Pre = pretreatment (i.e. at randomization); Post = post‐CT‐PTSD/WL (Week 11); 6MFU = 6‐month follow‐up; 12MFU = 12‐month follow‐up; CPSS, Child PTSD Symptom Scale; CT‐PTSD, Cognitive Therapy for PTSD; SDQ, Strengths and Difficulties Questionnaire; WL, waiting list.
a
Within‐group; negative scores indicate worsening symptomatology/functioning.
b
Between‐group; positive scores indicate superiority of CT‐PTSD.
