Positive Youth Development theoretical perspective posits that youth involvement in actions aiming to promote societal change (i.e. social activism) is a marker of their optimal growth. In particular, it claims that immigrant adolescents' engagement in initiatives that foster the progress of host communities is a clear evidence of their positive adjustment. From the PYD standpoint, it is necessary to identify individual and ecological factors that boost youth civic engagement. Among them, multiple social identities and connection seem to play a key role, particularly in those ambiguous contexts, such as the Italian one, in terms of immigration policies and inclusion of foreigners in civic participation. On the basis of these premises, the current study tested a model in which multiple social identities positively influence youth social activism through the mediating role of multiple social connection. This model has been hypothesized to be invariant for Italian and immigrant adolescents who grow up in the same, general developmental context, although they experience different life circumstances. Eighty-six immigrant adolescents (57% male; Mage=17.12, DS=1.73) and 114 Italian adolescents (52% male; Mage=16.68, DS=1.68) took part in the research. They were high school students and they were from southern Italy. Self-report questionnaires were administered including three measures of social identity (national, religious, ethnic/regional), three measures of social connection (perceived legitimacy of authorities, connection with Italian society and the religious group) and one measure of social activism. Data analysis provided for the estimation of alternative mediation models (total and partial) and the invariance between immigrant and Italian adolescents. Results suggest that multiple social connection fully mediate the relationship between multiple social identities and social activism in a sort of process that promotes positive civic engagement among both autochthonous and immigrant youths. Findings provide useful insights that might help in the planning of educational interventions that not only incite adolescents to explore they several social identities but also encourage them to feel part of larger communities and to promote societal change in a constructive way.
