Problem: For a client to be diagnosed with PTSD based on DSM-5 criteria, they should meet the following one or more intrusion signs, an encounter with the traumatic event, one or more signs of avoidance. One of such tools used for PTSD diagnosis is the PCL-5 (Bryant, 2019). PCL-5 is a self-report measuring tool comprising 20 questions that evaluates the 20 DSM-5 PTSD symptoms. PCL-5 primary functions include PTSD diagnosis, screening clients for PTSD, and monitoring the disorder's symptom alterations during or after treatment (Bryant, 2019). Another powerful tool used for PTSD diagnosis is the semi-structured or structured interviews like the Clinician-Administered PTSD Scale (CAPS). The tool is a 30-item semi-structured or structured interview that can be utilized to make PTSD diagnoses and evaluate PTSD symptoms. Need Assignment Help?
