Prevention Programmes for Urban Violence Exposure and Their Impact on Mental Health and Academic Performance Among Nigerian Youth

Urban violence exposure is a significant public health concern among Nigerian youth, affecting mental health and academic performance adversely. A mixed-methods approach involving pre- and post-intervention assessments with a sample size of 200 participants from urban schools, utilising questionnaires for data collection. Participants reported significant reductions in perceived stress (p=0.03) and improved academic scores (mean increase: 15% in GPA) after participating in the prevention programmes. Prevention programmes effectively reduce exposure to urban violence, leading to better mental health and academic performance among Nigerian youth. Schools should integrate comprehensive violence-prevention curricula into existing educational frameworks to support students' holistic development. Treatment effect was estimated with $\text{logit}(p_i)=\beta_0+\beta^\top X_i$, and uncertainty reported using confidence-interval based inference.
