What is the DSM-5 and its purpose in psychology?

• C. A guide for pharmacological dosing in psychiatry.
• D. A classification system only used by psychiatrists for billing.

Answer: (B)

DSM-5 is the Diagnostic and Statistical Manual of Mental Disorders, fifth edition. Its purpose is to provide standardized criteria for diagnosing mental disorders, giving clinicians a common language and clear thresholds for symptoms, duration, and level of impairment. This standardization supports reliable communication, consistent diagnostic labeling, and informed treatment planning and research across mental health professionals. While it includes cultural considerations, its primary role is not as a cultural assessment tool or a pharmacological dosing guide, and diagnoses are used by a wide range of practitioners beyond psychiatrists, not just for billing.
