Trajectories of social withdrawal and social anxiety and their relationship with self-esteem before, during, and after the school lockdowns.

The closure of schools during the COVID-19 pandemic affected adolescents' social withdrawal and social anxiety. Yet, self-esteem may have acted as a protective factor during this period. This study aimed to compare the trajectories of social withdrawal and social anxiety before (Year 1), during (Year 2 and 3), and after (Year 4) the closure of schools imposed by the COVID-19-related lockdowns, and to investigate the association of self-esteem with these trajectories. Participants were 844 (50.6% boys) Portuguese adolescents (mean age 12.70 years, SD = 1.14). The Social and Emotional Competencies Evaluation Questionnaire (QACSE) was used to assess social withdrawal and social anxiety, while The Global Self-Esteem scale of the Self-Description Questionnaire II was used to measure self-esteem. Growth curve analysis showed that social withdrawal and social anxiety had more negative trajectories during the year in which the school closures occurred. In addition, adolescents reported higher social withdrawal after the lockdowns than before the pandemic. Higher self-esteem was associated with a more positive trajectory in social withdrawal. Therefore, the results showed the negative of impact of the closure of schools on adolescents' social anxiety and social withdrawal, and that self-esteem was a protective factor during these challenging and adverse events.
