Erratum

In the first paragraph of the results section in Rush AJ et al “The 16-item quick inventory of depressive symptomatology (QIDS), clinician rating (QIDS-C), and self-report (QIDS-SR): a psychometric evaluation in patients with chronic major depression” Biological Psychiatry 54:573–583 (this issue), Cronbach’s α for the QIDS-SR16 and IDS-SR16 have been reversed. The sentence should read: “As expected, Cronbach’s α increased consistently over time in this study for all four scales: QIDS-SR16 = .57–.85 (baseline to week 12); IDS-SR30 = .73–.92 (baseline to week 12); . . . .” also, the term “IDS-C30” appears incorrectly twice, as well psychomotor “slowing,” in the second and third sentences of the fourth paragraph within the results section. the sentences should read: “Mood variation (.30) and gastrointestinal complaints (.33) were poorly correlated with the total IDS-SR30 score. Psychomotor agitation (.54), somatic complaints (.44), sympathetic arousal (.45), and panic/phobic symptoms (.47) had moderate correlations with IDS-SR30 total score.” this article was published online on April 10, 2003 at http//:dx.doi.org/10.1016/s0006-3223(03)01866-8.
