Abstract
BACKGROUND: Recent studies showed that psychological safety is important to resident perception of the work environment, and improved psychological safety improves resident satisfaction survey scores. However, there is no evidence in medical education literature specifically addressing relationships between psychological safety and learning behaviors or its impact on learning outcomes. OBJECTIVE: We developed and gathered validity evidence for a group learning environment assessment tool using Edmondson's Teaming Theory and Webb's Depth of Knowledge model as a theoretical framework. METHODS: In 2018, investigators developed the preliminary tool. The authors administered the resulting survey to neonatology faculty and trainees at Baylor College of Medicine morning report sessions and collected validity evidence (content, response process, and internal structure) to describe the instrument's psychometric properties. RESULTS: Between December 2018 and July 2019, 450 surveys were administered, and 393 completed surveys were collected (87% response rate). Exploratory factor analysis and confirmatory factor analysis testing the 3-factor measurement model of the 15-item tool showed acceptable fit of the hypothesized model with standardized root mean square residual = 0.034, root mean square error approximation = 0.088, and comparative fit index = 0.987. Standardized path coefficients ranged from 0.66 to 0.97. Almost all absolute standardized residual correlations were less than 0.10. Cronbach's alpha scores showed internal consistency of the constructs. There was a high correlation among the constructs. CONCLUSIONS: Validity evidence suggests the developed group learning assessment tool is a reliable instrument to assess psychological safety, learning behaviors, and learning outcomes during group learning sessions such as morning report.
