This chapter looks at the factors affecting the mental health and emotional well-being of Southeast Asians youth living in the US. Clinical interventions, with case vignettes, are discussed, as well as barriers and challenges to providing culturally competent services. Questions for future discussion of Asian American-Pacific Islander (AAPI) mental health are presented, particularly as it relates to Southeast Asian youth. The authors note that the trauma that immigrants from Cambodia, Laos, and Vietnam who arrived in the US as refugees cannot be overstated. The impact goes beyond those who personally witnessed the war in native land and extends to the sons and daughters who were born and raised in the US. The mental health issues of these Vietnamese, Cambodian, Laotian, and Hmong adolescents are the focus of this chapter. (PsycINFO Database Record (c) 2016 APA, all rights reserved) (Source: chapter)
