Presents a study to predict the psychological well-being of adolescents from three theoretical perspectives: family values, acculturation strategies, and social group identity. The participants, living in Norway, were 506 adolescents from four different backgrounds: Vietnam, Pakistan, Turkey, and Chile. The three theoretical perspectives attempt to demonstrate that successful adaptation among immigrants may be a function of how old and new cultures are balanced. Each of these theoretical perspectives has a predictive value depending on the outcome being evaluated. Of the three perspectives, group identity seems to have the strongest predictive value while family values the least for self-esteem, mental health, and satisfaction of life. This study involved high school students who may not represent the norm in the area of immigrant adaptation. Therefore, additional populations should be studied before the findings can be generalized to other immigrant groups. (IP)
