Refugees experience physical problems and extreme psychological as well as emotional stress as a result of the trauma of relocation, loss and the uncertainty of their future. Neglecting refugees' mental strength and social assistance needs can have long-term consequences for the individuals and the host communities. This highlights the need for comprehensive assistance programs that include basic requirements along with mental health treatment, education, skill training and chances for social inclusion. For this vulnerable category, we have limited information regarding social principle interventions at the individual and community levels that support mental health with little scientific data about the effectiveness of such interventions. This systematic review examines 536 publications on social-principle-based treatments for improving the mental health of refugees, 14 of which were chosen for examination. The material from these 14 publications assessed the studies, considering qualifying circumstances. The research results concentrate on many major issues, including mental health measurements, which provide insight into the assessment and evaluation instruments used to evaluate refugees' mental well-being. In addition, we discuss the difficulties that refugees encounter in obtaining appropriate mental health care, the amount of monitoring and its influence on their mental health outcomes. The study emphasizes the significance of tailored treatment options since customizing treatments to individual refugee needs is critical for effective mental health assistance. Finally, we explore the relevance of community-based therapeutic options, highlighting the importance of community engagement and support networks in boosting refugee mental health and well-being.
