COSMIN psychometric property boxes: A =  internal consistency, B =  reliability, C =  measurement error, D =  content validity, E =  structural validity, F =  hypotheses testing, G =  cross-cultural validity, H =  criterion validity, I =  responsiveness. 4-point scale rating: +++ =  excellent, ++ =  good, + =  fair, 0 =  poor, empty space  =  COSMIN rating not applicable. For exact information regarding the definitions of psychometric properties and 4-point scale rating see COSMIN website (www.cosmin.nl). ^a  =  Test-Retest-Reliability, ^b  =  Inter-rater-Reliability, ^c  =  Intra-rater-Reliability, ^d  =  only evaluation of the quality of the translation procedure, ^p  =  patient version, ^ph  =  physician version.
