What's in a name?

★ The Verdict

ICD-11 now says 'intellectual disability'—change your forms and words today, but know the label switch can backfire without respectful context.

✓ Read this if BCBAs who write reports, goals, or insurance docs for clients with ID.
✗ Skip if RBTs who only run programs and never touch paperwork.

01Research in Context

01

What this study did

McDowell (2013) gives a short update on the ICD-11 draft. It says the new manual will drop 'mental retardation' and use 'intellectual disability' instead. The paper is a quick read, not a data study.

02

What they found

The finding is simple: the global disease guide will use the new term. No numbers, no trials, just the policy line. The author tells clinicians to start using the new words now.

03

How this fits with other research

Kleinert et al. (2007) set the stage. They argued the same switch six years earlier, so McDowell (2013) is the follow-through. Ford et al. (2013) lands the same year with the same message, making it a direct replication from the federal side. Hamama et al. (2021) later supersedes the brief note by giving full diagnostic details and support levels. Ohan et al. (2015) adds a warning: an RCT shows that simply telling people to say 'intellectual disability' can raise stigma, an angle McDowell (2013) never mentions.

04

Why it matters

You need to update every report, goal sheet, and parent handout today. Swap 'mental retardation' for 'intellectual disability' and you stay in line with ICD-11, insurance forms, and federal rules. Just remember that the word change alone will not cut stigma; pair it with respectful explanation and person-first language.

03Original abstract

The World Health Organization (WHO) is in the process of developing the 11th edition of the International Classification of Diseases (ICD-11). Part of this process includes replacing mental retardation with a more acceptable term to identify the condition. The current international consensus appears to be replacing "mental retardation" with "intellectual disability". This article briefly presents some of the issues involved in changing terminology and the constraints and conventions that are specific to the ICD.
