The present study was conducted to determine the effectiveness of parenting skills training based on a solution-oriented approach to internalization disorders in preschool children in District 4 of Isfahan. The research method is quasi-experimental and based on a pre-test-post-test design with a control group. To conduct the research, first one area was randomly selected from the six education districts of Isfahan and then two schools were selected as available. After completing the Children Behavior Checklist Questionnaire - Parent Form (CBCL) by parents, 30 couples of parents who reported the most internalization disorders from their children and met the inclusion criteria were selected and asked to participate voluntarily. Cooperation was requested in the training sessions. These numbers were randomly divided into two groups of 15 pairs of experiments and controls. The parents of the experimental group received parenting skills training based on the solution-oriented approach in 6 sessions of 90 minutes. At the end of the sessions, all samples, both experimental and control, who had not received any training, underwent post-test (again, the children-behavioral checklist completed the parent form). Mann-Whitney and Wilcoxon tests were used to analyze the data. Based on the results, in the experimental group compared to the control group in the post-test phase, a significant decrease in the severity of internalization disorders was observed. The results show that all components of pediatric internalization disorders are significantly reduced. Based on the results of the present study, teaching parenting skills to parents with a solution-oriented approach can be an effective method in reducing internalization disorders in preschool children.
