Knowing Who You Are for Not Feeling Lonely? A Longitudinal Study on Identity and Loneliness

In adolescence, both identity concerns and feelings of loneliness are of utmost importance to the experiences of young people. Yet, a theoretically grounded hypothesis that identity and loneliness are developmentally related has never been tested. Thus, the aim of this study was to disentangle the longitudinal associations between identity processes in educational and interpersonal domains and loneliness in adolescence. The sample consisted of 632 Lithuanian adolescents (53.2% girls; Mage = 14.32; SDage = 1.09) participating in a four-wave study with 6-month intervals between assessments. Cross-lagged analyses revealed reciprocal associations between identity processes and loneliness in the educational domain and unidirectional effects of adolescents' reconsideration of commitment on loneliness in the interpersonal domain.
