The objective of this research was to perform the factorial validity of the Maslach Burnout Inventory Human Services (MBI-HSS) in prison officers in Chile through a first-order factor analysis and a confirmatory analysis. The sample was constituted by all the prison officers in the Region of Arica and Parinacota (N=334). Of these, 44 did not participate in the study, since they were in a medical leave, vacation or special permit, transfer in progress, or similar situation. Therefore, the final number of participants was 290 subjects. The Burnout Syndrome (BS) was estimated through the adaptation to Spanish (Gil-Monte, 2005) of the Maslach Burnout Inventory, in its version for human services professionals (MBI-HSS) (Maslach & Jackson, 1986), validated in Chile (Olivares, 2009). By way of conclusion, the present investigation found similarities in the MBI-HSS in terms of dimensionality and reliability analysis, and despite the international observations of the instrument, an adjusted proposal (standardization and validation) of the MBI-HSS is provided for contexts Prisoners with 18 items, since in Chile there is no validation of the MBI-HSS in prison officers.   How to Cite this Article: Álvarez-Cabrera, P., López-Reyes, K., Chacón, F. y Sánchez, E.
