DSM-5 published

APA publishes DSM-5 after 14 years of revision. Key changes: elimination of the multiaxial system, new disorders, dimensional model for personality.

DSM-5 was the result of 14 years of work by hundreds of experts. Major revisions included elimination of the multiaxial system, reorganization of chapters based on developmental neuroscience, and addition of new disorders such as hoarding disorder and disruptive mood dysregulation disorder.

One of the biggest controversies was the removal of the 'bereavement exclusion' for major depression, allowing depression to be diagnosed during normal grief. Critics warned about the medicalization of normal human experiences.

DSM-5 introduced an Alternative Model for Personality Disorders (AMPD), though the classic categorical model was ultimately retained in the main section due to lack of consensus.

The publication of DSM-5 coincided with NIMH's decision to abandon DSM as a research framework, creating a tension between clinical utility and scientific validity that continues today.

Significance: This is one of the most significant developments in the psychology of our time. Its repercussions continue to be felt years later and have fundamentally changed how we understand the human mind and clinical practice.
