Description
The CRS as originally published in 1981 contained 52 items; an expanded version was developed in 1998. The latter includes 61 items that parallel the DSM-IV diagnostic criteria. This version is copyrighted by Multi-Health Systems Inc (www.mhs.com), who also produce scoring software and diagnostic guides. Because most of the reported validity and reliability evidence refers to the original version of the scale, it will be described here. Interested users can then contact Multi-Health Systems to obtain the revised version.
