Utilising a Behaviour Change Model to Improve Implementation of the Injury Prevention Exercise Programme in Schoolboy Rugby Union.

The Health Action Process Approach (HAPA) is a behaviour change model showing promise in positively changing youth sport coaches' injury prevention behaviours. This study incorporated the HAPA model into coach training workshops for , an efficacious rugby injury prevention programme. Primary aims were to investigate the effect of the workshop on schoolboy rugby union coaches' (1) perceptions towards injury risk and prevention, (2) adoption and adherence. Secondary aims were to (3) assess the differences in post-season HAPA constructs between workshop attendees and non-attendees, (4) explore associations between HAPA constructs and adherence. In the pre-season, all participants ( = 76) completed a baseline survey, with 41 coaches electing to attend a workshop. Participants completed a post-season survey assessing HAPA constructs and adoption and adherence throughout the season. The workshop did not affect coach perceptions of injury risk and prevention. Attendees had significantly greater rates of adoption (95% vs. 54% χ = 17.42, < 0.01) and adherence (median = 2 sessions vs. ≤1 session per week; z = 3.45, = 0.03) than non-attendees. At post-season, attendees had significantly greater task self-efficacy (z = -3.46, < 0.05) and intention (z = -4.33, < 0.05) to use . These results support the delivery of coach workshops that utilise a behaviour change model to maximise programme implementation.
