"The key messages that can be drawn from the evidence gathered as part of this review may be summarized as follows: resources should be confidently and generously committed to child and youth safety education programmes that have content that addresses online VAC and related topics; priority should be given to building content about online VAC into existing evidence-based educational programmes, particularly about bullying, because of their well-developed content and design; programmes need to have multiple sessions and multiple modalities and should emphasize acquiring and practicing skills, particularly in the areas of problem solving, assertiveness, empathy, emotion management, self-efficacy, conflict resolution, help-seeking and bystander mobilization; more programme content and messaging is needed to prevent abuse by acquaintances, peers and romantic partners, including content about healthy romantic relationships and how to avoid and terminate unhealthy ones."
