The Reiss Screen for Maladaptive Behavior, an instrument used to ident
ify mentally retarded persons with mental health problems, was evaluat
ed with 89 mentally retarded adults. Reliability and validity of the R
eiss Screen, as well as the relationship with subject characteristics,
is reported for a Dutch population. Internal consistency on the total
score was good and modest on most subscales. The subscale autism had
inadequate internal consistency. Interrater reliability was low to mod
est. Further, the Reiss Screen had good criterion validity. Last, few
relationships were found between Reiss Screen scores and subject chara
cteristics.
