emphasis is made on studies that have examined the ethnic identity development of Hispanic and African American adolescents and how this construct relates to various measures of mental health. Qualitative and quantitative research that evaluated the developmental model of ethnic identity is presented. Research that relates ethnic identity to several positive aspects of psychological development is reviewed. Also, research that has conceptualized ethnic identity within a resiliency framework is described. Lastly, research that has compared levels of ethnic identity to various mental and behavioral problems is reviewed. Ethnic Identity Development The majority of the research on ethnic identity development has been done with adolescents and adults. The concept of ethnic identity development prior to adolescence has been discussed only as it relates to racial or ethnic socialization (e.g., Bowman & Howard, 1985; Caughy, O'Campo, Randolph, & Nickerson, 2002; Rotheram & Phinney, 1987; Thornton, Chatters, Taylor, & Allen, 1990). Rotheram and Phinney (1987) defined ethnic socialization as "the developmental processes by which children acquire the behaviors, perceptions, values, and attitudes of an ethnic group, and come to see themselves and others as members of such groups" (p. 11). This definition clearly links ethnic socialization to the development of ethnic identity, the aspect of identity related to ethnic group membership. Ethnic socialization practices and their long-term effects on ethnic identity development, however, rarely have been studied. Research with African American families has focused on the many facets of racial socialization (Bowman & Howard, 1985; Caughy et al., 2002; Thornton et al., 1990). In general, the majority of African American parents do provide some level of racial or ethnic socialization. Developing racial or ethnic pride is only one part of this process.
