The experimental group participated in a six-session, 90-minute values clarification program, while the control group received no intervention. Ethical reasoning was measured using the Defining Issues Test, Second Edition (DIT-2), and identity stability was assessed with the Ego Identity Process Questionnaire (EIPQ). Assessments were conducted at three time points: pretest, posttest, and five-month follow-up. Data were analyzed using repeated measures analysis of variance (ANOVA) and Bonferroni post-hoc tests with SPSS version 27.</p> <p><strong>Findings: </strong>Results showed significant improvements in both ethical reasoning and identity stability in the experimental group compared to the control group. Ethical reasoning scores increased from a mean of 28.47 (SD = 4.36) at pretest to 35.63 (SD = 5.02) at posttest, and remained high at follow-up (M = 34.51, SD = 5.11). Identity stability scores in the experimental group rose from 91.27 (SD = 7.54) at pretest to 105.46 (SD = 6.72) at posttest, with a follow-up mean of 103.88 (SD = 7.13). ANOVA results indicated significant time × group interaction effects for ethical reasoning (F(2, 54) = 22.15, p = .001, η² = .49) and identity stability (F(2, 54) = 23.55, p = .001, η² = .52). Bonferroni tests confirmed that these improvements were statistically significant and sustained over time.</p> <p><strong>Conclusion: </strong>The findings suggest that the values clarification program is an effective intervention for promoting ethical reasoning and strengthening identity stability, with lasting effects observable at a five-month follow-up.</p> </td> </tr> </tbody> </table> https://journals.kmanpub.com/index.php/jayps/article/download/3842/6440
