[Diagnosis and sub-diagnosis of depression]

Area of Science:

• Psychiatry
• Clinical Psychology
• Mental Health Research

Context:

• Current depression models may lack comprehensive symptom categorization.
• Need for validated diagnostic tools in clinical practice.

Purpose:

• To present a novel clinical model for depression.
• To introduce the Tetradimensional Questionnaire for Depression (TEG-DE) as a diagnostic instrument.

Summary:

• The proposed model defines depression through four dimensions: depressive mood, anergy, discommunication, and rythmopathy.
• The Tetradimensional Questionnaire for Depression (TEG-DE) is based on this four-dimensional model.
• TEG-DE demonstrates utility in the diagnosis and classification of depression.

Impact:

• Offers a more nuanced understanding of depressive symptomatology.
• Provides clinicians with a structured tool for depression assessment.
• Potential to improve diagnostic accuracy and treatment stratification for depression.
