The CRISSCROSS project is a comprehensive, evidence-based initiative that addresses the intersections between gender-based violence (GBV), including sexual harassment, anti-LGBTQIA+ hostility, and the risks associated with substance use1 in nightlife and other spaces of socialization and leisure. These environments, conceived as places of social interaction and entertainment, also reflect and reproduce structural inequalities, contributing to the normalisation of violence and risk dynamics, including, those related to gender and sexuality. Transforming them into safer, more inclusive, and respectful spaces, especially for individuals and social groups in vulnerable situations or at greater risk, requires specific and sustainable interventions adapted to local needs. Based on a participatory and inclusive approach, the project employs the Behaviour Change Wheel Model (BCW) (Mitchie et al., 2014) to design interventions tailored to local needs, combining sensitisation, training, and the improvement of leisure spaces. The BCW is a framework designed to facilitate behaviour change by focusing on three elements: capability, opportunity, and motivation. It uses strategies, such as education, persuasion and environmental restructuring to influence these factors through targeted interventions, making it adaptable to diverse local contexts. In addition, the project integrates bystander intervention models (Latané & Darley, 1972; Quigg et al., 2024) to empower young people in nightlife settings to identify and intervene in risk situations, promoting shared responsibility and the proactive prevention of violence. Its transnational and evidence-based nature promotes substantial change in these environments, ensuring the sustainability and scalability of actions at a European level by designing, implementing, and prioritising equality, safety, and collective well-being.

This report aims to provide a strategic framework for the design and implementation of public policies based on the lessons learned and the results obtained from local interventions carried out at festivals, club nights, public spaces in nightlife areas, and other educational settings in cities across five European countries: Sant Cugat (Spain); Lisbon, Viana do Castelo, Porto, Montargil and Crato (Portugal); Milan (Italy), Dublin (Ireland), and Luxembourg (Luxembourg). These interventions have made it possible to identify both the specific needs of the environment, and the best practices for prevention, awareness, and response to violence in nightlife environments...
