The Research Domain Criteria Framework: Transforming Psychiatric Research Through Dimensional and Transdiagnostic Approaches

Finite element method (FEM) is used for simulation of two-pass processing tube tension-reducing of the new steel ۳۳Mn۲V for oil well tubes. The simulated results visualize dynamic evolution of equivalent stress, especially inside the work-piece. It is shown that the non-uniform distribution of equivalent stress on the longitudinal and transverse sections is a distinct characteristic of the processing tube tension-reducing, which can be used as basic data for improving tool and technics design, predicting and controlling the micro-structural evolution for manufacturing oil well tubes. The Research Domain Criteria (RDoC) framework represents a paradigmatic shift in psychiatric research, moving from traditional symptom-based categorical classifications toward dimensional approaches grounded in neurobiology and behavior. Launched by the National Institute of Mental Health (NIMH) in ۲۰۰۹, RDoC aims to transform our understanding of mental disorders by investigating fundamental dimensions of functioning that cut across traditional diagnostic boundaries. This comprehensive review examines the development, structure, and implementation of the RDoC framework, its integration with transdiagnostic approaches, and the methodological innovations it has catalyzed. We analyze the six primary domains (Negative Valence Systems, Positive Valence Systems, Cognitive Systems, Systems for Social Processes, Arousal/Regulatory Systems, and Sensorimotor Systems) and their constituent constructs, exploring how they map onto transdiagnostic processes such as rumination, anhedonia, emotion dysregulation, threat sensitivity, and executive dysfunction. The review critically evaluates methodological advances including dimensional research designs, multimodal neuroimaging, genetic approaches, behavioral paradigms, and computational modeling strategies. We address significant challenges facing RDoC implementation, including measurement issues, data integration complexities, and concerns about clinical translation. Finally, we discuss future directions for RDoC-informed research and its potential to reshape psychiatric nosology and clinical practice. The evidence suggests that while RDoC faces considerable challenges, its emphasis on mechanistic understanding and dimensional conceptualization offers promising pathways toward precision psychiatry and more effective interventions for mental disorders.
