Which framework studies symptom domains such as psychosis and cognition by linking them to neural mechanisms?

• A. DSM-5-TR diagnostic criteria
• B. Biopsychosocial model
• C. ICD-11 criteria
• D. RDoC framework

Answer: (D)

The main concept is a research framework that ties symptom domains like psychosis and cognitive deficits directly to neural mechanisms. This is what the RDoC framework does: it investigates mental phenomena by mapping them onto neural circuits and biology, across multiple levels of analysis (from genes and molecules to circuits and behavior) and across traditional diagnostic boundaries. It’s a dimensional, transdiagnostic approach designed to understand how brain systems give rise to symptoms, rather than just naming disorders. DSM-5-TR and ICD-11 provide diagnostic criteria for clinical classification based on observed symptoms, not on linking those symptoms to underlying neural mechanisms. The biopsychosocial model emphasizes biological, psychological, and social factors in illness, but it doesn’t offer a structured framework specifically aimed at connecting symptom domains to neural circuitry in a research-first way.
