Child marriage is not only a violation of human rights but also a practice with profound and long-lasting consequences for young women’s mental health and emotional well-being. It not only affects to individual but also the whole community in the long term due to negative spill-over effects.

Through an analysis of cultural, social, and economic factors, the study examines how early marriage subject’s minority women to emotional distress, social isolation, and a lack of educational and personal development opportunities. These factors often lead to anxiety, depression, and long-term trauma. The research has used survey question combining with interview of 10 minority people to find out the main reasons and address the psychological impact of child marriage, which is essential to propose solutions for this issue.
