We welcome the opportunity to address the difference between low-functioning and negative symptoms because this appears to have not been clearly explained in the original article. Between the time we submitted the trial to the grants.gov website and starting the trial, we became more aware of the importance of functioning as emphasized by the recovery movement.1 In keeping with this, we changed the primary outcome variable to functioning rather than symptoms.
