The content and predictors of the ethnic identity of Russian-speaking immigrant adolescents (N = 170) in Finland were investigated. The ethnic identity of immigrants was found to be composed of two dimensions, one reflecting the cognitive, evaluative and emotional components of their Russian identity and the other reflecting those of their Finnish identity. The ethnic and linguistic self-identifications of adolescents were strongly related to the extent of and the value given to the Russian and Finnish identity, but neither to the frequency of using nor to their proficiency in the respective languages. The immigrants' perceptions of the relationships with parents were strongly related to their Russian identity. This association was, however, very different for girls and boys. In addition, the Russian contact orientation and Russian language use were strong predictors of the adolescents' Russian identity, whereas their Finnish contact orientation and Finnish language use strongly predicted their Finnish identity.
