Thirty-one participants did not endorse prior trauma and thus did not respond to PCL-C items.

Correlations between PTSD symptom clusters (i.e., PTSD re-experiencing, avoidance, and arousal) and other variables thus represent a sample size of n = 170. CPCI = Chronic Pain Coping Inventory; MPI = Multidimensional Pain Inventory.
