I am only familiar with the interactionist model as articulated by Scott. One difference appears to be that the Social Model carves out the category of “disability” to specifically refer to morally wrong ways that society restricts, discriminated against, or omits to accommodate impaired people. It has a moral stance built in. The Interactionist model uses “disability” as a synonym for impairment and doesn’t seem to have an intrinsic moral stance—it just makes a neutral statement that what people can or can’t do has to do with both environment and physical impairment.
