This study assessed the effectiveness of a mental health nurse-led training program to reduce stigma among teachers in Spain. A total of 169 teachers were divided into experimental and control groups. The program included 4 sessions (8 hours total), and stigma was measured using the Stigma Attribution Scale. Results showed a significant reduction in stigma across most dimensions, sustained at three months. Effect sizes were moderate to high for Pity, Coercion, and Segregation. The program proved effective in both the short and long term.engAttribution 4.0 Internationalhttps://creativecommons.org/licenses/by/4.0/Hemorragia SubaracnoideaCarga Global de EnfermedadesFactores de Riesgojournal article10.1001/jamaneurol.2025.1522open accessEpidemiologíaActividad científicaEnfermedadGoal 3: Ensure healthy lives and promote well-being for all at all ages
