Only three multi-item and two single-item instruments were identified as being reliable and valid among pediatric cancer or HSCT patients and would therefore be appropriate to measure anxiety in this population
Purpose The primary objective was to describe anxiety measurement instruments used in children and adolescents with cancer or undergoing hematopoietic stem cell transplantation ( HSCT )  and summarize their content and psychometric properties .
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
