多重突发事件中群体心理安全风险的生成演变与媒介化治理OACHSSCD

Frequent multiple-emergency events and their dissemination within deeply mediatized envi-ronments substantially aggravate public psychological-security risks and challenge traditional social-risk-governance models dominated by physical rescue and administrative control.Systematic analysis of mediatized-dissemination features for multiple emergencies shows that collective psychological-se-curity-risk generation constitutes a dynamic process where physical event stimuli gradually evolve into broad-based social-psychological crises.This process unfolds across four phases:event impact,media amplification,emotional contagion,and cognitive bias.Deep media involvement in risk evolution grants the media dual roles within governance structures beyond the traditional information-intermediary function:the media operate both as governance subjects with agenda-setting,public-opinion-supervi-sion and consensus-building capacities,and as governance instruments for information transmission,public-opinion assessment and social mobilization.To build mediated-governance models for collective psychological-security risks,public psychological security should be taken as core governance objec-tive.Public trust and psychological resilience shall be strengthened through transparent and authorita-tive information supply,interpretable risk communication and accessible psychological services.The model emphasizes collaborative governance among government bodies,media outlets,platforms,ex-perts and the general public.It promotes linkage and coupling across three layers:institutional-layer policies,regulations and ethical norms;platform-layer artificial-intelligence and big-data technical sys-tems;and practical-layer risk communication and psychological intervention.It forms a four-step tech-nical-governance closed-loop covering data monitoring,intelligent assessment,precise intervention and effect evaluation,ultimately shifting mediated governance from post-event response toward whole-process coverage.
