Background: Suicide is a multi-faceted phenomenon which its incidence is affected by psychological, sociological, and cultural factors. One of these factors is identity which plays an important role in teenagers and young adults. This study aims to investigate the relationship between aspects of identity with suicidal thoughts and its predictive role in the army soldiers in Mashhad.

Materials and methods: The study was a descriptive correlation study which was conducted on 361 soldiers selected by multi-stage cluster sampling in the city of Mashhad, in 2015. The instruments of this study were revised Cheek’s Aspects of Identity Questionnaire and the Beck Scale for Suicidal Ideation (BSSI). The data were analyzed by Pearson correlation coefficient and multiple regression analysis.

Results: Although there were negative relationships between suicidal thoughts and all four aspects of identity (personal, social, collective and relational), only social and relational aspects were significant. In addition, results showed that social identity alone was able to predict suicidal thoughts, significantly.

Conclusion: It seems that suicidal thoughts can be reduced with training the individuals and their families.
