- Clinical Psychology Evidence-Schizophrenia
- Classification systems
- DSM
- Kim-Cohen: good validity in the DSM if multiple data sources were used
- Goldstein: found inter-rater reliability in the DSM for patients with schizophrenia
- Brown et al: overall reliability in DSM but some issues with boundaries
- The use questionnaires and interviews used to study the validity and reliability of the DSM can lack validity
- ICD
- Jakobson et al: concluded ICD gave a reliable diagnosis of schizophrenia, as it showed good agreement with a second diagnosis using a different tool
- Pihlajamaa et al: found that generally when the ICD is used the diagnosis matches a diagnosis given by a different system
- Hiller: compared the ICD with the DSM and found the ICD gave a higher level of reliability
