Since the national media plays a very prominent role in the extent to which the country's high goals are achieved, the present study aims to "investigate the role of the national media on the national security of the Islamic Republic of Iran," answering the question: "What is the role of the national media on the country's national security?"
The method of this research is descriptive-survey. After accepting the components and related indices, independent and dependent variables were obtained through experts, and a researcher-made questionnaire in a structured Likert scale format consisting of 26 items (with a statistical sample of 145 individuals) was distributed. Statistical analysis of the collected data was performed using SPSS software. Furthermore, considering the research objective, an appropriate scale was employed, and single-sample $t$-tests were used as the research tool, determining the rank mean of homogeneity and heterogeneity, as well as the type of relationship between indices and components in the field of national security.
The findings regarding the three processes of the national media in the country's national security show that the mean of the national media support process in national security is $3.5426$, the managerial process of the national media in national security is $3.2608$, and the main process of the national media in national security is $2.9954$.
The results of the three processes of the national media in national security, taking into account the $t$-value, are $t=3.39$ for the managerial process and $t=6.63$ for the support process of the national media in national security.
At the level of ($p>0.05$), there is a significant difference between the indices of the managerial process and the support process of the national media in national security compared to the theoretical mean of the test (the median of the scale used), such that the indices of the managerial process and support process are significantly higher than average. Also, considering the $t$-value for the main process of the national media in national security ($t=-0.06$) at the level of ($p<0.05$), there is no significant difference between the indices of the main process and the theoretical mean of the test (the median of the scale used).
