School-based mental health interventions have been implemented in Ethiopian youth centers to address behavioural issues among adolescents. A mixed-methods approach combining quantitative surveys with qualitative interviews was employed, with data collected annually from to from youth aged 13-18 in selected Ethiopian youth centers. During the study period, there was a statistically significant decrease (p < 0.05) in reported anxiety symptoms among participants compared to baseline levels, with an estimated effect size of d = 0.62. The findings suggest that school-based mental health programmes can effectively reduce anxiety symptoms among adolescents, although further research is needed to optimise programme delivery and efficacy. Future studies should focus on replicating the study in diverse settings and exploring long-term outcomes of these interventions.
