CRIES: a new neonatal postoperative pain measurement score. Initial testing of validity and reliability

Paediatr Anaesth. 1995;5(1):53-61. doi: 10.1111/j.1460-9592.1995.tb00242.x.


We have developed a neonatal pain assessment tool CRIES. The tool is a ten point scale similar to the APGAR score (Apgar 1953). It is an acronym of five physiological and behavioural variables previously shown to be associated with neonatal pain. C--Crying; R--Requires increased oxygen administration; I--Increased vital signs; E--Expression; S--Sleeplessness. We have tested CRIES for validity and reliability. This report is the result of that testing. We have found CRIES to be valid, reliable and well accepted by neonatal nurses.
