The book "Testing Effectiveness of Edu-Entertainment Health Focused Soap-Opera" by Jesus Arroyave examines the effectiveness of entertainment-education (E-E) interventions in the health sector. By applying both quantitative and qualitative methods, it analyzes which specific variables can make the communication strategy more effective. The focus is on the length of the E-E series and the subsequent discussion sessions, which are evaluated in terms of cognitive, attitudinal, and behavioral outcomes. The results show that the length of the E-E series has no significant impact on the overall effectiveness of the intervention, while the discussion sessions after watching the series lead to significant improvements in the aforementioned areas. The book provides valuable insights for future E-E interventions and offers recommendations for further research.
