In addition, this study examined the potential influence of gender and age on the relation between the COVID-19 pandemic and externalizing problems. Methods: This study is based on a between-subjects design that examined externalizing problems among children and adolescents between the ages of 8 and 18 years in a youth care sample (N = 3,215) before the COVID-19 pandemic (April 1, 2019–March 10, 2020, N = 1,873) and during the pandemic (March 11, 2020–April 1, 2021, N = 1,342). The Child Behavioral Checklist (CBCL) was used to measure externalizing problems. Parents or legal guardians filled in this questionnaire at the beginning of treatment. Results: No increases in externalizing problems were found in children and adolescents during the COVID-19 pandemic compared to children and adolescents before the pandemic. In addition, gender and age did not influence the relation between the COVID-19 pandemic and externalizing problems significantly. Conclusions: Our results are not in line with most previous research. However, they are in line with recent research that found initial increases in mental health problems at the start of the COVID-19 pandemic, but not over time. This research contributes to the knowledge and sheds new light on the impact of the COVID-19 pandemic on the mental health of children and adolescents referred to youth care.Show less

Additionally, the effectiveness in terms of decrease in aggressive and executive functioning problems of the ‘Minder Boos en Opstandig’ (‘Less Anger and Rebellion’) intervention was investigated in a sample of 13 children (Mage at pretest 9.8 years; 3 girls). Executive functioning was assessed using the Behavior Rating Inventory of Executive Function. The Reactive Proactive Questionnaire was used as a measure of reactive and proactive aggression and the Inventory of Callous and Unemotional Traits was used to assess the influence of callous and unemotional traits. Results showed higher problem scores on the indices of the BRIEF to be uniquely predictive for reactive aggression. Several predictors on subscale level were found for reactive aggression and proactive aggression. Introducing the CU traits to the models of executive functioning as predictors of aggression did not lead to substantial differences. Treatment effects of the MBO intervention were found for both aggression and executive functioning, with significantly lower aggression scores for reactive individuals and a decrease in executive functioning problems. A focus on improving executive functioning in children and adolescents with aggression seems to be important as executive function impairments were associated with both reactive and proactive aggression. The differential influences of executive function impairments on both subtypes provide implications for treatment strategies of aggressive children and adolescents.Show less
