Abstract: This paper is about the development and validity testing of a context-sensitive measure of the effectiveness of multidisciplinary emergency management teams that coordinate the multidisciplinary assistance on an incident scene. The scale can assist in future research, and serve as an instrument to evaluate team effectiveness during not only actual incidents but also emergency management exercises and training programmes. After developing the scale, we validated it in a study with a field sample of 50 teams executing realistic emergency management exercises. Results indicate that the scale is internally consistent. We showed construct validity by an assessment of both convergent and discriminant validity. The scale indicates participant-external rater invariance and can be aggregated to a team score. Suggestions are offered for improving the scale, future validity testing, and practical use of the measure.

Keywords: team effectiveness; scale development; validity testing; emergency management teams; multidisciplinary teams; training exercises.
