We examined the validity of the Referral Decision Scale (RDS), a test
designed to screen for mental disorder in jail inmates, in a sample of
790 men admitted to an urban pretrial jail. Our results indicated tha
t, in general, the RDS had excellent reliability and acceptable validi
ty as a screening measure for serious mental disorder in jail settings
, despite making a large number of false positive errors relative to b
oth contemporaneous and subsequent assessments of mental disorder. Alt
hough the RDS is well suited for use in research, more information is
needed before the test is used for clinical purposes. We discuss some
potential problems with the use of the RDS in correctional systems.
