- Leader humility and team performance: exploring the mechanisms of team psychological capital and task allocation effectivenessPublication . Rego, Armênio; Owens, Bradley; Yam, Kai Chi; Bluhm, Dustin; Cunha, Miguel Pina e; Silard, Anthony; Gonçalves, Lurdes; Martins, Mafalda; Simpson, Ace Volkmann; Liu, WenxingAlthough there is a growing interest toward the topic of leader humility, extant research has largely failed to consider the underlying mechanisms through which leader humility influences team outcomes. In this research, we integrate the emerging literature of leader humility and social information processing theory to theorize how leader humility facilitates the development of collective team psychological capital, leading to higher team task allocation effectiveness and team performance. While Owens and Hekman (2016) suggest that leader humility has homogeneous effects on followers, we propose a potential heterogeneous effect based on the complementarity literature (e.g., Tiedens, Unzueta, & Young, 2007) and the principle of equifinality (leaders may influence team outcomes through multiple pathways; Morgeson, DeRue, & Karam, 2010). In three studies conducted in China, Singapore, and Portugal, including an experiment, a multisource field study, and a three-wave multisource field study, we find support for our hypotheses that leader humility enhances team performance serially through increased team psychological capital and team task allocation effectiveness. We discuss the theoretical implications of our work to the leader humility, psychological capital, and team effectiveness literatures; and offer suggestions for future research.
- Conveyed leader PsyCap predicting leader effectiveness through positive energizingPublication . Rego, Arménio; Yam, Kai Chi; Owens, Bradley P.; Story, Joana S. P.; Cunha, Miguel Pina e; Bluhm, Dustin; Lopes, Miguel PereiraWhereas past research on psychological capital (PsyCap) has tended to focus on how one's self-attributed PsyCap affects one's work behaviors, we extend this literature by examining the concept of conveyed PsyCap and its downstream consequences, above and beyond the influence of self-attributed PsyCap. Drawing from the emotions-as-social-information model, we tested a model of conveyed leader PsyCap predicting leader effectiveness through team positive energizing. A laboratory experiment and a multisource study provided support for our hypotheses. We furthermore found that a leader's within-team consistency in conveyed PsyCap moderates these effects, such that leaders who are more consistent in conveyed PsyCap are rated by followers as better leaders, via the mediating effect of team positive energizing. A post hoc analysis further suggests that conveyed PsyCap is more consistent when conveyed PsyCap is congruent with self-attributed PsyCap. Our work contributes to a better understanding of the underlying mechanisms that make leaders with greater conveyed PsyCap more effective and advances the conceptualization and measurement of PsyCap.
