Various factors were proposed respecting this issue&rsquo;s etiology, ranging from genetic to environmental and familial features. However, mother-child interactions, and especially the mother-child discourse during preschool can impact the formation or reduction of numerous problems in such children. As per different theories, the components of the mother-child discourse are related to the child&rsquo;s mental representations of attachment as well as the child&rsquo;s narrative coherence ability. However, few interventions focusing on children&rsquo;s behavioral problems have particularly addressed the significance of mother-child discourse. Therefore, the present study aimed to investigate the effects of a formulated intervention based on the mother-child discourse model on reducing externalizing problems by reducing negative mental representations and increasing the narrative coherence of children with externalizing problems.<br> <strong>Methods</strong>: This was a quasi-experimental study with a pretest-posttest-follow-up and a control group design. The statistical population of the study consisted of 4- to 6-year-old children with externalizing problems in the kindergartens of the Welfare Organization of Tehran City, Iran, and their mothers in 2018. Twenty-six mother-child couples whose children had externalizing problems were selected using the convenience sampling method. After homogenization based on demographic variables (children&rsquo;s age & gender, and the educational level & occupation of the mothers), they were randomly divided into two groups; 15 couples were assigned per group. At the end of the study, 3 couples in the experimental group (n=12 couples<span dir="RTL">(</span> and 4 couples in the control group <span dir="RTL">)</span>n=11 couples<span dir="RTL">(</span> were excluded. The inclusion criteria of the research for the mothers included having a diploma and the lack of anxiety disorders and depression based on the Diagnostic and Statistical Manual of Mental Disorders, 5th Edition (DSM-5); for children, the same was an age range of 4 to 6 years, receiving a score within the range of externalizing problems (65-69) according to the Child Behavior Checklist (CBC; Achenbach & Rescorla, 2001), and not taking psychiatric drugs. Then, the children were assessed by the CBC concerning externalizing problems. Moreover, the MacArthur Story Stem Battery (Emde et al., 2003) was applied to examine the negative mental representations of attachment and narrative coherence in them. Furthermore, the intervention sessions were entitled &quot;intervention based on mother-child discourse&quot;, i.e., a short-term approach to reduce externalizing problems in children. This package was prepared under the supervision of child psychologists; the content validity method was used to validate the package. The study was conducted in seven 2-hour weekly sessions with 4 sessions for mothers and 3 sessions for the mothers and children. Repeated-measures Analysis&nbsp;of&nbsp;Variance (ANOVA) and Bonferroni posthoc test were used for data analysis in SPSS at the significance level of 0.05.<br> <strong>Results</strong>: The repeated-measures ANOVA data revealed that the main effect of time was significant on externalizing problems (<em>p</em><0.001), the negative mental representation of attachment to the mother (<em>p</em><0.001), and the child&rsquo;s narrative coherence (<em>p</em>=0.020). Moreover, the main effect of intergroup was significant on externalizing problems (<em>p</em>=0.040) and the negative mental representation of attachment to the mother (<em>p</em><0.001). Accordingly, the mean scores of the experimental and control groups were significantly different; however, children&#39;s narrative coherence was not significantly different between the two groups, suggesting that the change over time was the same for both study groups. Besides, the intervention for externalizing problems (F_1.22=116.89, <em>p</em><0.001, Ƞ=0.84), the negative mental representation of attachment to the mother (F_1.22=165.00, <em>p</em><0.001, Ƞ=0.82), and the child&rsquo;s narrative coherence (F_1.22=5.90, <em>p</em><0.020, Ƞ=0.21) were significant. In terms of externalizing problems, the difference between pretest and posttest stages (<em>p</em><0.001), and pretest and follow-up steps (<em>p</em><0.001) was significant; however, there was no significant difference between the posttest and follow-up stages, indicating the persistence of the intervention (<em>p</em>=0.460). Respecting negative mental representation, the difference between pretest and posttest stages (<em>p</em><0.001) and pretest and follow-up steps (<em>p</em><0.001) was significant; however, there was no significant difference between the posttest and follow-up stages, reflecting the persistence of the intervention effects (<em>p</em>=0.170). There was a significant difference between pretest and posttest (<em>p</em>=0.010) and pretest and follow-up stages (<em>p</em>=0.040) in narrative coherence; however, there was no significant difference between the posttest and follow-up stages, demonstrating the persistence of the intervention effects (<em>p</em>=0.560).<br> <strong>Conclusion</strong>: According to the present research results, the intervention based on the mother-child discourse model was useful for reducing externalizing problems, reducing negative mental representations, and increasing the narrative coherence of children with externalizing problems.</div> بازنمایی ذهنی منفی از مادر, انسجام روایتی, تعامل والد-کودک, مشکلات برونی‌سازی, کودکان.
