Towards an Integrated Staging Model for Bipolar Disorders: An International Society for Bipolar Disorders (ISBD)...

Area of Science:

• Psychiatry
• Clinical Psychology
• Neuroscience

Background:

• Clinical staging models for bipolar disorder (BD) have historically focused on different aspects of the illness.
• Existing models lack a unified approach to capture the multifaceted nature of BD progression.

Purpose of the Study:

• To integrate three existing clinical staging models for bipolar disorder into a single, comprehensive three-dimensional staging model.
• To separately assess bipolar spectrum, nonmood psychopathology, and inter-episodic functional impairment.

Main Methods:

• A task force convened through meetings, Delphi surveys, and email discussions to reach consensus.
• The consensus process focused on the model's structure and stage definitions.
• The model was developed by integrating existing staging approaches.

Main Results:

• A three-dimensional staging model for BD was developed, rating mood psychopathology (M0-M4), nonmood psychopathology (N0-N4), and functional impairment (F0-F4) independently.
• Specific stages were defined for each dimension, including prodromal stages and varying levels of comorbidity and impairment.
• Case vignettes were created to illustrate the model's application.

Conclusions:

• The proposed three-dimensional model offers a comprehensive framework for understanding the complex and heterogeneous progression of bipolar disorder.
• This model accounts for psychiatric comorbidities and functional impairment, providing a more holistic view of the illness.
• Further validation in research and clinical practice is required.
