The present study, conducted between January and March 2026, adopted a systematic review approach to examine the prevalence of mental disorders, risk factors associated with the migration process, and migrants’ access to mental health services. To gather the required data, the online databases PubMed, Scopus, ScienceDirect, Google Scholar, the Scientific Information Database (SID), and Noormags were searched. Search terms consisted of the keywords mental health, stress, trauma, immigrant, refugee, and migration in both Persian and English, along with their combinations. The final review was conducted on 31 articles published between the beginning of 2000 and the end of 2025 (along with a number of related classic sources). The findings indicate that refugees are at a higher risk of developing mental disorders compared to voluntary migrants, with the prevalence of depression and post‑traumatic stress disorder among refugees each estimated at approximately 32%, and the prevalence of anxiety at approximately 11%. Certain individual and social factors, including gender, pre‑migration conditions, and acculturation patterns, contribute to explaining the observed differences. Furthermore, barriers such as language limitations, social stigma, and unfamiliarity with service systems challenge effective access to mental health care. In conclusion, depending on individual and social contexts, migration can be associated with increased psychological vulnerability; therefore, developing culturally sensitive interventions and strengthening support networks appear essential to meet the diverse needs of migrants.
