.4 (3.6, 5.2)
Unweighted factor based scale score^b (median & IQR)	26.0 (24.0, 28.0)	15.0 (13.0, 19.0)	6.0 (5.0, 7.0)

Note: Principal Component extraction method with oblim rotation (Kaiser Normalisation); ^a = weighted factor based scale score using the method described by de Vaus; ^b = Unweighted factor based scale score mean; and ^⌂ = Item has been reversely coded so that a higher score is positively linked with physical activity participation.
