“…This positive effect might be driven by psychosocial resources that are associated with a well-established self-concept (Back, 2015;Back & Vazire, 2015). In fact, young people who are more sure about themselves are expected to be more flexible in responding to the social environment (Campbell, 1990), to be better able to understand others' needs and to put themselves in their 'shoes' (Smits, Doumen, Luyckx, Duriez, & Goossens, 2011), to have a more accurate relationship perception (Kenny, Kashy, & Cook, 2006;Mund, Finn, Hagemeyer, Zimmermann, & Neyer, 2015), and to become capable of committing to interpersonal relationships in a mature way (Beyers & Seiffge-Krenke, 2010). This is consistent with empirical evidence documenting that high SCC is related to relationship satisfaction and commitment (Lewandowski, Nardone, & Raines, 2010), whereas low SCC is associated with interpersonal problems (Constantino, Wilson, Horowitz, & Pinel, 2006) and loneliness (Frijns & Finkenauer, 2009).…”
