The ICD is currently under revision and this study is the first phase of the electronic field trials for ICD-11 for psychotic disorders. The present study compared ICD-10 and ICD-11 with regards to changes made to the diagnostic guidelines and changes amongst specific disorders. Of specific interest was clinicians’ ability to accurately diagnose disorders that can present with overlapping features. We found that both diagnostic systems were accurate in differentiating disorders that have the potential to be easily confused. For some of the diagnostic guidelines that were undergoing substantial changes from ICD-10 to ICD-11, we did find improvements in the proposed guidelines. Subsequent studies will expand on our findings prior to the release of ICD-11. However, based on our initial findings, the proposed changes do appear to be increasing clinical utility of the diagnostic guidelines.
