Team Performance: Evidence for Validity of a Measure

Abstract

Abstract This study aimed to obtain validity evidences of a teamwork performance scale. Team performance was understood as a meso-level characteristic, resulting of an emerging process. Due to that understanding the proposed instrument should take that aspect into consideration. The empirical data were collected from 276 Ecuadorian teachers organized in 70 educational teams. They answered nine sentences of the scale. Results of exploratory factor analysis showed a unifactorial solution explaining 65.84% of the variance. The measure also has adequate values of reliability (Cronbach Alpha = .93). In addition to these analyses, patterns of variance within and between the groups were verified. The results showed that the variance at the individual level was small when answers of team members were analyzed and was significant when teams were compared. We consider it is important that additional studies be performed in order to identify stability of the factor solution.
