A 9-year-old girl who disclosed sexual abuse by a family member six months ago is being treated with Trauma-Focused Cognitive Behavioral Therapy (TF-CBT). She has completed psychoeducation, relaxation skills, and affective modulation components. Her therapist now introduces a gradual process in which the child is asked to tell the story of what happened, starting with less distressing details and progressively incorporating sensory memories, thoughts, and feelings associated with the worst moments. The narrative is shared with the non-offending caregiver in a conjoint session. Which TF-CBT component is being implemented, and which element distinguishes TF-CBT from standard play therapy approaches?
