TF-CBT is an evidence-based treatment to address youth (ages 3-18 years) posttraumatic stress disorder (PTSD) and related difficulties. It is a components- and phase- based treatment that therapists provide individually and in parallel to youth and their parents or primary caregivers, with additional conjoint child-parent sessions. TF-CBT has been tested in 25 randomized controlled trials and many additional effectiveness studies around the world, with strong evidence of improving children’s PTSD and related difficulties in 8-25 sessions, for children of different genders, races, ethnicities, and who have experienced diverse types of traumas.
