Many organizations are using computer-mediated communication to facilitate group work among virtual teams. However, little is known about the effects of using computer-mediated communication on team member outcomes. Examining use of computer-mediated communication as a continuum, the authors found that team members who used computer-mediated communication more often experienced lower levels of positive affect while working with their teams and had lower levels of affective commitment to their teams. Positive affect mediated the relationship between use of computer-mediated communication and affective commitment. Moreover, this study identified a tipping point (using computer-mediated communication more than 90% of the time) at which the use of computer-mediated communication was particularly detrimental to team outcomes.
