There were 2 significant findings out of 10 relations for EC. Teacher-rated IM status was predicted by high attentional and inhibitory EC. Teacher-rated D (vs. IM) status was predicted by parent- and teacher-rated impulsivity (2 of 4 analyses for impulsivity). D status also tended to be predicted by anger (1 of 4 analyses) and sadness (2 of 4 analyses). Thus, IM vs. D status was related to somewhat higher EC and less negative emotion and impulsivity at school at T3 when T1 levels of predictors were controlled.
