What PCL-5 score indicates probable PTSD?

A total score of 33+ is the recommended provisional PTSD diagnosis cutoff. Symptom cluster criteria require careful review even for lower-scoring individuals.

How does PCL-5 differ from PCL-C?

PCL-5 aligns with DSM-5's 20 symptoms and four clusters. PCL-C (civilian) was based on DSM-IV's 17 symptoms and three clusters, so scores are not directly comparable.
