“…Therefore, its factorial structure evidence is based on two sources: the confirmation of the factorial structure of the work-life balance concept of the SWING-SSC applying confirmatory factor analysis (CFA) and, based on results of recent studies (Greenhaus & Allen, 2011) on the test of the criterion validity using theoretically important external variables (health, role conflict, role clarity and supervisor support). We expect strong associations between negative WHI/ negative HWI with decreased levels of health (Hanson et al, 2006;van Steenbergen & Ellemers, 2009), positive relation between supervisor support and positive WHI (McCarthy, Darcy, & Grady, 2010;Taylor, Del Campo, & Blancero, 2009). We expect positive relation between role conflict and negative WHI (Bacharach, Bamberger, & Conley, 1991;Greenhaus & Beutell, 1985;Katz & Kahn, 1978;Rau & Hyland, 2002), and positive relation between role clarity and positive WHI (Kahn, Wolfe, Quinn, Snoek & Rosenthal, 1964;Lang, Thomas, Bliese, & Adler, 2007;Matsui, Ohsawa, & Onglatco, 1995;Rothbard, 2001;Rothbard & Dumas, 2006;Rothbard & Edwards, 2003).…”
