Description

The PCL-5 is a 20 item self-report measure of the 20 DSM-5 symptoms of Post Traumatic Stress Disorder (PTSD). Included in the scale are four domains consistent with the four criterion of PTSD in DSM-5: – Re-experiencing (criterion B) – Avoidance (criterion C) – Negative alterations in cognition and mood (criterion D) – Hyper-arousal (criterion E) The PCL-5 can be used to monitor symptom change, to screen for PTSD, or to make a provisional PTSD diagnosis.

Validity and Reliability

The PCL-5 is a relatively new scale (released in 2013), therefore only preliminary validation is currently available. Validation research points to the clinical utility of the PCL-5. All four criterion scales demonstrate high internal consistency (Cohen et al., 2015). There was also a high correlation of PTSD prevalence in a student sample (n = 2490) between the symptom severity (1.4% meeting PTSD criteria) and diagnostic classification scoring methods (1.3% meeting PTSD criteria) (Cohen et al., 2015).

Interpretation

Scores consist of a total symptom severity score (from 0 to 80) and scores for four subscales: – Re-experiencing (items 1-5 – max score = 20) – Avoidance (items 6-7 – max score = 8) – Negative alterations in cognition and mood (items 8-14 – max score = 28) – Hyper-arousal (items 15-20 – max score = 24) In addition to a raw score being presented, a “mean score” is also computed, which is the subscale score divided by the number of items. These scores range between 0 to 5, where higher scores represent higher severity. Consistent with the likert scale: 0 = Not at all 1 = A little bit 2 = Moderately 3 = Quite a bit 4 = Extremely A provisional PTSD diagnosis can be made by treating each item rated as 2=”Moderately” or higher as an endorsed symptom, 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). A cut-off raw score is 38 for a provisional diagnosis of PTSD. This cut-off has high sensitivity (.78) and specificity (.98) (Cohen et al., 2015). If the scale is used to track symptoms over time, a minimum 10 point change represents clinically significant change (as based on the PCL for DSM-IV change scores).
