“…Some studies, however, have found different factor solutions. A few studies supported the original unidimensional structure of the scale (Crockett, Weinman, Hankins, & Marteau, 2009;Hevey, Pertl, Thomas, Maher, Craig, & Ni Chuinneagain, 2010), whereas other studies supported a bifactor model (McKay, Cole, & Percy, 2015;McKay, Morgan, van Exel, & Worrell, 2015) or found factor structures with more than two factors (Ainin, Jaafar, & Dezdar, 2015;Ryack, 2012;Zhang, Kong, Zhang, & Li, 2015). The majority of the evidence seems to suggest that a two-factor model fits the CFC scale best.…”
