This study aims to explore psychological safety as a potential moderating mechanism for the relation between functional diversity and individual perceptions of learning, and functional diversity and team performance in self-assembled teams.

To test these relationships, the authors conducted a cross-level, time-lagged, quasi-experiment, using a sample of 143 self-assembled teams. In one condition, participants formed into functionally diverse teams, and in another condition, participants formed functionally homogeneous teams.

Results suggest that functional diversity and psychological safety have an interactive effect on both individual learning and self-assembled team performance, albeit in different directions. Specifically, low psychological safety was more deleterious for individuals on functionally diverse teams than functionally homogeneous teams when it came to perceptions of learning, but the opposite was true when it came to team performance.

The results of this study indicate that it is critical to train team members on developing psychological safety, both in traditional and functionally diverse contexts.

To investigate the factors affecting innovation in Six Sigma improvement teams. Based on Activation Theory, this study explores the possibility of an inverted U-shaped association between psychological safety and innovation and examines how intrinsic motivation moderates this relationship.

Moderated regression analysis is carried out to test the curvilinear relationship, using data collected from 324 members of 102 Six Sigma improvement teams from two European manufacturing firms.

The findings demonstrate that the beneficial effect of psychological safety reaches an inflection point, after which its relations with innovation cease to be linear and positive; this gives the relationship a curvilinear pattern (inverted U-shaped). Further, intrinsic motivation has a supportive effect in enhancing the beneficial impact of psychological safety on innovation, and in shifting the inflection points to a higher level; this demonstrates their synergetic influence on innovation.

The impact of psychological safety on innovation is examined from the new perspective of a curvilinear relationship. This is one of the first studies to investigate the combined effects of individual (intrinsic motivation) and team-level antecedents (psychological safety) on innovation in Six Sigma teams. The study provides insights into how Six Sigma enhances innovation and offers some valid inputs to the current academic debate on this topic.

This study examines the effect of the spiritual leadership of the leaders in a consulting team on psychological safety climate and team innovation. Moreover, our research adopts the contingency theory of leadership to investigate whether the effect of spiritual leadership on psychological safety climate and team innovation could be moderated by personal characteristics of team members in terms of occupational self-efficacy.

Survey data were obtained from 229 team members across 24 consulting firms in Bangkok. To minimize common method bias, team innovation was assessed by team leaders while other variables were assessed by team members. We used Partial Least Squares Structural Equation Modeling to analyze the data.

The analysis supports the positive effect of spiritual leadership on psychological safety climate and team innovation. Psychological safety climate also mediates the effect of spiritual leadership on team innovation. Lastly, the moderating effect analysis shows that the spiritual leadership of the team leaders exerts a weaker influence on the psychological safety climate and team innovation when team members exhibit high levels of occupational self-efficacy.

Because spiritual leadership plays a significant role in boosting team innovation through the creation of a psychologically safe climate, the consulting firms can provide a leadership development program to help their team leaders to gain insight into the nature of spiritual leadership and learn how to demonstrate appropriate behaviors when they supervise a team. In particular, this policy recommendation is highly relevant when team leaders supervise members who exhibit low occupational self-efficacy.

Our findings not only illustrate that spiritual leadership could enhance team innovation through the mediating role of psychological safety climate, but the level of occupational self-efficacy of the team members could significantly reduce the effects of spiritual leadership on psychological safety climate and team innovation.

Mobile messaging groups (MMGs) have been widely adopted in construction practice, yet, little is known about how to foster knowledge sharing (KS) in MMGs, characterized by communication visibility. This study is thus motivated to investigate mechanisms for KS in this context.

The paper employs knowledge governance theory to construct a theoretical model and develop hypotheses. Specifically, psychological safety is identified as a mediator between knowledge governance mechanism (KGM) and KS, and promotion regulatory focus is identified as a moderator between KGM and psychological safety. Data from 208 Chinese construction project team members are collected to test the proposed theoretical model.

The results suggest that both formal and informal KGM positively affect psychological safety, which in turn improves KS (quantity and quality). Moreover, the mediating role of psychological safety is confirmed, and the moderating role of promotion regulatory focus is validated.

This study explores how to foster KS in MMGs, which are pervasive in today’s digital age. The findings in this study enhance the understanding of KS in digital environments and afford important insights into knowledge management within construction project teams.

The study investigated the predictive role of supportive leadership and psychological safety for mindful organizing and the subsequent impact of mindful organizing on individual task performance. Mindful organizing, a concept from high-reliability organizations (HROs), can improve performance in various industrial settings. The limited availability of novel predictors for mindful organizing necessitates exploring this concept in the context of adventure tourism.

Through a cross-sectional research approach, 394 respondents were selected from the adventure tourism industry in Malaysia. The proposed causal research model was evaluated through structural equation modeling (SEM), aggregation and bootstrapping.

Psychological safety and supportive leadership significantly impacted mindful organizing. Mindful organizing, in turn, was positively associated with individual task performance. The mediating role of mindful organizing between psychological safety and task performance was statistically significant. However, the mediating role of mindful organizing between supportive leadership and task performance was not statistically significant.

Managers in the adventure tourism industry should consider applying mindful organizing to increase employee productivity and develop collective sensemaking. Also, developing a culture of support among managers and coworkers, emphasizing the team's psychological safety, may boost the morale and productivity of the workforce.

This research has identified and empirically tested new antecedents, psychological safety and leadership for mindful organizing in the adventure tourism context and has addressed a significant research gap (Sutcliffe et al., 2016) by broadening the scope of mindful organizing research to encompass contexts beyond those exclusively considered HROs.

