Educational Interpretation Guide
Scores map the intensity of reported responses to provide a baseline data profile. A total score of 33 or above is associated with elevated intensity profiles in contemporary literature. For a deeper understanding of trauma responses and established academic guidelines, researchers and users should consult comprehensive resources from institutions like the American Psychological Association.
