title: Psychometric analysis of the scale for the predisposition to the occurrence of adverse events in nursing care provided in ICUs.
abstract: OBJECTIVE
  to present the result of the validity and reliability studies concerning the Scale for the Predisposition to the Occurrence of Adverse Events (EPEA).
  
  
  METHODS
  construct validity was based on Principal Components Analysis.
  
  
  RESULTS
  reliability verified through Cronbach's alpha indicated good reliability (structure α=0.80; process α=0.92).
  
  
  CONCLUSIONS
  based on its psychometric indicators, the EPEA can be considered a valid measure to assess the attitudes of nurses in relation to factors that potentially lead to the occurrence of adverse events in ICUs.
