Translation, cross-cultural adaptation, and measurement properties of the Nepali version of the central sensitization inventory (CSI)

Table 2 Results of hypotheses testing for construct validity of the CSI-NP (N = 100)

Scale	Construct validity (correlation with baseline scores)
Scale	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%)
