Technology acceptance models have been an important area of research in the Information Systems arena, especially in the last 20 years. This study integrates factors from four models related to the acceptance of mobile computing into a new model termed the Integrated Technology Acceptance Model for Mobile computing (ITAMM). Most technology acceptance studies use factors from Davis's Technology Acceptance Model (TAM), Davis and Venkatesh's Extended Technology Acceptance Model (TAM2), Ajzen's Theory of Planned Behavior (TPB), and/or Goodhue's Task-Technology Fit (TTF) work. Using the definitions of each component in these models, the research assesses which factors should be extracted into an integrated technology acceptance model for mobile computing devices. Subsequent interviews of PDA users resulted in the identification of three additional factors for the integrated model. The factors are adaptability, mobility, and security. This paper presents the ITAMM and the results of multiple regressions analyses for the new model.
