This study aimed to develop and validate an instrument for nursing triage in
occupational health services (ICEST). Exploratory factor-analysis techniques were used
to remove redundant or non-endorsed items and identify the factor structure of the
ICEST. Validation of the items, content, construct and reliability were also performed.
The final ICEST consisted of 14 indicators and 71-graduated indexes. The ICEST showed to
be reliable, consistent and satisfactory structure to be applied in occupational health
services. keywords: validation studies; occupational health; nursing
