Errors in Text, Tables, and Figure Legend. In the Article titled “Association Between Posttraumatic Stress and Depressive Symptoms and Functional Outcomes in Adolescents Followed Up Longitudinally After Injury Hospitalization” by Zatzick et al, published in the July issue of the Archives (2008;162:642-648), the University of California, Los Angeles posttraumatic stress disorder (PTSD) Reaction Index (PTSD-RI) scale scores reported as 38 or higher were actually 21 or higher. The error in the original manuscript was due to an inadvertent problem in coding. A PTSD-RI score of 21 or higher is consistent with moderate elevations in PTSD symptom levels that approximate a diagnosis of PTSD during the course of the year after the injury. On page 643 of this article, in the “Methods” section, “PTSD Symptoms” subsection, the second and third sentences of the second paragraph should be replaced with the following: “A PTSD-RI cutoff score of 21 or higher has a sensitivity of 1.0 and a specificity of 0.66 to 0.86 for symptoms consistent with a diagnosis of PTSD, when using the recommended PTSD-RI algorithm criterion of a score of 3 or greater.15 For the algorithm, symptoms consistent with a DSM-IV diagnosis of PTSD are considered present when a score of 3 or greater is reported for at least 1 PTSD intrusive symptom, 3 PTSD avoidant symptoms, and 2 PTSD arousal symptoms.” In addition, throughout the remaining text, in the table headings, and in the legend to Figure 1, any references to a PTSD-RI cutoff of 38 should be replaced with 21.
