Based on an Interactional Sociolinguistics approach to discourse analysis, this investigation has a discursive aim, namely, that of analyzing the construction of identity of an Italian immigrant in a research interview situation. The analysis focuses on the organization in theme blocks and different dimensions of identity construction. Involvement strategies and its implications for the construction of the narrator s identity, used during the interview, were analyzed based on the statement that narratives are co-constructed by participants in a communicative event. The narrator s identity construction is observed in relation to his professional trajectory and his Italian culture-based attitude. It was observed to which extent the interviewed life story was oriented by Italian cultural values and also his immigrant condition in Brazil. Identity is built simultaneously in three different universes: story, interaction and social-cultural values.
