Prominent disability rights groups have adopted positions opposing the legalization of assisted suicide. That physicians and other health professionals would assist in suicides of persons with incurable conditions while offering suicide prevention to "healthy" individuals is, they maintain, evidence of social discrimination and an unwarranted devaluation of the quality of life of people with disabilities. This article examines empirical literature relevant to the question, Is there evidence that disability affects life in a manner that justifies an exception to the general practice of preventing rather than endorsing suicide? Research findings are discussed in terms of their bearing on the disability rights opposition to physician-assisted suicide and the need for research addressing the dynamics of death requests of persons with disabilities.The Oregon Death with Dignity Act (1994) and various proposed statutes and referenda for legalizing assisted suicide give physicians primary authority to judge whether individuals who request suicide assistance qualify to receive it. The competence of health professionals as gatekeepers of assisted suicide and the professional propriety of that arrangement have been challenged in literature addressing physician fallibility in detecting treatable depression (Misbin, 1991;Muskin, 1998), the potential corruption of the physician's role as healer and the possible erosion of physician-patient trust (Gaylin, Kaas, Pellegrino, & Siegler, 1988), the conflict between managed care pressures and critically ill patients' needs for costly care (Russell, 1998;W.

Although some prominent individuals with disabilities have lobbied in favor of legalizing assisted suicide, most major disability rights organizations in the
