The PCL-5 can be scored in different ways:
•A total symptom severity score (range - 0-80) can be obtained by summing the scores for each of the 20 items.
•DSM-5 symptom cluster severity scores can be obtained by summing the scores for the items within a given cluster,
i.e., cluster B (items 1-5), cluster C (items 6-7), cluster D (items 8-14), and cluster E (items 15-20).
•A provisional PTSD diagnosis can be made by treating each item rated as 2 = "Moderately" or higher as a symptom endorsed,
then following the DSM-5 diagnostic rule which requires at least:
1 B item (questions 1-5), 1 C item (questions 6-7), 2 D items (questions 8-14), 2 E items (questions 15-20).
•Preliminary validation work is sufficient to make initial cut-point suggestions, but this information may be subject to change.
Overall, optimal PCL-5 cut-points appear to be 11-14 points lower than PCL for DSM-IV cut-points,
with closer to an 11-point difference for more stringent cutoffs and closer to a 14-point difference for more lenient cutoffs.
A PCL-5 cut-point of 38 appears to be a reasonable value to propose until further psychometric work is available.
