title: Developing a responsive measure of change for paediatric brain injury inpatient rehabilitation.
abstract: OBJECTIVE
  To describe conceptual and methodological issues to be addressed in developing a responsive clinical performance measure for paediatric brain injury inpatient rehabilitation. Selected statistical approaches used to examine responsiveness of two functional activity scales (daily and social behavioural activity) of a prototype measure are presented to illustrate these issues.
  
  
  METHODS
  Retrospective chart review.
  
  
  METHODS
  Data on 65 children, aged 6 months to 18 years (X = 9.5 years) were collected during 1998 and 1999 from eight sites in the USA. Responsiveness was examined using effect sizes and a number of parametric and non-parametric tests.
  
  
  RESULTS
  Significant improvements from admission to discharge were found on all item and scale scores (p < 0.001). Moderate significant relationships were found between activity scale change scores and external ratings of change.
  
  
  CONCLUSIONS
  Findings provide evidence that the activity scales have the potential to be responsive and point to issues that will need to be addressed in future measurement development.
