Results of hypotheses testing for construct validity of the CSI-NP (N = 100)
| Scale | Construct validity (correlation with baseline scores) | ||
|---|---|---|---|
| Hypothesis | Results | Hypothesis confirmed? | |
| CSI-NP | Positive weak to strong associations with pain intensity | r = 0.25 (P = 0.013) | Yes |
| Positive weak to strong associations with pain catastrophizing | r = 0.50 (P < 0.001) | Yes | |
| Positive weak to moderate associations with duration of pain | r = 0.10 (P = 0.315) | No | |
| Positive weak to moderate associations with total number of types of pain | r = 0.35 (P < 0.001) | Yes | |
| Women would have significantly higher CSI scores than men | Women had significantly higher CSI scores than men [Mean difference = 7.15 (95% CI: 2.11, 12.19); P = 0.005] | Yes | |
| Total hypothesis met | 4 of 5 (80%) | ||
