  1. 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.
