Although the significance of poor physical health for suicide risk is well established, the potential relevance of physical disability, as distinct from diseases and traumas that give rise to disability, has received little attention. Prior evidence suggests the possible utility of the stress process theoretical model for understanding variations in risk for suicide ideation and the contribution of physical disability to such risk. In this article, we examine the independent and joint explanatory significance of physical disability and components of the stress process model for risk of suicide ideation. Data from an ethnically diverse and representative sample of disabled and nondisabled adults (n = 1,768) reveal that physical disability is associated with a greater risk of lifetime suicidal ideation.
