Background and objective Increasing insight, law enforcement knowledge, and using active and passive defense mechanisms have a significant role in crisis management, and many disasters can be solved with these mechanisms in the society. The current research aims to provide a structural equation modeling (SEM) of the relationship between insight and crisis management mediated by passive defense mechanism. Method This is a descriptive survey using SEM method. The study population consists of the employees of Isfahan police department (FAA) in Isfahan, Iran, who had participated in the provincial insight courses (n=240). The sample size was determined using Cochran’s formula. By using simple random sampling method, 148 eligible employees were selected, all of whom were second-level managers. The standard crisis management questionnaires of Jahanbakhsh et al. (2015), a researcher-made insight scale with 14 items, and a researcher-made questionnaire of passive defense with 30 items were used to collect data. To analyze the data and test the hypotheses, correlation test, stepwise multiple regression analysis, and SEM were used in SPSS software, version 20 and Smart PLS software, version 3. Results The findings showed that insight and its components together with passive defense had a significant relationship with crisis management. The variable of passive defense also had a significant mediating role in the relationship between insight and crisis management. Conclusion increasing insight is one of the important factors in improving the quality of crisis management along with paying attention to the dimensions and components of passive defense. One of the strengths of this study was the attention to the hidden layers of crisis management in the performance of police missions. By understanding the concept of passive defense, the relationship between insight and crisis management can be understood and it can be used to prevent and deal with internal and external threats.
