Positive Psychology through DRP, DLP/DRL, SDM and D-SDM

This paper develops a comprehensive theoretical framework integrating Digital Relativity Psychology (DRP), Digital Relativity Linguistics (DLP/DRL), the Scretching Diagnostic Model (SDM), and its dynamic extension (D-SDM) with established principles of positive psychology. Drawing upon the PERMA model, broaden-and-build theory, self-determination theory, and the flourishing–languishing continuum, the study explores how psychological well-being, digital interactions, linguistic framing, emotional resilience, and personal development may interact over time. Original contributions include a bounded multidimensional representation of well-being, intervention-sensitive mathematical state-transition models, falsifiable hypotheses, and a structured research protocol distinguishing psychological flourishing from clinical safety assessment. Mathematical identities and illustrative examples are checked for internal consistency, while model parameters, construct validity, predictive accuracy, and clinical applicability remain subject to independent empirical investigation. The resulting synthesis provides a theoretical foundation for interdisciplinary research in positive psychology, digital psychology, cyberpsychology, and computational behavioral science without claiming established clinical validity or experimental confirmation.
