Team level positivity: investigating positive psychological capacities and team level outcomes
研究了团队层面的积极心理能力（如乐观、韧性、效能感）如何影响团队凝聚力、合作、协调、冲突和满意度，发现团队乐观在新组建团队中更重要，而韧性和效能感在多次互动后解释力更强。
Abstract The movement toward positive psychology has uncovered the important role that positivity plays in both individual and organizational success. Given that work teams are becoming increasingly embedded in organizational structures, it is surprising that few researchers have investigated positivity at the team level. The present study examines the emergence of team level positive psychological capacities and their relationship with team outcomes (e.g., cohesion, cooperation, coordination, and conflict and team satisfaction) during two team sessions. Results from 101 teams suggest that team optimism is an important predictor of team outcomes when teams are newly formed, whereas team resilience and team efficacy show greater explanatory power after several team interactions. Implications of the findings are discussed, as well as possible avenues for additional research. Copyright © 2009 John Wiley & Sons, Ltd.
