In order to communicate well, hospital workers must feel psychologically safe enough within their team to address questions, problems, and errors, and must feel free to make suggestions and give feedback. This study investigates, by the means of a survey on psychological safety and network ties, whether social network ties within and between teams can predict the psychological safety of hospital workers, as they work with colleagues outside of their team as well. Asking for advice from (different) team members and being friends with team members was hypothesised to indicate that the team psychological safety is adequate. Having difficulties with team members was expected to lower the perception of psychological safety. Over the course of three weeks, 70 hospital workers answered the survey via Mechanical Turk and the results from the linear regressions suggest that advice ties positively affect and difficulty ties negatively affect team psychological safety, but only when psychological safety scores were at the lower end of the scale. Team tenure did not moderate the effect that network ties have on psychological safety while larger team sizes may weaken this effect. Future tools for improving psychological safety in hospital teams can make use of the knowledge that advice ties and difficulty ties are possible ingredients of a low psychological safety team moving to a desired level of psychological safety.Show less
