Correlations between PCS subscales and pain and impact.
| Group | Rumination | Magnification | Helplessness | Total PCS |
|---|---|---|---|---|
| MPQ (pain) | ||||
| A (< 2 years) | 0.43** | 0.44** | 0.53** | 0.50** |
| B (2-4 years) | 0.27* | 0.40** | 0.47** | 0.42** |
| C (> 4 years) | 0.32** | 0.23** | 0.36** | 0.34** |
| FIQ (impact) | ||||
| A (< 2 years) | 0.76** | 0.63** | 0.68** | 0.73** |
| B (2-4 years) | 0.48** | 0.59** | 0.58** | 0.60** |
| C (> 4 years) | 0.46** | 0.38** | 0.50** | 0.50** |
Group A (n = 46), Group B (n = 59), Group C (n = 223). MPQ = McGill Pain Questionnaire; FIQ = Fibromyalgia Impact Questionnaire; PCS = Pain Catastrophising Scale. * p < 0.05, ** p < 0.01.
