The UCLA Trauma Checklist is an important tool for helping to identify and assess the depth of psychological trauma experienced by individuals. Developed at the University of California, Los Angeles (UCLA), it has become one of the most widely-used and reliable assessment tools for evaluating post-traumatic stress disorder (PTSD) symptoms in both adults and children. The UCLA Trauma Checklist allows clinicians to accurately gauge a patient’s level of distress related to their traumatic experiences and provides an essential guide for treatment planning.
