The non-user model proposes that Perceived Support, P S, influences Perceived Ease of Use, P E U, under H 1. Environment, E N V, influences Perceived Ease of Use under H 2. Perceived Ease of Use influences Perceived Usefulness, P U, under H 3, Attitude of Adoption, A A, under H 4 a, and Adoption Intention, A I, under H 5 a. Perceived Usefulness influences Attitude of Adoption under H 4 b and Adoption Intention under H 5 b. Environment influences Adoption Intention under H 5 c. Attitude of Adoption influences Adoption Intention under H 5 d. The user model presents the same relationships. Support Quality, S Q, replaces Perceived Support, and Adoption Decision, A D, replaces Adoption Intention.Theoretical model proposed for users and non-users
Note: The model differentiates between non-users (evaluating perceived support PS and intention to adopt AI) and users (evaluating experienced support quality SQ and actual adoption decision AD)
