This study utilized cluster analysis to identify profiles of emotion regulation (ER) in 196 Chinese children based on ratings from mothers, teachers, and the children themselves. Four clusters were identified: 1) a poor family ER group who received negative ratings only from mothers, 2) a good ER group with moderately positive ratings across informants, 3) a poor school ER group with negative teacher ratings but positive mother ratings, and 4) an excellent ER group with the highest ratings across informants. Children in the inconsistent clusters (poor family and poor school ER groups) showed more psychosocial problems according to teacher reports than those in the consistent good and excellent ER groups, highlighting the importance of a multi-informant approach to understanding ER.
