A psychiatric rating scale for schizophrenia in Singapore (Woodbridge Hospital rating scale for schizophrenia)

This scale is constructed to meet the need for an efficient, rapid and economical method of
measuring change in schizophrenic patients during the course of psychotropic medication (drug trial) in a multi-cultural, multi-lingual population of low educational level. Items are included only if (1) they can be elicited objectively, (2) they are important symptoms of schizophrenia and (3) they are frequent maniJestatz'on of the schizophrenic syndrome as recorded in Woodbridge Hospital. It could be used by a single rater but its reliability should be further improved if two raters are involved.
