The range of scores for the PCL-5 is 0-80. The United States National Centre for PTSD (NC-PTSD) states that "a cut-point score of 31-33 appears to be reasonable based upon current psychometric work" and that "the patient may benefit from PTSD treatment." To assist clinicians in making a diagnosis of PTSD using the DSM-5 criteria, the NC-PTSD recommends a score of 2 "moderately" or above as an endorsement of a symptom, in which case DSM-5 would require at least: one Criterion B item (questions 1-5), one Criterion C item (questions 6-7), two Criterion D items (questions 8-14), and two Criterion E items (questions 15-20). They caution however that, in general, using a cutoff score tends to produce more reliable results than the DSM-5 diagnostic rule.
It should be noted that the above version of the questionnaire is intended for weekly monitoring of symptoms and does not include the DSM-5 Criterion A. It therefore cannot be used as a diagnostic tool.

Please treat your scores on these or any other online questionnaires with caution. Questionnaires cannot be used to make a diagnosis of a mental health condition. Where a mental health condition has been diagnosed by a suitably qualified and experienced health professional these questionnaires may be used as a guide to the current severity of your condition. Always consult with a qualified health professional if you are concerned in any way about your mental health.
If you are worried about your safety, you should immediately consult with your GP or another suitably qualified health professional. If you are in the UK the following numbers might be of help to you:
