Based on available evidence , the NRS-11 , FPS-R , and CAS were strongly recommended for self-report of acute pain .
Only weak recommendations could be made for self-report measures for postoperative and chronic pain .
No measures were recommended for children younger than 6 years , identifying a need for further measurement refinement in this age range .
Abstract In 2006 , PAIN published a systematic review of the measurement properties of self-report pain intensity measures  in children and adolescents ( Stinson JN , Kavanagh T , Yamada J , Gill N , Stevens B. Systematic review of the psychometric properties , interpretability and feasibility of self-report pain intensity measures for use in clinical trials in children and adolescents .
Key developments in pediatric pain necessitate an up date of this work , most notably growing use of the 11-point numeric rating scale ( NRS-11 ) .
Our aim was to review the measurement properties of single-item self-report pain intensity measures in children 3 to 18 years old .
A secondary aim was to develop evidence -based recommendations for measurement of child and adolescent self-report of acute , postoperative , and chronic pain .
Inter-rater agreement and reliability of the COSMIN (COnsensus-based Standards for the selection of health status Measurement Instruments) Checklist
Background The COSMIN checklist is a tool for evaluating the method ological quality of studies on measurement properties of health-related patient-reported outcomes . The aim of this study is to determine the inter-rater agreement and reliability of each item score of the COSMIN checklist ( n = 114 ) . Methods 75 articles evaluating measurement properties were r and omly selected from the bibliographic data base compiled by the Patient-Reported Outcome Measurement Group , Oxford , UK . Raters were asked to assess the method ological quality of three articles , using the COSMIN checklist . In a one-way design , percentage agreement and intraclass kappa coefficients or quadratic-weighted kappa coefficients were calculated for each item . Results 88 raters participated . Of the 75 selected articles , 26 articles were rated by four to six participants , and 49 by two or three participants . Overall , percentage agreement was appropriate ( 68 % was above 80 % agreement ) , and the kappa coefficients for the COSMIN items were low ( 61 % was below 0.40 , 6 % was above 0.75 ) . Reasons for low inter-rater agreement were need for subjective judgement , and accustom to different st and ards , terminology and definitions . Conclusions Results indicated that raters often choose the same response option , but that it is difficult on item level to distinguish between articles . When using the COSMIN checklist in a systematic review , we recommend getting some training and experience , completing it by two independent raters , and reaching consensus on one final rating . Instructions for using the checklist are improved
