title: [Screening for Anxiety in Cardiovascular Rehabilitation Patients: Concurrent Validity and Cut-off Values of the ACAT-cardio].
abstract: OBJECTIVE
  The computer adaptive test ACAT-cardio has been developed in order to screen cardiovascular rehabilitation patients for anxiety. This study aims at investigating the criterion validity, and identifying appropriate cut-off values for its use in cardiac rehabilitation.
  
  
  METHODS
  106 cardiovascular rehabilitation patients were tested for anxiety disorders using the instruments ACAT-cardio and SKID-I. Receiver operating characteristics were employed to analyse the results of 3 stopping rules of the ACAT-cardio.
  
  
  RESULTS
  ROC analyses for the stopping rules yielded areas under the curve (AUC) between 0.80 and 0.84. The ideal cut-off values of the ACAT-cardio (theta scores) were - 0.20 (sensitivity: 86%),-0.23 (sensitivity: 71%) and - 0.35 (sensitivity: 86%).
  
  
  CONCLUSIONS
  The ACAT-cardio has proven to be a valid instrument that can be used for screening anxiety disorders in cardiac rehabilitation.
