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 .
Parents’ Positioning and Distracting Children During Venipuncture
The purpose of this study was to determine the effectiveness of parental positioning and distraction on the pain , fear , and distress of pediatric patients undergoing venipuncture . An experimental-comparison group design was used to evaluate 43 patients ( 20 experimental and 23 comparison ) who were 4 to 11 years old . Experimental participants used parental positioning and distraction . All participants rated their pain and fear ; parents and child life specialists ( CLS ) rated the child ’s fear , and CLS rated the child ’s distress . Self-reported pain and fear were highly correlated ( p < .001 ) but not significantly different between the two groups . Fear rated by CLS ( p < .001 ) and parents ( p = .003 ) was significantly lower in experimental participants . Although no difference was found in distress between the two groups , a significant time trend was discovered ( p < .001 ) . The parental positioning-distraction intervention has the potential to enhance positive clinical outcomes with a primary benefit of decreased fear . Further research is warranted
