Despite long-standing concerns over self-reported measures of media use, media research has relied heavily on self-reported data. This study not only examined discrepancies between survey and logged smartphone data but assessed whether correlational outcomes using self-reported measures produce greater or smaller effect sizes compared to outcomes using logged measures. College students (n = 294) and MTurk workers (n = 291) provided self-reported and logged data of smartphone use over seven days. The correlations we examined involved four psychosocial contexts, including bridging, bonding, well-being, and problematic use of smartphones. The results showed that the effect sizes of correlations using self-reported data tend to be smaller compared to those using logged data. We believe that this is a hopeful message to the field. This could mean that extant survey results have not erroneously inflated communication findings and that communication researchers still have a lot to reveal with further refined measures.

好消息！交流发现可能被低估了：比较效应大小与自我报告和记录的智能手机使用数据

尽管长期以来人们一直对自我报告的媒体使用情况感到担忧，但媒体研究在很大程度上依赖于自我报告的数据。这项研究不仅检查了调查数据与记录的智能手机数据之间的差异，而且评估了使用自我报告的指标得出的相关结果与使用记录指标得出的结果相比，是产生更大或更小的效应量。大学生（n = 294）和MTurk工作人员（n = 291）在7天内提供了智能手机使用情况的自我报告和记录数据。我们研究的相关性涉及四种社会心理环境，包括桥接，联结，幸福感和智能手机的使用问题。结果表明，与使用记录数据的相关性相比，使用自报告数据的相关性的影响大小往往更小。我们认为这是向实地发出希望的信息。
