The main objective of the study is to investigate if a video intervention can help increase knowledge, decrease risky behaviours on the hill, and reduce injury risk in students who participate in ski and snowboard school programs. The study design is a cluster randomized controlled trial where participating schools will be randomized into either an intervention or control group. The intervention video will contain an injury prevention and safety promotion component for skiing or snowboarding. The control group will receive the standard orientation video that many schools typically provide for students prior to their ski/snowboard outings in previous years.
