title: Reliability of the positive and negative affect schedule (PANAS) in medical rehabilitation.
abstract: OBJECTIVE
  To examine the reliability of the Positive and Negative Affect Schedule (PANAS) in patients 90 and 100 days after discharge from inpatient medical rehabilitation.
  
  
  METHODS
  A prospective study.
  
  
  METHODS
  A convenience sample of 31 medical rehabilitation patients.
  
  
  METHODS
  The PANAS.
  
  
  RESULTS
  The average age was 74 years, 80.7% were female and the average length of stay was 13 days. The test-retest intraclass correlation (ICC) values for the positive and negative affect scales (at the 90 and 100 day follow-up assessment) were 0.79 and 0.93, respectively.
  
  
  CONCLUSIONS
  Our results show that the PANAS has excellent reliability among a sample of patients who received inpatient medical rehabilitation.
