Abstract
Adolescence is a critical developmental stage marked by significant psychological and social challenges. Effective interventions during this period are essential for fostering long-term mental health. Hence, a true experimental pretest-posttest control group design involving 20 ninth-grade students from government-aided and private schools in Coimbatore, Tamil Nadu was completed. The eight-week nurse-led intervention included sessions on emotional self-awareness, stress coping, resilience building and mindfulness. The intervention group exhibited significant improvements in emotional regulation (mean increase of 9.8, p < 0.001) and resilience (mean increase of 22.6, p < 0.001) compared to the control group, which showed no significant changes. Further, a moderate positive correlation (r = 0.35, p = 0.05) was observed between gains in emotional regulation and resilience within the intervention group.
