ICD-11 should not repeat the mistakes made by DSM-5

Area of Science:

• Psychiatry
• Diagnostic Systems
• Mental Health Classification

Background:

• The existence of multiple psychiatric diagnostic systems, such as the International Classification of Diseases, Eleventh Revision (ICD-11) and the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5), leads to confusion in clinical practice and research.
• There is a recognized need for greater harmonization between these major diagnostic frameworks to improve diagnostic reliability and validity.

Discussion:

• The DSM-5 has incorporated several controversial diagnostic proposals lacking robust scientific evidence and thorough risk-benefit assessments.
• These scientifically questionable inclusions in the DSM-5 present potential pitfalls for other diagnostic systems aiming for harmonization.

Key Insights:

• The development of the ICD-11 presents an opportunity to learn from the methodological and scientific shortcomings observed in the DSM-5.
• Prioritizing evidence-based criteria and comprehensive risk-benefit analyses is essential for the ICD-11 to enhance diagnostic consistency without compromising scientific rigor.

Outlook:

• Future revisions of psychiatric diagnostic systems should focus on collaborative efforts to ensure greater alignment based on strong scientific foundations.
• The ICD-11's careful consideration of DSM-5's limitations can pave the way for more reliable and valid mental health classifications globally.
