Details of injury on accident reports were compared with those later remembered by the victims in interviews, to determine if the recall period could be increased without jeopardizing accuracy, and to identify a possible optimum length of recall time. A sample was selected from persons involved in injury-producing motor vehicle accidents in Durham, Orange, and Wake counties of North Carolina, February 1966-February 1967. Detailed statistical data are tabulated. The study indicated that the optimum recall period for estimating the total number of persons injured in motor vehicle accidents is less than three months. This is a conservative choice, since the bias component of relative root mean square error, which is a function of the ability of a responder to recall a motor vehicle injury, increases over time at a rate greater than that estimated from the methodology study.
