Abstract
The shift from a multiaxial system of diagnosis in the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5) brought forth the discontinuation of the Global Assessment of Functioning (GAF). DSM-5 proposes the use of a more reliable method for assessing and describing disability, the World Health Organization Disability Assessment Schedule 2.0 (WHODAS 2.0). The WHODAS 2.0 is widely-used within the Department of Veterans Affairs (VA) and the Veterans Benefits Administration to guide clinical decision making and assist in decisions pertaining to financial compensation. While the WHODAS 2.0 purports to be well-validated for adults cross-culturally in clinical and non-clinical samples, research is limited pertaining to the factor structure of the WHODAS 2.0 in non-compensation seeking U.S. Veteran populations. This study evaluated the factor structure of the WHODAS 2.0 in a sample of 464 Veterans receiving VA mental healthcare. Exploratory and confirmatory factor analyses of the WHODAS 2.0 data were conducted. Analyses confirmed the hardiness of the WHODAS 2.0 for use with Veterans. However, exploratory analyses pointed to several items that may reduce the functioning of the questionnaire in clinical Veteran samples. Exploratory and confirmatory analyses indicated better model fit can be achieved.
