THE EFFECTIVENESS OF HEAD RESTRAINTS: AN ANALYSIS OF TEXAS DATA

The primary objective of the report was to determine the injury reducing effectiveness of head restraints in rear impact collisions. Three categories of injuries were analyzed from records on the 1972 Texas accident data set. Multi-dimensional contingency table analysis was used to control for the confounding effects of four variables (vehicle damage severity, driver age, driver sex, and vehicle size). In addition, side impact collisions served as a control group to remove any biases in the raw data. The study found significant effectiveness rates in all three categories of injuries after controlling for the presence of confounding effects.
