Responding to Correspondence on “Clinical Outcome Assessment Instruments in Schizophrenia: A Scoping Literature Review with a Focus on the Potential of Patient-reported Outcomes”

Dear Editor:

We thank the author of the letter to the editor for their interest in our article “Clinical Outcome Assessment Instruments in Schizophrenia: A Scoping Literature Review with a Focus on the Potential of Patient-reported Outcomes.”¹

Please note that instrument types were categorized by who completes them—patient versus observer/clinician. In addition, symptoms include many different facets of schizophrenia, and cognitive impairment associated with schizophrenia can be considered a symptom. Others may wish to explore outcome instruments using different categorizations. The purpose of our work was not to describe each instrument and its scoring in granular detail, but to identify the instruments, assess who they were designed to be completed by, provide high-level psychometric and scoring details, and note whether they had minimal clinically important difference (MCID) values associated with them.

We look forward to further contributions to the literature regarding clinically relevant and actionable outcomes so that we can continue improving the state of the art in the development of interventions for people with schizophrenia.

With regards,
