The Children of Divorce Intervention Program (CODIP) is a school-based preventive intervention delivered to groups of children ages 5-14 who are dealing with the challenges of parental separation and divorce. CODIP offers four versions that are developmentally tailored for specific age groups (kindergarten and grade 1, grades 2 and 3, grades 4-6, and grades 7 and 8). The intervention is designed to modify children’s risk and protective factors, including emotion regulation, problem-solving skills, understanding of family changes, anxiety, internalizing problems, and stress-related physical symptoms.
