While trauma-focused CBT is already used to help treat the disorder in adults, children who experience multiple traumas are often considered harder to treat. Half of these participants received the standard treatment currently offered at mental health services, while the others received trauma-focused CBT. The researchers observed that immediately after therapy, trauma-focused CBT was not dramatically better than the typical treatment. However, after 11 months of therapy, participants who received trauma-focused therapy showed significantly greater improvements in not just PTSD symptoms but also depression, anxiety and regulating emotions. The results give the researchers hope that a wider scale trauma-focused CBT treatment service could operate effectively in community settings.
