To meet the challenges of rapid advances in client technology, audit standards urge auditors to use computerassisted audit tools and techniques (CAATs). However, recent research suggests that CAAT use is fairly low.This paper uses the Unified Theory of Acceptance and Use of Technology (UTAUT) to identify and then examines factors potentially influencing auditors' use or non-use of CAATs. Examining auditor use of CAATs is important because CAATs hold out the promise of improving audit efficiency and effectiveness. Data was obtained from 181 auditors fromBig 4, national, regional, and local firms. Results indicate that outcome expectations, the extent of organizational pressures and technical infrastructure support influence the likelihood that auditors will use
CAATs.
