Corrections
In the article “Early Expression of Negative/Disorganized Symptoms Predicting Psychotic Experiences and Subsequent Clinical Psychosis: A 10-Year Study” by Maria-de-Gracia Dominguez, M.D., et al. (published online July 15, 2010; doi: 10.1176/appi.ajp.2010.09060883), the middle name of the second author, Meram Can Saka, M.D., was lowercased, which could lead to indexes mistakenly including it as part of the surname. This has been corrected for the article's print appearance in the September 2010 issue and for its online posting as part of that issue, replacing the article posted July 15. The correct citation for the article is as follows:
Dominguez MDG, Saka MC, Lieb R, Wittchen H-U, van Os J: Early expression of negative/disorganized symptoms predicting psychotic experiences and subsequent clinical psychosis: a 10-year study. Am J Psychiatry 2010; 167:1075–1082
