What is the primary classification system for mental illness labels?

• A. DSM-5
• B. Classification
• C. Generalized Anxiety Disorder (GAD)
• D. Panic Disorder

Answer: (A)

Mental illness labeling relies on a standardized diagnostic framework. The main system used to classify and name these conditions is the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5). It provides explicit criteria for each disorder, including the specific symptoms, how many are needed, how long they must persist, and the level of impairment required. This standardization helps clinicians communicate clearly, guides treatment planning, and supports consistency in research and insurance coding. While Generalized Anxiety Disorder or Panic Disorder are individual disorders defined within this framework, they are not labeling systems themselves. A term like classification is too broad to serve as the primary system for mental illness labels. The DSM-5 is the go-to reference in many clinical settings, with the International Classification of Diseases (ICD) used globally for coding and reimbursement, but DSM-5 remains the central diagnostic label source in many contexts.
