Instruments for measuring psychotic disorders

H. Knegtering, R. Bruggeman

summary There are limits to what can be achieved with the instruments for measuring psychotic disorders. However, the diagnosis of psychotic disorders is supported by various semi-structured diagnostic interviews. The severity of the various symptom dimensions can be measured adequately according to several scales. Effective instruments are available for evaluating neurological and somatic side effects and a patient's subjective experience. It is advisable to make regular assessments of symptom severity, unwanted medications effects and the patient's needs.
