LARS&LISA in the Municipal Health Strategy - Description of a Project for the City-Wide Implementation of a Prevention Programme in Schools Given the high prevalence of mental health problems, their prevention in children and adolescents is an urgent task. In Braunschweig, a city-wide survey of adolescents as part of Communities That Care (CTC) revealed elevated levels of depressive symptoms, prompting a search for evidence-based, universal prevention measures. The CTC Steering Committee chose the universal, school-based, cognitive behavioral depression prevention program LARS&LISA. This article presents the theoretical foundations, development, content, and evidence of LARS&LISA and describes the first two phases of a community project ("PsyWo") for the citywide implementation of the program. The project includes the recruitment, training, and supervision of group leaders, as well as organization, implementation, and evaluation of the program. In project phase 1, group leaders received intensive training, and the program was implemented in nine school classes in parallel. Phase 2 focused on preparing the city-wide implementation while optimizing the use of human resources. To this end, the group leader training was shortened and effort needed to prepare for the sessions in schools was optimized. To date, over 50 group leaders have been trained and almost 600 adolescents in 14 schools and 34 classes have been reached. This project demonstrates the high potential of municipal, evidence- based, universal prevention as well as challenges for the city-wide implementation of prevention programs such as LARS&LISA.
