Introduction: Many children who experience emotional and behavioral problems in early childhood do not simply outgrow them; rather, these issues may continue into adolescence and even adulthood. This study aimed to compare the effectiveness of Parent Management Training - Oregon Model (PMTO) and Barkley Parent Training (BPT) on emotion regulation in children with externalizing problems aged 7 to 10. Methods: This research was applied and semi-experimental in design, utilizing a pretest-posttest and follow-up with a control group. The statistical population comprised all children with externalizing behavioral problems aged 7 to 10 (first to fourth grades) in the academic year 2023-2024 in Zarinshehr County. 60 mothers with children with externalizing disorders who met the inclusion criteria were recruited into the study using convenience sampling. The research instruments included the Achenbach Child Behavior Checklist (1991) and the Gross and John Emotion Regulation Questionnaire (2003). The PMTO and BPT interventions were conducted over 2 months, with 10 weekly sessions of 120 minutes each for the participants in both experimental groups. Results: The results indicated a significant difference in emotion regulation scores between the experimental and control groups in the post-test phase (P < 0.001). In other words, there was a considerable difference in the variable of emotion regulation between the PMTO and BPT training groups at the level of P > 0.05. The comparison of adjusted means demonstrated that PMTO was more effective. Additionally, both treatment groups showed significant differences with the control group at the level of P > 0.01, with PMTO exhibiting greater and significant effectiveness. The Bonferroni test results indicated a significant difference in cognitive re-evaluation between the PMTO and BPT groups (P > 0.05), as well as a significant difference between both treatment groups and the control group (P > 0.01) Conclusion: According to the results obtained, the PMTO model helps parents develop specific behavioral skills, contributing to the creation of a more structured, predictable, and positive home environment. Furthermore, Barkley’s Parent Training, which emphasizes the complexity of behavior and addresses emotional, developmental, and contextual relationship issues while equipping parents with skills to foster a nurturing environment, contributes to the enhancement of long-term positive outcomes.
