Rasch calibration of the 25-item Connor-Davidson Resilience Scale.

Rasch modeling was used to examine the 25-item Connor-Davidson Resilience Scale within adults ( = 410) in a weight management program. Rasch analysis assessed model-data fit, item difficulty and person's resilience level, an item-person map to evaluate relative distribution items and persons, and rating scale function. Four misfit items were identified and removed.
