This 1-year follow-up study investigated the direct and indirect effects of past, anticipated, and actual experiences of inter-group interactions on the development of national identity and attitudes towards the national majority among ethnic re-migrants (N= 141) from Russia to Finland. According to the results, the quality of past inter-group contact in the pre-migration stage (T1) did not directly affect national identification and out-group attitudes in the post-migration stage (T2). Instead, the effect of contact quality at T1 on national identification and out-group attitudes at T2 was indirect via perceived discrimination and out-group rejection at T2. In addition, there were two indirect pathways from out-group attitudes at T1 to national identification and out-group attitudes at T2, via pleasant contact experiences (further associated with positive out-group attitudes) and via perceived discrimination (further associated with negative attitudes and lower national identification) in the post-migration stage. Anticipated discrimination only had a direct effect on out-group attitudes in the post-migration stage. The results highlight the role of past and anticipated inter-group relations in the formation of post-migration inter-group interactions, which, in turn, are decisive for the formation of national identification and out-group attitudes of re-migrants.
