These consequences are increased by the daily stresses of displacement and life within camps, including ongoing risks of violence, lack of basic services, and uncertainty about the future. Women and girls in camps often fear being alone, especially at night, because of the risk of trafficking and sexual violence. The most prevalent clinical problems among Syrian refugees are depression, prolonged grief disorder, PTSD, and anxiety disorders. However, the perception of mental health is affected by cultural and religious values that result in different modes of expressing distress or making sense of psychological symptoms. In addition, refugees who have experienced torture often endure somatic symptoms in which emotional distress from torture is expressed in physical forms.
