Background: In recent years, the development of soft war dimensions has intensified the devastating impacts of social and cultural on the attitudes and behavior of people, especially youth. This study aimed to construct and validate a scale for assessment of soft war vulnerability.

Materials and methods: For this purpose, 340 students were selected by multi-stage cluster sampling and then soft war vulnerability assessment scale national, social, and cultural identity questionnaires were distributed among them. After collecting data, the validity of soft war vulnerability assessment scale was examined `by Cronbach's alpha coefficient, test-retest, and splitting coefficients to determine the psychometric properties. Also, criterion validity was evaluated by national, social, and cultural identity questionnaires. The factor structure was assessed using exploratory and confirmatory factor analysis.

Results: The factor analysis indicated that our new scale contained three factors, including cultural, political, and social aspects. The obtained Cronbach's alpha coefficients of three subscales were 0.81, 0.90, and 0.77, respectively. In addition, test-retest coefficients were 0.79, 0.68, and 0.63 which reflect the stability of the scale. The criterion validity of the questionnaire with other scales indicated desirable convergent and discriminant validity.

Conclusion: Overall, the findings showed that our new scale had good psychometric properties the student's population, and can be used for Iranian studies.
