Immediately after completing the pre-test, participants attended a single face-to-face educational session during which all five podcast episodes, with a total duration of approximately 00 minutes, were played sequentially under the direct supervision of the researchers to ensure standardized delivery of the intervention. Immediately following the intervention, participants completed the Sustainable Menstrual Hygiene Knowledge Questionnaire as the post-test via Google Forms. The pre-test, educational intervention, and post-test were completed during the same session. After completing the post-test, participants were provided with access to the podcast recordings via a Google Drive link, allowing them to review the educational content voluntarily throughout the three-month follow-up period.
