COVID-19 impact and youth wellbeing
Negative COVID-impact predicted a significant 17.2% of the variability in life satisfaction (B = -.117, 95% CI [-.142, -.091], β = -.414, R 2 = .172, adjusted R 2 = .170, F (1,390) = 80.832, p = .000). It also predicted a significant 19.8% of variability in youths internalizing symptoms (B = .086, 95% CI [.069, .103], β = .444, R 2 = .198, adjusted R 2 = .195, F (1,398) = 97.959, p = .000).
Additionally, an independent samples t test revealed that negative COVID-impact was larger for girls (N = 215, M = 21.74, SD = 4.52) than for boys (N = 185, M = 20.15, SD = 4.103), with a mean difference of 1.598, 95% CI [-2.452, -.744], t(398) = -3.679, p = .000, two-tailed (small-medium effect: Cohen’s d = .368). Regression analysis revealed a significant positive relationship between age and negative COVID-impact (β = .112, p = .025).
Mediation of ARM & CRM on youth wellbeing through negative COVID-19 impact
First, additive risk significantly predicted a portion (3.5%) of the variability in life satisfaction (c’: R 2 = .035, adjusted R 2 = .031, F (1,258) = 9.362, p = .002, small effect: f 2 = .036). Then, additive risk significantly related to negative COVID-impact (a: R 2 = .049, adjusted R 2 = .046, F (1,258) = 13.406, p = .000, small effect: f 2 = .05). But, when negative COVID-impact was added to the same regression model, additive risk was no longer a significant predictor for variability in life satisfaction (p = .109), whereas negative COVID-impact was (b: R 2 = .223, adjusted R 2 = .217, F (2,257) = 36.850, p = .000), with a medium to large effect for the full (combined) hierarchical model (f 2 = .287). Thus, the effect of additive risk on life satisfaction seems to be (fully) mediated through negative COVID-impact. The model accounted for a significant 22% of the variability in life satisfaction. With regard to the CRM, abovementioned analyses yielded similar results (c’: R 2 = .029, adjusted R 2 = .025, F (1,258) = 7.616, p = .006, f 2 = .030, small effect, a: R 2 = .028, adjusted R 2 = .024, F (1,258) = 7.411, p = .007, f 2 = .029, small effect & b: R 2 = .224, adjusted R 2 = .217, F (2,257) = 36.987, p = .000, f 2 = .289, medium-large effect). Results are presented in Figure 1.
The analyses were repeated with internalizing symptoms as outcome variable. Additive risk was not significantly related to internalizing symptoms (c’: R 2 = .003, adjusted R 2 = .001, F (1,258) = .799, p = .372), neither after adding negative COVID-impact to the model (p = .376). However, additive risk related significantly to negative COVID-impact (a: R 2 = .049, adjusted R 2 = .046, F (1,258) = 13.406, p = .000, small effect: f 2 = .05, predicting 4.9% variability) and negative COVID-impact accounted for a significant 21.8% of variability in internalizing symptoms (b: R 2 = .218, adjusted R 2 = .212, F (2,257) = 35.848, p = .000, f 2 = .279, medium-large effect). Thus, no mediation, but an indirect relationship between additive risk and internalizing symptoms through negative COVID-impact was found. The CRM-analyses, yielded similar results (c’: R 2 = .001, adjusted R 2 = -.003, F (1,258) = .222, p = .638 & b: R 2 = .218, adjusted R 2 = .212, F (2,257) = 35.872, p = .000, f 2 = .279, medium to large effect). Figure 2 shows a graphical representation of these results and Table 3 shows additional statistics.

Risk clusters in relation to Negative COVID-impact
Hierarchical regression models of risk clusters showed the following: Individual factors was a significant cluster, R 2 = .125, adjusted R 2 = .115, F (3,266) = 12.694, p = .000. However, within the model, only self-control was a statistically significant predictor. Parenting also explained a significant part of the variability (8.4%) in negative COVID-impact, R 2 = .084, adjusted R 2 = .072, F (5,389) = 7.101, p = .000. Within parenting factors, negative interaction with mothers and parental responsiveness were significant predictors. Maternal mental health was significant as a cluster, R 2 = .026, adjusted R 2 = .018, F (3,367) = 3.265, p = .022 (predicting 2.6% variability), with no significant factors within the model. Paternal mental health was not significant, R 2 = 015, adjusted R 2 = .005, F (3,283) = 1.483, p = .219, but within the insignificant model, paternal depression was significant. Family constellation significantly predicted 2.3% of variability in negative COVID-impact, R 2 = .023, adjusted R 2 = .015, F (3,385) = 2.979, p = .031. Within this model the parent-child ratio was the only significant risk factor. Lastly, Demographic factors significantly related to negative COVID-impact, R 2 = .040, adjusted R 2 = .025, F (4,270) = 2.791, p = .027 (predicting 4% variability). Within the demographic factors, SES and paternal educational level were significant. Table 4 shows additional statistics of abovementioned regression models.

The full model of abovementioned significant risk factors significantly explained 22.1% of variability in the negative COVID-impact, R 2 = .221, adjusted R 2 = .201, F (7, 277) = 11.194, p = .000. Within the model SES, self-control, negative interaction with mothers and parental responsiveness remained significant (see Table 5).
