The statistical population consisted of 14-year-old football players from a football academy, of whom data from 22 participants meeting the inclusion and exclusion criteria were included in the final analysis. The intervention comprised 12 twenty-minute life skills training sessions developed through a participatory action research approach and delivered immediately before technical and tactical football practices. Data were collected at multiple measurement points using the Cognitive Emotion Regulation Questionnaire and a questionnaire assessing positive and negative processes within coach–athlete–parent relationships. Statistical analyses were conducted using repeated-measures analysis of variance followed by Bonferroni-adjusted pairwise comparisons to examine changes across the pretest, posttest, and follow-up assessments.</p> <p><strong>Findings:</strong> Repeated-measures analysis revealed a statistically significant effect of time on all study outcomes (p &lt; .001). Adaptive cognitive emotion regulation strategies increased significantly following the intervention, with an effect size of 81.8%, whereas maladaptive emotion regulation strategies decreased significantly, with an effect size of 83.9%. Negative processes within coach–athlete–parent relationships also showed a significant decline across measurement occasions, accounting for 60.5% of the observed variance, and this improvement remained stable during the follow-up period. Positive interpersonal relationship processes increased significantly from pretest to posttest and demonstrated an additional statistically significant improvement between the posttest and follow-up assessments, with an effect size of 72.4%. Overall, the inferential findings indicated both immediate and sustained intervention effects on emotional regulation and interpersonal relationship processes.</p> <p><strong>Conclusion:</strong> Integrating culturally adapted life skills training into routine football practice may provide an effective and sustainable approach to strengthening adaptive emotion regulation, reducing maladaptive cognitive responses, and improving the quality of coach–athlete–parent relationships among adolescent football players. The persistence and continued development of several outcomes during follow-up further support the incorporation of such programs into youth football development systems.</p> </td> </tr> </tbody> </table> https://journals.kmanpub.com/index.php/jayps/article/download/6636/12222
