All 4 faces pain scales were found to be adequately supported by psychometric data .
When given a choice between faces scales , children preferred the WBFPRS .
Confounding of pain intensity with affect caused by use of smiling and crying anchor faces is a disadvantage of the WBFPRS .
: For clinical use , we found no grounds to switch from 1 faces scale to another when 1 of the scales is in use .
CONTEXT : Numerous faces scales have been developed for the measurement of  pain intensity in children .
It remains unclear whether any one of the faces scales is better for a particular purpose with regard to validity , reliability , feasibility , and preference .
OBJECTIVES : To summarize and systematic ally review faces pain scales most commonly used to obtain self-report of pain intensity in children for evaluation of reliability and validity and to compare the scales for preference and utility .
Pain, distress, and adult-child interaction during venipuncture in pediatric oncology: an examination of three types of venous access.
This study examined pain and distress from needles in children undergoing blood sampling as a function of  adult-child interaction  and type of  venous  access ( i.e. , central external venous lines , internalized ports , or peripheral access via venipuncture ) . Participants were 55 pediatric oncology patients , aged 3 - 18 years , who were undergoing routine blood work .  Pain ratings were obtained using the  Faces Pain Scale-Revised  ( FPS-R ) and conversation during the procedure was audio taped for coding using the Child-Adult Medical Procedure Interaction Scale-Revised ( CAMPIS-R ) . Children 's ratings of pain using the FPS-R were similar in the port ( M=2.57/10 , st and ard deviation [SD]=3.46 ) and peripheral ( M=2.56/10 , SD=3.24 ) groups , despite the fact that most children with internal ports were given a topical anesthetic . Similarly , there were no differences between port and peripheral groups in rates of child coping or distress , or parent and nurse observations of child pain . As would be expected , external line access was not associated with pain or distress , even among very young children , suggesting that they appropriately understood the pain rating scale . Results of the transcribed CAMPIS-R data indicate that the influences in adult-child interaction are bidirectional . Support was found for the well-established positive relationship between child distress and adult reassurance and empathy . Implication s for intervention and selection of central venous access devices are discussed
