Self- and observer ratings of team reflection: A mixed methods approach

The extent to which self- and observer ratings of team reflection are related and whether the different data sources can explain incremental variance in team performance improvement has not yet been examined. We therefore studied teams working on a hidden profile task. Team reflection was measured using self-reports and audio data. Self- and observer ratings did not correlate with each other but simultaneously predicted team performance improvement. In contrast to self-ratings, observer-rated quality positively predicted performance improvement independent of controlling for observer-rated quantity. Conclusively, both data sources appear to be diagnostically valuable and should be considered when examining team reflection.
