University Students Adjusting to COVID-19 Stressors: Exploratory and Confirmatory Factor Analyses of the COVID-19 Stressors Questionnaire.

The psychological effects of COVID-19 have been documented in the past year, but scarce literature exists on the nature of COVID-19 stressors. Using a random split sample of 1199 young adult university students, results of exploratory factor analyses (EFA) identified a four-factor structure in the COVID-19 Stressors Questionnaire (C19SQ), which were labeled Resource Constraints, Social Restrictions, Future Uncertainty, and Health Concerns. This model was supported by a confirmatory factor analysis (CFA) when run on the other split sample of 1139 university students.

Implementation of a real-time, data-driven online Epidemic Calculator for tracking the spread of COVID-19 in Singapore and other countries.

While there are many online data dashboards on COVID-19, there are few analytics available to the public and non-epidemiologists to help them gain a deeper insight into the COVID-19 pandemic and evaluate the effectiveness of social intervention measures. To address the issue, this study describes the methods underlying the development of a real-time, data-driven online Epidemic Calculator for tracking COVID-19 growth parameters. From publicly available infection case and death data, the calculator is used to estimate the effective reproduction number, final epidemic size, and death toll.

Mediators of the Associations Between Externalizing Behaviors and Internalizing Symptoms in Late Childhood and Early Adolescence.

This study tests the predictive associations between externalizing behaviors and internalizing symptoms and examines the mediating roles of social competence, parent-child conflicts, and academic achievement. Using youth-, parent-, and teacher-reported longitudinal data on a sample of 523 boys and 460 girls from late childhood to early adolescence, we found evidence for pathways between externalizing behaviors and internalizing symptoms in both directions. Parent-child conflict, but not social competence and academic achievement, was found to be a significant mediator such that externalizing behaviors predicted parent-child conflicts, which in turn, predicted internalizing symptoms.
