This is a study taking place at the National Institutes of Health (NIH). All caregivers of a child between the ages of 0-25 from a foreign country who have traveled to the United States for the purpose of enrolling in a research protocol and/or seeking treatment for their child s medical condition will be invited to participate in this study. Caregivers who immigrated to the United States for reasons other than obtaining these services for their child s condition will not be eligible to enroll in this study. Given the present demographic populations at NIH, it is expected that participants will include, but not be limited to, individuals from the Caribbean, Dominican Republic, Puerto Rico, Chile, Peru, Guatemala, and Mexico. This sampling frame ensures that the presence of black, white, and mixed race individuals will be represented, acknowledging ethnicities that are often overlooked in studies focusing specifically on the experience of a given ethnic or racial group.
