The study aimed to determine the impact of cultural change on the mental health of migrants and refugees in the United States, including an analysis of mental disorders (depression, anxiety disorders, post-traumatic stress disorder (PTSD), social isolation, stress, and adjustment difficulties) associated with adaptation to new cultural norms and living conditions.

The methodology included an examination of regulatory documents, clinical case studies, comparative analysis, and both theoretical and content analysis. The impact of migration on the mental health of migrants and refugees in the United States was addressed, focusing on legal, social and medical aspects. Real-world cases from refugee clinics in New York (2014–2016) were analysed based on data from U.S. mental health agencies. Committee for Refugees and Immigrants, American Psychological Association, National Immigrant Justice Centre. Unique data were the quantitative and qualitative indicators indicating a high proportion of PTSD, depression and anxiety among refugees (up to 70% of patients).

The study determined that the key barriers to improving mental health are language and culture, uncertain legal status, and lack of access to social support. The results confirmed that a comprehensive approach, including the integration of psychotherapy, medication and social adaptation, is effective for the rehabilitation of this population. The study also emphasised the need to expand health insurance programmes, introduce culturally sensitive approaches to treatment, and develop digital tools for psychological care.

These findings can be used as a basis for further research and the development of new strategies to support the mental health of these groups.
