A practical approach for applying best practices in behavioural interventions to injury prevention.

Behavioural science when combined with engineering, epidemiology and other disciplines creates a full picture of the often fragmented injury puzzle and informs comprehensive solutions. To assist efforts to include behavioural science in injury prevention strategies, this paper presents a methodological tutorial that aims to introduce best practices in behavioural intervention development and testing to injury professionals new to behavioural science. This tutorial attempts to bridge research to practice through the presentation of a practical, systematic, six-step approach that borrows from established frameworks in health promotion and disease prevention. Central to the approach is the creation of a programme theory that links a theoretically grounded, empirically tested behaviour change model to intervention components and their evaluation. Serving as a compass, a programme theory allows for systematic focusing of resources on the likely most potent behavioural intervention components and directs evaluation of intervention impact and implementation. For illustration, the six-step approach is applied to the creation of a new peer-to-peer campaign, Ride Like a Friend/Drive Like You Care, to promote safe teen driver and passenger behaviours.
