Abstract: Work teams have been widely adopted in organizations. The objective of this study is to develop a scale measuring the interaction among the members of work teams. A simulated team exercise was used in this study. It was found that the items concerning the team members’ interaction are loaded on two dimensions that are named structural and interpersonal dimensions respectively. The scale has satisfactory reliability. The two dimensions positively correlate with the performance of the investigated work teams, indicating the scale’s strong validity. The developed scale can be used as an instrument to measure the interaction of work-teams in future studies.

Key words: work team, interaction, scale, reliability, validity, team performance
