What are the three strengths of using the international classification for mental illness?

The International Classification of Diseases (ICD) provides a standardized framework for diagnosing mental illnesses, which enhances consistency and reliability in clinical practice across different regions. It facilitates effective communication among healthcare professionals by using a common language for mental health conditions. Additionally, the ICD supports research and public health initiatives by enabling the systematic collection of data on mental health disorders, helping to inform policy and resource allocation.
