RA relative advantage, CB compatibility, SC security concern, TR management support, TL top management support, FS firm size, ES external support, EP external pressure, RE regulatory environment, AD adoption situation.
^aS.D. denotes the standard deviation.
^bConstruct reliability = (sum of standardized loadings)²/ [(sum of standardized loadings)² + (sum of indicator measurement error)]; the indicator measurement error is calculated as 1- (standardized loading)².
^cSquare root of the average variance extracted (AVE) (in bold on diagonal).
^dCorrelation is significant at the 0.05 level.
