Our statistical population comprised all high school students (second level) in Tehran City, Iran. Following Kline&rsquo;s (2016) recommendations, 353 students were selected through random sampling of the multi-stage cluster. Assessment tools included the revised adult attachment scale, the emotion regulation questionnaire for children and adolescents, and the personal responsibility assessment. The data were analyzed using the AMOS software, version 24.0, with maximum likelihood estimations.<br> <strong>Results</strong>: The findings revealed a positive and significant indirect path coefficient between secure attachment style and responsibility through reappraisal strategies (&beta;=0.105, P=0.001) and suppression (&beta;=0.091, P=0.001). The indirect path coefficient between avoidant attachment style and responsibility through reappraisal strategies (&beta;=-0.099, P=0.001) and suppression (&beta;=-0.068, P=0.007) showed negative and significant associations. Similarly, the indirect path coefficient between ambivalent attachment style and responsibility through reappraisal strategies (&beta;=-0.105, P=0.001) and suppression (&beta;=-0.065, P=0.012) demonstrated negative and significant relationships.<br> <strong>Conclusion</strong>: The structural model exhibited an equivalent fit for both male and female groups. Attachment style significantly influences adolescents&rsquo; responsibility, and emotion regulation and management contribute to increased responsibility in adolescents.</span></span></span></div> Attachment style, Emotion regulation, Responsibility 213 224 http://jpcp.uswr.ac.ir/browse.php?a_code=A-10-999-1&slc_lang=en&sid=1 Shima motevasselian mtvslnn@gmail.com 0009-0005-0391-8743 No Department of Psychology, Faculty of Literature and Humanities, North Tehran Branch, Islamic Azad University, Tehran, Iran.
