The CAST*MR is a standardized instrument for forensic
evaluators to assess the competence of persons with mental
retardation to stand trial. Based on criteria in the case of Dusky
vs United States, the CAST*MR has seperate sections for Basic
Legal Concepts, Skills to Assist Defense, and Understanding of Case
Events. The examiner reads each question aloud and records the
client's response in a booklet. There is a reusable Subject Form that
allows the client to follow along as the examiner reads the question.
Reliability estimated at .92 (internal); .90 test-retest. Interscorer
reliability in Part III estimated at 80% and at 90%. A panel of
expert criminal disability lawyers rated the items and the format
favorably. The CAST*MR was favorably reviewed by Deborah K. Cooper,
Ph.D. and Thomas Grisso, Ph.D. in Behavioral Sciences and the Law, 15,
347-364 (1997). The instrument has been used in many forensic assessments.
