Full details of the data collection methods are provided in the published article. If an EMA survey was delivered at the end of the introductory appointment or during an interim appointment, participants had the option of completing it as a practice survey with the research team. These responses were discarded from analyses and have been omitted from the current dataset. The DataAnalyzer software (version 1.15.1; movisens GmbH, Karlsruhe, Germany) calculated steps with a 60-second resolution. The raw data was aggregated (using the "SUMIFS" function in Microsoft® Excel® for Microsoft 365 MSO, Version 2502 Build 16.0.18526.20416 64-bit) to obtain the length of time in minutes that participants were not wearing the activity sensor in the 15-minute window before (Nonwear_before) and after (Nonwear_after) the EMA survey, as well as the number of steps in the ± 15-minute window around the EMA prompt (Concurrent_PA). This aggregated data is presented in the current dataset.
