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). METHOD: 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). CONCLUSION: 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.
