Diagnosis of borderlines: a discussion.

Area of Science:

• Psychiatry
• Clinical Psychology
• Developmental Psychology

Background:

• Reviews of borderline conditions by Liebowitz (1979) and Rieder (1979) are discussed.
• The author's research on clinical aspects of the borderline syndrome is briefly presented.
• Investigator-specific theoretical positions and diagnostic procedures in borderline condition research are noted.

Purpose of the Study:

• To discuss existing literature on borderline conditions.
• To present the author's research on the clinical aspects of the borderline syndrome.
• To explore the consensus and divergence in the study of borderline conditions.

Main Methods:

• Literature review and discussion.
• Description of the author's own research findings.
• Analysis of theoretical positions and diagnostic evaluations.

Main Results:

• Divergent theoretical viewpoints and diagnostic approaches among researchers are evident.
• A consensus exists that the borderline syndrome represents a basic developmental defect.
• The syndrome is characterized by "stable instability" within four distinct subcategories.

Conclusions:

• The study underscores the complexity and varied perspectives in understanding borderline conditions.
• A developmental defect model provides a unifying framework for the syndrome.
• The concept of "stable instability" offers a way to categorize borderline presentations.
