Evaluating an Abbreviated Version of the Circumplex Team Scan Inventory of Within-Team Interpersonal Norms

The Circumplex Team Scan (CTS) assesses the degree to which a team's interaction/communication norms reflect each segment (16th) of the interpersonal circle/circumplex. We developed and evaluated an abbreviated 16-item CTS-16 that uses one CTS item to measure each segment. Undergraduates (n = 446) completing engineering course projects in 139 teams completed the CTS-16. CTS-16 items showed a good fit to confirmatory structural models (e.g., that expect greater positive covariation between items theoretically closer to the circumplex). Individuals' ratings sufficiently reflected team-level norms to justify averaging team members' ratings. However, individual items' marginal reliabilities suggest using the CTS-16 to assess general circumplex-wide patterns rather than specific segments. CTS-16 ratings correlated with respondents' and their teammates' ratings of team climate (inclusion, justice, psychological safety). Teams with more extraverted (introverted) members were perceived as having more confident/engaged (timid/hesitant) cultures. Members predisposed to social alienation perceived their team's culture as relatively disrespectful/unengaged, but their teammates did not corroborate those perceptions. The results overall support the validity and utility of the CTS-16 and of an interpersonal circumplex model of team culture more generally.
