London CHANT validation study: Reliability (inter-investigator), internal consistency, and item-total correlations.

Spearman’s Rho showed strong positive correlation for inter-tester reliability among all four components of the CHANT. Internal consistency of CHANT was assessed using Cronbach’s α coefficient—and this revealed a strong consistency of 0.88 among its four different dichotomous components indicating that the multi-item CHANT scale measures the same concept, i.e. peripheral neuropathy.
