The statistical population included all female students studying in lower secondary schools in Tehran during the academic year 2023–2024. A total of 385 participants were selected using a multistage cluster random sampling method. The study employed the Risky Behaviors Questionnaire by Zadehmohammadi et al. (2008), the Psychological Capital Questionnaire by Luthans et al. (2007), the Attachment Styles Questionnaire by Hazan and Shaver (1987), and the Cognitive Emotion Regulation Questionnaire by Garnefski et al. (2001). Data were analyzed using Pearson correlation and structural equation modeling (SEM) through SPSS v27 and LISREL v8.8.</p> <p><strong>Findings: </strong>The findings revealed that psychological capital, secure attachment style, and positive cognitive emotion regulation had a significant negative direct effect on risky behaviors. In contrast, avoidant insecure attachment style and negative cognitive emotion regulation had a significant positive direct effect on risky behaviors. The results for the indirect effects showed that the relationship between psychological capital and attachment styles with risky behaviors was significantly mediated by cognitive emotion regulation (P &lt; .05).</p> <p><strong>Conclusion: </strong>Based on the findings, understanding the elements that may influence adolescents' propensity toward risky behaviors is crucial for designing effective intervention strategies to prevent such behaviors.</p> https://maherpub.com/index.php/jndd/article/download/568/443
