Despite the clear relevance of stressors for the creative work performed by individuals, how they affect teams in their ability to innovate is poorly understood. Thus, the question as to what kind of, and by which mechanisms, team stressors may give rise to better innovation team performance needs further consideration. We address this issue by applying the challenge–hindrance stressor framework to the team level of analysis in the context of innovation teams. By integrating insights from social identity theory and the attentional focus model, we highlight the importance of identity‐ and information‐based mechanisms in transmitting the differential effects of challenge and hindrance team stressors on the performance of innovation teams. We test our arguments for two of the most prominent indicators of innovation team performance (i.e., team creativity and team efficiency) in a multi‐informant sample of team members, team‐internal leaders, and team‐external managers from 114 innovation teams. Our findings support the opposing effects of challenge and hindrance team stressors in predicting innovation team performance through the two differential mechanisms. Specifically, for team efficiency, both team stressors come with the cost of team task conflict (i.e., the information‐based mechanism). However, whereas challenge team stressors enhance collective team identification (i.e., the identity‐based mechanism), hindrance team stressors undermine collective team identification, thereby aggravating their already negative effect on team efficiency. In terms of team creativity, our results suggest that both types of team stressors exert their indirect effects solely via the identity‐based mechanism. Implications for research and practice are discussed.
