Correct Response: B. Helping students, families, and school staff recognize and address factors that foster violence is the most effective way to prevent dating violence. This approach provides a comprehensive strategy that raises awareness among the entire school community, thereby increasing the likelihood of intervention against dating violence. While studying data about dating violence (A) may be a valid element of a health education program, simple exposure to material is a less effective teaching method than getting students directly involved in the learning process. Creating comprehensive policies to deter situations that could lead to dating violence (C) is an action that is appropriate on a schoolwide level, rather than at the level of a single school program. Developing messages for local media to promote appropriate attitudes about relationships (D) could be effective; however, it represents a single project activity by a small group of students and is not as comprehensive as involving the entire school community in preventing dating violence.
