Correction
The article entitled "Substance Use Among Patients With a Psychotic Disorder in a Psychiatric Emergency Room" by Cynthia A. Claassen, Ph.D., Saundra Gilfillan, D.O., Paul Orsulak, Ph.D., and associates in the March 1997 issue (pages 353-358) contained errors in Table 1. Under the "positive results" heading, patients exhibiting no suicidality should have numbered 18, or 25 percent. Under the "negative results" heading, patients exhibiting no suicidality should have numbered 69, or 78 percent. In addition, the substance propoxyphene used by one patient was mislabeled as propranolol in text on page 357. The authors regret the errors.
