本研究评估了日记法测量车载广播听众的准确性，通过三个月内多种测量方法（包括录音）对比，发现日记法存在偏差。
Abstract Despite the importance of diary measures, the dominant method used to measure radio audiences, few studies have been published concerning the accuracy of those measures. Several different measures of car radio audiences were conducted over a three-month period, including an audio tape of each subject's car radio listenership, in order to assess the accuracy of diary measures of car radio audiences.
