In her dissertation, Nathalie Grabinsky, is investigating the impact of biculturalism on psychological well-being in second generation migrants. Bicultural competence, or the ability to navigate between two cultures, has proven to be a protective factor in migrant mental health. In contrast, identity invalidation has been found to have a negative impact on mental health in individuals who identify biculturally. The aim of this thesis is to explore and analyse the relationship between these factors using both quantitative and qualitative research methodologies. The results of this thesis will contribute to the discourse within the field of psychosocial migration research and provide a greater understanding of migrant mental health in Germany.
