Drawing upon the empirical operational records of 13 representative universities and domain expert knowledge, an integrated DEMATEL-ISM (Decision Making Trial and Evaluation Laboratory\u2014Interpretive Structural Modeling) approach was employed to analyze the causal relationships and hierarchical driving mechanisms among these elements.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>The PCEWS is comprehensively constrained by multidimensional elements. Financial investment, the formalization of mechanisms, and human resource allocation are identified as the foundational elements, exhibiting the highest centrality and a strong degree of cause. The system exhibits a three-tier hierarchical driving structure: the deep-level financial and institutional elements, through resource injection and institutional empowerment, drive the middle-level data updating processes and systematic training construction. These, in turn, sustain the surface-level outcomes, including the proactiveness of early warnings, cross-departmental collaboration, and the effectiveness of home-school synergy.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>This study rectifies the misconception in PCEWS construction that overemphasizes technology at the expense of management. It provides a scientific decision-making basis and optimization pathways for universities to precisely allocate mental health resources and eliminate operational barriers within the early warning system.<\/jats:p>\n
