Adoption and Use of Computer-Based Voice Over Internet Protocol Phone Service: Toward an Integrated Model

This study examines factors influencing adoption and use of computer-based voice over Internet protocol (VoIP) phone service and attempts to integrate 2 theoretical approaches: the technology acceptance model (TAM) and the uses and gratifications framework. Using data from an online survey of VoIP users (N = 420), structural equation modeling analyses revealed that perceived ease of use had a significant impact on perceived usefulness. In addition, perceived usefulness had a positive effect on actual VoIP use. The study further discovered that motivations for communication and instrumental use significantly affected perceived ease of use, perceived usefulness, and actual VoIP use. This study suggests that integration of TAM and uses and gratifications can be fruitful in understanding user acceptance of new communication technologies.
