There is growing evidence on the importance of psychological safety, or how comfortable participants feel in sharing their opinions and ideas in a team, in engineering team performance. However, how to support it in engineering student teams has yet to be explored. The goal of this study was to investigate whether a video intervention with assigned roles could foster psychological safety in student engineering teams. In addition, we sought to explore the impact of the frequency of the videos and the utility of the roles on the self-efficacy of students and the perceived psychological safety of the team. Specifically, this study introduces video interventions and the four lenses of psychological safety (Turn-Taking Equalizer, Point of View Shifter, Affirmation Advocate, and Creativity Promoter), and seeks to determine their effectiveness at increasing psychological safety self-efficacy and individual levels of psychological safety. A pilot study was completed with 54 participants (36 males, 17 females, 1 non-binary/third gender) enrolled in a cornerstone engineering design course. Over 10 weeks, data was collected at 5 time points. The results present four key findings. Most notably, 1) a video educating all students about psychological safety in general was effective in improving psychological safety self-efficacy and students retained this information to the end of the project;2) intervention groups taught to use the four lenses did not have a statistically significant higher level of psychological safety than non- intervention groups; and 3) intervention groups perceived the use of the lenses to increase psychological safety. These results provide a baseline understanding that is needed to support psychological safety including: when to intervene, how to intervene, and how frequently to intervene.

Can We Get an Intervention, Please? The Utility of Teaming Interventions on Engineering Design Student Psychological Safety.
Research on psychological safety has been growing in recent years due to its role in promoting creativity and innovation, among other items. This is because teams with high levels of psychological safety feel safe to express ideas and opinions. While we are becoming more aware of the importance of psychological safety in teaming, there is limited evidence in how to facilitate or build it within teams, particularly in an educational context. This paper was developed to respond to this research void by identifying the impact of teaming interventions aimed at improving psychological safety in engineering design student teams. Specifically, we studied two cohorts of students in a cornerstone design class (N = 414 students), one who received a series of video interventions and introduced role playing (intervention) and one who did not (control). These role assignments — referred to as the Lenses of Psychologically Safety - were created to promote key leadership attributes that have been shown to be crucial in facilitating psychologically safe teams. To compare the utility of the intervention, Psychological Safety was gathered at 5 key time points of a multi-week design project. The results identified three key findings. First, the interventions were successful in increasing psychological safety in engineering teams. In addition, the results indicated the utility of the Lenses of Psychological Safety throughout the design process. Finally, the results identified that groups who used these lenses had higher perceptions of Psychological Safety in their teams. Overall, these results indicated that psychological safety can be improved in engineering education through the intervention methods described within.

A psychologically safe environment is characterized by people who feel safe to voice ideas and concerns, willingly seek feedback, have positive intentions to one another, engage in constructive confrontation, and feel safe to take risks and experiment. Outside of academia, psychological safety has been shown to impact creativity, work performance, and work engagement. In academic research environments, faculty have a major leadership role in cultivating a psychologically safe environment amongst their academic research teams. Effective graduate student mentoring, which includes both career and psychosocial support, is critical to the development and retention of talented engineers in the US workforce. There is a need to better understand how engineering departments can cultivate more inclusive, psychologically safe environments in which graduate students feel safe to engage in interpersonal risk-taking, especially in research settings. Guided by the Conservation of Resources theory, this project aims to address the following research question: What are the relationships between faculty advisor mentoring, doctoral student psychological safety, and the subsequent positive and negative outcomes for doctoral students? This work in progress paper presents the first quantitative phase of an explanatory mixed methods research design within the overarching project. The quantitative phase will address the following research aims: 1) Identify relationships between mentorship, psychological safety, and engineering doctoral student mental health, 2) Identify mentoring competencies that are predictive of research group psychological safety, and 3) Identify how different demographics experience mentoring and psychological safety in their research groups. Researchers developed a survey consisting of five pre-existing scales, four open-ended questions, and demographics questions. The scales include dyadic and team psychological safety, mentoring competency, mental health and well-being, and job stress. The survey was reviewed by graduate students outside of the participant pool at multiple institutions as well as an external advisory board panel and revised to improve clarity and ensure the selection of appropriate subscales. The survey will be administered via Qualtrics. Graduate students who have been enrolled in their doctoral program for at least one year and currently have a doctoral research advisor will be recruited to participate in the survey at four public, research-intensive institutions. The planned target sample size is 200-300 graduate students. This paper will present the design of the survey and preliminary survey results. As the first part of a larger mixed-methods study, the survey responses provide insight into graduate level engineering education and how doctoral students can be better supported.more » « less

Improving team interactions in engineering to model gender inclusivity has been at the forefront of many initiatives in both academia and industry. However, there has been limited evidence on the impact of gender-diverse teams on psychological safety. This is important because psychological safety has been shown to be a key facet for the development of innovative ideas, and has also been shown to be a cornerstone of effective teamwork. But how does the gender diversity of a team impact the development of psychological safety? The current study was developed to explore just this through an empirical study with 38 engineering design student teams over the course of an 8-week design project. These teams were designed to be half heterogeneous (either half-male and half-female, or majority male) or other half homogeneous (all male). We captured psychological safety at five time points between the homogenous and heterogenous teams and also explored individual dichotomous (peer-review) ratings of psychological safety at the end of the project. Results indicated that there was no difference in psychological safety between gender homogenous and heterogenous teams. However, females perceived themselves as more psychologically safe with other female team members compared to their ratings of male team members. Females also perceived themselves to be less psychologically safe with male team members compared to male ratings of female team members, indicating a discrepancy in perceptions between genders. These results point to the need to further explore the role of minoritized groups in psychological safety research and to explore how this effect presents itself (or is covered up) at the team level.more » « less

This paper investigates team psychological safety (N=34 teams) in a synchronous online engineering design class spanning 4 weeks. While work in this field has suggested that psychological safety in virtual teams can facilitate knowledge-sharing, trust among teams, and overall performance, there have been limited investigations of the longitudinal trajectory of psychological safety, when the construct stabilizes in a virtual environment, and what factors impact the building of psychological safety in virtual teams. The results of this study identified that the construct of psychological safety took more time to become a reliable construct in virtual design teams, but once it stabilized, it did not change. Additionally, qualitative findings point to issues with communication and conflict across various stages of the design process in the development of psychological safety. Finally, we identify potential interventions to enhance team mental model development in the early phases of virtual teaming to support team psychological safety.more » « less

Abstract Although teamwork is being integrated throughout engineering education because of the perceived benefits of teams, the construct of psychological safety has been largely ignored in engineering research. This omission is unfortunate because psychological safety reflects collective perceptions about how comfortable team members feel in sharing their perspectives, and it has been found to positively impact team performance in samples outside of engineering. While prior research has indicated that psychological safety is positively related to team performance and outcomes, research related to psychological safety in engineering teams is less established. There is also a lack of comprehensive methodologies that capture the dynamic changes that occur throughout the design process and at each time point. In light of this, the goal of the current study was to understand how psychological safety might be measured practically and reliably in engineering student teams over time. In addition, we sought to identify factors that impact the building and waning of psychological safety in these teams over time. This was accomplished through a study with 260 engineering students in 68 teams in a first-year engineering design class. The psychological safety of the teams was captured for each team over five time points over the course of a semester long design project. The results of this study provide some of the first evidence on the reliability of psychological safety in engineering teams and offer insights as to how to support and improve psychological safety.more » « less
