Purpose of the Study:

• To advocate for the application of early intervention principles in BPD diagnosis and treatment.
• To present a staging model for guiding BPD intervention development.

Main Methods:

• Reviewing evidence for early detection and intervention in BPD.
• Developing a clinical staging model for BPD.

Main Results:

• BPD symptoms emerge in adolescence and are distinguishable from normative development.
• BPD has a gradual onset with progressive social and professional impact.
• Early, adequate treatment shows promise for emerging BPD, while inadequate treatment can cause harm.

Conclusions:

• Early intervention and clinical staging can enhance assessment and treatment of severe psychopathology like BPD.
• Findings have implications for research, mental health policy, and societal understanding of BPD.
