    Objective: The Copenhagen Burnout Inventory (CBI) is an open-access, valid, and reliable instrument measuring burnout that includes 19 items distributed across the following 3 domains (factors): personal burnout, work burnout, and patient burnout. The primary objective of this study was to determine the validity and reliability of an abbreviated CBI to assess burnout in emergency medicine residents. Methods: This cross-sectional study used data from the CBI that followed the 2021 American Board of Emergency Medicine In-training Examination. Exploratory factor analysis (EFA) was followed by confirmatory factor analysis (CFA). Results: Of the 8491 eligible residents, 7225 (85.1%) completed the survey; the EFA cohort included 3613 residents and the CFA cohort included 3612 residents. EFA showed 2 eigenvalues ≥1, an internal factor and an external factor. There were 6 CBI items that contributed to the 2 factors. The first factor was related to personal burnout and work-related burnout and the second factor was related to working with patients. There were 4 CBI items that contributed to the internal factor and 2 CBI items that contributed to the external factor. Using the abbreviated CBI, the incidence of a resident having 1 or both types of burnout was 34.1%. Conclusions: This study provides validity evidence and reliability support for the use of a 6-item, 2-factor abbreviated CBI. A shorter, reliable, valid, and publicly accessible burnout inventory provides numerous advantages for burnout research in emergency medicine.
