After the publication of this article , we became aware of the fact that there was an error in Table Table11 "Measures to be administered at each measurement occasion". This correction contains the revised Table. Specifically, within Table Table11 it should be noted that the Child Trauma Screening Questionnaire (CTSQ) and Clinician Administered PTSD Scale-Child and Adolescent Version (CAPS-CA) are only administered at screening, baseline, post-test, 6-month and 12-month follow-up.
We also note that there was an inconsistency between text in the introduction and methods section. The term PTSD is used in this article to refer to young people experiencing either full PTSD (meeting DSM-IV criteria) or meeting the alternative PTSD-AA algorithm (PTSD-AA) [2,3]. Thus, within the Methods section describing Participants, Recruitment and Inclusion/Exclusion Criteria, it should be clarified that children/adolescents will progress beyond Stage 3 (Diagnostic assessment) if they meet DSM-IV or PTSD-AA criteria for PTSD on the CAPS-CA.
