“…Furthermore, many constructs in research cannot be expected to be independent of each other, so the oblique rotation approach would be appropriate to obtain several theoretically meaningful factors (Hair et al, 1998). Promax is one of the most commonly used oblique rotation methods (DeCoster, 1998;Biber, 2009) which has been adopted by a number of researchers (Pham and Swierczek, 2006;Lam et al, 2008;Chan and Lee, 2009;Kärnä et al, 2009). Therefore, Promax rotation method was finally applied to this study for further discussion.…”
