We present the dataset for the article "Never miss a beep: Using mobile sensing to investigate (non-)compliance in experience sampling studies." The data were collected as part of the Smartphone Sensing Panel Study and include more than 25,000 observations from N = 592 participants collected over two 14-day experience sampling periods that included continuous mobile sensing. Demographic and technical variables (e.g., smartphone manufacturer, and Android version of the smartphone) that were not used for the data analyses were removed for privacy reasons. The datasets are documented by a comprehensive accompanying codebook. Additional materials (e.g., preprocessing and analysis code) can also be found at https://osf.io/jw3bn/. Further details on the variables provided and the associated study procedures can be found in the journal article: Reiter, T., & Schoedel, R. (2023).
