What is the primary purpose of the DSM-5?

The primary purpose of the DSM-5 (Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition) is to provide a standardized classification and criteria for diagnosing mental disorders. This manual is essential for clinicians, researchers, and mental health professionals because it outlines specific diagnostic criteria that help ensure consistency and reliability in the diagnosis of mental health conditions. By using the definitive criteria set forth in the DSM-5, professionals can accurately identify and characterize the various mental disorders, which facilitates communication among healthcare providers and helps guide treatment decisions.

The other choices represent related aspects of the field but do not capture the primary function of the DSM-5. For instance, while providing treatment guidelines is an important part of clinical practice, the DSM-5 itself is not primarily intended for this purpose; it focuses more on diagnostics. Similarly, identifying healthcare providers is not a function of the DSM-5, nor does it directly address the costs of treatment, which are determined through different healthcare frameworks and insurance policies.
