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 .
Do cartoon stickers given after a hemoglobin finger stick influence preschoolers' pain perception?
The purpose of this study was to determine if providing a sticker after a finger stick for hemoglobin check reduced pain perception among preschool-aged children . The hypothesis was : Sticker rewards influence the perception of pain as measured by the Oucher scale following a finger stick to check hemoglobin . Preschoolers from Headstart Centers in a southeastern city were recruited for the study . The age range of participants was between 3 and 5 years . The children were assigned r and omly into two groups : those receiving stickers ( Group I ) , and those not receiving a sticker ( Group II ) . Subsequently , each participant 's pain level was assessed using the Oucher scale within 1 minute of the finger stick . There was no statistically significant difference in pain scale ratings between the two groups when comparing whether or not a cartoon sticker was given t ( -.937 , df 128 , P = .351 ; 95 % confidence interval ) . This study was clinical ly significant in that nonpharmacological interventions were utilized in an attempt to reduce pain in young children . Future research should determine whether receiving rewards ( such as a cartoon sticker , adhesive b and ages , or small toys ) alone or in conjunction with distraction measures are efficacious in pain reduction in younger children
