if you google “complex ptsd test” a good number of such tests will come up.

Here is a website on the condition that I have found very helpful: https://www.pete-walker.com/

There are also many YouTube videos on the subject.

Complex PTSD was first described in a book by Harvard psychologist Judith Herman called Trauma and Recovery. She defines CPTSD as a condition that occurs due to repeated periodic trauma, as opposed to a single instance of trauma that can instigate PTSD.
