[Emotional Problems of Children and Adolescents in the COVID-19-Pandemic: Patterns of Change and Predictors].

The COVID-19-pandemic showed largely negative, but heterogeneous effects on the psychological well-being of children and adolescents.The present study aimed to (1) identify differential trajectories of emotional problems as young people entered the pandemic, (2) compare pre-pandemic trends to changes one year after its onset, and (3) analyze sociodemographic and social predictors of trajectories. 555 children and adolescents, aged 7 - 14 years at T1 (M = 10.53 years, 46.5 % female), were interviewed in three waves of the German family panel pairfam. Latent class growth analysis (LCGA) revealed four distinct trajectories of emotional problems: an increase after the onset of COVID-19 ("Mean increasing"), a decrease ("Mean decreasing"), no change at low level ("Low stable") or at high level ("Chronic high"), each after a stable trajectory before the pandemic.Multinomial logistic regressions showed that females and youth experiencing an increase in financial deprivation were at higher risk of increasing or chronically high level of emotional problems, while sociability proved protective. Migration background and rejection by peers showed mixed effects. The results emphasize the importance of a differential perspective on how the COVID-19-pandemic affected children's and adolescents' well-being. Besides negative consequences for vulnerable groups, also beneficial aspects of the pandemic should be considered.
