Part A (Q4): Write a note on ICD-10 Classification.

The ICD-10 (International Statistical Classification of Diseases and Related Health Problems, 10th Revision) is a medical classification list created by the World Health Organization (WHO).

In the context of psychology and social work, Chapter V (Block F) of the ICD-10 is the most critical, as it deals specifically with Mental and Behavioral Disorders.

Key features include:

1. Global Standard: It is the standard diagnostic tool for epidemiology, health management, and clinical purposes worldwide (unlike the DSM-5, which is primarily used in the USA).
2. Coding System: It uses an alphanumeric coding system (e.g., F32 is the code for Depressive episode, F20 for Schizophrenia). This allows health professionals globally to record diagnoses consistently.
3. Categories: It classifies mental disorders into broad categories, including organic mental disorders, disorders due to psychoactive substance use, schizophrenia, mood disorders, neurotic/stress-related disorders, and disorders of adult personality and behavior.
4. Utility for Social Workers: Social workers use ICD-10 codes to understand clinical diagnoses, communicate with psychiatrists, and ensure clients are eligible for specific state-sponsored welfare programs or insurance claims related to mental disability.
