Is there any databases on the appropriate language in the service for individuals with disabilities?

You are welcome.

That is new to me, thanks so much.

There has been considerable discussion around people-first and respectful language. Person-first language was a strategic battleground for transforming the ways of thinking about disability (Withers, 2012). Much debate has taken place regarding the appropriate language to use in relation to individuals with disabilities. we should use the more acceptable and appropriate term, “people with intellectual disabilities.” Referring to people with disabilities as “the disabled” or “the mentally retarded” creates an image of a group of people, all of whom have many of the same characteristics. In fact, such labels as “the blind” and “the mentally ill” often do not even include the additional word “people.”
