Aggression hinders development in the child and creates numerous problems in the family, school and community. An indigenous Anger Coping Training program for Chinese children with aggressive behavior and their parents aimed to help reactively aggressive children in increasing anger coping methods and enhancing problem-solving abilities. This research program uses a mixed model research method based on experimental and control groups with pre-comparison and post-comparison. Qualitative data collection of the children's behavior, as well as the parenting styles and behaviors, were assessed through structured interviews (children, parents and teachers) and the utilization of hypothetical scenarios. Quantitative data collection consisted of the completion of the Child Behavior Checklist and the Child Behavior Checklist Teacher's Report Form. Two pilot studies and the main study were conducted. The program was effective in lessening children's aggressive behavior and changing children's cognitive characteristics, behavioral presentations and affective reactions in post-intervention and follow-up studies.
