This paper provides an overview of screening, identification, and assessment tools and processes that can be used by practitioners and researchers who care for immigrant and refugee youth. The authors focus particularly on those tools useful in school-based settings. First, the authors review mental health needs of immigrant and refugee youth and highlight the kinds of issues they may present. Second, they summarize important issues to consider when determining the quality and suitability of screening and assessment measures. They then review existing tools and measures that have been developed to screen refugees and immigrants, as well as those instruments that have been adapted for this use. Finally, they summarize existing measures and issues to consider when conducting comprehensive assessments with these populations. The paper also suggests ways that, in the absence of tools created for a specific refugee population, researchers and service providers can draw from existing tools and modify them to be more useful and appropriate for immigrant and refugee youth.
