Outdoor, adventure and experiential education programs that feature challenging tasks such as rock climbing or wilderness trekking are often intended to facilitate group cohesion. Despite this, far more attention has been paid to physical risk management than to group and individual behaviour. This is the first book to address this vitally important aspect of outdoor education. It explains how to manage and interact with groups and how to mitigate negative behaviours. Outlining key theory and evidence-based training practices, it is vital reading for students on outdoor and adventure courses, and for practitioners looking to enhance their clients' experiences or train instructional staff.
