Introduction: The Lights4Violence project was created to promote healthy relationships among adolescents using a school intervention in which participants developed video-capsules where they highlighted skills to resolve situations of dating violence. This study aims to assess the results of the Lights4Violence training program by identifying different types of violence and positive development assets that Spanish adolescents use in their video-capsule scripts. Methods: A thematic analysis of the Lights4Violence video capsules was carried out. Open coding was used to identify violence patterns. A deductive analysis was used to identify student assets using the “Positive Youth Development Model”. Findings: Adolescents describe different patterns of violence, such as psychological violence, sexist violence or verbal violence that is present on the scripts. However, they showed themselves capable of resolving these situations using language and personal empowerment skills as resources. Family, friends and community were identified in adolescents’ scenarios as the most frequent assets to address situations of conflict. Conclusion: Adolescents can promote healthy relationships using protective factors against violence. Interventions that use this approach can potentially be useful in preventing violence.
