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.
Design:
A prospective study.
Subjects:
A convenience sample of 31 medical rehabilitation patients.
Main Measures:
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.
