The aim of this study is to examine the association between citizens' perceptions of the effectiveness of the institutional response, their connection and responsibility to their community (Sense of Community-SoC; Sense of Community Responsibility-SoC-R), and their personal and social concerns about the current emergency and their perceptions of a postpandemic future during the first COVID-19 pandemic lockdown. Another variable considered was the personal reflexivity about the COVID-19 pandemic. 3925 Italian adults completed an online questionnaire during the first COVID-19 lockdown. A structural equation model with mediation was tested. Institutional effectiveness was associated with SoC, SoC-R, current social concerns, and perceptions of a postpandemic future. SoC and SoC-R were associated with current personal and social concerns, and perceptions of a postpandemic future. Reflexivity was negatively associated with SoC and positively associated with SoC-R, mediating the relationships between SoC, SoC-R and current personal and social
