Abstract
This study examines whether and how disaster collective memory perception is associated with individual preparedness through four proposed mediators: threat appraisal, social norms, coping appraisal, and institutional trust. Using survey data and structural equation modeling via categorical diagonally weighted least squares (WLSMV), the study compares two disaster-affected localities, Mashiki, Japan, and Palu, Indonesia, with national-scope reference samples from Japan and Indonesia. The findings demonstrate substantial contextual variation in the structural pathways linking collective memory perception to preparedness. In Mashiki, collective memory operates under full mediation, translating into preparedness exclusively through localized coping appraisal, reflecting a setting where lived trauma reinforces actionable self-efficacy. In Palu, collective memory robustly enhances internal cognitive appraisals, civic norms, and institutional trust, yet none of these factors translate into household preparedness, revealing a structural uncoupling driven by post-disaster recovery and resource constraints. In the national-scope samples, collective memory exhibits a dual-track pattern characterized by partial mediation, directly sustaining baseline preparedness while channeling indirectly through coping appraisal. Although collective memory reliably cultivates social norms and institutional trust across all contexts, these socio-relational dimensions serve as broader civic foundations rather than direct drivers of private household action. Overall, the findings indicate that collective memory requires actionable coping feasibility and supportive material conditions to effectively foster individual protective behaviors.
