PTSD Checklist

The PTSD Checklist (PCL) is a widely used self-report questionnaire designed to assess symptoms of post-traumatic stress disorder (PTSD). It evaluates key symptoms such as intrusive thoughts, avoidance behaviors, negative alterations in mood and cognition, and hyperarousal. Respondents rate the frequency and severity of each symptom over a defined period, typically the past month, using a Likert scale. The PCL is utilized in clinical practice, research, and screening programs to identify individuals experiencing PTSD symptoms and to monitor treatment progress. Different versions of the PCL exist, including those tailored for specific populations such as military veterans or civilians.
