We conducted an investigation to determine if a subset items from the PCL-5 could perform similarly to that of the full scale PCL-5. We found evidence for a 4- and 8-item version of the PCL. A copy of the measure can be downloaded below. A formula to convert a score on the 8-item version to that of the total scale is also included.
Abbreviated PCL Forms
Zoe Brier developed a formula to take a score on the PCL-5 8-item version and convert it to a comparable score on the PCL-5 total score (Brier et al., in press). The formula is as follows:
Total Score on PCL-5 = 2.15*B1 + 1.78*B4 + 1.79*C1 + 1.35*C2 + 3.03*D2 + 2.96*D5 + 2.88*E4 + 2.53*E5
The above formula will give you a score that is within 3-4 points of the total PCL-5 score.
Calculator function is coming soon!
