For many years, studies on Individual Information Technology Acceptance were developed and many models were created according to those studies’ evidences. Some were based on sociology and psychology concepts, imported to technology’s world. Others were a result of already existing Information Technology Acceptance Models with new design and new determinants. All this models intend to know and to define the determinant contributions on the user agreement on Information System and how this value can be a determinant factor to Information System adoption and success. This study focus is on Unified Theory on Users Acceptance and Use on Technology, UTAUT, a synthesis model, and about the contributions it has brought to this area. A survey about Computer Assisted Audit Tools and Techniques, CAATTs, and its acceptance among auditors, using UTAUT as a reference, will be presented. This paper focus is on adding new determinants/moderators to Unified Theory on Users Acceptance and Use on Technology Model and CAATTS, and a study about Portuguese Auditors profile.
