The statistical population consisted of female students enrolled in public schools in Shiraz during the 2024–2025 academic year. Using multi-stage cluster sampling, 44 students were randomly assigned to two groups: an experimental group and a control group (22 participants in each group). The research instruments included the Self-Efficacy Questionnaire (Morris, 2001) and the Personal Growth Initiative Scale (Robitschek, 1998). The experimental group received the creative problem-solving skills training package over eight 45-minute sessions, whereas the control group received no intervention. Data were analyzed at the descriptive level (mean and standard deviation) and at the inferential level (mixed repeated-measures analysis of variance) using SPSS version 26.</p> <p><strong>Findings: </strong>The results indicated that the creative problem-solving skills training package had a statistically significant effect on increasing self-efficacy and personal growth initiative (p &lt; .05). The one-month follow-up demonstrated that the improvements in self-efficacy and personal growth initiative remained stable in the experimental group, whereas in the control group, no statistically significant differences were observed between the pre-test and follow-up stages for either variable.</p> <p><strong>Conclusion: </strong>The findings of this study suggest that the creative problem-solving skills training package can effectively enhance self-efficacy and personal growth initiative among first-cycle secondary school students. These results have practical implications for educational and counseling programs aimed at promoting students’ cognitive, social, and emotional competencies.</p> </td> </tr> </tbody> </table> https://www.journals.kmanpub.com/index.php/jayps/article/download/5047/9147
