ITCT-C is an assessment-driven, multimodal, evidence-based treatment for children ages 5-12, with interview and/or standardized trauma-specific measures administered at 2-3 month intervals to identify particular symptoms and issues requiring focused clinical attention. ITCT-C is based on developmentally appropriate, culturally adapted approaches that can be applied in multiple settings (outpatient clinic, school, hospital, inpatient, forensic, and residential), and involves collaboration with multiple community agencies. ITCT-C has been particularly adapted for economically disadvantaged and culturally diverse children and families.
