C. Everington et C. Dunn, A 2ND VALIDATION-STUDY OF THE COMPETENCE ASSESSMENT FOR STANDING TRIAL FOR DEFENDANTS WITH MENTAL-RETARDATION (CAST-MR), Criminal justice and behavior, 22(1), 1995, pp. 44-59
This study investigated the reliability and validity of the Competence
Assessment for Standing Trial for Defendants with Mental Retardation
(CAST-MR) with defendants with mental retardation referred for evaluat
ion of competence to stand trial in the state of Ohio. The CAST-MR dem
onstrated strong internal consistency and interrater reliability With
respect to the instrument's validity, the group referred as competent
had significantly higher total scores, significantly higher scores on
each subsection, and significantly higher scores on seven individual t
est items. The results of discriminant function analyses further suppo
rted the CAST-MR's validity. These findings are discussed in relation
to a previous CAST-MR validation study with a similar population.
