The statistical population consisted of children of divorce aged 15–18 years in Babol, from whom 300 participants were selected through purposive sampling. Data were collected using the Iranian Adolescents Risk Taking Scale (2011), Difficulties in Emotion Regulation Scale (2004), Mentalization Questionnaire (2018), Post Traumatic Growth Inventory (1996), and Family Communication Patterns Questionnaire (1990). Data were analyzed using Pearson correlation coefficients, path analysis, moderation analysis, and bootstrap procedures in SPSS and AMOS.</p> <p><strong>Findings:</strong> The results indicated that difficulties in emotion regulation had a significant positive direct effect on risky behavior tendencies (β = 0.41, p &lt; .001), whereas mentalization (β = −0.36, p &lt; .001), post traumatic growth (β = −0.29, p &lt; .001), and family communication patterns (β = −0.31, p &lt; .001) had significant negative direct effects. Furthermore, family communication patterns significantly moderated the relationship between difficulties in emotion regulation and risky behaviors (β = −0.18, p &lt; .001), as well as the relationship between mentalization and risky behaviors (β = −0.15, p &lt; .01). Bootstrap results also confirmed the mediating role of post traumatic growth in the relationship between difficulties in emotion regulation and risky behaviors (β = 0.12, 95% CI [0.06, 0.19]) and between mentalization and risky behaviors (β = −0.12, 95% CI [−0.18, −0.05]). The proposed model demonstrated good fit to the data (CFI = 0.95, TLI = 0.94, RMSEA = 0.054).</p> <p><strong>Conclusion:</strong> The findings suggest that children of divorce with greater difficulties in emotion regulation are more likely to engage in risky behaviors, whereas higher levels of mentalization, post traumatic growth, and constructive family communication patterns serve as protective factors.</p> https://www.journals.kmanpub.com/index.php/aftj/article/download/5548/10310