Research focusing on psychological capital (PsyCap) has been mainly conducted at the individual level. However, recent research has expanded investigations to the collective level with a greater focus on team-level PsyCap. Although, as demonstrated by recent systematic reviews and meta-analyses, the relationships between individual-level PsyCap and the desirable/undesirable outcomes are fairly established in the literature, less is known about such relationships for team-level PsyCap. One of these important, yet least investigated, research areas is the research stream that focuses on the relationship between team-level PsyCap and the outcomes of health, Well-Being, and safety. This chapter aims to highlight the role of individual-level PsyCap as an important predictor of employees’ health, Well-Being, and safety outcomes, but also to go beyond that to provide insights into the potential role of team-level PsyCap in predicting such outcomes at both individual and team levels. To do so, the chapter first draws upon relevant theories to discuss the empirical research findings focusing on the relationship between individual-level PsyCap and the outcomes of health, Well-Being, and safety. It then focuses on team-level PsyCap from theoretical, conceptualization, and operationalization perspectives and provides insights into how team-level PsyCap might be related to health, Well-Being, and safety outcomes at both individual and team levels. Thus, this chapter proposes new research directions in an area of PsyCap that has been left unexplored.

Drawing upon the theory of communication visibility, this research intends to investigate the direct effect of enterprise social media (ESM) usage on team members’ knowledge creation capability (KCC) and the mediating effects of psychological safety and team identification. In addition, it aims to untangle how the efficacy of ESM usage varies between pre- and post-COVID-19 periods.

Using two-wave survey data from 240 members nested within 60 teams, this study utilizes a multilevel approach to test the proposed hypotheses.

We discover that ESM usage enhances team members’ KCC. More importantly, the results show that psychological safety and team identification mediate the ESM–KCC linkage. Interestingly, we further find that the impacts of ESM usage on team members’ KCC, psychological safety, and team identification are stronger in the pre-COVID-19 period than those in the post-COVID-19 period.

This research sheds light on the ESM literature by unraveling the mechanisms of psychological safety and team identification underlying the linkage between ESM usage and team members’ KCC. Moreover, it advances our understanding of the differential efficacy of ESM usage in pre- and post-COVID-19 periods.

New product development (NPD) projects are strategically important for firms’ operations but suffer from high failure rates. Leadership is a key factor for project success. However, in contrast to positive project leadership, project managers’ knowledge hiding has received little attention. Drawing on the input-mediator-output (IMO) framework and model of work team resilience, we explored the effect of project managers’ destructive knowledge hiding (i.e. evasive hiding and playing dumb) on project team performance (i.e. efficiency and effectiveness) and the serial indirect effect through team psychological safety and transactive memory systems.

We conducted a time-lagged multiple-sourcing investigation of Chinese high-tech firms and tested the hypotheses using data collected from 105 NPD project teams.

Our findings demonstrated that project managers’ knowledge hiding negatively affects NPD project team performance and indirectly negatively affects transactive memory systems through team psychological safety. Moreover, project managers’ knowledge hiding exerts a negative indirect effect on team performance through team psychological safety and transactive memory systems in serial.

This study contributes to the literature on operations management (OM) by broadening our understanding of the connection between project managers' destructive knowledge hiding and the failure of NPD projects. In providing such insight, it also offers practical guidance for overcoming team-level obstacles arising from project managers' knowledge hiding.

Based on social influence theory, this paper aims to explore the influence of academic entrepreneurs on team innovation activities. The innovation behavior of academic team members is the key behavior in academic entrepreneurial activities. As a special entrepreneurial group, academic entrepreneurs' political skills play an important role in stimulating team innovative behaviors.

This paper adopts a multi-level study design and takes as samples the paired data of 91 academic entrepreneurial teams (n = 475). Based on team cognition, it constructs a model of the influence mechanism of academic entrepreneurs' political skills on team innovation behavior and explores the mechanism of transactive memory system in this influence effect. The authors use HLM and PROCESS macro to test our multilevel model.

The results show that academic entrepreneurs' political skills positively impact team innovation behavior, and a transactive memory system plays a mediating role between them. Team psychological safety significantly enhances the positive relationship of both academic entrepreneurs' political skills and a transactive memory system with team innovation behavior. Moreover, with enhanced perceptions of team psychological safety, academic entrepreneurs' political skills are more likely to improve team innovation behavior through the transactive memory system.

The study explores the influence of transactive memory system on the relationship between academic entrepreneurs' political skills and team innovation behavior, with the team cognitive perspective derived from social influence theory. This provides authors with new insights on the complex dynamics at place in the team innovation process and offers implications for how we can fruitfully manage this process.

The present study aims to advance a new framework to spur creativity at individual and team levels in the construction industry by studying a leader's sense of humor. The authors develop and test a multi-level model to investigate the direct and indirect effects of leader's humor on creativity within teams working on construction projects. The authors draw on the benign violation theory to hypothesize that a leader's sense of humor influences the acceptability of norm violations in teams, which helps to improve their creativity. The authors also integrate the benign violation theory with the social information processing theory to examine the indirect effects of project leader's sense of humor on individual- and team-level creativity via team psychological safety.

The authors collected data from 165 members nested in 45 teams working on construction projects in China. The construct's factor structure and discriminant validity were established through confirmatory factor analysis. The authors used multi-level modeling via Mplus to test team-level to the individual-level direct and indirect hypotheses, while team-level direct and indirect hypotheses were tested using ordinary least squares regression.

The results show that the leader's humor has a dual positive direct effect on individual and team creativity. Furthermore, these effects are partially mediated by team psychological safety. The implications of these findings to improve the construction management theory and practice are discussed in the manuscript.

The current study contributes to the literature by understanding the significance of leader humor in predicting individual-level and team-level creativity within the construction sector. It expands the literature by examining team psychological safety as the underlying mechanism in the relationship between leader humor and creativity.
