“…Moreover, several IS dominant theories (e.g., Davis' 1989 Technology Acceptance Model (TAM) and Doll and Torkzadeh's 1991 user participation/involvement model; quoted in Chin et al, 2003, p. 192) as well as the streams of research that have extended these models (e.g., Barki et al, 2007;Bhattacherjee & Sanford, 2006;Brown et al, 2010;Carswell & Venkatesh, 2002;Chin et al, 2008;Davis & Venkatesh, 2004;Devaraj et al, 2008;Hartwick & Barki, 1994;Karahanna et al, 2006;Limayem et al, 2007;Morris & Venkatesh, 2010;Venkatesh & Davis, 2000;Venkatesh & Speier, 1999;Venkatesh & Speier, 2000;Venkatesh & Johnson, 2002;Venkatesh et al, 2003;Venkatesh et al, 2008) suggest that moderator variables are an important avenue of future development. Furthermore, numerous researchers within the IS field have suggested that models using moderator variables be tested (Anderson, 1985, Doll & Torkzadeh, 1989, Ives & Olson, 1984, McKeen et al, 1994, Sambamurthy & Zmud, 1999, Tait & Vessey, 1988; quoted in Chin et al, 2003, p. 192;Barki et al, 2007;Brown et al, 2010) as have researchers in other fields (Chin et al, 2003).…”
