Need for Stability and Predictability in Terminology in Times of Change and Challenges

Area of Science:

• Disability Studies
• Medical Terminology
• Public Health Policy

Background:

• Terminology confusion in intellectual and developmental disabilities (IDD) hinders clear communication and accurate diagnosis.
• Inconsistent use of terms like 'disability' and 'disorder' complicates research and clinical practice.
• Lack of standardized definitions for intellectual disability (ID) and developmental disability (DD) creates ambiguity.

Purpose of the Study:

• To provide actionable solutions for reducing terminology-related confusion in the field of IDD.
• To promote consistent and accurate use of diagnostic terms.
• To enhance clarity in scientific literature, policy documents, and clinical settings.

Main Methods:

• Analysis of current diagnostic manuals (e.g., DSM, ICD).
• Review of public laws and federal administrative regulations pertaining to disability.
• Synthesis of relevant peer-reviewed literature on IDD terminology.

Main Results:

• Distinguishing between a disability and a disorder is crucial.
• Adhering to consensus definitions for intellectual disability and developmental disability is recommended.
• Avoiding the combination of ID and DD into a single diagnostic term is advised.
• Using specific initials for each condition improves clarity.

Conclusions:

• Implementing standardized terminology is essential for advancing the field of IDD.
• Clear definitions and distinctions reduce confusion among professionals and the public.
• Consistent terminology supports better research, policy development, and patient care.
