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.
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).
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%.
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.
哥本哈根倦怠量表（CBI）是一种可公开获取、有效且可靠的倦怠测量工具，包含19个项目，分布在以下3个领域（因子）：个人倦怠、工作倦怠和患者倦怠。本研究的主要目的是确定简化版CBI评估急诊医学住院医师倦怠情况的有效性和可靠性。
这项横断面研究使用了2021年美国急诊医学委员会在职考试后收集的CBI数据。先进行探索性因子分析（EFA），然后进行验证性因子分析（CFA）。
在8491名符合条件的住院医师中，7225名（85.1%）完成了调查；EFA队列包括3613名住院医师，CFA队列包括3612名住院医师。EFA显示有2个特征值≥1，一个内部因子和一个外部因子。有6个CBI项目对这2个因子有贡献。第一个因子与个人倦怠和工作相关倦怠有关，第二个因子与与患者共事有关。有4个CBI项目对内部因子有贡献，2个CBI项目对外部因子有贡献。使用简化版CBI，住院医师出现一种或两种倦怠类型的发生率为34.1%。
本研究为使用6项、2因子的简化版CBI提供了有效性证据和可靠性支持。一个更简短、可靠、有效且可公开获取的倦怠量表为急诊医学中的倦怠研究提供了诸多优势。
