The PsyTool project is a collaborative partnership that allows a group of stakeholders from different sport backgrounds to collaborate in the establishment of a network to take full advantage from the implementation of the Sport Psychology as a strategic tool to promote integrity and to tackle violence, discrimination, intolerance and match-fixing among young practitioners of grassroots sports. This is because sport, which makes an important contribution to the EU strategic objectives of solidarity and prosperity, is confronted with a number of threats from which athletes, particularly young athletes, and citizens in general, need to be protected, such as violence, any kind of discrimination, intolerance and even the manipulation of results.In this context, the specific objectives of the PsyTool project are the following:• Obtain more objective data on the impact of violence, discrimination, intolerance and even match-fixing among young practitioners of grassroots sports and to identify good practices applied at European level. • Create educational and innovative tools based on sport psychology to promote integrity and to tackle these harmful factors.• Train “Agents of change” for recognizing potential dangerous situations and for reacting in an adequate way.• Prove this new approach and test its results on the field (over young practitioners of grassroots sports) through a pilot experience.• Disseminate, extend, transfer and sustain the use of the new tools developed. Therefore, the PsyTool project takes account of the social, educational and cultural functions inherent in sport and it looks for to complement and to enrich the European policies in this field, bringing innovative approaches for promoting integrity and for fighting against violence, discrimination, intolerance and match-fixing among young practitioners of grassroots sports, thanks to the use of Sport Psychology as a strategic tool of high value for prevention and training.
