About 25% of individuals exposed to severe trauma will develop PTSD. Significant symptoms include disturbing thoughts and feelings, as well as vivid nightmares related to the traumatic event.

The PCL-5 is based on the American Psychological Association’s diagnostic criteria, and the DSM-5 new version (2013).

The PCL for DSM-IV was revised in accordance with DSM-5 (PCL-5). Numerous important revisions were instated with the PCL-5, including changes to symptom criteria and the addition of new clusters and symptoms of PTSD (so-called subscales). The self-report rating scale for PCL-5 was also improved and recalibrated to reflect improved scientific understanding of PTSD. The improvements to the scale, combined with the increase in psychometric items, means that PCL-5 scores are not compatible with previous PCL measurements such as, for example, for the DSM-IV criteria. In other words, they cannot be used interchangeably.
