Developing and validating a tool for measuring the educational environment in clinical anesthesia.

Abstract

We aimed to develop a contemporary measure for anesthesia teaching and learning in the operating theatre that was applicable to a variety of training jurisdictions, the Measure for the Anaesthesia Theatre Educational Environment (MATE). A systematic review of the literature and modified Delphi approach was used to identify items for content validity. Reliability and exploratory factor analyses were conducted after a pilot survey of trainees to show construct validity, with removal of redundant items. Item domains were identified through a global assessment of factor structure accuracy and relation to real-world constructs. Literature review generated an initial 73-item list. A modified Delphi approach with 24 experts identified 44 relevant items. The pilot survey generated 390 responses. Reliability analysis, exploratory factor analysis, and global assessment refined the measure to 33 items. Four domains were identified according to factor structure: teaching preparation and practice, assessment and feedback, procedures and responsibility, and overall atmosphere. The educational environment was rated by trainees at 74.6 ± 15.6% with excellent internal consistency (Cronbach's α = 0.975). The MATE survey tool generated valid and reliable scores when measuring the educational environment in the operating theatre. Further research is required to investigate possible differences between the training countries and age of junior doctors and the associated underlying factors. Other researchers are invited to administer the survey and share results within a central database.
