September 26, 2019

Purpose: Examine the psychometric properties of the World Health Organization Disability Assessment Schedule 2.0 among U.S. Iraq/Afghanistan Veterans with a combination of mild traumatic brain injury and behavioral health conditions using Rasch analysis.

Methods: 307 Veterans were classified as either combat control (n = 141), or one of three clinical groups: mild traumatic brain injury (n = 10), behavioral health conditions (n = 24), or both (n = 128). Data from the three clinical groups were used to establish step and item calibrations serving as anchors when including the control group.
