The National Institutes of Health, in collaboration with Boston University, developed a new tool for assessing individual functional ability with funding from the Social Security Administration (SSA). The tool, called the Work Disability–Functional Assessment Battery (WD-FAB), uses item response theory and computer adaptive testing to quickly interview people and systematically map physical and mental health functioning.

In this paper, we provide background on the WD-FAB and explore two ways it could improve the delivery of services to people with disabilities. First, the instrument could provide SSA with a more complete understanding of an applicant’s self-reported functional abilities and limitations. SSA could use those insights to improve the disability determination process for those applying for disability benefits. Second, the instrument could help federal, state, and local programs identify interventions for people who need return-to-work services.

The WD-FAB offers an opportunity to leverage advances in approaches to integrate functional information into the assessment of work disability using comprehensive, efficient technologies to capture self-reported functioning.
