“…The studies that tested JCQ reliability and validity (mostly, decision latitude, psychological job demands, supervisor support, and co-worker support scales) have generally found acceptable psychometric characteristics and substantial comparability of the JCQ scales across populations (Choi et al, 2009;Fransson et al, 2012;Jabali et al, 2013), despite some exceptions, as is the case of the psychological job demands scale, that shows low internal consistency in some studies (Kawakami et al, 1995;Phakthongsuk, & Apakupakul, 2008). The studies also found different results in the decision latitude scale that can challenge the theoretical framework: some identify two factors in that scale -skill discretion and decision authority (Chien et al, 2011;Karasek et al, 1998;Smith, Tisak, Hahn, & Schmieder, 1997) -, and others only one factor (Niedhammer et al, 2006;Pelfrene et al, 2001;Phakthongsuk, & Apakupakul, 2008;Zotnierczyk-Zreda, & Bedyriska, 2014).…”
