Psychometric properties of the Maslach Burnout Inventory in healthcare professionals, Ancash Region, Peru

Abstract

Background: Burnout syndrome (BS) among healthcare professionals in Peru demands immediate attention. Consequently, there is a need for a validated and standardized instrument to measure and address it effectively. This study aimed to determine the psychometric properties of the Maslach Burnout Inventory (MBI) among healthcare professionals in the Ancash region of Peru. Methods: Using an instrumental design, this study included 303 subjects of both sexes (77.56% women), ranging in age from 22 to 68 years (M = 44.46, SD = 12.25), selected via purposive non-probability sampling. Appropriate content validity, internal structure validity, and item internal consistency were achieved through confirmatory factor analysis, and discriminant validity for the three dimensions was obtained. Evidence of convergent validity was found for the Emotional Exhaustion (EE) and Personal Accomplishment (PA) dimensions, with reliability values (ω > .75). Results: The EE and PA dimensions exhibited acceptable levels of reliability (ω and α > .80). However, the Depersonalization (DP) dimension demonstrated significantly lower reliability (α < .60 and ω < .50). Conclusions: A correlated three-factor model was confirmed, with most items presenting satisfactory factor loadings and inter-item correlations. Nonetheless, convergent validity was not confirmed for the DP dimension.

“…58 Therefore, 63 cases were removed to obtain a final database consisting of 303 participants, which allowed for a better estimation in the conducted statistical analyses. 88 It's crucial to mention that the sample size achieved in this study surpasses the suggested minimum of 300 cases for studies utilizing factor analysis. 76 ).…”

Prevalence and factors associated with burnout syndrome in Peruvian health professionals before the COVID-19 pandemic: A systematic review

“…For example, the Copenhagen Burnout Inventory, which assesses personal, work-related, and client-related burnout [ 72 ]; the Oldenburg Burnout Inventory, which assesses exhaustion and detachment from work [ 73 ]; and other instruments that are less commonly used in the development of research on BS. However, a review found that the MBI is currently the most widely used instrument [ 74 ], and several studies have demonstrated its psychometric properties [ 40 , 75 , 76 ], so we believe that using only the MBI is justified. Finally, the studies found used different versions of the MBI and different cut-offs to determine levels and dimensions of burnout.…”
