Scale Properties of the Team Role Self‐Perception Inventory

We present an analysis of the dimensionality of the scales that assess the nine team roles contained in the Team Role Self‐Perception Inventory. Using a data set of over 14,000 respondents, reasonable fit to seven‐item unidimensional factor models was obtained for all scales except Implementer and Specialist. Two‐factor structures for all scales showed improvements in model fit although for all roles a small and unreliable second factor was found. Bi‐dimensional structures reflect the separate loading of negatively worded items and/or different item content areas. Five‐item scales provide a more economical version of the inventory and areas for further development of the instrument are identified.
