For comparison purposes, DSM‐IV and DSM‐5 rates are presented (from Meiser‐Stedman et al., 2017). Comorbid depression was indexed as a score ≥ 8 on the Short Mood and Feelings Questionnaire; comorbid anxiety was indexed as a score of ≥ 60 on the Spence Child Anxiety Scale. The number ‘with comorbid depression’ or ‘with comorbid anxiety’ is the number of participants with the given PTSD diagnosis who also had comorbid anxiety or depression. Week 2 ICD‐10 and ICD‐11 PTSD rates ignore the duration requirement for diagnosis. Frequency of 1 and 2 complex features excludes those who met CPTSD criteria.
