This study examines changes over time in ethnic affirmation/belonging and ethnic identity achievement, Spanish language use, English language use, Mexican/Mexican-American affiliation/ identification and Anglo affiliation/identification in a sample of Mexican-American adolescents participating in a longitudinal study of juvenile offenders. The Multigroup Ethnic Identity Measure and the Acculturation Rating Scale for Mexican Americans-II were completed by the MexicanAmerican adolescents 7 times over a 3-year period. The findings from longitudinal growth modeling analyses and growth mixture modeling analyses indicate that there is heterogeneity in the initial scores and changes over time on these variables that are related to markers for the cultural qualities of the home environment (i.e., generational status and mother's most frequent language use). In contrast to expectations, marginalized or assimilated acculturation trajectories/types were not overrepresented in this sample of adolescent offenders. Implications for our understanding of the nature of acculturation and enculturation processes and the way these processes are studied are discussed.As a result of immigration and birth rates the ethnic minority populations (i.e., Latinos, Asian Americans, etc.) in the United States are rapidly increasing in absolute and relative size (U.S. Census Bureau, 2004). Further, for some ethnic minority groups, increased exposure to the mainstream culture of the United States has been associated with increased delinquency (Buriel, Calzada, & Vasquez, 1982;Fridrich & Flannery, 1995;Samaniego & Gonzalez, 1999;Vega, Khoury, Zimmerman, Gil, & Warhaheit, 1995;Wall, Power, & Arbona, 1993) and poor mental health (Hovey & King, 1996;Katragadda & Tidwell, 1998;Rasmussen, Negy, Carlson, & Burns, 1997;Rogler, Cortes, & Malgady, 1991). Several authors (e.g., Gonzales, Knight, Morgan-Lopez, Saenz, & Sirolli, 2002;Szapocznik & Kurtines, 1993)

That is, ethnic minority individuals may be at greater risk because they are often expected to adhere to many of the behavioral expectations and values of the ethnic culture in their home and proximal neighborhood while at the same time they are expected to adhere to the behavioral expectations and values of the mainstream culture at school and in the broader community.Although some (e.g., Berry, 2006) describe this dual cultural adaptation under the rubric of acculturation, we describe this dual cultural adaptation as occurring through the processes of acculturation and enculturation (Gonzales et al., 2002;Knight, Jacobson, Gonzales, Roosa, & Saenz, 2009) to diff...
