“…Ajzen (1991Ajzen ( ,2013 and Han and Ryu (2012) asserted that a socio-psychological theory (e.g., TRA, TPB, MGB, Theory of Repurchase Decision-making [TRD]) in essence may be amended by modifying the linkages in the theory and incorporating additional variables that are critical in a particular setting if it can be shown that the theory, including new constructs, captures a greater proportion of the variance in one's intention or behavior after the original theory variables have been taken into account. Such amendment procedures, described as theory broadening and deepening (Perugini & Bagozzi, 2001), have been widely employed in various studies in a variety of contexts (e.g., Bagozzi & Dholakia, 2006;Carrus et al, 2008;Han & Ryu, 2012;Hunter, 2006;Song, Lee, Kang et al, 2012, Song, Lee, Norman et al, 2012Taylor, Ishida, & Wallace, 2009). These researchers generally showed that one of the MGB's theoretical mechanisms is better explained when revising paths to be more appropriate in a particular setting or when involving essential constructs that are important in specific contexts.…”
