|Purpose: ||This ground-breaking three-year project calls for putting in place a series of activities to document the issue of sexual assault on very young girls and the impact on their mothers. Three key activities are planned: (1) piloting an intervention program; (2) developing and piloting a training program for practitioners involved in this issue, based on an integrated approach; and (3) making the training program widely available. All these initiatives will be assessed on an ongoing basis at every stage of the project, which ultimately seeks to improve the living conditions of young girls below age 12 who have been sexually assaulted, as well as their mothers. The Centre dexpertise en agression sexuelle Marie-Vincent will use this combined scientific and practical approach to draw the attention of intervention centres in Quebec and other provinces. The innovative nature of the project and the wide range of knowledge transfer measures will promote its dissemination nationally and internationally, particularly in Francophone communities.
