Abstract
Contemporary theories of psychopathology remain divided among disease-oriented, psychosocial, developmental, and constructivist perspectives. Although each explains important aspects of psychological suffering, they often operate at different explanatory levels and therefore appear contradictory. Situated within the broader Developmental Organization Theory (DOT), this article advances a Three-Level Developmental Architecture of Psychopathology as its principal contribution. The architecture distinguishes (1) etiological processes, including biological vulnerability, attachment, trauma, and sociocultural influences; (2) developmental emotional organization, proposed as the comparatively underdeveloped intermediate level through which those influences become coordinated into relatively stable patterns of functioning; and (3) clinical expression, including symptoms, psychiatric syndromes, impairment, and recovery. The Five-Stage Developmental Organization Model is presented as one provisional account of how developmental emotional organization may become progressively differentiated and integrated. Rather than replacing psychiatric diagnosis or established biological and psychosocial theories, the proposed architecture organizes them across complementary levels of explanation and generates testable propositions concerning diagnostic heterogeneity, equifinality, multifinality, treatment response, and durable recovery.
