Participants completed pre-test and post-test assessments of anti-social behaviors and responsibility using standardized measures. Analysis of covariance (ANCOVA) and pairwise comparison t-tests were conducted to evaluate treatment effects.</p> <p><strong>Findings:</strong> Both group and individual cognitive therapy interventions yielded significant reductions in anti-social behaviors (Group CT: M_pre = 26.35, M_post = 19.65; Individual CT: M_pre = 25.80, M_post = 18.90) and increases in responsibility (Group CT: M_pre = 30.10, M_post = 35.25; Individual CT: M_pre = 29.85, M_post = 35.60) from pre-test to post-test (p &lt; 0.001). Pairwise comparison t-tests indicated significant differences between intervention groups and the control group in both outcome variables (p &lt; 0.001).</p> <p><strong>Conclusion: </strong>The findings suggest that both group and individual cognitive therapy interventions are effective in addressing anti-social behaviors and promoting responsibility among adolescents. These results underscore the potential of cognitive therapy approaches to improve behavioral functioning and enhance adolescents' well-being.</p> </td> </tr> </tbody> </table> https://journals.kmanpub.com/index.php/jayps/article/download/2822/4664
