title: The DISABKIDS generic quality of life instrument showed cross-cultural validity.
abstract: OBJECTIVE
  The aim was to test the performance of a cross-culturally developed disease-generic quality of life (QoL) measure for children with chronic diseases in a multinational clinical study.
  
  
  METHODS
  The study was conducted in pediatric hospitals across seven European countries in a sample of 1,153 children with seven chronic conditions, aged 8-16. The design included test and retest on child, parent, and clinical measures concerning health status, functioning, and quality of life.
  
  
  RESULTS
  The condition-generic QoL measure showed satisfactory item and scale performance, as well as structural validity across the seven countries. There was a high agreement between the child and proxy assessment across the different countries in all subscales of the condition-generic instrument, except for socioemotional dimensions in some countries. Gender, age, and severity-adjusted covariance analyses showed significant country differences in QoL. The discriminative potential of the condition-generic measure to distinguish between clinical characteristics was higher than that of a generic measures.
  
  
  CONCLUSIONS
  The psychometric performance of both items and scales of the DISABKIDS condition oriented measure was good across cultures, despite a range of cross-cultural differences. The condition-generic measure performs better in discriminating with respect to clinical characteristics than the generic measures; however, results need replication in representative studies.
