心理学家在量化手机使用情况时通常依赖于自我报告数据，尽管几乎没有证据表明它的有效性。在这篇文章中，我们探讨了使用自我报告的估计与实际智能手机使用相比较的准确性。我们还包括处理和可视化这些数据的源代码。我们将23名参与者在两周内的实际智能手机使用情况与自我报告的估计值和手机问题使用量表进行了比较。我们的结果表明，除非需要更高的数据分辨率，否则估计使用智能手机的时间可能是一个足够的衡量标准。关于一个人在一天中使用手机的次数的估计与实际智能手机使用没有相关性。估计的使用时长和使用次数与手机问题使用量表都不相关。我们的结论是，在心理研究中，估计的智能手机使用情况应该谨慎解读。
Psychologists typically rely on self-report data when quantifying mobile phone usage, despite little evidence of its validity. In this paper we explore the accuracy of using self-reported estimates when compared with actual smartphone use. We also include source code to process and visualise these data. We compared 23 participants’ actual smartphone use over a two-week period with self-reported estimates and the Mobile Phone Problem Use Scale. Our results indicate that estimated time spent using a smartphone may be an adequate measure of use, unless a greater resolution of data are required. Estimates concerning the number of times an individual used their phone across a typical day did not correlate with actual smartphone use. Neither estimated duration nor number of uses correlated with the Mobile Phone Problem Use Scale. We conclude that estimated smartphone use should be interpreted with caution in psychological research.
