title: [Validation of the Copenhagen Burnout Inventory to assess professional burnout in Spain].
abstract: BACKGROUND
  The Copenhagen Burnout Inventory (CBI) is a public domain questionnaire measuring the degree of psychological fatigue experienced in three subdimensions of Burnout: personal (PB), work-related (WB), and client-related Burnout (CB). The study aimed to examine the acceptability, reliability and construct validity of the Spanish version of CBI.
  
  
  METHODS
  The study population consisted of 479 workers of educational centers, social work centres, healthcare centres and workers within the industry sector. Data was collected in 2009 through a self-administered questionnaire including the three CBI scales, sixteen scales of psychosocial work environment (COPSOQ ISTAS21) and perceived general and mental health and vitality (SF-36).
  
  
  RESULTS
  Response rate was 78.7%. The three scales have an inter-item correlation average between 0.42 and 0.60 and a corrected item-total correlation between 0,49 and 0,83. The internal consistency of the three scales had Cronbach's α values of 0.90 for PB, 0.83 for WB and 0.82 for CB.
  
  
  CONCLUSIONS
  Burnout was related to both psychosocial work environment and wellbeing measures in the expected direction and intensity. The items of the three scales show good discrimination capacity, good consistency and homogeneity. The three CBI scales have an acceptable internal consistency reliability index, slightly higher in PB. The discrimination capacity of the scales is verified through the discrimination index and the different levels between occupations and activities. These results demonstrate that the Spanish version of the CBI is a reliable and valid instrument for measuring Burnout.
