|---|---|---|---|---|---|---|---|---|
| 1. Age | 0.07 | 0.16* | ||||||
| 2. Gender | 0.11 | 0.12 | 0.02 | |||||

| 7. Number of pain sites | 0.09 | 0.37** | -0.05 | 0.09 | 0.20** | -0.08 | -0.11 | 0.08 |
Point-biserial correlations were calculated for all correlations involving the dichotomous variables ethnicity, gender, and education; all others are Pearson product moment correlations. Pain severity=pain severity subscale of the Multidimensional Pain Inventory. CAPS total=total score on the Clinician Administered PTSD Scale.
