To evaluate the properties of the Pain Catastrophizing Scale (PCS) from a Rasch paradigm. ⋯ The results of this secondary analysis suggest that the PCS can be appropriately evaluated as an interval-level scale when the composite 13-item score is considered, as has been standard practice to date.

Associations between 4 forms of pain (ie, arthritis, severe/frequent headaches, chronic spinal pain, and other chronic pain) and borderline personality disorder (BPD) symptoms were investigated in the general population. ⋯ This is the first study to demonstrate that BPD symptoms are positively associated with chronic spinal pain, severe/frequent headaches, and other chronic pain conditions in a sample representative of the general population. The findings also suggest that relationships between remitted pain conditions and BPD symptoms warrant additional study.
