Introductions: ACT-PRSK program is an evidence-based approach that was proposed by APA. The present study was carried out in order to examine the effectiveness of ACT-PRSK program in reducing behavioral and emotional problems among preschool children. Methods: The present experiment was a quasi-experimental study that was conducted using a pretest-posttest-follow up design with a control group. The study sample consisted of 32 parents of preschool children that those children had symptoms of behavioral and emotional problems. The participants were randomly assigned into an experimental group and a control one (each containing 16 individuals). The experimental group received ACT-PRSK program. Results: The results of repeated measures MANOVA and Bonferroni test showed that ACT-PRSK program was significantly effective in reducing behavioral and emotional problems except for psychosomatic problems among the experimental parents’ children. Moreover, the effects of the intervention were stable after 2 months. Conclusion: This educational program focuses on parent-child interaction, enhances the parents’ understanding of their children’s behaviors and emotions, and models appropriate behavioral styles, which leads to a change in the parents’ attitude, and thus, results in a change in the parents’ behavior while interacting with their children. It seems that a change in interaction to a large extent leads to a change in the children’s behavior.
