Abstract
Preconception care is considered essential for raising early awareness of health risks among women planning pregnancy, optimizing lifestyle factors, preventing potential perinatal complications, and supporting informed decisionmaking to improve both maternal and child health outcomes. The target group for preconception care is diverse, including women and men with varying backgrounds and health literacy levels. The digital tool ZwangerWijzer (Preparing for Pregnancy) has been validated and is designed to identify preconception risk factors while providing tailored information on topics such as lifestyle, chronic conditions, and hereditary diseases. This study evaluated the usability of ZwangerWijzer, employing the Think-Aloud method and semi-structured interviews with women (n=13). Results showed that users generally perceived the tool as intuitive, wellorganized, and user-friendly. Users also identified room for improvement in content clarity, visual design, and the provision of interactive feedback. Recommendations are provided for further development to enhance accessibility and inclusivity in digital preconception care.
