Acadians from the South-East region of New Brunswick are confronted with assimilation pressures from Anglophones and the demands of a French standard. The rejection-identification model (Branscombe, Schmitt, and Harvey, 1999) and the self concept model (Taylor, 1997, 2002) are tested in order to examine how adolescents of Acadian heritage respond to social disadvantage. Overall, 36 Acadian adolescents from the South-East region of New Brunswick participated in a semi-structured interview. Participants expressed a burden of inferiority next to Francophones from Québec. Different views were expressed concerning attitudes towards Anglophones that resulted in six identity profiles. Results supported the influence of majority out-groups on the collective identity trajectory of Acadian youth. In addition, the analysis revealed that youth who have reported a bilingual with an English orientation profile were more likely to experience difficulties with their psychological well-being.
