The objective was to study the effectiveness of a brochure and video at improving skiing and snowboarding knowledge. Sixty-nine Grade 7 students were randomised to an educational intervention (n = 35) or control (n = 34) group. The intervention group viewed an injury prevention video aimed at improving skiers and snowboarder's knowledge, attitudes and behaviours about ski and snowboard safety and received a brochure. The control group participated in a teaching session and had a simple question and answer session about snow sports. Pre- and post-tests were administered and injuries during four trips were documented. Pre-test scores were similar between the two groups. Compared with the control group, there was a significantly greater improvement in post-test scores among the intervention group (WMD: 2.1; 95% CI: 0.19-4.01). There was no significant difference in injury rates (RR: 0.49; 95% CI: 0.04, 3.39). All injuries were minor and did not require medical attention. The intervention aimed at youth skiers and snowboarders appears to be effective at improving knowledge, attitudes and behaviours of skiing and snowboarding safety.
