title: [Measuring change in rehabilitative cardiology: reliability of a short questionnaire to assess an outcome].
abstract: The present Italian health planning demands the use of tools, care and treatments useful for the National Health Service, but with empirical effectiveness scientifically sustained. Aim of the present paper is to verify the validity, the reliability and the responsiveness of the factor "Perception of positive change" (named Schedule C) in cardiovascular rehabilitation.
  
  
  METHODS
  The reliability of the Schedule C of the CBA VE has been examined comparing the mean scores obtained from each item at the entry and just before the discharge through the t-Student for paired sample. To assess the concurrent validity we used the AD Short Scale to measure anxiety and depression. 100 patients who underwent cardiac surgery were enrolled during hospitalization for a Cardiac Rehabilitation Programme. Cronbach's alpha was used to assess internal consistency of each item.
  
  
  RESULTS
  Each item of the Schedule C demonstrated good internal consistency (Cronbach Alpha > .88) and elevated correlations item-total for each item. The strong correlation of anxiety and depression scores with the Schedule C points out appropriate concurrent validation.
  
  
  CONCLUSIONS
  We believe that the Schedule C of the CBA VE is endowed with suitable metric validity and then useful as outcome evaluation in cardiovascular rehabilitation settings.
