Abstract
This study examines the accuracy of a survey question about the number of times a subject has been arrested. Specifically, the study answers questions dealing with extent of response error, random versus systematic response errors, the reasons for response errors (lapses in memory and motivational factors that lead to under- reporting or overreporting), and the extent to which the survey response is an adequate substitute for actual data. The results demonstrate that there is a considerable amount of response error in the measure and that both memory lapses and motivational factors contribute to it. Some strategies for dealing with the problem are explored.
