The Sheehan Disability Scale (SDS) is a short, simple, and cost-effective measure of disability and functional impairment that can be quickly administered and scored without disrupting the flow of routine care. The SDS is a composite of three self-rated items designed to measure the extent to which three major domains in the patient’s life are functionally impaired by psychiatric or medical symptoms. The SDS assesses functional impairment in three major life domains: work, social life/leisure activities, and family life/home responsibilities. To improve sensitivity the SDS uses a discretized analog (Discan) scaling metric to simultaneously anchor the impairment spatio-visually, numerically and verbally-descriptively. The Sheehan Disability Scale was developed as a treatment outcome measure that would be sensitive to change and to drug placebo differences over time. Its validity and reliability has been investigated in several studies (references 1, 3, 4, and 5 in How to Cite the SDS below).
