Objective: To examine the simultaneous contribution of multiple factors associated with parents' use of booster seats.
Methods: Using the theory of planned behaviour framework, constructs of the theory were tested for usefulness in predicting self-reported intent and behaviour with respect to parents' use of booster seats. Through the use of structural equation modelling, the study demonstrated the most significant predictors of the intent to use a booster seat and reported use of booster seats in a Canadian sample (n=1480) of parents of school-aged children, 4-9 years.
