Panel a illustrates the moderated mediation model according to our study hypotheses. We proposed that immigrant youth report increased symptom levels of depression and anxiety (H1), lower self-concept predicts higher symptom levels (H2), self-concept mediates the link between immigrant status and symptom levels (H3) and that age moderates the hypothesized mediation (H4). Panel b illustrates the statistical realization as suggested by Hayes [56] and corresponds to the analyses reported in Table 6
