Translating the Transdiagnostic: Aligning Assessment Practices With Research Advances

Area of Science:

• Psychiatry and Clinical Psychology
• Mental Health Research
• Nosology and Diagnostic Systems

Background:

• Current Diagnostic and Statistical Manual of Mental Disorders (DSM-5-TR) framework faces challenges with evidence-based assessment of diagnostic constructs.
• Alternative nosological approaches, such as hierarchical and dimensional models, offer potential improvements over traditional diagnostic systems.
• The Hierarchical Taxonomy of Psychopathology (HiTOP) is a transdiagnostic nosology aiming to address limitations of current diagnostic models.

Purpose of the Study:

• To provide an overview of validated measures for the HiTOP model.
• To review developments in ambulatory assessment practices.
• To outline the integration of HiTOP and ambulatory assessment for advancing measurement-based treatment.

Main Methods:

• Review of ongoing efforts in developing validated measures for the HiTOP model.
• Overview of recent advancements in ambulatory assessment techniques.
• Conceptual framework for integrating transdiagnostic nosologies with dynamic process assessment.

Main Results:

• Development of validated measures for the HiTOP model is progressing.
• Ambulatory assessment methods have advanced significantly, offering insights into dynamic processes.
• Integration of HiTOP and ambulatory assessment holds promise for enhancing measurement-based care.

Conclusions:

• Integrating transdiagnostic nosologies like HiTOP with ambulatory assessment is crucial for evidence-based mental healthcare.
• Further research is needed to fully integrate these parallel developments and address associated challenges.
• This integration can lead to more precise and effective measurement-based treatment strategies for psychopathology.
