[Validation of the Copenhagen Burnout Inventory to assess professional burnout in Spain].

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. METHOD: 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.

Fiabilidad y validez del Copenhagen Burnout Inventory para su uso en España / Validation of the Copenhagen Burnout Inventory to assess professional Burnout in Spain

Fundamentos: El cuestionario Copenhagen Burnout Inventory (CBI) es de dominio público para la medida del síndrome de burnout, que está estructurado en tres subdimensiones: la personal, la relacionada con el trabajo y la relacionada con el trabajo con clientes. El objetivo de este trabajo es determinar la aceptabilidad, fiabilidad y validez de su traducción al español. Método: La población de estudio fueron 479 trabajadores de la enseñanza, trabajo social, sanidad e industria. Tras el proceso de traducción y retrotraducción, en 2009 se procedió a estudiar las características del cuestionario que incluía las tres escalas de CBI, dieciséis de ambiente psicosocial (COPSOQ ISTAS21) y tres de SF-36. Resultados: La tasa de respuesta fue del 78,7%. Las tres escalas presentaron una correlación inter-ítem entre 0,42 y 0,60 y una correlación ítem-total corregida entre 0,49 y 0,83. La consistencia interna de las tres escalas de burnout tuvo valores de α de Cronbach de 0,90 en el personal, 0,83 en la dimensión relacionada con trabajo y 0,82 en la relacionado con el trato conclientes. Conclusiones: Las puntuaciones de burnout se relacionaron con el entorno psicosocial del trabajo y con las medidas de salud y bienestar en la dirección e intensidad esperadas. Los ítems de las tres escalas presentan una buena capacidad de discriminación, consistencia y homogeneidad. La capacidad de discriminación también se observa en los distintos niveles de burnout entre ocupaciones y actividades. La validez de constructo queda acreditada. Estos resultados demuestran que la versión en castellano de CBI que se presenta es un instrumento fiable y válido para la medida específica de burnout en España (AU)

[Psychosocial risk exposure among wage earning population in Spain (2004-05): reference values of the 21 dimensions of COPSOQ ISTAS21 questionnaire]. / Exposición a riesgos psicosociales entre la población asalariada en España (2004-05): valores de referencia de las 21 dimensiones del cuestionario COPSOQ ISTAS21.

BACKGROUND: Reference values of all the 21 psychosocial scales or dimensions (73 items) of the psychosocial risk assessment questionnaire COPSOQ ISTAS21 are computed from a representative sample of the wage earning population in Spain. METHODS: Representative sample of the Spanish wage-earning population, n=7,612. The sampling was multi-stage by conglomerates. The information was obtained by the administration of a standardized questionnaire in the household during 2004-2005. All 21 scales were standardized and three punctuation levels were established and labelled as 'more favourable to health (or green)', 'intermediate (or yellow)' and 'more unfavourable to health (or red)' according two criteria: 1) to obtain groups that follow a tertiles theoretical distribution and 2) to get the 'red' and 'green' groups as equilibrated as possible. RESULTS: Response rate was 60. Predictability dimension showed the wider difference between 'green' and 'red' proportions (7.14). Role clarity concentred the 35.06 % of population between 100 and 93.75 points, and Sense of community the 29.6% between 100 and 91.67. Double presence and hiding emotions grouped the 34.02% and the 27.74% % of population between 0 and 12.5 points, respectively. CONCLUSIONS: 2005 upgraded representative reference values of the 21 COPSOQ ISTAS21 psychosocial dimensions for the wage earning population in Spain are available, necessary premise to diagnose risk situations and prioritize the needed preventive actions at company level.
