Table 3. Pearson’s correlations between the connectivity strength of the ROIs and pain catastrophizing in each group.
| PCS-total | Rumination | Magnification | Helplessness | Amygdala L- NAc R | |
|---|---|---|---|---|---|
| HSP (n = 24) | r (p) | r (p) | r (p) | r (p) | r (p) |
| Amygdala L- NAc R | 0.09 (0.70) | 0.14 (0.50) | -0.11 (0.60) | 0.15 (0.50) | - |
| Amygdala L-Amygdala R | 0.52 (0.009) | 0.41 (0.04) | 0.37 (0.07) | 0.60 (0.003) | 0.50 (0.01) |
| LSP (n = 24) | r (p) | r (p) | r (p) | r (p) | r (p) |
| Amygdala L- NAc R | 0.18 (0.40) | 0.12 (0.60) | -0.00 (0.90) | 0.28 (0.20) | - |
| Amygdala L-Amygdala R | 0.11(0.60) | 0.05 (0.80) | 0.03 (0.90) | 0.17 (0.40) | 0.50 (0.01) |
Note, HSP = high sensitivity to pain; LSP = low sensitivity to pain; PCS = Pain Catastrophizing Scale; L = left; R = right. Bold–statistically significant after Bonferroni corrections for multiple comparison, p<0.0031.
