Positive Monitoring	5.36 / 6 (1.29; 0-6)	5.59 / 6 (1.05; 0-6)	0.09a	5.07 / 6 (1.47; 0-6)	5.49 / 6 (1.18; 0-6)	< 0.01a

Child, children; m, months; Adolesc, adolescents; SD, standard deviation; p, p value from the t test for independent samples.

Item responses for the IEPMB range from 0 to 10 from Aggressiveness and emotional dysregulation, and from 0 to 6 for Relaxed Discipline and Positive Monitoring. For Positive Monitoring higher scores indicate better parenting practices, and for the other two practices higher scores indicate worst parenting practices.
