There has been little critical evaluation of which methods achieve the desired results in health education. Using purchase of proper infant auto restraint devices as an objective, we assessed the effectiveness of three educational approaches. Only 37% of control families had purchased an acceptable car seat, compared to 54% of those who received descriptive literature alone, 71% of those that received literature and had been shown a descriptive film, and 60% of those who were given literature, shown the film, and been provided with a demonstration of the seat. Purchase of car seats was positively correlated with social class and knowledge of auto safety, but not with a history of auto accidents. Utilization of auto restraint devices is an example of how social learning theory can be applied in health education.
