In today's world, many individuals report difficulties in maintaining a sense of connection, both with others and with themselves. Building on classic theories, this connection can be understood as relational: the ability to be intimate with others rests on the ability to know and understand oneself. Identity can be conceptualized far more broadly, encompassing narrative, sociocultural, and developmental perspectives, as well as the dimensions of distinctiveness, continuity, and coherence. Limited research has demonstrated links between identity commitment and intimacy in romantic relationships, yet romantic relationships are central to young adults' well-being, and a key component of an individual's evaluation of their overall quality of life.


To address this gap, a mixed method, international study was conducted in six European countries - Portugal, Spain, Poland, Belgium, Austria, and North Macedonia - with young adults aged 18-40. In Phase 1, structured interviews with 10 participants per investigator were used to refine culturally sensitive measures and generate qualitative insights into the themes, motives, and identity aspects associated with intimacy. In Phase 2, approximately 200 individuals per country will participate in survey-based research, ensuring balanced gender representation. This phase aims to confirm and extend the findings of Phase 1 within a larger sample using complementary methodology.


By integrating quantitative and qualitative findings, this study will advance understanding identity development and relational well-being in emerging adulthood. Importantly, its contributions extend beyond theory: the results will provide insights for psychologists working in counseling, psychotherapy, and relationship education. By addressing identity and intimacy together, and with a cross-cultural scope, the study will contribute to applied psychology's mission of enhancing individual and relational well-being in contemporary Europe.
