Abstract: | ABSTRACT. This case study explored the effectiveness of radio spots promoting school-based sex education and makes recommendations for future advocacy efforts using the transtheoretical model to analyze the populations of Sacatepéquez and Chimaltenango, Guatemala, on their attitudes, beliefs, and behaviors regarding school-based sex education. An in-person community questionnaire was implemented, and a convenience sample of 329 participants was analyzed. Data showed support for school-based sex education among these populations, and this article suggests various strategies for further, more targeted advocacy efforts within these communities. |
