Facilitators are encouraged to get all meeting attendees to participate in the meeting. There is the assumption made that, if they do participate, then this participation will increase the group's general satisfaction of the meeting. Also, knowing the factors that can increase the probability of a successful meeting has been a focus of previous research, yet attendee participation has not been studied. The current research study empirically examines participation's effect on meeting evaluations. This study is a field experiment conducted in a team-based organization, where successful meetings are critical. Data was collected on the amount of participation of team members in their weekly team meeting and their evaluations of the meeting. After running correlations and a principal components analysis, this study found a relationship between participation and meeting evaluations. A scale of meeting success was also created.
