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 .
Pre-surgical child behavior ratings and pain management after two different techniques of tonsil surgery.
OBJECTIVE The purpose of this investigation was to compare child behavior before surgery with experience of pain and anxiety in relation to two techniques of tonsil surgery , to relate previous experiences of surgery/tonsillitis with anxiety and pain , and to compare the children 's , parent 's and nurse 's rating of pain . METHOD Ninety-two children ( 5 - 15 years ) with sleep-disordered breathing ( SDB ) and with or without recurrent tonsillitis were r and omized to partial tonsil resection/tonsillotomy ( TT ) or full tonsillectomy ( TE ) .  MEASURES Parents : Child Behavior Checklist ( CBCL ) . Children : State-Trait-Anxiety Inventory for Children ( STAIC ) and seven-point Faces Pain Scale ( FPS ) . Parents/staff : seven-point Verbal Pain Rating Scale ( VPRS ) . Pain relievers were opoids , paracetamol and diclophenac . RESULTS These children with SDB scored significantly higher on CBCL than did normative groups , but no connection was observed between CBCL rating and experience of pain . There was no relation between pre-operative anxiety and pain . The post-operative anxiety level ( STAIC ) correlated with pain . The TE-group scored higher on STAIC after surgery . Previous experience of surgery or tonsillitis did not influence post-operative pain . The TE-group rated higher experience of pain despite more medication . The nurses scored pain lower than the parents/children and under-medicated . CONCLUSION SDB may influence children 's behavior , but with no relation to post-operative pain . The surgical method predicts pain better than does the child 's behavior rating . The nurses underestimated the pain experienced by the child
