Emerging adulthood is the period of the life cycle, between 19 and 29 years of age, in which young people in developed countries, although legally adults, have not fully acquired the roles that define them as such. Emerging adults find themselves in a kind of limbo in which they are neither adolescents nor fully adult persons, which generates demands and needs, risks and opportunities that require a social response. This response should take into account the gender perspective, as there is ample evidence that gender is a fundamental and determining dimension of development. The aim of the symposium is to support with empirical evidence the knowledge of emerging adulthood in Spain and to provide clues for future interventions to increase well-being during these years. Four papers will be presented by prestigious national teams interested in the study of emerging adulthood. Professor Javier García Manglano's team will analyze the process of psycho-social maturation during these years, using the Identity Capital Model (Coté, 2016). Professor Milagros Sáinz will focus on the transition of young people to post-compulsory studies, presenting results on their health and degree of satisfaction according to gender and the type of post-compulsory studies chosen. Professor Jorge Manuel Dueñas will analyze the relationship between coming out of the closet in different social environments and its relationship with subjective well-being in LGBTI+ people. Finally, Professor Mari Carmen García-Mendoza will discuss the influence of family relationships on identity development through the Dual Cycle Model (Luyckx et al., 2005). All papers will be based on the gender perspective.
