Factorial Validity of the "Spanish Burnout Inventory" among Portuguese Police Officers

This study was designed to assess the factor structure and the internal consistency of the Portuguese adaptation of the "Spanish Burnout Inventory" (SBI) in a sample of 245 Portuguese police officers working in Lisbon. Using an Exploratory Factor Analysis (EFA), 4 factors were extracted with eigenvalue > 1, reproducing the original model: the first factor was constituted by the items of "enthusiasm toward the job", the second factor was constituted by the items of "guilt", the third factor was constituted by the items of "indolence", and the fourth factor was constituted by the items of "psychological exhaustion". Internal consistency values for all subscales showed values of Cronbach's alpha higher than.70. The results suggest that the Portuguese adaptation of the SBI is an adequate instrument to assess burnout in Portuguese police officers.
