Mental health of undocumented immigrants in the United States: A systematic review of methodology and findings

This study systematically reviewed the methodology and findings of 24 peer-reviewed studies on psychosocial risk factors associated with the mental health of undocumented immigrants (UIs) in the United States. Of these studies, 14 included quantitative data and 13 were qualitative. The most common recruitment methods were snowball techniques, and most studies used convenience samples of recent UI Latinos. The method of assessing legal status varied, including current versus retrospective undocumented status. Psychological distress, depression, anxiety, and substance use/abuse were identified as prevalent themes. Studies with enhanced methodological rigor are needed
