Promoting Adolescent health through an intervention aimed at improving the quality of their participation in Physical Activity (PAPA): Background to the project and main trial protocol

Funded by the European Commission, the Promoting Adolescent health through an intervention is aimed at improving the quality of their participation in Physical Activity (PAPA) project revolved around the potential of youth sport to promote children's mental and emotional health and physical activity engagement. A theoretically grounded coach education training programme (i.e. Empowering Coaching™), which was designed to create a sporting environment which was more positive and adaptive for young children, was customised for grassroots soccer, delivered and evaluated via a multi-method cluster RCT across five European countries; namely, England, France, Greece, Norway and Spain. In this article, a key part of the protocol of this large and multi-faceted project is presented. The ethical standards and procedures, characteristics of the population targeted and overall study design, and core self-report questionnaire measures completed by the players are described. Information is provided as well on the translation principles and procedures and data-collection procedures adopted in the PAPA project. © 2013 © 2013 International Society of Sport Psychology.
