Randomized Controlled Trial Multicenter Study
Using the WHODAS 2.0 to Assess Functioning Among Veterans Seeking Compensation for Posttraumatic Stress Disorder.
One of the major changes in DSM-5 was removal of the Global Assessment of Functioning (GAF). To determine whether the World Health Organization Disability Assessment Schedule 2.0 (WHODAS 2.0) is a suitable replacement for the GAF, this study compared how well the WHODAS 2.0 and the GAF measured functional impairment and other phenomena related to posttraumatic stress disorder (PTSD) among veterans applying for financial compensation (service connection) for PTSD. ⋯ The WHODAS 2.0 and IPF are acceptable replacements for the GAF and can be used to assess functional impairment among veterans seeking compensation for PTSD.
