Note: Correlations are between lability and mean levels of self-concept and competence in academic domain (top left), social domain (top right), and mental health (bottom); “iMean” = individual-level within-subject mean across time, “iLability” = individual-level lability, calculated as the within-subject standard deviation of residuals around each child's own growth curve; Bolded values are used to highlight the correlations of self-concept lability with mean levels of self-concept, competence, and mental health variables;
