Disability terminology: the use of "disability," "disorder," and "illness" in academic writing

The ways in which words are used to describe and discuss people with disabilities has long been an area of social concern. Previous research has demonstrated that language can overtly and subtly influence cognitions and perceptions of individuals, but there is less research on how language relates to perceptions of individuals with disabilities.

A content analysis of 236 peer-reviewed articles was performed to explore differences in the frequency of the use of "disability," "disorder," and "illness" in academic articles related to eight common conditions: deafness, blindness, multiple sclerosis, quadriplegia, anxiety, depression, schizophrenia, and addiction.

Results indicated that there were differences in how disability language was used by academic writers. Specifically, "disability" appeared in the writing more frequently in articles related to physical disabilities, "disorder" appeared most frequently in articles related to anxiety and depression, and "illness" appeared most frequently in articles related to schizophrenia.

This observed difference in frequency use could reflect differences in the context and meaning of the use of these conditions. Suggestions for future research are discussed.
