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 .
Interactive Music as a Treatment for Pain and Stress in Children During Venipuncture: A Randomized Prospective Study
Objective : The experience of venipuncture is seen by children as one of the most fearful experiences during hospitalization . Children experience anxiety both before and during the procedure . Therefore , any intervention aim ing to prevent or reduce distress should focus on the entire experience of the procedure , including waiting , actual preparation , and conclusion . This study was design ed to determine whether the presence of musicians , who had attended specific training to work in medical setting s , could reduce distress and pain in children undergoing blood tests . Methods : Our sample population was composed of 108 unpremedicated children ( 4–13 years of age ) undergoing blood tests . They were r and omly assigned to a music group ( n = 54 ) , in which the child underwent the procedure while interacting with the musicians in the presence of a parent or to a control group ( n = 54 ) , in which only the parent provided support to the child during the procedure . The distress experienced by the child before , during and after the blood test was assessed with the Amended Form of the Observation Scale of Behavioral Distress , and pain experience with FACES scale ( Wong Baker Scale ) only after the venipuncture . Results : Our results show that distress and pain intensity was significantly lower ( p < .001 ; p < .05 ) in the music group compared with the control group before , during , and after blood sampling . Conclusions : This controlled study demonstrates that songs and music , performed by “ professional ” musicians , have a beneficial effect in reducing distress before , during , and after blood tests . This study shows , moreover , that the presence of musicians has a minor , but yet significant , effect on pain due to needle insertion
