Este estudio analiza cómo las legislaturas estatales en Brasil instrumentalizan las redes sociales para impulsar el public engagement, conceptualizado como un proceso que abarca desde la difusión de información hasta la participación directa. La investigación examina las tipologías de public engagement promovidas por los contenidos publicados y los factores que condicionan el comportamiento institucional en línea. Los resultados revelan que las legislaturas analizadas mantienen presencia activa en las plataformas, y priorizan contenidos de carácter informativo y comunicación general. La inversión en estas estrategias digitales está más vinculada a la trayectoria tecnológica previa de cada legislatura que a la interacción con los usuarios. Así, estas prácticas fortalecen la representación institucional y consolidan los vínculos entre el parlamento y la ciudadanía en el entorno digital

This study examines how Brazilian Regional Parliaments use social networking platforms to foster public engagement, understood as a process from information provision to citizen intervention. It analyzes the types of engagement generated by posted content and factors associated with institutional behavior online, including followers’ interaction, digital teams, and platform choice. Findings show that all parliaments maintain active profiles on major platforms, prioritizing Communication and Information. Investment in engagement strategies relates to each legislature’s digital trajectory rather than to consistent follower interaction. However, posts focused on Communication and Education generate higher interaction. Overall, digital practices reflect institutional representation strategies aimed at strengthening parliament-citizen connections instead of personalized political communication
