The hierarchical scaffolding model of executive functioning in university students: a self-reported explanatory approach.

Introduction: Executive functions are cognitive processes that are fundamental to academic success among university students. However, most explanatory models have been developed using laboratory-based tasks, which limits their ecological validity. Self-report measures offer a complementary approach by capturing perceived executive functioning in real academic contexts. Objective: To construct and validate an explanatory model of executive functioning in Cuban university students. Methods: A cross-sectional sample of 1,233 students was analyzed (mean age = 20.08 years, SD = ±1.02; 59.3% women). The Cuban adaptation of the UEF-1 was administered. Analyses combined decision trees using the CHAID method to identify predictors and structural equation modeling (SEM) to confirm the relationships among variables and construct a unified model. Results: The final model showed satisfactory fit (CFI = 0.915, RMSEA = 0.048, SRMR = 0.045). Executive functions were organized into four hierarchical levels: (1) Metacognitive Evaluation and Supervision, comprising Conscious Monitoring of Responsibilities and Behavioral Verification for Learning; (2) Emotional and Behavioral Regulation, comprising Conscious Regulation of Emotions and Conscious Regulation of Behavior; (3) the Operational Attentional System; and (4) Goal-Directed Action and Task Resolution, comprising Decision-Making and Management of Elements to Solve Tasks. Conclusion: The proposed model constitutes the first unified explanatory framework of executive functioning in Cuban university students, specifically as assessed through self-report measures. Its four-level hierarchical structure provides an empirically grounded guide for future research and interventions, capturing the subjective dimension of executive performance as a complementary and ecologically relevant level of analysis closely tied to academic adaptation and self-regulation.
