Developmental antecedents of young adults' solidarity during the Covid-19 pandemic: The role of sympathy, social trust, and peer exclusion from early to late adolescence

This study explored characteristics of young adults' solidarity during the Covid-19 pandemic by identifying three different profiles, characterized by low (23%), average (54%), and high solidarity (23%). Based on longitudinal Swiss panel data (N-T1 = 797, M-age T1 = 12.15 years, 51% female; 28% migration background representing diverse ethnicities; N-T2 = 707, M-age T2 = 15.33 years; N-T3 = 596, M-age T3 = 18.31 years), the study combined person- and variable-centered approaches to examine whether sympathy, social trust, and peer exclusion at earlier phases in development predicted membership in pandemic-related solidarity profiles (N-T4 = 300, M-age T4 = 20.33 years). All developmental predictors were significantly associated with the likelihood of expressing solidarity during the pandemic as young adults.
