Rasch Analyses of the Wheelchair Use Confidence Scale

The WheelCon is composed of 2 dimensions. The recoded measurements using a 0-to-10 response scale from the 13-item mobility and 8-item self-management efficacy subscales have good reliability, as do the measurements from the 21-item WheelCon Short Form. The use of the subscales, the short form, or both, depends on the context in which they are being considered. Research to establish the reliability and validity of the measurements using the 0-to-10 response format is warranted.
