The model compares non-users and users. For non-users, Perceived Support, P S, predicts Perceived Ease of Use, P E U, with 0.75 and three asterisks. Perceived Ease of Use predicts Perceived Usefulness, P U, with 0.93 and three asterisks. Perceived Usefulness predicts Adoption Intention, A I, with 0.63 and one asterisk. Attitude of Adoption, A A, predicts Adoption Intention with 0.71 and three asterisks. Environment, E N V, predicts Perceived Ease of Use with 0.12 and one asterisk, and Adoption Intention with 0.29 and three asterisks. The correlation between P U 1 and P U 2 is 0.21. Indicator loadings are 0.63, 0.89 and 0.83 for P S 1 to P S 3; 0.70, 0.75 and 0.80 for P E U 1 to P E U 3; 0.74, 0.82, 0.87 and 0.84 for P U 1 to P U 4; 0.78, 0.89 and 0.83 for A A 1 to A A 3; 0.81, 0.87 and 0.76 for A I 1 to A I 3; and 0.91, 0.93 and 0.83 for E N V 1 to E N V 3. For users, Support Quality, S Q, predicts Perceived Ease of Use with 0.35 and three asterisks. Perceived Ease of Use predicts Perceived Usefulness with 0.84 and three asterisks, Attitude of Adoption with 0.81 and three asterisks, and Adoption Decision, A D, with 0.46 and three asterisks. Perceived Usefulness predicts Adoption Decision with 0.25 and two asterisks. Attitude of Adoption predicts Adoption Decision with 0.34 and three asterisks. Environment predicts Perceived Ease of Use with 0.55 and three asterisks. The correlation between P U 1 and P U 2 is 0.45. Indicator loadings are 0.88, 0.88 and 0.68 for S Q 1 to S Q 3; 0.84, 0.84 and 0.85 for P E U 1 to P E U 3; 0.68, 0.76, 0.93 and 0.89 for P U 1 to P U 4; 0.93, 0.96 and 0.94 for A A 1 to A A 3; 0.89, 0.90 and 0.85 for A I 1 to A I 3; and 0.76, 0.61 and 0.78 for E N V 1 to E N V 3.Graphic output of the two TAM models
