The inter-rater reliability of Hall and Baker's REHAB scale: a cross-validation study.

The impending closure of many large psychiatric hospitals has led to the involvement of clinical psychologists in surveys of whole hospital populations. REHAB is a recent addition to the range of behaviour-rating scales. In a test of the inter-rater reliability of this scale, we have assessed the ratings from an initial sample of 50 patients. We obtained higher correlation co-efficients than expected given the larger number of raters used in our study. Some implications for the general use of rating scales in reprovision are discussed.
