Introduction. The article addresses the development and substantiation of an innovative facilitative technology
for psychological and pedagogical support of adolescents’ emotional and behavioral development. The study’s relevance stems from increasing emotional and behavioral instability among students with mental developmental delay (MDD), requiring comprehensive, scientifically grounded corrective approaches that traditional methods fail to provide. Methodology and Methods. The methodological framework integrates cultural historical theory, principles of the facilitative approach, and contemporary concepts of emotional and behavioral development in adolescents with Major Depressive Disorder. Methods include psychological and pedagogical diagnostics, implementation of experimental technology, pedagogical observation, expert evaluation, and qualitative and quantitative data analysis. Results. The three-module facilitative technology demonstrated effectiveness through increased emotional awareness, reduced impulsive and aggressive behaviors, and formation of stable adaptive patterns. Statistically significant positive dynamics in emotional and behavioral development of adolescents with MDD were confirmed. Scientific novelty. The study conceptualizes the facilitative approach as integration of emotional-cognitive, behavioral, and social-communicative strategies into unified technology, identifying criteria and indicators for dynamics of emotional-behavioral regulation essential for personalized corrective intervention trajectories. Practical significance. The technology provides a comprehensive tool for psychological and pedagogical support systems, including: a support program fostering emotional resilience and correcting behavioral difficulties; a game-based practicum for emotional and behavioral development (GPEBD) targeting negative emotional states; functional modules adapted to MDD characteristics; and an indicator map enabling individualized corrective interventions.
