Abstract
From the previous research on perfectionism, perfectionism is considered as two facets-adaptive perfectionism and maladaptive perfectionism, also considered as positive perfectionism and negative perfectionism, respectively. In this study, we examine the congruence effect of a leader’s and members’ adaptive perfectionism on team exhaustion, which in turn influences team performance-innovativeness and constraint adherence. Using data from 63 R&D teams in Taiwan, results of polynomial regressions supported the incongruence effect hypothesis that team exhaustion was higher when a leader and members had incongruent adaptive perfectionism rather than those had congruent adaptive perfectionism. Further, incongruence effects were found that team exhaustion is lower when a leader’s adaptive perfectionism was lower than members’ adaptive perfectionism rather than when a leader’s adaptive perfectionism was higher than members’ adaptive perfectionism. The implications of the review for future researcher and practices are also discussed.
