Reliability test of a smartphone-based measurement tool for the United States general surgical trainees’ intraoperative performance using multivariate generalizability theory: a psychometric study

The System for Improving and Measuring Procedure Learning (SIMPL), a smartphone-based operative assessment application, was developed to assess the intraoperative performance of surgical residents. This study aims to examine the reliability of the SIMPL assessment and determine the optimal number of procedures for a reliable assessment.
