This publication presents findings from a national study examining the knowledge and attitudes of grassroots family health workers in Sri Lanka regarding contraceptive methods and their ability to communicate information to clients. It shows that while overall knowledge of contraceptive methods among health workers is generally high, there are notable gaps, particularly concerning newer methods like injectables and traditional methods such as rhythm. The study identifies significant training needs, especially in areas such as contraceptive safety, method effectiveness, contraindications, and communication techniques. It also reveals biases in attitudes, with a preference for certain modern methods (e.g., IUDs) and less favorable views toward condoms and traditional methods, potentially affecting client choice. The report concludes that strengthening in-service training and improving information, education, and communication practices are essential to enhance family planning programme effectiveness and informed decision-making by clients.
