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 .
Comparison of two pain scales in indian children
Objective . To compare the Faces Pain Scale and Color Analogue Scale among children aged 6–12 years undergoing selected procedures ( Venipuncture , Intravenous cannulation , Intramuscular injection , Lumbar puncture , Bone marrow aspiration )  and to compare the procedural pain in a child as perceived by the child , parents and health care professionals using the above mentioned scales Methods . This was a prospect i ve , descriptive correlational study of children aged 6–12 years , who had undergone selected procedures . Children were assessed for their pain severity using  Faces Pain Scale and Color Analogue Scale .  Parents and health care professionals also independently assessed the child 's pain using the same scales Results . 181 children who fulfilled the eligibility criteria were enrolled in the study . There was a significant positive correlation ( r = > 0.8 ) between both the pain scales . There was fair to moderate positive correlation ( r = 0.29 to 0.58 ) of pain perception of child with parents and health care professionals Conclusions . Faces Pain Scale and Color Analogue Scales seem to be appropriate instruments for measuring pain intensity among Indian children aged 6–12 years undergoing selected
