Despite the program's intention to facilitate assimilation, many of the Lost Boys still face difficulties in adapting to life in The United States, Canada, or any of the European countries that offered refugee resettlement.[17] Posttraumatic stress, separation from loved ones, cultural isolation, racism and discrimination against the refugees made assimilation extremely difficult.[18] Many studies have discussed a common condition among the Lost Boys of ambiguous loss. This occurs when someone experiences the loss of a family member without the closure of death, which allows for mourning and moving forward.[18] Moreover, a 2005 study found that 20% of Lost Boys under the age of 18 suffered from symptoms of post-traumatic stress disorder.[19] Resettlement to the US made it easier for many of the Lost Boys to reconnect with family members via western technology. However, it was often difficult to reunite if the boys were already in the US and the families remained in camps.
