ABSTRACT
INTRODUCTION: Healthcare professionals (HCP)' Burnout Syndrome (BS) has been a major concern, even more amidst the COVID-19 Pandemic. Adequate tools to assess BS are urgent. The objective of this study was the validation of the Brazilian Portuguese version of the Copenhagen Burnout Inventory (CBI) in HCP. METHOD: The sample consisted of 1054 Brazilian HCP. Data were collected for one month (May-2020 to June-2020) through an online self-administered questionnaire. RESULTS: The three CBI dimensions presented optimal reliability. All consistency measures showed values > 0.90. Split-half correlation values with Spearman-Brown reliability were higher than 0.8. The parallel analysis suggested two factors: personal burnout (PB) and work-related burnout (WB) items were associated with factor 1, and client-related burnout (CB) items were associated with factor 2. DISCUSSION: Our study corroborates the validity of the Brazilian Portuguese version of the CBI, pointing to a close relation between PB and WB in HCP. A public domain tool that has the quality of evidence for sufficient content validity can aid in burnout evaluation, and encourage both the expansion of the research field as well as the accurate detection and treatment of this syndrome in Brazilian HCP.
