The disability adjudicators do not use GAF scores specifically in their assessment, since the disability criteria are not the same as the DSM.
DDS basis their decision on the extent to which the “Listings” (Disability Evaluation Under Social Security) are met. For mental impairments they are looking for A) the diagnosis and B) the functional impairment. The main focus is on how the person's illness affects their functioning in four areas: Acitvities of Daily Living (ADLs); social; concentration, persistence and pace; and decompensation. DDS needs evidence that the person has marked impairment in at least two of these areas, or moderate impairment in at least three areas. It is more important for them to have clear, detailed descriptions with examples of how someone is functioning.
