Methodological guide: "Internal Validity Criteria" grounded in the TCCR

This methodological guide presents the "Internal Validity Criteria" of the Cognosystemic Theory of Human Psychosocial Relational Construction (TCCR) as an endogenous epistemic standard for Social Work. Structured around an operational triad—Inter-level Coherence, Relational Effectiveness, and Relational Justice—the guide offers a verifiable framework for judging the quality of diagnoses, decisions, and interventions from the unit of analysis, the Cognosystem (micro–meso–macro). Validation is operationalized through equivalent instruments—the Meaning Circulation Map (MCM), Mediation Bridges (MB), and the Cognosystemic Decision Chain (CDC)—and a Validation Matrix that applies the "strong-minimum" rule across four planes: traceability (Data→Meaning→Decision→Effect), inter-level alignment, selected indicators, and observable effects. The document includes a step-by-step procedure (with guiding questions), templates for hypotheses and design, and the ICOR indicators (trust, coordination, recognition, conflict management) and VIRE (Voice–Influence–Recognition–Ethics Plan), together with three complete cases (school, neighborhood, workplace organization) that illustrate use, measurement, and loop closures. Its purpose is to build cumulative, endogenous knowledge, enhance disciplinary credibility, and structure practice without bureaucratizing it, offering transparent, auditable, and transferable criteria for professional teams, students, and researchers who intervene from the TCCR perspective.Get the book on Amazon: "Cognosystemic Theory of Human Psychosocial Relational Construction TCCR: A unified theoretical proposal for Social Work"
